The weapons he bought from Liukin last time haven't been used much, so Xiao Feng doesn't plan to replenish them this time.

The last time he left the Otherworld, because he was also worried that the orcs would really catch the dragon, Xiao Feng also made preparations on the side of Riverrun.

But judging from the human resources he currently has at his disposal, it is just enough to arm Riverrun City and build huge towers in Riverrun, while such air defense tower designs have not been completed in other cities.

If there is no worry at all, it is impossible, so Xiao Feng's first stop on this journey to the other world was in Napal Mountain City.

After all, this is the forefront of the human fight against the orcs, with the Napal savannah in front, the canyon in the back, and the gourd gorge and Qukai City in the back.

Further back is the last line of defense of this human tribe, Riverrun, and behind Riverrun is the unsafe Pennivera Prairie.

So this time, Xiao Feng planned to go to Napal Mountain City first to see if the frontline city had been attacked during this time.

But after crossing over, he felt that something was wrong this time, because the sky was full of black smoke, and the air was filled with the smell of burning.

And when he came to the location of the mountain city of Napal in his memory, he was completely stunned by the situation in front of him.

Previously, he had people renovate this mountain city, as an outpost of human beings, although this city is not tall, but it is not a small city, but now this city is in ruins.

There were ruins everywhere, and the ground was covered with char, apparently destroyed by a fire.

He could smell the smell of animal carcasses being roasted from a long distance, and Xiao Feng couldn't help but feel nauseous.

Seeing this situation, he chuckled in his heart, the most fearful thing still happened, it seemed that those orcs had really found the dragon.

And now this mountain town of Napal should be the dragon's masterpiece!

How about the city of Qukai? Is there still there in the gourd gorge?

As soon as he thought of this, Xiao Feng felt like he was being grabbed in his heart.

He quickly took the Ka-50 out of space, boarded the plane and flew directly to the rear.

When he came to the sky above Qukai City, the situation he saw was similar to that of Napal Mountain City, but Qukai City was a big city after all, and the situation was better than that of Napal Mountain City.

Part of the wall to the north was burned, as were some of the houses along the wall.

But many of the houses in the city were still there, and he could even see the orcs coming in and out of the houses from the sky.

The warehouses in the city that used to store supplies have been burned down, and it seems that it should be a fire that was lit by itself when the human army retreated.

The orcs in the city saw Xiao Feng's Black Shark helicopter flying overhead, and they also got out and yelled at his helicopter, and even some guys kept waving their weapons in their hands to demonstrate to him.

If it was before, Xiao Feng would definitely lower his height and teach these guys how to behave, but this time he didn't pay attention to them.

Instead, he went straight to the south, Qukai City had fallen, and it was impossible to hold the Hulu Gorge, so only Rushing City might still have hope to hold it.

So at this time, Xiao Feng was like an arrow along the way, and he just wanted to return to Rushing City as soon as possible to take a look.

He went all the way south, and the farther he went, the more black smoke filled the air, passing over the gourd gorge, and everywhere the traces of human resistance could be seen.

In the middle of the Gourd Gorge, the castle he had Charisman built had been reduced to a pile of ruins.

He even saw from the air that there were orcs ripping up the corpses of human soldiers from the rubble and pulling them out, and some bastards were even desecrating the corpses of those human soldiers...

Xiao Feng didn't bother to pay attention to it, he was like an arrow at this time, he just wanted to rush back to Rushing City as soon as possible to see if the city was still there...

"Shoot the arrows!"

Loud shouts were heard in the distance, and the officers were at various firing positions on the top of the tower, directing the rhubarb shooters, constantly firing giant crossbows into the sky.

In the air, there were several huge black shadows, constantly passing through the black clouds, but they did not rush down immediately.

Humans and these dragons have been scorching on the city for more than ten days, and now the situation on the battlefield is constantly changing.

The human army has gone from being defeated at the first sight of this prehistoric beast to now having their minds set, but they have risen up and put up a stubborn resistance in the city.

In the beginning, the orcs could still rely on the power of the dragon to repeatedly raid and succeed, and even behind the walls of Rushing City, a small half of the unfinished armed fortress had been burned by them.

But when humans began to use the rhubarb crossbow to shoot seven or eight dragons in succession, the situation on the battlefield gradually stabilized.

The orcs found that it wasn't because of the dragon that they could be invincible.

And the human race also found that those ancient beasts were not invincible, at least as long as they could make reasonable use of the big killing weapon left by the mage, they could also cause serious damage to the dragon.

