"In other words, you know a lot about underground buildings, right?" Xiaolan fanned the air in front of her in disgust, and then asked.

David smiled slightly, his eyes naturally narrowed, "It's not just understanding, it's just knowing everything." ”

He turned around and pointed to the ground, "This location, if I'm not mistaken, is the commanding height of the building below. ”

"Shouldn't the vantage point be a chimney?" Ellie wondered.

"You're right, but in comparison, this is the highest point." David said as he put his hand on a handful of black dirt in front of him.

After flattening, he drew a rectangle on it and clicked twice in one of the corners, "This is the location of the chimney, which should be under your cemetery." ”

Ellie nodded affirmatively, and after Davy got the feedback, he pointed his finger to the other end of the symmetry, "This position is where we are now." ”

With that, he drew two lines on the top of the rectangle, "This is the chimney, and here is an attic-like shape protruding from the outside of the castle. The young man you are talking about, and Rifle, must have gone down to the castle from this hole. ”

Wang Sensen waited for him to finish speaking, then flashed behind him, tightened his trouser legs, and was about to burrow into the hole.

"Don't worry, we should discuss it again!" David stretched out his hand and pulled Wang Sensen's waistband and said solemnly.

Wang Sensen looked back, didn't speak, shook off his hand, and hid in the hole.

Ellie saw that he was all in, and hurriedly looked at the big guy, "Let's be idle too, let's go in." ”

As soon as David heard that she was going down too, he hurriedly stood up, "Ellie, after your father died, I have been busy making ends meet, and I have not found time to visit you. In terms of seniority, you have to call me Uncle Sheng. For your safety, don't go down. ”

"Well, it doesn't matter." Ellie turned around, grabbed the flashlight from the shelf, and walked up to him and said, "I'm a robot now, so I don't have to be afraid of them." ”

-------------------------------------

David stopped Wang Sensen and Ellie, but in the end, no one stopped him.

As soon as he came back to his senses, only him and Xiaolan were left in the basement.

"I'm here to answer them", seeing David's confused expression, he hurriedly changed his words: "Or...... Are you coming to my location? ”

"It's better for you to keep it, although I don't know the situation below, but I still have some understanding of the general structure."

Hearing him say this, Xiaolan stopped talking, and the hand holding the gun slowly raised up, and the muzzle of the gun was not there from beginning to end

Leave the cave for a moment.

David took off his coat, tied his messy hair up, hesitated for a moment, and followed with a flashlight, a wire, and a black suitcase.

Before going in, he turned around and told Xiaolan to find a socket at the other end of the wire and plug it in.

The entrance of the cave gradually extends downward at an angle, and the simple crawling motion can be performed, but it is difficult to turn back once you enter.

As the last person to go out, David had just landed on the ground when he found that they were gone.

Before he could open his mouth to shout, his black hand reached out in front of him, and he reflexively clamped his wrist and twisted it violently.

Immediately after that, a standard domineering over-the-shoulder fall threw the owner of this hand out heavily.

"Damn, you're overreacting!"

David lifted his flashlight and took a look at it, revealing that it was Seven's face, "What are you sneaking your hand out for?" What about them? ”

"I wanted to tell you to be silent!" No. 7 didn't feel any pain, quickly sat up from the ground, looked at the light outside the door and said, "They asked me to stay here, for fear that Li You would escape from here." ”

"Oh, that's right." After listening to his explanation, David also relaxed a lot. Pulling the wire down, he opened the suitcase.

Seven walked over and looked down, "What the hell is this?" ”

"UV lamp, an object from ancient times, at that time, this brand was worth more than 100,000 yuan." David said as he connected the tube and the socket and other accessories.

After neatly installing it with his hands and feet, he let out a long breath and gently pressed the switch.

Suddenly, a deep purple and blue light shone out of the light, filling the entire room in an instant.

He nodded contentedly, then looked around. The truth here is not much different from David's conjecture, and it is not much different from surveying.

Just from the wall structure inside, it can be analyzed.

The wallpaper on the hexagonal wall is full of mold. In some places, you can also see the traces of liquid soaking.

The yellowed marks, under the irradiation of the UV lamp, turned into an earthy brown, and David couldn't help but be shocked when he saw it.

The corners of his eyes twitched slightly, but he was looked at by Seven, "You, did you find something?" ”

"Look over there." David raised his hand and pointed, and Seven looked along.

At first, I didn't understand it, but after thinking about it, I suddenly realized: "Is it bloodstains?" ”

"That's right, it's blood."

"But how do you know?" Seven turned around and looked at him with the eyes of an interrogator.

David sighed again and again: "After the company declared bankruptcy, I went to join the army. After I was discharged from the army, I changed jobs several times and opened a private detective agency with a friend. ”

"Oh." Thinking that he was also half a peer, Seven also relaxed his vigilance.

At this moment, a series of footsteps came from the corridor outside the door.

"Uncle David, you're here," Ellie said, then turned back to say something to the people behind her, and walked in.

Looking at the UV lamp he was holding in his hand, Ellie nodded, "It seems that it still works." ”

"Well, did you find anything?" With that, David handed her the lamp in his hand.

Ellie took it in her hand and said without raising her head, "The position of the hall on the first floor has collapsed. ”

"Maybe it's caused by digging up above, I saw those excavators when I came just now."

Ellie sighed, her thumb picking at the lampshade, "No other traces of excavation have been found for the time being, Li You and Uncle Laifu are probably still here." ”

"Then be careful, I should be the most familiar with this place. Tell them to come back, this time for me to lead the team. ”

-------------------------------------

Judging from David's statement, the structure of this building may be more complicated than Ellie's house.

This is often the case with buildings that mix a variety of construction methods. Most of the reasons for this design are for aesthetics, and if it is for practical purposes, there is no need to go to such great lengths.

After listening to Ellie's introduction to the owner of this house, David also had a number in his heart.

"According to you, that monster was still alive when you escaped, right?" David asked.

"Well, that's how it should be."

Wang Sensen stood at the door, still thinking about what this "sloppy king" was, and when he heard him ask, he suddenly had a flash of inspiration and came to Ellie's side.

"Where is it?"

Ellie, who didn't know why he was so excited, briefly explained the general direction and asked him if he had thought of anything.

"In this case, Li You and Laifu should go to find the mother. That monster is most likely the mother. ”

Thinking of this, he asked Ellie where he could quickly get down to the dungeon.

"If that's the case, we'll have to go back and go through the chimney in the cemetery."

Hearing this, David smiled slightly, "No need, in such a magnificent building, there is definitely more than one passage to the dungeon." ”
