Growing up parentless, Shi Yan, who was left with a large amount of inheritance money, bore a general disinterest in life. The only times he felt alive was when adrenaline coursed thorough his veins. He quickly found that extreme sports, bungyjumping, cave diving & skydiving, gave him the biggest kicks. The bigger the adrenaline kick, the closer he was to death, the more alive he felt. Waking up in a pile of dead bodies in an unknown land, after a diving adventure had ended disastrously, he quickly realizes the body he now possessed was not his own. Follow Shi Yan as he explores this new world where danger lurks around every corner, and death is only a breath away; a world in which Shi Yan could not feel any more alive.
After a fight, Shi Yan had entered the Second Sky of Sky Realm directly.
Through the fight with Situ Jie and Zou Yue Feng, his confidence was boosted, as he knew that the two Spirit Realm warriors couldn't kill him. Thus, when he went with Yin Hui, he wasn’t afraid of the other anymore. Yin Hui could be a decent match at Shi Yan's level, which could bring him to another height.
So, when he talked to Yin Hui, he didn't need to fret, and he could say anything he wanted without worrying that he would displease Yin Hui.
The reason why he chose to carry out the battle in front of the Silver Stone Fort was to show his competence to all the members of the Sea Tribes. This would make those people realize his real capacity that could help him counter any strong warriors from any races. He could even win.
