Early the next morning, Bai Chong came to report that the artillery of the Daifuku ship was successfully equipped!

After experiments, the cannon can achieve the expected power on the ship, and at the same time, Yu Jin and others also developed a way to protect the bronze cannon from the erosion of seawater, which is also very simple - the cannon is equipped with four wheels, and when not in use, it is pushed into the cabin to close the muzzle of the gun!

It's a bit stupid, but it's effective.

After listening to Bai Chong's words, I ordered: "The Peacock Dynasty has been occupied by Guishan, and I want to recapture the Kunlun South Peninsula from Guishan as soon as possible!" In order to increase the chances of victory and reduce the casualties of our Great Qin soldiers, it is necessary to speed up the progress of the construction of the Great Fu Ship. How many Daifuku ships can be built at the same time in Langya Port now? ”

Bai Chong thought about it carefully and arched his hand: "Back to Your Majesty, there are enough craftsmen to build it, and the key problem is rolling steel." Tiewu has selected a site to build an iron-smelting workshop in Langya Port, and there is no shortage of iron ore, but it is not a one-time effort to build a workshop, and it will take a year at the earliest. ”

"What about transporting it from Nanyang Iron Smelting Mansion?"

"It takes about half a year for the steel required for a ship to be transported to Langya Port."

I frowned, "How long did it take?" ”

Bai Chong was also a little helpless: "Dongfang Road originally only went to Linzi, and only opened up the road directly to Langya Port last year, and the planned cement road could not be completed for a long time, and there was too much shortage of ore!" At present, less than 200 miles of Dongfang Road are paved with concrete roads. ”

I nodded, it seems that it is unlikely that I want to build a Daifuku ship on a large scale as soon as possible.

For the time being, there is one, plus the twelve ships on the Qinnan Peninsula are almost enough, but it may be necessary for the Ganquan Army to dispatch......

I retracted, "How is the steam engine in Yujin?" ”

Bai Chong smiled awkwardly: "There hasn't been any particularly big progress, he said that it was only the problem that His Majesty raised last time, and even half of it has not been solved until now." ”

I waved my hand: "Tell him to take some people out of the steam engine, there is no need to spend more energy on it." ”

At present, it is still unrealistic, and we can no longer waste money and food on it.

Don't look at the fact that there are only more than 200 people who study steam engines, I am afraid that 2,000 people who can provide them with a series of things such as parts, experimental structures, machine tools and equipment will not be able to stop it! And that's not even counting the food and drink of these people, and the houses of the people.

"Forget it, Meng He, go and call him over."

After a while, Yu Jin hurried over.

I told him about the postponement of the development of the steam engine, and Yu Jin had some regret on his face that he would be able to build it in two more days.

Looking at his expression, I smiled and said, "I told you a long time ago, this is not a temporary thing. You don't have to be frustrated, the development of the steam engine was stopped because there was another thing for you to do. ”

Yu Jin's eyes burst out with brilliance again.

"Your Majesty, please!"

I pulled out a blank piece of paper and picked up my pen again.

"This is a balloon sewn from cloth, which is equivalent to hollowing out a watermelon, leaving only the skin, with an opening at the bottom, and a stove hanging underneath, and the balloon can float up after it is lit. Then hang a hanging basket underneath, on which you can sit people, control the rise and fall of the hot air balloon through the intensity of the burning of the stove, and install a fan to control the front and back, left and right, understand? ”

The two of them have been taught physics and can roughly understand what it means, but there are still two things that they don't understand.

"Dare to ask Your Majesty, how can this so-called hot air balloon be raised? Is it just that stove? ”

I nodded: "The air inside the hot air balloon is heated and expanded, the density of hot air is less dense than cold air, and the same volume of hot air is lighter than cold air, so it can float up, just like ...... Bubbles in the water? The metaphor may not be appropriate, along the lines of that. ”

Yu Jin roughly understood, and continued to ask: "The second question is, how to make this fan?" ”

I redrew a new picture: "It's the simplest, a shaft in the middle, and a Z-shaped connecting rod, one end is hand-cranked, and the other is connected to the center of the three fan blades, and the three fan blades can be rotated by shaking the handle at this end, and the wind can be blown." ”

Bai Chong glanced up at Yinghua, who was gently shaking the fan......

I smiled: "How to say the wind blown by the fan, the simple point is that it is not a natural wind, it is more like the wind of a tornado, plus the sweat evaporates relatively quickly, it is easy to get dizzy, so it is more comfortable to fan up and down." ”

The two roughly understood.

I handed them the drawings: "Start moving as soon as possible, just use materials similar to Daifuku sails, and don't have to be too demanding about waterproofness." ”

Yu Jin was puzzled: "What if it rains?" ”

I teased, "You dare to float so high in the rain?" ”

Yu Jin patted his head: "The minister was confused for a while, and he forgot that high places are more likely to be hit by lightning." ”

"Okay, you guys go, after the test is successful, just make two first, don't be in a hurry to make it on a large scale, the structure is prone to problems after a long time, and then make it when needed."

"Yes!"

After the two of them left, I got up and paced to the map.

"Summoning Zhanghan."

After Zhang Han came, I told him about the plan for the Kunlun South Peninsula.

Finally, he said: "The time of my plan is to set out after the beginning of spring next year, and if Langya Port can build another Dafu ship, it would be best if there was one." When the time comes, another 5,000 people will be drawn out from the Ganquan army, and the Kunlun South Peninsula must be taken in one fell swoop! ”

Zhang Han nodded, and said in a deep voice: "So now we have to start preparing for war, all the soldiers who have been dispatched to supplement the Ganquan Army have not yet arrived at the Ganquan Battalion, and the newly replenished soldiers must be allowed to form combat effectiveness before being transferred!" ”

"Yes, there's a lot going on......"

"By the way, Your Majesty, what should I do over there in Guishuang?"

I sat down again: "Don't pay attention to him, just let Wang Jin hang him over there." No matter how smart Qiqiu was, it was impossible for Daqin to think that Daqin would attack the Kunlun South Peninsula from the sea! ”

I looked at Zhang Han: "So this matter must be absolutely strict, and no news must be leaked!" ”

"The minister understands!"

"By the way, I still have to talk to Feng Zai about this matter."

Zhang Han was stunned for a moment, and then arched his hand and said: "The minister obeys the order!" ”

Since the cabinet has been established and the first assistant has been established, it is not appropriate for such a military event to bypass Feng Zheng, I believe he is measured.

"In addition, what you said last time about letting the Qin army of the Jiuyuan Great Wall go to open up Kunlun, I have thought about it carefully." I pointed to the map and said, "First send 3,000 people here, name it Xiningyi, and engage in lake salt mining." ”

Zhang Han glanced at it and said on a whim: "The terrain here looks like a millipede." ”

I smiled, the place I was referring to is the current Xining, Xining is located in the upper reaches of the Huangshui River Valley Basin, guarding the traffic arteries in and out of the Qingcao Plateau, known as the throat of the sea, about 340 miles away from Xigu, an absolute strategic place, from the Han Dynasty began to set up Xiping Pavilion.
