Review Detail of FlipFlopFckBoy in World's Best Martial Artist

Good story I admit, 600 chapters deep now I considering to drop this. The first 1-100 chaps is okay, and so the rest, while this novel lack of mainstream cliches, and this novel heavily based on nationalism which I dont even mind to care. When you read to somewhere around 200-300 you realized that MC is just a brute, he is progressing so fast that he became a Rank 7 just in 2 years. There are alot of talented people, which didnt even have any system, they progressing relatively fast, and train their fighting skill everytime. MC got system, his progress is fast, to the point his skill isnt actually up to pair with his rank. True MC can defeat or even kill someone who is rank higher than him. But their fight is extremely boring, MC just spam his not so good ultimate move, later on MC just spam mentality or mentalpower to the point self destructing his own mental power, no worry tho MC got system to save his ass. So 600 chapters deep, the story became so boring.
