The Largest Bloody Black Gold Throughout History

"Oh..." Yang Dingtian broke the surface of the water.

"The water here is so warm!" Of course, this was just Yang Dingtian's feeling. The water temperature was still around negative ten degrees Celsius, but this temperature was already high enough such thatYang Dingtian felt warm.

The moment he surfaced, something shone brightly in front of him. He was in a pond whose surface area was similar to the unfreezing pond in the abandoned ore mine. The pond was also located in a huge cave, and the surroundings were covered with a layer of ice. It all looked crystal-clear like a crystal palace.

There was a hole in the wall of the cave and a passage behind that hole. The passage was covered with all kinds of crystal that were red and purple, all dazzling and beautiful.

The structure here was almost identical to the huge cave deep in the abandoned ore mine.
