After reaching his room, he kept meditating to increase his essence cultivation.
After entering human champion realm, levelling up his essence cultivation became harder, it took him three minutes to enter the first level and six months to enter the second level.
Right now, two month have passed, and he was still in level 2.
It wasn't like he was stuck in that level or something that has to do with him not being a genius, but the thing is, it seems like normal meditating would not help matters if he keeps on depending on it.
As for his martial art cultivation, which mainly has to do with the increase of his body physical strength, endurance, dexterity and his muscle strength, everything happened in a matter of years.
For level 1, he spent one year practicing the Crimson dragon art, while level 2 took a year and half.
During that night, his cultivation went on with the normal speed that it should and he got pretty tired of it.
