"Instructor!"

Li Chenzhou called out hastily. He still had so many questions he hadn't asked; how could the instructor just run off like that?

"Boss, how did you get to know him?"

Watching the instructor's figure fade from illusion to complete disappearance before his eyes, Duan Lei couldn't help but ask.

"The first time I saw him was in Wu Village!"

Li Chenzhou looked in the direction of Wu Village. They were, after all, in Qing City, not far from Wu Village!

"That time… the night we felt the summons?"

Duan Lei asked.

"Yeah!"

Li Chenzhou nodded.

"That time, the instructor taught me how to fight, gave me that staff, and also let me know about the existence of the Devourers!"

As he spoke, Li Chenzhou looked at the Devourer base. Because of the angle, he couldn't see the pipe below the Devourer base, but Li Chenzhou knew that at this moment, that pipe was still constantly drawing cosmic origin from his world!

Li Chenzhou hadn't seen that thing, but the instructor wouldn't lie to him. Since he said that once the Devourers obtained enough cosmic origin, they would have no chance to defeat them, then Li Chenzhou must stop the Devourers from continuing to absorb cosmic origin!

But the problem was, with that spatial channel constantly providing energy to the Devourer base, Li Chenzhou had no way to destroy this Devourer base, unless…

He remembered that when they got out of the car earlier, the Devourers had opened a channel, seemingly wanting them to enter.

Li Chenzhou didn't go in at the time, because even a fool could guess that nothing good would come of it, and fighting them in the Devourers' lair would definitely put them at a disadvantage.

But now it seemed that the only way to break through this Devourer base was to attack from the inside.

Thinking of this, Li Chenzhou looked at Duan Lei, only to find Duan Lei staring thoughtfully at the spot where Instructor Li Yingning had been standing…

"Right, Instructor!"

A flash of inspiration struck Li Chenzhou.

This time, Li Yingning's appearance didn't involve guiding his fighting or explaining anything; she only talked about the cosmic origin and the rules.

She wouldn't appear after such a long time for no reason, so…

Li Chenzhou looked at the Devourer base. The information the instructor conveyed this time should be twofold: one was that the cosmic origin was very important and could not be taken by the Devourers.

The other was that their current strength was insufficient, but they could try to find loopholes in the rules.

Oh! Right, there was one more thing: they had a rather big trouble, but the instructor didn't explicitly say it, telling them to figure it out themselves. If they couldn't figure it out… they could only be pigs in the future…

Li Chenzhou looked at the Devourer base. Because of the existence of that spatial channel, it was basically impossible to deplete the energy shield of the Devourer base.

So, perhaps he could wait until they had finished absorbing the cosmic origin and were preparing to transport it back before attacking them?

Since the cosmic origin couldn't be transported through the spatial channel, the Devourers could only use aircraft to transport it back to their lair, at which point they would have to leave this location.

But the problem was, first, according to Li Chenzhou's guess, this Devourer base, which was their branch nest, should also be able to fly. So, after they absorbed all the cosmic origin, their entire base might directly ascend.

Although they wouldn't be able to replenish their energy once they left this location, they could completely store enough energy before leaving.

Moreover, it wouldn't take long to travel from the ground to space. Could Li Chenzhou and the others ensure that they could exhaust their energy and destroy their base in such a short time?

Thinking of this, Li Chenzhou couldn't help but shake his head. He couldn't wait until that time, because that would be a gamble. Once the Devourers escaped, the cosmic origin would be sent back, and Li Chenzhou and the others would have no chance to recover.

So, that was just the final plan. Before that, he had to do something.

"Boss, if you were asked to think about the rules of this world, what would be the first thing that comes to your mind?"

Just then, Duan Lei seemed to have thought of something, so he asked.

"The rules of this world?"

Li Chenzhou thought about it. What Duan Lei was asking about must be the rules of this post-apocalyptic world, but did this post-apocalyptic world have any rules?

Perhaps various skills could be considered a kind of rule, but that didn't seem to be of any use to them now. Although the instructor had said before that some skills were simply self-contradictory.

But studying that was of little significance to them, because they couldn't possibly know every Devourer's skills, study the loopholes in their skills, and then try to target them. That would be too much trouble.

"World level?"

Li Chenzhou replied.

Aside from skills, the only rule Li Chenzhou could think of was world level, and that was also what he was most concerned about now, because he still hadn't figured out whether the Devourers' level was three or five.

Although many Devourers had been shooting at them from the Devourer base before, Li Chenzhou was hiding in the car at the time and didn't sense their levels at all.

"Right! World level!"

Duan Lei nodded.

"I suddenly remembered that, according to the people of the Duoluo world, the world level is calculated according to the highest life form in this world. So… do the ones in the small world count as being in our world?"

"Huh?"

Li Chenzhou was stunned. The small world in the castle was an independent, special space, so it shouldn't belong to this world.

In other words… if Grey Bear was in the Duoluo world and didn't affect the world level of this world, then raising the level in the small world shouldn't affect this world either.

However, that didn't seem to be of much use, because they could only hide in the small world. Once they came out, it would immediately affect the world level of this world, and fighting the Devourers would definitely be in this world…

Wait!

Li Chenzhou suddenly looked at Duan Lei.

"You… are you thinking about the suppression of world level?"

"Yes!"

Duan Lei nodded and said, "Since our world has the suppression of world level, and the level of foreign creatures cannot exceed the highest level of life in this world, then… why can't the small world have this kind of rule suppression?

This small world is ours, so can we also formulate some rules that are unique to this small world, and then pull the Devourers into the small world to fight them?"

"Formulate the rules of the small world? Is that… possible?"

Duan Lei's words stunned Li Chenzhou. He originally thought that Duan Lei just wanted to use the small world to raise everyone's level, and then find an opportunity to raid the Devourers, catching them off guard, but he didn't expect that this guy was thinking about formulating the rules of the small world…
