Capítulo 166: Save for upgrading Allen or Use for upgrading the ether?

*Ding! Congratulations, you have won Upgrade Crystal from the Lottery Wheel. The item was sent to the inventory.

"Okay, an Upgrade Crystal. It's time to power up Allen once again." Mark was satisfied with the first reward. Since he planned to give the divine sword to Allen, it would make complete sense to upgrade his rank further.

Mark couldn't help but imagine how Allen might be able to kill Bai Xun whom Alina fell into a disadvantage during their last battle.

Unfortunately for him, the system decided to put brakes on his excitement, right away. Despite having 10 points of temporary luck, nothing could stop the disappointing notifications from the system. 

*Ding! Upgrading from rank-5 to rank-6 requires two upgrade crystals. So, the host must collect one more crystal. The system recommends the host raise the ether quality, instead.
