In fact, the group crept behind Davy and arrived on the first floor in a short time.

According to Ellie's description of the underground structure, he walked straight to a house. Standing at the door, he hesitated for a long time before gently pushing the door open.

The creaky door jammed a third of the way open. David walked in on one side, shining his flashlight everywhere, and after making sure there was no danger, he told them all to follow.

The size of the room is small, no more than ten square meters at most. In the corners of the wall stood several sticks, which were still worn in several places.

"This is supposed to be a utility room, these ...... It may have been a mop before death. David said, holding the sticks in his arms and letting the man at the door hand them out.

After clearing the ground a little, he stared at the floor drain with both eyes and said without raising his head, "Ellie, you just said that there is a wading position at the bottom, right?" ”

"Hmm."

"After that area, you pass through a regular passage and it tends to be uphill. And, there are huge pipes overhead. ”

Suddenly realizing what David was going to say next, she frowned and asked, "You don't want to get into the sewers, do you?" ”

"I think your little head is better than your father," David smiled back at her, and continued, "yes, let's go in through the sewers." ”

Wang Sensen pouted at No. 7 and jumped out and said, "Otherwise, let's go around the distance and go down from the cemetery." ”

"The wires aren't long enough, and a lot of time is wasted in between."

"That's right", No. 7 didn't pay attention to Wang Sensen, and took two steps forward and said: "We can't be sure yet, whether Li You and the missing Laifu are looking for the so-called mother, and if there is any accident during the period, it will be over." ”

Ellie also agreed with his statement, and while looking at Wang Sensen, she said, "Except for Li You, you know the danger of this infection best, what do you think of their current state?" ”

was first ignored by No. 7, and then questioned by Ellie, Wang Sensen's melancholy expression was comparable to Tony Leung.

"Actually, I have less contact with it. Moreover, it is the first time that I have seen it in the process of transformation. However, I heard Li You say before that this infection is very fast, and if it completely transforms into that kind of thing, it is basically hopeless. ”

As soon as he spoke, everyone fell silent. Each has different calculations in their hearts, David is worried that Li You will hurt Ellie, Ellie is worried that Laifu will suffer misfortune, only No. 7 is thinking, without Li You, the case can still be solved.

This continued for nearly five minutes, with Wang Sensen taking the lead to break the deadlock.

He turned around and picked up the mop stick that had been placed at the door, stood in front of the floor drain for a long time, and stabbed it hard.

"Click!"

The stick snapped at the waist, and David looked up at him and said, "This drain is made of pig iron, don't tell me you want to use the stick to get it fast." ”

As he spoke, he walked towards the door, and was nowhere to be seen in a short time.

Several people watched him blankly as they walked away, each with a blank expression. When I started, I didn't think about it so much. When Wang Sensen mentioned that it might not be reversed, he felt extremely uncomfortable.

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

"Ellie, you said that this house was designed by several designers, why is this pipe so ...... How simple is that? ”

Seven asked, holding the crowbar David had taken from above, as he looked at the open floor drain, and a foul smell wafted from it.

"Because the casting process was limited at that time, the cost of complex pipes was too high, and it was enough to be practical." Ellie, covering her mouth and nose, replied.

With the joint efforts of everyone, a big hole was finally dug out of the ground. At the lower end of the pit is the entrance to the sewer.

Davy grunted and threw down his shovel and wiped his sweat, "It smells too bad down there, and Ellie said that this pipe probably passed through the lab, and there might be something in there." ”

"Then you all stay on it, and I'll go down by myself." After Seven, he held the edge of the pipe with his hand, and before he could poke his head in, he was pulled by David.

"You're ...... So on? He didn't know that Seven's body was eighty percent machine, and he didn't let go of his hand until Ellie explained.

"Be careful! We'll go down from the cemetery and we'll see you later. After Ellie finished speaking, Wang Sensen also handed him the UV lamp.

also told him that if he saw Li You, he must not be soft, as long as he did not kill him.

In everyone's worried eyes, Seven didn't say anything, just nodded and drilled down.

During the entire crawling process, Seven was thinking about Li You, and as soon as his attention was distracted, he didn't care about the smell around him.

"Rift, ripp...... Where? ”

It's been a quarter of an hour, and it's a fairly spacious pipe, and it's not very difficult to climb up. Only the first part of the steep part is a little uncomfortable, and the rest is basically flat.

After climbing around a Z-corner, Seven stopped and shook his flashlight twice inside, but still didn't see the rift that Ellie and David were talking about.

Just when he was a little impatient, suddenly a series of strange voices came from directly in front of him.

The high-pitched and piercing sound is like a person being pinched by the neck, and no matter what the situation is to listen to, it will not feel comfortable.

Seven had thought there was only sewage and a stench, but at most two rats were popping up. But the reality slapped him mercilessly.

Now I want to go back, it's basically no fun. Not to mention the positions in the middle that are almost straight up and down, just the Z-shaped bend that you have just passed, people with poor body flexibility can't pass through.

Moving forward, there are unknown dangers; Falling backwards, the difficulty factor is high.

In a dilemma, he punched the pipe wall, gritted his teeth and glared, stuffed the flashlight into his mouth, and crawled forward heroically.

It's just that the speed is much slower than before. Fear was just one thing, and he did it to give himself enough time to react.

After climbing for a while, the piercing sound became closer and closer, and the pipe, which was still stable, began to tremble up and down with the movements of Seven.

"There may be a rift ahead." Thinking of this, he cheered up again and looked intently ahead.

I kept praying in my heart for the arrival of the rift, and the size of the rift was best to let myself get out smoothly.

God seemed to hear his plea, and just as his patience was reaching its limit, the rift appeared before his eyes.

At the same time, the origin of the unknown noise that had plagued him for a long time was also revealed.

A rat about the size of a magic bucket was at the edge of the rift, rubbing its beard with two paws.
