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

When Qin Tianshuang saw the remaining three strong men obediently make way, even though she had already expected this in her heart, she was still a little shocked.

She never expected that the trump card Chu Longtu gave her before she left was so useful. Qin Tianshuang thought Chu Longtu was fooling her!

The so-called trump card that Chu Longtu gave to Qin Tianshuang was the black powder with a strange fragrance that she had just touched on her body.

When Qin Tianshuang was about to leave the villa, Chu Longtu personally handed this thing to her and told Qin Tianshuang to use it at the most critical moment.

"This substance can confuse the mind and make the opponent work for you, but the drug effect is very strong. Once the opponent is infected, the entire brain will begin to be irreversibly damaged, and the opponent will walk, sit or lie down like a zombie."

"So once this thing is used, the enemy will soon discover the abnormality, so we must not delay and must fight quickly before the enemy notices."

"If we are discovered by the other party and fail to escape in time, we will be in big trouble."

Chu Longtu's words seemed to ring in his ears again, but at that time Qin Tianshuang thought that Chu Longtu was exaggerating the effect of the medicine. At most, it was like smoke that could confuse others for a while. How could it make the other party obey his words?

What they practice is martial arts, not immortality, okay?

Qin Tianshuang was skeptical about the efficacy of the black powder, so she did not put all her hopes on the black powder, but decided to give it a try on her own.

I used it just now because I didn't want to alert the enemy, so I had to treat it as a last resort and give it a try.

But Qin Tianshuang never expected that Chu Longtu did not exaggerate the efficacy of the black powder at all.

When this stuff is rubbed on the body, it can actually confuse other people's minds and make them become like puppets who obey your orders!

From the moment the bald burly man was attacked, his every move was completely in line with Qin Tianshuang's words, without even a hint of objection, which made Qin Tianshuang feel both surprised and scared.

The surprise was naturally because the black powder was so effective. After controlling the flat-headed burly man, he could naturally and easily blend into Area 0 to see what secrets were hidden inside.

What is frightening is naturally that the effect of the black powder is so overbearing that just by smelling it, it can completely control other people's minds.

Qin Tianshuang prided himself on being a knowledgeable person. He had once worked in the executive department of Tianluodiwang, where he had been through wind and rain, traveled to countless places around the world, killed countless people, and seen many scenes and shocking existences that were beyond the imagination of ordinary people.

However, this was the first time she had seen something as excessive as black powder, and she was so shocked by its strange and overbearing medicinal effect that her heart was beating wildly.

Even Qin Tianshuang himself couldn't help but complain in his heart, wondering how could Chu Longtu be so confident in handing such a horrible thing to him so directly.

There wasn't even any packaging. Wasn't Chu Longtu afraid that Qin Tianshuang would inhale the smell of the black powder, and thus suffer as well, being poisoned by the black powder and turned into an idiot?

But even though she complained, Qin Tianshuang knew clearly that Chu Longtu had given her a powerful weapon.

With this thing, it is no exaggeration to say that from now on there will be no secret base in this world that Qin Tianshuang cannot sneak into!

Because no matter how heavily guarded a base is, its operation still depends on people to maintain it!

The black powder in Qin Tianshuang's hand is the most effective in dealing with people!

So in this world, the most successful infiltration is actually never the one that quietly breaks through all the opponent's security defense measures and sneaks into the local base alone.

In fact, the most successful infiltration is to bribe the enemy directly, open the door and get yourself in. It not only saves time and effort, but also has no risk at all. It is simply perfect!

Qin Tianshuang's mind was filled with all sorts of messy thoughts, but in reality it was only a matter of a moment.

So when the remaining three strong men made way for the door, Qin Tianshuang had already followed the flat-headed strong man and walked towards the door.

When they reached the gate of Area 0, the burly man with a flat head walked straight forward and placed his big hand on the gate.

A bright blue light suddenly lit up above the originally pitch-black gate, and a green light fell from the top of the gate, sweeping across the flat-headed burly man's face.

There was a ding sound, and the door suddenly turned green, and an emotionless mechanical synthesized sound rang out.

"Fingerprint verification passed, please take blood test."

As soon as he finished speaking, he heard a slight click and a metal platform suddenly popped out from the wall next to the door.

In the middle of the platform was a thumb-shaped mold, and the burly man with a flat head pressed his right thumb on it.

The next second, a hissing sound was heard.

Three seconds later, the mechanical synthesized sound sounded again.

"Blood verification passed, please verify iris."

The sturdy man raised his thumb, and Qin Tianshuang saw a needle as thin as an ox hair in the center of the mold slowly retracted, and a tiny drop of blood slowly seeped out of the thumb of the flat-headed sturdy man.

Then with a hissing sound, the mold sank and disappeared, and then a light screen rose up, flashing the same faint blue light.

The burly man with a flat head turned his head and leaned over, staring at the light screen with wide eyes.

The same green light swept across the eyes, and with a ding, the light screen also turned green, and the mechanical synthesized sound sounded again.

"Iris verification passed."

"All verifications have passed, the door is open."

"After clearing out."

The burly man with a flat head took a step back, and Qin Tianshuang also quickly followed suit, marveling at the strict verification methods of Area 0.

Qin Tianshuang was walking in the underground base just now. Basically, all areas were undefended or had very little defense. There was no such strict security measures.

If there were such strict security measures everywhere, then Qin Tianshuang would not even be able to leave the place where she was just now!

Not to mention anything else, the defensive measure of taking blood to verify DNA alone can make all of Qin Tianshuang's superb disguise methods ineffective.

After all, you can make the face look exactly the same, but you can't change the blood.

Even if you want to make a blood bag and tie it on your finger to get by, don't forget that you have to verify your fingerprint before drawing blood.

During that verification process, the blood bag will be completely exposed.

This trinity of strict defense measures is only slightly less stringent than the verification methods used when entering an underground base, including the gait detection system.

This made Qin Tianshuang even more curious about the secrets in Area 0!
