It's late at night.

Due to the limited number of rooms, Gu Qianxue has no separate room, so he can only sleep with Gong lingshe for fear of disturbing Zhao Rulan.

Marshal Zhao and LAN Zhi didn't think it was wrong. After all, they were husband and wife. Who could have thought that they had gone through all kinds of things, but were nominal?

Although they are nominal, the two people in the room will not do anything out of the ordinary.

On the one hand, Gong Linghui is still using Tongzi Gong to restore health and skills, and on the other hand At this juncture, they were not in a mood.

The room is very small, except for the bed and cabinet, there is only a small table.

Gong lingshe washes his face and sees Gu Qianxue lying on the table drawing.

"What are you writing?" After wiping his face, he put the towel back on the rack and came over.

But Gu Qianxue wrote on his paper - 2kno3 + S + 3C = K2s + N2 ↑ + 3co2 ↑

"what do these symbols mean?" Miyagi asked again, the voice stopped for a moment, "is there something in your world again?"

Gu Qianxue raised his head, looked at him blankly and nodded, "have you ever seen an explosion?"

Gong lingshe coagulates eyebrow to think for a moment, then the face gradually takes shock, "you mean, this thing can explode?" Gu Qianxue nodded, "this formula is the formula of black powder. The formula is sulfur, saltpetre and charcoal, and the ratio is about one sulfur, two nitrate and three charcoal. According to this proportion, these three things are sealed in a fragile container to make shells, vibrate or ignite, and the black powder explodes, and then the shells are pushed out and smashed into the crowd with the speed and power that people can't imagine Seeing shrapnel flying into the surrounding human body and causing casualties is like someone standing in a crowd and using extremely fast speed to disperse concealed weapons

For a while, Gong lingshe didn't say anything, but she was surprised.

"But there is a problem." Gu Qianxue said his tone, reached out and rubbed his hair to hurt his eyes.

"What's the problem?" Gong Linghui sat down beside her and massaged her forehead.

His fingers are long and strong, but his movements are extremely gentle. Under his massage, Gu Qianxue feels that his scalp, which has been hard for a long time, has been released. "This thing is called a cannon, and its shape is like this." Then, Gu Qianxue painted the cannon in red on the paper and explained the principle for it. "These are just from my memory. They may not be accurate or even guarantee whether they can be launched accurately. Including the proportion of black powder, it is only the rudiment of the proportion. We need to test it again and again. But whether the formula of gunpowder is accurate, let alone how to solve the problem of shell and barrel? "

Gong lingshe thought quietly and said slowly for a moment, "if you entrust the famous sword villa to make it, how about it?"

Gu Qianxue laughed bitterly, "now you and I are notorious in Mingjian villa. We have offended Dongfang Junhua and Dongfang Juner. They will help us?"

Gong Linghui also shut up.

They were silent and thought of a way.

"Or we'll concentrate the blacksmiths in Kanto and try to make cannons?" Gong Linghui road.

Gu Qianxue nodded, "this is the only way, but there is still a problem. Mingjian villa's famous sword casting is not only technology, but also high-quality minerals of Mingjian villa. We have many plains and few mountains in Guandong City, and there is no place to look for minerals. What can we do?"

Gong Linghui smiles, takes a pen from her hand, spreads out a piece of paper, soon enough enough to make some lines.

Gu Qianxue looked curiously, "is this "It's a map around Kanto city." Gong Linghui put down his pen and pointed out, "here we are Guandong city. If Guandong city goes northward for more than ten miles, the state of Chuyan will be there, while Guandong city will go south. This area outside the city is under the jurisdiction of Guandong city. After this area, in the southwest corner, this is Xiongchi."

he wrote down the word "Xiongchi" on the paper.

Gu Qianxue listened quietly and did not interrupt.

"Xiongchi sounds like a watery land. In fact, it's mountainous, and it's more of a mine." Gong Linghui's voice is meaningful.

Gu Qianxue suddenly realized, then laughed evil charm, "you mean, after the rebellion, we first hit Xiongchi and occupied the mine, right?"

Gong lingshe nodded. "But before we occupied the mine, how did we send troops? Is this cold weapon for hand to hand combat? Although the number of zhaojiajun is quite large, it still experienced the Guandong City incident before. Just now, my grandfather said that the number of zhaojiajun was only half of that in its heyday, and the quality of its troops was also uneven

. If Gong lingyao is not on guard, we can be surprised. If he is prepared, we are only afraid of heavy losses. " Gu Qianxue road.

Gong Linghui sighed, "Gong lingyao is a cunning man. Since he has moved his mind, he must be on guard." his voice pauses for a moment and takes a kind of exploration. "Can't the cannon you mentioned be used first?"

Gu Qianxue shook his head with regret in his eyes. "If there is precision, formula and drawings, it's natural to try every means to build one. But now I only know about a rough prototype, which requires a lot of time and energy to experiment and improve. I'm afraid Far hydrolyze not near fire. "

Gong lingshe's eyes flashed, "wait, Qianxue, you just said that gunpowder is made into shells in containers. Under what conditions will it explode?""Shock and light." A thousand snow answers.

Gong Linghui's eyes narrowed slightly, thought for three seconds, then drew out the paper to draw up. Gu Qianxue was surprised to see, "is this a catapult? Yes, we can make shells and bomb them with a catapult! If there are no guns on the left and right sides, it's not so much a fight between the two sides, it's more about our unilateral harvest. Without any precautions, we don't need to consider such factors as range

, caliber and so on. As long as we build enough catapults and black powder bombs, we can fight! "

When Gu Qianxue starts to design shells happily, he is hugged. He is Gong Lingbi.

"What's the matter with you?" Carefully holding the pen, Gu Qianxue asked, "did you think of something sad? Don't worry, Qin Fei. They are safe. "

"No," Gong Linghui said, "just feeling again, thanks to you."

Gu Qianxue laughed and put down his pen and patted him on the back. "Me too. I've been through ups and downs. Thanks to you all the time. Although I don't know it's you, thank you very much."

They hugged each other tightly.

"No more snow, will you?"

Gu Qianxue chuckled, "OK, I'll never separate again."

In the next two days, LAN Zhi and Gu Qianxue created a unique face changing technique, which was not sticking anything on the face, but a kind of poison.

After taking this kind of poison, the skin color will be dark, the joint edema is thick, the facial features are also more rough and crazy, as long as you continue to take medicine, you can maintain the cosmetic effect. Gong Lingbi is no longer as cold and handsome as before. Instead, he has a wild temperament of pulling out mountains and rivers, which is somewhat similar to marshal Zhao.
