Under the underground palace or the underground palace?
There were so many people present, and apart from Su Mo, no one knew that there was a fourth floor.
Everyone felt that the number of monsters that had appeared in front of them was already the limit of this sealed well underground palace.
However, only Su Mo knew that the first three layers were just ordinary seals that targeted low-level monsters.
For example, those Tier 6 monsters were all sealed in the fourth level of the underground palace.
As for the monsters above level 6, they were guardian the buildings on the top of the mountain.
According to the information given by the game panel.
Back then, in order to prevent the entire Lancang Mountain from being affected.
Most of the high-level monsters had been dealt with in advance.
The low-level ones were kept for research, but a lot of them were kept.
This was why Su Mo dared to open the fourth level.
