Shell shell must be made of iron, but the thickness of iron sheet is very particular.

It is too thin, causing shock in the process of handling and easy to explode.

If the shell is too thick, it will reduce the effect of bombing, especially if the shell is too thick.

Therefore, in the premise of transport safety, as thin as possible!

In addition, different sizes and models of catapults have different sizes of shells. For example, it is very difficult for a small-sized catapult to throw large-scale shells, and if a large-scale one throws small shells, it will be a waste of throwing opportunities.

The weight of the projectile used by the different size and power of the catapult is also different, which directly affects the accuracy of the direction and the length of the range. If it is really used in combat, the types of shells thrown by large and small catapults should also be distinguished! Some of the special attack on the enemy will use the shell with scattered pieces. When the shell explodes, the iron pieces inside will fly away like countless hidden weapons! And those who attack the enemy in the rear must use the burning

bombs, and refuel in the shells! Scattered shells should be used in some places where the enemy forces are dense, and smoke bombs can be used for those with sparse enemy forces.

Don't ask Gu Qianxue how to think of these classifications, even she doesn't know how to think of it!

It can only be said that people's potential is infinite. In the face of life and death, it can stimulate the potential that can't be imagined at ordinary times!

And how? You need to risk your life to make and experiment.

It may be several experiments, dozens or even hundreds of times.

On the way back, one in the carriage and the other outside, chatting slowly.

"Qian Xue, can someone else do this experiment?" Gong Linghui's voice is a little heavy.

Gu Qianxue naturally knew that he was worried about himself. He lowered his eyes and sighed, "no, this experiment, let alone outsiders, is me I can't guarantee 100% success. A lot of things are being explored, and I didn't work in this industry before. " He shook his head.

Miyagi thought of the power of the explosion, the mood is more heavy, "then we do together." Gu Qianxue shook his head. "No, you must be familiar with military affairs and build up your prestige. You also know my details. Although Marshal Zhao and I are related by blood, in the end We rebelled and asked them to shed their blood for us. Maybe you need to go to the battlefield in person. "

"Good." Miyagi understood.

Gu Qianxue thought that the former God's favorite outside the car had fallen into such a situation. For a while, he also sighed, "but you can rest assured that I will accompany you."

Gong Lingbi hook lip a smile, "know."

Then, the carriage entered the city, and the two men did not reply, all the way back to the Marshal's house.

They did not expect that when they left, there was a big thing. The Emperor gave Marshal Zhao and Zhao zicang two beauties, which together were four beautiful women.

Marshal Zhao is in a state of anxiety because LAN Zhi is angry.

Seeing Gu Qianxue coming back, marshal Zhao quickly called Gu Qianxue to the corner, "Qianxue, there is something You You have to bear it

Gu Qianxue only thought that there was some bad news, and the bottom of his heart fell hard, "is there something wrong with the hostages in Beijing?" This is what she worries about most! Although according to the truth, as long as she and Gong lingyao do not appear, the hostage will be safe, but the truth is the truth. Who knows what Gong lingyao thinks?

Marshal Zhao sighed, "no, it is The emperor has given four beauties to grandfather and Ling. What can I do? It's really difficult to accept the beauty given by the emperor. If you don't accept it, it will be disobedience. But if you accept Your grandmother is still angry

Gu Qianxue chuckled, "you, my grandfather and Ling Bi are both rich and lucky. Naturally, they should accept it."

"Are you satirizing my grandfather?" Marshal Zhao knew the character and conduct of his granddaughter.

Gu Qianxue's eyes flashed, "grandfather, don't worry. I'm not sarcastic. I'm going to see my grandmother." Finish saying, also do not wait for Marshal Zhao reaction, turned to the main courtyard.

In the main courtyard, Zhao Ruolan sleeps. LAN Zhi sits in front of the bed and looks at it. He can't see his expression clearly with his mask, but his whole body is filled with this unspeakable sadness.

Gu Qianxue went in and knocked on the door, "grandma, can you come here for a while? I have something to say to you."

LAN Zhi didn't answer immediately, and then he got up and sighed.

Gu Qianxue led LAN Zhi to his bedroom and let him sit down. "Grandma, can you tell me the truth?"

LAN Zhi does not understand, "what does thousand snow mean?"

Gu Qianxue said, "I want to know what task Gong lingyao arranged for those four people."

LAN Zhi thought for a moment, then shook his head. "There is no special medicine like this. The poison of Ming religion is divided into stages, such as the art of refining corpses. The first stage is dementia, and the second stage is controlling intelligence. According to this thinking, some drugs can achieve similar effects, but I can't guarantee it. "

Gu Qianxue understood, pondered for a moment, and then said, "is there a kind of magic, such as magic, that makes her think what happened, or what happened with the designated person?"

LAN Zhi was surprised, "thousand snow, grandma knows you have many ideas. Don't be so critical, or talk about your plan." Gu Qianxue nodded, "now the progress of black powder is very smooth, but we still need some time. Before that, we have to delay! To paralyze Gong lingyao! And the best paralysis is to plan. Grandfather can not accept the beauty, but Zhao zicang has to accept, NoOnly by accepting and flattering Gong lingyao, can we create more space and opportunities. Therefore, I hope that there will be such a drug that people will be bewildered. "

LAN Zhi is clear, nod, "this is no problem, I try."

Gu Qianxue held back a smile, staring at the LAN branch but did not speak.

LAN Zhi did not see hair, "why do you look at grandma with this kind of eyes?"

Gu Qianxue laughed, "I want to see grandma jealous."

The mask covered LAN Zhi's red face, but she did not cover her red earlobe. Her voice was slightly angry, "you child, do you have such a joke on the elders?"

Gu Qianxue quickly restrained his smile I'm wrong. I won't drive. " The tone changed, "but grandma, you can rest assured that my grandfather doesn't have to accept the beauty given by the emperor. These four people are Zhao zicang's

"Are you not angry?" LAN Zhi asked curiously.

Gu Qianxue shook his head, "not angry, I have experienced too much with him. It is not such a small matter that can set off a war."

LAN branch way, "small age, how to talk so vicissitudes."

Gu Qianxue smiles, but does not explain.

Another room.

In front of the four beauties, Gong lingshe thinks more about what to do and whether Qianxue will be angry? Not afraid of Qianxue and him, afraid she secretly sad! That Gong lingyao is really hateful. Even if he cuts thousands of pieces, he doesn't dispel his hatred. But at this time, Gu Qianxue arrived.
