A little red light suddenly lit up.

Around the light, you can clearly see that the space seems to be affected by the light, from the calm just now to a slight vibration.

After this lasted for a while, the red light suddenly burst like fireworks, and suddenly burst out countless bits of light, making the whole room suddenly bright.

Then the scattered lights burst out at the same time as the previous red light, becoming more and more tiny lights of different colors.

Under the influence of these lights, a larger area of space began to shake slightly, and the ripples of space shock continued to emerge, impacting, offsetting, or becoming more violent.

It's like a pond suddenly encountered rain. At first, only a little raindrop fell and brought a ripple. As the rain grew stronger and more raindrops fell, the water surface of the pond could no longer remain calm.

After the light burst several times, the scattered light has almost filled the whole room, and the space in the room has become extremely unstable, and the space energy has also been driven to become tyrannical.

Seeing that the furniture and other items in the room were about to be affected by the light of the explosion, Chu Nan turned his mind and re manipulated the space energy that entered the tyrannical state to become calm and stable.

It took him three times as long to finally achieve this, which was much harder than the tyranny caused by the explosion of space energy.

However, the space energy in the room is finally restored to stability, and the influence already suffered in the room cannot disappear.

Looking at the tidy room just now, Chu Nan could only shake his head reluctantly.

It seems that he thought too simply before. After all, class a skill is different from those low-level skills. No one is so easy to control.

If he had known this, he shouldn't have stayed in the dormitory to do it.

If they wait until Mondeo comes back and see Chu Nan make this look in the dormitory, I'm afraid even Yoko Tanaka, who has always been the most stable personality, will be angry.

After thinking about it, Chu Nan shrugged.

Anyway, it's already like this. On the contrary, you can let go.

Chu Nan couldn't help laughing when he recalled the A-level skill he had just experimented with, which had just been redeemed from the martial arts database.

"No wonder this skill is called Nebula chain explosion. As soon as the skill is used, it will drive the space energy in the whole space, like igniting explosives, and produce chain explosions. The power can't be underestimated."

Chu Nan lowered his head, opened the personal terminal on his wrist, transferred the relevant data of the skill of nebula chain explosion, and began to read it carefully again.

This A-level skill called Nebula chain explosion was naturally redeemed from the martial arts database of wuzhe branch.

As for why I exchange this skill... The purpose is to earn points.

Before that, the reason why Chu Nan's students' points in wuzhe branch increased rapidly was that he exchanged skills from the martial arts database, then improved them, and then incorporated the improved skills into the database to reward points in this special area.

However, Chu Nan used to focus on low-level skills such as level F, level E or level D, and earned more than ten or dozens of points at a time.

Now, in order to improve his points faster, he can exchange luohanba body gold body and other five S-level skills as soon as possible. Of course, it's not enough to improve by studying these low-level skills, because it's too slow.

Just now, the college has temporarily upgraded his student level to s level, which makes him qualified to exchange higher-level skills, so Chu Nan naturally focuses on these higher-level skills.

After director Wang Sicheng told Chu Nan that his temporary permission time was eight months, Chu Nan didn't waste a day. He was seizing the time to exchange martial arts research from the martial arts database every day.

At first, he was relatively conservative. First, he exchanged several d-level Kung Fu practitioners. When he found the feeling, he gradually improved.

It is not difficult for him to improve level C skills. He can even improve more than a dozen Level C skills in a day, and if the level C skills are improved successfully, he can earn at least 100 points and thousands of points in a day.

But Chu Nan calculated that even if he could successfully improve each skill, it would take him at least three months to earn 100000 points, enough to exchange for Luohan Ba body gold.

This also requires him to maintain such high-intensity skill research every day for these three months, which is obviously unrealistic.

So Chu Nan worked like this for a week. After raising his points from 7917 to 16398, he focused on Level B skill.

Compared with level C skill, level B skill has reached a higher level and its power has been greatly improved. Naturally, the difficulty of learning and mastering it has also been greatly improved.

It is much more difficult to improve level B skill and successfully obtain rewards.

After Chu Nan changed his goal to level B skill, his points didn't increase but decreased in the first few days. The reason is that although he successfully improved several level B skill methods, two of them didn't succeed at all.

The unsuccessful level B skill not only can't get the reward of points, but also the points spent by Chu Nan can't be returned. It's a pure loss.

So after conversion, his points become less.

However, after becoming proficient, Chu Nan became more careful in choosing the study of Kung Fu, and the problem in this regard was much weaker.

Although the research is more difficult, once the level B skill method is successfully improved, it will be evaluated and recognized in the martial arts database, and the score reward will be very high, at least thousands of points for any one.

Even if the risk of failure still exists, Chu Nan can earn points comparable to studying ten C-level skills as long as he completes one B-level skill in an average day.

And if we can successfully study the two subjects, the benefits will be much higher.

So after that, Chu Nan studied level B skill continuously for half a month, successfully improved 27 skills and raised the score from 16398 to 41372 in one breath.

If it continues like this and continues to maintain the rising speed of points, Chu Nan even needs to stick to it for another two months, which is enough to exchange Luohan Ba body golden body skill.

However, Chu Nan was not satisfied at this time. He turned his eyes to class a skill.

This nebula burst is his first class a skill.

If Chu Nan's research is successful, he will improve this A-level skill. According to the skill exchange reward regulations in the martial arts database, he will even have the opportunity to obtain an ultra-high reward of more than 10000 points at one go!

But if it fails

It cost Chu Nan 35000 points to exchange the nebula serial fireworks. If he fails, he will not lose his money - after all, it is also a powerful skill, but it will still suffer heavy losses, which will greatly delay his plan to exchange Luohan Ba body gold.

So Chu Nan now takes this skill very seriously, even more seriously than he has ever studied and mastered any skill in the past.
