For three days, Li Yao never came out of his house, and Song Boming came to Li Yao many times, but he was blocked by the little girl that Li Yaoxin brought back.

That little girl also proudly said, except for me, Master Hou has no one to see!

Li Yao didn't think so much at that time, seeing that nearly a million refugees had come to Yi County, the problem of water source was the most urgent need to solve. Li Yao thought about quickly researching the black powder first, opening the mountain and blowing up the rocks, and bringing the water source over first. In order to prevent anyone from disturbing, he said to Peach, "From now on, I won't see anyone, except when you can come in when you deliver food, you must be outside the door at all other times!" ”

As a result, Tao'er guarded the door like a little hen that had just laid eggs, and she didn't even buy Lian'er, who had become the head of the maids in the Hou Mansion! It made Lian'er angry for a long time!

In the past few days, Tao'er has also been very curious about what Li Yao is doing, and every time Tao'er enters the door with rice, she is stopped by Li Yao, saying that she can go out after putting the food at the door. And she also found that Hou Ye would go to the kitchen at night, could it be that he didn't eat enough every time?

Although he graduated from a military academy, the military academy has never proposed the application of black powder in modern warfare. The most common thing I came into contact with in the military school was high explosives, and black powder, which was used hundreds of years ago, has long been eliminated!

Originally, I thought that after a simple ratio, gunpowder could be made by combining it, but after Li Yao made two large artillery battles, he ran out at night to experiment, but it was useless at all, Li Yao's cloth strip ignited, and the sparks were all in the gunpowder, but it didn't explode, which made Li Yao a little unsure of what was going on! Is it because there is no frying?

The gunpowder needs to be fried to evaporate the water vapor from the gunpowder, which Li Yao knows! But Li Yao didn't know how to fry it, so he didn't fry it, thinking about combining it first to see if it could be fried! It turned out that the gunpowder had to be fried before it could explode!

As a result, the next night, Li Yao came to the back kitchen with a few materials, lit the fire, heated the pot, and then began to put the materials, because he didn't know how long to fry, Li Yao thought about putting less materials, and less frying, and after a while, Li Yao fried several materials, and began to assemble, and assembled two cannon battles, Li Yao inserted cloth strips on the cannon battles, and went out to experiment! There is a forest in the Hou Ye's mansion, and Li Yao is ready to experiment there! Bury the cannon in the ground and set the cloth on fire. There was a "bang" sound, and the dirt in the ground was blown up several feet high!

Li Yao smiled: "It seems that I have succeeded!" ”

Since it is successful, then go back to the room immediately, and it is estimated that the Huihou Mansion will be lively!

Sure enough, after a while, the people of the Hou Mansion all got up, and the open fire insisted on investigating what was going on! And the dog head and the blind man ran to Li Yao for the first time to see if there was anything wrong with the eldest brother!

Li Yao pretended to have just woken up! was dragged to the living room by the dog head and the blind man, Wang Changzhu came to the living room after exploring the scene and reported to Li Yao, saying: "I see that the trees there are scorched, and there are traces of burning underground, it should be a thunder that fell on our mansion, in order to prevent more people from being injured in the Hou Mansion, I think the Hou Mansion should be relocated immediately!" ”

Li Yao smiled: "It's not necessary, this thunder fell from me in my dream to ask Brother Lei Gong to fall, I dreamed that we have insufficient water here, I hope Lei Gong can use the thunder to open up mountains and divert water for everyone, and as a result, Lei Gong will manifest himself!" "Changzhu, that's what you said to the servants outside!

Okay Changzhu, you go and let everyone rest first, and the dog head and the blind man come with me!

Coming to the wing room with the dog head and the blind man, Li Yao took out the cannon and said, "Do you know how that voice came from today? ”

"Isn't it the eldest brother who fell from the dream of Master Torrey?" The blind man asked.

Li Yao shook his head, those words are bluffing, I brought you here to let you know where that loud noise came from! Li Yao pointed to the five-pound cannon and said, "It's this gadget!" ”

The dog head picked up the cannon and looked at it repeatedly, and said, "What is wrapped in this paper shell?" It can be so powerful! ”

Li Yao said: "The package inside is called black powder, and the ingredients are sulfur pulled from Lu County and saltpeter from Dingbian County!" ”

The dog head sighed: "I didn't expect these two things to be so powerful combined!" Big brother, you really have the help of gods and men to discover such a secret method! ”

Li Yao smiled: "Okay, everyone go back and rest first!" Tomorrow I'll show you the power of this artillery battle! ”

After sending away the dog head and the blind man, Li Yao is ready to configure the lead gunpowder first, and he can't always stick a strip of cloth on the artillery battle!

Lead gunpowder, launch gunpowder, explosives, these three gunpowder raw materials are the same, but the ratio is different, Li Yao had been in contact with it by chance, so he knew what the dosage was.

made a fuse, Li Yao lit one, the gunpowder of the fuse burned at the right speed, and then he lay down on the bed and fell asleep!

When they got up in the morning, Lian'er and Tao'er looked at themselves strangely. Li Yao touched his face and said, "What? Do I have flowers on my face? ”

Tao'er said resignedly: "Master Hou, can you really talk to the immortals?" ”

Li Yao couldn't help but smile, it is estimated that if the housekeeper explained to them last night, the servants took it seriously! Then he quipped, "That's right! Otherwise, how could there be a thunderstorm to our house last night! ”

"Then can Master Hou not let the gods thunder at our house in the future, who did something wrong? Last night, Sister Lian'er and I were so scared that we didn't dare to get out of bed. Tao'er said nervously.

Touching Tao'er's head, Li Yao smiled: "Haha, okay, I won't ask the gods to thunder our house in the future!" ”

After playing with the little girl, Li Yao heard the voice of the county order outside.

Because I was too tired yesterday, I slept with my clothes, and my clothes were wrinkled in the morning, so I was forced to change my clothes by two little girls, and after sorting out my clothes, Li Yao went out to see Song Boming.

"Master Hou, you can finally see me!" Song Boming said anxiously.

Li Yao looked at Song Boming's anxious state and wondered, "What's wrong?" Did something happen? ”

Song Boming said: "Master Hou, why don't you tell me when you go out this time to accept refugees!" ”

When Li Yao heard that he was here to question himself, he couldn't help but say angrily: "I pull people to my fiefdom, do I still need to report to you first?" ”

When Song Boming heard that Li Yao might have misunderstood himself, he hurriedly explained: "Master Hou, I am definitely not here to question you, it's just that the migration of millions of refugees is such a major event, why don't you send someone to inform me first!" ”

Li Yao said: "Why, you're still afraid that you won't be able to manage these people!" ”

Song Boming shook his head, I didn't mean this, Master Hou, after listening to you, I will give you an analysis: "Master Hou, you are now a marquis, you should stay in the fiefdom, why did King Qi let the eldest prince go, and the second prince was not sealed, but he made you a marquis alone?" ”

Li Yao sighed and said: "This is all because I am not angry in the king, and it is also because my father and queen mother love me!" ”

Song Boming patted his thigh and said, "That's it! Since you all know it, Master Hou, why do you want to move the people and make such a big event to change the national strength! ”

"How did I change the power of the country?" Li Yao asked.

Song Boming said: "The population of the Jin Kingdom is less than 10 million people, excluding the people who are entrenched in the city, it is estimated that there are four or five million people who came out to flee the famine, and you will bring back eight or nine million at once, don't you think you are guilty of a big taboo?" ”

"Big taboo? What's the big no-no? Li Yao exclaimed.
