On the main position of the zombies, more than 800 artillery corpses were ready to attack. To provide fire support to the zombie infantry attacking in front.

They all hid under cover, sticking their necks, the barrels, out of the ground and pointing in the direction of the Iron Fortress!

Fortunately, in the previous guerrilla warfare, the two mechanized infantry brigades of the Self-Rescue Army had eliminated more than one-third of the zombies' baggage troops (the artillery corpses belonged to the zombies' baggage troops), otherwise the number of artillery corpses might be even more now!

This is also the reason why Chen Yuan said before that the pressure on them will still be a lot in a head-on battle! The base of zombie attacks is too large.

And with the fire of these cannon corpses, more than 800 zombie bombs rose into the air under the cover of darkness and went straight to the direction of the Steel Castle.

These zombie bombs are the size of a volleyball and are difficult to spot in the night sky.

And now these zombie bombs are more powerful than human grenades.

There is a great threat to the forces of the human coalition on the city walls!

"Not good! It's a zombie bomb! Hide! ”

It wasn't until they were very close that the zombie bomb was discovered by the human defenders on the city wall.

The officers gave a reminder, and the fighters took refuge.

And the zombie bombs also fell quickly!

"Boom ......"

Immediately there were explosions near the walls of the Iron Keep.

More than 800 bombs exploded, and the sight was no less than the carpet bombardment of human artillery units! The scene is terrifying!

Thankfully, not all of these bombs are accurate. A significant portion of the zombie bombs landed in front of and behind the walls of the Iron Castle.

Only part of them hit the walls of the Iron Citadel.

There were even fewer that landed on the positions of the human defenders at the top of the city walls.

And there are many human beings on the city wall to protect it. At the moment when the zombie bomb fell, many of the strangers took action.

Ice shields, wind shields, and water shields frequently appear as defense shields, and even lightning and fire abilities directly launch long-range attacks, using lightning and fire dragons to attack zombie bombs that are still in mid-air. So it blocked a lot of zombie bomb attacks.

In the end, it is estimated that there are less than 40 zombie bombs in the human defenders' positions on the city wall.

Moreover, the officers and soldiers were also prepared in advance, so the casualties caused by a round of zombie artillery salvo to the human troops were actually not very large.

Although hundreds of zombie bombs were hit on the walls of the city wall, they did not move. After all, it's only a little more powerful than a grenade, and it can't blow up the city walls. Not to mention the walls that have been strengthened by several earth-based abilities in the Iron Castle.

However, in the steel fort behind the city wall, many houses were slightly damaged by zombie bombs.

Immediately afterward, the human artillery units also began to counterattack, and a large number of mortar shells whistled away. These shells have a high parabolic angle and can be easily sent into zombie bunkers. So even if the artillery corpses were hiding in the trenches at this time, there were still losses.

*********

On the other side, the corpse king controls the mutilated zombies to jump directly into the river to pave the way, which is very efficient.

The zombies had no thoughts, and under the control of the corpse king, they jumped down the river one after the other without hesitation. It's even faster than the human engineering troops can build pontoon bridges.

Although the mortar unit of the Self-Rescue Army is also desperately trying to stop the movement of these zombies with shells, the effect is not obvious.

The people were originally going to use their bodies to fill up the Nenjiang River, and it would be useless for you to blow them up with shells, and the corpses would still remain in the river and become part of the roadbed.

So a road about 20 meters wide and paved with zombie corpses quickly advanced meter after meter in the direction of the Iron Castle.

It is estimated that only the Corpse King has the courage to fill out a path with an army of tens of thousands of zombies.

Of course, a large number of boulders thrown by the zombie catapult troops before fell into the river, which actually provided support for the zombie army to pave the way. Saved a lot of zombie troops. Otherwise, the 500-meter-wide river and the 20-meter-wide road may not be filled with 50,000 zombies.

On the bridge, the zombie troops have advanced to the position of the drawbridge.

The fighting here is fierce, and it can even be described as tragic!

While the zombies continued to shoot arrows at the human defenders on the city wall, they desperately threw the dead zombies, or even those who were not dead, into the river to fill in the road.

Some acid corpses are also trying to target the chains and bearings that hang the suspension bridge, trying to destroy them with strong acid and make the suspension bridge fall.

But the human defenders on the walls are not ornaments. The horizontal distance is only 35 meters, and even if the vertical distance is added, the distance between the two sides will not exceed 60 meters.

At such a close distance, if you can't hit it accurately, it's a problem with your eyes. So with full firepower, most of the zombies who had just rushed forward were killed immediately. Enhancements such as Acid Corps and Flying Corps are the primary targets. There was no time to wreak havoc on the drawbridge of the Steel Fort.

The corpses of the zombies on the bridge have been paved layer after layer, directly pushing up several meters high. Even the zombies who were throwing these corpses down the river to fill the road didn't have time to clean up.

Therefore, the corpse king later simply directly controlled the zombies in front of him to jump into the river to pave a way.

Anyway, stranded on the bridge deck, there is no cover, they are also dead, it is better to pave the way, so that the large army behind can continue to advance.

This accelerated the zombie army to continue to move forward.

(Actually, the human troops on the city wall have been released a little, after all, if you are too strong, it is not easy for the zombies to be scared away.) If the zombies come back next summer, the speed will not be what it is now! ）

Later, Chen Yuan and the others estimated that this night, the zombies estimated that they used at least 70,000 zombie corpses to fill in a road to the city of Steel Castle.

This is a very scary number.

So this night's battle, of course, ended with the defeat of the zombie army!

Because of the deduction of the zombies used to fill the river and pave the road, as well as the zombies killed on the road by the human defenders, there are only a few thousand zombies that can finally rush to the walls of the Steel Castle!

In the face of the 40-meter-high wall of the Steel Castle, these thousands of zombies didn't even have time to build a cloud ladder before they were killed by the human defenders on the city wall. The army of 100,000 zombies arrived here, and it was completely wiped out.

At this time, the time was already 5 o'clock in the morning.

In two hours, the sky would be bright, and the Corpse King would not continue to attack.

And it later discovered that even with the path it paved, the passage to attack the Iron Citadel was still too narrow.

If a formal attack is launched, tens of millions of troops will eventually be blocked at the entrance of this passage and become a live target for human artillery!

So the Corpse King has a new plan at this time!
