If I turn the old man into a low-level zombie, not only would Lin Tian's identity be completely exposed, but the old man would be doomed as well, so he had no intention of doing that.
Lin Tian controlled the zombie blood to pass through the skull, along the back of the head, down the spine, and into the thigh bone. During this journey, Lin Tian carefully controlled the zombie blood, not allowing it to erode the surrounding bone marrow tissue.
Mr. Yun is just an ordinary person, and the zombie blood is extremely domineering; the old man certainly couldn't withstand the destruction of the zombie blood, so Lin Tian had to be careful.
As soon as the zombie blood reached the old man's leg, the yin energy surged again, and Lin Tian became more certain that his method was feasible.
