No one could have imagined that the First Emperor would really agree to Li Chen's recommendation, and Han Xin, a little-known boy, would go to recruit Xiang Yu. After Li Chen recommended Han Xin that day, Feng Qujian and his party naturally jumped out and sneered. Li Chenxin knew that now that the entire Great Qin was leading the army to fight, only Meng Tian, Wang Ben, and Han Xin could compete with Xiang Yu. Meng Tian, Wang Ben can't be moved lightly in suppressing foreign races, so Han Xin has become the best choice.

"What, at this time, I am the commander of the counterinsurgency?" Han Xin looked at Li Chen incredulously.

Although Han Xin is very confident in his talents, he has never had actual combat before coming to the Shenwu Army, and even if he came to the Shenwu Army, he has always been training soldiers, doing the work of the head of the Shenwu Army, and he has never been exposed to actual combat. What an honor it is to lead the army to quell the rebellion with him as the commander.

"You are a commander but I made a military order to win it, although you have never experienced actual combat, but some people's war marks are engraved in their bones. You Han Xin is this kind of person, remember not to be careless, the hatred of Zhao Kuo on paper back then is still in front of you. Remember, this battle is not allowed to be defeated, and your Great Qin's national fortune depends on this battle. Li Chen solemnly admonished.

Originally, according to the consciousness of the first emperor, Li Chen was the main commander and Han Xin was the deputy commander. It's just that Li Chen has more important things to do, and second, if Li Chen is the commander, there will be some checks and balances for Han Xin. Besides, Li Chen also knows his military talents.

"Han Xin, remember that Xiang Yu is not brave, you must be very careful when facing him." Li Chen admonished.

In Li Chen's impression, in the battle between Chu and Han in his previous life, Han Xin had always lost more than he won when facing Xiang Yu, and finally defeated Xiang Yu with a battle of ambush on all sides. Of course, in this life, the soldiers under the command of the two were completely replaced, Xiang Yu was a rabble, while Han Xin was the Great Qin elite soldiers.

The duel between Han Xin and Xiang Yu is a duel between the brave fighting faction of the soldier and the fighting faction of the soldier. Both of them are leaders in their respective fields, and it is really difficult to judge who wins or loses.

Defeat Xiang Yu's rebels, this is hard. To solve the food problem, it is soft. In this quelling of chaos, only by using both soft and hard measures can the enemy be defeated.

Han Xin received the military medal and ordered the arrow to start the armament war, and the matter of countering the rebellion should not be delayed sooner rather than later. The whole world was watching Daqin's performance, if Daqin put down the rebellion by iron-blooded means, then the rest of the people who were watching would not dare to raise the anti-flag. But if they see the meaning of Daqin's little bit of external strength, they will inevitably respond in groups.

Lijiazhuang, Dharma Academy

Under Li Chen's guidance, the folk scientists of Daqin are tinkering with Daqin's first airship, which is simple but has poured everyone's efforts into it. After Li Chen explained the theoretical knowledge in detail, everyone did not encounter any technical barriers when they took action. The airship can be said to be an advanced version of the hot air balloon, which belongs to the floating aircraft, although this kind of aircraft is simple to make, but the disadvantages are also obvious, slow speed, inability to fly in bad weather, easy to explode, etc., these are his shortcomings.

"Is your leather glue good, if you fly into the sky and leak air, it will be troublesome?" The big bull urn asked angrily like a young man.

"Don't worry, I promise it won't leak, my girlfriend hasn't leaked so far?" The young man said unconvinced.

The airbags of the airship are sewn together from hundreds of pinned cowhides, and the joints of the cowhide are first sewn with dense stitches, and then pasted on them with boiled leather glue to avoid air leakage.

The lower part of the airbag is a combustion device and a rudder, while at the very bottom is a huge hanging basket. Theoretically, the fuel carried by each airship can support the airship to carry ten tons of cargo and sail three thousand miles away.

"Master Hou, how can this thing fly." Da Niu looked at the airship in front of him, and his eyes leaked countless embarrassments.

The airbag of this airship is exactly cylindrical, and when it is full of air, it is like a stick. The hanging compartment hanging under the airbag is like a large round ball hanging under a stick.

"Can fly, designated can fly." Li Chen said confidently.

Since the Westerners of the nineteenth century were able to build airships, then the Great Qin people must have been able to do the same. Speaking of which, didn't Westerners in the nineteenth century not be civilized for many years? The Great Qin people must be the best race in the world, and what Westerners can do, the Qin people must also be able to.

"Then test fly." The big bull's eyes were full of longing.

Flying in the sky like a bird has been the wish of the human heart since ancient times. Now that they can fly in the sky in an airship, how can these people not be excited, not excited.

Very, the airship has been heated to a certain extent, and it will be ready for test flight right away.

"Let's try three people first, who will go first?" Li Chen looked at the eager scientists and asked.

The piloting of the airship requires at least three people to operate, and a helmsman is responsible for controlling the direction of the airship's flight. One is responsible for the control of the combustion device, which regulates the air of the airbag according to the air pressure to regulate the height of the airbag. The other is the observer, who is responsible for observing the flight environment.

"I'll come."

"I got the rudder, I'll get it."

"I invented it, so I'll go first."

"Why, you go up, I'll go first."

"I'll go first."

Looking at the people who were arguing over the first flight quota, Li Chenxin sighed, sure enough, the scientists are all crazy. This thing has just been invented, and I can be sure that it can fly into the sky, and if it can come down, I will definitely be able to come down. It's just that it's the kind of slow and safe down, or the kind of one-step down, this can't be guaranteed. After all, any dangerous situation in the sky can be encountered, and if you really encounter danger, it is all up to you to play on the spot.

"Let's draw lots."

Li Chen knew that there would be no result if they were allowed to fight, and drawing lots was obviously the fairest way.

After a while, the results of the draw came out, the big cow, the young man who invented leather glue, a strong man about forty years old, these three people all looked at the people with envy on their heads high.

The strong man is responsible for the steering wheel, the young man is responsible for the burner, and the big bull is responsible for observation. When the burner was ignited, the heat of the airship reached a critical point and began to slowly rise into the air.

"Ahh

"Go."

"It's going to fly."

The three people on the airship could not calm the excitement in their hearts, and each let out a sigh. The airship staggered towards the sky, and everyone on the ground could only see a small black dot.

"If this TM falls, it should become a three-piece lump." Li Chen looked at the empty black dots and thought.

Yes, everyone can't even see the black spots anymore. After waiting for an hour in a restless place, the long-lost black spot reappeared.

"Cool, cool."

"I actually have a day in heaven." The airship landed slowly, and the big bull got off the hanging warehouse and said excitedly.

"How." Li Chen asked.

"Safe, quite safe. We flew around Xianyang City for a whole circle. Control the burner and air valve to control the flight altitude, and turn the rudder to control the flight direction, as long as there is no eye operation error, absolute safety. "The big bull expressed his feelings after flying.

Also, the reason why airships are unsafe in later generations is because there are too many weapons that can danger the air, and there is nothing in the sky of Daqin that can threaten the airship.

The test flight of the airship was successful, and the people of Great Qin took another step closer to their dream of flying into the sky per capita. Li Chen's small step is a big step in the development of Daqin's science and technology.
