This was the soldiers' first time conducting battle underground. Before commencing, they had already memorized their part of the map. They planned to sneak into the tunnels and attack the demons before they had time to detect their presence.
Inside the tunnel, the first battle occurred at the Green Nightmare Army's area. The intense battle saw the unprepared demons suffer heavy losses. Subsequently, each of the individual teams encountered resistance from the demons.
Ji Fengyan led a team of over 40,000 and encountered their first wave of demons after traveling several kilometers deep.
Those demons had detected the approach of the human army and had amassed their own troops and launched their defense.
Chaos ensued within the vast tunnels. Ji Fengyan and Bai Ze were at the forefront. Their surging energy influenced the rest of the team, and the Wolf Smoke Regiment rallied strongly. They plowed into the demon army and advanced steadily.
Although this was the Wolf Smoke Regiment's first real battle, their ferocity and prowess left the Blaze Army soldiers dumbstruck.
As the demons attacked, none of the soldiers retreated. They braced against the surging demons and forged on mightily.
The tally of enemy deaths continued to climb.
Being underground, the boundaries of the tunnels constrained the battle. The demons had wanted to use the complexity of the tunnels against the human army, but after half a day, they realized the soldiers appeared to know the tunnels like the backs of their own hands. No matter where they had hidden, those soldiers could sniff them out easily and give them a sound beating.
The thick smell of blood permeated the dark tunnels where death and blood intertwined.
The tunnels were vast and comprehensive with multiple forked pathways. Whenever Ji Fengyan encountered a diverged path, she would allocate a portion of her men to one track while she led the rest forward in the other.
This was an encirclement attack. Over 260,000 soldiers had entered the tunnels from five different entrances. They surged in like gushing water, spreading throughout the entire tunnel network. They covered all escape routes and forced the demons back into their lairs, where they then massacred the monsters.
Constricted by the tunnels, the high-level demons completely could not exhibit their full powers. Otherwise, they might have blown the entire tunnel network to bits, bringing both the human soldiers and demons along in death.
The demon-built tunnels had become the key to controlling them.
As wide as each tunnel was, space was still limited. The vast number of demons ended up in a bottleneck situation where only the foremost demons were able to attack. Meanwhile, the flying demons were completely useless underground.
In the end, a large number of demons were stuck at the back and could only stand and witness their own kind before slaughtered at the front. They also watched helplessly as the killing gradually inched towards them.
On the other hand, the 260,000 human soldiers had been spread throughout the tunnels and seldom encountered such a difficulty.
Ji Fengyan had assigned Linghe, Lu Shaoqing, Yang Jian and the rest to lead various teams. Each of their teams chased after and surrounded the demons, doling out death and destruction in all directions.
