CHINESE LIGHT NOVEL WHERE IN A TRIAL THE MC JUMP FROM TRIAL WORLD TO TRIAL WORLD AND BEAT ALMOST EVERYONE AND AT THE END HE TOOK A GIRLS ARMOUR. HE GOES INTO THE TRIAL ON THE WEAKER SIDE OF THE PARTICIPANTS AND IF I REMEMBER CORRECTLY HE MAKES SEVERAL BREAKTHROUGHS WHILE IN THE TRIAL AND ALSO I THINK ONE OF HIS POWERS IS A STRONG BODY OR IS ABLE TO CONTEND WITH PEOPLE WITH A STRONG BODY VIA A TRANSFORMATION OF SOME SORT. ALSO I REMEMBER THAT HE IS BEING MONITORED BY THE BIG WIGS OF THE SCHOOL OR ACADEMY THAT THE TRAIL IS FOR.
So many novels fit this, Heaven's Devourer, Nine Star Hegemon Body Art, The Great Ruler. just off the top of my head. Im sure there are more.
Your description is too standard for any cultivation novel, also did you hit Caps Lock? hmm its kinda similar to Perfect World
Anything else about it? Right now it could be any cultivation novel at all. I would even use your description to describe the genre as a whole.
Thats like google searching for specific dog race but you only write, its was a dog, had fur, claws, a tail, was brown, had teeth and barked a lot, he had an owner and lived in a dog house...
