If the man before me had been present when Lu Chuan treated Old Master Ye, he should know Lu Chuan's cultivation—he's a powerhouse at the Nascent Soul Realm.

"Mr. Lu Chuan, since you're a physician, you must know how precious these items are. As long as you're willing to answer a few of my questions, I'll offer these treasures to you with both hands."
Lu Chuan caught the Storage Ring the man tossed, extended his Divine Sense for a glance, and couldn't help but draw in a sharp breath.
