Tomb Raiding: Blood Devours the World, from Pingshan to the Bronze Gate

It feels very poisonous. Not explained clearly. There is a problem with the protagonist's character setting. I feel that based on his setting, he could just find a village to bite random people, transform them, and then go to the tomb. And the numbers are hard to understand. With four times the number of ordinary people, you can easily defeat a bunch of tomb robbers with guns. All I can say is that I won't act anymore. Is this a setting of invincibility? It can be brought back to life, and there is a lifespan limit. Not explained carefully.
