"It's just a dead person, I've faced death many times in the past few days, it's a little indifferent!" Gao Xiang's attitude was still very insistent, and he grabbed the large terrifying scar on his neck with his hand.

"Say it again! If Hina wants to," Yan Shen Shi chuckled, trying not to say his words to death.

Why is this guy suddenly interested in the sewers! It can't be like that Spencer, for something valuable! Greed doesn't end well!

"I can take the place of Captain Yan or Mr. Ahab, promised..."

"You're talking too much!" Yan Shenshi interrupted Gao Xiang's words and reminded, "How to arrange, I have my own measure!" ”

The corners of Gao Xiang's mouth rose and he closed his mouth.

In the room of the dissection room, Chen Xunyi and Ren Mingxiao put on protective clothing, and he carried a metal box on his back.

"Why bring dissection tools?"

Chen Xunyi tidied up his neckline and sleeves, and put the protective mask in the outer pocket of the protective suit, "Maybe there's something in it that allows us to perform dissecting operations!" ”

"What? Isn't dissection surgery for mutated organisms? ”

He walked over to the glass shelf and took the empty glass and put it in his pocket, "I have a hunch that this bacterium might be some kind of mutated creature!" ”

"Why do you judge that?" Ren Mingxiao opened the satchel and filled it with some sun-dried fern grass.

"In fact, the ammonia nitrogen level of the sewer samples has been at a high level in the past few months, but the increase is quite obvious in the past few days, in addition to the excrement, the most likely situation is that the corpse is decomposed, and after the flea area has a case, it is usually not going to the hospital, so the corpse is disposed of in the sewer, and the sudden increase in the death of this case will make the ammonia nitrogen in the sewer sample increase sharply."

"You really make sense when you say that!" Ren Mingxiao put the protective mask in his pocket, "Are we going to wait here, or are we going to the combat headquarters?" ”

Chen Xunyi's head skimmed outward, "Waiting outside, wearing this outfit, it's not comfortable to be inside!" ”

"So what are we going to do after we find out the cause of the water quality problem?"

"Before we go to the sewers, we have to ask the city government to cut off the water supply and find a new source of water supply! Otherwise, more and more people will die in the flea area! ”

"I'm not optimistic that the city government will do that!" Ren Mingxiao shook her head.

"If Mr. Mayor doesn't want to be ousted by the angry populace, he'd better do it!"

Lao Zhong walked in, "Doctor Chen, Captain Yan is already outside, he is waiting for you in the car!" ”

"Okay!" Chen Xunyi raised his hand to signal that he knew, and he pointed to the door of the room with his thumb, "Let's go!" The sewers in the area of the Wanghe River in the north. ”

After getting into the car, Ahab was already sitting in the back seat, wearing a medical gown.

Yan Shenshi sat in the co-pilot seat and pointed back, "The trunk of the car, there is a miner's hat, and the kind with a lamp on it, you can hold the flashlight without one hand, so it is convenient to use both hands." ”

"Good!" Chen Xunyi patted his knee, and he found that Gao Xiang was wearing a protective suit, while Yan Shenshi was not wearing a protective suit! "Captain Yan won't go down with me?"

"Let Gao Xiang follow you! I have to be outside, in case something happens to the Great Wall of the Border, I can get there. ”

"Doesn't the defense of the Great Wall of the Border belong to the Defense Forces?"

"Although we belong to the defense team, we are also a member of the guard force, so we are also responsible for defending the Great Wall of the border!"

"If so! Then I just want Ahab to go down with us alone! ”

"Not alone!" Ahab said, "Only then can two people take care of each other and protect you!" ”

But apart from the two of you, no one else believes it! Chen Xunyi frowned, if Captain Yan didn't go over, then find another opportunity to talk about the things in the guard troops!

"Don't be so unconfident in people? Dr. Chan! Gao Xiang grabbed the steering wheel and said in a pitiful tone, "Although I am not as strong as Captain Yan in all aspects, I will definitely do my best to protect your safety." ”

"Uh... But it's dangerous! ”

"I know!"

Chen Xunyi couldn't find any reason to refuse Gao Xiang for the time being, he could only smile reluctantly and secretly accept this result.

The location of the Extinct City is in the middle of the border Great Wall, because the foundation of the Great Wall blocks the flow of surface water, so as long as the rain lasts for a long time, the water level of the Wanghe River will skyrocket, threatening the internal buildings of the city.

Later, the city began to build a large sewer on a large scale to drain the necessary urban floods, and soon the sewers greatly slowed down the flooding caused by the rain.

There are a total of eight entrances to the sewer, which are evenly distributed in the extinct city, and after entering the sewer, the whole system is like multiple pipes built together, extending in all directions, and the ground is about ten meters high from the top floor! The width is three or four meters.

The car stopped at the entrance to the sewer, and at the end of the street, a dilapidated wooden house came into view, the wooden door above which was particularly old, dusty, and green and mildew.

It was drizzling in the sky, making the already dull air more and more depressing, Chen Xunyi took off his glasses, rubbed his eyes vigorously, and the four people wearing protective clothing stood together, took the miner's hat, and brought it up.

Yan Shenshi handed the wireless communicator to Chen Xunyi, "If there is any situation, notify us immediately, don't delay it too long, this thing will run out of power!" ”

"Okay!" Chen Xunyi put the wireless communicator in his pocket, and he walked towards the wooden plank room, and Ren Mingxiao followed.

Ahab and Gao Xiang followed him with pistols.

Chen Xunyi put his hand on the handle of the wooden door, he could smell a sour and rotten smell from the wooden door, the wooden door was gently opened, the inside was gloomy and dim, through a little light outside, you could see the floor inside the room, inlaid with a wooden plank, on which there was a handle with chains.

Yan Shenshi took the flashlight outside, shining the light of the flashlight on the wooden board, "Open the wooden board, and it is the steps to the sewer." ”

He walked in and handed over a drawing wrapped in his pocket in the room, "This is the drawing of the sewer, bring it, the situation here is quite complicated, you must put it away, otherwise you won't find the exit!" ”

"Okay!" Chen Xunyi received the drawings into his inner pocket, he grabbed the chains, and slowly pulled up the wooden plank, the dust flew quickly in the light, and the steps were full of water stains, and there was dark green moss on them!
