Right now, the will of the feathered serpent was still present, so Lin Yao had two options.
One option was to obliterate the feathered serpent consciousness and allow his own consciousness to settle in it, just like the angel spirit essence. This was the safest option. By then, the feathered serpent would be Lin Yao, but Lin Yao would not be the feathered serpent.
However, there were many advantages and disadvantages as well. A sacred tree could only host one main soul. After the soul settled into the feathered serpent, it would become the incarnation of Lin Yao, which could not be changed. At the same time, if the feathered serpent was destroyed, Lin Yao's soul would also suffer severe damage, which was similar to damaging part of his soul.
