Those earth dragons covered in red, constantly wailing and rolling on the ground.

And the places on their bodies that were sprayed by the 'venom' were all white smoke without exception, and then huge water cannons quickly grew.

At this moment, the whole team, seeing such a terrifying picture, fell silent.

Everyone looked at Yang Yinuan's eyes and couldn't help but be full of awe!

The lord of the castle is really a god descending from the heavens!

Not only can you play with fire, but you can also play with drugs!

One of the dragon's means of attack is to spray venom, and soldiers have been hit by it before.

But now it seems that their venom is completely pediatric compared to the venom brought by our city lord!

And Yang Yinuan, at this time, he also deliberately held the shelf and put up POSE.

The soldiers looked at him in a strange way, how could he not know what these people were thinking?

Since they are willing to think like that, they must set up a good persona.

Where would these guys know that what they let those people spray is actually a high concentration of hydrochloric acid......

The chlorine gas has been figured out, is this hydrochloric acid still far away?

Since the last time he helped Gao Xin conquer the Iron City, Yang Yinuan came back and began to research chemical weapons.

What's more, this acid liquid is also very beneficial to the industrial development of Qianshan City.

It's a pity that with his technology, he can still make a lot of hydrochloric acid.

It is to mix the toilet cleaner and 84 disinfectant together, and the chlorine gas produced is added to a water tank, and then heated and pressurized, constantly tumbling and stirring.

Chloride ions are dissolved in water and then purified to obtain hydrochloric acid.

Yang Yuanqing prepared a lot earlier, and this time he brought some.

Originally, it was intended to be used as a self-defense weapon, but I didn't expect it to be used in this breakthrough.

This fierce earth dragon, which he had studied before, was a mutated earthworm.

But after this thing mutated, it was quite terrifying.

Able to drill underground, and his size is huge, it is very difficult for the soldiers to use physical attacks to deal with him.

Although it didn't have thick armor, its skin was covered in a kind of slime.

Using a cold weapon like a knife and gun, it is still very difficult to break its protection.

And this thing is huge, if the fighters are allowed to fight head-on, it will definitely lose a lot.

So he put hydrochloric acid on this guy.

To put it mildly, this special large water gun is specially prepared for these earth dragons.

Sure enough, these menacing earth dragons suffered a big loss in front of his two large water guns.

It was the ghost crying wolf who was 'snorted' by hydrochloric acid, and he didn't have time to get close to the team and cause trouble for them.

I was already persuaded to quit by hydrochloric acid......

The earth dragons rolled on the ground in pain, and at this moment two other tanks and carriages also came to the front of the battle.

Take advantage of your illness and ask for your life, this is Yang Yinuan's purpose.

Four catapults fired a salvo at the rolling dragons.

Suddenly, the place where the earth dragon appeared turned into a sea of fire, and this was not enough, they also fired another round of covering shots towards the ground in front of them.

This round of shooting is not a blind shot, but also targeted.

Before, Yang Yinuan sprinkled out more than a hundred nights without collecting them, and some of them went far away without collecting them at night.

And in the process of going forward, they also kept using spears all the way to pierce the ground to test whether there were any sand thieves underground.

And where they walked, if they felt that there was a hole in the ground, there was a risk of hiding sand thieves.

Then they will mark this place, and then these marked places will be covered by a round of fire from the tanks.

Sure enough, this round of fire bombs went down.

Suddenly there was a roll under the seemingly flat sand and gravel ground.

The originally calm sandy land suddenly tumbled violently.

Where there is land, you can see a ridge suddenly appear, and then flee all the way into the distance.

In other places, a burning man with a whole body on fire will suddenly come out.

The burning man yelled and scurried around, and after a few steps he fell to the ground......

The entire brigade couldn't help but be awe-struck when they saw such a picture.

Looking at Yang Yinuan's eyes, he was full of reverence!

The lord of the city is really like a god!

It turned out that before leaving the city, he had already expected that the enemy might be ambushed from this, and even the method of breaking the enemy had already been thought of.

The loss is to follow this adult, if this is to follow others, then everyone may not have many deaths!

Soon the path was cleared, and the sound of horses' hooves sounded behind him.

Yang Yinuan looked back and saw that it was the angry cavalry of the Wanzi Army, who had bypassed the burning city and pursued them.

"All pay attention, let's go full speed ahead, let's go!"

He waved his right hand forward, and the team, which had been stagnant, immediately moved slowly again.

And the speed of marching ahead is getting faster and faster, and everyone knows that if they are caught up by the cavalry of the 10,000-character army, it will definitely not be good.

The obstacles and ambushes in front of us have been swept away, and now everyone can finally beat their horses and gallop with confidence......

The brigade Zou Ran speeded up, and the benefits of the whole army with horses were reflected at this time.

And most of these soldiers, even the soldiers of the Iron Army, were from the North.

Since childhood, he has learned to ride horses, so he is skilled in equestrianism, and in the case of one person and two horses, the speed of the whole army is very fast.

Even the dozen or so carriages are running fast at this moment.

In front of each carriage were three horse-drawn carriages, which in turn were heavy carriages produced in Thousand Mountain City.

The steel keel, plus the steel wheels, and rubber tires, these modern equipment are added to ensure the sturdiness of this car.

On the Gobi Desert, although there are no aquatic plants, the benefits are also very obvious.

It is endless, the road is flat, and it is very suitable for cavalry to run all the way.

As soon as the speed of the Qianshan Army was raised, it was not so easy for the pursuers behind to catch up with them.

After all, there is a distance of several kilometers between the two sides.

What's more, the Qianshan Army will not just blindly bury its head and run away.

Along the way, Yang Yinuan will also command the soldiers to divide into several groups all the way and go back to harass the pursuers behind.

Slow down their pursuit, after all, they have a technological advantage at the weapon level.

For example, the range of their pulley compound bow is tens of meters farther than that of the enemy.

In addition, they run in front and the enemy chases behind, so as long as they keep shooting back the horse arrows, the enemy's speed will not be able to get up.

In this way, five or six squads, harassing in the back in turn, can greatly slow down the enemy's pursuit.

What's more, the horse they sat on was the best hippopotamus in the Hinda grassland.

This horse is fast, has good endurance, and is able to participate in combat for hours on end without eating or drinking.

And those war horses of the 10,000-character army are not good......
