Lin Chu, who didn't know that he had become a "celebrity", was struggling to support himself in the competition room.

This time, the opponent is a senior of the martial arts department, who has cultivated to the seventh level of qi refining, and is also good at fist and foot exercises, and if he is not careful, he will be put down, and he is tired of coping with it.

Now he can be said to be easy to fight against the sixth layer of qi refining, basically he doesn't need to use spirit stone pills and the like to restore aura, but when he encounters the seventh layer of qi refining, it is a bit reluctant, counting the supplementary spirit stones he consumes, the harvest is actually not as good as the sixth layer of qi refining.

But there is no way, now those challengers of the sixth layer of qi refining have already fought against each other, and some of them have entered this competition room again because of their anger, and now only the seventh layer of qi refining is left who can accept the challenge.

There weren't even many challengers to the seventh level of Qi refining, and there were only twenty or so left.

came to vent and beat for a long time, only to find that the beaten person seemed to be nothing, and few people would be interested in doing it again, and there was no benefit to fighting against him, a freak, and those students gradually stopped coming, and this "Night of Falling Rainbow Valley" that made Lin Chu practice quickly was about to retire.

Bumped.

Seeing that the opponent was swinging his tail again, Lin Chuyi, who estimated that he was choking enough to resist this time, gritted his teeth, ran the mountain-shaking trick, and stepped forward, bullying into the opponent's arms, and had a close contact.

"Bang"

In the dull sound of collision, Lin Chu flew upside down two meters away, and flipped two times on the ground before jumping up, and this knock also allowed him to successfully avoid the powerful leg swinging attack on the opposite side.

"Hehe, that's good, if it weren't for the fact that the degree of spiritual power condensation was really much worse, I would have to lie down this time. Compared to the embarrassed Lin Chu, the senior on the opposite side just shook his body for a moment, and then clenched his fists, ready to continue attacking.

In the next second, the figure of the senior disappeared from the room.

When the challenge time reached an hour, the challenger was defaulted to failure and was then forcibly teleported out by the circle in the arena room.

"Whew"

Lin Chu let out a long breath, and finally got through it, this is the last challenger today, and the closing time of the arena is coming soon.

......

"Brother Chu, I really admire you so much, you quietly rushed into the top 100 of the Green Leaf List. Anyway, how did you get the credits?" Gao Hu said excitedly as he followed behind Lin Chu with a smile on his face, "For the sake of me always saddle up for you, give me some advice, I don't have high requirements, just get dozens of credits as long as you meet the requirements of the academy." ”

This guy had just entered the fourth layer of qi refining last month, and he was considered a good qualification for a weak spirit root, but now he was also facing the problem that Lin Chu faced at the beginning, and he couldn't do the task of earning credits. No, seeing that Lin Chu was actually in the top 100 on the Green Leaf List, he kept waiting outside the door of the small building of the History Department, wanting to seek Lin Chu's guidance.

Feeling a faint pain coming from the depths of the bones in his body, as if it was trembling after being broken and then growing, Lin Chu knew that he was about to complete the bone quenching stage of the sacrificial technique.

At this time, how could he still have the heart to pay attention to Gao Hu, not to mention, why did that green leaf list go crazy and let himself enter the top Bai Lin Chu didn't understand how to instruct.

"Wait until tomorrow to talk about anything, don't bother me now, I have something urgent. ”

Without looking back, he dropped a word, Lin Chu took three steps and made two steps, and he had already rushed to the third floor and hurriedly entered his room.

After smashing fifty spirit stones at once, Lin Chu began the final sprint of the bone refining stage of sacrificing his body.

The spiritual power rushed, penetrated into the whole body, and then was quickly consumed by the sacrificial technique, similar to the comfortable slight itching of the spring breeze that started from the toe bones and gradually spread upward.

If Lin Chu could look inward, he would find that extremely fine lines appeared on the surface of the bones where the itching had spread, and then these lines kept twisting and entangled, and finally disappeared.

The whole process is like breaking all the bones and then putting them together in a denser and more mysterious way.

From the toe bone all the way to the skull, every bone mutates.

Half an hour later, Lin Chu let out a comfortable soft groan, and the entire refining process was finally over.

After carefully tasting the changes in his body, Lin Chu couldn't help but frown, although there were so many restrictions on this self-sacrifice technique, but every time he advanced a layer, the effect it brought was definitely worthy of the resources it consumed in terms of refining the body.

The previous bone refining of the Basic Cultivation Mind Method made the bones of the cultivators as indestructible as iron and stone, and the focus was on strengthening the strength of the bones of the cultivators.

The bone refining of the self-sacrifice formula is equivalent to adding various elements to the iron and stone re-circuit on this basis, and finally turning it into steel, which is not only further strengthened in hardness, but also makes each bone have strong toughness, which is self-evident, at least the ability to resist impact is more than doubled.

Moreover, these bones faintly gave Lin Chu a feeling of vitality, as if he was breathing.

The breath is long and instantaneous, nothing can be broken, and there is no way to urge.

This is a description of the effect of the self-sacrificing formula on the refining of the body at this stage.

Lin Chu was still a little skeptical about this description, but what he could be sure of was that even if his current bones were really broken, as long as a certain buffer time was given, these bones would grow and repair on their own, and there would be no need for any treatment at all, if there was sufficient spiritual power to provide, the recovery time would be greatly shortened.

Sitting down cross-legged with satisfaction, Lin Chu ran the basic cultivation method, and now, he could finally enter the fifth layer of qi refining.

The sacrificial formula still divides half of the aura, but now it is refining the meridians. The refining order of this self-sacrificing formula is always one step slower than the refining order of the basic mental method, as if the basic cultivation mental method is laying the foundation, and the self-sacrificing method is further consolidating the foundation laid well.

The remaining half of the aura began to slowly emanate from the meridians with the operation of the basic mental method, and finally it was not absorbed by the bones as soon as it was dispersed before, but set off towards the internal organs in the body and began to refine the internal organs.

Quenching the internal organs, the beginning of the five layers of qi refining.

......

When the moon was bright, it was already late at night.

Lin Chu stopped today's mental cultivation and prepared to rest.

However, before resting, he still has to figure out what the situation is on the green leaf list, why did he get into the top 100 for no reason?

Connected to the spirit brain instrument, Lin Chu did not click on the green leaf list, but first inquired about his credits, this green leaf list is ranked according to the credits, as long as he understands whether there is a sudden change, and where the change came from.

I see, there is such an unexpected joy.

The latest piece of news on the credit record made Lin Chu understand everything at once.

"Hahahaha......"

Lin Chu's irrepressible laughter came from the small building of the history department.
