Pen Fun Pavilion www.xbiquge.cc, the fastest update to the latest chapter of the Evil King Concubine: Doctor Hand Covering Sky!Late at night.

Due to the limited number of rooms, Gu Qianxue did not have a separate room, and was afraid to disturb Zhao Yaolan to rest, so he could only sleep with Gong Lingtuo.

And Marshal Zhao and Lanzhi did not think it was wrong. After all, the two had been a husband and wife. Who could have thought that the two had experienced all sorts of things, but they were just nameless?

Despite being nominal, the two in the room would not do anything extraordinary.

On the one hand, Gong Lingyun is still using Tongzigong to restore health and skill, on the other hand...the two people are really not in this mood.

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

After Gong Lingfeng washed his face, he saw Gu Qianxue lying on the table and sketching.

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

But I saw Gu Qianxue's paper saying-2KNO3+S+3C=K2S+N2+3CO2

"What do these symbols mean?" Gong Lingyun asked again, his voice paused, "Are there something in your world?"

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

Gong Lingtuo thought for a moment, and the back face was gradually shocked, "You mean, this thing can explode?" Gu Qianxue nodded, "This formula is the formula of black powder, and its formula is sulfur, saltpetre, charcoal, proportion Probably one sulphur, two nitrate and three charcoal, these three things are sealed in a fragile container in this proportion to make shells, shocked or ignited, the black powder exploded and used

Unexpected speed and power pushed the shells out, hitting the crowd and seeing the shrapnel flying into the surrounding human body, causing casualties, just like someone standing in the crowd with a very fast speed diffuser."

For a time, Gong Lingyun didn't say anything, only surprised.

"But there is a problem." Gu Qianxue said with a sigh of relief, rubbing his hands and rubbing his eyes.

"What's the problem?" Gong Lingyun sat beside her, reaching for his forehead.

His fingers are slender and powerful, but his movements are extremely gentle. Under his massage, Gu Qianxue felt that his hard scalp had been released because of long thinking."This thing is called a cannon, and its shape is like this." Then, Gu Qianxue painted the red cannon on paper and explained the principle."These are only based on my memory. They may not be precise, and there is no guarantee that they will be fired accurately. Including the ratio of the black gunpowder,

It is just a prototype of the ratio. We need to experiment repeatedly, but whether the gunpowder formula is accurate or not, how to solve the problem of shells and barrels?"

Gong Lingwei thought quietly and said slowly, "You said, if you commissioned the famous sword villa to make it, how?"

Gu Qianxue smiled bitterly, "Now you and I are infamous in the famous Jianshanzhuang, the two of us offended Dongfang Junhua and Dongfang Jun'er. Will they help us?"

Gong Lingyun also kept silent.

The two were silent, thinking of a way.

"Or, let's gather the blacksmiths in Kanto Castle and try to make a barrel?" Gong Linguo said.

Gu Qianxue nodded, "There is only this way, but there are still problems-the famous swords of the famous sword villa are not only the technology, but also the high-quality minerals of the famous sword village. We have many plains and few peaks in the Kanto city. There is no place. Looking for minerals, what can I do?"

Gong Linghui smiled, took the pen from her hand, spread out a piece of paper, and soon enough lines were drawn.

Gu Qianxue looked curiously, "Is this...?" "It's a map around Kanto City." Gong Lingxuan put down his pen and reached out his hand, "Here we are in Kanto City, and Kanto City goes north for more than ten miles. Yan Guo, and Kanto City to the south, this area outside the city is under the jurisdiction of Kanto City. After this area is in the southwest corner, here is the Xiongchi,"

Speaking, write the word "Xiongchi" on the paper.

Gu Qianxue listened quietly without interruption.

"Xiongchi sounds like a water land, in fact, there are many mountains, more mines." Gong Lingyun's voice, with a meaningful meaning.

Gu Qianxue suddenly realized, and then smiled with evil spirits, "You mean, after we rebelled, we first played the male pool and occupied the mine, right?"

Gong Lingyun nodded."But before occupying the mine, how do we send troops? Do we use this kind of cold weapon for melee combat? Although Zhao Jiajun has a large number of people, he still experienced the previous Kanto City incident. The grandfather said that Zhao Jiajun's number is only half of the heyday. The quality is also uneven

.If Gong Lingyao is okay without defense, we can be surprised. If he has defense, we are afraid that he will suffer heavy losses."Gu Qianxue said.

Gong Lingkuan sighed, "Gong Lingyao is cunning, and since he has moved his mind, he must be guarded," the voice paused, with a search, "Can't you say that the cannon cannot be used first ?"

Gu Qianxue shook his head with regret in his eyes, "If there are precision and formulas and drawings, it is natural to do everything possible, but now I only know a rough prototype, which requires a lot of time and energy to experiment and improve, I am afraid ... It will not be able to hydrolyze near fire."

Gong Lingkun's eyes flashed, "Wait, Qianxue, you just said that gunpowder is made into a shell in a container, under what conditions will it explode?"

"Shock and light." Qian Xue answered.

Gong Lingyun narrowed his eyes slightly, thinking for three seconds, then pulled out the paper and drew it.Gu Qianxue was surprised when he watched, "This is a catapult? Right, we can make a shell and bomb it with a catapult! There is no artillery on the other side. It is not a two-sided match, it is rather a unilateral harvest. Without precautions, there is no need to consider such as range

, Caliber and other factors, as long as enough catapults and black gunpowder bombs are built, you can enter the battle!"

Just when Gu Qianxue was happy to start designing the shells, he was hugged and it was Gong Lingyun.

"What's wrong with you?" Gu Qianxue asked carefully, holding the pen. "Did you think of something sad? Don't worry, Qin Fei and they are safe."

"No," Gong Lingtuo said, "It's just emotion again, thanks to you."

Gu Qianxue smiled, put down the pen, reached out and patted his back, "Me too, experienced ups and downs, thanks to you being around, although many times I don't know it is you, thank you."

The two embraced tightly.

"Qianxue, will you never leave again?"

Gu Qianxue smiled, "Okay, never again."

In the next two days, Lan Zhi and Gu Qianxue created a unique transfiguration technique, not something on the face, but a poison.

After taking this poison, the skin color will become dark, the joint edema will be thick, and the facial features will be even more mad. As long as you continue to take the medicine, you can maintain the effect of discomfort.Gong Lingtu is no longer as cold-tempered as before, and changed to another rough appearance. He has a wild temperament that is similar to Marshal Zhao.