These fire-breathing beasts, swooping down from the air, look amazing, but their means of attack are actually very simple, and the range of their fire-breathing is only fifty meters, to more than one hundred meters.

And the number of times a day to breathe fire, is only a few dozen, and if you do more, you will be exhausted.

And the mage, the air defense tower left for them, can fight this kind of dragon very well.

With a concrete wall more than a meter thick, even if the dragon's fury is strong, there is nothing to do with such a thick stone wall, and whenever they swoop, just let the archers of the big yellow crossbow aim at them.

Just one arrow can cause irreversible damage to these dragons, and even if one arrow doesn't kill them, there is a second arrow, a third arrow...

Kaluhan pushed the rhubarb crossbow hard, aiming at the flying dragons in the air, and Hansen and Fisher beside him had already used the noose to chain the two-meter-long spear.

The bowstring made of twisted vines mixed with crocodile tendons gives the giant crossbow in front of it super tension, and when the bow is full, the effective range of this giant crossbow can reach a thousand meters.

This is the range that Kaluhan personally tested when he practiced operating this giant crossbow before, and when shooting upwards into the sky, taking into account various angles and wind speeds, the effective killing range of this giant crossbow can also reach between 500 meters and 600 meters.

There are four people in his rhubarb crossbow shooting team, he is the main shooter, Hansen and Fisher, who are responsible for powering the giant crossbow, are the second and third marksmen, plus Charles at the observation post, they form their shooter team.

And a squad of shooters like them, on the top of this tower, there are sixteen groups, everyone defends in pieces, and there are two groups in almost every direction.

And in the walls of the Rushing City and the fortressed city behind it, there are a total of twenty-six air defense towers like them.

There were sixteen on the city walls, and ten in the city.

Now, he has gone from the horror and fear when he first saw the dragon to calm down.

Especially after the baptism of fire and blood, after more than ten days of confrontation, he has sacrificed four comrades-in-arms, and he has also changed from the original observation post to the main shooter.

He even shot a dragon with his own hands, and his ultimate goal was to shoot as many dragons and orcs as possible before he died.

"The orcs are coming, and the shooters of Fort Fusen, Chikla, and Fort Highgel adjust their shooting boundaries. Titanburg, Poseidon Castle... Continue the realm and protect the top of everyone's heads... ”

A series of shouts suddenly sounded on the city wall, and the loud herald passed General Kyle's orders from the left side of the city wall to the right side.

Each anti-aircraft tower on the city wall has its own name.

The air defense tower where Kaluhan is located is Fort Fusen, and their location is at the key checkpoint on the hill where the city wall stretches.

Originally, the city wall of Rushing City was just a section of the city wall built along the mountain and stretched to the side of the rushing river more than 100 meters long.

In the following years, with the continuous expansion of human territory, this city is no longer at the forefront of facing the orc soldiers, but the humans who suffer from the fear of force against the orcs have not stopped building the city's city defense.

The original 10-meter-high and two-meter-wide city wall has now been expanded into a 50-meter-high and eight-meter-wide giant wall.

Even the mountain on the right, facing the north, was transformed into a city wall, and the originally steep mountain was split by them to 90 degrees.

The walls stretch from more than 100 meters to the slopes of the hill to the top of the steepest mountain.

At intervals on the city walls, a tall anti-aircraft tower was also built.

Of course, the reason why such construction can be completed is also thanks to the dwarves in the tribe who are very good at dealing with stones and good at construction, as well as the hundreds of thousands of half-orc slaves who have been captured.

Especially those who drilled the beetle, and the rabbit people, and the rat people, these slaves who were good at civil engineering, made great efforts in the construction of the city defense.

It is not an exaggeration to say that under every meter of the city wall, there is a corpse of a half-orc.

And this city wall also played a role in the confrontation in these ten days.

The orcs and their hundreds of thousands of troops, plus the dozens of dragons they looted as support, still have no way to take this impregnable fortress.

Kyle looked at the large formation of orcs slowly advancing on the opposite side, he couldn't remember how many times the orcs had rushed into the city, because of the terrain restrictions, the width of the battlefield in front of Rushing City suitable for spreading formations was only more than a hundred meters, which relieved them of a lot of pressure on the humans defending the city.

The city wall is more than fifty meters high, and he is not afraid that these half-orcs can climb up.

After a few days, the orcs hit their heads in front of Rushing City and bled out, leaving at least tens of thousands of corpses in front of the city walls, which also made him gradually calm down.
