Just as Hou Yiwei stated, the Demon is not friends with him and might be messing with his mind. Even if they are fighting against the same enemy, all of the guilds that came here are all fighting for the same prize. All of the guilds want to be number one in the Guild Raid Ranking as the prize is a 20% increase of experience points for three months which can stack.
Any experience boost reward is the goal for all of the guilds at this stage in the game. They need to have more experience points in order to get more powerful and get more levels. This is also one of the reasons why the Celestial Guild headed by Hou Yiwei has reigned at the top for so long.
