The second defensive position of Yangcheng is the main city wall of Yangcheng!

The main city of Yangcheng was built above the location of the super-large secret base No. 97531, which is actually a bit like the new city of Oil City, which was built on a hill. It is also the structure of two walls.

It's just that the hills here are steeper.

It is relatively good for defense, but the colony is not so comfortable.

In fact, this extra-large secret base at their feet is enough to accommodate hundreds of thousands of people. But people couldn't stay underground all the time, so a new city was built on top of it.

And now the ordinary residents here have retreated to a secret base in the heart of the mountain, quietly waiting for the arrival of the big war.

********

At the same time, the main force of the zombie group has also arrived 15 kilometers away from Yangcheng.

The artillery group of Yangcheng began to attack again.

With 800 guns firing at full range, a single salvo can cover a large area. Those who were not physically present could hardly appreciate the power and magnificence of the firepower.

But as before, the human shelling had just begun, and the main force of the zombie horde immediately began to dodge the shells.

Lie down, hide behind slopes, duck into ditches, duck into craters, and even defend with dead zombie corpses. The zombies do everything they can, but they can really reduce the casualties to a great extent.

It's just that this time, the large props such as siege equipment carried by their main force were not easy to hide, but they were destroyed a lot by Yangcheng's artillery fire.

In the end, the shelling was carried out by the Yangcheng side for about fifteen rounds before stopping.

Blew up almost everything that could be fried.

But after the shelling was carried out, the zombies were basically hiding very tightly. No matter how much it is bombed, it can't blow up any birds, it is a complete waste of shells, and the Yangcheng side suspended the shelling.

But wait until all the zombies get up and move on. The shelling of Yangcheng began again.

But this time, the artillery troops on the Yangcheng side only fired two salvos, and after the zombies hid tightly, the artillery units of Yangcheng stopped fighting.

It wasn't until the zombies hid for a while, found that the shelling had stopped, and continued to move forward, that the artillery attacked again.

In this way, the artillery units in Yangcheng stopped fighting, and the zombies were forced to stop and go, and their speed was greatly reduced.

This is actually a strategy that Chen Yuan came up with.

Because according to the zombies' schedule, their main force set off at 9 o'clock in the morning, with a large number of siege equipment, and arrived at the north of Yangcheng at about 9 o'clock in the evening, which happened to be dark at this time.

Fighting, of course, is not good for humanity.

Therefore, Chen Yuan hopes that through this method, he will try to delay the arrival of the main force of the zombie army. It's best to delay until the next morning, or not until the middle of the night, at least after a few hours, it's dawn. They don't have to fight zombies all night.

Now Chen Yuan's strategy has really worked.

The previous army of 900,000 zombies carried a large number of heavy siege equipment to advance, and it only took about 10 minutes to walk one kilometer.

But now that they are interfered with by Yangcheng's artillery, they keep lying down, getting up, lying down, getting up, and they can't get up at all. It takes more than half an hour, or even more than an hour, to walk a kilometer!

Wang Luzhou, as the commander of the Yangcheng side this time, laughed happily: "Haha! Chen Yuan, this plan of yours is really amazing. The current speed of the main force of the zombie group is really not good! If you really want to walk down at this speed, the 13-kilometer journey will take more than 12 hours to walk! It won't be until the next morning! ”

Qin Cheng also said: "Yes, it is much better to fight during the day than at night!" Your trick can help us reduce a lot of unnecessary casualties! ”

Chen Yuan smiled and said, "Actually, the zombie group can also choose to let the troops who don't bring baggage go first. ”

He said: "At this temperature, the speed of zombies is completely unaffected. At a speed of nearly 55 kilometers per hour, it takes less than 20 minutes to run more than ten kilometers. And at such a fast speed, it will be difficult for our artillery to hit accurately. ”

"However, this will cause their baggage, which was originally hidden in the large army, to be completely exposed to our sight, so we can mainly attack their baggage troops. Once all of their siege engines are destroyed, their siege operations will be greatly affected. Just by piling up the city wall with the corpses of zombies, it will cost a lot! ”

Everyone nodded, and Wang Luzhou said, "I will let the reconnaissance troops in front pay attention." ”

**********

At this time, the Corpse King also seemed to be so careful, so he continued to control the main force and slowly advanced under the cover of the baggage.

Of course, this is actually quite expensive for the human troops.

But what does it matter, these shells were meant to be thrown into the zombie horde.

Now you can keep destroying the zombies, and you can delay their time, so why not.

So this road is really miserable for zombies!

It wasn't until later that the Corpse King seemed to finally realize that it couldn't go on like this, and it was obviously a delaying tactic on the human side.

So he gritted his teeth and began to separate the main force from the baggage force, so that the main force could rush through the shelling area of the human army at the fastest speed and join the vanguard force in front.

But at this time, it was already past 12 o'clock in the middle of the night.

And sure enough, as soon as the main force of the zombie group broke away, their baggage troops fell behind and became very conspicuous. And immediately came under attack by the artillery units of the Yangcheng side.

Only at this time, the earth was completely shrouded in darkness with only a faint moonlight. The darkness of the night also provided some cover for their baggage troops, making Yangcheng's artillery guidance less accurate.

It was precisely because of this that the Corpse King made up his mind to separate the main force from the baggage army.

**********

It was around 0:40 a.m. that day. The main force of the zombie group finally arrived outside the northern pass of Yangcheng and joined their vanguard forces. At this time, the main force of zombies was about 800,000. Coupled with the 80,000 zombie vanguard troops here, and the 30,000 zombie baggage troops behind, the total strength is about 910,000.

Previously, Yangcheng's long-range artillery unit had fired 60,000 shells.

In other words, on average, one shell killed 1.5 zombies.

In the face of zombies, this efficiency is already very low.

However, at this time, the Corpse King also fell into a dilemma...... 2k reading web
