On the ground, the sounds of battle shook the sky and the earth. The Storm Cavalry of the Immortal Army began to chase after the cavalry and warriors wearing ghost masks, completely destroying them.
Although the knights and warriors summoned by the ghost face masks were also very strong, the difference in combat strength between them and the Storm Cavalrymen of the Immortal Army was too great. To those summoned creatures with flesh and blood, the Immortal Army was an unkillable monster on the battlefield. A warrior of the Immortal Army could easily destroy ten warriors of the same level as him in a head-on battle.
For the Immortal Army, their appearance could change at any time according to Xia Pingan's will, so there was no need to worry about people who had entered the Eternal Underground Palace finding out anything. More importantly, the Immortal Army's indestructible metal puppet warriors could be created by some powerful mechanical puppeteers.
