Although Yang Jian had successfully separated the Road of Yin and Yang, preventing supernatural forces from invading reality, much effort was still needed to fully perfect the plan.
Zhang Xianguang's concept of layer upon layer of Ghost Domains was correct.
Because with every additional layer, this world gained another measure of safety.
Therefore, Yang Jian needed to establish as many Ghost Domains as possible along the Road of Yin and Yang. It was an enormous undertaking, and the cost was equally immense.
For some time afterward, Yang Jian and Zhang Xianguang never left the third room.
The two of them continuously devised and refined Ghost Domains before bringing them into reality.
It could be said that whenever a new layer of Ghost Domain appeared, it represented the culmination of wisdom and painstaking effort.
However, while constructing new Ghost Domains, Yang Jian and Zhang Xianguang also encountered some incomprehensible supernatural phenomena. These phenomena appeared neither in supernatural places nor in reality, but on the Road of Yin and Yang itself.
Because the two of them would occasionally see strange figures wandering along the Road of Yin and Yang.
Yet whenever they tried to deal with those things, the strange figures disappeared again.
"There may be a vicious ghost wandering the Road of Yin and Yang, or perhaps the Road of Yin and Yang itself is a ghost," Zhang Xianguang speculated.
Yang Jian said, "The Road of Yin and Yang is a buffer zone between the supernatural and reality. Don't you think it resembles the Ghost Domains I created? Is it possible that the Road of Yin and Yang was once created by some Ghost Tamer to stop the supernatural world from invading reality? We are merely following in our predecessor's footsteps and widening this road."
Zhang Xianguang pondered for a moment.
