On the top of the mountain, a group of roller skating groups began to form houses, this workshop is not like ordinary workshops, in Gu Qing's idea is to enclose the whole mountain and build a bunker-style factory, the whole mountain runs through from the inside, and this factory has to build a lot of things.

Li Chunfeng hurriedly came to find Gu Qing, "I can be regarded as finding you, let the old man wait for you for a long time, but he waited in vain." ”

"What's the matter with Daoist Li" Gu Qing wondered, Li Chunfeng was already out of breath on the mountain.

"Geometric algorithms!" Li Chunfeng said, "Don't tell Poor Dao that you have forgotten!" You promised that day. ”

"I forgot." Gu Qing said.

"You!" Li Chunfeng wanted to speak and stopped, "You really ......"

"Hehehe, Daoist Li don't be in a hurry." Gu Qing persuaded him, "Now that I think about it again, this geometric algorithm is very complicated, and I can't explain it for a while, so let's start from the most basic." ”

"The most basic," Li Chunfeng sneered, "Poor Dao still needs to learn Gu Qing from the very basics, you don't look down on Poor Dao's math skills." ”

"Nothing, nothing." Gu Qing said with a smile, "Then let's start from the basics." ”

"......" Li Chunfeng thought to himself, how is it still the most basic.

Gu Qing found a piece of paper that had not been written from the pile of drawings next to the construction site, and drew an isosceles triangle with a charcoal pen, "Daochang Li, you should know what this is." ”

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

Gu Qing said again, "Actually, this triangle is also divided into several kinds, but it is the same, and the three corners of its three together are exactly a semicircle. ”

"There is such a thing," Li Chunfeng wondered.

"Daochang Li might as well try it." Gu Qing said with a smile, handing over this problem to Li Chunfeng and continuing to stare at the construction of the factory.

Li Chunfeng looked at the triangle in front of him, the three corners together are exactly a semicircle, is there such a thing, so he drew a very neat triangle by himself, carefully tore off the three corners, spliced them together, and his eyes suddenly straightened! It's really a semicircle.

After countless experiments, Li Chunfeng was short of breath, as long as he drew a neat triangle by himself, and then spliced the three corners together, all of them were a semicircle, as if he had discovered a new continent, and he had never noticed such a wonderful thing.

Looking up and seeing that Gu Qing was no longer here, he came to the office of the study with an anxious mood in his heart, Li Chunfeng kept drawing triangles with Gu Qing's charcoal, his eyes changed very often, why didn't he discover this mystery for so many years, deduced the rules of the triangle in his mind, and a wonderful feeling lingered in his heart.

Explain the things of the factory to Zhang Jie, and give a few instructions, focusing on safety, things that can use tools, don't let the workers do it, Gu Qing and Yang Sheng walked to the entrance of the village together, the forest here is full of green, and it is the season of recovery of all things, and they came to an ambush point of the Qing Gang and watched from afar, "The Zheng family still sent eyeliner over, is this news reliable?"

"It's their retainers who said it." Yang Sheng said.

Gu Qing stepped forward with a mask, and the members of the Green Gang in front of him all wore masks on their faces, and said to them, "The brothers are fortunate to have suffered these days. ”

Zhang Yugong looked at the style of the mask and heard a familiar voice, hurriedly saluted and said, "See the lord!" ”

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

Is the title of lord also used in the Tang Dynasty Gu Qing took out a small piece of silver cake and handed it to Zhang Yugong, "Give the brothers a drink, don't save it." ”

"Thank you, my lord!" Zhang Yugong said, the person in front of him is Gu Qing, the decision-maker of the entire Green Gang, and the behind-the-scenes financier and founder of the Green Gang, Yang Sheng next to Gu Qing is the leader of the Green Gang, and the identities of the two people in front of him are only known to Zhang Yugong, the team leader.

The sound of horses' hooves came, and a group of horses were seen rising from a distance, and dozens of members of the Green Gang stopped at the intersection to stop each other.

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

"Get acquainted, get out of the way!" The other man shouted on his horse.

Zhang Yugong continued, "This road has not been smooth recently, so if you don't have anything important, please change the route." ”

There is only one road leading to the village, and the people who come see a strange group of people in front of them, dozens of people riding horses behind them are vigilant and touch the knives behind their backs, these dozens of people with masks are also carrying knife soldiers, not ordinary people, but like horse bandits, how can there be horse bandits near Chang'an

"Don't you want to go," Gu Qing also stepped forward and asked.

"I'll wait for something important, and I'll ask a few heroes to open a way, and we'll give you as much money as you need." Now I don't want to make more trouble, and I have to rush to connect with the people of the Zheng family.

"Then I'm going to ask." Gu Qing said again, "This road just leads to a small village, where are you going to do something?"

"A few heroes, I advise you not to provoke right and wrong." The other party said again, "We are from the Zheng family!" Xingyang Zheng family, have you offended?"

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

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

The other party also looked at Gu Qing who was wearing a mask and said, "Since they are acquaintances, you might as well borrow a way." ”

"It seems that this word cannot be lent to you." Gu Qing said leisurely, "It's just that we have killed a lot of people from your Zheng family, we will kill a few of you!" ”

"What did you say!" The leader in front of him pulled up the reins and immediately noticed an unusual murderous aura, and he was surrounded by a surround and shouted, "The limelight is wrong, there is a problem with the idea, kill it!" ”

Yang Sheng didn't speak and waved his hand with a mask, dozens of members of the Green Gang all pulled out their knives, and all the members of the Green Gang led by Zhang Yugong came down from the battlefield, with a murderous aura on their bodies, and they were not afraid of the horses rushing over, these horses in the Central Plains were much shorter than the war horses on the grassland.

"Drive!" The other party rode up and rushed towards the green gang in front of him.

Zhang Yugong lifted the long knife in his hand, his eyes under the mask looked intently at the galloping horse's hooves, took a deep breath, and swung the knife down! Blood gushed out, the horse's chest was broken open by the long knife, and before the other party fell off the horse, the left hand of the knife was changed to the right hand, and another knife rose, and a human head fell to the ground under the clear sky.

The knife is human life! Decisive and merciless.

The people in the horse team hurriedly pulled the reins, not daring to move, just two knives, you can see that this person is not simple, he is definitely a practitioner, and the road is very quiet.

"That's all they have! Kill it! The leader shouted again.

"Do it!" Gu Qing said to this person from the Green Gang.
