At this time, Wu Xian outside the light ball in the Illusion World couldn't help but laugh when he saw their joy.

The purpose of his light on the illusory world light ball just now was to temporarily open up shared authority to his illusion souls, so that they can study martial arts more efficiently.

"Next, keep the time flow rate differential and wait slowly."

Wu Xian murmured at the illusory world light ball.

Then his figure disappeared into the chaotic void.

In reality, Wu Xian opened his eyes.

After thinking about it, he walked out of the manor and walked towards Tiangong Pavilion.

Tiangong Pavilion, in the spiritual material warehouse.

Wu Xian was talking to his mother-in-law at this time.

"There are almost all these spiritual materials you need in the spiritual material library, but there is not only one spiritual material library here, but I'm afraid there is not even in the entire treasury of the Later Shang Kingdom, or even the entire Nanhuang practice world."

The mother-in-law looked at the list of spiritual materials in her hand and shook her head to Wu Xian and said.

"What kind of spiritual material is it?"

Wu Xian asked.

"The 2000th year divine thunder wood." said the mother-in-law, "This year is too high. Even among the third-level spiritual materials, this year is very precious. Although our country has been established for a long time, we have never seen the 2000th year divine thunder wood. As far as I know, in the entire Nanhuang practice world, only Wanbao Tower collected a 800-year-old divine thunder wood three hundred years ago, but that divine thunder wood is only ten centimeters high. You not only need 2000 years, but also need two at the same time. This is impossible. No force in the entire southern practice world can produce it."

Wu Xian's eyes showed disappointment.

The 2000-year divine thunder wood is the wing bone material of the Xuanthunder magic wing. Without two 2000-year divine thunder woods, the 2000-year divine thunder woods cannot be manufactured and completed.

He thought for a while, then looked up and asked, "Are there any seedlings of divine thunderwood in our spiritual material warehouse? The seeds are OK?"

"Seedlings? Seeds?" the mother-in-law said in a hilarious way, "You don't want to use the vital spiritual liquid of the first-level medium-grade spiritual cultivation bottle to give birth to the divine thunderwood, right?"

"But the lowest level of the divine thunderwood is also the first-level top level. The first-level middle-level Vitality Liquid may have a great discount. If you want to use Vitality Liquid to give birth, it will probably take 200 years to give birth to a 2000-year divine thunderwood."

The news of the birth of the first-level mid-grade spiritual bottle was already known by the old people from the Shang Kingdom through various open and secret channels. As she was close to Wu Xian, she guessed that the first-level mid-grade spiritual bottle should have been created by Wu Xian as soon as she learned the news.

Especially when the person above recently ordered her to give Wu Xian the best discount to her in terms of spiritual materials, she would try her best to give Wu Xian as much as possible, and she was even more sure that the first-level medium-grade spiritual bottle was created by Wu Xian, otherwise how could the above give Wu Xian the benefits for nothing?

After hearing what his mother-in-law said, Wu Xian did not deny: "I am already in the foundation-building realm, and my life span is nearly 500 years. It is not too much to spend 200 years to cultivate two 2000-year divine thunder woods."

When the mother-in-law heard this, she couldn't help feeling helpless.

However, when she thought of the foundation-building monk in front of her, when she was only 16 years old this year, she felt that what Wu Xian said seemed to be reasonable...

"Okay, wait."

The mother-in-law stood up, turned around and walked towards the depths of the spiritual material library. After a while, when she came out, five palm heights had already appeared on her hands, which were dark blue and dark blue thunderous small tree seedlings flowing on the main trunks and branches.

"This is all the divine thunderwood seedlings in the Ku." The mother-in-law put the divine thunderwood seedlings on the table, "Just give me a first-level top-grade spirit stone."

"One piece of first-level top-grade spirit stone?"

Wu Xian was stunned.

This is a bit too low.

"The divine thunder wood is not very useful. One piece of first-level top-grade spirit stone is enough to buy it, so take it!"

The mother-in-law said indifferently.

"Thank you, my mother-in-law."

If you have a advantage, you won’t take advantage. Besides, your mother-in-law won’t harm you, so Wu Xian smiled and handed over the spirit stone and bought it.

When the mother-in-law saw him take it away, she nodded with satisfaction.

In fact, even if it is a seedling, it requires three first-level top-grade spirit stones to buy it. The reason why my mother-in-law sold five seedlings of divine thunderwood to Wu Xian was naturally because she could do this because she had the orders of her superiors as a guarantee, although she was willing to do this.

Wu Xian, who got the divine thunder wood, stopped staying for a long time and immediately returned to his manor.

He called out the drawing information of Shiyuan and Yuling Bottle in his heart, and then the drawing text of Shiyuan and Yuling Bottle appeared in his right eye.

...

