Knock, knock, knock......

The rousing drums of war came from the rear of the Imperial Army, and at this moment the Empire's more than 300,000 troops were advancing towards the Black Earth Fortress.

In the face of the towering pitch-black walls, the Imperial soldiers did not fear, but maintained a neat line and advanced at a uniform speed.

At the forefront of the Imperial army was a large platoon of heavy shield soldiers, the shields in their hands were raised diagonally, and there would be no enemy in front of them, and the deadly attack must have come from the fortress dozens of meters high.

The heavy shield soldiers were very special, they wore light armor, and they did not even carry weapons, and each carried a bamboo basket on their backs, and inside the bamboo basket were irregularly shaped large and small stones, which were the key to the battle.

The front of the Imperial army was lined up in a queue of this size, with heavy shield soldiers in one shot, transport soldiers carrying stones on their backs, and heavy shield soldiers in the back, and so on.

As the Imperial army advanced, the tribal armies on the walls of the Black Earth Fortress tensed up.

On the edge of the fortress walls were large caramels of crossbows, which were forged entirely of metal like gun emplacements, and had to be reloaded with a wheel, which resembled the starting lever of an old-fashioned walk-behind tractor, but with an enlarged model.

Click, click, click......

The sound of the crossbow winding is continuous, this kind of large machine crossbow can not be wound in advance, it will not be launched within a minute after winding, and the strong pull of the bowstring will deform the crossbow, which shows how terrifying the power of this thing is.

A dwarf is busy on the city wall, there are three dwarves near each machine crossbow, one is responsible for firing, one is responsible for loading, one is responsible for winding the wheel, their movements are neat, less than ten seconds, more than 300 machine crossbows on the city wall have completed the winding, don't think that there are only these three hundred machine crossbows on the black soil fortress, look around, there are at least a thousand machine crossbows on the fortress, but the battle line is so long, other machine crossbows are not used, this kind of mobile machine crossbow has filled this section of the city wall.

Before the Imperial Army attacked the Black Earth Fortress, it was almost a one-sided massacre of the tribesmen, and as for counterattacking with a rain of arrows, it was basically ineffective.

This terrifying weapon of war, known as the 'Castle Protector Heavy Wheel Crossbow', was invented and crafted by the dwarves.

If the 'City Protector Heavy Wheel Crossbow' only fires ordinary large crossbow arrows, then the tribe side will not use it to defend the fortress, no matter how powerful the crossbow arrows are, it attacks only one point, and has little effect on the battlefield of hundreds of thousands of people, but the attack range of the 'City Protector Heavy Wheel Crossbow' is not a point, but a large area.

"Ready."

A dwarf almost wrapped in an iron bucket stood on a high place, holding a small red flag.

By the time the dwarven bannermen raised their small flags, the Imperial army was already in the middle of the pack, and the soldiers with bamboo baskets on their backs rushed out, and they untied the bamboo baskets behind them as they charged, trying to dump the stones in the bamboo baskets under the walls, and as long as they completed this 'easy' task, they could retreat to the rear of the army.

Unfortunately, they didn't have that chance.

"Rush!"

One soldier after another rushed forward.

"Fat!"

On the fortress, the dwarves waved the chess pieces held high, and the dwarves behind the three hundred 'heavy wheel crossbows' pulled the trigger hard.

Collapse, collapse, collapse......

The crossbow string made a muffled sound, which was not a broken crossbow string, but the sound of the crossbow string being too strong and quickly rubbing the air.

Crossbow arrows more than three meters long are shot one by one, these crossbow arrows are not pointed, but oval arrows, like a large match, the crossbow arrows are interrupted by several rows of reverse air holes, once the speed of the crossbow arrows reaches a certain limit, this killing weapon will show its hideous side.

The entire body of the bolt is in a spiral, so it starts to spin at high speed after the bolt is fired.

Bite~

A large crossbow arrow stretched out in mid-air with a circle of 'wings', which were some kind of wings, but small double-edged blades three meters long.

