Wang Qing is a supporting character. He wants to become an immortal and plans to find the real protagonist and hitch a ride. As for the real criteria for him to judge whether the other party is the protagonist or not, there are only two criteria: the first one: whether he is willing to give him benefits; Let him become an immortal.
Article 2: Can I be beaten to death?
"The one who I can't kill, who can also give me benefits and send me to become an immortal, is the one who is destined for destiny, the decisive choice of the era, and the protagonist of this world! I will become his steadfast partner and most reliable Taoist friend! Join hands with Feixian and stay with us for a long time!" - Wang Qing.
