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.
