Tomb Robbery: Being Fed Blood by Zhang Qiling at the Beginning to Stay Alive

The original characters of the protagonist who traveled through time in the opening chapter are all privately designed. It is strange that it is more like starting the story without reading the original work and reading a few clips to explain it. The protagonist is about to die at the beginning, and it's all up to the little brother to save him by feeding him blood. The protagonist recovers and the gold finger arrives in his account. The result is a plunder system, and he plunders from the little brother.
