The sword on his hand right now is a treasure that swordsman would love to had, but he wasn't that stubborn, he then use his Saint Qi to try and destroy the sword.
The spearman sensed the powerful Qi emitting from behind him and realised that his comrade have decided to forsaken such treasure, he knew the reason for this is because of him.
The two of them are sensitive towards Saint Qi, they also known each other for a long time, they could sense and estimate just how much Saint Qi in each other's reserve.
