This warehouse was He Qingyuan's secret place, and it was not accessible except to those who deeply trusted by He Qingyuan.
He Qingyuan trusted Liu Chen because Liu Chen possessed the Scythe of the Grim Reaper, which had enough value to be leveraged.
Liu Chen still didn't know how much He Qingyuan really understood about the sacred land of martial arts. Did he simply think that possessing the Scythe of the Grim Reaper and a map would grant him entry into the sacred land?
Did he even know about the existence of the Everlasting Bronze Mirror?
"Brother Liu, let me be honest with you, our search for the sacred land of martial arts is almost certain," said He Qingyuan. "Of course, if you would join us, we wouldn't need to worry about our success. At that time, all the treasures we find will be ours."
