Because Xu Le has the golden finger of the simulator, he has never made an oath to his ability in reality.

Even Xu Le in the simulation has his own life and ideas. It's not just about satisfying yourself with a simulator in real life. And deliberately made a vow to set limits on his life.

Therefore, even in the simulation, Xu Le's strength was too weak in addition to the previous few times, and he made a vow in order to improve his strength as soon as possible. Later, only when the key ability of "door" was improved, the oath was made.

Moreover, making a vow to improve the ability of the "door" is not for Xu Le in reality. It's so that you can surpass the hunter world in the simulation and not be limited by your thoughts.

Xu Le in that simulation also succeeded. Of all the simulations Xu Le has experienced, it was the only one that didn't end in death.

If the simulation process is not only virtual, but Xu Le in a parallel world, then maybe Xu Le in that simulation is still alive.

Although the mental ability rewarded by the simulator at the end is the ability to read the vow eliminated, the memory attached to the simulator's reward ability is the memory of Xu Le's vow in the simulation.

Although Xu Le has no experience in making a vow in reality. But there has always been research on the aspect of the oath.

When I asked Nitro for advice on advanced techniques in the Demon Slayer World, I also deliberately asked Nitro about the oath.

This time, the simulation reward is a memory that combines domineering and thought, and contrasts.

Through the comparison of different ability systems, Xu Le can be regarded as thoroughly studying the essence of thought.

After thoroughly studying the essence of the vow, combined with the performance of the telekinesis team sent by V5 in this simulation, Xu Le realized that his previous views on the oath had always been wrong.

Xu Le had always thought that through the power of the oath, the person with the ability to read could accumulate strength all the time, and finally release it to be a one-time one-punch superman.

For example, let a person with mental ability make a decision to fight 10,000 punches with all his strength every day, and the longer the fight, the more powerful it becomes, but he can only attack once in his life, this kind of vow.

Although the telepathic ability cultivated in this way can only make one attack, this attack is enough to destroy a town.

Xu Le has always thought that this kind of one-time telepathic ability can be cultivated before, and the foundation of V5 is like this.

Once, when cultivating the Ghost Remembrance Army, I also thought about cultivating a group of such one-time consumable minding abilities.

But after figuring out the essence of the oath, I completely abandoned this idea.

Because, this kind of thinking can be said to be completely wrong.

Even if such an oath was made, and the person who made the oath was asked to fight ten thousand punches a day, and it would be like this for decades, hundreds of years, it would be impossible for him to make a decisive attack.

In fact, there is an explanation of the oath in the original anime.

Kurapika's master was teaching, and Kurapika said when he read it that no matter what, even if he made a vow, Kurapika would never be able to make a chain that could cut everything.

Kurapika's final vow was to devote most of his mental strength to defeating the brigade. The restriction is to gamble with one's life, and the middle finger chain cannot be used on anyone other than the brigade.

If you use it on someone other than the brigade, you will be pierced through the heart by the other end of the chain, and you will die.

It can be seen here that there is a limit to the vow, and what cannot be done is what cannot be done.

There is another example, the Phantom Brigade 7, Franklin's telekinesis "two-handed machine gun". Franklin also made a vow about telekinesis.

The "two-handed machine gun" is a two-handed machine gun that transforms two hands into a muzzle and fires chunk-shaped bullets from ten fingers to attack the enemy.

Franklin's oath was to cut off the first two fingers of the ten fingers in order to make the fired telemias more powerful.

Because this is a rare introduction to the content of the oath in the anime, Xu Le remembers it very clearly, and now he deliberately recalls this content and is more sure of his thoughts.

Xu Le remembers that in the anime, this is what this section said.

Of course, you don't have to deliberately modify your fingers to shoot the bullet, but he thinks that "it seems to be more powerful to do so." That's why I cut off my fingers.

In fact, the destructive power of the bullet has been greatly increased as a result, and more effective bullets can be fired indefinitely.

From here, the nature of the oath is clearly illustrated. He thought it would be more powerful. In fact, the destructive power of the bullet has also increased dramatically. ”

This illustrates the effect of the oath, which requires the firm belief of the owner of the ability, so that the ability is improved.

Therefore, the effect of the oath is actually to strengthen the psychological effect of a person. Let the person who made the vow have enough faith to make it, so the power of the ability has been enhanced.

In other words, even if you don't make a vow, as long as the belief of the person who recites the ability is strong enough, his ability to read can be improved.

On the other hand, if a person's faith is not strong enough, even if he makes a vow, his mental ability will not be improved.

In fact, the oath itself has no effect, but when the oath is made, those who recite the ability will make an agreement, and those who recite the ability are afraid of the price to be paid for breaking the oath, so they strengthen their faith.

It's as if someone is staring at him all the time, telling him that if you can't do it, you'll die, and if you can't do it, you'll die.

In the face of life and death, people will burst out with all their potential, and their abilities will be improved as a result. It's just that this person who stares at him all the time has become his own subconscious.

Because the price paid is real, the person who made the vow will naturally think that I will get the corresponding result if I pay the price.

So, as long as the belief is firm, the ability to read will be infinitely improved?

Obviously not, no matter how firm a person's belief is, his upper limit is also the limit of what his spirit can adhere to.

This goes back to the previous question, why does a person make a vow to fight 10,000 punches a day and only one punch in his life. Fight for decades, hundreds of years, and the power will not be too great.

Because, what the oath can do must first be believed in yourself. That is, to match your own mindset.

This condition excludes change, manifestation, release, manipulation, and characterization. Only the reinforcement system remained.

Secondly, there is an upper limit to the oath, and the upper limit of the oath is the firmness of a person's will.

But that's not all, no matter how determined he is.

The upper limit of the attack power that can be accumulated in the body is also limited by the body, which means that the strength of the body is as strong as the punch can be hit.

If there is a situation where the will exceeds the body, there is a high probability that the person will not continue to accumulate power, but the moment the physical limit is surpassed, the person will explode and die.

This explains why Xu Le will give up the cultivation of the Nian Ghost Army in this simulation.

Because, it's not worth it at all. People with low potential, who work hard for a lifetime through vows, reach the upper limit, and it is just an itch for the strong.

It is a complete waste of talent to let people with high potential make such a vow.

Because, even if a person with high potential makes this kind of oath, the final result is most likely to kill some ordinary people.

As long as you have the ability of a space system, you can solve the problem and hide in another space.

No matter how powerful it is, it can't hurt the important people hiding in another dimension.
