"First, the construction cost is expensive. Whether it is sights, precision gears, crossbow strings, or bows, they are all big heads that cost money, and it takes at least tens of thousands of chunks to build such a unit."

"Secondly, the Jin people are not idiots. After the first general is killed, it will be difficult to kill them again. They will inevitably act secretly and will inevitably change."

"Third, this object is so sophisticated that even if it can be disassembled and maintained, it is still not suitable for large-scale installation of troops."

"I tried my best to do something like this that proved my idea. It looked a bit tasteless and a pity to abandon it. So I think this long crossbow was built and placed in Shanhaiguan to scare the Wanyan family."

Li Gang pointed to the huge machine and said a lot of things, saying that Zhao Huan was a little doubtful whether Li Gang was wasting national treasury.

After saying that, Li Gang smiled bitterly, and made such a weapon, but he looked like a good person.

The cost of hundreds of thousands of taels of silver, the extremely high transportation cost and the extremely high maintenance cost, this weapon has no possibility of being equipped with a large army.

What did you make yourself?

"Da Zai Li is worthy of being Da Zai Li. After telling out the advantages and disadvantages of this thing, aren't you afraid that I will punish you for wasting national treasury?" Zhao Huan shook his head, patted the huge mechanical crossbow, and glanced at Li Gang.

Zhong Shidao once told Zhao Huan that he would keep his mission in mind and not forget his original aspirations, but Zhao Huan did not slacken.

Li Gang actually wanted to be a moral saint from the end. At this time, shouldn’t he advocate the power of mechanical crossbows and exchange for some rewards?

When it comes to large-scale application, raise various difficulties and make the project end?

This is the common routine.

When I arrived at Li Gang, I actually made the dispensable uselessness clearly.

"But I think this thing still has its own meaning," said Zhao Huan.

"The mechanical structure of this thing is so exquisite. It seems that it is a masterpiece of Li Dazai's learning of machinery for a year. If you spend some money, you can spend some money. Some experience in these structures can be used on ordinary bed crossbows and decisive chariots. These hundreds of thousands of chunks of stalks will not be wasted."

"What the official said is." Li Gang nodded. Indeed, Li Gang also used improved bed crossbows for these mechanical structures.

"This object's Thousand Mile Mile Mile Mile Mile Mile Mile Mile Mile Mile is so exquisite. Although Liu Shaoqing did not explain to me what it means to see what it means to see the enemy, it is absolutely useless when this object comes to the battlefield to look at the enemy's situation! It's a good thing to know yourself and your enemy and win every battle."

"This thing is full of treasure, and Li Taizai is humble." Zhao Huan affirmed the efforts of Li Gang, Li Gang, Su Xie and others this year.

What is the purpose of scientific research? It is technical accumulation and trial and error.

Making some small mistakes, going on wrong paths, making some crooked and even making some examples is not scary. It is only possible to constantly explore the right path, not lacking this spirit, and wasting some money.

I have money.

Zhao Huan was unwilling to attack the city and lost his original role. As the highest scientific research unit of the Song Dynasty, they existed to dive into the endless boundaries of creation, be the sharpest awl in the world, pierce the inherent shackles, and break into a new world.

"Everyone has rewards, and there are rewards." Zhao Huan happily patted the mechanical crossbow and said, "Liu Shaoqing, I will give me a thousand-mile mirror to the palace another day, so that I can play with the children."

Zhao Huan looked at Li Gang and asked, "Is there anything else?"

Li Gang's face became hesitant and took out a book and said, "This is Chen Gui, Chen Shaoqing, a book about thorn cannons and muskets written by him is being compiled. It has not yet been completed, but there has been drafts, and it is mostly written by his dreams."

"Oh?" Zhao Huan knew that Chen Gui was in Yunzhong Road now and had time to write books after the war. As expected, the biggest romance of literati is writing books and speaking!

Zhao Huan took the book and read it, and the title of the book puts Zhao Huanlei's outer and inner body.

"Is this written by Chen Gui? Why do I feel that the writing style is very different from his book "De'an City Defensive Record" and "Occurrence and Defensive Strategy". Are you sure it's not a ghostwriter?" Zhao Huan said with a lot of laughter and cry.

"Fire Dragon Holy Artifacts and Divine Machine"!

If Li Gang hadn't told him that this book was a way to write about the use of firearms, Zhao Huan would have thought it was a weird book.

[I was young, I was familiar with Confucian books, studied them carefully, traveled to the lakes and seas, and visited Youdao. One day, I visited the Qingyuping on Tiantai Mountain.

In the cave, I met a Taoist priest with yellow crown and black clothes, blue eyes and long beard, and chanted under the pine tree. I bowed to him, and I was floating and truly awe-inspiring god.

Also...]

Zhao Huan roughly read the book, and the beginning was mysterious. Chen Gui said that he met a Taoist and did not know his name. Then he passed down this book of Fire Dragon God to assist the wise king.

Then the Taoist sent Chen Gui out of the Zhenyuan Hua Cave Heaven in Wuyi Mountain. He looked back and saw the misty smoke and the forests hidden, and he didn't know what he knew.

