Daming: I became Zhu Yuanzhang's eldest son

Empress Ma sighed and couldn't say anything.

Even though Zhu Yuanzhang is an extremely protective person, he often has the image of a strict father in front of the children. Even Zhu Biao, the prince, is always submissive, and Zhu Yuanzhang will always say something immediately.

Only with Zhu Tao, Zhu Yuanzhang is no longer that strict father, but more like an ordinary old businessman, with a pleasant face and a happy family.

That's right, it's a bit too much, it's nothing more than always asking the child for advice, the child's things are not missing, and he even arrives in time for the meal, what is this like?

"My dad can take it if he likes it, I don't need it anyway." Zhu Tao didn't care.

In the previous life, telescopes could be bought at street stalls for tens of dollars, and even astronomical telescopes were not considered rare items.

Instead, give it to my father, it will be much safer for him to have this thing when he is doing business, he does not have to worry about horse thieves ambush, and it can also be used as a decoration, and it will save face when he takes it out.

"By the way, you also brought me two of those biogas lamps. Your mother has bad eyesight and likes to read, but she can't always see clearly." Zhu Yuanzhang thought of the biogas lamp again.

Zhu Tao laughed, why did the father seem to come to buy goods: "Okay, I will bring you the blueprint of the biogas digester, and you can let the guys make it according to the picture, but be careful not to cause a fire."

"It's okay. If someone is watching the fire, it can be extinguished quickly even if the water runs out."

Zhu Yuanzhang was not worried about fires, the palace would catch fire from time to time, if it hadn't been for the kindness of Empress Ma, many people would have been killed, but anyway, the palace is big enough, and there are always people watching, so there is no need to worry about people being hurt.

Seeing Zhu Yuanzhang's indifferent look, Zhu Tao became serious: "Father, don't take it seriously. If the methane meets fire, if you are not careful, it will not just leak water, it will explode."

"If there is a large amount of biogas, half a street can be blown up!" Zhu Tao said this just to let Zhu Yuanzhang stop being careless, but it is impossible to really blow up such a large place.

Unless it can be as big as the palace and have so many people, where else can we find so much methane?
He didn't know that his parents were really in the palace.

"Will it explode?" Zhu Yuanzhang was taken aback.

Empress Ma was also a little worried. There are a lot of people in the palace, and the water can still be controlled. If it explodes, how many people will die: "Why don't we just stop doing this? I think candles are also very useful." .”

Seeing that the two were too cautious, Zhu Tao said with a smile: "Don't worry, as long as the construction is strictly in accordance with the drawings, don't let people throw open flames into it, there will be no danger."

After hearing Zhu Tao's words, the two were relieved, and then Zhu Yuanzhang's eyes lit up, and he had a good idea.

"Son, tell me, if biogas is used on the battlefield, isn't it a magic weapon!"

After hearing Zhu Yuanzhang's words, Zhu Tao almost choked on his saliva.

I have to say that my father has a really big brain, he can think of everything on the battlefield, you are a businessman, why are you so big?Are you still planning to be an arms dealer?
It's hard to say in later generations, but in this era, if you dare to be an arms dealer, not everyone will die.

"Okay, dad, don't think about it, this thing can't be carried, it's better to bring more kerosene for bows and arrows." Zhu Tao said speechlessly: "Besides, people carry rations and supplies when marching and fighting, and you bring a team Big dung, is this plausible?"

Although the application of dung water on the battlefield has a long history, but it is limited to pouring it down for defending the city, or adding a tetanus buff to bows and arrows. Why would you want to use dung to blow people to death?

"Hey, why don't I just say it casually."

Zhu Yuanzhang was perfunctory on his lips, but he was really considering the feasibility of using biogas as a weapon in his heart.

"Don't think about dad." Zhu Tao saw his distraught look, and smiled: "Why don't you listen to advice? If you really want an explosive weapon for self-defense, I will research it for you later, and I promise it will be better than this thing .”

In fact, there is already black powder now, but it is not used much on the battlefield, and it is mainly used as a starting gun.

For example, there are often descriptions in Water Margin and Three Kingdoms, saying that a cannon fires, so and so, but that is actually a common sense error. The Song Dynasty and the Three Kingdoms did not have this thing, and it was widely used in the Yuan Dynasty and Ming Dynasty.

The gunpowder used in later generations is called yellow gunpowder, which is the real weapon that can kill people on a large scale.

"What? You can make this kind of thing?" Zhu Yuanzhang was completely shocked. He just imagined how powerful it would be on the battlefield if he could have an explosive weapon that can kill in a wide range, but he didn't expect that, seeing Zhu Tao's appearance , he is really sure to make it.

"Yes, but it will take about a year or two." Zhu Tao said as a matter of course: "Of course, even if it is made, it can only be used for your self-defense. Otherwise, if it is leaked, our family will be arrested by the emperor." Go into the palace, even if you don't die, you will never want to be free again in this life."

Zhu Tao is well aware of the horror of yellow gunpowder. Once the emperor knows about it, no matter how benevolent the emperor is, he will not let it go. At most, he will let himself, the inventor, live in the palace to ensure that the formula will not be leaked and will not help other forces. Making yellow gunpowder, and with Zhu Yuanzhang's character, I'm afraid it's not incomprehensible to kill his whole family to keep it secret.

"Good son, then you must make it as soon as possible, this thing is very useful!" Zhu Yuanzhang said eagerly, grabbing Zhu Tao's shoulder.

"Okay!" Zhu Tao reluctantly agreed.

The composition of yellow gunpowder is not difficult to find out in later generations. He has also learned it in the Jianzheng circle. The reason why he said it will take a year or two to make it is because he does not want his father to run out so soon again. It is necessary to test the potency of the drug.

In his previous life, he didn't dare to test his theoretical knowledge about yellow gunpowder, otherwise, he would have been crying behind bars a long time ago.

Finally, Zhu Yuanzhang, who was absent-minded, was pulled into the main room. After the family of three finished eating, Zhu Tao went to prepare a biogas lamp for his mother.

"Old Tang." With the pipe installed, Zhu Tao said suddenly: "Give you a batch of binoculars, and you should be able to return to the army. The merits and demerits will be offset, right?"

Old Tang stopped packing his things, and said after a long time, "Yes!"

"Do you want to go back? I still have a lot of good things, which should help you offset the crime of escaping from the military service, and even make meritorious service." Zhu Tao asked.

During his most difficult two years, Old Tang was like a brother like a father, protecting him from migration and gaining a foothold in the suburbs of Beijing. Now that his father is back, he is no longer a boy who needs to worry about being murdered and stolen. If Old Tang wants to return to the army, Zhu Tao is willing to help him.

Anyway, the good things in his hands, any number of old Tang's, are enough to exchange for a large amount of credit in the army.
