"First, the cost is expensive, whether it is a sight, or a precision gear, or a crossbow string, or a bow body, all of them are the most expensive heads, and at least tens of thousands of dollars are needed to build such a one."

"Second, the Jin people are not stupid, after the first general is killed, it will be difficult to kill them in the future. It will inevitably act in secrecy, and it will inevitably change. ”

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

"The minister tried his best to make such a thing to verify the minister's idea, it looks a bit tasteless, and it is a pity to abandon it, so the minister thinks that this long crossbow is built and placed in Shanhaiguan to scare the group of people in the Yan family."

Li Gang pointed to the huge machine and said a lot of things to himself, and Zhao Huan was a little skeptical that Li Gang was wasting state funds.

After Li Gang finished speaking, he smiled bitterly, he made such a weapon, but it was a good thing.

With the cost of hundreds of thousands of taels of silver, extremely high transportation costs and ultra-high maintenance costs, this weapon has no possibility of being equipped with an army at all.

What did you make yourself?

"Li Dazai deserves to be Li Dazai, if you tell the advantages and disadvantages of this thing, aren't you afraid that I will cure you of a crime of wasting national funds?" Zhao Huan shook his head, patted the huge mechanical bed crossbow, and glanced at Li Gang.

Once the planter told Zhao Huan that he wanted Zhao Huan to keep in mind his mission and not forget his original intention, but Zhao Huan did not slack off.

Li Gang actually wanted to be a moral saint from the beginning, shouldn't someone else be hyped up the power of the mechanical bed crossbow at this time, in exchange for a reward?

When it comes to large-scale application, put forward all kinds of difficulties and make the project fail?

This is the common routine.

When he came to Li Gang, he actually made the dispensable chicken ribs clear.

"But I think this thing still has a meaning for existence." Zhao Huan said.

"The mechanical structure of this thing is so delicate that it seems to be the culmination of a year of mechanical learning by Li Dazai. Spend a little money, spend a little money, some of the experience of these structures can be used on ordinary bed crossbows and decisive chariots, these hundreds of thousands, not in vain. ”

"That's what the officials said." Li Gang nodded, indeed, these mechanical structures, Li Gang also used the improved bed crossbow.

"The clairvoyant mirror of this thing is so exquisite, although Liu Shaoqing didn't explain to me what is a shadow and what is, but this thing is absolutely useless when it goes to the battlefield to look at the enemy's situation! Knowing oneself and knowing one's opponent is a good thing. ”

"This thing is full of treasures, and Li Dazai is humble." Zhao Huan affirmed the efforts of Li Gang, Li Gang, Su Xian and others this year.

What is the purpose of scientific research? In itself, it is the accumulation of technology plus trial and error.

It is not terrible to make some small mistakes, embark on a crooked path, make some crooked melons and cracked dates, or even make some appearance goods, only to continue to explore the right path, not lack this spirit, and waste some money.

I have money.

Zhao Huan is unwilling to prepare for the siege of the city to lose his original role, as the highest scientific research unit of the Great Song Dynasty, they exist to plunge headlong into the endless boundary of manufacturing, to be the sharpest awl in the world, to break through the inherent shackles, and to break into the new world.

"All are rewarded, all are rewarded." Zhao Huan happily patted the mechanical bed crossbow and said, "Liu Shaoqing, send me a clairvoyant mirror into 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 a little hesitant and took out a book, and said: "This is the old rule Chen Shaoqing, a book written by Chen Shaoqing about tribulus cannons and firecrackers is being compiled, and it has not yet been written, but there is already a draft, and most of them are made by the whimsy of his dreams." ”

"Oh?" Zhao Huan knew that Chen Gui was now on Yunzhong Road, and he still had time to write books after the war, and sure enough, the greatest romance of literati was to write books and speak up!

Zhao Huan took the book and looked at it, and the title of the book focused Zhao Huan Lei's inside and out.

"Is this a stereotype? How do I feel that the style of writing is very different from the style of his "De'an Defending the City" and "Offensive and Defensive Strategy", are you sure it is not ghostwriting? Zhao Huan also said with tears and laughter.

"Fire Dragon Hallows"!

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

[Yu Shaoye, dabbling in Confucian books, studying the strategy, traveling in the lakes and seas, and visiting the way. Day trip to Tiantai Mountain on Qing Yuping 02

Dongtian, meet a soldier, yellow crown Xuanfu, blue eyes and long hair, chanting and panasonic. To the front, fluttering true fairy Feng 02

The degree is also ......]

Zhao Huan probably looked at this book, the beginning of the mystery is mysterious, Chen Gui said that he met a Taoist and didn't know his name, and then he passed down this fire dragon divine book to assist Ming Jun.

Then when the Taoist sent Chen Gui out of the Zhenyuanhua Cave of Wuyi Mountain, he took twenty or thirty miles one step at a time, looked back, but saw the smoke and trees, and did not know what he knew.

