Experiments are always accompanied by danger, and flying experiments must be prepared to fill with human lives.

As soon as Wu Dayuan was sent away to recuperate, someone replaced him.

"Humble Xu Ming, this will replace the driver's job."

Looking at the secret guard members who did not have a trace of timidity in front of him, Leng Feng couldn't help but sigh at the courage of the Tang people.

It's just to protect the peace and joy of the five generations, and their work treatment is enough. So what supports them in their scramble to become drivers is the guts.

The manor in the world was completely closed, and even when the plane was transported, the surrounding area of the literary academy had to strictly order all families to close their doors and not to peek.

The imperial court was curious about what the Protector and the Emperor Taishang were doing, but in the end, only Yan Xiangshi dared to ask.

I don't know what Li Chengqian told him, anyway, after Yan Xiangshi came out of the palace, he just sighed about the dress of His Majesty's study, but he didn't mention the question at all.

This is a secret, and the ministers, who have already experienced it, immediately stuffed their curiosity back into their stomachs and never inquired again.

There were very few onlookers watching the test flight of the plane, but there was one more Zhang Zhongqing, who was studying the possibility of combining gunpowder weapons with airplanes.

This time the plane was very competitive, flying more than 300 meters high, Xu Ming was also very competitive, he firmly remembered Leng Feng's advice, and when the plane was a little out of control, he parachuted.

At this height, the parachute can't be too effective in canceling the kinetic energy, if it weren't for the fact that there happened to be a pond below, Xu Ming would probably have broken his bones and tendons.

"The control module needs to be optimized, the driver's security needs to be strengthened, and the sealing of the front compartment does not need to be worried for the time being."

Writing down three items in a row in the notebook, Li Tai said excitedly: "Nengcheng, although the plane is not perfect now, but I dare to say that we have already seized the success, and we are almost tight!" ”

Li Shimin was also very excited, this was the first time he really participated in scientific research work, and he couldn't help himself with joy when he saw that the plane could fly more than 300 meters high.

After the advent of gunpowder weapons, the broken fortified city was like drinking water, and the mortality rate of soldiers was also reduced a lot. Nowadays, as long as the aircraft can be successfully studied, the enemy's army has become a joke.

You don't need to fight too hard, just use the army to contain the enemy's army, and then send planes out to directly take the enemy's lair.

There is no reason to say that Li Shimin arrogantly named this kind of aircraft Shimin. Although he has always been a bystander and has never done it, whether it is a craftsman or a secret guard, he feels that it is an honor, and he can't wait to raise his hands and feet in agreement.

In the middle of the moon, when Leng Feng was taking a bath in the bath, Leng Jing walked in, took off his clothes and took a bath with his father.

"Tell me, what are you doing today? Why did you come back so late? ”

Leng Jing is now the left squire of the Ministry of War, responsible for grain, grass and ordnance. Since all the materials have been turned into money, he only needs to approve the money on time, and he doesn't need to run around. Sitting in this position is actually a matter of seniority, and in another two or three years, Leng Jing will be able to become the secretary of the military department naturally.

With his whole body in the water, Leng Jingchang breathed a sigh of relief: "Senior Brother Emperor called some people to discuss things, and he is going to send a part of his troops to Tubo to raid some plateau tribes. ”

There are no good things in Tibet, and sending troops to Tibet is basically throwing money in vain. Leng Feng felt that his apprentice was not stupid to this extent, and after thinking for a while, he understood what Li Chengqian meant.

"Is Cheng Qian ready to attack Tubo? Or is it a coercion? ”

Leng Jing nodded: "Yes, although some of our soldiers in Datang have trained some soldiers for the Qi epidemic in Tubo, but let them go to Tubo to fight, no matter how you look at it, it will be a loss." Formal war is not advisable, so the senior brother wants to raid a few Tibetan tribes to scare them. ”

Leng Feng thought for a while before saying: "Tomorrow, after you go to the court, enter the palace and tell Cheng Qian, wait, when the aircraft is developed and mature, this can also be lent to him to increase oppression." Just like the strategy formulated by your military department before, we don't have to hide anything in the future of Datang. Only when power is displayed in the open can it play a deterrent role. ”

Leng Jing nodded, he came to his father because he had this intention. As long as the plane is exposed, it is estimated that the tribute of various countries will rise by a cut next year. The current Datang is like a sleeping dragon, and the surrounding hyenas will involuntarily help it massage and soothe its nerves, for fear that it will bring disaster after waking up.

Seeing that Leng Jing was thinking about things, Leng Feng patted the water and said, "In the position of the left squire of the military department, you don't need to work too hard except for some necessary official documents. Zhang's is about to give birth, so why do you have to care more about your family. Our family is like this, we don't need too obvious power, just a healthy and harmonious family. ”

Leng Jing opened his mouth and smiled: "Actually, I have already taken leave today, and I will not go back to work until my daughter-in-law and children are stable." ”

Leng Feng smiled, that's good, there has been no obvious boundary between right and wrong since ancient times, abolishing family affairs for the sake of state affairs is certainly called a good sentiment, but what does this make the family think? Datang has many capable people with lofty ideals, and there is no need for a cold competition to top the bar in front.

With the efforts of all the capable people in Datang, the production of the aircraft has become more and more mature, and Li Tai, who strives for excellence, even set the aircraft as a two-person pilot, with control devices in the front and rear, which infinitely weakens the probability of a crash due to device failure.

Today's experiment was different from the past, and Leng Feng and Li Tai also took out a thousand silver coins as a reward for the driver.

Before boarding, Leng Feng couldn't help but remind: "Today's goal is under the clouds, at this altitude, the temperature is very low, and people can't breathe." The steam engine has its limitations, so as soon as you reach this height, you have to descend immediately. It is no exaggeration to tell you that at this altitude, if your parachute strikes, I am afraid that we will have to burn you directly after landing to relent. Again, even so, do you want to try it? ”

I can't say this, after saying this, Wu Dayuan and Xu Ming hit each other directly, not frightened, but excited.

The more dangerous it is, the more excited the two become. Especially Wu Dayuan, who almost fell to his death, but after recovering from the injury, there was no psychological shadow left.

Li Shimin held a teapot as usual as an uncle, pointed to the steam coming out of the vent and said, "Don't ink, hurry up." As long as this guy can return to the ground safely, let's go downstairs for a meal immediately! ”

The nation's efforts to study airplanes are faster than individual exploration.

Now it is only in July of the sixth year of Yong'an, and the aircraft is approaching maturity. The rest of the problem, in everyone's opinion, just needs to be gradually optimized.

Wu Dayuan and Xu Ming roared angrily and got into the cabin.

Seeing the plane take off, even Li Shimin put down the teapot and stood up straight.

As for the others, they all gave them away.
