The train headed north, and that night, the train didn't stop again. By the time they arrived, all the obstacles on the railroad had been removed, so the train was moving smoothly.

At 7 o'clock the next morning, the train had already passed through Tongcheng. The reason why I didn't reach the Steel Fort after 14 hours of walking is because for the past 14 hours, I drove at night, and although the speed was faster than the previous test, it was only 90 kilometers per hour.

However, by this time it was already getting lighter, so the conductor began to increase the speed of the train back to 180 km/h during the day. Anyway, now there are no other trains on the railway except them, so they can run with all their might.

Six hours later, at 1 p.m., they were back at the Hatta Town train station.

Leaving the troops behind to unload the supplies, Chen Yuan himself took Qin Mengyao and Qin Mengxue back to the Steel Fort first.

The first time she visited the Steel Castle, Qin Mengxue felt very novel, the urban planning here was much better than that of Shenwu City, whether it was a wooden house or a newly built house later, it was also very chic, very similar to the towns she had seen when she was a child in Europe. So along the way, I always babble, and kept taking out my mobile phone to take pictures.

Chen Yuan first brought Qin Mengxue to his house. Wu Qingfang had been waiting for them for a long time.

And Qin Mengxue's residence has already been arranged, and during her time in the Iron Castle, she will live with Qin Mengyao first. The house is next door to Chenyuan, and the decoration is very comfortable. A very grand welcome dinner was also arranged in the evening, and all these arrangements made Qin Mengxue feel very happy.

Nine armored personnel carriers and three self-propelled guns were put into training on the day they were returned to the Iron Fort. Soldiers need to familiarize themselves with the condition and performance of the vehicle as soon as possible.

After two days of running-in and familiarization, the battle of Yunxi Town officially began three days later, that is, on the morning of February 1.

At 8 o'clock in the morning, together with the five tanks that were later repaired and sent to the Iron Fort, the 28 tanks of the tank battalion lined up 800 meters outside the north wall of Yunxi Town and opened fire first.

"Bang Bang ......" ad_250_left ();

The strategy and tactics of the Self-Salvation Army are always moving forward in constant summarization. In the past they bombarded the city walls with mortars. But then they gradually discovered that it was most efficient to bombard the walls with tanks' direct-aim artillery.

Most of them used to be ordinary people. The highest military rank is Xu Kai, who was a major before the end of the world, but he was an intelligence officer. The rest is a lieutenant, but a pilot. There was not a single real officer. In this regard, they are much worse than the regular troops.

"Boom, boom, boom......"

Sawdust flew, the first round of tank salvos, and all the shells accurately hit the walls of Yunxi Town.

And due to the powerful penetration of direct-aim artillery. The cannonballs pierced the first plank wall one after another, exploding on the log wall. So this shelling didn't just blow up the first wall of Yunxi Town. Instead, the force of the explosion spread through both walls at the same time, blowing them both apart.

The artillery attack was so dense that the points of explosion were almost connected, so that large sections of the city wall were left unsupported and collapsed in the explosion.

"Oh...... All hits! The fighters cheered.

However, the smoke cleared, and they were taken by surprise. In the two wooden walls, there was an additional half of the unfinished earth and stone wall.

"No, how can there be a third city wall, it's endless!" Wei Chen's voice sounded in the officer channel of the Self-Salvation Army.

Liu Jinlong said: "No wonder the zombies in Yunxi Town have been so strictly guarded in recent days, neither half-corpses nor drones can enter." Turns out they're secretly building a third wall! ”

"The earth and stone walls are useless, I don't believe that the earth and stone walls can withstand cannonballs!" Jiang Wenli shouted angrily.

"That's right, as long as there are no earth-based mutant zombies, even the reinforced concrete city wall is useless." Chen Yuan confidently ordered: "Order the tank troops, continue shooting." ”

"Bang ......"

The second round of attacks of the tank battalion began.

The town of Yunxi on the opposite side shook the ground, and the city wall was dusty again. By the time the smoke cleared, the semi-finished city wall, which was already just over 4 meters high, was only more than 2 meters high.

Chen Yuan immediately ordered the tank battalion to start the third shelling.

This time, the walls are still more than a meter high. But Chen Yuan knew that the effect of the shelling had reached its end.

Because the remaining city wall is more than one meter high, it is actually a pile of earth and stones formed by the rubble of the city wall, and it cannot be regarded as a real city wall. Warriors can easily rush up the slopes.

"Finally blew the walls down." Wei Chen's voice sounded again in the channel.

"What's the use of that, it's not a zombie that hasn't been seen yet." Du Ruhai said bluntly.

Wei Chen couldn't laugh or cry, and replied: "We too, now the zombies are proficient, our snipers have been ambushed outside the four city walls for a morning, but not a single zombie has been seen." As long as we don't launch a full-scale attack, the zombies won't go up to the city walls. ”

"Hehe, this is because we were harassed before!" Chen Yuan said with a smile.

In the past nearly 20 days of harassment, there were about 3,000 zombies on the city wall of Yunxi Town, who were killed by the gunmen of the self-rescue army who were ambushed under the city wall of Yunxi Town, so that the corpse leaders did not dare to arrange zombie archers to defend the city on the city wall. It's no wonder that the corpse leader was forced to rush and risked sending zombies out of the city to ambush the troops of the self-rescue army.

But at this moment, Liu Jinlong suddenly reminded in the officer's channel: "Everyone, pay attention, there are zombies coming out in the north!" ”

Sure enough, everyone immediately saw in their binoculars that in Yunxi Town opposite, some zombies had rushed out over the rubble of the city wall more than 1 meter high.

"Haha, there are really zombies coming out. I just thought that all the ordinary zombies in Yunxi Town were controlled! Zhang Zeshan stared at the group of zombies rushing over on the opposite side, his eyes lit up.

Chen Yuan said: "Of course it's impossible, if there are so many corpses, we don't have to fight." Let everyone calm down, there shouldn't be too many zombies coming out this time, and when you put them in, you will fight again, and strive to annihilate them all at once. ”

"Understood!" The battalion commanders of the six battalions on the frontline position, as well as Wei Chen, Xiao Tengcan, Chen Shusheng and others, replied one after another. This time, except for Chen Yuan, who dispersed the snipers to the west of Yunxi Town, all the other troops were concentrated in the north of Yunxi Town.

"Fire!" About 5 minutes later, the group of zombies that rushed out of Yunxi Town had reached more than 3,500, and their vanguard had reached a position less than 100 meters away from the position of the self-rescue army. Chen Yuan immediately gave the order to open fire.

Six field infantry battalions and one fire support battalion were deployed on the front, and nearly 2,600 fighters were the first to open fire. The unprecedented fierce firepower immediately formed a dense network of fire in front of the zombie group.

The group of zombies in the charge immediately paused as if they were hitting their heads head-on against a solid wall. A large number of zombies were hit by bullets, and some were even hit by more than a dozen bullets at the same time in an instant, and their bodies were immediately beaten into a sieve, and after a burst of blood, they slowly fell.

Immediately afterwards, the 80 guns of the mortar battalion carpet bombarded the zombies at the back of the zombie group. The fierce shelling blew up a large number of zombies into the sky, the smoke dispersed, and there was hardly a single intact zombie in the second half of the entire zombie group.
