"Firstly, there is a famine in the northwest and there is no peace there. Secondly, the border of Qianzhou..."

As Xiao Jiayuan spoke, he tapped his finger on Qianzhou.

"This is the junction between us and the Nanzhao Kingdom. This place has always been the most chaotic. Not to mention the mixed dragons and fish, there are Jianghu forces, local officials' forces, chamber of commerce forces, and Nanzhao people who do business here. Several forces The forces are gathered together and complicated. Every year the imperial court sends special envoys there, and every year either the envoys die violently or collude with Qianzhou Hang. If he wants to establish a fiefdom, the emperor will most likely decide it here."

Gu Luo looked at the location of Qianzhou on the map, "He wants to use the situation in Qianzhou to hold back the prince, so that the prince can protect himself, have no time to pay attention to the court's movements, and have no power to rebel? But since Qianzhou is in such chaos, he has another idea. With a good reputation for treating the former prince’s orphans well, how could he dare to blatantly send the prince to Qianzhou?”

Xiao Jiayuan sneered and said: "The former prince is brave and good at fighting. He once fought against Nanzhao. The former prince was stationed in Qianzhou. It's just an excuse. He can just make up some random excuse and say that the land is the former prince's wish place or something else. , However, if we really choose this place, we won’t really have no way out.”

Qianzhou not only has these chaotic forces, but also the forces that Yu Yan has carefully cultivated over the years.

Otherwise, Yu Yan has been going crazy these years to grab money whenever he sees it!

In the past, in order to grab money, I even split Yunhaiju's profit 50-50 with Gu Luo, which was shameless.

"Sister-in-law, sister-in-law, come and see! Come and see! Come and see!"

While he was talking, Yu Huan ran in from outside shouting.

Wearing a jacket in spring, she was sweating all over, her cheeks were red, her hair was sticking to her forehead, she was holding on to the door frame and gasping, "Sister-in-law, this is incredible, go and see what Gu Heng has done, he modified it The carriage is really not bumpy at all!"

Yu Huan's bright eyes were shining as she greeted Gu Luo.

We have basically finished discussing the matter with Xiao Jiayuan. What happens next depends on what happens in the palace.

Gu Luo took Yu Huan to find Gu Heng, and Xiao Jiayuan followed behind him dragging his lazy body.

In the backyard of Prince Anbo's Mansion, Yu Yan renovated a small racecourse. When they passed by, Changle was driving a large carriage galloping on the racecourse.

"Stop, stop, let my sister-in-law sit on it and feel it!"

Yu Huan was so excited that he took Gu Luo to his seat and ran towards the carriage, shouting as he ran.

Gu Heng was afraid that she would hit her, so he quickly chased after her and held her down, "Why are you running? That horse can't stop at once. Your heads can withstand its kicks. If you stand here honestly, even if you don't get kicked by the horse, you know Is it likely to cause sudden death if you breathe in a lot of dust?"

The dignified little princess was not upset even after being scolded. She smiled and let Gu Heng hold her hand. Her eyes almost disappeared from laughter, "I still want to ride in the carriage."

Gu Heng hummed, took out a small red flag from his arms, and waved it towards Chang Le. After a moment, Chang Le slowed down the carriage and gradually stopped. It stopped right in front of Gu Heng.

Sitting on the carriage, Chang Le's face was full of excitement, which was no less than Yu Huan's. "That's good. I don't feel the bumps in the carriage even when I speed up. When the stones come, I'll try throwing some more stones."

Xiao Jiayuan looked confused, "What are you doing?"

Gu Luo heard Yu Huan murmur early in the morning that Gu Heng had modified the carriage. He lowered his eyes and looked at the wheels. The original wooden wheels were covered with a layer of animal skin.

"Can this animal skin withstand such wear and tear?" Gu Luo squatted on the wheel and touched it. When he squeezed it, he found that the inside of the animal skin was a little soft.

Gu Heng smiled and said: "The animal skin will definitely not be able to withstand the grinding when it is attached to the wheel. However, the animal skin has been soaked in oil, and its wear resistance has been greatly improved. It is also filled with some bamboo strips, which have also been soaked in oil.

It's durable, and when the wheels roll, the ground will not squeeze the animal skin directly onto the wood of the wheels, and it has a buffering effect."

Xiao Jiayuan was confused, but that didn't stop him from thinking that Gu Heng was capable.

He gave a thumbs up and said: "With this, can you stop being upset?"

Gu Heng pointed to the bottom of the car, "There are things added inside, but the most effective thing is still the one."

Xiao Jiayuan bent over and looked over, and Gu Luo also looked over where Gu Heng was pointing.

Good guy!

Isn't this just adding two springs to the position of the bearing at the bottom of the car?

A spring made of black iron, about as thick as a thumb, is fixed on a bearing. When the carriage bumps, the spring bounces, which naturally slows down the carriage's response to ground vibrations.

Gu Luo stood up and looked at her brother with a confused expression, "Spring?"

Gu Heng raised his little face with a pure and innocent expression, "Sister, what is a spring? What are you talking about?"

Gu Luo raised her eyebrows and looked at him, "I don't know what a spring is. Where did you get this thing from?"

Xiao Jiayuan finished studying the spring, got out from under the car, patted the dust on his body, and said before Gu Heng could speak: "This is inspired by the serial crossbow. This kind of spring is installed on the serial crossbow, but it's just that

It is much smaller than this and can slow down the backward impact on the archer when the repeating crossbow is fired."

Gu Heng immediately said: "Yes, that's true."

He smiled with a sly look on his face, and after speaking, he turned to Gu Luo very sternly: "Sister, what is a spring? Where did you hear this name? It's so strange~"

Gu Luo:......

Another day when I suspected that my brother had traveled through time but had no evidence.

While they were talking, two boys in the house pushed a cart of stones over in a wheelbarrow. The stones were of different sizes, the small one was as big as a thumb, and the big one was as big as Xiao Jiayuan's fist. Under Gu Heng's command, the boys pushed a cart of stones over.

The stones from the cart were scattered on the racecourse.

"Sister-in-law, come on, let's get in the car and give it a try. It's going to be interesting. When the carriage is running, the carriage bumps and bumps without hitting the buttocks at all. Instead, it trembles and trembles. It's very interesting."

Yu Huan's admiration for Gu Heng surpassed that of her brother, and she was so obsessed with him.

Gu Luo rubbed Yu Huan's little head and got into the car.

Over there, Gu Heng scattered the stones, took out a green flag from his arms, and waved it at Chang Le. Chang Le received the order and drove off, heading specifically for the place where there were stones, controlling the speed at times faster and slower.

Although it is not as comfortable as a modern vehicle, the carriage is covered with thick mattresses, coupled with Gu Heng's shock absorption device, and sure enough, when the carriage runs, the interior of the carriage trembles and trembles like a jumping kangaroo in a modern amusement park.

.

No wonder Yu Huan is so excited.

What child doesn't like the playground?

"I have only modified this car now, mainly because there are not many black irons sold outside. I found several blacksmith shops to get these two. However, fortunately, this car is big enough for people who need to ride in it.

not much."

There are no female relatives in Yuyan Mansion.

The people riding in the carriage were Gu Luo, Yu Huan, Gu Heng, and a nanny who took care of Yu Huan all year round.
