Spring is blooming, everything is recovering, and the fields are covered with green. Outside the camp on the northern outskirts of the capital, the withered grass in the test site has also grown new shoots.

Su Lu rolled up his sleeves, surrounded by a group of guards, and was looking at a military newspaper in his hand.

In the ninth year of Yuan He, Hua Xun broke 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 the Qin land and held the city of Liangzhou, most of the Qin army was sent home.

In the same month, Cao Hua broke through Liangzhou, captured and killed 96 Qin officials below Emperor Qin, and Emperor Qin committed suicide in the Liangzhou Governor's Mansion.

The state of Qin died.

Su Lu put away the fold, handed it to Changning next to him, and commanded:

"Cao Hua's destruction of the Qin State, this is a great achievement, the Ministry of War and the Ministry of Officials are lenient, and the reward will be rewarded."

Changning frowned slightly when he heard this, "Your Majesty said that the reward should be heavy, but General Cao Hua wrote that he did not want to be rewarded, and he only wanted to return to Beijing." ”

Su Lu said casually when he heard this: "Then transfer her back, the staff office is newly established, and there is just a place for her, and the martial arts hall also lacks a commander like her who has led the three armies, so she can talk about war examples to the students and expand their horizons." ”

Dani's voice sounded: "Lord Wang, this stone rail is still not successful, and the wooden wedge fixed after closing is not strong enough, and it will be damaged and durable if it is shaken slightly." ”

"Then use iron nails."

Su Lu said casually, walked to the middle of the test site, and saw a small section of stone track that had been laid, the gray-white track was about more than a meter wide, laid on the stone pillow, and it looked very firm.

Su Lu originally wanted to use rails, but there was very little iron, and the casting of iron armor and weapons was not enough, so where could it be used to lay rails.

I had to settle for the next best thing, using stone rails, there were quite a lot of stonemasons in the capital, and I found some stonemasons at random, and these stone rails and sleeper stones were created in a few days.

"Lord Wang, you can run a carriage on such a stone road, is it impossible?"

Qingfeng shouted.

He is also an official of the Ordnance Mansion now, and because there are not enough people, Dani asked him for him from the True Elder Dao.

Su Lu stepped on the stone rails and felt the solidity of the stone rails, the toughness was definitely much worse than the rails, but it was already the best material that could be selected now.

"This is a specially made car, not an ordinary carriage, how is the car you built?"

Dani tried the iron rod she had found, handed it to the craftsman next to her, and then replied:

"It's almost, but I can't go yet, the true yuan Taoist proposed to put the internal information conversion cabinet in, I thought that this car was running on the track, and it didn't need to leave the ground, and I haven't figured out how to get it yet."

Su Lu shook his head: "You're not right. ”

"The internal information conversion cabinet belongs to providing power, why can't it be used in the car, just change the force of pulling the wings to the force that pushes the car forward."

"I'll draw a set of conversion diagrams, and you can figure out how to make them."

Su Lu said, instructed the guards to bring paper and pencils, and drew the traction of the railway locomotive on the stone tracks piled up next to it, marked the approximate size, and handed it to Dani.

Dani looked at this picture and was a little puzzled, can this thing really move.

Qingfeng shouted, "Lord Wang, can this thing go?" I think it's dangerous, so let's try the method of bird swinging to drive the handlebars, and fan the wind backwards with big wings, so that the car can't run. ”

Su Lu was noncommittal about this, he could run, but like the birds, the speed was definitely not fast, Su Lu wanted to do an express train of thousands of miles a day, not a slow bird.

"Do it first, if you don't do it, how do you know if it's okay."

Dani put away the picture and began to think about what material to use to make it, after all, it is necessary to consider durability.

Although Qingfeng still had something to say, he looked at the unkind eyes of the guards around him, and swallowed back the words very wisely. These guards and the Ouchi guards are all brain-dead admirers of the prince, and they believe what the prince says.

So is Lord Wang.

Qingfeng was a little sullen, feeling that he had entered a big pit, how could something that was painted like that be possible to run.

Half a month later, the tractor was finally made.

It's just a wood version, the connecting rod and the wheel are all wood, except for the special gold used in the internal information conversion cabinet, the rest are made of wood.

The wooden wheels sat firmly on the stone rails, and the breeze scurried away, connecting the connecting wheels with the internal information conversion cabinet.

"Who's going to drive the car?"

Qingfeng jumped out of the car and asked with an unhappy face.

This car will definitely not be able to run, so he will not be the driver of this shame.

Changning stood up: "Lord Wang, let me come, I am light in weight and the burden on the car is small." ”

Su Lu nodded, "Be slow when injecting internal breath, don't be in a hurry, enter little by little, don't be too fast, this wooden car is not strong, and it is easy to be damaged." ”

Changning nodded, jumped out of the car, pressed his hand on the handle of the internal breath conversion cabinet, and put the internal breath in.

After a while, the driving rod of the internal information conversion cabinet will open forward, driving the connecting rod of the wooden car to move forward, the connecting rod turns half a circle, and the wheel is pulled forward to rotate half a circle, and the wooden car begins to move.

"It's moving!"

The tall and dark face was full of excitement, and the big voice shook the breeze next to him, and his face was as black as the bottom of the pot.

As the connecting rod moves back and forth, the wooden cart begins to run continuously, and the speed begins to increase slowly.

"Hey, run faster and faster."

Gao Dabao said excitedly, cheering, like a child who has found a new toy.

Qingfeng stared at the wooden car, his eyes flashed with surprise, he didn't expect this thing to really run, this wooden car is not simple.

The prince is really powerful!

Qingfeng secretly glanced at Su Lu, and saw Su Lu standing with his hands in his hands, just looking at the car, and sighed. The prince is really powerful, whatever he does will become anything, and if he continues like this, he will become the brain-dead admirer of the prince.

"The wooden cart is still not strong enough."

Su Lu's voice fell into Qingfeng's ears.

Qingfeng took two steps forward, half a body behind Su Lu, and spoke:

"No, we are looking for the best carpenter in the capital, and the wooden car made is also the best, strong enough."

"Wow"

The wooden cart that was speeding suddenly fell apart, and a connecting rod was disconnected from both ends and directly became several pieces.

Qingfeng looked at the wooden cart that gradually stopped dumbfounded, his face was full of astonishment, the eyes of the prince were really vicious, and if it was not firm enough, the car would be broken.

"This link is made of special gold."

Su Lu instructed Dani that this thing needs to be durable enough, so wood must not work, and it is still necessary to think of using metal.

Pingqi took the two Dingxiang guards into the test site and walked quickly in front of Su Lu.

"I've seen the prince."

The three of them saluted respectfully.

Su Lu took the towel handed over by Huzi, wiped his hands, and asked:

"The Governor of Ping Dadu has nothing to do but go to the Three Treasures Palace, saying, what happened to me this time?"

Pingqi laughed: "There are many things to do, and the number of times I come to you is less, but you have always been in my heart, and I dare not forget it." ”

"There is news from the front line of Luojiang, there is an inner line that has made a great contribution and obtained the defense map of Eastern Qi for us, just wait for your order, you will be able to destroy the Qi State, completely surround the Tang State and Southern Chu, and drive the Yingtes out of the Qi State."
