What surprised Li Shan even more was that according to Yang Rong's own experience, he could already feel the heat in the palms of his palms when he was practicing, not only that, but he also felt a stream of heat from the palm of the tiger's mouth, extending along the inside of the arm to the torso of the body, and this was just the effect of his practice for more than 20 days.

How is this possible, is this the so-called miraculous material for practicing martial arts? When Li Shan practiced the exercises himself, he felt no other sensations except that the palms of his hands were a little hot and sour at first. And as time passed, the feeling of heat in the palm of the hand disappeared.

When he was young, Li Shan also practiced for a few days, and he also imagined that he was the rare practice wizard in martial arts movies or novels.

However, the reality is so cruel, among the students who practice together, the coach often arranges for several of them to go to the front of the team to demonstrate to everyone, from the coach's eyes, Li Shan saw the appreciation, and when the coach faced himself, if it wasn't for the sake of tuition, it is estimated that he would not ignore himself.

Li Shan also had some doubts, thinking that Yang Rong was bragging13, and his own feelings when practicing may sometimes be just an illusion, the so-called sense of qi, he can't see or touch it, he can only talk to himself, there is no genius in the world, but this person happens to be him.

Thinking of himself from Yang Rong again, it turned out that he was indeed not a genius in cultivation, which made Li Shan feel frustrated, but he did not lose confidence, he also had his own killer weapon, and this killer weapon was the laser.

Li Shan knew that this weapon would not be used easily, and it would bring him a lot of unnecessary trouble.

But it's a pity not to put it away, looking at the laser in my hand, I can't make a choice for a while.

It is better to actually operate it first, familiarize yourself with the use characteristics and characteristics of this laser, and if you want to use it one day in the future, you will not be caught off guard for a while.

There is a small park two kilometers away from Li Shan's house, where there are usually not too many people, basically some uncles and aunts are there walking, playing tai chi, dancing square dances or something, and there is no one after 10 o'clock in the evening, which is an ideal place to test lasers.

Li Shan deliberately waited until after eleven o'clock in the evening to arrive at this place, and as expected, it was already empty.

The park is next to a road to the west, this road is not the main road, occasionally some cars pass by, but the drivers are driving intently, no one will notice the grove next to it, to the north is a farmer's market, which has long been closed by this time, and to the east is a residential area, separated by a brick wall.

The park is not very large, the trees are not very dense, and the street lights on the road to the west make the light in the woods not too bad, and it is far from the densely populated area, but it is an ideal place to debug the laser.

But Li Shan was still a little uneasy, so he went around the park to make sure that there was really no one here, and then he was ready to start commissioning.

He placed a target on a small tree facing east, ready to be used for debugging later.

This so-called target is actually a few concentric circles drawn on a piece of white paper, and a small red dot is dotted at the center of the circle, which is similar to the kind of target usually used for professional shooting, but this is drawn by Li Shan himself.

Then glue the target paper onto a piece of cardboard, so that a target is completed.

The reason why I chose to face the east is because there is a brick wall behind it, and the current power of this laser is not enough to penetrate it, so as to avoid some accidents.

After everything was ready, Li Shan took out the laser from his backpack, and the laser faintly shone with a pale green light in the night light.

After admiring it for a while, Li Shan began to prepare for debugging.

He was about ten meters away from the target, and aimed at the target with the laser in his hand, and estimated that it was almost aimed at the target. He took a deep breath, trying not to shake the laser, and then pressed the switch on the laser very carefully, only to hear a "chirp" in his ears, and then the laser shot by the laser pierced a small hole in the target.

Li Shan took a closer look, the position of the small hole was in the second circle of the target, and the current shooting distance was only about ten meters, so close to the distance deviation is so big, if it is farther away, it may be biased to grandma's house.

But that's okay, it's the practice stage anyway, and it's normal to have such a big deviation, which requires repeated practice to improve.

When he went out at night, Li Shan explained to his parents that the unit had to work overtime, so he was not worried about going back late.

In this way, in the process of Li Shan's repeated practice, another two hours passed unconsciously.

At the beginning, Li Shan had no experience, and it was completely a kind of indifferent wave, but later found that this method was not accurate at all.

The main reason for this is that there is no reference material on the laser that can be used for correction, that is, a crosshair similar to that found on ordinary guns.

For this reason, he temporarily glued a small pebble with glue at the front end of the laser to act as a sight, not to mention, with this crosshair, Li Shan's shooting accuracy and accuracy have really improved a lot.

At this time, the small hole shot by the laser is getting closer and closer to the bull's-eye, but it has never been able to hit the bull's-eye.

It seems that after going back, he will have to install a better sight, but fortunately, Li Shan has basically figured out the shooting rules, and he feels that today is a worthwhile trip.

Just as Li Shan was about to finish today's practice, he suddenly heard a faint sound of talking in his ears, which was particularly clear in the silent night.

Somebody's coming? It's very likely, it sounds like it's coming from the west.

So Li Shan didn't dare to act again, it was late at night, if he rashly came out of the woods alone, in such an environment, it was difficult to guarantee that people would not have the idea of either treachery or theft.

In order not to cause misunderstanding among others, Li Shan squatted quietly in the shadows, wanting to wait for the gang to pass before leaving.

"I said brothers, this is remote and uninhabited, I think it's here!" a male voice sounded.

Hearing this, Li Shan couldn't help but secretly complain, could it be that these people came here in the middle of the night, just like himself, to engage in some academic research?

"Okay, let's come in order, it's still the same as last time, buddy come first. A man's gruff voice said unhurriedly, but there was nothing to hear from the words what they were going to do.

"That's not good, last time was last time, this time I put out the most force, if I hadn't overturned this girl, how could it not have fallen into our hands so easily, so this time I should go first. The man who spoke first said, his voice clearly frivolous.

"Paralyzed, I don't know who the boss is, it's all against you. The rough voice said as if it was a little angry.

"As long as you still want to be the boss, just ask our brother who has served you. The flirtatious voice said with some disdain.

Then the two men argued, and both seemed to be a little excited, and the other began to dissuade them.

There were three of them, and Li Shan finally understood from their conversation. He couldn't help but gasp, these guys outside seemed to be preparing to attack a girl, and there was some dispute over who would go up first and who would go later!
