Yan Fei knew that the Upgrade Essential Items for the Drone were among these items, so he didn't mind the filth and took out a stick to rummage through the goods. Then his eyes caught sight of a peculiar object. Most of the items here were gold, silver, and jewels, but among the dark sewage was a silvery-white cylindrical object, which was conspicuously out of place with the surrounding artifacts.
At that moment, the Auxiliary Brain sent a message, and an image of a silvery-white cylindrical object appeared in Yan Fei's mind—it was identical to the object he had just seen. It turned out to be one of the Drone Upgrade Essential Items.
Yan Fei reached out and grabbed the cylindrical object, holding it in his hand. He found that its surface was incredibly smooth. It had been submerged at the bottom of water for hundreds of years, but when the dirt on it washed away, there was no sign of corrosion, and it looked as shiny and new as ever.
