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

It would be fine if they just used gait detection devices, but they also had to add permission cards, iris testing, and blood DNA testing!

Such a complicated detection procedure almost blocks the possibility of outsiders trying to sneak into the underground base.

Even if someone, like Qin Tianshuang and Tian San before, was lucky enough to obtain one of the methods to pass the test, but faced with the other three detection methods, if they were not prepared in advance, they would still be at a loss. The final result would be that the test failed, and the invasion was discovered by the people in the underground base, and the two of them ended up fleeing in panic.

Unless you have gathered all the ways to pass the detection, it is impossible to sneak in quietly by disguising yourself.

But it is extremely difficult to collect all four methods.

In this way, the defense of this underground base is considered to be impregnable and cannot be invaded by outsiders at all.

Qin Tianshuang was just thankful at this moment that she and Tian San were cautious after getting Pei Qingniao's authority card and did not act rashly.

Otherwise, their identities would have been discovered and they would be besieged by the guards of the underground base!

While feeling thankful, Qin Tianshuang suddenly felt extremely curious.

If this underground base is just an ordinary training base, there seems to be no need to set up such a complicated and abnormal identity verification method.

After all, although the training base is important, it can only be regarded as a reserve base for cultivating fresh blood. For the Pei family, it is not the core interest.

Even if the training base was attacked, it would only be a loss of face, and the loss to the Pei family's strength would be minimal.

However, the Pei family set up such a complicated and abnormal identity authentication method in such a training base, and they have worked hard to protect the security of this base.

But the problem is coming.

How can a training base that does not involve the core interests of the Pei family be qualified to enjoy such a high level of security protection?

Qin Tianshuang's pupils suddenly shrank, but then immediately returned to normal, but the emotions in his heart could not be calmed down so easily.

There is only one answer.

That is, this training base is not just an ordinary training base in their eyes. It is very likely that there are other secrets hidden in this base.

And those hidden secrets are the reason why the Pei family attaches so much importance to this training base and protects it with such high-level security measures!

"This is interesting. I just wanted to embarrass the Pei family, but I didn't expect there would be an unexpected surprise."

"What secrets does the Pei family hide in this base?"

A strong curiosity arose in Qin Tianshuang's heart, but at the same time his vigilance was also raised to the highest level.

Since there are such deep secrets hidden in the training base, and the Pei family has set up such a complicated identity verification method to ensure the reliability of people entering and leaving, it is conceivable that the Pei family must have hidden more forces here to protect this base.

There might not only be more than a thousand people in this base as stated in the intelligence they collected, but there might be far more than this number!

Entering the base is already so complicated, you can imagine how strict the security inside the base is.

In this way, the difficulty for Qin Tianshuang to take the opportunity to paralyze the ventilation system after sneaking in has soared to the highest level. The risk of his identity being exposed has also increased, and he may very likely encounter other unknown dangers.

This underground base has completely become a dangerous den of dragons and tigers. Once you enter it, you may face unpredictable dangers at any time.

But Qin Tianshuang only thought for three seconds before deciding to continue sneaking in according to the original plan.

If you don't enter the tiger's lair, you won the tiger.

If the plan to attack the training base is to succeed, sneaking into the base and destroying the ventilation system is the most critical step.

If she didn't go in, they would not be able to destroy the base as originally planned, and Chu Longtu would not be able to achieve his goal of slapping the Pei family in the face.

If the Pei family could be effectively deterred and their deterrence and influence could be broken in front of everyone in Hedong, then the dinner party held by Chu Longtu would really become a joke.

So no matter what, she must completely destroy this training base!

What's more, Qin Tianshuang himself was very interested in the secrets hidden in the training base.

She really wanted to go in and see with her own eyes what the Pei family had hidden in this training base. Maybe there would be some unexpected surprises.

While Qin Tianshuang was still quickly thinking about modifying the infiltration plan, Pei Qingniao, who had already passed the identity verification and entered the gate, looked back and stretched out his hand to quickly tap on the gate a few times.

After hearing a few beeping sounds, I saw the metal floor and the flashing light on the metal arm of the gait detection device suddenly disappear.

"I've turned off the gait detection device, but you only have fifteen seconds. Come quickly."

"If you remain in the device before the gait detection device restarts, then you will have to wait for Gatlin to give you a bath."

As soon as Pei Qingniao said this, everyone started running like a bull that had been kicked in the butt, rushing through the gait detection device at the speed of a 100-meter sprint.

Qin Tianshuang was carried by two bodyguards as she rushed through the gait detection device. When she just passed, half of the bodyguards who were carrying her were still on the gait detection device.

"drop!"

Suddenly, a sharp beeping sound was heard, and the gait detection device suddenly lit up with a rich blood red color like fresh blood!

The next second, twenty-four holes suddenly appeared on the seemingly smooth and empty walls on both sides, and twenty-four pitch-black gun muzzles popped out from the holes, firing directly without any pause!

"Bang bang bang bang!"

Fierce gunfire instantly flooded the air, and countless bullets whizzed out like a downpour, instantly submerging the entire gait detection device.

The bodyguard, who was half a body behind, felt his scalp explode instantly. He used all his strength to take the last step and left the gait detection device.

The barrage of bullets, like a torrential rain, whizzed past the bodyguard's shoes and hit the ground and the wall heavily.

Pei Qingniao was quick-eyed and quick-handed. After the last bodyguard entered the door, he almost simultaneously punched a red button on the wall.

There was a loud bang, and the door popped open instantly and closed with force, blocking all the bullets outside the door.

However, even through the heavy door, everyone could vaguely hear the crackling sound coming from behind the door, like firecrackers. It was the countless stray bullets hitting the door, making the noise.

If Pei Qingniao had been a step later, those countless stray bullets would have poured down on them and completely destroyed them!
