Just when the thick mud disappeared by nearly half a meter, something unusual suddenly occurred.
The original mud vanished, replaced by a hard surface.
This made Lin Yi's brow slightly furrow. According to common sense, the mud's thickness shouldn't be so shallow.
After all, this pond is eight to nine meters deep, and its mud depth should reach nearly two meters.
But now, it is clearly abnormal to encounter a hard surface when only half a meter in.
However, Lin Yi quickly figured it out; perhaps this is the reason he was searching for.
Sure enough, upon encountering the hard material, he bypassed it and continued working nearby.
In a matter of moments, this area had been completely absorbed clean by him, essentially lifting the pond over half a meter deep,
Yet apart from the central area and a long strip leading to the edge, the mud depth in other places exceeded one and a half meters, verifying his hypothesis further.
