Liu Sanwu's death is like throwing a stone in the ocean, which will not cause the slightest ripple.

Of course, someone will give him a biography, and maybe he will write his first name, but in exchange for the Liu family's linen and filial piety.

For Liu Sanwu, Hu Ye doesn't make any other evaluations, the three words of old stubbornness are enough.

Maybe this goods will become the first person to die in his Ming Dynasty experience.

The earth will not stop rotating because of a person's death, and Hu Ye's life will not be affected, because there will still be tea leaves, peanuts have been planted, and another season can be harvested after autumn.

As for the hot air balloon, fly and fly, anyway, it's not the first time.

So Hu Ye thought that he had nothing to lose this time, but he had learned something.

And now that Zhang Yuchu is the teacher of Dan class, Hu Ye's task has been reduced a lot, that is, to teach students how to reduce the drag of the plane in the Gewu class, so that the plane can glide farther.

As for the Dan class, Hu Ye still has to go to see it, because it is true that Zhang Yuchu knows how to refine Dan, but he may not be able to refine ore.

Therefore, the first batch of copper and iron ore that arrived became the experimental products of Professor Hu Ye, Zhang Yuchu and his students.

Because steelmaking is not Hu Ye's old business, he has only seen it in books, so the copper and iron ore that he bought for thousands of taels of silver still failed to refine any decent metal in the end, but made a lot of waste slag.

However, the most important thing is to let everyone learn from experience, especially the three princes and Wang Lin, when they heard that the alchemy furnace could refine an airplane that could fly with people, they studied it very seriously and quickly mastered the steps of refining.

But there are also people who are not interested in refining, such as Liu Guan, who seems to be more interested in the changes that occur during refining.

Hu Ye didn't expect that Liu Guan was not only a genius in mathematics, but also a genius in physics and chemistry, and he thought about it. The so-called science is not separated, and it is not unusual for Liu Guan to be interested in that thing.

So he began to hand over all the chemical expressions he knew to Liu Guan, he knew that he might not be able to make anything, but Liu Guan might be able to make something.

The construction of Qingtian Hospital is almost over, and Ruan An is busy with the acceptance, and the project money has also kept up, so the craftsmen still did not complain that Lou Ying deliberately delayed the construction period.

However, until now, Lou Ying didn't know that he was sold by Hu Ye. Until now, I thought that the eyes of those craftsmen who looked at him were admiration.

He thinks so for a reason, because they have made substantial progress in their research on bloodthirsty needles.

The improved powder of the bloodthirsty needle, applied to the injured thigh of the mouse, quickly stopped the bleeding, and the blood no longer coagulated.

So he and Xiao Jiuxian thought that they had invented the most effective blood clotting agent in history, and now that they have made animal real products, it is time to make human real products.

In line with the attitude of being responsible for the truth, Lou Ying made a cut in his hand with a knife. Then he applied the improved powder, but the result made him very sad, no, it should be said to be sad.

Because the powder sticks to it. Lou Ying noticed that his hands began to lose sensation and then slowly hardened, just like the reaction of early mice.

Fortunately, after a day, Lou Ying's hand gradually regained consciousness. It is estimated that the bloodthirsty needle has lost its effect.

Since then, Lou Ying has not dared to make a real deal with herself.

But this thing can't be used if it doesn't make a human body, otherwise how can it come in handy? And how can it be effective?

So these days, the two old men are always sad. Thinking about where to do the human body.

In the end, Hu Ye gave them a trick, isn't there a lot of trouble in the coastal area? The army must have captured a lot of Japanese criminals, and those people happened to be used as human bodies, and when they died, they died, and they didn't have to bear any responsibility.

The two old men threw a look at Hu Ye that matched my needs, and they embarked on the road to Suzhou Mansion.

Of course, there are also tokens from Ruan An, otherwise how could the people of Zhenhaiwei be willing to test the medicine of the two old men with the captured widows?

As for Li Yuanshan, since he was enlightened by Hu Ye last time, he rarely physically punished students, and I heard that he was writing a book recently, as if he was a memoir or something.

So the people of the entire Qingtian Academy were busy with their own things, just like the weather in June, it was in full swing.

Of course, the hottest is still Hu Ye, because he is now debugging a new hot air balloon.

He knew that the wreckage he brought back must have been handed over to Zhu Yuanzhang by Ruan An for collection, and now he had to make a new one.

With the experience of the last time, the commissioning was much faster this time.

So before the time of the month arrived, Hu Ye was ready to take off.

Saren was a little sullen, because the young master lied to her, and he clearly said that he would no longer ride in a hot air balloon in the future, why is he tinkering with it now?

In the end, Hu Ye only knew that he was reasonable, and he was emotional, this was a task assigned by the emperor, and he couldn't do it if he didn't complete it.

Just when Hu Ye was debugging the hot air balloon, the palace was also debugging the hot air balloon, which Zhu Yuanzhang ordered the people in the palace to do.

