"What kind of road are you building?" King Qin asked.

"Your Majesty, this is the national highway and highway that Mr. Qin asked us to build." The lieutenant said respectfully.

"What is a national highway, what is a highway." King Qin asked.

"Seven zhang wide, the north and south are divided into national highways, and the north and south are separated by two lanes, one only goes south, one only goes north, it is the highway." The lieutenant said.

"Oh, show the widow." King Qin said after listening.

"Whoa." The captain stood aside, and Zhao Gao led the way.

Come to the repaired highway. King Qin stepped on it vigorously, and then said, "This road is stronger than the galloping road." What is this black thing? King Qin asked.

"Your Majesty, this is rubble mixed with asphalt." The lieutenant said respectfully.

"Asphalt? What is this? King Qin asked.

"Your Majesty, this asphalt is a waste residue extracted from the oil of the fierce fire. Mr. Qin said that the road surface is extremely smooth when the road is built with this material. And it is not easy to be damaged. The lieutenant said.

"Go on." King Qin listened with relish.

"Thank you, your king, please see. This highway, the highway, is slightly higher in the middle than on both sides, making it easy to walk on the water. There are drainage facilities on both sides of the road. So when it rains. There is no standing water on the road. The lieutenant paused.

"Highway, lanes in both directions are all separated. Go in just one direction. So, you can keep a quick follow-up. The lieutenant said, pointing to the highway. King Qin nodded.

"This ・・・・・," the lieutenant said again. But seeing that King Qin waved his hand to stop him from speaking, he also stepped aside.

"Such a good road needs to be tested." King Qin said.

"Come on, drive a few wagons, and give the widow a try." The King of Qin ordered.

"Whoa." Several officers replied.

In a few moments, several carriages came galloping in. When not on the highway, the bumpy carriage felt like it was about to fall apart. Ding Ling screamed. King Qin watched silently, and after getting on the highway, the bumpy state of the car was gone. Ding Ling's squealing voice disappeared. Instead, there was the crisp sound of horses' hooves. The speed of the car is also very fast. After a while, it ran to a certain point. King Qin nodded.

After a few carriages had run away, they immediately turned back. "Phew" With the officer's shout, the carriage stopped steadily on the highway.

Several officers dismounted and quickly ran to the King of Qin. Salute on one knee.

"Your Majesty, this road is indeed smooth and abnormal. The horses galloped on top as if they were flat. Lightning-fast. The officer said happily.

"Oh, the widow will try it too. Zhao Gao, you come too. King Qin said.

King Qin flew into the carriage with a brisk stride, and Zhao Gao also got into the carriage neatly.

The carriage ran out quickly, and several guards wearing bronze masks also rode out.

"Okay, okay." King Qin said happily.

Zhao Gao grabbed the handle of the car tightly. Because it's too fast. But it was so stable, Zhao Gao looked a little frightened.

"Drive, snap" A crisp leather whip sped up the speed of the carriage. The carriage whizzed by. King Qin was very happy.

"Zhao Gao, the road is extremely flat, and the car is not bumpy at all. It's smooth. King Qin said as he drove.

"If the widow wants to build it in the future, he must build such a road. The widow swept away the six kingdoms. All the days are built with such roads. The widow can drive and sleep peacefully on this carriage and horse. Hahaha. King Qin said with a smile.

"Drive." King Qin waved the leather whip in his hand again and sped up.

"Oh my God. This is the chain of your making. Shangwen went to the place where the blacksmith had made to inspect the chain he had made, but what he saw was something like a tank track that was one size smaller. Holding this nondescript thing back and forth in his hand over and over again. Shang Wen had a feeling that he wanted to cry and couldn't cry.

"Indeed, sir, we did what you asked." The blacksmith whispered.

"I, I asked you to make it as small as possible, but what you want to build is so big, how can I use it." Shang Wen said, holding the chain in his hand.

"And this gear, you didn't even think about it, can such a big gear enter the eye of this chain, this one goes in, and the next one goes." Shang Wen said with some anger.

"We didn't expect that." The blacksmith said, scratching the back of his head.

"Redo, redo." Shang Wen said impatiently.

"I'll get it later." Shang Wen walked out of the blacksmith's shed, but thought of the place that was still useful, and couldn't blindly talk about people, so he returned.

Seeing Shang Wen leave and come back, he thought that he had something to entrust, and the blacksmith hurriedly arched his hand and said, "I don't know, what else does Mr. have to order." ”

Before Shang Wen could speak, he was asked by the blacksmith.

"No, nothing." Shang Wen was a little embarrassed.

"I just want to say, you do a good job, as long as you make what I want, the reward will be indispensable. And good wine and good meat. Shang Wen finished with some incoherence.

The blacksmiths were caught off guard when they heard this. Don't know what to do. It was too sudden. But fortunately, someone woke up in time. Hurriedly said: "Mr. Xie Qin." "Mr. Xie Qin." Everyone said it one after another. Shang Wen felt a little cold. He smiled awkwardly and ran out.

"Whew." Shang Wen exhaled heavily, feeling a little depressed. I finally wanted to raise someone's salary, give some rewards or something, but I didn't expect to make myself nondescript.

"Ugh." Shang Wen sighed and went to the place where the carpenters had been conducting.

"Come to the carpenter's place. Shang Wen saw a carpenter working a plank. The planks are already made very smooth. From time to time, some people measure it with their fingers or touch it. Is it flat.

It seems that the master carpenters are working hard. And its professionalism is very worthy of recognition. Shang Wen thought in his heart. Silently applaud this professionalism.

"Mr. Qin is here." A carpenter's head took the initiative to greet him.

"Oh, I'm just here to see." Shang Wen didn't know what the carpenter's name was, so he had to vaguely agree to go over.

"I've pretty much done what you said. You come and see. is not in line with your requirements. "I want to ask Shang Wen to take a look.

"Okay, okay." Shang Wen followed.

"It's a good thing." Shang Wen said, looking at the planks that had been planed into a thin layer.

"Mr. Qin, please take a look. When the two planks are joined together, they are firmly joined together. Even if you try to break it, you can't tell it. The carpenter said with a sense of accomplishment.

Shang Wen took a closer look, and it was really this kind of approach, which was very ingenious like the old man. And it has to be disassembled according to a certain strength and direction. The wooden pin should also be taken out before dismantling. It's a wonderful workmanship. Shang Wen had to admire in his heart.

It turns out that the ancient carpentry work has reached such a point, if you follow your own ideas, then the manufacture of weapons will definitely not be a problem.
