While Xuan Yan carried out his mission, the Ghost Realm was making moves as well.
The Ghost Lord of the Ghost Realm had grown ambitious. He wanted to replace the Heavenly Dragon Great Emperor and become the Lord of the Four Realms.
He had closely followed the previous war between mankind and Tian. When he learned that frail mortals had actually relied on technology to contend against Tian, even driving a host of Immortal Soldiers and Immortal Generals into retreat, an idea sprang to mind.
Thus, he secretly dispatched two Ghost Envoys into the Mortal Realm to investigate this so-called technology.
However, as the two Ghost Envoys possessed ghostly bodies and lacked mortal identities, they were rejected by the rules of the Mortal Realm. They met obstacles at every turn and had accomplished nothing so far, not even knowing where the laboratory entrance was.
In the end, they came up with a plan and resorted to possession.
After learning the addresses of two elderly doctors, they successfully seized their bodies that very night and, after several twists and turns, arrived at the Experiment Base.
Unfortunately, the Experiment Base had nearly collapsed because of Zhang Xuan. All its achievements had gone up in smoke, and the project had no choice but to restart.
After entering the Experiment Base in the bodies of the old doctors, the two Ghost Envoys found nothing.
Only after hearing from a young researcher that the Experiment Base had been mysteriously damaged did they finally understand.
After discussing it, the two decided to lie low there. The Ghost Lord had given them a death order.
If they failed to obtain this technological method, they would return only to have their souls scattered and vanish completely.
Zhang Xuan had long since left the Experiment Base, finding it dull.
