This string of telephone numbers.
Although unfamiliar, Du Wei glanced at it and recalled what it was all about.
The first time he used the Joker Card to enter the dream and faced the Demon Nun, Ryan had called him.
It was after that.
That the contact between Du Wei and Ryan was resumed.
Although they could only communicate through phone calls in their dreams.
And this string of numbers had remained in Du Wei's phone call history ever since.
Only.
He had tried dialing it in the real world.
But what seemed to answer the phone was an Evil Spirit.
That was a long time ago.
At that time, Du Wei was in great need of Evil Spirits, or rather, minions.
He had even told the other end of the line his home address, yet until his psychological counseling clinic was destroyed and he moved houses, that suspected Evil Spirit existence had not sought him out.
Latter on, as more and more reliable Evil Spirits appeared around Du Wei, he gradually forgot about that existence.
