Xie Ai didn't dwell on that thought because of an incoming attack. Again and again, the skills of the other person surprised him so much that he could hardly concentrate. Thankfully, the steps to follow to use the card weren't too difficult.
Aside from that, he even learned that he had been punished by the instance rule to stay here for several years as an NPC without a hint of getting out of there. Then, he would return to the resting station for several days. The card even mentioned the room address that he had rented and urged him to renew his rent the first thing he returns.
Several things were written in a clustered manner, but he felt like something was still missing. But he didn't have time to ponder about it anymore as he first used the skill card.
