The most important thing is that what happened three hundred years ago that he didn't know made the Black Dragon Leader pursue and continue to improve and find out what happened back then. So, did the Black Dragon Leader also lose some memories? Duo'er slept for three hundred years, the girl and Qiusi had crystals, and how did the Black Dragon Leader live for three hundred years against the laws of nature?

Tiankong wanted to break his head but couldn't find out the reason. After returning to his senses, he saw Shuxi's calm appearance, and then he knew that the girl's mood had improved. If she encountered this situation again, she could deal with it calmly. Shuxi also opened her eyes and looked at Tiankong with a smile and said, "Sky, what have you thought of?"

The sky was shaken. If he could easily guess, then the arrangement set by Duoer would not make the Black Dragon dare not attack him. If not, they could kill themselves and study it slowly. Although he didn't know why only he could unlock the secret of the Dragon and Phoenix Necklace, he definitely couldn't do it.

"It's good to think of it. The Black Dragon tried his best to do these things. I don't know how they thought. Alas, we can only fight against those killers. I don't know if they really want to kill me this time, but using so many masters must have a considerable purpose. This light curtain alone may cost a lot. Such a big deal..."

Shuxi gently pushed Tiankong's body and said, "Does the Black Dragon people have a bad mind? If it were me, I would hijack people who are related to you and threaten you. How simple it is, it is easy to say everything you know."

"I know?" A flash of lightning flashed through the sky's mind. It can be said that the speaker was unintentional and the listener was intentional. Shuxi's words made the sky suddenly realize. Since they did not do this, it must be that what they know now has not reached their ideal stage. Only themselves can unlock the secret of the dragon and phoenix necklace. Is immortality just one of the secrets of the dragon and phoenix necklace?

"Shuxi, what else can be more coveted than immortality?" Tiankong suddenly spoke and asked Shuxi. This kind of thing might be something outsiders could wake him up with one word.

"Well, what's the point of immortality? You can only be alone. But what you say is more important than immortality..." Shuxi held his chin and thought, "I can't think of it. Since we can live forever, what else can't be done?"

"Hope that has been sleeping immortal awakens the original heart of the silence. This is the font on the dragon chain. Also, the dragon roars and phoenixes, and the light spreads to the world. This line of small characters. There are sixteen words missing on the phoenix chain, only the small characters are immortal and immortal, and the dry bones are rejuvenated." The sky looked at the desert outside the light curtain and pondered: "But I have seen the phoenix chain, but there are not those sixteen words. It is difficult to know if you can find the 16 words to know the content?"

"The awakening of the original heart when she was silent should be what Duoer said to make me truly awaken. Hope that has been sleeping in immortality should be talking about Duoer. She should have extremely strong strength before she fell asleep. So what about the small words..."

"I remember Duoer said that she had fused the crystals in the phoenix chain, and the phoenix chain obtained by the Qin family was just an empty shell. This may be the reason why the sixteen words on the phoenix chain disappeared. In other words, as long as she fuses the crystals of the dragon chain, the words on it will disappear." The sky slowly inferred along her thoughts.

"Then the small words that did not disappear on the dragon and phoenix necklace should be something that has not happened yet. Simply put, it is something that has not happened. It can also be said to be another secret left by Duoer, a foreshadowing of what is going on. If you merge the dragon chain crystal, that sentence will disappear. But what about the small words?"

The sky frowned and thought, "The dragon roared and the phoenix roared, and the light spreads to the world." According to the literal meaning, the old man said that the dragon and the phoenix will appear in the desert every night on the full moon. Is this the reason? The dragon roared and the wind roared is the blending of dragon and phoenixes, and the light spreads to the world, which is a way to save the world.

‘Life and death are immortal, and the dry bones are rejuvenated.’ It is a long-lasting life that can cure dead bones. It seems that Duo'er has not told him all the real secrets of the dragon and phoenix necklace. And the content she concealed must have an impact on him now. But unfortunately, Duo'er has merged the phoenix chain, and that sentence has disappeared. He has no way to know it now.

Shuxi stayed quietly beside the sky, listening to his own words, and her tongue twisters made her confused. But what was certain was that the sky was looking for a solution to the crisis in front of her.

"So that is to say, Duoer had already integrated the phoenix chain three hundred years ago. So, was Duoer's research direction for the experiment used on her at that time the dragon and phoenix necklace? But she grew up like a normal person without maintaining her original body. In this way..."

"The Star and Moon Empire fell overnight, and only a few people survived. Duoer's experimental subject fell into a deep sleep. Does that mean that the experiment at the beginning was not as successful as Duoer said, but failed. Some irreversible things happened to Duoer, but at that time, they were able to control and apply the perfect method to herself. Is this difficult reason why she slept for three hundred years and then let the black dragon take action and sleep again after waking up six years ago?"

"To conceal this reason, Duoer and the others arranged many clues to find them three hundred years later, engraved words on the dragon and phoenix necklace, leaving relics everywhere for themselves to discover. Only one can discover each place. Knowing that the Fanxing City we discovered before, the Star Brother there told him that he was from three hundred years ago."

The fundamental reason for all the problems is what happened three hundred years ago. What Tiankong couldn't understand is why Duoer didn't tell herself directly, but instead spent so much effort to gradually tell herself some information. How difficult what happened back then was to be too important?

"Oh. Duoer is such a genius. How long does it take to think about such a complicated situation?" Tian Kong woke up and did not think about it in this dead end. After all, this is not something that can be understood by thinking about it. If there are not enough clues, it is impossible to know. The current situation does not allow Tian Kong to let go of his mind and think about it slowly. They may be discovered by the killer at any time in the trap set by the Black Dragon Killer.

"Shuxi, is the medicine I gave you still there?" Tiankong can only use all the resources in his hands to grasp any details.

