1. "Don't say what you shouldn't say, don't ask what you shouldn't ask." A long line of people leaned against the wall, reciting the rules of secrecy that Yun Hao had urgently made. Wen Daya personally sat at the table to supervise, and he didn't plan to let go of all the people in the academy, including the vegetable washing aunt. Either choose to memorize the rules of secrecy, or roll up and get out. A new place to work has been found, Difu!

Careless, careless. I trusted the simplicity of the Tang people, and I also suffered enough from simplicity. People in these years have no sense of secrecy and no conspiracy. There is no thrilling spy war blockbuster, but Wu Yuanshuang's steward invited a few workers of the academy to drink two meals. The secret of gasoline was revealed, and the cost was outrageously low.

The worker who leaked the secret is gone, and the whole family is gone. After Su Jin came, even their family was gone. Yun Hao thought that if he wanted to find them, it was best to ask Hades.

Li Yuan was furious, he couldn't bear the fact that he hadn't used the advanced weapon yet, and he was actually taken by the enemy. The words are very absolute, as long as a fire oil bomb falls on the head of the Tang Dynasty soldier. Li Yuan would put Yun Hao on armor and send him to the front line, so that he would know what it meant to be cocooned.

The road to the west was densely packed with soldiers, and the soldiers were eager to inquire about the flies that flew by. The reward for catching Wu Yuanshuang is very rich, so rich that it is no problem to solve the problem of eating and drinking for three generations.

Yun Hao also scratched his head, the leakage of the formula of gasoline was a big accident. Thankfully, the formula for the gunpowder didn't leak out. In fact, Yun Hao himself did not understand the formula of gunpowder. Purifying this thing with sulfur is so fucking hard. The recovery of sulfur vapor alone is a matter of life, and it is no problem to collect some on a small scale. It is basically impossible to supply military supplies on a large scale.

The gasoline refined by the farmers was carefully studied and estimated according to the output. That is, in the last six or seven days, the workers who leaked the secret also said that the mysterious person found them ten days ago.

In other words, the news has not been leaked for too long, which is good news. In any case, the news must be nipped in the bud, and there is no shortage of oil in the Western Regions. Once Xue Rengao grasps the secret of gasoline, it will be extremely difficult to fight him in the future.

"Boom!" After a thunderbolt on a sunny day, it is flying sand and rocks. The Tang monarchs and ministers who were watching from the mountains in the distance were stunned, and they watched as dozens of pounds of stones actually flew into the air. When it fell, it whistled and smashed a huge hole. One hundred catties of gunpowder, with this power, Yun Hao is still satisfied.

"This is the power of gunpowder, and it is not enough to describe the cracking of the mountain. With this thing, even the strongest city walls will be decorations. Further research is underway at the academy, and it is believed that it will not be long before the Luoyang front line will be equipped. When the time comes, the princes will wait for the news of the fall of Luoyang! Yun Hao didn't look sad at all, and explained foaming at the side.

"Hmmm! If this thing is used, it is indeed a nightmare for all fortified cities. With this thing in Datang, there is no city in the world that can stop the Datang Iron Cavalry. Li Yuan also looked very excited, patting Yun Hao's shoulder and being very satisfied.

"Tell me if you need anything, as long as you want me to provide for it all. Li Daliang, the household department is not allowed to delay the money and food in this matter. Li Yuan immediately gave instructions, and the gunpowder project immediately became the No. 1 project of Datang.

"No!" After Li Daliang bowed and agreed, he arched his hand at Yun Hao. The household department is not rich now, and the front line is still using soldiers. He only hoped that Yun Hao would not open his mouth widely, according to previous experience. After the nobles got such a warrant, it was usually a whale opening their mouths.

The position of the head of the household department can be regarded as a family industry for Li Daliang. His ancestor is Li Yanzhi, the secretary of the Northern Wei Dynasty, who knows the faces of these nobles best.

"Lord Shangshu, don't worry, the kid won't make it difficult for you. In a while, Mr. Hikohiro (Wen Daya) will carefully plan with you. Yun Hao smiled and arched his hand to Li Daliang.

The ministers of the Tang Dynasty exchanged their heads one by one, praising the power of gunpowder. Some of them are clever and are already planning how to send their children and nephews to the academy. If a family can grasp this secret, it will be invincible at all times.

The excited Li Yuan once again took the ministers to visit Lishan Academy and tasted the food in the cafeteria. He visited the students and workers who had memorized the rules of secrecy, and shook hands with them one by one. As for those who can't memorize the rules of secrecy, the palms of their hands are beaten like bear paws, and they are even more kind. As for the handshake, the other party's screams are regarded as singing.

The eldest grandson, Shunde, once again lamented that the strength of his political enemies did not benefit him at all. I thought that what happened last time could bring down Yun Hao, but it was only three or two days away. This kid is jumping around, and he looks like the weather. I don't know if it's because the Tianshan Snow Lotus has a good medicinal effect, or if this kid is lucky and shining. Anyway, I need to hide from this kid in the future. Having an opponent with tenacious vitality like Xiaoqiang is simply a nightmare for the eldest grandson's family.

Pei Lin and Li Jiancheng both looked at Yun Hao, they knew the inside story. This kid's zodiac belongs to the fox, and at this time, he actually invited all the courtiers to come and see the gunpowder test explosion. If there is no conspiracy in this, they will not believe it. Just a few days ago, this kid also performed a big drama with His Majesty the Emperor. The civil and military forces of the Manchu Dynasty were all played by two people like monkeys.

Wang Qi and Wei Ting were almost tricked off a layer of skin. God knows, who this kid is going to pit this time. It's right not to speak on this occasion, just with eyes and ears. As for the mouth, it should be left at home and not brought.

Yun Hao gathered beside Li Yuan, and the two talked and laughed while walking. From time to time, Yun Hao also pointed to the newly added things in the academy and explained them to Li Yuan.

The lawn paved in the spring had turned yellow, and Li Yuan watched with interest as the students of the academy played a football game. He liked this kind of game very much, and he kicked twice excitedly. It's just that his feet are not good, and the ball made of pig urine bubbles was kicked by him to the branch of the tree, and it leaked. That's it, and shameless sycophants. insisted that His Majesty the Emperor was very good at kung fu, and kicked the ball to pieces.

It wasn't until the sun set in the west that Li Yuan left the academy unsatisfied. He was the emperor and had a high specification for spending the night outside. The academy is not yet able to meet the emperor's request to stay overnight.

The old fisherman looked at Yun Hao who was smiling in puzzlement, and in the afterglow of the sunset, he saw Yun Hao's fox-like smile. This kid wants to trick people again, this is the first reaction of the old fisherman.
