Spiritual power, as Lu Yu's killer weapon at present, is definitely the top priority, and even after Lu Yu plans to strengthen his cultivation to level 3, he will first suspend the strengthening of his cultivation and use the remaining points to strengthen his spiritual power.

A person's mental power is strong, it can be said that the impact is very large, related to all aspects, not only can be used to kill the enemy, including the strengthening of memory ability, the activity of thinking ability, the sharpness of the five senses, and even the strengthening of willpower.

The reason why ordinary low-level martial artists can't even run away when facing high-level martial artists is because the difference in cultivation is too big, and on the other hand, the suppression of mental power makes you unable to mobilize your body even if you want to run.

It is said that a powerful high-level martial artist can directly control a person's body and completely imprison a person with mental power.

It's okay to even fly with a person with mental power, if you want to kill someone, you can crush a person directly with mental power, which shows the horror after the mental power is strong.

After understanding the role of spiritual power, Lu Yu wanted his spiritual power to become stronger, not only when it was used against the enemy at a critical time, but also when it met a high-level martial artist, he also had a chance to escape and save his life.

It is not easy to become strong in spiritual power, and ordinary martial artists can only sense spiritual power when they hit the realm of grandmasters in the late stage of level 6.

Of course, there has never been a shortage of geniuses in this world, and they can sense spiritual power earlier, and even if they do, they can't cultivate much faster.

However, being able to sense spiritual power earlier is a decisive talent, and it is much easier than ordinary martial artists to break through the realm of grandmasters.

Therefore, the martial artists who can sense the spiritual power in advance are all peerless geniuses, and they are the enrollment objects that various colleges and universities compete for, because that means that if this person does not die young, it is basically certain that he will definitely become a generation of grandmasters in the future.

However, for Lu Yu, who can strengthen his mental power with points, it is like a local tyrant player has met a cheat, even if he is dressed in white, I will directly attack a thousand times, even if you are covered with top-level equipment, it is not enough for me to slash 999 seconds.

However, even if Lu Yu strengthens his spiritual power, it will be much slower than his cultivation, because the elixir for the recovery of spiritual power is very scarce and expensive, and the things that can strengthen his spiritual power are basically peerless and valuable, and Lu Yu can't get them at all.

Therefore, you can only use the Recovery Pill to strengthen your mental power, but the role of the Recovery Pill is to restore the consumption of the body, and the main recovery is qi and blood, and the effect on the recovery of mental power is not strong.

It is not difficult to use points to strengthen mental power, but the difficult thing is that the body cannot adapt after strengthening, or the brain cannot adapt.

To use an analogy, a table tennis ball in the brain with good mental strength, as long as the points are enough, it is no problem for Lu Yu to strengthen him to the size of a football with points, but the consequence is that his brain is crowded. Because the space that the brain can accommodate is a little bit adaptable to the increase, and if it suddenly increases, it will definitely not be able to stand it.

The effect of the recovery pill is to speed up the speed of this adaptation, although the effect is not large, but it is also much faster than natural adaptation. At present, Lu Yu's mental power is still very low, so the Level 1 Recovery Pill is still very effective.

After eating a recovery pill, Lu Yu's spiritual power was strengthened to 79 points, it is not easy to increase mental power, 10 points in the early stage is a bottleneck, between 70 and 79 points, it takes 4 points to increase a little. And it takes 400 points to break through 79 points to 80 points.

Lu Yu gritted his teeth, and directly spent 400 points to break through to 80 points, and then ate a recovery pill to start strengthening, this time the effect of the recovery pill was reduced a lot, and two level 1 recovery pills were strengthened to 89 points in a row, and every time a little mental power was strengthened between 80 and 89 points, 5 points were consumed, so it took a total of 45 points.

But it takes 500 points to break through the bottleneck from 80 to 90 points, Lu Yu did not hesitate, he directly spent 500 points to choose to break through, and then continued to strengthen without stopping, leaving the last level 2 recovery pill in his hand, Lu Yu threw it into his mouth and began to continue to strengthen.

The effect of the Level 2 Recovery Pill is much stronger than that of the Level 1 Recovery Pill, and it has been supported until Lu Yu is strengthened to 99 points, and the enhancement to 99 points consumes a total of 54 points for Lu Yu, and the need to break through to 100 points from 99 points is no longer 600 points, but 1,000 points.

"Isn't the system, according to the law, supposed to be 600 points? Why did it suddenly rise to 1000 points, saying, did you embezzle me? This spiritual power enhancement is really too consuming of points, and the corners of Lu Yu's mouth twitched in distress.

"The system will not embezzle any points from the host, the reason why 1000 points are needed is because 100 points of spiritual power represent the spiritual power of the great grandmaster-level martial artist, that is, the spiritual power of the level 8 martial artist is only 100 points at the beginning, and if the grandmaster wants to break through to the great grandmaster, increasing the spiritual power to 100 points is one of the requirements."

"Grand Master?!" Lu Yu was shocked, and suddenly he recalled that the system seemed to have explained to him just now, the spiritual power of the grandmaster level is 50 points to 99 points, so if it is calculated, then 100 points is indeed the spiritual power of the great grandmaster realm. Level 8 martial artists, there are not many in the world, and they are definitely one of the highest combat power of the human race.

Which level 8 martial artist is not admired by 10,000 people, the megatron side, there are only 31 level 8 great masters in the country, and the average province is less than one, you must know that the great master can have a lifespan of 500 years, 500 years, only 31 people, you can imagine how difficult it is to cultivate to level 8 great grandmaster.

"I only need to spend a thousand points to break through to the Grand Master? Hey, hey, hey, hey. Lu Yu smiled stupidly, completely stunned, that is, as the saying goes, he flew away.

"Remind the host, it's just that the spiritual power has initially reached the level of the Great Grandmaster, that is, the level 2 spiritual power 'Li Mang Realm'. It's not that the cultivation has reached level 8, so even if the host encounters a level 7 grandmaster, it is not an opponent. ”

", don't bother Uncle Shuang, why don't you have so much eyesight, I don't know what to do? Isn't that just fantasizing? But do you dare to say that the spiritual power equivalent to an 8-level Grand Master is not awesome? ”

The system has nothing to say, it is really awesome, if this is known by the martial artists of the outside world, Lu Yu will definitely not be able to escape the fate of being sliced and studied, as long as this method can be popularized by all mankind, then the day when human beings are really not far from defeating the demons of the other world.

"Host, you still have 99 spiritual power, not 100 points."

"Oh yes, what else are you inking? Hurry up and give me strengthening, isn't it 1000 points? Don't you have any money? ”

With Lu Yu's order, he suddenly felt a 'boom' and his brain exploded.
