On the top of the mountain, roller skating groups began to form houses. This workshop was not like ordinary workshops. In Gu Qing's idea, he fenced the entire mountain and built a fort-style factory. The entire mountain was connected from the inside, and this factory had to build a lot of things.

Li Chunfeng hurried to find Gu Qing, "It's considered to be finding you. I have asked me to wait for you for a long time, but it's a waste of time."

"What's the matter with Master Li?" Gu Qing was puzzled, and Li Chunfeng was already panting.

"Geometric algorithm!" Li Chunfeng said, "Don't tell me that you have forgotten! You promised that day."

"I really forgot." Gu Qing said.

"You!" Li Chunfeng wanted to speak but stopped, "As expected..."

"Hahaha, Master Li, don't be anxious." Gu Qing persuaded, "I remember now that I'm thinking about it again. This geometric algorithm is very complicated and I can't explain it clearly for a while. Let's start with the most basic ones."

"The most basic?" Li Chunfeng sneered, "I still need to start learning from the most basic level? Gu Qing, do you look down on me in mathematics?"

"Where there, there is," Gu Qing said with a smile, "Then let's start from the most basic one."

"..." Li Chunfeng thought to himself, why is it the most basic?

Gu Qing found an unwritten piece of paper from the pile of drawings next to the construction site and drew an isosceles triangle with charcoal strokes. "Master Li, you should know what this is."

"Isn't this a triangle?" Li Chunfeng disagreed.

Gu Qing said again, "In fact, there are several types of triangles, but they will never be separated from each other. The three corners of the three are combined into a semicircle."

"Is this true?" Li Chunfeng was puzzled.

"Master Li might as well give it a try." Gu Qing said with a smile, leaving Li Chunfeng with this problem to continue watching the construction of the factory.

Li Chunfeng looked at the triangle in front of him. The three corners together turned into a semicircle. Is this true? As he said that, he drew a very neat triangle again, carefully tearing off the three corners, splicing them together, and his eyes suddenly became straight! It was really a semicircle.

After experimenting countless times, Li Chunfeng breathed rapidly. As long as he drew a neat triangle and then spliced ​​the three corners together, they were all a semicircle. He studied it like he had discovered a new continent and had never noticed such a wonderful thing.

When he looked up, he saw that Gu Qing was no longer here. He came to the office of the bookstore with anxious heart. Li Chunfeng kept drawing triangles with Gu Qing's charcoal brush, and his eyes changed very often. Why didn't he discover this mystery for so many years? The rules of triangles were deduced in his mind, and a wonderful feeling lingered in his heart.

He gave Zhang Jie a few instructions, focusing on safety and tools, and never let the workers do it recklessly. Gu Qing and Yang Sheng walked to the entrance of the village together. The forest here was full of green, and it was the season when everything was revived. He came to an ambush point in the Qing Gang to look from afar, "The Zheng family still sent a spy liner. Is this news reliable?"

"It was their retainers who said it." Yang Sheng said.

Gu Qing took the mask and walked forward. The members of the Qing Gang in front of him all had masks on their faces and said to them, "Brothers have suffered, and they have suffered all these days."

Zhang Yugong looked at the mask style and heard the familiar voices and hurriedly bowed, "See lord!"

"See lord!" The remaining dozens of members of the Qing Gang also saluted Gu Qing.

Lord? Is this title also used in the Tang Dynasty? Gu Qing took out a small piece of silver cake and handed it to Zhang Yugong, "Don't save it when you drink with your brothers."

"Thank you lord!" Zhang Yugong said, the person in front of him was Gu Qing, the decision maker of the entire Qing Gang, and the financial backer and founder of the Qing Gang. Yang Sheng beside Gu Qing is also the leader of the Qing Gang. Only the leader of the two people in front of him knew the identities of Zhang Yugong.

The sound of horse hooves came, and a group of horses were seen rising from afar. Dozens of members of the Qing Gang blocked the intersection and asked the other party to stop the horse.

"Who is here?" Zhang Yugong asked with a long sword in his hand.

"Know your opinion, get out of here!" the other party shouted as he rode his horse.

Zhang Yugong continued, "This road has not been peaceful recently. If you don't have any important matters, please change the way."

This is the only way to the village. When people saw a group of strange people in front of them, dozens of people riding horses were vigilant and touched the sword behind them. The dozens of men wearing masks were also carrying swords and weapons. They were not ordinary people, but like horse bandits. How could there be horse bandits near Chang'an?

"Don't you want to leave?" Gu Qing also stepped forward and asked.

"I have something important to do, so I will ask a few heroes to tell you how much money we need." Now I don't want to cause more trouble, but I have to rush to get in touch with the Zheng family.

"Then I'm going to ask." Gu Qing said again, "This road only leads to a small village. Where are you doing what you are going?"

"A few heroes, I advise you not to cause trouble." The other party said again, "We are from the Zheng family! Xingyang Zheng family, can you offend them?"

"That's a coincidence." Gu Qing said with laughter, "I have often dealt with people from the Zheng family recently."

As Gu Qing spoke, Yang Sheng had already brought a few people to the rear of the horse team.

The other party also looked at Gu Qing wearing a mask and said, "Since you are an acquaintance, you might as well borrow a story."

"It seems that this Tao cannot be lent to you." Gu Qingyouyou said, "It's just that we have killed a lot of people from your Zheng family. You can come and kill a few of us!"

"What did you say!" The leader in front of him pulled up the reins and immediately noticed an unusual murderous aura. He was surrounded by surrounding him and shouted, "There is something wrong with the limelight, fight out!"

Yang Sheng waved his hand with a mask. Dozens of members of the Qing Gang pulled out their swords. All the members of the Qing Gang led by Zhang Yugong came down from the battlefield, with a murderous aura on their bodies. They were not afraid of the horses rushing over. These horses in the Central Plains were much shorter than those on the grassland.

"Go!" The other party rode his horse and rushed towards the Qing Gang in front of him.

Zhang Yugong lifted the long sword in his hand, and looked at the rushing horse hooves under the mask, took a deep breath, and waved it down! Blood gushed all over his body, and the horse's chest was broken by the long sword. Before the other party was caught, the hilt of the knife moved to the right hand, and another knife rose, and a head fell to the ground under the clear sky.

A sword is a life! Decisive and merciless.

The people in the horse team hurriedly grabbed the reins and did not dare to move around. With just two swords, we can see that this man is not simple, he is definitely a trainer, and the road is very quiet.

"They are just the few people! Go out!" the leader shouted again.
Chapter completed!
