"What is a steam engine?" Li Chengqi asked following the words. He knew that if Li Yi made something, it was guaranteed to be a good thing.

"Steam engines actually involve sealing issues, which don't necessarily have to be rubber. Steam is the gas used to steam things, and the pressure is very high."

Li Yi didn't explain it in detail. It's very difficult to talk about physics.

"Brother Yi, you mean to blow the wind to drive the windmill?" Li Chengqi understood.

Li Yi: "..."

He didn't know what to say. It turns out that ancient people were not stupid. They could think of it all at once?

"Yes, blow with air, just this air..."

"Brother, I understand that when playing the trumpet, the breath must be concentrated. There is also a hole in the flute and flute, and a lot of air rushes through it, and the sound is louder."

Li Chengqi understood again and gave Li Yi an example.

"Yes." Li Yi found that he couldn't say anything.

"Then you build it slowly. Once it is built, you can use it to replace manpower. Just make a fire with steam. Control the water and air and blow it."

Li Chengqi nodded seriously.

"Isn't that right? I've been boiling water all the time." Li Yi admitted.

Is an aircraft carrier powerful? Its power is to boil water.

Even if it is a nuclear-powered submarine that uses electric drive, it still boils water. Otherwise, where would the electricity come from?

When it was time for lunch, both of them stopped eating and drank.

Li Chengqi muttered and went to make canned seafood in oil and left, while Li Yi went back to the study to copy books.

For a few days like this, the people with fields began to plant cotton and brought cotton seedlings back from Lijiazhuangzi.

Before harvest time, people who did not participate in tea picking went to dig ditches and build water nets.

The prisoners also went into battle. They only needed to be fed and did not need to pay wages.

The entire Jingzhao Mansion became a big construction site, and people from other places came here to earn wages.

This is not the usual amount of money for hiring, it is three times as much.

The Ministry of Accounts has money and pursues speed.

There has been nothing going on in the court recently, Yao Chong said in a relieved tone.

There was a small court meeting in the morning, and Yao Chong came out to explain the situation.

"In the area east of the Taihang Mountains, as soon as locust seedlings appear, local people drive chickens and ducks to eat them. There are also businessmen who buy locusts at the price of rice, and many children go to catch them."

He talked about places where there was no large-scale locust plague last year.

As soon as the locusts appeared, the people were eager to bring out the chickens and ducks to eat.

Merchants raise pigs and buy them with the price of grain. A pound of locusts is equivalent to a pound of rice.

Children go out to catch locusts and catch a lot of them in one day. When they come back, they exchange them for the same weight of rice.

There is absolutely a difference between a piglet eating a pound of locusts and a pound of rice.

Locusts are high in protein. If you are raising pigs, it is cost-effective to feed locusts with pigweed.

"Are the people afraid of the locust god?" Li Longji asked again.

"The people offered incense to the Locust God and thanked the Locust God for sending locusts." Yao Chong said in a dumbfounded voice.

The people know that the best time to catch locusts is now, and they don't want to wait until the locusts are overwhelming.

And then while pretending to thank the Locust God, what on earth are the people thinking?

"Report, urgent report from Songzhou, Your Majesty, urgent report from Songzhou." Before Yao Chong could figure out what the people were thinking, a voice came from outside.

The palace maid and eunuch immediately went to find water and oxygen bags. It has become a habit now. If there is an emergency, this is what they need, as well as sugar.

Because in the past, some people who were in urgent need of reporting ran over with their last breath, then fell to the ground and never got up again.

Now everything is provided. When we arrive at the place, we take oxygen first, and we get on the cart from the moment we arrive at the Imperial City.

On the way, they sprinkled water to cool down, and someone prepared to perform cardiopulmonary resuscitation.

"I'm fine. I drank sugar water when I came back. I'm Yulin Feiqi." The carts came, six carts, obviously there were six people in this emergency call.

The person in the lead was explaining to the others that he had been doused with water.

"Take a few breaths of oxygen first." Li Longji ordered.

