The Black Rock Tree Monsters at LV7 underwent a significant ability upgrade, their activity range reached a hundred kilometers, and their numbers expanded from 1500 to 4000.
Having just achieved a breakthrough, the Black Rock Tree Monsters that had been waiting promptly joined the construction site, working alongside the construction team members to accelerate the building of the wall.
The wall, which had already been built to three meters high and encircled the entire Niuding Mountain, saw its construction speed greatly increased as a large number of Black Rock Tree Monsters entered the interior of Niuding Mountain, building partition walls in the designated areas.
On the 10th day, the wall reached a height of 10 meters, and the partition walls were initially closed off at a height of 4 meters.
