Although the system requires points to be spent to check whether there is a level 10 martial artist, since it is necessary to have points, it is very likely that there really is a level 10 martial artist, and it is not impossible that there is even a level 10 or above.

After all, a level 9 martial artist can live for more than two thousand years, and for such a long time, if he breaks through level 10, it is not impossible, but these are too far away from Lu Yu, so don't worry about it for the time being, it is better to strengthen yourself first.

Lu Yu calculated, strengthening cultivation requires points, strengthening mental power requires points, strengthening skills also needs points, evolution skills also need points, and every time you break through the bottleneck, you also need a point, 7500 points looks like a lot, in fact, it can't be strengthened much, of course, it is much faster than others' cultivation.

At present, it seems that the skills do not need to be strengthened first, and the few skills mastered so far are enough.

Keep the points to strengthen your cultivation and mental power, and use them to cope with the college entrance examination.

Although there should be no problem with the current college entrance examination, if you want to get a good score in the exam and make your parents happy, you still have to work hard.

After setting the goal of strengthening, Lu Yu picked up a strengthening pill and began to sit on the bed to strengthen his cultivation, he is currently a level 2 martial artist, and it takes 2 points to strengthen a little. The so-called level 1 strong skin and flesh, level 2 strong muscles and bones, and level 3 strong viscera.

The muscles of Lu Yu, who has cultivated at the second level, have been strengthened, and because of the cultivation of the 'Black Iron Body', the muscles have been strengthened even more thoroughly than those of ordinary martial artists.

Moreover, it is strengthened with points, it is a 360-degree strengthening without dead ends, and every part of the body is strengthened, including some hidden parts, which ordinary martial artists can't do.

After cultivating to level 2, he began to strengthen the bones of his body, and there were 206 bones in the human body, and after all of them were strengthened, the bone density was greatly enhanced, although it was not as hard as steel, but it was much stronger than a level 1 martial artist or ordinary person.

Therefore, after completing the second level of strengthening, the person's weight will also increase to a certain extent.

But strengthening bones is a very difficult and slow process, because bones are hard and difficult to strengthen.

It's even slower and more difficult than the strengthening of the internal organs at level 3. The data shows how difficult it is to strengthen bones.

The physical strength of a level 1 martial artist is from 10 to 99 points, while the physical strength of a level 2 martial artist is from 100 to 999 points, which has increased tenfold, you know, the physical strength of a level 3 martial artist is only between 1000 points and 1999 points, which is about the same as that of level 2. You can imagine how difficult bone strengthening is.

Of course, although it is difficult to strengthen, but after the strengthening is complete, the strength progress is also great, after the bone is strengthened, not only the bones become strong, but the bone marrow of all the foundations of the body also becomes strong and abnormal, reaching the realm of real bone marrow like mercury and qi and blood like pulp.

As for level 3, after strengthening the five internal organs, the human body will undergo essential changes from the inside out, strengthening the five internal organs and six internal organs, not only enhancing the person's defense and resistance to attacks.

More importantly, after the body has been completely strengthened, it becomes pure and solid, and only in this way can the body absorb the energy that exists in the space and use it.

Therefore, even if a martial artist below level 3 has mastered the method of absorbing energy, there is no way to absorb it, because the body can't bear it, and if one is not careful, it is easy to explode himself on the spot.

Therefore, the first 3 levels are a process of laying a solid foundation, the more solid this foundation is laid, the purer the strengthened body is, the faster the energy absorption will be, and the stronger the strengthened, the more energy it can bear.

Generally, martial artists increase their qi and blood through exercise, or take pills, relying on their own washing, slowly strengthening themselves, if the qi and blood are insufficient, then they need to be supplemented by food or pills, if there is no way to replenish, they can only wait slowly for recovery, before they can continue to cultivate.

And Lu Yu directly strengthened through points, although it will also consume qi, blood and energy, but it will save a lot more than others, so he uses a strengthening pill, which can strengthen the effect of others several times.

After Lu Yu put a strengthening pill into his abdomen, he felt that the strengthening pill slowly dissolved in his body, and the power of hot qi and blood traveled all over his body, and he hurriedly began to strengthen himself with points.

Since Lu Yu is already a level 2 martial artist, the role of the first-level strengthening pill is not great, even if it is strengthened with points, it is only strengthened by about 20 points.

However, Lu Yu did not stop, but continued to strengthen himself, and he now had 10 first-level strengthening pills and 5 second-level strengthening pills in his hands. After using up all 10 first-level strengthening pills in one go, Lu Yu stopped strengthening.

'Whew' let out a sigh of relief, Lu Yu looked at the system layout again, and the data had changed very much.

Stamina: 340/342+

Spiritual Power: 0/0+

Spirit: 75/75+

Credits: 7100

Carry-on space: 1 cubic meter

Skills: Black Iron Body (Dacheng) Extreme Speed Running (Dacheng) Mental Power Manipulation (Xiaocheng) Mental Piercing (Xiaocheng)

The strength value has been strengthened by 200 points, and the points have also consumed 400, although it is still the early stage of level 2, but it is not far from the middle level of level 2 with 400 points, and there are still 5 level 2 strengthening pills in his hand, but Lu Yu did not continue to strengthen.

This time he strengthened 200 points, which is already a little too anxious, and if he continues to strengthen, he is afraid that he will not be able to control his body, which means that his mental power is extremely strong, otherwise there will be a situation where his body is out of control, such as opening the door and removing the door, shaking hands with people and crushing each other's bones, which is possible.

I moved my body to the ground and got used to it a little, and I felt that my strength had changed drastically. Only then did he understand that when he shot Li Hu with a dart, there was definitely some luck in it.

The only drawback of the late level 2 martial artists is in the head, at that time the bones of their whole body have been strengthened, and Lu Yu's darts may not be able to penetrate the bones that have been strengthened.

But the head is the last step of strengthening, so it is more fragile than the rest of the body, and it is because of this that Li Hu was exploited by Lu Yu and shot through the position of the temple.

Feeling the sudden increase in strength, Lu Yu was particularly glad that he had learned the life-saving skill of 'Black Iron Body', if he didn't have this skill, he might have been killed directly by Li Hu's punch.

No, it's not possible, it's going to be killed. It seems that being timid and afraid of death is not a disadvantage. Well, it takes 1,000 points to strengthen the Black Iron Body to perfection, so you can consider this.

After thinking about it for a while, Lu Yu still decided not to strengthen the 'Black Iron Body' first, the current Dacheng's Black Iron Body, plus after all the bones are strengthened in two days, the two should be able to increase a lot of defensive capabilities, and there are no strong enemies at present, it should be enough.

After adapting to his body, Lu Yu returned to the bed and continued to strengthen himself, this time it was no longer his physical cultivation, but he planned to strengthen his spiritual power.

On that day, Lu Xiaoxiao pit a total of 20 first-level strengthening pills, 10 second-level strengthening pills, and the pharmacy gave away 5 first-level recovery pills and 2 second-level recovery pills. Lu Yu also divided 3 first-level recovery pills and 1 second-level recovery pill, which were just used to strengthen spiritual power.
