After drinking the soup, Qin Yun stretched his waist and sent Zhou Meiniang, who was pestering him, and walked straight to Tiangong Academy.

The Tiangong Academy is a place specially set up by Qin Yun to develop new weapons and equipment, and it is the highest military secret in Qiongzhou.

Anyone, not even him, must go through a strict identity check before they can enter.

The reason is very simple, the disguise technique of this world can still be done to the point of being fake, especially the human skin mask like Yue Guo.

That's why there is a rule of seven levels and twelve cards.

After passing through the level, Qin Yun entered a high wall.

At this time, Luban was experimenting with his Lianzhu machine gun, which had been used in the last battle of the dockyard.

Qin Yun also attaches great importance to this, after all, this thing is a serious heavy firepower, and now Qiongzhou can't see much effect.

But in the future, if it is placed on the steppe and plain to face the enemy's cavalry, this thing will be a great weapon of destruction.

Don't you see that as soon as the Ma Keqin machine gun came out, the heroic and warlike nomads became a kind people who could sing and dance?

"Master Lu, how's it going? Is water cooling ready? ”

Lu Ban looked melancholy: "Lord Wang, the water cooling thing you said is really easy to use, but it leaks, and if you use an iron pipe, the weight is too heavy and you can't move it at all." ”

"With bamboo pipes, it's not durable, but it worries me."

Qin Yun said with a smile: "Today, this king is here to help you solve this matter." ”

"Really?"

Qin Yun said to Lu Ban: "Call Master Shangzhu!" ”

Qin Yun smiled: "He can use it too." ”

After a while, the cast iron ridge came in the dust.

"Lord Wang, what's the matter?"

Qin Yun then asked, "How is the progress of the steam engine?" ”

Cast Iron Ridge: "According to the prince's assumption, the road is definitely right, but the air tightness cannot meet the requirements, resulting in a lot of steam energy. ”

"However, the iron ship frame has been completed, and there are some difficulties in the pure iron at present, but we have managed to overcome the difficulties, and the old man's idea is still to refit."

"There was also an unfinished Shenlong ship in the dock before, and the main structure was placed elsewhere because it was being decorated, and it was not burned. We can replace the keel of this big ship with steel, and change the original planks to iron wrapping. ”

"In this way, not only can we quickly build large ships, but we can also match the current first-generation steam engine."

"Of course, after the transformation of the big ship, it can only be equivalent to a medium ship."

Qin Yun said with a smile: "Very good, what this king wants at the moment is combat power, and the most urgent thing for us now is to kill this group of pirates and get back what belongs to us." Only in this way can we develop better. ”

Cast Tieling sighed: "However, I can't meet the requirements for air tightness for a long time!" ”

Qin Yun smiled: "Master Lu, do you remember that I asked you to demarcate the rubber forest before?" ”

"Today, I'm going to take you to rubber tapping."

"Rubber?"

Qin Yun said: "That's right, this is a natural industrial material, with its arbitrary plasticity, it can not only solve the problem of heat dissipation of this Lianzhu machine gun, but also solve the air tightness of the steam engine pipeline transmission." ”

"Let's go, go up the hill!"

The crowd rejoiced.

In the wild rubber forest, Qin Yun led people to teach them how to tap rubber.

"You see, a tree like this that has grown for twenty or thirty years is just right to tap rubber, remember that you only take a small bucket from each tree, and you can continue to take it next year."

"Lord Wang, is this sap really useful?"

"Don't worry, when did this king deceive you? Moreover, this rubber has another use, that is, it can be used to make tires. ”

"Wooden wheels are perishable and bumpy when exposed to water, but if you make a tire out of them, you can inflate them to absorb shock."

"Even if it's just wrapped in a wagon."

"With tires, the bicycle that Ben Wang mentioned before can also be tried to make."

"That's good, then I'll cut a little more!"

"Don't be in a hurry, take your time, and boil to remove impurities when you go back."

……

In this way, three days passed in a flash, and Qin Yun led people to cut down the wild oak trees in half of the mountain, and then stopped.

"Yang Yong!"

"Humble duty!"

"Pass the order to go down and clear 10,000 acres of mountainous land to plant and transplant rubber trees."

"No!"

Qin Yun knew that this thing would become a real strategic resource in the future.

Many people know that the flashpoint of the Industrial Revolution was the steam engine, but many people don't know that the original steam engine was actually discarded due to its low energy conversion rate.

It wasn't until after the improvement and the rise of the rubber industry that the steam engine really went to the masses.

Qin Yun was already looking forward to the birth of the first steam engine in Qiongzhou.

With the rubber, the rubber pipe was formed, and after solving the airtight problem of the air valve, Qin Yun no longer paid attention to the matter on the side of the workshop.

He knew that everything was ready, and that the rest was left to time and the craftsmen.

