On the side of the Iron Castle, the human forces did not fight the zombies. Instead, after luring the main force of the zombies out of the ground, he immediately withdrew to the Iron Castle "without integrity".

This immediately made the corpse king angry.

Hell, this is a complete waste of its time and expression!

But in the face of the human side, the city wall that is dozens of meters high, and the corpse king, who has less than 900,000 troops left, can't really make up his mind to fight directly.

So he could only control the zombies' deliberate retreat to the underground to continue to work.

And be sure that the human forces will not send troops next time as long as they do not approach their positions. The human side did this in order to slow down its underground construction.

But it's not as simple as the zombies think.

This operation on the side of the Steel Castle, in addition to interfering with the zombies' actions underground, is actually to attract the attention of the Corpse King.

Because at the time when they were at war with the main forces of the Corpse King.

More than ten kilometers away from the entire zombie encirclement, 8 transport planes of the Steel Fort have already begun to airdrop their paratroopers from the Salvation Army in different places.

"Class 1 is complete."

"Class 2 is complete."

"3 classes ......"

In this operation, the troops of the paratrooper regiment will take the platoon as a unit, taking advantage of the convenience of small units to maneuver and hide, and divide into ten different directions, as if they were blooming everywhere, and launch an all-round surprise attack and harassment of the 30-kilometer-long zombie position.

Moreover, the command headquarters did not give a clear mission objective for this operation, and all units could carry out independent or joint combat operations according to their own actual conditions. Tactics are flexible.

Therefore, after the platoon parachuted down from the air, they all began to gather their troops one after another, and quickly launched their actions.

Some of them specifically targeted the scout squads of zombies scattered behind the position.

In order to cope with the surprise attack of the tank units of the Self-Salvation Army, the zombie army scattered a large number of scout squads within 10 kilometers behind their positions.

These scout squads usually consist of a few or a dozen zombies, no more than twenty.

Exactly an excellent target for the start of the paratrooper platoon.

Although due to the nature of zombies, as long as the two sides start fighting, the corpse king will immediately notice it.

And quickly mobilized surrounding troops to rush to the scene to support, wanting to eliminate these troops of the self-help army.

However, the troops of the Self-Rescue Army move quickly, they usually use ambushes, when the zombie reconnaissance team passes by, they suddenly attack, end the battle within a minute or two, and quickly evacuate.

No matter how fast the Corpse King's pursuing troops were, they couldn't catch up at all, so they could only run around the battlefield and get dazed.

Moreover, these paratrooper platoons of the Self-Rescue Army will echo each other from time to time.

If it is found that the zombie force chasing them is not large.

The paratrooper platoons of the self-rescue army around them will quickly gather like sparrows, and with superior forces, they will suddenly hit the zombie troops chasing them behind with a return gun.

You can stun the zombies in an instant! In just a few hours, more than 20,000 zombies were destroyed.

What's the situation, isn't it just a small force?

The Corpse King didn't understand.

It was only possible to immediately mobilize a larger force from the side of the position to pursue it.

But these units of the Self-Salvation Army will quickly disperse like sparrows, disappearing into the surrounding woods and villages.

And because the zombies gathered the limited scout troops in this area and organized the pursuit troops, a large gap area appeared in the rear of the entire zombie position.

Some of the Self-Rescue Army units were able to break through to the edge of the zombie position.

And once again use the flamethrower to deal a huge blow to the zombie troops underground.

The Corpse King was immediately completely furious.

And at this time, the rear of the entire zombie position has been disturbed by these small groups of self-help troops, and it has been a mess.

It seems that there are wars going on everywhere, massive human forces everywhere.

As a last resort, the Corpse King could only continue to urgently dispatch more troops from the position to the rear to support.

So the paratroop unit of the Self-Rescue Army, which only has a size of 6,000 people, mobilized a zombie force with a scale of more than 150,000 and accompanied them to run around behind.

And a total of more than 30,000 zombies have been eliminated.

It also greatly affected the zombie underground project, and the progress slowed down a lot.

*********

On November 12th, under the attack of human forces in many ways, the tunnel of the zombies finally dug near the underground of the human castle.

This was two days later than expected.

Moreover, the actions of the zombies were immediately discovered by the human side.

Liu Jinlong quickly reported the situation to Chen Yuan: "Fort Chief, the zombies are indeed digging tunnels, and we have heard the sound of zombies digging tunnels in multiple directions of several underground shelters. According to the analysis, the nearest is already less than 100 meters away from us! ”

Chen Yuan nodded and said: "Those who should come still want to come, immediately arrange for the evacuation of residents in the relevant areas to transfer, and inform all troops to prepare for battle." At the same time, he ordered the personnel in charge of listening to continue to listen, and he must not miss any place where the zombies are digging tunnels. ”

Liu Jinlong nodded and said, "Got it!" I'll arrange it right away. ”

Qin Cheng said with a smile: "It's November 12th now, and even the temperature during the day has dropped below zero." It's time to let the zombies come, or the corpse king will be scared back by the temperature here. We'll also have one less chance to continue cutting down on the zombies' living power. ”

"yes!" Wang Luzhou said: "It's almost time for the paratroopers to stop harassing the rear of the zombies." In addition, I suggest that when the zombies first start attacking, we can put some water properly. Because the speed of zombie excavation tunnels will definitely be different, if the zombies are driven out at the beginning, the zombies may also directly give up the excavation of other tunnels. ”

Chen Yuan smiled and nodded, "Okay!" ”

So the paratroopers of the Self-Rescue Army stopped attacking the rear of the zombies.

And the underground excavation of zombies has suddenly accelerated a lot.

At around 2 a.m. that night, the first tunnel, dug from a few kilometers away, finally reached the Underground Vault 3 of the Steel Castle.

It hadn't been reinforced yet, and the walls were just under 30 centimeters thick, with the force of one of the earth-based mutants among the zombies.

The reinforced concrete walls were suddenly lifted open as if they were papier-mâché.

A large number of zombies instantly poured into the underground shelter of the Iron Castle.

At the same time, near the walls of the underground shelter that had been broken by the zombies, the human forces had already prepared.

And so the great war began in an instant.