Zhao Huan felt that when he was reading the book, he was definitely drunk.

The preface doesn't match the afterword, for a while, the Qingyu Cave on Tiantai Mountain, and the other time it is the True Yuan Cave, which is really a work of stream of consciousness.

But the back is all serious art of war.

Zhao Huan probably flipped through it, and it was roughly divided into three contents.

The first is to summarize the fire attack, the time of the fire attack, the location of the fire attack, the fire attack weapon system, the fire attack magic medicine, and the fire attack military ring.

The second is to describe the eight magic weapons cultivated by the immortals, such as land warfare, water warfare, ambush, robbery, city defense, and attack on fire dragon holy weapons.

The third is a variety of dispensing decisions, rotten fire, backfire, magic medicine and so on several ways to make gunpowder.

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

"Wooden Man Fire Horse Sky Thunder Cannon, Fire Beast Rolling Ground Flying Car, Drilling Wind God Fire Meteor Cannon, Eight Whirlwind Spitting Mist Thunder Cannon, Nine Arrows Drilling Heart God Poison Fire Thunder Cannon..."

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

These inventors of the Emotional Song Dynasty are all severe patients with difficulty in naming names?

However, the book is very interesting to write, and if Shaoqing does not write a book, he will definitely not starve to death.

Zhao Huan leaned back with a smile, handed the book to Wang Yu to read, Wang Yu flipped through it at will, and saw forty-nine arrows flying cheap arrows, flying water skiing god oil tanks, underwater dragon king cannons, and flying waves in the river and the sea Divine Armor were silent.

He thought of his own Buren Armor that had lost its blades, scratched his head, and felt that his Buren Armor was a magic weapon made by immortals.

The book finally returned to Li Gang.

Zhao Huan said with a smile: "The ideas of these firearms are very good, and the summary of the use of firearms is really a masterpiece." But change these strange powers and strange names. ”

"The old rules also knew that they were a little exaggerated, but he thought that firearms were extremely powerful, and they were only given by immortals to have such power. When he gets used to the power of firearms, he will probably be calm. Li Gang smiled and put the book back in the bookcase and locked it.

When he first saw the mechanical structure, didn't he also think that the immortals had given it?

Zhao Huan actually understands that there are such outrageous books in stereotypes, of course ghostwriting cannot be ghostwriting, Zhao Huan has seen a military newspaper from Fengshengzhou.

[The momentum is like a flying dragon, the wind is fierce and fiery, the sound is like a thunderbolt and thunder, the male yellow gas is like a blazing fire, the stone yellow gas is like a bright sun, the arsenic yellow gas is like a smoke dragon, the slope is full of valleys, and the golden soldiers are like falling into hell. 】

It can be seen that the first cannon sound of the thistle cannon gave a terrible impression to the soldiers of Fengshengzhou.

"The gunpowder is all made by his own hands, what is he afraid of? If you want to talk about immortals, it is also himself. Zhao Huan looked at the bookcase and sent it into the study of Guangbei Siege City, and put his mind at ease, there are many ideas in this book, but it still involves confidential matters.

It's better to lock it up, only the Song people know how to make this magic weapon.

Zhao Huan took the ministers to reward and comfort the many siege craftsmen who are still fighting on the front line, they have not yet taken a year off, and they are the busiest people in the Great Song Dynasty.

For example, the latest gunpowder, according to the stereotypical conjecture, poplar wood is more explosive, bitter fir wood is not strong explosive, but more stable, they are doing the allocation of raw materials.

Moreover, the medicine bag of the tribulus terrestris cannon only added iron tribulus terrestris, and some gold people did not die after being hit by shrapnel, so the iron tribulus terrestris in the medicine bag was rusted and sprinkled with gold juice.

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

The process of rusting, Zhao Huan was silent, I hope the Jin people have a tetanus vaccine......

There is also a powder that replaces the tribulus terrestris, grinds it into powder with marhu ginger and dried ginger, mixes it with minced pepper, and makes it into a powder packet, which produces smoke in the sky after the explosion.

Zhao Huan shuddered when he looked at the creativity of these firearms that he had obtained from the old rules.

Smoke grenades in particular!

Of course, the name given to it by the stereotype is Flying Sand Divine Mist, and the middle one is blind.

Zhao Huan took a look around, these ancients' research and development of killing people has risen to the level of art, and seeing that the research and development and application of gunpowder have been on the right track, it also made Zhao Huan feel relieved.

The stereotyped ideas are imaginative, in fact, most of them are useless, but trial and error is a necessary way to study, and Zhao Huan is willing to give them time.

Zhao Huan didn't bother the craftsmen too much, and took the minister and Wanyan Zonggan, who was playing with two feet, and quietly left the ordnance prison.

Wanyan Zonggan felt that he estimated that there were some problems, could he really hold it up in three to five years?
