This time, not only did he want to visit the Extreme Joy World, but he also wanted to investigate a matter, namely, the disappearance of the Rotten Poison Ghost's sealing item.
It was an evil spirit that Su Ningyu had sealed with great effort, but when he went to look for it later, he found it gone.
The Sun Nine-Patterned Golden Coffin could prevent evil spirits, even ghost servants.
If ordinary martial artists happened to pass by, completely ignoring the terrifying battlefield left around, and foolishly opened the golden coffin... then, the Rotten Poison Ghost should have been released.
However, as of now, Song Cheng had not detected any ghost servants of the Rotten Poison Ghost, which meant... the Rotten Poison Ghost might still be in a sealed state, just taken away by someone.
The Northern Border would become his temporary refuge, he did not want such a great hidden danger nearby.
What is a hidden danger?
Anything unclear is a hidden danger.