However, many people have died for this thing, and some of them have been burned alive because of improper operation, which ignited the hot air balloon. Some annoyed Zhu Yuanzhang and were ordered to chop them into flower fertilizer, and some were because the hot air balloon suddenly leaked, and then fell down and fell to death.

"Xiao Anzi, have you been on that kid's hot air balloon, what do you think of this hot air balloon?" Zhu Yuanzhang pointed to a hot air balloon in a large courtyard that was about to take off, and asked Ruan An next to him loudly.

"Back to the emperor, there are no big problems, but for the combination of various parts, it is still not as tight as that kid. Although the nozzle is the original nozzle, there should be no one who can compare to that kid for its control. Ruan An replied.

He knew that Zhu Yuanzhang had made this thing out of the wreckage of the hot air balloon he brought back, but he always had a sense of nondescriptry, and he couldn't say what was wrong, but it always felt weird.

As he was talking, the hot air balloon that had just been blown up ignited again, and the eunuch in the basket failed to escape in time.

There was no one to put out the fire with dry water, because the last time it caught fire, someone poured water on it, and it almost burned the whole palace.

Watching a eunuch burned alive, Zhu Yuanzhang just frowned and asked people to pull him out and bury him.

"Looks like there's a lot more to find him." Zhu Yuanzhang sighed, he thought that with these things, he would be able to make a hot air balloon by himself, but he didn't expect to make a four-way thing in the end, and many palace people died.

"By the way, how's that kid, is the hot air balloon ready?" Zhu Yuanzhang asked suddenly.

"Your Majesty, you don't think about it anymore?"

Ruan An still didn't worry about letting Zhu Yuanzhang go to take a hot air balloon, that thing was not a joke, and he was deeply touched by the danger.

"There's nothing to think about, this is my last wish." Zhu Yuanzhang shook his head, the hope of immortality was gone, and he hoped that he would be able to see his country in the sky before he died.

Ruan An knew that Zhu Yuanzhang had made up his mind, and this time he asked in vain.

"Your Majesty, Hu Ye should be ready, and this time he chose a thicker rope to ensure that there will be no accident like last time." Ruan An replied.

"No, don't use a rope down there, I want real flight!"

Zhu Yuanzhang shook his head, as the Son of Heaven, how could he be bound by the earth?

"Your Majesty, by all means, the slave maid has been up, there is nothing on it, only the boundless cold, your dragon body ......" Ruan An was taken aback, he originally thought that Zhu Yuanzhang was just going to heaven to be addicted, but he didn't expect to want to really fly into the sky, the danger factor has risen sharply, if there is a strong wind or thunder, it is not dangerous?

In fact, until now, he has not told Sù who is going to take the next ride, because he is afraid that if he sues Hu Ye, he is afraid that if he kills Hu Ye, he will not fly a hot air balloon again.

"Needless to say, tomorrow is the month of January, and when the time comes, call all the concubines and princes to the academy to watch." Zhu Yuanzhang said categorically, not allowing Ruan An to hesitate.

"But ......"

"What? Do you dare not listen to me? Zhu Yuanzhang's face changed, Ruan An immediately nodded yes, and then withdrew from the palace and went to discuss with Hu Ye, this time you must not go on a business trip.

At the same time, in the city of Beiping, hot air balloons also appeared.

is similar to Zhu Yuanzhang's hot air balloon, Zhu Di let the secret guard make out the hot air balloon is also nondescript, sometimes it suddenly catches fire when it flies in the air, sometimes it falls down when it leaks, and several people die.

"Bastard! This is how you learned about hot air ballooning? ”

Zhu Ditie blushed and scolded the secret guard.

"Your Highness, your subordinates were only watching from a distance that day, and I don't know the key, so please punish Your Highness!"

The dark guard trembled and knelt down.

"Rubbish! Rubbish! ”

Zhu Di kicked the secret guard away and looked at the hot air balloon that burned to ashes in front of him.

"Your Highness! Your Highness! The boss asked someone to send back a letter! ”

At this time, another secret guard rushed in and handed Zhu Di a letter.

"Zheng Da? Didn't you just give the report yesterday? Why is there again today? Zhu Di was taken aback, he gave Zheng Da a task to report on the situation in Nanjing every three days, as well as all kinds of strange things that Hu Ye had made.

Unwrapping the envelope, Zhu Di's angry face finally had a hint of joy, "I see!" I see! ”

"Come on, bring me the best female red in Beiping City, and re-refine the fierce fire oil stored in the general, and then go to King Ning's fiefdom and buy all the fire cloth for me. If there is any leakage of news, it will be killed! Zhu Di suddenly said loudly.

The two secret guards were taken aback, they hadn't heard King Yan's order to kill for a long time, could it be that there was any special information in this letter?

But they didn't dare to ask, so they hurried out to run errands.

Zhu Di came to the oil lamp, burned the letter, and then muttered to himself, "Boy, how many things do you have there, it seems that you really shouldn't have been let go to Nanjing in the first place." (To be continued......)
