Before that...
Leng San walked into a small cavern behind the curtain of the waterfall, not daring to be careless because this place was extremely old. It also vibrated nonstop from the impact of the waterfall. Moreover, Leng San was most worried about a possible mechanism.
But after a while, nothing was found. His pace was unconsciously accelerated due to his worry for his comrades. Finally, he found the end of the tunnel... It was similar to a hall, the size of an ordinary bedroom. It was not so large. What was shocking were the ancient characters around it and the altar in the center of this hall.
On the altar was a fist-sized pearl...
It was none other than the Serpent Pearl that Leng San had been looking for...
The young man froze for a moment, as he could feel that the atmosphere around Leng San was quite familiar, as if he had experienced the same atmosphere before. The young man recalled the Undersea Secret City from last year.
