"It's hard to build, it's harder to build than a red-coated cannon, and even the bearings of the car we're sitting in are harder to build than a red-coated cannon."

Yuan Ji nodded, "The spring is made of iron, and the wire is bent around to form a column. It must be extremely hard, otherwise it will not be able to recover its original shape, and it will not be able to bounce. But it's so hard, how can it be coiled into a circle? The iron is brittle and broken, too hard and unmoving. It is much more difficult to build a root spring than the bite gear in a self-striking bell than to build a root cannon barrel. ”

Fuquan said strangely: "It's so difficult to build, why are you building it, the seat is covered with a thick cushion, it's different?" ”

"The iron factory has been built, and the iron has to be sold."

Yuan Ji smiled, "Blades, armor, and cannons, how much steel can be consumed?" How many taels of silver can you earn? It's better to have two kitchen knives per household in the Qing Dynasty. The output of the iron factory still has to rely on the consumption of ships, buildings, and civilian consumables, and it is not much to rely on the imperial court to make guns and cannons. ”

"Ships, buildings?"

Fuquan was even more surprised, "This boat and house, with iron?" ”

"The ship is not good, the iron sheet is improvised, instead of the keel, the current steel is not pure, how to remove sulfur and how to oxygen, I don't know, I have to try.

The second is that the steel made now is like a spring, and the tensile strength and yield strength are not enough. I only know about carburizing, I don't know how carbon seeps in, how much is good, whether it's charcoal or charcoal, and diamonds are charcoal.

I'm asking the craftsman to give me a furnace to try, a test to test, a record to check, a record to compare. When the inspection instruments and inspection methods are perfected, the material test comparison can be accelerated.

A few formulas and catalysts are meaningless, to make steel, you have to establish a complete production, education and research system from scratch, and connect with the market, which can be profitable.

Only when it is advantageous can there be motivation, and only then can it be endless, constantly innovating and self-evolving.

The third is that the steel is too heavy, even if the fully sealed pontoon tank watertight compartment is used, the wind power of the sail pocket cannot be pushed, unless a new power is used. ”

Yuan Ji explained, "But there is no problem with buildings, especially military buildings, like keels, the walls of buildings can also be sandwiched with bamboo bars and steel bars, which are stronger, especially more resistant to artillery." ”

"Anti-artillery?" Fuquan listened to the book of heaven, and felt that he couldn't keep up with Yuan Ji's train of thought, but he felt that the ninth brother, who liked to talk nonsense since he was a child, seemed to be quite reasonable, and as for what the truth was, he didn't know.

Fu Quan is only sixteen years old, pretending to be old, and he is an ancient little turtle, so he has to deal with this number like the fake elites of later generations to deal with local tyrants, pulling a bunch of nouns that he doesn't know, bringing more English vocabulary to complicate simple things.

You don't need to understand it, you just don't need to understand it.

"Second brother doesn't want to think about it, nowadays this cannon is getting bigger and bigger, and Hongyi's ships are getting more and more."

Yuan Ji chuckled, "In the future, when we deal with people, we have to have a port." Our ship is parked in the port, Xiyi's ship can be managed, and we can't let people touch the port.

Then you have to build forts and erect cannons along the harbor. The open-air fort is not conducive to anti-artillery, the stone is the same as the city wall, the cannonball will collapse as soon as it hits, and the stones that collapse out of the sky are not less than the fire gun, and there is no reinforced concrete fortress building anti-artillery. I'll make one for you to see, and you'll understand. ”

"Since you came back from Fujian, you have become more and more concerned about maritime affairs."

Fuquan was slightly depressed, "The Zheng family's ship cannon is no worse than Hongyi." ”

"Gunboats are still a trivial matter, the key is that our feet are different." Motoyoshi said with a smile.

"Oh?"

Fuquan wondered, "The feet are different?" ”

"yes."

