Yang Yinuan's brows were twisted into a Sichuan character.

Previously, when he and Yanzhou Chuyuncheng, as well as Li Gui of Nanyunguo, went to Qingshan City with men all the way to explore the market.

He had also communicated with these two noble sons in the past.

At that time, he was knocking on the side in many ways, wanting to learn more about the world of Falken from the mouths of these two sons.

After all, these two are both children of a family, not to mention well-informed, and they have also received formal education since childhood.

The perception of this world is definitely much stronger than that of ordinary people.

And in the process of communicating with these two sons, he also learned about the composition of the Aurora Continent.

The current Aurora continent is mainly divided by the north and south sides, along the river.

A large river, the Puhua River, divides the Aurora continent into two halves, north and south.

The south is now dominated by the Nanyun Kingdom, while the north is dominated by the Sixteen Kingdoms of Yanyun.

And in the south of the Puhua River, although Nanyun Country is a dominant country, it is not a situation where they dominate the world.

In the southeast and southwest corners, there are many smaller states and city-states.

And in the mountainous area in the southwest, there are many barbarians in Li Gui's mouth.

In his words, these barbarians lived in those 100,000 mountains, and they were all born mountain warriors.

Able to open and close between the mountains, as if walking on the ground.

Every year, Nagumo would recruit some soldiers from those mountains to build their mountain legions.

And today, after seeing these dwarfs climbing the wall, Yang Yinuan suddenly felt a shock.

Could it be that these are the rattan armor soldiers that Li Gui talked about with him?

But looking at the equipment of these people, it doesn't look like it!

Because Li Gui told him that in the army of their Nanyun Kingdom, there is indeed such a vine armor soldier.

However, those rattan armor soldiers, they have always been supported by good wine and food.

And these people in front of them, not to mention that they are yellow and thin, but it can also be seen that they are all men who work hard for life.

Many people's hands are covered with calluses, and even this northern border is almost winter, so cold.

But these people were still wearing thin cloth clothes and straw sandals.

If it was a rattan armor soldier of Nanyun Kingdom, it would definitely not be so shabby.

Since it is not the regular reading of Nanyun Kingdom, then it must be someone with a heart, specifically targeting their tall city walls.

Then they sent people to the mountains in the southwest to recruit these people and let them take the lead......

Good guys, who the hell is this?

In order to target his Thousand Mountain City, is it really painstaking?

Just when Yang Yinuan was wondering what the origin of these people was.

Suddenly, there was a whistle of varying lengths from the arrow tower in front of them.

"Enemy attack, enemy attack, everyone is ready ......"

"Everyone is ready to meet the enemy!"

The officers apparently found something, and then began to give orders loudly.

In the hidden cave behind the city wall, a large number of soldiers soon came out.

These soldiers, one by one, dressed neatly and carrying the weapons in their hands, went straight to their battle positions.

At this moment, Yang Yinuan threw the rattan helmet in his hand to the ground, and then waved his hand at several soldiers.

"Hurry up and get rid of these corpses."

Then he turned and went straight to the head of the city in front of him.

The renovated city wall of the Thousand Hills Fortress is twelve high.

At the original city gate, two city walls extend forward from both sides, which are more than ten meters, and finally close in front.

A huge protrusion was formed, an enveloping shape, so that an urn city was formed between the new gate and the old gate.

And the part that pops out plays the role of a fortress without dead angle defense.

In this way, even if the enemy bypasses the salient and attacks the city walls, the soldiers can also attack the enemy's flanks and behind the walls of the urn city.

Such a seemingly simple design greatly enhances the protective power of the city wall.

At this moment, Yang Yinuan took a few steps to the fortress in the southeast corner of the city wall of the protrusion, and he climbed to the highest place.

Holding a telephoto to look at it from a distance, there was a flare in the distance, slowly falling from the sky.

Underneath the flares, countless black shadows could be seen slowly emerging from a forest in front of them.

Five miles to the front of the Thousand Hills Fortress is a large open field.

It used to be a dense forest, but with the construction of Qianshan New Town, the trees here were quickly cut down.

Originally, it was suggested that this area should be cultivated with grain and developed into fertile land.

But this proposal was rejected by Yang Yinuan, and it was in the consideration of urban security.

He felt that it was just so empty that it would give the defenders on the walls a very good view.

Moreover, displaced people from other places can also camp here and live for a while.

Check for infectious diseases and recuperate your body at the same time.

After passing all aspects, they will be allowed to pass through the Thousand Hills Fortress and go to the Thousand Hills New Town behind.

And now this open land has become a gathering place for those enemy troops.

The refugee camp in the open field has long been empty.

Those black shadows, after burrowing out of the old forest opposite, all walked slowly to this flat land.

They did not rush to attack the Thousand Hills Fortress, but began to form a neat formation there.

Soon from the woods behind, tall catapults were pushed out.

When he saw these catapults, Yang Yinuan finally understood why these people were not in a hurry to attack.

It turns out that they are waiting for such a big killer!

In the past, on the Aurora Continent, he hadn't seen anyone with such a catapult as a big killing weapon.

It is no exaggeration to say that before the birth of gunpowder weapons, this thing was definitely the most powerful weapon that could be used to storm the city.

In the ancient history of Blue Star, many famous offensive and defensive battles were ultimately decided by this thing.

And this time when he was on the western expedition, he had seen the Manyin coalition army and used such weapons.

Could it be that this thing made its way to the North so quickly?

Soon, those catapults had been pushed to a place only a few hundred meters away from the walls of the Thousand Mountains Fortress.

Then the gunners began to operate decently.

A few people began to pull the swing arm, and once the slot was in place, they put a watermelon-sized stone bullet into the net pocket.

Some of them use oil bombs covered in grease, after igniting the oil.

The shooter picks up the sledgehammer and smashes the tenon.

The counterweight at the other end of the swing arm is quickly pressed down, driving the swing arm, and the swing arm is waved to throw the stone projectile in the net pocket.

The principle is simple, but the power is not small.

Stone projectiles the size of watermelons whizzed towards the walls of the Thousand Hills Fortress.

Hua Budu, who was standing beside Yang Yinuan, was already breathing rapidly at this moment.

This is the first time they have been attacked by an enemy's ranged weapon......
