Seeing Nie Tian's serious face, Si Huahong and Shi Feng quickly led others to follow him.

When everyone came to the safety passage on the third floor, Si Huahong asked in confusion: "Nie Tian, ​​my men have already searched here just now, but they didn't see Lan Lan?"

"Mr. Si, look at this door lock."

Nie Tian walked to the safety door, held the broken door lock and said, "This door lock was not cut off with a tool, but was broken off with a strong technique."

Si Huahong, Sun Han and his men were stunned.

Who in the world can break such a thick door lock with brute force alone?

They didn't believe it, and neither did Shi Feng: "Nie Tian, ​​I admire your skill very much, but I'm afraid you made a wrong judgment this time."

"You may not believe it, but I still maintain my opinion. A top expert has been here."

Nie Tian said as he walked through the security door and motioned for everyone to continue following him.

After entering the safe passage behind the door, Nie Tian pointed to the elevator at the end of the passage.

"Mr. Si, do your men think this elevator is the same as the elevators in shopping malls, so they didn't check it specifically?"

Si Huahong glanced at Sun Han, who immediately nodded, indicating that Nie Tian was right.

He just personally led a team to inspect this place and found nothing unusual about the elevator.

"If I hadn't seen the door lock being broken by someone, I would have thought it was an ordinary elevator."

Nie Tian continued to express his guess.

"Now I suspect that the top expert forced the safety door open, so his next behavior is either to enter here and leave, or to check the elevator."

After hearing what Nie Tian said, Shi Feng was the first to walk to the elevator door and didn't see anything unusual in the elevator.

But when he pressed the door open button and walked into the elevator, he was stunned on the spot.