So each of the six people held an oxygen bag and breathed there with depressed expressions.

"Your Majesty, I'm ready." The leader took a few puffs and couldn't bear it anymore.

"How is the situation?" Li Longji asked with a smile.

"I, Yulin Feiqiu, killed sixty-seven brothers and didn't bring them back. They were pickled with salt." The leader first said something sad.

"Yeah!" Li Longji closed his eyes.

"The Tibetans attacked Songzhou City. We launched a timely attack, killing more than 2,000 enemies and capturing more than 10,000 prisoners. Another 2,000 Tibetan cavalry went to attack Ningyuan Town.

My Yulin Flying Cavalry released two hot air balloons to detect the enemy's situation.

The main force directly entered Tubo, killing more than 4,000 people, capturing more than 6,000 people, and rescuing 3,111 Tang people.

We are currently negotiating with Tibet to exchange prisoners. Our army won a great victory. Tibet cooperated in attacking Ningyuan Town and the army retreated urgently."

The six leaders who came back from Yulin Feiqi told the results of the battle.

They launched a besiege of Wei to rescue Zhao, and rescued many of their own people, forcing the enemy to return to defense.

"How many soldiers died in Songzhou?" Yao Chong, as the Minister of War, thought of Songzhou's men rushing in front and Yu Linfei riding behind.

Then sixty-seven of the Yulin Feiqi died, what about the casualties in Songzhou?

Yu Lin Feiqi was silent and looked up at Li Longji.

"How much?" Li Longji asked.

"Two hundred and ninety people." The leader of Yulin Feiqi gave the answer.

"How did you fight? Your Majesty." Yao Chong asked.

Li Longji nodded.

"Guo Changshi always stared at the Tubo generals and beat them, more than a thousand steps away, with at most four shots. The enemy generals were guaranteed to be killed."

Yu Lin Feiqi gave an answer, it's that simple.

"Isn't the proportion of Yulin flying knights dying too high?" Yao Chong discovered the problem again.

The man looked at Yao Chong with contempt in his eyes: "The Yulin Flying Cavalry is called the Yulin Flying Cavalry. It rides, attacks the formation, and the cavalry charges the formation."

"Fei Qiu Yulin personally charged into the formation?" Zhang said, muttering beside him.

"The Fei Qiu can dismount and form a formation. I, the Fei Qiu, don't have any arms that cannot be used. The strength of the Fei Qi is due to the flying cavalry, combat power, and military soul."

The man on the Yulin Flying Rider straightened his neck and said, his eyes full of pride.

"Okay, now we can exchange for many people of our Tang Dynasty, and spread the word to the world!" Li Longji was even more proud.

Your own private army is not a gorgeous soldier bought with money. When it is time to charge into battle, you will still rush to the front.

After the Umrah meeting was over, the dispatchers rushed to various state capitals with the news to spread the news.

Everyone in the court, no matter who they represented behind them, was now silent.

Another battle was won, and more importantly, money was used to raise soldiers. They were not weak, and they could go deep into the enemy's territory and fight.

The most terrifying thing about an army is that it possesses a military soul, and Yulin Feiqi has achieved that.

From now on, Yulin Feiqi will be invincible.

"Brother Yi has trained me a good soldier." Li Longji brought the memorial to Queen Wang's palace. He was not in a hurry to correct the memorial and said to Queen Wang first.

"I knew it earlier. The training methods of the Yulin Flying Cavalry are different from other armies. Saburo, is there any news from Songzhou?"

Queen Wang immediately thought that she must have won the battle, and it was a great victory.

"The casualties are almost one hundred to one. I believe more people will die in Tubo in the future. They don't have the medical technology provided by Yi Di."

Li Longji came over, put his arm around Queen Wang's shoulders and said.

He knew that after the Battle of Songzhou, Tubo would be frightened when facing Yu Lin Feiqi.

The killing was too ruthless. If Yi Di had not been soft-hearted and would not have exchanged personnel with the other party, the people of the Tang Dynasty would not necessarily have died if they were caught.
