Du Fan glanced at Ren Ziwen with a half-believing expression and said, "Then tell me, what are the advantages of this walkie-talkie?"

"First, the signal is good..."

The first sentence Ren Ziwen said made Du Fan roll his eyes several times.

"The most important thing is that the walkie-talkie I researched ignores the constraints of space. No matter how far apart the people on both sides do not even have to consider whether they are on the same interface. As long as the time they are in is synchronized, they can have conversations through the walkie-talkie.

Also, I am now studying video intercoms, and I believe it will not take too long to come out."

"So awesome?" Du Fan was stunned when he heard this.

"It's a must!" Ren Ziwen looked proud.

"Give me one too." Du Fan thought for a while and added: "One is not enough, at least ten."

"Not that much, I've only prepared one for you." Ren Ziwen said, taking out another stone tool and throwing it out.

"How do you use this thing? Dial?" Du Fan said while playing.

"It's not as complicated as you said. You don't have to do anything. Just pick it up and talk directly. However, this kind of intercom can only be regarded as a semi-finished product. It can only be used one-on-one between two intercoms, and the subsequent needs to be improved." Ren Ziwen explained.

"It means that if you talk to me, Xiao Yun and Anu, you have to prepare three walkie-talkies? And the walkie-talkies you gave me can only talk to you alone?" Du Fan said.

"Yes, that's what it means, but I have found a way to improve it. As long as the theory is realized, the intercom will be almost the same as the phone. Everyone only needs a stone tool, and they can call whoever they want." Ren Ziwen said with anticipation.

"Okay, you can study it slowly, I'm optimistic about you." Du Fanzou gave Ren Ziwen an encouraging look. He was completely convinced by the scientific research spirit of this test maniac. He was so thoughtful. The key was not just a fantasy. He could produce some scientific research results every time.

Ren Ziwen raised his arm and threw it to Du Fan a storage bag, saying, "Give it, according to your request, the ghost guide rod has removed the dust, and now it has returned to its original appearance and has reached a true top-grade level.

I partially sealed the Supreme Ruoshui Sword. Now the power of this magic weapon is between the top and the acquired top. I only need to use a little trick to unseal it immediately.

There are twenty pairs of memory talismans here. Please note that two of the individual memory talismans are positioned, and the location coordinates are here. If you are in danger outside, you and Bailichou can immediately crush these two memory talismans and then return to the Governor's Mansion."

"I won't say polite things to you." Du Fan smiled, and then thought of something. He slapped the storage bag with one hand and immediately flew out three pairs of memory treasures. He took apart these memory treasures one by one, and then handed the three separate memory treasures to Ren Ziwen.

"Brother Du, you are..." Ren Ziwen was puzzled.

"If nothing unexpected happens, I will return to Jiuzhou Great 6 soon and then return to Qixia Sect. After arriving at the sect, I will be completely safe and have no worries.

At that time, I will crush all these three memory talismans to use for positioning. If you are bored here, you can go to my place to take a look. Xiao Yun and Anu are the same." Du Fan smiled slightly and explained this.

Ren Ziwen's eyes lit up and he smiled and said, "This idea is good. With memory Fu Mu, from now on, you and I can travel back and forth between two big sixes. But to be honest, there are more things like Huangtian Lingmu, and if you can, you still have to find a way to get more."

"I know this without saying it. It's just that this is rare in the world and must be a great opportunity. Of course, if you really encounter it, no matter how much the price it costs, I will get it..." Speaking of this, Du Fan paused, his eyes fell on Ren Ziwen, and said, "This time, you haven't forgotten to use memory talisman wood to locate it in that strange space, right?"

"Of course I haven't forgotten, I've already located it."

"Then... try?" Du Fan's eyes lit up.

"Forget it, maybe some variables will appear. I will study it slowly after you leave." Ren Ziwen shook his head.

"Yeah, that's fine."

"Brother Du, what method do you plan to go back to Jiuzhou 6?" Ren Ziwen asked in a flash.

"I don't know yet, but it's soon." Du Fan suddenly thought of Tan Xi, who was still unconscious. This was also one of the reasons why he was eager to use the time and space tripod. Only when the time of that strange space passed can Tan Xi leave enough time to wake up.

"Is it reliable?" Xiao Yun couldn't help but let it in.

Du Fan glanced at the woman, smiled and said, "Don't worry, it's quite reliable."

"Young Master." Anu's figure flashed a few times and came to the three of them. Bailichou followed in the distance, and he was also very fast.

"The peak of the sixth level of Qi Refining Period!" Du Fan immediately split a wisp of divine thought, swept Bailichou's body, and his expression changed slightly.

"Are everything done?" Ren Ziwen smiled at Annu and asked in a warm voice.

"Well, these storage bags contain materials related to alchemy and weapon refining. Among these two spirit beast bags are the second-level monsters and mid-level monsters that the young master wants."

Annu handed a lot of bags to Ren Ziwen, but Ren Ziwen only left two spirit beast bags, and the other storage bags were thrown directly to Du Fan.