"Well, here... the sky, the medicine you made in the ancient city, if we..." Shuxi nodded and agreed, but she didn't understand why the sky did not take those medicines that could be improved to ten stars? In this case, wouldn't they have a point in winning?

Tiankong naturally knew what Shuxi was thinking, and said with a pout, "Yes, those medicines can make people raise the height of ten stars in a short time, but they also have side effects. This is why I didn't give all of you calligraphers. The balance is not so easy to break, otherwise the Star Moon Empire, which mastered this prescription three hundred years ago, would have replaced us long ago. The side effect... is that the speed of improving strength will be reduced by 70%. In other words, those who use medicines will spend several times more time improving one star than others."

Shuxi curled his lips and said nothing. No wonder Tiankong did not take the medicine as soon as possible. Although it can make people upgrade to ten stars in a short time, Tiankong only takes time to do it, and there is no need for him to use these medicines with side effects. Those who take these medicines are either dead men of the family or those who have no hope of reaching ten stars for life. Otherwise, a talented person would never take it.

"Okay. Shuxi, come here, I will tell you the distribution of this town. In order to prevent accidents, we must be fully prepared. First of all, we must deal with those killers. What we need to understand is the terrain here. When facing those people, we know that the terrain can give you a lot of advantages. Look..." Sky took off its watch and called out the three-dimensional picture of Chen Xingfan's passing on to him, and explained it concisely with detailed information. What they lack now is time, and Sky dare not delay any longer.

After all, those killers have undergone special training, and it is not difficult to find two people in this small closed space: "How is it, how much does Shuxi master?"

Shuxi was extremely intelligent since childhood and had the help of perception. After explaining it to the sky once, he could remember it in his heart and said, "Well, there is no problem." Looking at the sky, there was a layer of mystery. She now realized that Tiankong had already begun to investigate the town when she was on the road. No wonder they had come here for the first time, Tiankong could freely shuttle like a backup in their own home. This may be the reason why he, as a killer, survived to this day and was always cautious.

"Okay, in the next time, you will be responsible for perception. If there is any accident, tell me immediately. The killers coming from the Black Dragon seem to have experience, and it is probably difficult to meet the solitary ones. Then, seeing that they did not take action as soon as the light curtain appeared, I think the light curtain should last for a long time. And we have to do two things." The sky and Shuxi's body were tightly attached, and the two heads were close to each other, and the strong breath kept stimulating Shuxi, and the cheeks were covered with flowers on its pretty face.

Shuxi nodded and thrust quickly to the center of the earth, pressing his shyness and raising his tender red ears and listening to his words: "First, fighting guerrillas with those killers has a high chance of being discovered, but it is much better than fighting them head-on. It can delay time. Although it is not known how long the light curtain will disappear, we should do our best."

"Second, remember to use all the surrounding terrain, which may not be a head-on fight. And the medicine I gave you will take when I was seriously injured. Remember the skills I told you to save your life. Although they are inconspicuous, they can play a significant role in some cases. Do you never use the secret method of killing the gods and kings when they are not allowed. Remember?" The sky explained what he could think of in a short time, in order to deal with sudden situations. Although it may not happen, it is always good to be prepared. Moreover, once the secret method of killing the gods and kings is used, with Shuxi's current situation, it is absolutely impossible to walk out of here alive.

Shuxi listened to everything about the sky, felt a warm feeling in his heart, covered his hot cheeks and glanced at the sky, fearing that he would find himself looking at him.

"Okay, since that's the case, we'll start. You feel the killer who is alone around you." Tian Kong bent down and picked up Shuxi. It was not that he wanted to take advantage of it, but that Shuxi's strength could no longer keep up with his speed at this time, and it might even be discovered by the killer. Tian Kong could not do so.

"Yeah." Shuxi lit her little head firmly. At this moment, the confidence in her heart was as solid as a rock. The sky did not abandon herself at any dangerous moment on the way, protecting herself. With such a person by her side, what else can she be afraid of? Never be a burden to him. What can I do now is to use the remaining perception to explore the surrounding situation, and even control the attack and protection of the airflow. But without the support of her body, she doesn't know which step she can do, but she should not make that vase.

After feeling the transformation of Shuxi, the sky relaxed a little, at least she improved a little, so she devoted herself to the unknown danger. She lurked in the dark and searched their killers, and always searched everywhere. And it seemed that no one was alone, which made the sky very depressed. After feeling the transformation of Shuxi, she also relaxed a little, at least she improved a little, so she devoted her energy to the unknown danger. She lurked in the dark and searched their killers, and always searched everywhere. And it seemed that no one was alone, so it made the sky very depressed that she could not touch a single killer, and the sky did not dare to take action easily, and even the ten-star people were not alone. This black dragon really made preparations for this purpose for a long time and stopped making the mistake on the island.

"There are many killers nearby in the sky, but none of them are alone. What should we do?" Shuxi opened his eyes. Although there were many killers around her in her perception, none of them matched the sky's sneak attack hanging. During this period, she also roughly estimated that the number of black dragon killers in this light curtain was already twenty, but none of them solved it.

Even if they can hide like this, there are still time limits. No matter how they drag it on, the sky is limited in energy, whether it is physical strength or energy, and he still has to hold Shuxi, so this state will definitely not last long. If they don’t break the deadlock, they may not be able to get out of here.

"Yeah." After the sky responded simply, there was no following. Now he was more difficult than Shuxi imagined. This town is not as hard as the island. With the dense turn, he could hide his body. But here he could be accidentally bumped into it at any time. Not only did he sense the killers around him, but he also had to fantasize three-dimensional images in his mind, finding the best route and the unknown that he might kill the killers. This naturally increased the physical energy consumption of the sky and also had to bear the weight of one person.
