Carefully raising one foot, Lin Chu tried to take another small step forward.

The violent aura storm blew from behind him, and Lin Chu almost fell to the ground with a stagger, but he hurriedly thrust down the shield that was blocking his backhand behind him, and fixed his body.

It seems that this is the limit at present, Lin Chu looked at the rainbow more than twenty meters away in front of him regretfully, slowly squatted down, hid his whole body behind the shield, and then squatted in an awkward posture to complete the turn.

Standing up and raising his shield, Lin Chu began to walk back against the strong aura at the bottom of the Rainbow Valley.

It had been a year since that time he absorbed the Iron Eater Beast, and Lin Chu's cultivation was still at the fourth layer of Qi refining.

This layer is an extremely special level, and it is the only level in the cultivation realm that everyone does not want to complete quickly, but instead expects the process to be extremely slow.

The fourth layer of qi refining is a crucial level for true spiritual root cultivators, this layer is mainly to familiarize the meridians with spiritual power, broaden the meridians and make the meridians more stable in the continuous erosion of spiritual power, and lay a better foundation for future cultivation.

Because the longer the spiritual power is washed, the better the meridians will be broadened, so it will be used to promote the absorption of spiritual energy and the use of exercises in the future.

Generally speaking, cultivators hope to stay at this level as long as possible, but here it does not mean that it deliberately does not cultivate and drags on for a long time, but refers to the time when the spiritual power washes the meridians.

Otherwise, if you don't cultivate, the stay time in the fourth layer of Qi refining can be extended indefinitely, but the meridians have not changed, so it is useless at all.

In the academy's sufficient aura cultivation environment, being able to stay in the fourth layer of qi refining for a year can be regarded as a good result for the rest of the cultivators, and this kind of qualification is already considered to be more than enough.

However, Lin Chu was not happy, because of the sacrificing technique like a bottomless pit devouring spiritual power, his cultivation could not enter the fifth layer of qi refining, and his meridians were currently running spiritual power, and he no longer felt any swelling when running his spiritual power, which proved that his meridians were almost tempered.

Originally, it should have been logical to enter the fifth layer of qi refining and start refining the internal organs of the body, but at this time, the spiritual power running was completely absorbed by the body sacrifice technique, and not the slightest trace could enter the five internal organs, it seems that if you don't use the body bones to quench all the bones with the body refining technique, you will not be able to enter the fifth layer of qi refining.

But, hey, this bone refining has only been completed by a quarter so far.

This is still the result of Lin Chu's best efforts.

He is doing a business that shields the aura and allows the students to enjoy the beautiful scenery of the rainbow with peace of mind, but the business is getting worse and worse, and he can't get a few spirit stones into his account every day.

Falling to the bottom of the rainbow valley, this year, he is a surprise raid once a month, so that the wild mandarin ducks in the academy have listed this place as a tryst forbidden place, and when he went again last month, he didn't find the wild mandarin ducks all night.

As for the iron-eating beasts in Dongliu Mountain, he went to sweep again last month, and the reproduction ability of those iron-eating beasts was not bad, and he contributed more than 2,000 corpses to him, this time he didn't hold back, and directly exterminated the group of iron-eating beasts.

And Lin Chu's current behavior of wanting to get close to that rainbow had nothing to do with his cultivation.

If you want to talk about cultivation, at present, for him, it is the best effect at a distance of fifty meters from this rainbow, it is closer, although the aura is more sufficient, but resisting the aura Gangfeng requires him to use his own spiritual power to fight, and the absorbed aura is not as much as it consumes, let alone cultivation.

The reason why he tried to go inside was just for the little bun.

Next month is Meng Danchen's birthday, and no matter what others say, they have helped themselves so much, no matter what, they always have to express it.

This was Lin Chu's idea when he learned about Xiao Baozi's birthday, but with Xiao Baozi's conditions, Lin Chu, who should have been poor and white, couldn't think of what gift to give her when he thought about it, until he remembered that Xiao Baozi said that he liked the rainbow of the academy the most, so he had an idea and wanted to help her touch this rainbow with her own hands.

This is why Lin Chu made a move to break through the aura of the gang.

However, it turned out that he still thought too much, the rainbow in this academy was really like what the seniors said, at least the foundation building period cultivation was needed to get close, and the general foundation building period was barely approaching, and it would be relatively easy for Jindan stage cultivators to enter from the air.

......

Lin Chu, who walked out of the valley, lowered his head and opened the communication bracelet, hey, there was still no news.

When he first entered the fourth layer of Qi refining, Lin Chu was full of longing for the academy's tasks, and in his beautiful fantasy, the day was approaching when he would complete the academy's tasks and have a lot of cultivation resources in his account while obtaining credits.

However, the facts once again dealt him a heavy blow.

There are very few tasks that can be done by the fourth layer of qi refining, and a bunch of people have taken them almost as soon as they are released.

In addition to the students of the fourth layer of qi refining, there are many teams above the fifth level of qi refining who will easily take over the task of the fourth layer of qi refining, after all, credits are rare.

Even if it is a task that limits the fourth layer of qi refining, there are many competitors, and the other fourth layer of qi refining in the academy will take on the task, or they have a skill in some aspect, such as having a good attainment in the formation, or practicing the rejuvenation technique very well, and then join the students of a fixed team, and the task is completed with the help of the whole team.

As a novice without a team, even if Lin Chu took the task, the completion speed was definitely not as fast as others, and after running two empty trips, he gave up the idea of taking the task by himself.

As for joining the team?

From time to time, someone on the intranet of the academy posted news about recruiting team members or forming a team, but Lin Chu's application was basically lost, and he didn't even receive a reply.

There are no teams on the fourth level of Qi refining that are willing to recruit, not to mention that Lin Chu still has the title of "History Department", and without receiving any mocking reply, it can already be said that the quality of the students in the academy is good, after all, most of them are girls, and there are not so many boring people who will deliberately reply to humiliate him.

There are only a few people he knows well in the academy, and Yu Yingnan and Meng Danchen are both people who have a fixed team early on.

Not to mention the other two people in the history department, they were still staying at the third layer of qi refining, after all, those two had just started cultivating when they entered the school, and they were really weak spirit roots, and they had cultivated to the third layer of qi refining for more than two years, which was already a very gratifying achievement for Gu Tiancun.

As a last resort, Lin Chu could only post an advertisement post in the mission forum section with "Professional Meat Shield, Super High Defense", hoping that some teams would be able to contact him to participate in tasks that needed to be defended.

It's a pity that even if he reduced the harvest requirement to half of the normal task, there was no team to contact him, and occasionally one or two teams found him for various reasons, and after learning about his cultivation, they were immediately out of news.

This year, he has not completed a single task.

It seems that it will not work without magnifying the moves.

Lin Chu gritted his teeth and thought, his face was hideous, he punched the rock hard, and strode towards the dormitory in the splash of rubble.

Returning to the dormitory and turning on the spirit brain instrument, Lin Chu began to carry out the plan he had hesitated for a long time.

If you want to cultivate quickly, you have to be ruthless with yourself.

While cheering himself up, Lin Chu wrote the first sentence with a trembling hand: That night......

That night, a post appeared on the college's gossip forum that caused a lot of shock.
