Disciple, please come down the mountain soon. Your senior sister can’t wait any longer.

When Pei Xingchen's trusted subordinate gave the order, the companion who had just received his message had already quickly come to an independent office beside the hall.

The office is filled with densely packed equipment, and there is a large display screen hanging on the wall, showing the scenes of dozens of underground bases. It is obvious that this is a monitoring center that can monitor the situation in various parts of the underground base in real time.

The man walked quickly to the central command seat facing the big screen, which was a seat reserved for the director of the underground base, Pei Xingchen.

In the past, when Pei Xingchen stood here, he could see all the images on the big screen very intuitively, and he could also see the work status of everyone in the office.

In addition, a separate computer is installed on the command desk, which makes it convenient for Pei Xingchen to issue orders at any time.

After walking quickly to the command seat, he pressed a single red button on the command seat table without any hesitation.

After the button was pressed, there was a hissing sound, and a square flat plate on the left side of the command seat began to sink silently, and then a black button covered by a translucent cover rose up.

There is also a tiny mechanical lock on the cover made of transparent high-strength material, which locks the black button inside.

If the mechanical lock is not opened, the black button inside cannot be touched at all.

The man took out a tiny key, inserted it into the mechanical lock and turned it gently. With a click, the mechanical lock was opened and the cover automatically popped up, revealing the covered black button.

Without any hesitation, the man smashed his fist hard on the black button.

"Drip drip!"

An extremely sharp alarm sounded throughout the base in an instant, and a mechanical and indifferent voice sounded instantly.

"Warning, the base's ultimate defense system has been activated. Everyone please follow the emergency plan and rush to the designated location to assemble immediately, otherwise you may be accidentally injured!"

……

The same warning sounded three times in a row, and when the warning sounded, there was a commotion in the hall.

The apprentices who had never experienced such a scene suddenly became a little timid and quickly turned their heads to look around.

Tian San, Tian Qi and Qin Tianshuang were looking at Pei Xingchen intently. Tian San narrowed his eyes slightly and spoke slowly, seemingly gentle but actually cold.

"It seems that the lesson I just gave you was not enough. You actually dared to attack us."

"But it just so happens that I was also very upset when I let you run away just now. Since you have the same idea, let's fight again and see who can get the final victory."

Pei Xingchen's face was also full of coldness and cruelty.

"I won't make the same mistake twice."

"So, the ultimate loser will never be me."

"You can start praying for your sad fate now."

Amid Pei Xingchen's brutal threats, three warnings were also sounded.

Then the beeping alarm sounded sharper and sharper, and drastic changes began to take place in the entire underground base.

Including the hall where Tian San and his companions were, heavy metal doors suddenly fell down at the entrances of all the corridors in the entire underground base, instantly blocking and closing all the passages. The entire underground base was instantly divided from its original unobstructed state into one enclosed space after another.

At the entrance of the hall, a thick metal wall was also lowered, blocking the passages leading to other directions in the hall.

And on the walls of the hall, small holes appeared one after another with the same hissing sound, and protruding from the small holes were black gun muzzles, indiscriminately aiming at everyone present.

At the same time, there were also low hydraulic drive sounds on the ceiling. The original metal ceiling quickly moved away, revealing something hidden behind the ceiling.

There were tiny nozzles one after another. Normally, those tiny nozzles would spray out clean water to extinguish flames.

But once the ultimate defense system is turned on, those tiny nozzles can spray out poisonous gas that can easily kill a person.

Depending on the scale of the enemy's invasion, the poison gas can be divided into two types: anesthetic gas and lethal gas.

But no matter which one it is, it will be a big trouble for the invading enemies, enough to make their scalps tingle.

At that time, as soon as the gas is sprayed, the heavy metal door will block the exit. In this confined space, the invading enemies will be completely helpless and can only face their own doomsday in despair.

However, according to Pei Xingchen and his team's idea, if there really was an invasion by foreign enemies, they only needed to retreat to a safe area and watch the enemy being tortured to death in the enclosed space.

But now Pei Xingchen and the others are trapped in the hall together with Tian San. If the lethal gas is really sprayed out, they will not be able to escape either.

So when Tian San and the others saw the sprinkler head above their heads, their faces changed for a moment, but after thinking it over they were not too worried.

Tian San looked at Pei Xingchen and nodded slowly.

"It seems like you really want to fight us to the death."

"But now you and we are all in this enclosed space. Even if you can use the nozzle above your head to spray poison gas to kill us all, do you really have the courage to die with us?"

"No, you don't. You don't have the guts."

Tian San shook his head, Tian Qi raised his eyebrows and spoke jokingly.

"If he had the courage, he wouldn't have looked like that when we caught him just now."

"I bet a dime that he would never dare to do that."

Qin Tianshuang also took over the conversation and said with a smile.

"If you open the market, I'm afraid no one will bet against you."

"Anyone with a discerning eye can see that he doesn't have the guts to do that. Only a fool would bet on a game that they know they will lose."

The three of them acted like they were performing a crosstalk, singing in unison and making fun of Pei Xingchen as if he were a fool, not taking him seriously at all.

Pei Xingchen's face became increasingly gloomy, and the murderous intent in his eyes became increasingly fierce.

However, his trusted subordinates were startled, and seeing that Pei Xingchen's face looked wrong, they started cursing.

"fart!"

"You guys deserve to die. As Master Pei's daughter, why would I want to gamble my life with you?"

"Now that the ultimate defense system has been activated, it can easily beat you into a sieve. Instead of kneeling down and begging for mercy, you are provoking me. Are you really tired of living?"
