There was no door in this room, there was only one exit, which was the staircase, but Yu Beiming didn't dare to go, he wasn't sure if the Archbishop was still watching him outside.

If he found out that those illusions were useless to him, Yu Beiming didn't dare to guarantee whether he could survive the other party's next means.

As for what the archbishop said before, he said that he would leave something, didn't he see that he said to Yu Beiming before that he wouldn't do anything to him?

This person's words, Yu Beiming doesn't believe a word now.

Since there is no door, Yu Beiming is ready to make a passage exit by himself.

Yu Beiming found a position to determine the perspective that could avoid the staircase, and then stretched out his hand, and the Xuan Ting Knife appeared from the space equipment.

He didn't know that the archbishop was gone, and in this case, he subconsciously chose what he thought was the safest method.

With the knife in hand, Yu Beiming's eyes were also much more ruthless, and he was not slow to start, holding the handle of the knife with both hands, slashing vertically, slashing horizontally, all on the wall, with a burst of sparks flashing, Yu Beiming only felt that the wall was extremely hard, and the Xuanting knife, which was originally sharpened like clay, slashed on it, and the pollution did not react.

Yu Beiming observed the place he had cut before, and there was really no trace.

"One more life. ”

Yu Beiming didn't believe in evil, so this time he hit his attention and slashed out with all his strength again.

This knife is different from before, using the ability of thunder and lightning control, and with the power of the Thunder Knife Technique, the power has directly increased more than several times, Yu Beiming still doesn't believe it, it doesn't work this time.

"Huh~~?" Yu Beiming was dumbfounded.

He had just slashed at the wall, and it was supposed that even a diamond would leave a few holes, but the wall didn't react.

Oh no, there was still a slight scratch and scorched mark, but in a second, it was back to its original appearance.

"Damn, this archbishop is really polite enough to me!" Yu Beiming laughed angrily, but the hand holding the knife trembled a little.

But he didn't know that it was not only because of the credit of the wall, but also because of the formation that he wanted to teach the archbishop to release before.

That array can not only activate the murals on the wall, allowing them to bewitch Yu Beiming, but also absorb the aura of heaven and earth, and fill the aura into the walls made of special materials.

This wall was originally a spiritual treasure for the archbishop, and it has an incredible ability, not only to trap people, but also to have the ability to recover automatically.

As long as the aura is sufficient, it can even last forever without changing.

Yu Beiming is troubled at this moment, but he is not a person who admits defeat easily, and he will not give up because of just two failures.

If you don't seize the opportunity to run away now, when the archbishop returns, you really won't be able to run.

"Alas, it's a pity that the sound transmission feather note I sent out was discovered by the archbishop who wanted to teach, and with his means, it is estimated that the sound transmission feather note was intercepted, and there is no signal here, and I can't even make a phone call, so it seems that I can only rely on myself. ”

Yu Beiming was a little frustrated, but he quickly reworked his spirit.

Because he was afraid that there might be an archbishop outside, he didn't dare to use the moves with a large range and a lot of noise, and the rest of the moves were the most powerful in the previous thunder and lightning control plus the Thunder Knife Technique.

However, Yu Beiming didn't mind adding some more material.

"The Thunder Emperor is furious. He let out a low roar, first there was a pain in his body, and he could clearly feel the tearing sensation in the muscles and veins in his body, and before Yu Beiming could grin, his body was shaken with spiritual power, and his momentum became even stronger.

Although he had already used this trick a few hours ago, it stands to reason that he should rest for a little more time before using it again, otherwise there would be some damage, but these damages are much insignificant compared to falling into the hands of the Desire Sect.

Yu Beiming didn't mind getting some injuries in order to escape.

"Again~~come~~!"

The Xuanting knife danced again, turning into a wall of knives, and when it slashed at the wall in front of him, thunder and sparks appeared at the same time, but fortunately, Yu Beiming has always controlled the angle of the chop, otherwise the sound of the impact can be transmitted dozens of meters away.

However, after dozens of knives in a row, Yu Beiming also felt a little tired, but looking at the wall in front of him, although there was a deep trace, it was now recovering at an extremely fast speed.

In order not to let his previous efforts go to waste, Yu Beiming continued to use the knife and slashed in the same direction again.

I don't know if it's because my movement is really small, or what the reason is, what makes Yu Beiming happy is that the archbishop of the Desire Sect didn't suddenly appear to catch him.

But the joy soon faded, and the wall in front of Guy was too difficult to manipulate.

Yu Beiming originally thought that he only needed to use brute force to get through, but now he understands that this idea is too simple.

The wall wasn't the thickness he thought it was at all, and it took him seven or eight minutes, and he was running out of strength, and he hadn't seen his head yet.

On the contrary, the recovery speed of the wall is getting faster and faster, but he is now almost out of strength.

"I'm afraid this is a little difficult!" Yu Beiming was so uncomfortable that he wanted to cover his forehead.

Especially when the visions in front of him were still flickering, and he thought that the archbishop didn't know when he would return, his mood was even worse.

This time, Yu Beiming's previous calmness was also somewhat broken, and in desperation, he tried to put a system card on the wall, ground, and ceiling:

[Fortified Fortress: A medium-grade spiritual treasure, which can be attached to any building, making all sides of the building an impregnable fortress, and also has the effect of absorbing spiritual power and automatically recovering. 】

"I'll see if there's any flaws. Yu Beiming continued to look down, he firmly believed that nothing was perfect, and sure enough, let him find:

[The only flaw of the fortified fortress is that it cannot be pierced, once there is complete damage anywhere, then the fortified fortress will be completely ineffective, which is equivalent to abandonment. 】

"System, what does this explanation mean by 'complete damage anywhere'?"

[Like punching a hole through it or something.] 】

"Punch a hole?" Yu Beiming pinched his chin and kept thinking: "Make a complete hole for him?"

"I have no choice but to try this trick. ”

Yu Beiming also knew that he didn't have much physical strength now, and the "Thunder Emperor Fu" didn't have much time, so he simply came up with a whim and came up with a strange trick.

He held the Xuanting Knife lightly in his hand, and then used thunder and lightning to control this natural skill, simulating the spiritual power into the appearance of an electric drill, and the Xuanting Knife is the central pillar of the electric drill, and the tip of the knife is the drill bit, with the movement of his mind, the electric drill began to rotate rapidly.

Rumble!!

Yu Beiming pushed his hand forward, and the "electric drill" began to drill forward, and the sharp tip of the Xuanting knife continued to push the wall forward at a speed that was many times faster than before.

"Really?"

Yu Beiming's face was filled with joy, he didn't expect that this method, which was just a temporary idea, could really work.
