At night, Zhang Lu was asleep when someone suddenly woke him up.

When he opened his eyes, it turned out to be Su Luo, and now it was his turn to keep vigil, Su Luo made a silent gesture to him, the wild in the middle of the night was very quiet, there were not many nocturnal beasts and beasts in this place, except for the occasional roar, basically no sound could be heard.

Zhang Lu didn't speak, just nodded to Su Luo, tidied up the clothes on his body, and walked out of the tent, while Su Luo was lying in his sleeping bag and said goodnight with his mouth.

Inside the fire, Su Luo had just added firewood, and now it was burning brightly, and he didn't need to add it, the beasts were lying around them, and he couldn't look at his phone now, which would distract him and make him unable to observe the surroundings.

Now there are too few people in their team, if they can be divided into three groups, at least the vigil in groups of two and two will not be so lonely, and it is also thanks to Lin Lin, a girl who talks a lot, that she can stay alone for two hours.

He was now sitting alone in a chair, looking lazy, and it was easy to get sleepy when he was bored, and he could still hit the mental vigilance in the first half hour, and after half an hour had passed, his upper eyelids began to fight with his lower eyelids, and his head was constantly lowered.

He suddenly woke up in his heart and muttered: "No, I can't sleep!" ”

With that, he stood up and began to walk around slowly, trying to relieve his sleepiness, but this method did not last long, so he could only try to wipe his face with a wet towel.

As he was wiping, he suddenly thought, can his spiritual power be used to refresh himself?

Although he had never been taught this kind of thing in school, he thought it was doable!

Mental power is originally related to the brain and consciousness, relying on ordinary learning and using the brain to improve, so if you run your mental power in the brain, can you improve concentration and reduce fatigue?

Thinking of this, Zhang Lu began to mobilize his spiritual power, but how to make sure that his spiritual power was constantly running in his brain?

His spiritual power had just been mobilized and poured out of his mind, emitting a faint blue light in front of him, but this was not the result he wanted.

If he treats his mental consciousness as a room, and his mental power as a feather that fills the room, lying quietly in the room without outside interference, when his consciousness mobilizes his mental power, it is like a gust of wind blowing through the room, and all the feathers are blowing towards the door, but the room has not yet been closed.

What he had to do now was to create a door so that the feathers that would have been blown out would only rotate around the room.

But how do you make this door?

Zhang Lu made some difficulties, did he use his consciousness as the door?

He began to try, using his consciousness to forcibly order those mental powers to only work in his mind and not pour out of his mind, but no matter how he tried, he failed, and as soon as his consciousness began to stir the wind in the room, those feathers would unconsciously float out.

It seems that this path is not working, so is there anything that can be used as a door?

Zhang Lu sat on the chair, looked at the surrounding environment and fell into deep thought, what are the characteristics of the door, can it be closed and opened, can be blocked, blocked.....

Suddenly, he saw a cloud of ash spinning and flying upwards on the fire next to him, instead of floating around.

So what if you control your consciousness and mobilize your mental power to spin? It's certainly not as simple as spinning, but here's how it works.

Zhang Lu began to try again, this time he tried to let his mental power spin in his brain, at the beginning, he only felt that his mind was clear, his thinking was smoother, and his concentration was improved.

But soon, the spiritual power he mobilized began to overflow outward, and the faint blue light enveloped him and gradually dispersed, and the feeling of sobriety did not last long.

This will not work! If it's only for such a short time, and it will disperse, even if he runs out of mental power, he won't be able to last too long, there must be other ways!

He continued to try, and suddenly he remembered that he had originally ordered the spiritual power to stay in his head, what if it was in a more gentle way? For example, when the mental power is about to approach the door, let them turn in the direction of rotation and speed up the rotation?

In this case, you need to invest more consciousness, and there is a limit to what you can pay attention to at the same time, and if you focus too much on mental power, you will not be able to think.

But if this can be successful, after a long period of practice, it should be able to turn into an instinct!

With that, he started a new round of attempts, this time focusing all his attention on controlling the mental power, guiding these mental power to run along his brain, and returning to the original point after a circle.

From an outsider's point of view, Zhang Lu seemed to be asleep, without any consciousness, and his eyes were closed and he did not react to anything in the outside world.

After a long time, he suddenly opened his eyes, and this time his eyes began to glow with a trace of blue light, different from the blue emitted by Du Youqi's pupils themselves, but there seemed to be a trace of blue light around his eyes, which he really couldn't see if it was in the daytime.

"It's done!"

He couldn't help but scream, but before he spit out those two words, he controlled the volume and didn't wake his teammates.

But now all his energy is now focused on controlling his mental power, and the surrounding environment and dangers are really difficult to pay attention to.

But the vigil still had to be kept, and after weighing the pros and cons, Zhang Lu walked to the side of the scourge and patted its head.

Scourge woke up when he felt someone approaching, but he noticed that it was his master, so he didn't react, but what he didn't expect was that his master slapped himself as soon as he approached him.

The aggrieved scourge made a whimpering sound, and his head leaned against Zhang Lu's pocket, as if to say that this matter would not be over without an energy block.

Zhang Lu lowered his voice and said: "Okay, don't use your strength again, don't make any noise, pay attention to the surrounding situation, if something is approaching, you have to warn, do you hear?!" ”

Seeing Zhang Lu's serious expression, Scourge stopped playing tricks, and responded in a low voice, indicating that he understood.

"I'll give you energy blocks when the vigil is over!"

After Zhang Lu said this, Scourge immediately came to his senses, saying that he must keep a good vigil, and put on a look of looking around, never missing any direction.

Zhang Lu shook his head, closed his eyes, and restarted the method he had just tried, becoming more and more proficient in the operation of circle after circle.

What he didn't know was that he had inadvertently mastered another method of using spiritual power that would not be taught until the university.
