reasen

I just know them from their manhwa and not the novels. However, I read fanfics about them. I was more interested in the Library of Heaven path and martial peak. I plan to read them, though I am attacking them one at a time.

I just got the inspiration, and I am in a phase of reading Chinese novels. However, I thought it would be good that he has a skill that can evolve or make him reach the next level as he will step into the multiverse later

Kyoushin karate from God of high school.This martial art could become a menace if he could combine it with his wind nature justsus

Chakra is energy that is circulated using veins,nodes, and the dantain. He could compress the chakra to increase his chakra quality and purity, and that would allow his chakra to go through multiple sublimation or forms like from gas to liquid. Taking a step further, he could use or increase the number of nodes,creating a better circulation of chakra. If he learns Tsunade seal, then he could potentially seal or create stars(basically, chakra clusters in the nodes).The benefits would go well with his limitless growth and increase the density,quality, and purity of his chakra and give him more possibilities for his growth in terms of power and technique. However, the downside would be that he would need precise knowledge of his body and extreme chakra control and would become a bigger target for the akatsuki and the otsutsuki

Using the body replacement jutsu as base and law's room ability with his extreme chakra control, it should make it possible for him to replace himself or others with different objects from his surroundings, for example pebble,leaf or even air itself due to his wind chakra nature. The chakra control would also remove the smoke produced when using the jutsu, making others confused if he had used the flying thunder god technique. However, a downside would be that he can only switch places in a certain radius

I do not have a name for the jutsu. However, it would be an air bullet that has been compressed to the extreme, and its propulsion would cause the bullet to ignite due to the friction with the air. The longer the distance, the hotter the bullet becomes.Therefore, it makes it more dangerous. It could also be used in close range to attack the enemy without leaving any trace or hit pressure point with extreme precision. A variation could be in the form of a palm technique to attack the interior organs of the body

A genjustsu that attacks the nerves through a medium without the receiver knowing. He could then control the pain the opponent senses or use it on himself to remove pain. He could also create a genjutsu to target the cells of the body to rewire his target body
