Chapter 873: Mysterious Gift Bag for Mythological TV Series!?

[The System is 60% upgraded. The expansion of Wrath of the Lich King is released.]

[Energy crystals are in a shortage, and the system is upgrading slowly.]

"What!?" Mr. Fang froze. Although he could only take a percentage of the income of crystals each day, he could calculate that the crystals and magic crystals that the shops earned was a very large number. But the damn System claims that it is in shortage of crystals!?

Seeing the system upgrade progressing as slow as a turtle and had almost stopped, Mr. Fang was at a loss for words.

At this moment, Mr. Fang received a new task.

[System Upgrade Task: Acquire Many Energy Crystals

Task Description: Be a truly excellent shop owner and earn as much money as you can!

Task Reward: Mysterious gift bag of a mythological TV Series (contains the TV Series activation right and a treasure from it)]
