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

"Uuuuuuuuuuuuuuuuuu"

Pei Qingniao stared at Tian San with eyes wide open, angry and incredulous, and tried hard to speak, but her jaw had been removed, so she couldn't utter a single word. She could only make a series of meaningless humming sounds to express her anger.

Tian San looked at Pei Qingniao with interest, seeing the anger, humiliation, and a hint of deep fear in her eyes.

"Are you afraid?"

"What are you afraid of?"

"Are you afraid that I'll discover the poison hidden in your dentures?"

Tian San looked at Pei Qingniao with a chuckle, and suddenly said something that made Pei Qingniao tremble all over.

These words were like a bolt from the blue, hitting Pei Qingniao on the head hard. Pei Qingniao's eyes widened instantly and he stood still.

Tian San had already stretched out his hand and pinched Pei Qingniao's chin. Without any movement of his hands, he just gently released his internal energy, lightly shaking Pei Qingniao's teeth.

Of course, the original teeth remained motionless and solid as a rock, but the dentures that were installed later were shaken by the internal force and directly shattered into Tian San's hands.

Tian San held up the denture and looked at it under the light. Through the light, he could clearly see a black area inside the denture, and there was something unknown inside.

Tian San squinted his eyes and looked at the denture. After a moment, he put down his hand, pinched the denture with his fingertips, stared at Pei Qingniao and spoke.

"This is a miniature poison sac that is installed in the denture."

"If you encounter anything unexpected, you only need to bite gently to break the poison sac."

"Once the poison in the sac flows out and is inhaled by you, the extremely toxic effect will take effect in less than three seconds and kill you on the spot. It will be impossible to extract any information from you."

"This kind of thing is usually used on death squads. The purpose is naturally to prevent you from falling into the hands of the enemy and leaking important information under torture."

"If I hadn't seen this stuff a lot before, I wouldn't have thought of it easily."

"If I hadn't removed your jaw just now, I'm afraid you would have bitten your poison sac and committed suicide the moment you saw me get the authority card."

"Now it seems that I acted in time."

Pei Qingniao's face turned completely gray, looking completely bloodless. He looked like an eggplant hit by frost, completely wilted.

But Tian San didn't stop talking, but continued speaking thoughtfully.

"With your status, if you want to enter the underground base, you only need your permission card to come and go as you please."

"The ID card has fallen into our hands. Whether you are dead or alive, we can enter and exit the underground base at will."

"If that's the case, then why do you want to die?"

"With your status, even if you lose the underground base, you probably don't need to commit suicide to apologize, right?"

"But you have a poison sac hidden in your tooth. Why is that?"

"You're not really afraid that Pei Runnian will cause trouble for you if you lose the training base, so you're afraid of committing suicide, right?"

"If you were such a weak coward, Pei Runnian would never have put you in such a dangerous position."

"So, you wanted to commit suicide with the poison sac just now, not because you were afraid that Pei Runnian would cause trouble for you, but because you deliberately chose to commit suicide in order to protect something."

"and many more……"

Tian San seemed to have thought of something, and couldn't help but look up at Pei Qingniao, his brows slightly frowned.

Pei Qingniao, whose hopes had completely disappeared, calmed down at this moment. He looked at Tian San with extremely indifferent eyes, without any fluctuation, and full of deathly expression.

When Tian San saw her like this, he confirmed his guess and said in a cold voice.

"It's obvious that you want to commit suicide, not because you're afraid that Pei Runnian will cause trouble for you."

"Instead, he committed suicide to protect something and prevent us from entering the training base!"

"But we already have your authorization card in our hands. Logically, you can move freely in the underground training base and stay or go as you please. This obviously conflicts with your suicide behavior just now."

"Then the only answer that can explain this contradiction is..."

Tian San paused, his eyes became extremely sharp, and he spoke word by word.

"The things needed to enter the underground base are not only this identity card, but also other things that can prove your identity."

"What is it?"

"Is it the iris, fingerprint, or voiceprint? Could it be the gait?"

Tian San questioned in a sharp tone, and even though Pei Qingniao had already lost all hope, after hearing Tian San's series of sharp questions, he still couldn't help but feel a little palpitated in his heart, and there was a hint of fear in his eyes when he looked at Tian San.

Tian San is such a sharp guy!

I wanted to destroy the permission card, but he discovered me just as I was about to do it and stopped me.

She wanted to bite the poison sac and commit suicide in order to keep the entrance and exit of the underground base secret, but Tian San seemed to have predicted the future. He directly removed her jaw and found all the poison sacs hidden in her dentures!

That’s not all. Based solely on the information that he had installed a poison sac in his dentures, Tian San was able to directly analyze that there was more than one way to enter and exit the underground base.

Pei Qingniao committed suicide in order to preserve other ways to enter the underground base, thus making Tiansan's plan fail!

Is this guy still a human?

What kind of enemy did she encounter?

Who are these people?

Pei Qingniao's heart was filled with sadness and despair, and he already had a rough guess about Tian San's origins.

It was precisely because of this speculation that Pei Qingniao's shock reached an even higher level.

Tian San looked at Pei Qingniao, whose eyes were hopeless but who remained silent, as if he had already accepted his fate. He frowned slightly, raised his hand and gently patted Pei Qingniao's chin to restore it, then spoke in a deep voice.

"At this point, all your cards have been exposed by me. Do you still want to resist and say nothing?"

"Besides your clearance card, what else do you need to get into the underground base?"

"I told you I can give you a decent ending."

Pei Qingniao's chin was restored, and he couldn't help but open and close it twice. After he felt it had returned to normal, he raised his head and glanced at Tian San. There was no fluctuation in his eyes, only a dead look, and he still said nothing.

Tian San looked at Pei Qingniao's dead look, his brows furrowed even deeper, and he couldn't help but feel a trace of anger rising in his heart.

"This is your last chance, don't make the mistake."

"Don't forget, your life is still in my hands!"

Tian San's tone had unconsciously become very cold, but Pei Qingniao remained unaware and did not say a word.
