The green seed is extremely mysterious, and Zhang Yu cannot tell its origin at all. Moreover, its breath is very similar to the original energy, like chaos. This is the first time Zhang Yu has encountered an aura similar to the original energy. The most important thing is that the seed contains extremely terrifying energy, as if it is endless. It is difficult for Zhang Yu to use the means of exerting the will of the world to clearly understand.

This green seed is definitely not something from the Sky Realm. Even the eighth-level true god world may not be able to give birth to such a divine object.

That's right, Zhang Yu is sure that this mysterious green seed is definitely an unknown divine object, with a level that exceeds the eighth level.

"Advanced Insight!" Zhang Yu used the advanced insight technique that he had not used for a long time. This mysterious seed is worthy of his exception to use the advanced insight technique.

However, what shocked Zhang Yu was that the advanced insight technique that was unfavorable had failed this time!

A piece of information emerged in his mind.

Name: Unknown.

Level: Unknown.

Effect: Unknown.

All are unknown!

In the past, when Zhang Yu used advanced insight techniques, he could obtain complete information no matter what he explored. Advanced insight techniques were like encyclopedias, as if there was nothing in the world that it could not detect. Whether it was a person or a thing, as long as Zhang Yu was willing, he could know its basic information. However, this time, advanced insight techniques failed.

This is the first time Zhang Yu has encountered such a situation since he obtained advanced insight!

"This kind of thing is not simple!" Zhang Yu's expression became solemn. Things that cannot be detected by advanced insights are definitely not simple.

He suspected that this kind of seed is probably the most precious thing in the entire sky world. The whole treasure mountain combined is far less valuable than this mysterious seed!

Zhang Yu stared at the mysterious seed for a long time, muttering in confusion: "What the hell is it?"

The Sky Realm was created by the old master of the system. This treasure mountain, including the spiritual medicine, spirit stones, and spirit mines, are all collected by the old master of the system. Therefore, this mysterious seed must have been produced by the old master of the system. However, why did the old master of the system bury this mysterious seed underground? Moreover, this mysterious seed actually has the ability to block perception and explore. If it weren't for this alchemy mistake, the treasure mountain cracked, Zhang Yu would have never been able to discover that there was such a mysterious seed buried under the treasure mountain.

Could it be that this entire treasure mountain is just to hide the existence of mysterious seeds?

No, probably not.

Zhang Yu immediately denied his guess again. If the old master of the system really wants to hide the existence of the mysterious seed, why should he bury it under the treasure mountain? You should know that there are many spiritual ores buried under the treasure mountain. If you dig along the spiritual ore, this mysterious seed will sooner or later be discovered.

If he really wants to hide this mysterious seed, he can find another place that is not eye-catching, such as the underground of the sea or the underground of some ordinary hills.

Wouldn't it be contradictory to bury the mysterious seeds so deep and create a mountain of treasures?

Zhang Yu was a little confused about the thoughts of the old master of the system. He buried the mysterious seeds deep underground. It was impossible for him to plant them? If this is true, then Zhang Yu can only say that the old master of the system might be so funny. If the seeds are buried so deeply, how can they take root and sprout?

"System, aren't you going to say something?" Zhang Yu played with the mysterious seeds and thought communication system.

However, the system seemed to crash at this moment and remained silent.

Zhang Yu had long seen through this system trick, rolled his eyes, and said, "Are you tired of doing this every time you come to this one?"

Seeing that the system had no response, Zhang Yu shook his head helplessly. It seemed that he could not get anything out of the system. Although he was sure that the system must know the origin of this mysterious seed, if the system did not speak, he would have no choice but to deal with the system.

"It seems that this thing is even more powerful than I thought!" Zhang Yu looked at the mysterious seed in his hand. "Apart from the old master of the system, I have never seen the system be so secretive about anything..." Judging from the attitude of the system, this mysterious seed is afraid of hiding an amazing secret, and this secret is definitely related to the old master of the system.

After playing for a while, Zhang Yu buried the mysterious seed in a certain place in the treasure mountain again, and then said to the system: "You can't tell me about this seed, but can you answer another question?"

The system finally made a sound, and it was still a mechanical electronic sound without emotional fluctuations: "What's the problem?"

"Tsk tsk, I'm finally willing to speak!" Zhang Yu laughed. This system was quite willful.

"Host, you have three more breathing time. If you ask a question after more time, the system will refuse to answer." The system's voice did not fluctuate, just like a cold robot, but the content of its speech seemed to have a little emotion.

Zhang Yu coughed lightly, no longer delayed his time, and immediately asked, "Can you tell me if your old master is still alive?" His expression seemed very relaxed, as if he was doing it casually, but his breathing was quietly held, obviously caring about it very much.

"I don't know." The system answered several times after breathing.

"Don't know?" Zhang Yu raised his eyebrows, "Do you still know if your old master is dead?"

"This system really doesn't know." The system said: "This system doesn't know much about the old master, so there is no need to lie to you."

