The next morning, the whole school was in a hurry, and you were all the lecturers and professors who were usually high-minded, and all of them had to participate in today's cleaning activities.

But when Yu Hao and the others came to the vicinity of the confinement room, they were immediately stunned.

In the past, they used to pass by here during classes, because the pressure here is too great, so most people are reluctant to come, and even when they pass by, they will walk around, so the neighborhood is not spotless, but it can be regarded as clean.

But after a winter vacation, the crystal-paved floor tiles were covered with blood and disgusting liquid, not only on the ground, but also on the walls of the square building of the confinement chamber, as if a fierce battle had been fought.

"What's going on? Why is this place the same as a slaughterhouse? "There was a disgusting smell in the whole place, and I don't know if this was deliberately done by the principal or if something really happened during the winter break.

"Huh? There are traces of battle! Yu Hao glanced at it a few times and keenly noticed that there were some scratches and chips in several places on the floor tiles.

You must know that the ground of the entire school is paved with a very solid natural ore, Yu Hao has tried, even if he uses the Zigang heavy sword to slash with all his strength, he can't leave a trace on it, I heard that if you want to destroy the facilities in the school, you must at least have the strength of the senior level or above.

"Did something escape from the confinement room during the winter break?" Yu Hao thought about it, it would be more likely.

"Well, no matter what happens, let's start cleaning, this area is not small, and a whole day will definitely not be enough." Yu Hao reluctantly took out the mop and began to clean up the blood stains on the ground.

The task they were assigned was an area of 300 meters around the confinement room, at the beginning, because the distance was still relatively far, so the oppressive force was not particularly obvious, and everyone's physical strength was far beyond ordinary people, so the speed was very fast, and most of the tasks had been completed in most of the day.

But when they were only about a hundred meters away from the confinement room, finally someone began to lose it.

Cheng Jing's mental power is quite strong, but her physical fitness is the worst, and that breath oppresses and destroys not only people's will, but also causes serious suppression to the body.

It didn't take long for Cheng Jing's hands and feet to tremble slightly, and even began to lose her strength, she felt like a person with a serious fear of heights standing on a 10,000-meter-high cliff, and even fainted almost at any time.

"Cheng Jing, why don't you go to the side and rest first." Yu Hao saw Cheng Jing's sweaty appearance, it was obviously impossible for her to continue working in this state, if she continued forcibly, I am afraid that she would really be devastated by this breath and coma in a while.

Although Yu Hao's state is much better than hers, it is not easy, he seems to have come to a haunted house full of resentful spirits, his ears are full of ghosts crying and wolf howling, and the pressure on his body is like being in a gravity room, and his hands and feet are as heavy as cement.

"This is really a different kind of training!" Yu Hao stimulated the qi and necromantic power in his body, and used his energy to resist this kind of coercion, which can resist to a certain extent, just like Bai Mengmeng said, this can be regarded as a disguised cultivation.

Seeing Yu Hao's approach, everyone followed suit, Li Yixiao's true yuan power, Fang Ruoyuan's nine yin divine power, Luo Xiao's rune power, Wang Xiaoyu's internal force, and Xu Yun's elf power...... The most amazing thing is Shi Qiuyi, although she usually looks inconspicuous, she seems to have different advantages in this regard.

The string of Buddha beads on her wrist emitted a golden Buddha light, resisting all the negative effects outside, judging from her expression, she was almost the most relaxed, and it was much more difficult for others to resist.

"It's almost three times the force of gravity here." When he came to the range of about fifty meters of the confinement room, this mottled coercion began to become stronger again, and even Yu Hao seemed to have a lot of difficulty, according to this situation, it was definitely a very difficult thing to clean the outer wall of the confinement room.

......

"Mom, I'm tired!" The first day's clean-up was finally completed by five o'clock, and they had finally cleaned the perimeter of the confinement chamber, leaving only the walls outside the confinement room, and everyone was almost emptied of their bodies, and as soon as they returned to the dormitory, they collapsed on the couch.

"Damn, how did we get so unlucky to be assigned to such a ghost place?" Xu Lang shouted dissatisfiedly.

"Like, this kind of place should be cleaned up by juniors and seniors, it's too difficult for us, right?"

"Don't mention it, I don't even have a little oil and water, I just heard on the way back that a guy in Class 11 found a Condensing Pill in the area they were cleaning, this is a good thing, it is a treasure for the students of our Immortal Cultivation Academy!" Li Yixiao said enviously.

"Hey, look at our hellish place, there are no good things, just like the group of demons and monsters in the confinement room who don't know what they are."

"Okay, don't complain, at least everyone's physical fitness has strengthened a lot this day, isn't it?" Yu Hao comforted.

Although everyone knew that Yu Hao was comforting them, what he said was not wrong at all, the effect of cleaning the confinement room on this day was almost equivalent to their cultivation of immortals for half a month, and everyone had a significant improvement in mental strength, physique and strength, especially a few people who had been strengthened by bloodline, their progress was even more obvious.

The biggest advantage of bloodline strengthening is that it can develop a part of the body's potential, but this part of the potential needs to be triggered by external forces, and this day's stimulation just played such a role, and the average physical fitness of Li Yixiao and the three of them increased by almost a hundred points!

Thinking of this, everyone's hearts are a little more balanced, at least other people don't have such gains, right? The number of people who can pick up treasures is only a small part, and it is really good to directly improve their strength.

"Okay, everyone take a good rest, I have to catch up with the progress during this time, and make all of you bloodline strengthening potions before the first monthly exam!" Yu Hao rested a little and returned to his room.

"What really happened during the holidays?" After returning to the room, Yu Hao was still thinking about this problem, judging from the situation around the confinement room, there must have been a fierce battle.

But isn't fighting in school a quick way to recover from your injuries? Why is it like someone is seriously injured or even killed?

The school's secrets seem to be growing......