Ren Ziwen picked up a bag of spirit beasts and shook it for a while. The black light flashed. A monster that looked like a sheep and a deer fell to the ground. The beast's eyes were open, but it looked a little depressed. There was a talisman on the top of the head for suppression.

Without saying a word, Ren Ziwen threw the monster into the space-time cauldron and started operating.

"Pupil, pay homage to Master." At this time, Baili Qiu rushed over and immediately gave Du Fan a deep bow. A hint of joy and peace of mind flashed in the little guy's eyes, but he was introverted and indifferent, but he did not say a greeting.

"No need to be polite. You can prepare for it first, and I will take you away later." Du Fan said with a smile.

"Yes, Master." Baili Qiu bowed again and walked away, directly ignoring Ren Ziwen, Xiao Yun and others.

Seeing this, Anu was a little angry. When she wanted to say something, she was grabbed by Xiao Yun.

"Brother Du, come here." Ren Ziwen suddenly shouted.

"What's wrong?" Du Fan walked over.

"A time and space shuttle has been completed, and the stay time of this monster is three years and ten months." Ren Ziwen said.

"Well, this time is the same as the time of the last experiment. Eliminate the space-time marks and conduct a secondary shuttle."

Ren Ziwen nodded, took out some materials, and after some operation, he took out several high-level spirit stones again to activate the space-time tripod.

"Seven years and eight months!" After a moment, Du Fan and Ren Ziwen looked at each other and said in unison.

"It seems that our previous guess is fine. The second time stayed is just twice as much as the first time. I don't know whether the extra time will be added or multiplied." Du Fan looked thoughtful.

"Confirm again." Ren Ziwen shook off the monster from another spirit beast bag, threw it into the time and space tripod, and then began a skillful operation.

"The first time of this monster's shuttle was two years and eleven months, and the second time was five years and ten months. The guess that the time was twice as long can be confirmed." Ren Ziwen concluded and said, "Brother Du, what was the last time you shuttled?"

“Four years and eleven months.”

"So, your time and space journey will last at least nine years and ten months. Will you become a powerful Nascent Soul Power after I blink my eyes later?" Ren Ziwen looked strange.

"How is this possible? At most, it is the middle stage of the Golden Pill." Du Fan shook his head and laughed, but he was thinking in his heart: "The Nascent Soul Stage... is so far away. Even if I practice all the Lingshu True Sutras in one breath, I probably won't reach that level. Besides, the Lingshu True Sutras are so precious, how can I ruin it now? This thing is less than a volume after one volume of practice."

"Think about it carefully and see if there are any other needs. It's still too late to prepare now, but it's too late to enter. After all, there's only one chance to steal time in a short period of time." Ren Ziwen instructed.

"No more." Du Fan thought for a while, feeling that there was no problem. He immediately shook his body and appeared in the space-time cauldron.

Ren Ziwen took out several high-level spirit stones and tucked them into several grooves in the time and space cauldron. Du Fan used a magic trick to hit it.

...

Du Fan felt that his eyes turned black and his head sank, and he lost consciousness.

Maybe it took a long time, or maybe it was just a moment, when he recovered as usual, he appeared in a wonderful world, where there was no sky, no earth, no upper or lower, and there was only endless water-blue spots of light, which caught his eyes in a vast world.

"It's strange. No matter it is water spirit, the surrounding scenes, or the feeling in my heart, there is no change. Those who come through the two times will not be the same space. I left in a hurry just now, and I forgot to communicate with Ren Ziwen..."

Du Fan's eyes and spiritual thoughts swept around, and after a moment, he came to such a conclusion.

"The time of staying this time is destined to be very long. Why not go to the edge of this space like last time?" Du Fan thought so in his mind, and suddenly his body shook and rushed towards a sure direction.

Maybe he was lucky, or maybe he soared after he advanced to the Golden Elixir Stage. In less than ten days, he appeared on the edge of this world.

The edge of the world is still an existence similar to a space barrier, which is almost transparent and difficult to distinguish with the naked eye. Only divine thoughts can be detected. If the body hits it, it will be bounced open by the barrier.

Behind the barrier, most areas are pitch black tones, which look very distant and deep.

It seems like a place that is close to the far and wide, with stars scattered randomly in the starry sky, as if there is no rule.

It is not until the distance that we can see the flowing of the galaxy and surrounding the stars. It is countless stars gathering together, outlining patterns that are both abstract and vivid. In the endless darkness, it seems to exist freely without the constraints of time and space.

Du Fan stopped and looked at it for a long time. Although it was not the first time he had appreciated this strange scene, his heart was still full of shock and even fear at this moment. He suddenly realized that no matter what kind of thing, it seemed so insignificant in the face of endless time and endless space. A person, for the vast universe, could not even be considered a speck of dust.

After a cup of tea, Du Fan withdrew his gaze, retreated for several miles, released spiritual insects and beasts such as black wood silkworms, single-legged birds, and threw out resources such as empty mulberry leaves, magic cores, and dogwood fruits, allowing them to practice on their own, while he himself sat cross-legged and calmed his mind.

For Du Fan, looking at the edge of the world is purely a whim, and it has no substantial meaning for him. In his plan, after traveling to this space, the first thing he needs to do is to consolidate his cultivation and break through the stability period.

