Seeing that the fire broker in Yang Dui was about to be ignited, and he was approaching the hole of the biogas pool for fear of death, Li Xiu was so scared that he shouted "No", and then he jumped and kicked up.

As a fighter, Li Xiu never expected that he could jump up and kick people like Huang Feihong in later movies. It was a reappearance of Foshan's shadowless foot. With Yang Dui's scream, he was kicked to the ground by Li Xiu, and the fire sack in his hand flew out. After Li Xiu landed on the ground, he still didn't feel at ease and kicked up until the fire stomped out.

"Ji... what are you doing?" Yang Dui was kicked by Li Xiu for some reason. Fortunately, the ground was soft and he was not injured. However, Li Xiu was so suddenly scared him and was also a little annoyed.

"Yang Dui, I will tell you solemnly that biogas is not an ordinary thing. It is actually very dangerous, especially when it encounters open fire, it is easy to explode. If it weren't for me just now, we might have died without a complete body!" Li Xiu said with anger at this time.

"Uh? What is an explosion?" Yang Dui was immediately frightened and lost his anger when he saw Li Xiu's angry look. He looked at Li Xiu with a confused look on his face and asked.

Hearing that this stupid and bold didn't even understand what an explosion was, Li Xiu couldn't help but shook his head powerlessly, then thought for a while before speaking: "You should have heard of gunpowder, right?"

"Of course I heard of this. Before, the King of Qin relied on gunpowder to defeat the 200,000 Turkic army. It is said that gunpowder is a divine object given by God. "But when he said this, Yang Dui suddenly thought of something and stared at Li Xiu in admiration, "But I heard from my uncle that this gunpowder was presented to the King of Qin. I am afraid that only people like Jijiu can create a divine object like Gunpowder!"

"Gunpowder is not a gift, and its power is not as great as the legendary one. However, gunpowder is used to kill the enemy by explosion. If the biogas pool under our feet explodes, its power will definitely be greater than that of gunpowder. At that time, we two are not even easy to find a corpse!" Li Xiu said at the end, and also showed a solemn expression on his face. Yang Dui was able to build this biogas pool alive, which has to be said that his luck was simply amazing.

"Ah? Biogas... will explode like gunpowder?" Yang Dui suddenly showed a fearful expression when he heard Li Xiu's explanation, but soon he was a little confused and said in confusion, "But when the biogas was just built, I went down to see it. I also had torches at that time, so nothing was wrong?"

"The biogas explosion requires a certain concentration. When you first built it, the amount of biogas is produced is relatively small, so there is nothing. But now the biogas can be burned. At this time, only a little spark is needed, and the biogas inside may explode. So you must be careful in the future. In addition, the action you did when extinguishing the biogas just now is also very unsafe..."

As Li Xiu said that, he explained some safety matters that biogas should pay attention to. Li Xiu didn't know much about biogas, but later generations often used natural gas to cook, and knew some necessary safety knowledge. In addition, he also vaguely remembered what he learned when he was in school, and it was explained in an orderly manner.

Yang Dui was sweating coldly while listening. It was not until this time that he realized how many mistakes he had made before, and he deserved to die because he was very lucky, otherwise he would have died many times before.

"Okay, there are all the safety things that biogas needs to be paid attention to. If you want to continue researching in the future, you must pay great attention!" Li Xiu concluded at last.

"Jijiu, I can't remember so much you said for a while, and what if I accidentally exploded?" Yang Dui also said with a sad face. After hearing Li Xiu's call, he was so scared that he didn't dare to play with this biogas anymore.

"This... biogas does have many safety issues, and there is no shortage of fuel now, so it is not very practical. I think it's better not to study it for the time being." Li Xiu also saw Yang Dui's concern at this time, and said immediately. In fact, he mainly did not want this capable subordinate to be in danger, otherwise it would be difficult to pass Yang Nong's level alone.

"Okay, I'll listen to the sacrificial sacrificial wine!" Yang Dui nodded without hesitation when he heard this, without any dedication to science, which made Li Xiu a little disappointed. He thought Yang Dui would persevere, so he prepared some reasons to convince him, but he didn't expect that it would not be useful at all.

After knowing the danger of biogas, Yang Dui didn't dare to stay here. He sealed the hole of the biogas pool with bluestone again, and then left Li Xiu. However, when he was on the way, Yang Dui suddenly said embarrassedly: "Sacrifice, I heard that you are going to be a father soon?"

"Yes!" Li Xiu replied with a smile.

"That's a coincidence. My wife is about to give birth!" Yang Dui first showed a surprise expression, but then he was embarrassed to say again, "That... I didn't like studying before, and I haven't given my child a good name yet. Can you see if I can..."

"You want to name a name too?" Before Yang Dui finished speaking, Li Xiu slapped his forehead and interrupted him, and then said helplessly, "Yang Dui, let me tell you honestly. It has nothing to do with whether you are studying or not. I haven't named my child well yet, and I have two children. I'm almost having a headache now!"

"Uh? I didn't expect that the priest would suffer from the pain!" Yang Dui was stunned when he saw Li Xiu's painful appearance, and then he said with some sympathy. Since he was a father, he also had a deep understanding of this pain.

The next morning, Li Xiu asked someone to prepare a carriage, and then went to the Ministry of Agriculture to pick up Yang Nong to Chang'an City, preparing to find the shipbuilder he recommended. However, while on the way, Li Xiu was also thinking about his family affairs, because the childbirth period of the wardrobe had passed, but there was no movement for a long time. Although the midwife said it was normal for a few days to be late, Li Xiu could not help but worry.

"Li Jijiu, what are you thinking?" Yang Nong on the carriage couldn't help asking when he saw Li Xiu's thoughts.

"It's nothing, I just think about some family matters." Li Xiu replied with a smile, then remembered his purpose today, and asked curiously, "By the way, I don't know what the person you recommend, and what is his origin?"

"Haha, this person's life experience is a bit complicated, and now he is just an ordinary citizen. You will know when Li Jijiu meets him!" Yang Nong did not answer Li Xiu's words, but instead smiled mysteriously. (To be continued.)
