Back when Joe Ga went to rescue Lu Jun, he encountered Dorian, who was forced to work for his life.
Then Dorian betrayed them and helped kill a group of mercenaries, after which they went together to kill the eldest son of the Mori Family, and also took out an Englishman...
After going back and checking, they got a 'Mediterranean smuggling map' and a dozen blank passports. At that time, Dorian found a wallet from an Englishman, inside which were a room card for a hotel in Juba and a bank vault key.
That thing had been left by Joe Ga at the house in Ad-Damazin because he really didn't have the time to go and play a treasure hunt game.
Looking at Aaron's curious face on the other side of the phone, Joe Ga shook his head and said, "I don't know if you're lucky or not, I killed an Englishman, got a hotel room card and a bank vault key..."
Aaron, hearing this, excitedly asked, "What was the guy's name?"
