After seeing Li Shan pour a large glass of wine in one breath tonight, he was also unexpected, knowing that he couldn't drink, after reluctantly drinking this glass of wine, he was really drunk, and he was very disapproving.

Although Xiao Du is also trying to catch up, although he didn't drink much tonight, he also has a look of seven or eight taels, after the night wind blows like this, he is a little drunk, only to feel top-heavy, how can he not exert his strength, seeing that Mao San is pulling farther and farther away, I can't help but feel a little depressed, tonight this is planted!

Suddenly, he saw Li Shan chasing after him from behind, and there was a frame that ran faster and faster, which made him smack his tongue, this kid was obviously even more drunk than himself, how could this be like taking stimulants?

Not to mention that Xiao Du wondered in his heart, they had already run seven or eight kilometers away at this time, although Mao San was very good at running, but he was not an iron man after all, and he would be a little tired. So he wanted to end the game of rats and cats, but at this time, he found that this game was not the end he wanted to end, because he found a figure speeding up towards him.

Peeking at it, Mao San's eyes were very good, he recognized the person who caught up and later intercepted one of his three people, this person had been running at the back, but now somehow, this guy suddenly accelerated to catch up, and it seemed that the speed was quite over.

Li Shan, who was chasing quickly, also aroused Mao San's competitive spirit, and he also started to accelerate and run, wanting to get rid of the person behind him in a hurry. As a good long-distance runner, Mao San knew that if he wanted to drag down his opponent, he couldn't use the method of running at a constant speed, and variable speed running was the most energy-consuming way to run, so this guy suddenly raised his speed.

As soon as Li Shan saw that this guy had accelerated, he didn't dare to slack off, and he also raised his speed.

Seeing that Li Shan also sped up, Mao San sneered in his heart, and after a while, he would see who would lie down first, and immediately strode forward.

The two of them ran for ten minutes under a high-speed sprint, Mao San felt a little lacking, and couldn't help slowing down, looking back and peeking, but saw that Li Shan had also slowed down, and the distance between the two was not too big.

This is a master, or not, let's compete to see who is more powerful.

ran out for another four or five kilometers like this, and only Li Shan and Mao San were left on the road, and the others had already been thrown away.

With Mao San's physique, it is not a problem to run a marathon, he originally wanted to use his natural long-distance running ability and professional running style to drag down Li Shan, but he never thought that not only did he not do anything to the opponent, but he himself couldn't bear it first. He only felt that his face was covered with sweat, his clothes were already soaked, and his chest was almost out of breath as if it was stuffed with cotton. In the long-distance running, Mao San has basically never met an opponent, and when he sees the person who is chasing closer and closer, his original self-confidence is shaking. When did the police have such a good long-distance runner, it seems that they still underestimate these policemen, will they plant it today?

Mao San felt that the wet clothes were sticking to his body at this time, like a heavy burden, so he simply took off his clothes and threw them away. He also lost one of his shoes, and he didn't care about picking them up, so he simply threw off the other shoe when he ran up and down with a twist of one high and one low. Running down the road wearing only socks, he felt only that the air in his lungs was getting thinner and thinner, and his legs were as heavy as lead, until at last he couldn't take a single step, and collapsed to the ground like a pile of mud.

looked at Li Shan, who had caught up, and gasped: "Police, comrade police, I don't, don't run away." ”

Li Shan didn't feel any tiredness at this time, and he still had some unfinished feelings, he came to Mao San, raised his leg and gave this guy a look, "Aren't you quite capable, you should run for me!"

Mao San fell to the ground, still panting, he stretched out his hand and stretched out five fingers and said: "Five, within five kilometers, you are not my opponent, within ten kilometers, we are tied, after ten kilometers, you are amazing!" Mao San was still a little unconvinced, looking at Li Shan running such a long way and still looking at ease, but he couldn't help but smack his tongue a little.

"Do you think this is a race, do you know where you lost, there is a saying called something, yes, that is-justice will win!" Although he was mistaken for a policeman by Mao San, Li Shan did not explain, no matter how he said it, he could be regarded as having a cooperative relationship with the police, and he was barely a member of the people's police, and at this moment a sense of justice arose spontaneously in his heart.

In the days that followed, Li Shan began to prepare for infiltrating the Supreme Guild. If you want to join this guild, you must have a person to introduce you, and he has already thought about it, and this person is locked in Ma Huizhong in the fifth group.

