Bone Temperature

Lin Xu was 15 years old. His parents died in the mist. He touched a bone under the floor of the main room - it was still warm after seven years. In this world, spiritual energy is exhausted, and monks rely not on their Dantian but on their bones. If the bone temperature is high, it will be strong; if the bone temperature dissipates, it will turn into "bone white" and remain dead forever. He thought he was useless until he discovered that the bone could "eat" the warmth of other people's bones. Ah Jiu waited for him at the door for seven years. The city lord is at the door and wants to open it. There is no system, no golden fingers, but there is a bone that can "eat" the temperature.
