Shang Wen returned to his room, unable to calm the uneasiness in his heart at all. The waitress who broke her head. And the one who broke his neck. When Shang Wen thought about it, he felt that he had murdered them, and these things could have been avoided.

"Safe. Safe. Shang Wen walked back and forth uneasily.

"Mr. Qin." Wang Ben walked in. Seeing Shang Wen walking back and forth, he was in a depressed mood.

"Sir, it's all right." Wang Ben asked comfortingly.

"It's fine." Shang Wen refused uneasily.

"I'm here to say goodbye to my husband." Wang Ben said.

"Oh, I know. So fast. Shang Wen said with trembling hands.

"Well, I'll leave in the afternoon. Together with the envoys of the Yan Kingdom. Gallop from the north. Wang Ben said.

"Oh, I see. Take care. Shang Wen's mind was not on this at all.

"Then, then I'll take my leave." Wang Ben clenched his fists and said.

"Be careful. Muskets are not ordinary weapons, so don't ・・・・・ be careful. Shang Wen didn't even know what to say. What had just happened, Shang Wen began to realize the importance of Dao safety again.

"Farewell." Wang Ben turned to leave. Shang Wen watched Wang Ben go away, and his heart became more and more uneasy. Shang Wen always felt that he should take a look. What the hell is going on.

Shang Wen decided to go and see Tu Fei, it was best to see if there were any sequelae.

Came to Tu Fei's room. Shang Wen saw that Tu Fei had woken up.

"Meet ・・・・・ Qin" Tu Fei hadn't finished speaking. Shang Wen had already waved his hand to stop it.

"Lie down. How does it feel? Shang Wen hurriedly asked.

"It's fine. Look, sir, isn't that good? Tu Fei said with a smile.

"Oh, then I'll check." Shang Wen said and stood up and examined Tu Fei's face. Mainly ears, nostrils, etc. Received a violent impact. Especially the head. The most feared thing is the occurrence of bruising, if the bruise cannot be eliminated in time. Lives are at risk. It is these areas that Shangwen examined.

"Sir." Tu Fei felt a little pain.

"How?" Shang Wen had carefully examined everything and found no blood.

"Nothing. It's just that my head is a little dizzy. Tu Fei preached honestly.

"Oh, that's good, that's good." Shang Wen was a little relieved.

"Just a concussion. Nothing. Have a good rest these days, and I'll come back to see you. With that, Shang Wen got up and left.

Tu Fei wanted to get up, but was pressed hard by Shang Wen.

The place where Shang Wen is going now is the Qin Palace, and ask about the princess, who has another female attendant.

Come to the Qin Palace. Shang Wen explained the reason to the King of Qin. The king of Qin asked the imperial physician to order Shangwen to go together.

The princess has not yet woken up. The other lady's condition was more serious. The Imperial Physician found traces of blood in his hair. It doesn't look good. Shang Wen explained the reason to the Imperial Physician Order, and for the sake of the princess's safety, the Imperial Physician Decree pondered carefully. Shang Wen also took his leave.

Hopefully the situation is better. Shang Wen said secretly in his heart. This accident was just too big. Two died on the spot. There was also a serious injury, and the princess had not yet woken up. Tu Fei's injuries don't know what to do. Shang Wen returned to his room worriedly.

Shang Wen did not eat. Didn't go to rest either. Accidents, the mind is full of accidents that happened one day today. It happened so suddenly. Some things can be avoided entirely. Some people don't have to die. Shang Wen felt a little uneasy in his heart, and felt a little guilty about the deceased.

Shang Wen stood up and rubbed his face hard with his hand. Opening the paper, all Shang Wen had to do was improve. Improve the airship.

Safety is paramount. What Shangwen needs to do is to lose the buoyancy in the airbag again. The airship was still able to hold out for a while, and was able to maintain a smooth landing for a while.

The first is the seat belt. When I made a forced landing, the impact was huge. It is unbearable for the human body. Even the simplest harness buckle is used. There is also no guarantee that the body will not be impacted. Seat belt improvements. It would be better to be able to change to a seat belt in the modern sense. All materials are leather. In order to prevent excessive force. The leather could not withstand the tensile force, so Shangwen decided to use a combination of more than two materials.

cowhide, and linen. The linen cloth should be sewn repeatedly. Shang Wen noted the situation on a piece of paper. Then, there's the car seat. Safety seats, taken on the shooting of modern seats. When I receive a strong impact. The buckle is able to pull the body forward because of inertia. As for airbags. I'm afraid it's hard to do. And now there's rubber. Only the position of the seat can be adjusted. In front of the seat, preferably in an open space. Do not crash into other places. Deals secondary damage.

This accident was basically caused by a secondary injury. Shang Wen couldn't help but think of the tragic situation of the two deceased. Shang Wen's hand holding the pencil couldn't help shaking.

Ying'er walked in with her meal. I don't want to say anything. She knows. When Mr. is thinking about problems, he is most taboo to be disturbed by others. Even the King of Qin was like this. Ying'er looked at Shang Wen, who was thinking, and felt a little unbearable. But still quietly closed the door.

With the seats out of the way, the next step is the redesign of the airship. Shang Wen sketched out the preliminary drawings of the Flying Eagle 1. The design of the Flying Eagle 1 is a continuous exploration. It is a combination of airship and hot air balloon improvements. It relies on buoyancy. The flight pod underneath the airship is equipped with a pair of straight wings, and two sets of vertical wings at the end of the straight wings. Used to control direction. Two sets of propellers provide the necessary thrust. These designs are relatively mature. problems when in case of loss of buoyancy. The people on the airship, what to do?

How to escape. Shang Wen had in mind skydiving. This is the first reaction. Because most combat aircraft, after losing their aircraft, can only take this way. Shang Wen didn't know why the Flying Eagle 1 lost its buoyancy, but what had to be solved now was the means of escape.

Skydiving, need to retrain. All pilots must learn to parachute. Umbrellas are good to say, they can be copied directly, the question is, how to train. Shang Wen was a little melancholy.

In the training of paratroopers, the first thing to do is to overcome the shoe. Falling from a great height. The foot bears the weight of this body. Therefore, it is necessary to have a good pair of paratrooper boots.

Rubber, rubber. Shang Wen reluctantly gave up the material of rubber. Great Qin is not expanding in the south now, and this resource is not available at all. There are very few options. In the case of the leather bottom, there is no rubber with carbon fiber added to the wear-resistant at all. Moreover, it is not as flexible as rubber. What paratroopers need is a good pair of boots. A good pair of boots that can withstand the impact of the weight of the body.

Timber. Shangwen can only choose this one material. This is currently the mainstream material used in all soles. But it is not wear-resistant. Resilience is also not optimal.