When his condition was adjusted to the best, his wrist suddenly turned around, and several light green demon pills and corresponding amounts of elixir water appeared. Without saying a word, he immediately swallowed a demon pill and a bottle of elixir water, and then his martial arts were used to refine it.

One hour later, the demon pill was refined and the stability period was moved forward as expected.

Du Fan looked inward with his divine thoughts, felt his own changes, and measured the energy intensity of the demon pill and the body's ability to withstand it. After a while, he came to a conclusion that even if he was conservative, it would be no problem to swallow twenty or thirty demon pills at the same time.

He waved his arm and swallowed the remaining twenty light green demon pills and the same amount of elixir water in his hand into his stomach in one breath. So more than twenty elixir waters slowly rotated around the elixir magic pills in his internal organs.

One hour later, he had refined these more than 20 light green demon pills.

Next, he directly took out forty light green demon pills and forty bottles of elixir-making water and swallowed it in one bite.

A month later, Du Fan successfully broke through the stable period of the early stage of the Golden Pill and truly entered the early stage of the Golden Pill. If there were no major accidents, there would be no danger of falling realm. At this level of the Golden Pill, he had completely stood firm.

For Du Fan, who took the excessive stability period of demon pill, before this, the time for breaking through the stability period was very regular and fixed.

For example, when he had just advanced to the Great Perfection of Qi Refining Period, the stability period lasted for half a month, the early stage of foundation building was one month, and the middle stage of foundation building was two months.

Although he had other opportunities in the late stage of foundation building and the Great Perfection of Foundation Building, and did not take too long, the rules of this stable period were already very obvious. When only taking the demon pill, the duration would be doubled for every increase of one realm.

According to this rule, in the early stage of the Golden Pill, if he wanted to break through the stability period, he would have to take at least sixteen months of demon pills. However, the actual situation was that he had only taken one month to pass the stability period in a leap manner.

The reason for this phenomenon must be related to the Lingshu True Sutra and the Danhai Sutra. It seems that his cultivation qualifications have really changed from being the number one waste in the world to the current cultivation genius under the transformation of these two heaven-defying scriptures.

Du Fan slowly exhaled and then opened his eyes.

"Before continuing to practice, it is necessary to study the essential oil of the elixir and the golden wind jade dew."

Du Fan waved his sleeves and showed three sets of experimental instruments that he had not used for a long time and placed them side by side in front of him.

"The four most common types of elixirs to improve cultivation in the Golden Pill stage, Jinsheng Dan, Haoyue Dan, Jingyang Dan, and Ninghua Dan are suitable for the early, mid-stage, late stage, and Great Perfection of the Golden Pill. Forget it, even if this elixir is refined into elixir essential oil, it will not be too effective for me now. Let's start researching directly from Haoyue Dan."

"Even if it is a bit troublesome to use the essential oils of the Golden Elixir stage, I can probably still study them with my biological attainments, but it is hard to say that further up.

In the long run, the Golden Wind Jade Spirit Liquid is the right way and can always accompany me to grow. Elixir essential oil is just an excessive means after all, and will be eliminated sooner or later.

Fortunately, I have already gained some insights into the cultivation plan of the Golden Wind Leaf and Jade Dew Flower, and after repeated deductions, it is extremely feasible. However, in a short period of time, the Golden Wind Jade Dew Spirit Liquid cannot be produced on a large scale, so the cultivation of Golden Wind Leaf, Jade Dew Flower and the extraction of elixir essential oils need to be carried out simultaneously."

"When it comes to cultivating golden wind leaves and jade dew flowers, it starts with the holy water where the fallen leaves return to their roots..."

When he was on the Lost Leaf Island, Xiao Yun was still a killer of the fallen leaves returning to the roots. Du Fan and this woman once entered the temple where the fallen leaves returning to the roots. Xiao Yun's ultimate goal was to use the holy water to restore her appearance. After the woman's appearance was restored, the holy water was not completely used up, so Xiao Yun gave the remaining holy water to Du Fan like a Buddha by offering flowers.

Du Fan raised his hand and grabbed it, and the bottle containing the holy water appeared in his hand. He looked at the water in the bottle, smiled faintly, and whispered: "The holy water has the function of regenerating muscles and corruption and reshaping the body. Haha, to put it bluntly, isn't it just promoting cell division and growth..."

Golden wind leaves and jade dew flowers have no seeds and cannot be cultivated and mass-produced through normal channels. However, this matter is not unsolvable for the genius biological scientist Du Fan. A professional term he first thought of was...nutritional reproduction!

Nutritional reproduction is a type of plant reproduction method. It does not pass sexual pathways, but uses nutrient organs such as roots, leaves, and stems to reproduce offspring. This reproduction method not only maintains the excellent characteristics of the cultivation, but also has a faster reproduction.

Simply put, it is to cut a small piece of rhizome or branch from the golden wind leaves and jade dew flowers, and then place it in a special environment to expand and grow. In the end, this small piece of rhizome or branch will become a brand new spiritual herb.

This is nutritional reproduction, or asexual reproduction, without any seeds at all! (To be continued.)