[Equipment drawing name: Shiyuan and Spirit Bottle]

[Grade: Second-level low-grade magic weapon drawing]

[Element 1: Time Source (second-level lower-grade) - Continuously absorbing the power of time between heaven and earth for seven days and condense a drop of time source spiritual liquid, which can accelerate the time flow rate of spiritual plants, accelerate the growth time of any layer of plants for 50 years, and can be repeated superimposed.]

It can be used to cultivate spiritual plants that do not enter the flow level and accelerate their growth for up to three years; it can also cultivate lower-level spiritual plants to accelerate their growth for up to 360 days; it can also cultivate medium-grade spiritual plants to accelerate their growth for up to 120 days; living creatures can also eat them to recover their injuries.]

[Review: grow quickly!]

...

[Evolution of the drawing entry: Time Source (second-level lower-grade)]

[Evolution branch: Upgrade the level of the time source spiritual liquid from the second-level lower-level lower-level to the second-level middle-level middle-level, so that it can accelerate the growth time of any level of spiritual planting for 100 years, and can be repeatedly superimposed.] (Spend five second-level upper-level spiritual stones)

[Abnormal evolution branch: Not opened.] (It takes a first-level top-grade spirit stone to open it)

[Evolution of the drawing entry: Yuling (first-level medium-grade)]

[Evolution branch: Raise the first-level middle-level Vitality Liquid to the first-level top-level, enhance the vitality power in the Vitality Liquid, so that it can accelerate the first-level low-level spiritual planting for up to three years, first-level medium-level spiritual planting for 360 days, first-level high-level spiritual planting for 120 days, creatures can also use and recover their injuries.] (Spend three first-level medium-level spiritual stones)

[Abnormal evolution branch: Not opened.] (It takes a first-level top-grade spirit stone to open it)

...

Wu Xian's eyes fell directly on Shi Yuan's evolution entry.

"evolution!"

Wu Xian took out five second-level top-grade spirit stones and said decisively in his heart.

The reason why he bought seedlings of the divine thunderwood was naturally because he wanted to accelerate the growth of the divine thunderwood through time-source spiritual liquid to allow it to grow smoothly into the 2000-year divine thunderwood.

However, at present, a drop of Shiyuan Spirit Liquid can only accelerate the growth time of 50 years. If you want to accelerate this speed to 2000, it will take at least 60 days to complete.

If Wu Xian wants to get the Xuan Lei Magic Wing as soon as possible, he can only improve the effect of the Shiyuan entry first.

As soon as he gave the order in his heart, the spirit stone in his hand instantly shattered into sand. At the same time, a large amount of inheritance information about how to improve the time source entry, including new time patterns.

When new patterns of time poured into his mind, Wu Xian frowned immediately. The nausea caused by the turbulence of time made him feel a little tempted to vomit.

However, the vomiting feeling was still within his acceptable range, so he forced himself to endure it.

After about a quarter of an hour, he opened his eyes and couldn't help but breathe a sigh of relief.

Then he looked at the Shiyuan entry in his right eye and found that the Shiyuan entry at this time had become an effect of accelerating the growth time of 100 years, and the new evolutionary branch was also updated.

...

[Evolution of the drawing entry: Time source (second-order medium-grade)]

[Evolution branch: Upgrade the level of the time source spiritual liquid from the second-level middle-level level to the second-level top-level level, so that it can accelerate the growth time of any level of spiritual planting for 500 years, and can be repeated.] (Spend five third-level low-level spirit stones)

...

"Open the evolutionary branch!"

Wu Xian took a deep breath.

Now, he has two fourth-level middle-level spirit stones and two fourth-level low-level spirit stones. With these spirit stones, he can completely increase the effect of the Shiyuan entry to a very high level.

After he decided to continue to improve, the spirit stones in his hand shattered into sand again, and the same inheritance information about Shiyuan entry immediately poured into his mind.

He endured a stronger sense of disgust and forced himself to accept the inheritance message.

It took about half an hour before he opened his eyes, and some bloodshot appeared in his swollen eyes.

He looked at the drawing information text in his right eye, and saw that the text about the Shiyuan entry had been updated again, and new content appeared in its evolutionary branch.

...

[Evolution of the drawing entry: Time Source (second-level top-grade)]

[Evolution branch: Upgrade the level of the time source spiritual liquid from the second-level top-level level to the third-level lower-level level, so that it can accelerate the growth time of any level of spiritual planting for 1,000 years, and can be repeatedly superimposed.] (Spend five third-level middle-level spirit stones)

...

“Continue to evolve!”

Wu Xian gritted his teeth and said.

As soon as he finished speaking, an extremely strong sense of time surged into Wu Xian's mind. This time, Wu Xian's eyes turned white and then fainted.

Two days later at noon.

Wu Xian slowly opened his eyes.

"Shopkeeper."

Shadow said, then silently handed him a cup of tea.

Wu Xian sat up in confusion, took the tea and drank a few sips, and then he became a little more awake.

“Where did this tea come from?”

Wu Xian asked.
