World's Strongest Martial Warrior

The extreme sports lover Peter Parker got into an accident when he went hiking in some isolated mountains. 
As he opened his eyelids with effort, what he saw was hundreds of training tools hanging on the walls while he himself was lying on the floor. What happened to him?
He then realized he had crossed to a martial continent, and the original owner of this body was Jeff Parker, a useless brat born in the Ghost Blood City, a military trainee of the Parker family specializing in mystic arts, and the only son of the patriarch of the Parker family. 
His father loved him so much that he sacrificed his life to gain an opportunity for him to enter Fierce Lions Military Academy. 
But he was looked down upon by all the other students and cheated by his own uncle and relatives.
Nobody knows that current Peter has a mysterious system that helps him upgrade from time to time.
Taking a step, the Basic Fist technique gained. Experience points achieved: 10x100
 Throwing a punch, 10 x 100 experience points earned! His technique upgraded to Blue Rank.
Taking a pill, his cultivation level rocketed even faster than the rocket!
Sword technique is hard to learn? Being an alchemist is hard to realize? 
For him, all of this is nothing. He could do all of them on his will and at any time!
