Just as in the first level of the Great Wilderness Grotto-Heaven, the metal walls surrounding this level were covered with several thousand totem beasts, most of them capable of flight. Only when these totem beasts began to move did everyone realize that the metal objects embedded in the walls of this grotto-heaven were by no means useless sculptures, but terrifying puppet battle constructs—taking the forms of all manner of animals and exotic beasts that no one had anticipated.
At this moment, the surrounding walls were like nests for these totem beasts. Animal-shaped puppet battle constructs flapped their wings and continuously pounced out from the metal walls, immediately engaging the knights, who were darting about like headless flies. Caught unprepared, the knights suffered casualties in an instant.
Each of these puppet battle constructs possessed strength close to that of a Black Iron Knight, and their numbers were immense. More importantly, they seemed almost impossible to kill. Even if they were smashed to pieces, the shattered metal would, in the blink of an eye, fuse and gather together again, restoring its original form and continuing to fight. The scene was exactly the same as what Zhang Tie had encountered in the puppet hall of the Blood Sacrifice Temple.
But compared with the current situation, that puppet hall had been like a tiny shaman before a great one, like guerrillas facing a massive army—there was simply no comparison.
In the blink of an eye, throughout the hundreds of thousands of square kilometers of the second underground grotto-heaven, the furious roars, screams, and cries for help of the treasure-seeking knights, the air-rending detonations of the animal-shaped puppet battle constructs, all kinds of tiger roars and dragon chants tinged with metal, and the multicolored radiance of Battle Qi collided and intertwined, shaking heaven and earth.
