Neither of these two speculations can be proved, and Ye Chu could only look for clues little by little in the experiment.

He actually did not notice any signs of life in the Void Cave Heaven, but if that creature is higher than their rank, and not to mention its strength, it would be easy to avoid being discovered.

For this reason, Ye Chu decided to take a different approach, look for a slightly smaller high-level creature, and go to the Void Cave Heaven to test it.

This high-level creature is preferably a plant system, and has the same origin as the plant system in the Void Cave Heaven. In this way, it can survive in the Void Cave Heaven to achieve the purpose of investigation.

If anyone knows Ye Chu’s plan, he may be shocked and his chin falls off. What is the concept of cultivating a high-level creature? It is basically equivalent to creating a god. Even in a small world, creating a god is not so easy to do.

According to the concept of immortal cultivators, the gods and immortals that are often called are actually more powerful humans, but the high-level gods that Ye Chu mentioned are different. They are born with the world they were born with, and are the core of the world and the law of controlling the world.

It’s another story whether it’s powerful or not, but this level is definitely unquestionable.

On the other hand, Ye Chu did not know that the spiritual herb he cleaned out had now become a life-saving straw for everyone in the shelter. It can be said that this shelter has not yet been broken, and the support of herbs definitely accounts for the majority.

Of course, Dabai's contribution is also a great contribution. Without it, Ye Chu would be too lazy to send it to Fang Da and his men. If Fang Da and the others didn't come to get it, Ye Chu would think it would not be necessary.

In the eyes of Fang Da and others, this fairy grass is so precious that they are not so shameless and have been asking for it.

Dabai has now become the second only to Ye Chu in Fang Da's heart. He went to the battlefield to kill... How many monsters he ate are second. Although this guy killed more monsters than anyone else, it can be said that he killed like a beast, but what is more important is the supply of fairy grass. Once Dabai is not there, this battle will be no suspense.

No matter what, humans persevered, and the tide of monsters finally slowly retreated late at night after the thirteenth day, as silent as when they came.

After confirming that the tide of monsters has completely receded, everyone's first reaction was not to cheer or be glad, but to fall asleep. They were almost at the point where they were exhausted and could not hold on.

After falling asleep in the entire shelter, Ye Chu walked out of the courtyard. He seemed to feel the end of the monster tide. He came to the sky above the shelter and spoke in one direction: "What is the result of the trial?"

"If you don't have you, you will probably die here." Kuwu's body slowly appeared, his expression a little strange, "Where do you get so many immortal grass spirit fruits? Although the grade is not high, this number is terrifying enough."

"I planted it myself." Ye Chu replied casually, "But you were wrong. If they weren't my fairy grass, they wouldn't be so motivated. They had already run away when they saw that the situation was wrong. Would they still wait for the monsters to kill?"

"That's true, but that result is not very satisfactory." Kuwu pinched his chin and checked the information from the Maze Center. The amount of information revealed was so large that it was enough to shock people's chin. "The response of your shelter here is the most satisfactory, because the intensity of the monsters attacked here was adjusted by me, which was more than twice that of other shelters. The other few lost a lot less than before because of Bai Ze's intervention, but they were far less than that of this one."

"The parameters of this need to be adjusted... the parameters of despair and fear are increased a little, um... twice?" He said to himself, regardless of whether Ye Chu responded or not, "Or what if it is triple?"

"I advise you to be more at ease." Ye Chu suddenly said, "You don't think the result of this shelter is all about pressure, right?"

"Of course there is your fairy grass!" Kuwu replied, "I know this, I will increase the income from killing monsters, such as how to drop the magic crystal core? Or inner alchemy? It seems that many worlds have different names for this, just casually..."

"It's a good direction." Ye Chu nodded, and he took out a jade slip and threw it to Kousu. "This is the information I have collected about the integration of the power system recently. A lot of it has not been verified, so you can judge it yourself."

Kuwu looked surprised. Unexpectedly, Ye Chu actually did this for him, but he still took the jade slip, "You plant grass every day, and you still have time to do this?"

"If you don't want it, forget it." Ye Chu made an attempt to take back the jade slip, but was snatched by Kuwu.

Originally, with a brief attitude, Kuwu Jade Shop's expression became more and more serious: "Potential energy? What does this mean? In addition to all visible energy, there is actually a larger energy hidden, which is potential energy."

Kuwu carefully recorded the contents of the jade slip. This was just Ye Chu's conjecture. It had not been verified, but he was extremely serious. When he reached the word "potential energy", he realized the terribleness of this conjecture.

In the guess, Ye Chu believed that all intelligent lives can sense the existence of potential energy, but the higher the energy of other types in the body, the less likely it is to interact with potential energy. The external manifestations of potential energy in people are usually various emotions, fear, despair, joy, etc.

This is also why the higher the level of immortal cultivators, the less emotions they are, because the more energy they have in their bodies, the less they cannot reach the potential energy. However, the more complex and intense emotions the ordinary people in the world have very little energy in their bodies, and they can better touch the potential energy.

In fact, there are often such things. When an ordinary person faces a desperate situation, he bursts out several times his energy. He has too strong desires occasionally turn into upward energy to help others break through. These are some evidence of the existence of potential energy.

Another aspect is the conversion of potential energy. At the moment when ordinary people can interact with potential energy, if some external force can be applied, the potential energy will be transformed into energy that can be used in daily life, such as immortal power, magic power, Yin power, etc., but the transformed energy will not interact with potential energy. As for the reason, Ye Chu does not know.

Ye Chu's conjecture only completed one prototype and did not conduct in-depth research. However, Kuwu thought this direction was too interesting, and to some extent it coincided with his experiments in the maze, which made him even more excited.

"I plan to leave here. I will leave this research for you. I am grateful for your return to the previous two questions." Ye Chu said, "I have a third question next..."
