Standing on a mountain range, Wang couldn't even see the end of the mountain.
But he could feel this challenge was not easy at all.
After having dealt with the situation between the bandits and the Chen family, Wang came back and focused on improving his movement techniques.
It was easy to obtain some from the collecti9n he had gotten in the period he challenged the third floor.
Over time he didn't bother to practice them, but to pass the fourth floor he had to improve every aspect.
Over two weeks since then, he focused on improving himself and then went under the sea to challenge the original temple again. His speed had increased a lot and even the challenges on the fourth floor seemed ti be bearable.
The fourth floor seems to be some kind of threshold as such to pass he was required to do more than just fight one opponent.