In the past few days, Qin Yun has been busy, but he has left Yue Qing behind.

However, she didn't mind, she followed Han Jiangxue to visit Qiong everywhere and saw the new atmosphere everywhere.

The construction of roads, the repair of embankments, the improvement of farmland to farmland, the whole Qiongzhou is a thriving attitude.

As a woman she is stingy, but as a king, she is very insightful.

Qiongzhou is such a scene, in another three or five years, no, in a year or two, the national strength will directly boil the rhythm.

"Qin Yun, Qin Yun, I didn't expect that you are also a good hand at governing the country."

"Sister Han, I heard that you stayed to be Qin Yun's guest, why is this? It's not for that man! ”

Han Jiangxue: "You should take it." How's it going, have you had a good time these days? ”

Yue Qing: "Happy is happy, but I want to go to the arsenal!" ”

Han Jiangxue was embarrassed: "I can't call the shots about this!" ”

"Huh, stingy!"

"Who do you say is stingy?"

Qin Yun strode over, Han Jiangxue's eyebrows lit up, and he could see that he was very happy in his heart, it was the eyes of his lover.

Yue Qing: "What's wrong with saying you're stingy?" Didn't you say that you would sell me weapons to Yue Guo? What about weapons? ”

Qin Yun said: "I've been busy these days, so I don't have time." I'll take you to see it now! ”

"Really? You're not afraid that I'll steal the school? ”

Qin Yun laughed: "If you can understand and learn, you can go!" ”

Yue Qing: "Don't look down on people, I'm a genius!" ”

"Where are you going!"

"This way!"

Qin Yun pointed in a direction, and Yue Qing walked over with a big grin.

Qin Yun came to Han Jiangxue, who was left behind, and just happened to the softness of her palm.

"Dinner together in the evening?"

Han Jiangxue: "You won't accompany your little wife and princess?" I heard that Zhou Meiniang was beaten, who beat her? ”

"Don't mention it, Yue Qing's girl's hand, if she knew about the relationship between you and me, maybe she would even beat you."

Qin Yun said angrily.

Han Jiangxue blinked: "Is she really the King of Yue?" ”

"It's true!"

Obviously, Qin Yun told Han Jiang Xue Yueqing's identity.

"What are your uncles and sisters-in-law muttering?"

Uncle and sister-in-law?

Han Jiangxue smiled: "Uncle Jiu, it's not appropriate for you to squeeze your sister-in-law's hand!" ”

Qin Yun immediately smiled and said, "Sister-in-law, you are so good-looking!" ”

"Phew!"

The two of them parted and stepped forward.

Yue Qinghu looked at the two suspiciously.

"You two grinding and chirping, where is the arsenal?"

Qin Yun pointed to a mountain bag in front of him.

Yue Qing: "You're fooling me?" ”

Qin Yun walked to the side and opened a tombstone thing.

Hearing a boom, a stone door opened, and Yue Qing's eyes widened.

"This ...... Is there a mechanism for this? ”

Qin Yun smiled: "Don't forget, I have a group of inheritors of the Mo family's tricks here. ”

"Let's go, don't be verbose."

"Hmph, I want this thing too, you can rest assured that my country is having money." Yue Qing walked in with his head held high.

After entering, Yue Qing was directly shocked.

Where is this a small mountain bag, this is clearly a natural secret place.

After passing through the narrow road, Yue Qing saw the prototype of a small mountain village here.

Not far away, black smoke and white smoke were rising from the chimney.

Truckloads of iron ore were pushed straight out of the ground and slid onto the rails.

The workers were sweating like rain, some were digging rocks, some were pouring sand, and they didn't know what they were doing, and some were making iron and striking iron.

Soon, Yue Qing's gaze was attracted by a long, black, and thick cannon.

"What's that, it's a big one!"

Han Jiangxue glanced at him on the side.

"This is a cannon!"

"It is by pulling the bolt to activate the shell from the barrel, and the shell is fired to cause effective damage to the enemy."

"How much?"

Qin Yun scratched the back of his head and thought about how to set the price.

Han Jiangxue on the side said with a smile: "This cannon is much stronger than the mountain cannon installed by the pirates, Princess Yue, when we were on Haitang Island, you also heard that the pirates' cannons are one million and twenty-one." ”

"With your relationship with the prince, you can pay 800,000 yuan."

"It's not expensive, give me thirty first, no, fifty!"

"Why are you looking at me like that? Yue Guo has done nothing but make money over the years, the treasury is almost full, and my mother is still wondering if to exempt fishermen from fishing tax......"

Qin Yun and Han Jiangxue glanced at each other, local tyrants!

"Princess Qingqing, I think it's necessary for us to talk about another big business."

Qin Yun stepped forward with a smile.

"What are you doing? You're laughing so lewdly, don't come here......"
