Instead of returning to his alchemy laboratory, Zheng Shu first went back to the bedroom to wash in the bathroom after a long absence, so that he no longer looked like a beggar.

Although using the Dragon King's material conversion power can also directly clean up the dirt on his body, Zheng Shu still feels that it is refreshing to wash it with water.

"Huh? You're back? ”

When Zheng Shu just wiped his head and walked out of the bathroom, he happened to meet Chu Zihang who came back.

As early as more than two months ago, Chu Tianjiao passed various tests of Kassel Academy, although he will still be monitored to a certain extent in daily life, but at least he can live a normal life, so Chu Zihang no longer runs for his father, but returns to the dormitory again.

It's a pity that Zheng Shu was obsessed with making bone vials at that time and couldn't extricate himself, so the two of them still couldn't see each other often.

"That's right, the principal just assigned me a task to go to my hometown and recruit the old road."

Hearing this, Chu Zihang's eyes lit up, and although there was no expression on his face, he could also feel his happiness.

"Lu Mingfei is also coming to school? That's great. ”

Zheng Shu glanced at Chu Zihang's expression that was still paralyzed, and felt that the child was hopeless, obviously his father's emotional fluctuations became violent after he came back, but his face still didn't have too many expressions as before, and now he was afraid that he was not born with facial paralysis.

"It's good, it's good, but when he comes, there won't be less trouble, the principal said that this kid's bloodline is S-level."

"That's going to be a lot of trouble."

Chu Zihang's eyes narrowed, he had been mixed in Kassel Academy for almost a year, of course he knew what kind of temperament this group of half-breeds was.

Although he doesn't know why Lu Mingfei was evaluated as an S-level half-blood, according to his understanding of Lu Mingfei, let alone S-level, the other party cannot reach the minimum limit of ordinary half-breeds in all aspects except for appearance.

As soon as such a person enters a place like Kassel Academy, the half-bloods will surround him like hungry sharks.

Chu Zihang no longer spoke, but sat on his bed, closing his eyes and thinking about how to help Lu Mingfei tide over the difficulties after he entered the school. Zheng Shu glanced at Chu Zihang, silently put on his clothes and left the bedroom.

Back in his alchemy laboratory, Zheng Shu planned to clean up this place a little, after all, it was really a bit impossible to see people.

When he came to the side of a pile of discarded ore, he snapped his fingers, and the pile of ore automatically cracked, revealing the bone flask inside.

At a cursory glance, there were at least a hundred of them in this pile of bone flasks. This is because Zheng Shu has been researching other things during this time, and he has not paid much attention to it after studying how to make the highest quality bone flasks.

Aiming at this pile of "resurrection coins" and opening his hand, Zheng Shu's mind continued to move along a certain established "password". After waiting for two or three seconds, a golden portal appeared on the pile of bone vials, sucking them up.

This is what Zheng Shu researched during this time - the Nibelungen that can be carried with him.

Truth be told, it cost him half his life to make this thing. The Nibelungen is worthy of being called the pinnacle of alchemy, and even with the control of the full body dragon king, Zheng Shu is still tortured to death.

The most uncomfortable thing is that if something like the Nibelungen wants to take shape, the amount of material that needs to be consumed is there, and even if it can be made, tens of billions of tons of matter will be consumed to create enough dead elements.

Fortunately, Zheng Shu has the help of instant noodles and the power of material transformation, which can create a large amount of matter infinitely, otherwise he simply does not have enough funds to conduct experiments.

After creating the Nibelungen, Zheng Shu fell into the trouble of how to miniaturize it.

After several attempts, he found that the Nibelungen dissipated quickly as soon as its overall mass was as small as a certain limit.

After all kinds of attempts, he finally found a solution that could barely be regarded as a solution, which Zheng Shu called - Rushing Out.

As the name suggests, the exit of the Nibelungen is carried around in a certain way, so that although the Nibelungen body is fixed in its original position, the exit can cross time and space.

However, the disadvantage of this is that because the position of the exit is not stable enough, the matter of the Nebelengen will continue to dissipate, and Zheng Shu can only maintain it by constantly adding new material elements to it.

Fortunately, for Zheng Shu, who has panel skills, this kind of thing that can kill others is just a gesture for him.

And after solving these problems, he has a super giant space that can store living things.

When he was finally able to use the Nibelungen's portal to access items at will, Zheng Shu burst into tears. It's not easy, after more than 20 years of traveling to this world, he finally obtained most of the protagonist's theoretical novice equipment - space rings.

After collecting most of the bone flasks, Zheng Shu looked at the last bone flask that was deliberately left, and reached out and pressed it on the floor of the laboratory.

With the fluctuation of his thoughts, a golden portal also appeared on the ground of the laboratory, and he threw the bone vial into it, and Zheng Shu closed the portal and completely cut off its opening path.

This was a defective product he made when he tried to make the Nibelungen, because the structure was not complete and the balance of the elements was skewed, causing the overall quality of the Nibelungen to dissipate.

After Zheng Shu's calculations, this thing will probably reach the critical point of disappearing in a hundred years. Although it is a defective product, Zheng Shu now uses it as a hidden place to store bone flasks.

After he was busy with all this, the sky was unconsciously dark, Zheng Shu patted the dust on his hands, walked out of the alchemy laboratory and looked at the dark sky outside, and suddenly found that he seemed to be idle for a while.

said that he wanted to prepare the enrollment plan the day after tomorrow, but Zheng Shu felt that he didn't seem to have anything to prepare, and he would basically be done by going to Professor Guderian's side to report tomorrow, and there would be no accidents on Lu Mingfei's side...... Probably.

Recalling Lu Mingze, who had been behind the scenes in the original book, Zheng Shu scratched his head with some uncertainty. With his current state of existence, it was not impossible for the little demon to fight him desperately if he suddenly went crazy.

After all, in the original book, before the old thief in Jiangnan ate the book, the little devil shouted something every day, "The day I return to the world, all the rebels should die" and something like that, if he discovers the essence of Hela, he will protrude from the spiritual world on the spot to settle accounts with him.

Sitting on the lawn by the lake, Zheng Shu was suddenly stunned when he was thinking about these messy things in his mind, and he saw a strange and familiar figure in the dark.

Thank you for the tips from the readers of the old hunter who passed by, and thank you for your support.
