Chapter 406: Second Confrontation

Yan Fei stored the eight large boxes into the Universal Space and immediately noticed that the number of Drone Upgrade Essential Items had become 5, which was an increase of 4 from before; he could hardly believe his eyes. It should be known that every time he had obtained a Drone Upgrade Essential Item in the past, he had to go through a lot of hardship, even risking his life. But never had he experienced such simplicity as today, acquiring more than two Upgrade Essential Items at once.

However, this was good news for Yan Fei because it would accelerate the upgrade speed of his Drone Avatar. Yan Fei calmed his excited emotions and checked the Auxiliary Brain again, only to see that the display really read 5/10 Drone Upgrade Essential Items, confirming that he truly had obtained four Drone Upgrade Essential Items at once.
