Of course, he showed a very remorseful look in front of Lao Gu, just saying that it was just such a simple way, but he could spend such a big price on himself, shouting that he had lost a lot, and he was so angry that Lao Gu blew his beard and glared, saying that you kid has taken a big advantage, this is a set of methods that the old man has summed up after years of hard work, you only paid such a small price to get it, obviously you got it cheaply and sold well.

In fact, Lao Gu also has his own Xiao Jiujiu in his heart, his debugging method is simply a chicken rib, and when modifying the drone, it should be provided to Li Shan, and Li Shan doesn't know much about this, and he didn't ask this old Gu for this method, Lao Gu also pretended not to know, no, now he has made a small extra money.

The two of them have their own hearts, and they both feel that they have taken advantage of each other.

At this point, the transformation of the drone is basically completed. The transformation of the drone is based on a mature technology, and for the control, it requires my talent and acquired efforts.

In terms of control, for Li Shan, who can barely reach the passing standard, his starting point is low, even if he trains hard in the later stage, he can only reach the top of the amateur level, and if he wants to enter the professional level, the difficulty is comparable to ascending to the sky, and he feels discouraged when he thinks about it.

Although the future is bleak, Li Shan has not given up, has been training hard, his principle of doing things is that as long as he does his best, due to the lack of talent to limit his own development, then can only be resigned to fate, as the so-called plan in people, success in the sky.

He no longer practices alone behind closed doors as before, and proper professional training is an effective way to improve the level of operation.

The summit joint training facilities are very complete, but there are too many people who ask for training every day, and the space is limited, so only the reservation mechanism can be implemented. For those with high levels or certain positions like Li Shan, they can get some priority, such as cutting in line or something, but this is only a little more privilege than ordinary people.

Moreover, there is a strict limit on the training time there, and he can only train for two hours a day at most, and he often has just found his senses but has to stop, which makes Li Shan feel very unhappy. Besides, limited talent makes him have to spend more time than others.

It can't go on like this, Li Shan secretly pondered. Wouldn't it be much more free to train at home?

Li Shan has not thought about this aspect, but this kind of training requires a certain amount of equipment, and there is no training equipment sold in the market at all, even for people of Li Shan's class, the cost of its purchase is also beyond his reach.

Therefore, it is a good choice to design and manufacture a set of training equipment suitable for yourself. However, to make a device that costs less and can have a certain effect, it is necessary to design it well.

After studying the training equipment of the Summit Alliance, Li Shan came up with a simple training facility on his own.

The first thing that came to his mind was the height limit line that his family had originally used for cultivation. With the continuous improvement of their own ability, this height limit line is no longer needed. And now that it's going to be used as a training device for drones, he plans to reuse the rope.

He first purchased a set of movable pulleys, and then connected the laser receiver of the summit joint fire to its lower part with iron wire, so that the pulley and the laser receiver formed a movable target. A rope is passed through the middle, which is fixed to the two walls at both ends, and the pulley on the target can run along the rope.

In order to realize the automatic operation of the target, the two ends of the rope are deliberately set to one high and one low, so that a certain height difference is formed, and the target uses its gravity principle to slide down the rope from high to low, and when it reaches the end of the rope, it is pulled back to the high end with the index rope attached to the target, and so on repeatedly.

When the target was gliding along the rope, Li Shan controlled the infrared emitter on the drone to track and shoot at it.

In this way, Li Shan will be able to train independently at home.

He first let the drone hover in a fixed place, shoot at the moving target, and after the shooting accuracy has a certain foundation, and then in turn, the target is fixed, so that the drone can shoot in operation, and finally gradually transition to the extent that the target and the drone operate at the same time.

Although there is a high degree of freedom to train at home, this training method is too inefficient, and after each run, the standard rake has to be put back in place, so that the rhythm and continuity of the training have to be interrupted.

In response to the above problems, Li Shan has improved this system.

He also purchased a small brushless motor from the Internet, through the motor to control the operation of the target, but also can adjust the speed of operation according to the need, so that the training efficiency has been greatly improved, but because of its low level of automation, it still can not meet the actual needs.

