This is the first time that soldiers are fighting underground. Before the war, they have clearly remembered the distribution map of the underground. Before the demon clan realized it, they had already infiltrated the tunnel and were ready to take a surprise.

In the tunnel, the first encounter took place where the green nightmare army was located. The battle was fierce, and the unsuspecting demon clan was caught by surprise. Then each team successively encountered the resistance of the demon clan.

More than 40000 people led by Ji Fengyan met the first wave of demon clan after several miles in the tunnel.

Those demon clans have obviously sensed the arrival of the human army, and began to gather forces to fight back in the tunnel.

There was a scuffle in the tunnel several meters wide, and the monsoon smoke and Baize rushed forward, which affected the morale of the whole team. For a while, the wolf smoke army was overwhelming, directly pressing the demon army, and moving forward.

Under the bloody battle, the soldiers of the wolf smoke regiment joined in the real battle for the first time, but their ferocity made the soldiers of the burning army on the other side look stunned.

Under the influence of the demon clan, no soldier retreated, and they directly fought against the dense attack of the demon clan.

The number of enemies killed is on the rise.

Hesitation is to fight underground, and the scope of the battlefield is limited. The demon clan wants to fight against the human army through the complexity of the tunnel. But half a day later, the demon clan suddenly finds that no matter how they hide and avoid, those soldiers seem to have been clear about the terrain here, and there is no confusion at all, even if the demon clan They took the opportunity to hide everywhere. They also had a way to detour and directly give the demon family a head-on beating.

In the dark tunnel, full of a strong smell of blood, death and blood intertwined at this moment.

In the whole tunnel, there are many branches at every intersection. While Ji Fengyan leads the army to move forward, at every intersection, he will divide his forces into another channel.

This is a campaign of encirclement and suppression. More than two hundred and sixty thousand soldiers enter from five main entrances respectively. After that, they will spread like a flood to all channels in the tunnel, until they block the front road of the demon clan, force them back to their nests, and then destroy them at one stroke.

Because it's in the tunnel, the high-intensity lethal attack of the high demon clan can't be used at all, otherwise, it's not to say that the human army will be buried, for fear that the whole tunnel will collapse, and the demon clan will be swallowed.

The tunnels made by the demons themselves now become the key to limit them.

Although each tunnel is very wide, there is a certain range in how wide the tunnel is. Even if there are more demons in the tunnel, there is no way to use them. In addition to the demons at the top of the front can attack, it is difficult for the demons at the rear to hurt the human soldiers, and underground, the flying demons are useless.

A large number of demon clans are blocked in the rear in the form of tunnels, and only the most front demon clans can be seen to be slaughtered one by one, and the bloody killing also moves backward.

On the contrary, it is the human soldiers who have scattered 260000 people around the tunnels, and there are few cases of military hoarding.

Ling He, Lu Shaoqing, Yang Jian and others were sent out to lead the team by the monsoon smoke. They took part of the soldiers to chase and intercept the demons in the tunnel, killing all directions.
