Following the prince, he had meat to eat. This was summarized by Cui Ran in the past few days. After buying a steam engine, he was praised and reimbursed all the expenses, but his status in the family has also been greatly improved.

As for the use of the steam engine, Cui Ran used Li Chengqian's suggestion to connect a press to press the brick.

The Tang Dynasty is not as good as before. After several years of rest, the people of the Tang Dynasty basically had some spare money in their hands, and the plan to build a house began to be put on the agenda. The "blue brick and large tile house" created by Li Chengqian naturally became popular.

So since you want to build a house, you naturally need bricks and cement, so it is almost impossible to know whether a machine that can press bricks and stones will generate a lot of profits without asking.

Besides, even if the people don’t buy it, the government will buy it. The Western Regions and Mobei are now constantly building cities, and the bricks and stones needed are simply unreasonable. If this piece can be bought, it would be a lot of money.

So buying a steam engine to press bricks is almost a profitable business, especially the Wang family has shares in the carbonite mine in Shanxi, which invisibly reduces the cost again. It is not impossible to make a steam engine back in a year.

After calmly analyzing all the problems, Cui Ran was almost impressed by Li Chengqian, feeling that it seemed good to follow this young master, at least after being cheated by him, there would be benefits.

Another point is that the young master has been disliked by the aristocratic family and always wants to completely settle the five surnames and seven hopes. Lao Cui is very worried that if he continues to fight against Li Chengqian with his family, he will become the first one to be killed by the young master.

Out of Mingzhe's idea of ​​protecting himself, Comrade Xiao Cui believed that the best choice was to continue merrying with Li Chengqian. Anyway, that young man could not be the commander of the bare hands, and he always needed people. As long as he and Cui Ran had a clear relationship with his family, he would not have to worry about not being able to climb up.

As for the identity of the aristocratic family, Cui Ran did not think that her identity as a side branch would receive any support. Instead, she was more likely to be sacrificed at critical moments.

In short, no matter what, Cui Ran thinks that following a certain prince seems to be more promising, and no matter whether the prince likes him or not, he always had a good relationship before. As long as he devoted himself to the prince, the problem would probably not be big.

Chang'an City felt that it had taken advantage of it because of a steam engine from the emperor to the aristocratic family. It was a happy ending in Chang'an City, while Li Chengqian in Liaodong was making his inventions again.

"How is it? Have you done it?" Li Chengqian asked as he watched Jing Yuchen fix the two steel crossbows hard on the control frame in front of the glider.

"It should be almost done, but I just don't know if there will be any hidden dangers when operating it on it." Jing Yuchen replied calmly. His flying skills in the entire Feifeng Army were the best, so the experiment naturally fell on his head after a while.

"Be careful and do what you can!" Li Chengqian instructed, then walked to the side and quietly waited for Jing Yuchen to take off with his glider.

With the last flight of the gunpowder bag, Li Chengqian had a bright idea and firmly believed that if the steel crossbow was moved to the glider, it would definitely improve its deterrence again.

Thinking of the sudden diving of the glider flying in the air, two triangular arrows flew down from the air with the momentum of diving, taking away the fragile life of the enemy general, Li Chengqian felt that the steel crossbow must be installed on the glider, and no matter how much effort it took, it would be installed.

It is precisely because of this idea that today's experiment was created.

Jing Yuchen, who had run up, accelerated, and flew countless times, completed the takeoff process in a very short time. He slightly adjusted the direction in mid-air and controlled the glider to fly towards Anshicheng not far away.

"The Tang people are here again, they are here again!" After a few days of calm, the Goguryeo once again saw the Tang heavenly soldiers that were afraid of them. Although there was only one, they still made them feel scared.

No one can forget the scene where hundreds of Tang Dynasty soldiers covered the sky a few days ago, and no one can forget the hot flames burst out from the packages thrown by the Tang Dynasty soldiers.

"What a panic? He has only one person and can't come down. What's so scary?" A guy similar to a school guard in his hand whipped the slightly panicked soldier with a whip in his hand. He raised his head and waved his fist at Jing Yuchen provocatively, as if he was saying that if he had the guts, he would come down and beat me.

The guy from Donkey Sun, I was worried that I could not find the target for experimentation, but you came to the door by yourself. Jing Yuchen in the air was wondering if he could just find a target to test it, and then fly back as soon as possible. As a result, the Goguryeo officer fist fell into his eyes.

In the coldest days, although there were a lot of clothes on his body, Jing Yuchen still felt very cold. Because the biting cold wind blew on his face, it felt like he was cutting flesh with a knife.

So when he approached the sky above Anshi City, he pierced his head in the surprised gaze of the Goguryeo officer, and at the same time, he slightly adjusted the direction and pulled the triggers of the two crossbows at his hand.

"Bang bang" two "light sounds", two triangular arrows shot out with two afterimages with the dual assistance of the bowstring and gravity. Then Yuchen's legs moved slightly, pulling the flaps of the glider, changing from diving posture to rising, and rising to the sky again before reaching the range of the Goguryeo archers.

It was not until this time that he had time to look at the chaos caused by his mansion. Unfortunately, the Goguryeo officer was not shot by a crossbow arrow, but instead two personal soldiers fell down beside him, causing some chaos.

Damn guy, he's so lucky! Jing Yuchen muttered in his heart, trying to hang the strings on the two steel crossbows at his hand, and then turn around and give the guy another ruthlessness.

But after trying it, Jing Yuchen gave up this idea.

It is difficult for him to maintain his balance in the air while completing the movement of shaking the ratchet even though he saves effort, even if the thing is standing on the ground and shaking his hands. In the air, it is impossible to complete this action.

In desperation, Jing Yuchen looked at the Goguryeo officer who had already hidden in the crowd below and spat fiercely, adjusted his direction and turned away, throwing Anshicheng, who was in a commotion behind him.

However, although he did not shoot the Goguryeo officer, he proved with practical actions that it is indeed feasible to bring a steel crossbow to the sky. Even if he cannot hang a string in the sky, he can hang it on the ground and then take it into the air. And practice it in the future, and after you can generally master the tricks, such aerial attack method will give the Feifeng Army another set of defense and attack methods.
