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

Qin Tianshuang glanced covertly at the wall behind the gait detection device.

She could bet a dollar that there were machine guns or other weapons hidden behind these seemingly normal walls.

Once the gait detection device detects a problem, those hidden weapons will definitely pop out immediately and instantly kill the intruder who cannot pass the gait detection device, leaving him absolutely no chance to defend himself.

The existence of these weapons has invisibly added tremendous psychological pressure on the invaders.

Even if there are people who can successfully simulate the gait of others with unparalleled talent, in a test where not a single step can be wrong, as a wrong step will result in instant death, can they withstand the pressure of life and death, pass the gait detection device without making any mistakes, and successfully enter the door?

impossible.

Under such strong and suffocating pressure, no one can avoid making mistakes.

Camouflage cannot pass the gait detection device, and if you want to truly pass the gait detection device, there is only one way left.

That is to sneak into the database that stores gait detection data, and replace the gait data of the disguised target with your own gait data, so that you can naturally pass the gait detection successfully.

However, the difficulty of sneaking into the database of gait detection data is probably more difficult than Qin Tianshuang paralyzing the ventilation system of the underground base. It is a nearly impossible task.

Therefore, the combination of these factors makes this gait detection device reliable, and can even eliminate the possibility of intrusion to some extent.

Qin Tianshuang couldn't help but feel fortunate in her heart that she and Tian San did not easily invade the underground base after getting Pei Qingniao's ID card.

Otherwise, even if you can enter the underground base with an authorization card, you will still be blocked by the gait detection device.

Once the people who are monitoring the place from behind find out that they have Pei Qingniao's face but cannot pass the gait detection, they will immediately think that someone is disguising himself to sneak in, which will directly lead to the failure of the infiltration mission.

It’s okay that the mission failed, Qin Tianshuang has failed before.

However, once the secret of her infiltration is discovered, the Pei family will definitely be more strict with identity verification after learning this lesson, making it so difficult for Qin Tianshuang to infiltrate, or even impossible for her to infiltrate. That would be troublesome.

Fortunately, they were able to hold their ground and find another way, coming here as Fang Zhiming's men, giving Qin Tianshuang a real chance to sneak into the underground base.

Just as Qin Tianshuang was secretly rejoicing, Pei Qingniao also shook off the support of the bodyguards, let them stand where they were, and he slowly took steps onto the metal floor of the gait detection device.

Only she can walk this road, because only her gait data has been entered into the database, and the bodyguards around her have not entered the access rights to this road.

If Pei Qingniao lets the bodyguards support her as she walks through the gait detection device, the device will then directly detect the gait data that has not been recorded by the bodyguards, and will directly determine it as an outsider intrusion. After triggering the alarm, the weapon will be ejected directly and the person will be shot indiscriminately.

In order to avoid this tragic scene, even though Pei Qingniao was still very weak, he could only try his best to support his body and pass through this passage.

When Pei Qingniao just stood on the metal floor, the originally dull and matte metal floor and the pitch-black metal arm suddenly buzzed with a sound, as if they were suddenly turned on. A light blue light suddenly lit up on the black floor and the metal arm, circulating like water, illuminating the entire passage in light blue.

A mechanical voice suddenly sounded.

"Gait detection device activated, proceed through now."

"Warning, if your gait data has not been entered into the database, please exit the test immediately."

"If you do not withdraw, you will bear all the consequences yourself."

The mechanical sound sounded an alarm, but Pei Qingniao seemed not to hear it. He slowly raised his legs and stepped onto the metal floor that had turned light blue. Although each step was slow, he still began to move forward firmly.

The light blue lights on the metal arms on both sides of the road suddenly rose and fell like the tide, illuminating the entire space in light blue, which looked quite bizarre.

The people standing outside the passage watched Pei Qingniao pass through the gait detection device step by step with great difficulty. Their hearts were in their throats and they were sweating.

It would be really funny if Pei Qingniao happened to fall or stumble.

However, the worst result that everyone imagined did not come true. Although Pei Qingniao walked slowly, he walked steadily until he walked out of the coverage of the metal arm. The flashing blue light on the metal arm did not turn into the red light that made everyone panic.

That extremely mechanical voice sounded again.

"Gait detection passed, now please confirm your identity."

A small LCD screen suddenly popped up on the gate standing at the center of the gait detection device. Pei Qingniao took out his authority card and swiped it on the LCD screen. After a beep, a mechanical sound was heard.

"Authorization card test passed, please test iris."

A green box popped up on the LCD screen, and a red horizontal line was scanning from top to bottom.

Pei Qingniao lowered his head slightly and moved his right eye closer. He heard a beeping sound again, and a green check mark popped up in the green box. The mechanical sound sounded again.

"Iris scan passed, now please verify DNA."

Then the edge of the LCD screen automatically shrank back, and a thumb-sized metal space popped up again.

Pei Qingniao raised his right index finger and gently pressed it on the metal space. There was a thin, transparent, hollow needle tip in the center of the metal space. It easily pierced Pei Qingniao's fingertips. A drop of bright red blood was gently sucked into the needle tip and flowed downwards.

Just three seconds later, the mechanical voice sounded again.

"The DNA test has passed."

"All tests passed, identity verification successful."

"Pei Qingniao, welcome back."

When the mechanical sound fell, the door that had been tightly closed suddenly made a bang, and then slowly moved and gradually opened, revealing a dark passage.

Immediately, a cold air rushed out along the passage and blew on everyone, making them shiver uncontrollably.

Qin Tianshuang, who had watched Pei Qingniao verify his identity throughout the process, was not only glad that he had not sneaked in without permission, but he almost couldn't help but want to curse.

These people from the Pei family are too perverted.
