The thing that he was most curious about was the nine revolutions cave. It was so big that Zhao Hai had to use a large number of liquid silver Flying Needles and more than ten days to fully understand it. The entire nine revolutions cave was like a huge underground world, but the Masters of this underground world were all snakes, not humans.
Of course, what Zhao Hai was most curious about were the little golden snakes. Zhao Hai estimated that there were close to 1000 of them. This number would only increase and not decrease. It should be known that these little golden snakes were all in the longevity stage. Nearly 1000 of them were in the longevity stage, and they had been protecting something all this time. This made Zhao Hai extremely curious.
