The person Gu Tingchen sent out came back quickly with a reply.

"Mr. Gu, we followed those two people and found that they entered the cabin of a broken ship near the dock and never came out again." This is what the two people reported to Gu Tingchen.

Gu Tingchen couldn't help but be curious, and frowned in surprise, "Never came out again? What does that mean?"

"We watched them go into that shabby cabin, but we waited for several hours and they didn't come out. We wanted to report to you as soon as possible, so we came here directly to tell you without tracking them in the cabin."

Gu Tingchen pondered for a moment after hearing this, then smiled complacently. He seemed to have discovered something and praised his men, saying, "You did a great job. It was right not to go in. If you had gone in, you would have died."

The two men had no idea how serious the situation was. They looked at each other in surprise and were so frightened that they couldn't utter a word.

"Okay, you guys go down and rest." Gu Tingchen didn't even think about explaining to them. He waved his hand and sent them away.

Even though the two men didn't understand, they didn't dare to ask any further questions and could only lower their heads and retreat.

Gu Tingchen guessed that the cabin of the broken ship must lead to somewhere, most likely the house that could only be entered but not exited. He was ready to take the risk and try it himself, but before that, he had to take measures to protect himself.

The next night, Gu Tingchen gathered all his men around the broken cabin. He equipped them with radio communication equipment and wore it in their ears. As long as Gu Tingchen was in danger, he only needed to say a word and they would all move out together.

After arranging everything, Gu Tingchen walked straight into the broken cabin.

It was indeed very difficult when we first entered. It was damp and dilapidated, as if it was about to rot and collapse. Gu Tingchen felt like he could hardly breathe, so he had to cover his nose and continue moving forward.

But after passing through the first door, the scene took a 180-degree turn.

What appeared before Gu Tingchen's eyes was a wide and clean passage with snow-white tiles and a snow-white ceiling, leading straight to a mysterious distance. The passage had no end in sight, but the lights here were voice-controlled.

Gu Tingchen made a little noise every few steps to turn on the lights, but not enough to attract other people's attention.

In this way, Gu Tingchen walked deeper and deeper, and the further he went inside, the more he realized that this passage was not simple, because it was built underwater, and building such a passage in the sea water requires considerable financial resources.

After walking for an unknown amount of time, Gu Tingchen arrived at another door. He gently pushed the door handle and found that the door could not be opened.

"Damn it." Gu Tingchen cursed softly. The answer was right in front of him, but he just couldn't touch it.

However, at this moment, there was a rustling sound coming from the other side of the door. Gu Tingchen thought it was not good and knew that someone was coming. He wanted to find a place to hide immediately, but the passage was straight and there was no place to hide!

Gu Tingchen took out the dagger he carried with him, intending to take the person inside hostage as soon as he opened the door.

He gritted his teeth and decided to take a gamble.

By the time the person inside grabbed the door handle, Gu Tingchen was already ready to attack, just waiting for the other person to open the door so that he could put the knife to his neck!

It's time!

The door opened from the inside with a whoosh. A man was about to go out, but was grabbed by Gu Tingchen. After he was pulled out, a knife was immediately put to his neck.

The man was so frightened that he immediately raised his hands in surrender, then asked with his legs shaking, "Who? Who?"

"Stop talking nonsense! I'm asking you, how do you open this door?!" Gu Tingchen pressed the knife hard against the man's neck, indicating that if he refused to tell the truth, his neck would be cut!

The man was so frightened that he trembled all over and stammered, "Brother, brother, I'm telling you, please don't do anything."

It was at this time that Gu Tingchen discovered that this man had actually come out to dispose of the body, because when he just raised his hands to surrender, Gu Tingchen happened to see a human-shaped object sliding down his back.

Now, the dead man was lying inside the door, and Gu Tingchen was standing outside the door holding the man hostage.

Gu Tingchen knew that once this door was closed, he would not be able to open it again. Someone inside had to tell him how to open and close the door freely.

Fortunately, the person Gu Tingchen kidnapped was a complete coward who was afraid of death.

"This door needs a fingerprint to unlock it." The man said hesitantly with shaking hands.

Gu Tingchen frowned in displeasure upon hearing this, thinking that this person was lying to him, so he tightened his knife even more forcefully, "You'd better tell the truth, or I'll kill you right now. You said it was unlocked with fingerprints, but where is the fingerprint recognition?"

Gu Tingchen searched the door for a long time but couldn't find any place to identify fingerprints.

"No, no, I really don't dare to lie to you. In fact, this whole door is a fingerprint recognition device. No matter where you touch, the system can recognize it." The man's face turned pale with fear, and he didn't look like he was telling a lie.

But Gu Tingchen still didn't quite believe it, so he ordered, "Use your fingers to open the door for me and see!"

The man did as he was told. His hand simply touched the door handle like a normal person would open a door, and the door indeed opened.

Gu Tingchen smiled smugly, nodded with satisfaction and said, "Okay, in that case, you stay here. If my people want to come in, you will be responsible for opening the door for them. Otherwise, don't blame me for being rude."

The man didn't dare to raise any objection and just kept nodding at Gu Tingchen.

"There is progress. Everyone, come into the cabin and go to the passage to help me watch a man." Gu Tingchen immediately spoke into the radio, signaling everyone to come in and watch the man.

Let everyone in, firstly to protect themselves, secondly to prevent the men from escaping, and thirdly so that if anything happens, these people can use the men's fingerprints to unlock the door and rush in.

After everyone arrived, Gu Tingchen used the man's fingerprint lock to walk in.

The scene suddenly became quiet. Gu Tingchen saw that after passing through the second door, the scene in front of him changed again.

This is a large living room, but the layout and furnishings are no different from those of an ordinary home. After Gu Tingchen entered, he immediately began to look around, trying to let his eyes take in more information.

"Are you looking for me?"

At this moment, a very cold voice sounded from somewhere.
