Seeing that all the Qianshan troops had gradually gathered at the bridgehead south of Yishui Bridge.

On the other side of them was an army of greenskins who had formed a state of encirclement, and at this moment, after the last mobilization of the battlefield, these guys began to roar and surround the remnants of their bridgehead.

But just when they were still fifty or sixty meters away from the remnants of these Thousand Mountain Army, suddenly one after another fire oil bombs pierced the sky like a pandemic.

Since Yang Yinuan brought a new method of incendiary blending, this kind of fire oil bomb has become the most effective means of killing the enemy on the battlefield of the Qianshan Army.

"Bang ......"

One by one, the fire oil bombs smashed into the battle formation of the greenskins like meteors, catching them off guard.

A large area was smashed on the spot, and dozens of people turned into torches on the spot.

This sudden blow can stunned these green-skinned people who were still fierce just now.

What's going on?

The width of this Yi River is four or five hundred meters, how can the enemy on the other side of the river have a weapon that can project so far?

You must know that in these years, the farthest attack distance of ordinary long-range throwing weapons is just more than 300 meters.

It had to be the kind of longbow that was nearly two meters long, and the maximum attack distance of the arrows was fired.

But that was for the ordinary army, and for the Qianshan army, especially after Yang Yinuan brought them a lot of modern tools and instruments.

This is a long-range strike weapon that has made the Qianshan Army have a sharp increase in variety.

For example, Yang Yinuan brought a large number of springs, and after the transformation, it became the most powerful catapult cannon of the Qianshan Army.

In fact, it is a large slingshot with a sliding nest, and the firing distance can reach up to 500 meters.

And their steam catapult cannon, which uses a steam engine to pull a net woven with a powerful wire rope, and then shoots a swarm of giant arrows out.

The longest range can also reach 400 meters......

Even their ordinary crossbowmen were able to extend their range to three hundred and fifty meters with a pulley compound bow.

This is more than double the range of other archers of the era who used recurve bows......

The army of greenskins on the opposite side obviously didn't expect them to have weapons with such a long range, so they suffered a big loss this time.

The fire oil bombs smashed down like raindrops, forming a wall of fire that could not be broken through at all a hundred meters in front of the battle formation of the Qianshan New Army.

At this time, the new army, which had already recovered from its senses, quickly organized a large number of archers, using their characteristic pulley compound bows, and began to launch a ferocious revenge on the enemy on the other side of the wall of fire.

The thick layer of leather armor on the enemy's body was able to block their swords and guns.

But at such a close distance, they could not stop their powerful bows and arrows.

After a rain of arrows, another seventy or eighty people were shot over.

The greenskins were in a state of confusion, and at that moment they suddenly felt a sudden darkness overhead their heads in the sky.

When I looked up, I saw that above their heads, a dense rain of arrows covering the sky and the sun was shooting down from above their heads.

The green-skinned man who had just stood up to boost his morale was screaming even more at this time.

Then many greenskins raised their shields in their hands, but unfortunately their shields encountered such a powerful rain of arrows, and the protection suddenly became dispensable.

Many green-skinned people were nailed to the ground on the spot.

Rows of volleys of fire and oil bombs and arrows rained down in the air, as if it were an iron curtain, firmly covering the Qianshan New Army within the iron curtain......

The leader of the greenskins, who was very clever at this moment, rolled twice on the ground, and then roared a few words loudly.

This group of fierce guys immediately retreated in all directions like a tide.

After a while, he retreated into the surrounding green jungle and walked cleanly......

This scene really stunned Yang Yinuan.

It is really rare to be so decisive and never entangle the leader who immediately withdraws his troops when he finds that the momentum is not right.

This group of greenskins really made him realize what it means to come and go like the wind......

The enemy's retreat was so decisive that not only did he greatly surprise him, but also the new army on the opposite side.

So much so that after the enemy had retreated for a quarter of an hour, they dared to slowly walk out of their positions.

Start exploring ahead of the curve......

After a few moments, they were relieved to confirm that the enemy had really retreated.

At this time, the engineer battalion also cut down a lot of big trees from the dense forest next to the river embankment.

With their own chainsaws and axes, they quickly split the wood into slabs and erected them where the bridge had been broken.

Even if a simple bridge was built, Yang Yinuan began to quickly organize a large army to cross the river.

Because this is only a temporary bridge, everyone is very cautious.

Although the number of passes at a time is small, the speed is still very fast.

When it was getting dark, Yang Yinuan finally led the whole army across the river.

However, after crossing the river, he did not give the order to rest, but immediately ordered the whole army to march.

Because the former army that was sent out before has not heard back yet.

At Qiaotou, he had already lost 1,000 recruits, and he didn't want those 2,000 veterans to be dumplings.

Sure enough, not far ahead, traces of battle were seen on the ground.

There were a lot of corpses of the Thousand Mountains Army and the Greenskins on the ground, as well as many broken weapons.

It can be seen that the battle between them is very tragic, and seeing this scene, everyone understands why the front army has not withdrawn reinforcements just now.

It's not that they don't want to, it's that they can't......

The further we went, the more intense the battle became, and more and more corpses of both sides began to appear on the ground.

Yang Yinuan hurriedly asked the soldiers to clean up the battlefield and find out the wounded who were still alive as soon as possible.

Soon, many wounded were collected.

One or two others who were not seriously injured were brought to Yang Yinuan, and Yang Yinuan began to ask what had happened to them.

According to the confessions of these wounded, it was exactly what he guessed.

It turned out that not long after the former army walked out, they were also ambushed by these greenskins.

And the greenskins besieging them are more numerous and more ferocious in combat.

They wanted to retreat back and join the main force, but they were divided and surrounded by the enemy.

Moreover, the enemy also had cavalry, and what frightened them the most was that there were still many heavy infantry in the enemy's battle array.

According to these wounded soldiers, these heavy infantry are like iron towers, and their combat effectiveness is amazing, and they are quite terrifying anyway.

Their generals, seeing that the back road was cut off and that they were constantly being compressed by the enemy, could only fight and walk.

Before they knew it, they were squeezed to the south, and according to the wounded soldiers, they were supposed to hold on to a high dirt slope to the south.

Hearing this, Yang Yinuan immediately asked people to speed up the march.

At the same time, he also prayed that the soldiers would hold on......
