Although Fengyun discovered the flaws in the force field, he didn't immediately do it. He needs to simulate in his mind and adjust each step to the best state, so as to avoid any problems, especially not to waste time.

To break through the force field in less than a tenth of a second and pass through it, with Fengyun's skill, it also seems very nervous.

Let alone set aside a reserve to restore the force field, otherwise problems will still occur when the light passes by.

This puts forward more stringent requirements on Fengyun, because the more reserved, the better.

Taking a deep breath, Feng Yun began to adjust his state, mainly to improve his body's functions and put it in a critical state, trying to save him time.

After about two minutes, Feng Yun's eyes suddenly lit up, and then the knife was pulled out by him, and he cut towards the force field ahead.

The afterimage of the blade cutting through the force field was still there, and Feng Yun had already left the place and appeared in the force field.

Feng Yun succeeded, but he did not relax, instead, he turned around as fast as he could and looked at the force field, especially where he used it to cut.

He needs to confirm whether there will be any problems when passing through the place. Only if there are no problems, will he be done, otherwise he must choose to evacuate the Stone City in the first place.

"Call!"

What Feng Yun saw made him secretly relieved.

The force field's recovery speed was much faster than Fengyun expected. When the light passed the place where he cut by the knife, the cut by it had recovered as before, and the light passed by without any problems.

Even so, Feng Yun still didn't relax his vigilance, and he didn't even try to open the closed room immediately. He wanted to check again.

Although the force field he himself saw didn't have any problems, it didn't mean that its creator, that is, the cannibals would not be aware of it. Maybe his actions have attracted the attention of the cannibals.

If he concentrates on opening the closed room at this time, he might be surrounded by the cannibal barbarians. By then, it will be difficult for him to escape.

It is not convenient for him to activate the combination of the eyes of the snake **** and perception, but he has raised his hearing to the limit. As long as there is some movement, he will catch it.

The stone city is still quiet.

Unreasonably, he looked around again. Feng Yun turned around and came to the front of the enclosed room. Before he started his hands, he once again activated the combination of the snake god's eyes and perception to observe.

At the beginning, he also controlled their power. He worried that there was a force field hidden on the house, which would touch it.

As a result, his mood improved a bit.

The enclosed room is only protected by the first layer of force, which is the floor through which Fengyun passes.

He still didn't try to open the room, but to enhance the power of the combination of the eyes of the snake **** and perception. He planned to use them to get a general understanding of the situation in the room.

Although they don't have the ability for him to have perspective, but because of some characteristics of the snake god's eyes, he can see thermal imaging according to the temperature.

In other words, if there are cannibals in the room, it is possible to know their number and location through thermal imaging, which is undoubtedly very helpful to him.

Soon, the combination of the eyes of the snake **** and perception was raised to the limit by Fengyun, but the effect was not able to satisfy him.

Although he didn't see anything, he could only confirm that there were many cannibal barbarians in the room. As for the specific number of them and their respective locations, he could not tell.

Perhaps because the building materials of this enclosed house are quite special, the effect of the combination of snake eyes and perception is greatly compromised, and thermal imaging is simply blurred.

Of course, being able to confirm the existence of cannibal barbarians in the room, and knowing that there are a lot of them, is already a big gain for Fengyun, which is enough for him to change his strategy.

His first choice was to get to know the situation inside the house through the door, and now he is going to go to the back of the room.

In fact, his best choice was to go to the roof, but he was worried that he would be discovered by the cannibals in the city.

Although the house he chose is far away from the other enclosed rooms, it also has a problem, that is, there is no good shelter. If he goes on the roof, it will become easy to be found.

When he got to the back of the room, Feng Yun used the combination of the eyes of the snake **** and perception to observe it again. He chose a location relatively far away from the cannibal barbarian. He stuck out the index finger of his right hand and gently pressed it against the wall. Above the surface.

A faint brilliance came out from the fingertips, it was the intent of a knife, and a hole appeared in the wall immediately, and there was no sound in the whole process.

The hole Fengyun made in the wall was so small that he couldn't even put a toothpick in it.

However, Feng Yun still nodded, seemingly satisfied.

In fact, with it, don't look at it, he can see some of the room's situation clearly.

Feng Yun did not move his eyes, but once again used the combination of the eyes of the snake **** and perception to observe and meditation in the room. He worried that the small hole he drilled in the wall had been discovered by the cannibal barbarian in the room. But pretending not to know, when his eyes moved closer, he suddenly launched a sneak attack, inflicting heavy damage on his eyes.

Thermal imaging has not changed.

Feng Yun was relieved, and stopped waiting, and moved his eyes together.

Without the occlusion of the wall, Feng Yun could easily see the situation in the room. Although limited by the angle of view, the range he could see was not large.

But just what he saw, also changed his expression, and the expression of surprise appeared in his eyes.

Before seeing the cannibal barbarians in the room, Feng Yun had already had many speculations about their status, but the actual situation was not any one of his guesses.

They all closed their eyes, sat there, motionless, with both hands grasping a pillar with the thickness of an arm, and grasping it very firmly, the pillar was nearly transparent.

Therefore, Fengyun could see that a ray of brilliance was extracted from the pillar, and the cannibal barbarian who was caught by the pillar absorbed it into the body.

During this process, Feng Yun could feel that the aura of the cannibal barbarians had increased, and their strength was improving.

Although the extent of the improvement is not very large, that is, Fengyun feels very keen, and most people can't even notice it, it still has a big impact on Fengyun.

Although he doesn't know much about the cannibals, this does not prevent him from confirming that their strength at this time has improved far beyond the normal level.
