Chapter 239

"I'll wait for you up there." Ma Chao, who was forced to eat a mouthful of dog food, turned around speechlessly and walked towards the stairs leading to the top.Thinking about how he has encountered a scene like this in the decades since he was single, this situation of being forcibly injured and unable to fight back really made him speechless.In desperation, he could only leave here in a hurry after leaving a sentence in accordance with the principle of seeing what is out of sight.Just looking at Ma Chao's back, he seemed to be running away no matter what.

"What's wrong with him???" Fang Jue asked Zhang Boxin in a strange whisper, whether he knew what was going on with Ma Chao.

"I don't know, maybe I'm impatient. Hurry up, don't make him wait too long." Zhang Boxin didn't know what the situation was, so she guessed.

"Well, I'm leaving, you have a good rest." Fang Jue felt that Zhang Boxin's words made sense, and after taking the flashlight, he hurried up the stairs leading to the upper exit.

"Okay, then let's go." Ma Chao, who was waiting at the exit, saw Fang Jue coming up, first stretched out his hand to pull him up, and then said to him.

"Well, brother Ma, come with me, this way." Fang Jue turned on the flashlight, first carefully covered the wooden boards used for shelter, and then followed the road ahead, walking in front, leading Ma Chao.At the beginning, the road was the same as Ma Chao walked when he came, but soon passed the place where Ma Chao came down before, and he still wanted to continue to extend ahead.After walking a certain distance, the two of them stopped. Ma Chao estimated that the distance would be at least 200 meters, which greatly exceeded Ma Chao's expectation.He originally thought, no matter what, the distance of a hundred or ten meters would be the end.

After Fang Jue stretched out his hand and pulled away a wooden board used to cover the ground, a more intense stench came over the pavement.As for Fang Jue, who faced the smell directly, his tears flowed from the smoke, and he retched constantly.Ma Chao was also so stimulated that his stomach began to churn continuously, and it took a long time before he calmed down.

After getting down inside, Ma Chao realized that he had taken it for granted.Under the illumination of the flashlight, I saw small pools lined up next to each other below. Each pool was about [-] square meters, extending into the darkness where the light could not reach.

The light swept across the pool, and you can see that the pool is already filled with black paste, reflecting the light of the flashlight.From time to time, the sound of "噗噗" can be heard, which is the sound of bubbles bursting out of the paste.Closer look.You can also find some leaves that haven't completely rotted inside and some things that can't tell the specific situation.

"A total of 1.5 such pools have been built here. Each pool has a circumference of five meters by five meters and a depth of [-] meters. The excrement discharged from the government toilets is filled here. Put in leaves, collected fruit peels, sacks and other things that can be completely rotten, and carry out retting."

"Currently, 23 of the forty pools have been filled, three of them have not been completely filled, and the remaining fourteen are still empty." Fang Jue walked forward while introducing the situation here.From time to time, I picked up the wooden stick on the side, stretched it into the pool to stir it, checked the situation inside, and then recorded something in the notebook on the other wall.

After seeing all the 26 pools filled with things, Ma Chao already had a mentality.He has now determined that the stench is biogas, and with these more than 20 ponds constantly producing biogas, it is no wonder that it can cover such a large area above the ground.But now, Fang Jue still needs to confirm the most important point to confirm whether Ma Chao's plan is feasible.

"Fang Jue, let me ask you, has the gas emitted by these pools been ignited?" Ma Chao asked Fang Jue.It has now been determined that this is a large-scale septic tank!Therefore, biogas will definitely be produced, but whether the produced biogas has reached the level that can be ignited still needs to be determined.

"This... I really don't know. However, I remember that at the beginning, there seemed to be a deflagration accident here! It's just that no one was there at the time, so no one could Make sure if it really happened. But after that, the lights here have never been turned on again, and even the wires have been cut off. Brother Ma, look, where are the lights installed?" Fang Jue said, and pointed to Ma Chao the electric light installed on the wall beside him.

Ma Chao stepped forward, looked at the already black light bulb and the wires behind it, and reached out to touch it.Then under the illumination of the light, he could clearly see the black layer on his fingers, which made Ma Chao laugh silently.

This discovery made Ma Chao very happy, and he turned around suddenly. Just as he was about to say something, Ma Chao felt a burst of dizziness, and his body fell to one side involuntarily.Not caring about other things, Ma Chao quickly reached out to support the wall, and said to Fang Jue, who was already a little unsteady, "Get out of here quickly!!!" Then he supported the wall, held his breath, and stumbled towards the exit.

After finally climbing up, Ma Chao and Fang Jue put the lid on with difficulty, and continued walking along the road.After walking staggeringly for a certain distance, the two of them felt that the stench in the air had eased.After confirming this again, Ma Chao and Fang Jue immediately fell to the ground, and slowly passed out.

I don't know how long it took before Ma Chao woke up slowly. Apart from feeling a splitting headache, he didn't feel anything else.After checking Fang Jue's state, he found that he had just passed out and nothing else happened, which made Ma Chao feel relieved a lot.With a wry smile, Ma Chao felt amused at his recklessness.

"It has been confirmed that there is methane gas in it. If you don't come out immediately and stay in it for such a long time, you are looking for death. If you really die here, I will be famous for a lifetime, but it will be completely destroyed. Ah. Really, how did I learn this chemistry back then? I returned it.” Ma Chao laughed at himself.

It was only when Ma Chao began to feel dizzy that he remembered that the main component of methane gas is methane. Although this gas does not cause any harm to the human body, methane will replace the oxygen in the air, thus creating an oxygen-deficient environment. If someone If living animals are in this environment, nine out of ten will die from lack of oxygen.This is why Ma Chao was recruited.
