Chapter 240 Confirmation
However, this dizziness is also a good thing for Ma Chao, because if the air contains 90.00% methane, it will cause respiratory arrest; 80.00% will cause headaches, and 20.00% to 30.00% Symptoms before asphyxia appear, such as: dizziness, rapid breathing, rapid pulse rate, fatigue, lack of concentration, disturbance of precise movement, prolonged time and even asphyxia.

And judging from the reaction just now, the air below must contain at least 20.00% methane above five.The lower limit of methane combustion is 5.00% (volume ratio) and the upper limit is 15.00%. After this ratio is higher, an explosion will occur.Combined with the black smoke that Ma Chao found on the lamps and wires before, it is enough to confirm that there was indeed an explosion accident here before.In addition, the power supply was cut off later, and the cause of the explosion came out, which was the biogas explosion caused by electric sparks.

After obtaining these vital information, Ma Chao lay on the ground and laughed silently.Now, he is more sure of the success of his plan. "Hatohiko Chaoxiang, you old devil, let me see how you die this time!!!"

"Hmm...uh..." Fang Jue next to him also groaned unconsciously at this time, and it seemed that he was about to wake up soon.Enduring his headache, Ma Chao sat up, stretched out his hand and patted Fang Jue's face lightly, and at the same time called Fang Jue's name softly, wanting him to wake up early.

"Papa...Fang Jue??? Fang Jue?? How are you doing???"

"Well... Ma... Brother Ma. I'm already awake, you don't need to hit me anymore." Fang Jue's face was burning hot, and after regaining consciousness, he immediately stopped Ma Chao from continuing to slap me in the face .After all, although Ma Chao felt that he did not slap hard, to Fang Jue, it was a complete slap.

"Er...hehe... wake up, it's good if you wake up." When Ma Chao saw Fang Jue caressing his cheek, he grinned his teeth, and there was an embarrassing smile on his face, very embarrassment.He didn't know how to say it, just now when he hit it, he felt that the hand felt very good, and he used force unconsciously.Well, can't help it, absolutely can't help it.

"How, can you get up now? If so, let's go back." Ma Chao looked at Fang Jue who was still lying on the ground, and asked softly.

"Well, no problem, I'll get up now." Fang Jue stood up with difficulty, his shaky appearance made Ma Chao very worried.The guy hadn't recovered at all, so he forced himself to stand up.It is estimated that after taking a few steps, it is inevitable to fall to the ground.

Ma Chao took two steps forward, grabbed Fang Jue's arm, put it on his shoulder, and walked forward slowly.

After finally returning to the room, Zhang Boxin who was waiting was startled by the appearance of the two of them.He hurriedly helped Ma Chao and Fang Jue to sit down at the table. Although Ma Chao had explained that he would soon return to normal, Zhang Boxin was still extremely nervous pouring water and wiping his face, fearing that something would happen to him. Jue forcefully stopped him, Zhang Boxin would probably clean him up and check him out.

But Ma Chao has nothing but a bowl of water.This guy was force-fed another bowl of dog food.Soon, Fang Jue's symptoms of vertigo were significantly relieved.The uncomfortable expression on his face also disappeared without a trace.

"Brother Ma, I'm sorry." The first thing Fang Jue did when he recovered was to apologize to Ma Chao, feeling that he hadn't discovered the problem in time, which led to the danger just now.

"It's okay. This matter has nothing to do with you. After all, you don't know what's going on inside. Besides, nothing happened to us, right?" Ma Chao comforted the guilty Fang Jue.

"No, in the past, I... have already discovered that as long as it takes a long time, I will feel dizzy and nauseated. And just now, if I have not been busy recording data, if I reminded me earlier, I would This kind of thing won't happen." Fang Jue said with shame.This kind of thing has happened before, and I have experience, but I was negligent because of recording data.

If something really happened, keep the two of them inside.Then Zhang Boxin and Xiao Qi, who were still waiting for them outside, had no one to take care of them.And it was basically impossible for these two people to survive in Nanjing City, a dangerous place full of tigers and wolves.

"Okay, don't worry about it. Although we have encountered danger, you have to know the so-called blessing and misfortune. Although we fainted, it also allowed me to confirm the situation here. The situation here is worse than I originally imagined. It was much better, which made me more confident in killing the Japanese commander Haruka Miyohiko," Ma Chao said.

"Really? Brother Ma." After hearing the good news, Fang Jue looked at Ma Chao in disbelief.In his opinion, Ma Chao would definitely feel that this place could not help him at all, and there would be no point in staying here any longer.So, after rescuing him, Ma Chao would definitely say goodbye to them and leave.

But unexpectedly, Ma Chao told him that the situation here was exactly what he wanted.He couldn't believe it when he first heard the news.After all, in his concept, those ponds used for fertilization are useless at all except to produce some fertilizer that can fertilize the field.Also, there was a nasty smell all the time during the retting process.On weekdays, they are all existences against the wind and smelly three miles. How can they help Ma Chao kill the Japanese commander.

"Hehe, of course it's true. Do you still remember the explosion you heard about before?" Ma Chao nodded with certainty at first, and then said pretending to be mysterious.

"I remember, but isn't that incident just a rumor? No one can prove that the explosion really happened. Did it really happen?" Fang Jue asked with some doubts after hearing this question.

"That's right, there was indeed an explosion. When I checked the surviving electric light before, I found traces of smoke from the explosion on it. On the wires, there were also traces of smoke caused by high-temperature roasting." Therefore, I conclude that there must have been an explosion inside." Ma Chao said confidently.

"But, but, what caused the explosion!!! There is nothing else in there except for the rotten and fermented feces and garbage. Could it be that the feces and garbage can also cause an explosion?" Fang Jue couldn't believe it Said.
