To be honest, Zhang Feng found it absurd.
Because it was clearly unbeatable.
But at this moment, a book fell off the nearby shelf, landing open, revealing a photo inside.
"What's this?"
Da Gao, curious, picked up the photo.
Zhang Feng also looked over and saw a picture of four strong men.
On the back of the photo was a phone number.
"I have no idea what it is either." Zhang Feng couldn't make sense of it, but he also picked up the book.
Flipping through it, there were several pages with diary-like content.
It roughly stated.
These four people were professional adventurers with great skills.
Then three years ago, Da Gao happened to meet them while playing in the mountains.
After getting along well, they naturally became friends.
The phone number on the back of the photo belonged to their leader.
"I reckon this is the external aid mentioned in the task."
