The battle broke out instantly in the earth-shattering roar of the demon army, and the first to attack was the catapult and the giant crossbow of the defenders of Black Rock City, and the boulders fell from the sky with a whistling sound of breaking the air, just like the mountains flying in the distance, smashing into the camp of the demon army in the distance, and the dozen or so city defense giant crossbows with a range of about 300 meters also shot the giant arrows on the crossbow machine in the form of projectiles. At this time, the demon army was still four hundred meters away, even if it was projectile, it could only barely reach the most marginal soldiers, and the power of landing had been greatly reduced, and it was difficult to cause effective damage to the enemy, but this was what Mu Yang meant, and he told him to do his best to stop the demon army one hundred and fifty meters away.

Ge Tianbing didn't understand why Mu Yang suddenly made such a warning, but he still chose to obey it and gave the order to attack as soon as possible.

Seeing the boulders and crossbow arrows falling in the air, there was a sudden rush of screams from the demon camp, and the more than 2,000 cavalry gathered together retreated one after another, and the speed was amazing, except for a few people who were hit by the boulders and gravel that fell to the ground, no one was injured.

Ge Tianbing's eyes instantly widened, and he looked at the retreating demon army with an incredulous expression: "None of them died?"

Mu Yang stood beside Ge Tianbing, looking at the blue-armored general riding on a war horse under the rear general of the demon army, and said nothing. Sisi held the antler bow, his eyes constantly wandering between the demon army camps, and there was not the slightest fluctuation of emotion on his calm face. Ye Yu's face was flushed, and his little hand holding the five-colored golden lotus was clenched tightly, and there was a faint excitement in the nervousness.

The catapults in the city were still throwing boulders, and the demon army outside the city had retreated to a distance of five hundred meters, which was just beyond the coverage of the stones, and then, half of the warriors on their horses dismounted, and the other half retreated to the sides.

The dismounted warriors crossed their horses, raised their shields one after another, and soon formed a dozen long shield arrays, quickly rushing towards the city.

Mu Yang stood on the city tower, looking at the heavy steel shield held high in the hands of the demon army and the strong physique with knotted muscles, his expression was extremely cold.

Demon people are fierce, all of them are natural warriors, in terms of combat effectiveness alone, a male adult demon has the strength of a human martial star realm cultivator at least, and on the battlefield, it means that it takes three to five ordinary human soldiers to compete with it.

The warriors of the Blood Skull Legion are obviously much stronger than ordinary demon warriors, and it can be seen from their nearly two-meter bodies and the momentum emanating from their bodies that everyone's combat power should be around the seventh rank of the Martial Star Realm, some low-level generals even surpass the Second Realm, and there are some cultivators who exude the light of the star element in the middle, this is a real elite demon army.

Seeing the square steel shield held high in the hands of the demon army, Ge Tianbing's face became extremely ugly, and at a glance, he could see that this one-inch-thick steel shield was definitely not something that the longbows in the hands of his soldiers could shoot through.

The demon army quickly entered the range of the catapult, and another wave of boulders and giant crossbows were shot out, Ge Tianbing's eyes fell to the demon army camp with the trajectory of the boulder flying out, and a sneer appeared at the corner of his mouth, in his sight, there were several boulders falling in the direction of the demon army's shield array, he really wanted to see how these blood skeleton warriors relied on the shield in their hands to block the bombardment of nearly a hundred catties of boulders.

However, the scene that caught his eyes made Ge Tianbing's pupils shrink suddenly. He saw that at the moment when the boulder fell, the demon army shield array that was running rapidly on the ground suddenly moved a few meters to the side, and it just avoided the route of the boulder landing, and several shield arrays were even directly dismantled into smaller five-person small formations, and after dodging the attack, they quickly retracted, as if they knew the direction of the boulder's fall in advance.

This wave of stone-throwing only caused more than a dozen casualties to the demon army.

Ge Tianbing was a little stunned, in the years he had been the city lord, he had read a lot of books on the art of war, but he had never heard of any army that could dodge the slings and giant crossbows so accurately in the charge. At least, his men can't.

The catapult and the giant crossbow were fired at an interval of about ten breaths, and when another wave of boulders was thrown, the demon army was already less than three hundred meters away from the city.

At this time, with a military order, the bowstrings of the soldiers and hunters on the city wall who had long been tense were loosened almost at the same time, and more than two hundred sharp arrows flew diagonally into the air, condensing into a rapidly falling black cloud and slamming heavily on the shield array of the demon army, making an aggressive tremor sound.

As Ge Tianbing expected, most of the arrows that fell were blocked by the shield, except for a few that passed through the gaps in the shield and hit the demon army's body.

"Damn, this is still cavalry, it's all steel shields!"

As the demon army approached, the catapults and the city's defense crossbows had lost their effectiveness, and only the longbows in the hands of the defenders kept making a buzzing and trembling sound, shooting sharp arrows out of the city, but the damage caused was extremely limited.

The demon army shield soldiers are constantly approaching, less than two hundred meters away from the city gate, the bow and crossbow in the hands of the defenders finally gradually began to play a role, at this moment, not far from both sides of the city gate, the sound of rapid horse hooves suddenly sounded, one left and one right, two three hundred demon army archers galloped towards the city gate, about one hundred and fifty meters away from the city gate, the archers on the horses released arrows one after another, the dense flying arrows forced the defenders on the city tower to lean over and dodge, after five rounds of arrow rain, the two demon army archers crossed in front of the city gate, when the defenders raised their heads again, the shield array in the distance advanced more than fifty meters。

At this time, Mu Yang's voice suddenly sounded: "Let everyone squat, dodge, quickly." ”

"What?" Ge Tianbing was just about to command his subordinates to release arrows, when he heard a sound.

"Everyone squat down, be careful to throw the spear!" Mu Yang's voice sounded in Ge Tianbing's ears quickly, almost subconsciously, although he didn't know where the spear came from, Ge Tianbing still let out a loud shout: "Squat!"

At the same time as Ge Tianbing's shout, the steel shield above the head of the demon army shield soldiers one hundred and fifty meters away from the city suddenly pointed to all sides, revealing a spear thrower with a short spear below, and the tacit understanding of long-term coordinated combat made these spear throwers throw the short spear in their hands at the moment when the shield disappeared, and the shield soldiers around them suddenly increased their speed, and with the flying short spear quickly rushed towards the city wall, they were followed by more than a dozen strong men who were half-naked and carrying siege ladders.

Ge Tianbing, who was hiding behind the battlements of the city wall, saw this scene and his face changed drastically, he never thought that the cooperation of the demon army would reach such a terrifying point, and what shocked him deeply was the distance of those spear throwers throwing flying spears, one hundred and fifty meters, which was more than the effective range of the Xia army's crossbowmen. The speed of the spear thrower is even more amazing, the first spear has just flown out less than fifty meters, the second spear has been shot, and when the third spear is thrown, the first one has just fallen, that is, if a spear thrower keeps throwing spears, it means that there will always be four short spears flying in the air, and the interval between each two spears is less than half a breath!

With such a dense attack, the defenders on the suppressed city wall did not dare to raise their heads at all, and several soldiers who wanted to fight back just stood up, and before they could pull the bowstring, they were shot through the body by flying spears, and it was only at this time that Ge Tianbing realized the horror of the Blood Skull Legion, and immediately sweated like a waterfall.
