**********

Just when the Corpse King decided to step up his attack on the self-rescue army on the mountain, and after paying a lot of price, he finally let his zombie army approach the human position on the mountain step by step.

Unbeknownst to it, the long-range artillery unit of the Self-Rescue Army on the mountain was rapidly withdrawing at this time.

The zombie army has gathered at the foot of Wulian Mountain, which is within the minimum range of long-range artillery, so long-range artillery is no longer useful, of course, it must be withdrawn quickly.

And only the mortar regiment was left as artillery support.

In comparison, mortars are much simpler to retreat than long-range artillery. With the current level of reinforcement of the fighters of the Self-Rescue Army, the artillerymen of the mortar unit can even watch one gun and two boxes of shells run wildly for ten or twenty kilometers as long as one person. Not to mention the special transport vehicles!

In short, without the Corpse King knowing, the human forces on Wulian Mountain were ready to pit it.

But at this time, the battle here on the mountainside continued, and it was fought very fiercely.

The Fire Support Brigade and the 2nd Field Brigade of the Self-Rescue Army are completely in accordance with Chen Yuan's requirements and are doing their best to stop the zombies.

The new weapons didn't need money to fire at the zombies rushing up the hill, and grenades and mortar shells were also constantly falling.

The fierce fire knocked back the charging zombies one after another.

But at the same time, they were also fiercely attacked by zombie archers and various ranged attack zombies.

In the face of dense zombie arrow rain, zombie bombs, flasks, bone crushing bullets and strong acid attacks, even if there are trenches to protect them, many soldiers have died, and there are not a few wounded soldiers!

12,000 against 2 million, it's definitely an unfair war.

But the fighters fought very tenaciously, and they continued to fight even if they were wounded.

Because everyone knows that although they are just bait this time, they can have withdrawn without having to fight so hard. But one day, they still have to really face the zombies, and there may be no way to retreat when the time comes. So it's better to take advantage of the retreat now and come early to explore the bottom of the corpse king's army.

And the zombie army is really powerful!

Under the fierce resistance of the self-rescue army troops with the help of advantageous terrain, although they suffered heavy losses, a large number of zombies would fall with each charge. However, with their absolute superiority in strength, they have always been steadily advancing upward, and they are getting closer and closer to the positions of the human forces.

When the battle here reached the 30th minute, the vanguard of the zombie group had already touched a place less than 50 meters away from the first position of Wulian Mountain.

Zhang Zhen immediately contacted Chen Shusheng and said, "Mr. Chen, the wind is tight? ”

Chen Shusheng looked at the time, and Chen Yuan's requirement for them was to hold on to the first line of defense for a minimum of 15 minutes. They have all held out for more than 30 minutes now, and they can retreat completely.

So Chen Shusheng, as the commander of the war, said to Zhang Zhen: "Withdraw!" Retreat to the second line of defense! Let's fight him again! ”

"Okay!" Zhang Zhen responded. Yes, they have a second line of positions next. Therefore, when withdrawing from the first line of positions, there is no need to report to Chen Yuan. After all, the battlefield is changing rapidly, and everything cannot be reported layer by layer.

As a result, the fire support brigade and the 2nd field infantry brigade of the Self-Salvation Army immediately began to retreat.

But they first called in the artillery support on the top of the hill and used mortars to carry out a covering bombardment of the zombie army in front of them.

Then, while the zombies were lying down and dodging, the officers and soldiers on the self-rescue army position turned around and rushed out of the trench and ran towards the second position on the mountain.

And this is also the last line of defense in this combat operation. Gasoline drums have been placed in many places further up. If you accidentally light it, you're pitting yourself.

Soon, the zombies who were lying down to avoid the human bombardment found out that the human troops had actually escaped.

The Corpse King was very excited, and he actually felt very relieved.

At the same time, he also controlled the zombies to continue to launch a fierce attack on the second line of human beings, and the battle was equally fierce.

Then, after another 30 minutes, the zombie army advanced again to less than 80 meters away from the second line of defense of Wulian Mountain.

At this time, Chen Yuan took the initiative to get in touch with Chen Shusheng and Zhang Zhen, and he said, "Uncle, Zhang Zhen, inform the troops to prepare to retreat." We have almost touched the bottom of the corpse king's army, and the troops on the mountain have almost withdrawn. Then I'll ask the mortar regiment to cover for you one more time, and you'll take the opportunity to retreat up the hill at once. Don't stop a step after entering the Five Lotus City, and immediately descend from the north, understand? ”

"Understood!" Chen Shusheng and Zhang Zhen did not insist, and there was really no need to continue to fight until now. Zombies really can't be stopped. Although the terrain here is good, it is not a real city wall after all.

So a minute later, the mortar regiment of the Self-Salvation Army opened fire again.

The fire support brigade and the field infantry brigade also took the opportunity to break away from their positions again and ran towards Wulian City on the mountain.

At this time, the zombie army immediately began to pursue under artillery fire.

But the zombies' joints are stiff, and climbing mountains is not their strong point, plus with the cover of the self-help army and artillery, they naturally can't catch up.

As for the Flying Corps in the zombie army.

Wei Chen, who remained on the mountain, would provide cover for the people of the two armies.

As a result, the Fire Support Brigade and the 2nd Field Brigade successfully reached the mountain.

After they joined Wei Chen's special operations battalion, the three troops passed through Wulian City without stopping at all. Take the road to the north and leave the mountain.

And the mortar units left one step ahead of them.

So when the zombie army in the south of Wulian Mountain caught up with the mountain, what was in front of them was already an empty city.

The zombie army suddenly stopped advancing under the control of the Corpse King.

At this time, although the troops on the front line smelled a large number of human scents, it was obvious that the humans here had just been withdrawn.

But because of the lesson of Wulian City not long ago, the Corpse King did not rashly send a large number of zombies into Wulian City this time.

Instead, he first sent some flying corpses into Wulian City to check the situation, while the large army waited outside the city.

Through the cameras arranged in Wulian City, Chen Yuan and the others also discovered the situation of the zombie army. Chen Yuan suddenly smiled and said, "Hehe, it seems that the Corpse King has indeed learned smart!" ”

Zhang Zeshan asked, "Castle Chief, zombies won't find out the problem, right?" ”

Chen Yuan said: "We have covered up the places where the gasoline barrels are placed. Zombies should not be easy to spot. But maybe. Don't underestimate the wisdom of the Corpse King. Otherwise, it would have been tricked into it by us just now. ”

"yes!" Liu Jinlong also said with a smile: "But even if it is discovered, it doesn't matter, we have already arranged gasoline barrels above the halfway up the mountain." They didn't notice it before, and even if they ran now, it would be too late! ”

"So what are you waiting for?" Zhang Fatzi said excitedly: "Then hurry up!" Anyway, no one cares about environmental protection now! ”

Chen Yuan said: "Don't worry! Don't you see that there are zombies driving up the mountain under the mountain! Wait for them to fetch more zombies up the mountain, and we'll order them again. You can also bake more zombies! ”

But as he was talking, everyone suddenly saw that the zombies outside Wulian City had moved.

Under the command of the Corpse King, they began to turn around and go down the mountain!

Chen Yuan shrugged his shoulders and said regretfully: "What are you talking about, it seems that the zombies have found a problem." Set fire to ...... immediately"
