Spring is warm, flowers are blooming, everything is revived, and the fields are covered with green. Outside the camp in the northern suburbs of Beijing, the dead grass in the test site has also sprouted new shoots.
Su Lu rolled up his sleeves, surrounded by a group of guards, and was reading a military report in his hand.
In the ninth year of Yuanhe, Huaxun defeated Shule.
In the spring of the following year, the Qin army in Liangzhou mutinied and most of them surrendered. Except for a few who defended Qin and defended Liangzhou city, most of the Qin army was sent home.
Just last month, Cao Hua broke into Liangzhou and captured and killed 96 officials of the Qin State below the Qin Emperor. The Qin Emperor committed suicide in the Liangzhou Governor's Mansion.
Qin fell.
Su Lu put away the folder, handed it to Chang Ning next to him, and gave instructions:
"Cao Hua destroyed the Qin State. This is a great achievement. I will discuss it with the Ministry of War and the Ministry of Civil Affairs and reward him accordingly."
Chang Ning frowned slightly when he heard this, "Your Majesty said that the reward should be heavy, but General Cao Hua has written a letter saying that he does not want to receive the reward and only wants to return to the capital."
Hearing this, Su Lu said casually: "Then just transfer her back. The General Staff Office has been newly established, and there is just a place for her to use it. The Martial Arts Hall also lacks a commander-in-chief like her who has led the three armies, so she can be used for the students."
Talk about war examples and expand their horizons."
Dani's voice sounded: "Your Majesty, this stone rail is still not finished. The wooden wedges fixed after closing are not strong enough. They will be damaged by a slight vibration and are not durable."
"Then use iron nails."
Su Lu said casually, walked to the middle of the test site, and saw a short section of stone track that had been laid. The gray-white track was about one meter wide, and was laid on stone pillows. It looked very solid.
Su Lu originally wanted to use railroad tracks, but there was very little iron, and cast iron armor and weapons were not enough. How could it be used to lay railroad tracks.
The next best thing was to use stone rails. There were many stonemasons in the capital, so I randomly found some stonemasons and built these stone rails and sleepers in a few days.
"My lord, it's impossible for a carriage to run on such a stone road, right?"
Qingfeng shouted.
He is now also an official in the Ordnance Department. Because there are not enough people, Dani asked him to come over from Zhenyuan Laodao.
Su Lu stepped on the stone rails and felt how solid they were. The toughness was certainly much worse than that of railroad rails, but it was already the best material available.
"This is a specially built car, not an ordinary carriage. How is the car you built, Dani?"
Dani tried the iron rod she found and gave it to the craftsman next to her to bend it, and then she answered:
"It's almost done, but we can't leave yet. Taoist Master Zhenyuan proposed to install the inner energy conversion cabinet. I thought that the car runs on the track and does not need to leave the ground. I haven't figured out how to do it yet."
Su Lu shook his head: "Your idea is wrong."
"The internal information conversion cabinet provides power, why can't it be used in a car? Just change the force of pulling the wings into the force of pushing the car forward."
"I'll draw a set of conversion diagrams, and you guys can figure out how to make them."
As Su Lu spoke, he asked the guards to bring a pen and paper, and drew the traction of the railway locomotive on the stone rails piled nearby. He marked the approximate dimensions and handed it to Dani.
Dani looked at this picture and was a little confused. Can this thing really move?
Qingfeng shouted: "Your Majesty, can this thing move? I think it is dangerous. We might as well try the waving method of a flying bird to drive the handlebars of the car. The big wings will fan the wind backwards, and the car will start running."
Su Lu did not comment on this. He could run, but like a flying bird, he would definitely not be able to go fast. Su Lu wanted to be a fast train that could travel thousands of miles a day, not a slow flying bird.
"Let's do it first. How will you know if it will work until you make it?"
Dani put away the pictures and began to think about what materials to use. After all, durability must be considered.
Although Qingfeng still had something to say, he looked at the unkind looks of the surrounding guards and wisely swallowed the rest of his words. These imperial guards and Ouchi guards were all brainless admirers of the prince, and they would believe whatever the prince said.
Lord Wang too.
Qingfeng was a little unhappy, feeling like he had fallen into a big pit. How could something drawn like that move around?
Half a month later, the tractor was finally built.
But it's a wooden version, the connecting rods and wheels are all made of wood, except for the inner conversion cabinet which is made of special gold, the rest are made of wood.
The wheels of the wooden cart sat firmly on the stone rails, and the breeze rushed up to connect the connecting wheel with the inner energy conversion cabinet.
"Who's going to start this car?"
Qingfeng jumped out of the car and asked with an unhappy look on his face.
This car will definitely not run, and he will not be such a disgraceful driver.
Chang Ning stood up: "Your Majesty, let me do it. I am light and will put little burden on the car."
Su Lu nodded, "When injecting the inner breath, be slow, don't be anxious, inject it little by little, don't go too fast, this wooden cart is not strong and can be easily damaged."
Changning nodded, jumped into the car, pressed his hand on the handle of the inner breath conversion cabinet, and put the inner breath inside.
After a while, the driving rod on the internal information conversion cabinet opened and acted forward, driving the connecting rod of the wooden cart to move forward. The connecting rod turned half a circle and pulled the wheel forward half a circle, and the wooden cart began to move.
"Moved!"
Gao Dabao's dark face was full of excitement, and his loud voice made Qingfeng next to him turn as black as the bottom of a pot.
As the connecting rod moves back and forth, the wooden cart begins to run continuously, and the speed begins to slowly increase.
"Hey, run faster and faster."
Gao Dabao said excitedly, cheering for joy, just like a child who discovered a new toy.
Qingfeng stared at the wooden car, his eyes flashing with surprise. He didn't expect this thing to actually run. This wooden car is not simple.
Your Majesty is so awesome!
Qingfeng glanced at Su Lu secretly, and saw Su Lu standing with his hands behind his back, just looking at the car, and sighed. The prince is really powerful, and he can achieve anything he wants. If he continues like this, he will become his stupid admirer
.
"The wooden cart is still not strong enough."
Su Lu's voice fell on Qingfeng's ears.
Qingfeng took two steps forward, half a body behind Su Lu, and said:
"No, we are looking for the best carpenters in the capital, and the wooden carts they make are also the best and strong enough."
"Wow"
The wooden cart that was running suddenly fell apart, and a connecting rod was disconnected from both ends and broke into several pieces.
Qingfeng stared at the wooden cart that was gradually stopping with his mouth open, his face full of astonishment. The prince's eyes were really vicious. If it wasn't strong enough, the cart would slip and break.
"This connecting rod should be made of special gold."
Su Lu told Dani that this thing needs to be durable enough, so wood will definitely not work, and we must find a way to use metal.
Ping Qi led two Dingxiang guards into the testing ground and quickly walked to Su Lu.
"I have met the prince."
The three of them saluted respectfully.
Su Lu took the towel handed over by Hu Zi, wiped his hands, and asked:
"Master Ping doesn't come to the Three Treasures Hall for anything. Tell me, what happened to you this time?"
Ping Qi laughed: "General, I have a lot of things to do, so I don't come to you often. However, Your Majesty, you are always in my heart, and I don't dare or forget."
"There is news from the Luojiang front line that an insider has made great contributions and obtained the defense map of Dong Qi for us. As long as you give the order, we can destroy the Qi State, completely surround the Tang State and Nan Chu, and
