Chapter 451: Chapter 424: Demon Race City

Xu Fan held the Time Crystal Ball in his hand and said, "Luckily, I didn't put this thing in the treasure house."

"Otherwise, if I let Number One refine it, wouldn't it be a goner."

The Time Crystal Ball in Xu Fan's hand now was the core spiritual mine he would use to refine the upgraded version of his Time Hut in the future. Currently, the remaining spiritual mines were incomplete, so Xu Fan hadn't started refining yet.

"I don't know if the remaining spiritual mines can be traded on the stars in the Human Clan's Navigational Channel within the Vast Void Domain. Otherwise, I can only go to the Demon World to have a look." Xu Fan said.

This time, when Xu Fan wiped out the Moon Fox Holy City, he saw the foundation of the great clans in the Demon World and was truly amazed.

At the same time, in Xu Fan's mind, the treasure house and resources of the Demon Clan Holy City now had an equal sign.

"Master, the railgun has now arrived in the Demon World." Pu Tao reported.