After a pause, the system's voice continued to sound: "I don't know, but I don't know. This system still disdains to lie. If this system doesn't want to say it, just reject you directly. This system has not done such a thing, so why should I lie?"

The corners of Zhang Yu's mouth twitched slightly. This system really doesn't give him face.

However, he had to admit that the system made sense and he was rejected by the system less than once or twice. If the system really didn't want to say it, it would be enough to directly refuse the answer, and there was no need to lie to him.

"So... you don't even know if your old master is dead?" Zhang Yu curled his lips and said contemptuously: "Your system is so bad, and you don't even know if your old master is dead..." After finally seizing the opportunity, Zhang Yu did his best to mock the system, or constantly test the system's attitude and bottom line.

The system stopped saying a word, as if it had disappeared.

It's its usual routine again!

If you don’t want to talk, just pretend to be dead!

Zhang Yu felt like he was punching a cotton, and he felt bored.

After looking around, Zhang Yu sighed and flew into the sky, and began to repair it one by one from above the treasure mountain.

Although space has the ability to repair itself, the power of the fifth thunder of the Mercedes Dragon Pill is too strong, and the damage to the space is beyond imagination. It also leaves a trace of energy, which leads to the speed of space repair becoming extremely slow. There is no way, so Zhang Yu could only take the initiative to repair these space cracks by himself.

There are too many secrets hidden in the sky world that cannot be destroyed for the time being!

With Zhang Yu's addition, the speed of repair of the Sky Realm was accelerated by more than ten times. The cracks that stretched thousands of miles were recovered at a speed visible to the naked eye. The energy left over from the thunder of the catastrophe was also constantly cleaned and erased by Zhang Yu.

Nearly a month later, Zhang Yu looked at the repair of one-third of the Sky Realm, and his eyes twitched slightly: "Sure enough, construction is much more difficult than destruction..." The thunder took only a few breaths to make the Sky Realm riddled with holes and almost collapsed. It took Zhang Yu nearly a month to repair one-third.

Seeing that the January period agreed with Bai Ling had arrived, Zhang Yu stopped the work at hand, and a twisted and dark space vortex appeared out of thin air in front of him. He took a step and stepped into the space vortex in one step, and his figure disappeared.

The next moment, his figure appeared in Doupo World.

With a sweep of his divine thoughts, he instantly found Xiao Yan, Wu Mo and his group.

The figure stayed in the void for a moment, then disappeared again. When it appeared again, it had already arrived in the primeval forest where Xiao Yan and his group were.

At this time, Bai Ling and Bai Jie were standing on the edge of the cliff, one was constantly demonstrating illusions and giving serious guidance, while the other was listening carefully, like a dry sponge, absorbing nutrients frantically. The illusions were improving almost every moment. Unfortunately, even though she had worked very hard, for the past month, she had even been squeezing all the rest time, and was completely used to understand illusions. Even the time of cultivation was spent on illusions, but she still did not reach the six-star illusionist.

"But this is normal... If she really reaches six stars, it will be strange." Zhang Yu thought.

He was not disappointed. After all, Bai Ling's illusion has already reached five stars. It is normal to spend hundreds or thousands of years from five stars to six stars. Even if Bai Lingru's poems are very extraordinary today, almost no less than Bai Jie. Even with Bai Jie's unreserved guidance and giving them all, it is difficult to improve the level of illusion by one level in a month.

The higher the level, the slower the improvement speed. Those seven-star professions can often take millions of years or even longer to make a little progress.

Although it is far less difficult than the seven-star to eight-star, it is not easy to improve by just having a simple understanding.

Zhang Yu slowly approached, watching Bai Ling's mind exploring the illusion without distraction, immersed in the ocean of illusion, and was quite satisfied. Although Bai Ling's illusion level had not been improved, Zhang Yu was very satisfied with Bai Ling's persistence, hard work and diligence. He opened his mouth and prepared to cough lightly to remind Bai Jie and Bai Ling that he had arrived.

However, he had time to speak, but suddenly the mechanical electronic sound of the system sounded in his mind: "Congratulations to the host for completing the task..."

At the same time, Bai Ling seemed to have a clear understanding of the secrets in an instant. The illusion that was originally slightly flowing on the surface suddenly became realistic. In front of her, a beautiful wild chrysanthemum was swaying in the breeze, and the air was even filled with a fragrance, which was almost no different from the real flower. No matter from any aspect, it seemed like a real wild chrysanthemum, not an illusion.

Zhang Yu stopped and looked at Bai Ling in shock: "A miracle really happened?"

At the last moment of the agreement, Bai Ling was actually promoted to the six-star illusionist by chance, as if she was deliberately waiting for him here. It was so coincidental that it was hard to believe.

At this time, Bai Ling opened her eyes, and a bright smile appeared on her beautiful face, and her voice was a little excited: "Old ancestor, I succeeded! I did not disappoint the director's expectations!" Perhaps the latter is the reason why she worked so hard and even created miracles.
Chapter completed!