Therefore, Li Shan once again transformed this training system, the most important of which is to install a set of automatic controllers, which cooperate with brushless motors, so that the target can run automatically back and forth on the rope as needed, so that this training system is completely automated, thus greatly improving the training efficiency.

After repeated intensive training, Li Shan's handling ability and shooting skills have been greatly improved.

He is currently training with only the kind of infrared emitter, but its shooting principle is basically the same as that of a laser attacker, so as long as the infrared shooting technology is practiced, if the drone is replaced with a laser attacker, its effect will not be affected at all.

Due to the limited space at home, flight training can only be carried out outdoors, but fortunately, the device designed by Li Shan is simple and easy to install, so it has not been greatly affected during outdoor training.

With the improvement of the training level, Li Shan unconsciously compared with the tenth-level master Zhang Jun, for a real professional pilot, Li Shan had only come into contact with him.

At that time, Zhang Jun's excellent control skills during the competition made Li Shan breathtaking.

He unconsciously compared with this target person, and felt that with his current level, I am afraid there is still a certain gap, but the gap should not be too big.

Since the last time he saw the level of these people at the summit joint training ground, Li Shan has not dared to play, he knows that at the level at that time, like a toddler, anyone in this field can abuse himself.

So he's been training hard and hoping to show his skills there one day, and now through this stage of hard work, he thinks he should be qualified to make his debut at his current level.

On this day, Li Shan once again came to the training ground of the Summit United. The fee for the training ground is calculated on a daily basis, and even if he did not play last time, the fee paid for the last time is automatically forfeited, and if he wants to play again, the fee will be paid separately.

When Li Shan came to the battle training ground, he found that the hall was full of people, and there were no vacant seats in the few seats, and some of the people without seats were standing, and some were sitting on the ground, which made Li Shan a little surprised.

Li Shan wanted to find someone to fight, and after looking around, he didn't see the guy who saw the "Supreme" guild, which was okay, so he didn't have any entanglements, but he didn't see any acquaintances.

With the experience of the last time, Li Shan came to the bar to register, and then went to the equipment window to pick up the consumables.

He is no longer clumsy about sticking sensor films, and he will be processing it in a short time. After shaking it a few times and feeling that it would not be easy to fall, he packed up his things and walked to the large display in the hall.

Since that display was scrolling, it took a while to see the name of "Breathing Fish" appear on the screen, which was his own ID, which is currently ranked 68th, and there are three other columns of data after the name, all of which are currently 0.

After looking at it for a while, Li Shan understood the meaning of these three columns of data, the first column was the number of opponents killed that day, the second column was the number of kills, and the third column was the total number of kills. Since Li Shan has not yet participated in a match, all three of his stats are 0.

There are many other people on this list who are tied with him at 68th, and the first two columns of these lists are the same as him, and only the last column of these people has more or less numbers.

Maybe some kind of test is going on in the training ground, so the data on the big screen changes from time to time.

After understanding this, Li Shan stopped paying attention to the big screen, and he passed through the large crowd in the hall, preparing to go to the training ground to participate in the battle. It's just that he can't figure out why there are so many people today, and he remembers that there weren't many people when he came here last time.

With this doubt, Li Shan came to the door leading to the training ground, and when he was about to push the door out, a person next to him stopped him, saying that he wanted to see the documents.

Li Shan saw that he had a sign on his body, and knew that it was the staff here, remembering that the last time he came here, he didn't see this person, and he felt a little strange in his heart, but he still handed his ID and race card to the person.

Maybe he felt that Li Shan was a little strange, the man glanced at Li Shan more, he took the documents and looked at them, looked up at Li Shan again in some surprise, and then handed back those documents to Li Shan, but did not say anything.

Li Shan saw that he didn't have any superfluous expressions, so he pushed open the door and prepared to go out, when someone in the room shouted: "Old Qi, he won't be your acquaintance, why did you let him in just after someone came, it's a bit too much!" Although this man seemed to be joking, his words were full of criticism.