Yuan Ji nodded, raised a leg on the seat, and patted his boots, "We ride a lot of horses, and when we walk, there is a big ball between our legs, and we walk from side to side." I saw Shi Lang and the Zheng family sailors who were captive, all barefoot, with their thumbs open, like duck flippers, on the bumpy plank, as if walking on the ground. ”

"The northerners are good at horses, and the southerners are good at boats." Fuquan agrees that the Zheng family's gang has a set of boats, attacking Fujian and Zhejiang, and seeing the sky to kidnap and plunder the villagers, they are like widows, which makes people unguardable.

"But can we let the boat master hold it all the southerners?"

Yuan Ji said indifferently, "No matter how good the Nanren are, there is no reason to hand over all the sailors of the Qing Dynasty to the Nanren." Nowadays, the big port and the navy division are all in the south, there are ships and soldiers, where can the coast in the north not land? In case these people gather in the boat division, carry tens of thousands of soldiers and horses to sneak into the Bohai Sea, land from Zhigu Tianjin, and go straight to the Beijing division, I am afraid that when we reach the city, we will know that people are coming. ”

Fuquan was so shocked that he almost didn't stand up: "Zheng Jing dares to sneak attack the Beijing-Tianjin portal? ”

"I didn't say Zheng Jing, a dog who guards the household, so don't be afraid."

Yuan Ji shook his head and said, "I'm worried about Xiyi, but by this year, the Francophiles have officially occupied Luzon for a full hundred years. Ships, ports, and strongholds in Annam, Johor, Sriwijaya, Manraka, Niguo, Java, Tianzhu, and Xiyi have spread throughout the South Seas. Xiyi is getting closer and closer to us, or more than a hundred years ago, the Jiajing Dynasty of the former Ming Dynasty has already obtained a port in Haojing. ”

After a pause, he said, "Actually, Hongyi also occupied Zhoushan, Penghu, Kinmen, and Dayuan in the sea off Zhejiang, but they were driven out again, they have tried more than once, won't they try again in the future?" ”

Taiwan is now called "Dongning", which is the name of Zheng Jing after succeeding to the throne, and Zheng Chenggong was called "Dongdu" at the time, and he was a member before.

"Don't worry about Zheng Jing, worry about Xiyi?"

Fuquan admitted that what Xiao Jiu said made sense, but it was still incredible, the Zheng family water master was much bigger than any Spanish now, he glanced at Yuan Ji strangely, and asked, "You don't want to find trouble with Xiyi, Zheng family water master is troublesome enough." ”

"Not really."

Yuan Ji shook his head and said, "I want to find a piece of land in the land of our Longxing, open up a port, and form a sailor in the north." I plan to ask the emperor for a will, and open a port in the south of Shengjing near Bohai Bay. ”

"Open a port in Shengjing?"

Fuquan was stunned, "Where?" ”

"Port Arthur."

Yuan Ji said indifferently, "I think the place is very good, it doesn't freeze in winter, and the second brother and the emperor are blowing the wind!" ”

"Second brother is a little cold!"

Fu Quan glanced at Yuanji, picked up the chopsticks and put a small soup bag in his mouth, muttering, "I'm afraid of being frozen by you." ”

……

"Bang!"

In the hills and valleys of Mentougou, there was an earth-shattering explosion in the dense forest!

“… Oops my grass! ”

The mud and rocks sprayed out like a shock wave of sawdust, and behind the bunker, a group of people flipped on their backs, screaming again and again, followed by a crackling burst of mud and smashed down on their heads and faces, falling like rain.

Behind the bunkers formed by the piles of horizontal wooden stakes, there was a muffled grunt again.

Then, there was a click of wood rubbing and the crunch of branches breaking.

“… Tree, tree down! ”

"Run!"