The crossbow arrows are originally rotating at high speed, and after the double-edged blade is deployed, the crossbow arrows become reamers that rotate at high speed.

Airplanes~

A piercing whistling sound was heard, and hundreds of high-speed spinning crossbow arrow reamers struck the Imperial soldiers under the fortress.

The crossbow arrow reamer flew into the crowd and began to cut the human body, the armor could not protect this thing at all, blood and flesh were splashed, and more than a dozen soldiers were instantly chopped into flesh, this is not the end, because the tip of the crossbow arrow reamer is round, and it will continue to strangle the enemy after landing, if the angle is just right, this thing is like a spinning top.

Dirt splattered, stumps flew sideways, and after a volley of Horde troops, a large body appeared under the fortress.

"Hahaha."

"These crumbs."

"Come again."

While the dwarves on the fortress burst into laughter, a second salvo was ready.

Under the fortress, the face of the legion commander Carlos was grim, and beside him was a severed crossbow arrow reamer.

"Go on."

Carlos roared and heard the voice of his own captain, who rushed forward with a roar of soldiers carrying bamboo baskets, their captain looking at them, the man they admired.

Collapse, collapse, collapse......

The second volley of fire on the fortress began, and although the Imperial soldiers suffered heavy casualties, under the leadership of the corps commander Carlos, groups of soldiers rushed forward without fear of death.

In less than two minutes, the stones under the fortress had been piled up to a meter high, but of course the stones did not have this effect, and it was different if you added the broken corpses.

While the dwarves on the fortress were busy reloading, the elven archers in the rear of the Imperial army had been preparing for a long time.

Sou~

The dense rain of arrows shot above the fortress in a parabola, seeing these arrow rains, the dwarves on the fortress didn't care at all, the role of the 'city protection heavy wheel crossbow' was originally invented, in fact, it was not to defend the city, but to deal with the arrow rain of the elves, but this thing is difficult to carry, and it is not effective to deal with the elven archers who are light in action.

But now it's a siege battle, and the 'Protective Heavy Wheel Crossbow' has shown its ability to deal with a rain of arrows.

Before the dense rain of arrows fell in the air, one by one the crossbow arrow reamers had already met the front.

Click, click......

The rain of arrows was wrenched into sawdust, and not only that, but the crossbow arrows and reamers flew towards the middle of the Imperial army.

The crossbow arrows and reamers fell to the ground, and before the soldiers could scream, they were ground into pulp, and the situation of the tribal army was very good.

Is this the case? No, once the pile of stones + corpses under the fortress accumulates to a certain height, the imperial army will rush to the fortress and start a white-knuckle battle.

Strangely, there was no large-scale magic in the armies of both sides, and there was no fire rain spell or wind rush technique.

It's not that there are no mages in both camps, but the casters in this world are not very strong in group combat, and if they are one-on-one, the caster's ability is not weak, and as for large-scale magic, that thing has never appeared since the establishment of the empire, and the specific reason is unknown.

Today's spellcasters rarely participate in wars, they prefer to explore magic, that is, they do not participate in the struggle for power, as for the second-order contractor mage, they are less likely to master large-scale magic, mass destruction magic is not available at this stage, and the mana value consumed by large-scale magic is also astronomical, and the second-order contractor mage is at most throwing small and medium-scale spells at the fortress.

The backbone of this world is the army, and the physical fitness of each soldier is not weak, and under the pressure of the army, no matter how strong the spellcaster is, he can only roll up the cover and flee.

At this time, Su Xiao was in the middle of the Imperial Army, on a small hill on high ground, and he was holding the Spider Empress.

Although the appearance of the Spider Empress in this world was a bit inconsistent, under the disguise of the Reincarnation Paradise, the other soldiers only thought that this was Su Xiao's special ability, similar to alchemy or magic.

Of course, Su Xiao was not the only one who used a sniper rifle on the battlefield, and in this special battle, the influence of the contractor on the war began to show.
