***********

The battle at Xiaocaohu seemed to be even more intense than Chen Yuan and the others had originally expected. This is mainly due to the fact that Chen Yuan did not take into account the dust from the Gobi Desert and did not arrange it in advance. As a result, a large number of zombies rushed to their city walls with the help of the cover of dust. Enough ordinary zombies stacked Arhats seemed to be desperately trying to climb the walls of the Self-Salvation Army, and the reinforced species also brought a great threat to the walls and troops of the Self-Rescue Army.

And just when the battle was in full swing on the battlefield.

A scout in charge of observing the situation on the battlefield suddenly reported to Chen Yuan: "Fort Chief, zombie siege equipment has been found near the wall of the opposite mining area!" There are about 10 of them, they are loading stones, and ladders have been found in the zombie hordes! ”

"Got it!"

Chen Yuan frowned, the battle has been fought until now, and suddenly the siege equipment of the wisdom corpse has appeared, which has to be said to be a relatively big blow to the morale of the self-help army.

He immediately contacted the mortar company behind them.

"Lu Yu, your side will immediately split half of the mortars to shell the wall of the saltpeter mine!"

"Understood!"

It's just that Lu Yu and they are still a little slower than the zombies. When Chen Yuan and the others heard the sound of "whirring" cannonballs breaking through the air overhead, the trebuchet on the saltpeter mine had already started.

More than a dozen huge stones were smashed from far and near towards the city wall of the Self-Salvation Army at a very fast speed.

"Boom Boom"

"Knock Knock"

The cannonballs and boulders hit the ground almost simultaneously. The first test shot was not good, and everyone's hit rate was not good.

There were more than a dozen boulders on the zombie side, and only one fell on the wall of the self-rescue army. A large number of their own zombie soldiers were stoned and turned into meatloaf.

The self-salvation army suffered seven or eight casualties, but a section of the city wall several meters wide was smashed! The earth and stones inside the walls collapsed down the smashed outer walls, and soon a ramp was formed. A large number of zombies saw the opportunity and began to swarm this way.

"Quick! Bring the heavy machine gun mount over, aim at the gap and hit me hard, you must not let the zombies rush up! A platoon commander shouted at the soldiers next to him, ignoring his own stone-throwing foot and shooting his assault rifle under the ramp of the gap in the wall.

Soon, the surrounding fighters also arrived, and two heavy machine guns were immediately erected.

"All ......"

Without hesitation, the warriors shot at the zombies rushing up the slope.

On the other side, on the fence of the saltpeter mining area, two trebuchets were blown up by shells from the Self-Salvation Army.

But this is not enough, the remaining trebuchets on the zombie side have already begun to reload again, and they are not slow.

Chen Yuan immediately contacted Lu Yu again to calibrate the artillery for him.

He shouted: "100 meters to the left of the landing point of your shells, 20 meters forward!" ”

"Understood!"

Soon after, the sound of "whirring" shells bursting through the air again was heard over the Self-Salvation Army.

"Boom ......" this time before the zombie's trebuchet fired, the shells arrived first. The violent explosion blew up 6 zombie trebuchets again.

However, by the time the mortar company launched its third shelling, the remaining trebuchets of the zombies had already thrown stones again.

This time, thanks to calibration, their attacks were much more accurate than they had been at the beginning, with 5 throwing stones and 2 hitting the walls. Again caused casualties among more than a dozen fighters of the Self-Salvation Army, and the collapse of two sections of the city wall. But their trebuchets were all destroyed in the shelling of the Self-Salvation Army.

At the same time, the zombies carrying the ladder had also rushed to the front of the city wall, and there were quite a few of them. With the help of the ladder, the zombies' siege will inevitably go much smoother. This is a great threat.

So Chen Yuan immediately ordered the mortar company to turn the muzzle and shell the open space 50 meters in front of the city wall.

More than 20 shells whistled in, and huge explosions rang out one after another.

Due to the proximity to the city wall, there are many zombies concentrated, so the effect of the artillery bombardment is very good, with the explosion of the shells, many zombies were blown away, and of course, many ladders were destroyed. Suddenly, the pressure on the defenses on the city walls was greatly reduced.

And it didn't take long for the zombies to see that they couldn't attack the city wall for a long time, so they took the initiative to retreat.

"Stop attacking!"

The zombie hordes retreated into the dust and disappeared. Chen Yuan then ordered the attack to be stopped, and it was not visible, and shooting indiscriminately was just a waste of bullets.

So with the help of the maintenance of this piece of dust, the zombies were safely withdrawn to the mining area.

At this time, the zombies who were in charge of chasing Xiao Tengcan were still being entangled by Xiao Tengcan. Xiao Tengcan and the others took advantage of their speed, and after quickly eliminating more than half of the 400 ordinary zombies who were responsible for blocking them, they rushed straight to the retreating 1,000 zombies with the armored vehicle troops. They were entangled in death. As a result, they could not rush back in time to support the attacking troops in the front, so that the frontal troops were insufficient and had to withdraw to the saltpeter mines.

At this time, there were less than 1,300 zombies that withdrew to the saltpeter mine, and only 1,000 zombies who were bound by Xiao Tengcan and them finally escaped back to the saltpeter mine.

So far, the Self-Salvation Army has eliminated 1,700 zombies in the first battle.

And its own casualties were 11 dead, 27 seriously wounded, and 92 lightly wounded. In addition, 11 soldiers were infected by the fortified virus, and after the war, they were rushed to the rear train for semi-corpse treatment.

After this period of time, medical and virus experts on both sides of the Iron Castle and Shenwu City have jointly researched, although the treatment potion for the enhanced zombie virus has not yet been successfully developed. However, the success rate of semi-cadaver treatment for patients infected with the enhanced virus has increased to 7 layers.

On the city wall, Zhang Zeshan asked, "Fort Chief, how are we going to fight next?" The situation seems a bit unexpected. Because of the cover of dust, we didn't have all the zombies that could rush out, and the situation on Lao Xiao's side was also reported, and there should be about 2,100 zombies in the saltpeter mine now. ”

Jiang Wenli frowned and said, "And this time our combat attrition is also very large, reaching nearly 17%. Those who are lightly wounded will not be able to regain their full combat strength until at least tomorrow, and the seriously injured part will take at least two days, and the other part will take at least three days! She scolded angrily: "Bastard, the old lady's troops have never suffered such a big casualty again!" ”

Hearing the casualty reports summarized by various units, Chen Yuan also had a solemn expression. He said: "This is a defeat in the operation, and it is entirely due to our lack of experience in fighting on the Gobi Desert and our failure to take measures to reduce dust in advance." At the same time, it can be seen that we have been too proud and complacent during this time. No one notices such an obvious loophole. Such a lesson is worth pondering! ”

Everyone also bowed their heads one after another, and before the war, all of them, including Zhang Zeshan and Jiang Wenli, were disdainful of the 4,000 zombies in the saltpeter mine, and always felt that they could easily annihilate the zombie group. But they didn't want to, with the city wall defense, they almost lost!