"Run, squat... Lying on your stomach, lying inward! ”

A prince and a royal brother pouted their buttocks, supported their elbows on the ground, and crawled wildly on the ground with their heads and dirty faces, eight guards pounced and crawled to protect the two masters, and more than a dozen officials of the Mentougou explosives test site who were standing scattered also hid behind the bunker with their heads and buttocks.

"Fuck off!"

Fuquan's guards saw a goatee in soap clothes and wanted to lie down on Fu's body, got up and kicked the goatee out, and then immediately shrank on the ground with his head in his hands, and rolled behind the cover.

"Pop" is another crisp sound.

Yuan Ji, who was suffering from the mud and rocks, was shrinking on the ground behind the bunker, and saw a shiny pig's head coming out in front of him, and slapped it without saying a word, "I'm your mother, Hu Laoba, how much medicine did you put in it?" ”

There was a crackling and a burst of mud and stone and broken wood pieces smashed down, and he was angrily glaring at Hu Laoba, who was stunned, and at the same time hugged his head and shrank back.

"Nine... Ninth Master. ”

shook the dirt and sawdust on his head, pulled down the broken vine branches that were sticking to his face, and Hu Laoba, who was lying on the ground and looked up to reply, his fat face was full of confusion and puzzlement, "No... I didn't put much. ”

"How much is it that you didn't put in it?"

Yuan Ji also lay on the ground and raised his head and asked angrily, and slapped Hu Laoba's head again, "Fortunately, it's not a test gun, otherwise this crash master would have to return to his place, how much the hell did you put it?" ”

"Just... It's just ten pounds. ”

Hu Laoba lay on the ground, crossed his hands and made an oblique cross, "Ninth Master, I didn't put much money on the small one." ”

"Who are you getting, ten catties is this movement?"

Yuan Ji was even more angry, scolded before he was stunned, raised his head and looked around at the desert, "The tree didn't fall?" ”

“… Ninth Master, smashed down two, and one hung up. "A bold guard of Fuquan, always watching the movement outside the bunker.

"I'll go and blow up three trees?"

Yuan Ji squatted up with his hands and looked out, saw that the big tree he hugged fell down and crooked, and he lowered his head and slapped Hu Laoba's head, and said angrily, "You still dare to say ten catties?" ”

"Really... It's really ......."

Hu Laoba covered his painful head that was fanned, and the ninth master, who was blown up before meeting, had a tendency to go berserk, and said weakly, "The little one doesn't know if the cotton medicine is buried and fried." ”

"Cotton... Cotton medicine? Nitrocellulose? ”

Yuan Ji frowned, pondered, and muttered, "No, isn't nitrocellulose a propellant, how can this ghost be blown up?" ”

After a pause, he asked Hu Laoba again, "Just cotton medicine?" Didn't mix anything else? ”

"It's old yellow material, dyeing material, and those things." Hu Laoba responded, "Everything added is recorded." ”

"I'll look back."

Yuan Ji wiped his face, dirt in one hand, and scolded, "What the is this?" ”

“… Alas, Xiao Jiu. ”

Fuquan was supported by the two guards and sat on the ground, humming and chirping, leaning against the stake of the bunker, covering his blue head, and his face collapsed, "This is your big killer." ”

"How?"

Yuan Ji was smug again when he was asked, and turned sideways to ask Fuquan, "Amazing, right?" ”

Fuquan couldn't believe his unreliable brother anymore: "Are you really stable?" It's like thunder underground, how to use it. ”

"Look at what the second brother said, why is it unstable? Let the Criminal Department send me all the unlucky eggs that Gyeonggi Naoli wants to execute, and it will be faster to stabilize it. ”

Yuan Ji smiled mysteriously and praised Fuquan, "As for how to use it, second brother, you have a great talent for fortune telling." ”

"Huh?"

Fuquan blinked, confused.

"Second brother, I'm busy."

Yuan Ji didn't say anything else, but said to Fu Quan casually, "The person you brought, borrow me for two days?" ”

Fuquan glanced at Yuanji and nodded: "Okay." ”