Ma Huizhong himself is a member of the Supreme Guild, and it is said that he still has a certain status in it, and it is best to be recommended by him, so the probability of successfully joining the Supreme Guild will be very high.

Li Shan and Ma Huizhong were originally not very good at dealing with each other, but after the spring test, the relationship between the two has been significantly improved, if Li Shan wants to join this guild, if nothing else, Ma Huizhong will definitely help with this.

Looking for Ma Huizhong to help introduce him, the premise is, of course, to find this person, his home address has been mastered by Zhang Jun's investigation, Li Shan has mastered it, but you can't just rush to find him, this will obviously be a little abrupt, but it will arouse people's suspicions, it is best to pretend to meet by chance, so it is more natural.

It would have been nice to have this chance encounter at the summit joint training ground, where people come and go, and it's extremely natural to come and go.

But because Li Shan was busy, there were not too many opportunities to go to that training ground, and the chances of meeting Ma Huizhong a few times occasionally were not too great, so he handed over this trouble to Zhang Jun, believing that it would not be easy to lock down a person's whereabouts with the ability of the police.

As soon as Zhang Jun heard this, he said that I had violated discipline, after all, in the absence of any evidence, it was still in conflict with the relevant laws and regulations to use public power to investigate a person without hesitation. Li Shan gloated and said: "Don't come, anyway, this matter is handed over to you, you can do it yourself." ”

Zhang Jun was a little helpless when he heard this, so he had to say: "I will keep an eye on his whereabouts, and if I find him at the training ground, I will notify you immediately." ”

Somehow, after a few days, Ma Huizhong has not appeared in the training ground, Li Shan suggested that it is better to go directly to his house to find him, but Zhang Jun said: "This matter can not be rushed, everything should be done carefully, the disappearance of the scout is enough to prove the cruelty of the struggle, we can't take it lightly, it's better to be safe, this is also responsible for you." ”

Taking advantage of this opportunity, Li Shan began to transform the drone that the five groups of awards were given to him. According to his vision, this should be a multi-functional drone, not only to add a special pulverized coal modified battery, but also to have the function of firing bullets, crossbow arrows, lasers, these launchers have different shapes, so it is necessary to make relevant conversion devices to adapt to different needs.

The design of these devices is not too complicated, and Li Shan's ability can do it very well. In the design process of these conversion devices, Li Shan all adopted the concept of quick change, so that the conversion between various launching devices can be completed within a few minutes, which can often play a vital role in actual combat, which fully reflects the profound meaning of the phrase "efficiency is life".

The schematic diagram of the conversion device was designed, and then some acquaintances were found in the factory for processing, and the equipment used to process aero engines in the factory had no problem in processing, but Li Shan was a little difficult about what materials should be used for this kind of device.

This conversion device is used on drones, and the material should be on the premise of ensuring performance, of course, the lighter the better, Li Shan immediately thought of composite materials.

At present, a large number of aerospace parts are made of composite materials, which actually refer to materials composed of two or more substances combined in different ways. This material can give full play to the advantages of various materials in the application, and at the same time, it can also effectively make up for the shortcomings in the application of a single material, so as to further enhance the practicability of the material application. The application of composite materials in the current aircraft can reduce the weight of the aircraft structure by about 25%, and the structural design cost by about 22.5%, so the production cost of the aircraft with a high amount of composite materials, as well as the fuel consumption during flight operation will be greatly reduced, and the application of composite materials in modern aircraft is becoming more and more extensive.

But most of these materials are relatively expensive, not something Li Shan can afford, and many of these materials are strategic materials, which ordinary people cannot easily obtain.

Therefore, Li Shan can only be made of the most ordinary materials at present, and it has brought some problems, that is, it will increase the load of the drone, which will affect the performance of the drone.

Optimized design is a good choice, but Li Shan is not in this business, and it is already very good to be able to design these devices, and then let him optimize them, unless he is looking for some experienced experts.

It would be nice if it could directly reduce its weight, as soon as this thought came to mind, Li Shan suddenly thought that he didn't still have that mysterious jade? Any object placed with this mysterious jade in a vacuum environment would lose weight after a certain period of time, and at the same time, the performance of the object would be improved to a certain extent.

Why can't these devices be vacuumed as well?

Thinking of this, Li Shan was in a good mood for a while, he immediately turned out a metal box from a corner, this metal box has fallen some dust on it, it is the size of an ordinary book, it was originally used as food or medicine vacuum preservation, Li Shan now uses it as a vacuum.