Zhao Huan felt that when Chen Gui was writing this book, he was definitely drunk.

The preface is inconsistent with the latter words. Sometimes the Qingyu Cave Heaven on Tiantai Mountain, sometimes the Zhenyuan Cave Heaven is indeed a work of the stream of consciousness.

But there are serious military tactics behind it.

Zhao Huan roughly looked through it and it was roughly divided into three types.

First, the general discussion of fire attack, fire attack heaven, fire attack place, fire attack weapon system, fire attack magic medicine, fire attack soldier ring.

The second is to record that various types of firearms are divided into eight kinds of magic weapons that are cultivated by immortals, including land battles, water battles, ambushing, stealing disasters, defending the city, and attacking the fire dragon holy weapon.

The third is various methods of making gunpowder, such as various medicine prescriptions, rotten fire, reverse fire, and magic medicine.

Zhao Huan laughed out loud as he looked at it, because the name of the firearm here was really ridiculous.

"Wooden man fire horse sky thunder cannon, fire beast rolling ground speed car, drilling wind god fire meteor cannon, eight-sided whirlwind spitting mist thunder cannon, nine-arrow drilling heart poison fire thunder cannon..."

"Hahaha!" Zhao Huan looked at the naming method of these land war artillery and thought of Zong Ze's decisive chariot, and felt that Zong Ze's naming was more prosperous.

Are these inventors of the Song Dynasty all had severe patients with dystopia?

However, Chen Gui's book is very interesting. If you don't write a book, you will never starve to death.

Zhao Huan smiled and leaned backwards, handed the book to Wang Bing to look at it. Wang Bing flipped it casually and saw the forty-nine arrows of Feilian, the flying water skiing magic oil tank, the water-underbolt Dragon King Cannon, and the flying wave magic armor of the river and sea.

He thought of his Bhu Ren armor with leaves falling off, and scratched his head. Is his Bhu Ren armor the magic weapon made by immortals?

This book finally returned to Li Gang.

Zhao Huan smiled and said, "The ideas of these firearms are very good. The summary of the use of firearms is a top-notch masterpiece. But we need to change these strange powers and strange names."

"Chen Gui knew it was a bit exaggerated, but he believed that the firearm was extremely powerful, and it was given by immortals to have such power. When he got used to the power of the firearm, he would probably be calm." Li Gang smiled and put the book back into the bookcase and locked it.

When he first saw the mechanical structure, didn’t he think it was taught by immortals?

Zhao Huan actually understood that Chen Gui had such an outrageous book, so of course it was impossible for him to use his ghostwriter. Zhao Huan had seen military newspapers from Fengshengzhou.

[The momentum is like a flying dragon, the wind is fierce and the fire is fierce, the sound is like thunder and thunder shocks the sky, the realgar air is like a fierce fire, the stone yellow air is like a vast sun, the arsenic yellow air is like a smoke dragon, the slope is like a valley, the golden soldiers are like falling into the Avici Hell.]

It can be seen how terrible the first firing of the thorny cannon gave the soldiers of Fengshengzhou.

"The gunpowder was all sold out by Chen Gui himself. What was he afraid of? If you want to talk about immortals, it was him." Zhao Huan looked at the bookcase and sent it into Guangbei's study where he attacked the city. He felt relieved. There were many ideas in this book, but it still involved confidential matters.

It is better to lock it up, only the Song people can do this magic weapon.

Zhao Huan brought all the ministers to reward and comfort the many siege craftsmen who were still fighting on the front line. They are not yet able to finish the year and are one of the busiest people in the Song Dynasty.

For example, the latest type of gunpowder, according to the old conjecture, poplar trees are more explosive, and bitter fir trees are not powerful, but they are more stable. They are mixing raw materials.

Moreover, the medicine bag of the terrestrial terrestrial cannon only added terrestrial terrestrial terrestrial terrestrial terrestrial terrestrial cannon. Some people did not die after being infected with shrapnel. They made rust and sprinkled with gold juice for the terrestrial terrestrial terrestrial terrestrial terrestrial terrestrial terrestrial terrestrial terre

When the enemy fled, they still couldn't survive.

Zhao Huan was silent in making the rust process, I hope the Jin people will have a tetanus vaccine...

Also, replace the caltrops, grind it with ginger and dried ginger into powder, mix it with pepper powder, and make it into powder, which will produce smoke after the explosion.

Zhao Huan shuddered when he saw the creativity of these firearms made by Chen Gui.

Specifically refers to smoke bombs!

Of course, the name given to it by Chengui is called Feisha Shenwu, and the middle one stands blind.

Zhao Huan looked around and found that the research and development of murderers by these ancient people had reached the level of art. Seeing that the research and development and application of gunpowder had already been on the right track, Zhao Huan felt relieved.

Chen Gui's creativity is so imaginative that most of them are useless, but trial and error are a necessary path for research, and Zhao Huan is also willing to give them time.

Zhao Huan did not disturb the work of the craftsmen much. He took the minister and Wanyan Zonggan, who had two feet swaying, quietly left the military weapon prison.

Wanyan Zonggan felt that he probably had some problems. Can he really hold on in three to five years?
Chapter completed!
