Professor Cao, Professor Zhou, and the others continued on their journey.
They traversed the corridor.
From this new corridor, no more murals appeared.
It seemed that the legend of Sima Pi ended once they entered the Immortal Road.
Perhaps the ancients who painted those murals had also no clue about what Sima Pi encountered after he entered the Immortal Road.
They passed through the corridor.
Suddenly, the space in front of everyone opened up.
An unprecedentedly massive soluble cave appeared before them.
This underground soluble cave was like nothing anyone had ever seen before; was the Zombie soluble cave that could accommodate tens of thousands of coffins large enough?
But compared to this place, it was still inferior.
Here, the space was at least ten times larger than the Zombie soluble cave that Professor Cao and the others had seen before!
