After a short flight, the rock quickly fell on the city wall and collided violently with the shield.
The powerful impact force slammed into the aura shield, causing it to shake wildly.
Cracks began to appear, the sound of collisions was like thunder, and the faces of the Jinzhou City defenders below turned pale.
Fortunately, the first round of boulders did not cause much damage to the shield after it hit it. Although there were cracks in many parts, it still held up and did not completely break.
However, before everyone could breathe a sigh of relief, a second rock appeared in the hands of these giants.
After another roar, the rock came crashing down on the top of the city again at lightning speed.
"Stop attacking the giant with your heavy crossbows, and shoot at the boulders in the air!!!"
At the critical moment, Ye Li suddenly gave orders on behalf of Bian Yingxiong.
Bian Yingxiong also reacted extremely quickly and shouted: "Listen to Ye Li, quick!!!"
The soldiers of Jinzhou City were very well-trained. In an instant, they adjusted the direction of their heavy crossbows and began trying to shoot at the boulders flying in the air.
However, it was an attack launched in a hurry, and it was very difficult to shoot at the boulders. The attack of the heavy crossbow only hit four rocks.
This time, the heavy crossbow was unable to penetrate these boulders directly. It seemed that the concentration of earth-based spiritual energy on these boulders was even greater than that of the ten rock giants below.
Ye Li also suddenly reacted after the first round of attacks. Those giants could deliberately soften the earth-based spiritual energy on their bodies to defend against the attacks of heavy crossbows, but in order to gain powerful destructive power, these rocks must be hard enough.
Otherwise, if only mud balls with a diameter of seven or eight meters hit the defensive shield, they would basically not cause any damage.
In this case, since the rock is very solid, the attack of the heavy crossbow cannot penetrate it easily. The crossbow arrows that remain in the rock will explode and will inevitably cause great destructive force on the rock and shatter it.
Ye Li's idea was undoubtedly very correct. Four of the ten rocks were directly blown up by the bombardment of the crossbow arrows, turning into a group of smaller scattered rocks that hit the defensive shield.
Although they still have considerable lethality, their impact capability is definitely not as good as before, and they do not cause much damage to the spiritual shield in the hit area.
However, the remaining six rocks that were not blown up still hit the already damaged spiritual shield heavily.
After this impact, a large area of the spiritual shield began to show signs of collapse, and the cracks spread to every shield on the entire city wall.
The rune formation on the city wall could not completely repair the spiritual shield in a short period of time. The shield had reached its limit at this moment. If it was hit by another huge rock, it would definitely be completely shattered.
At this time, the rock giants had indeed raised the rocks for the third time. Their third round of attack was about to come. The powerful oppressive force had already acted on the hearts of the Jinzhou City guards from a long distance.
"Hold on, the heavy crossbow must be aimed and attacked, and the rocks must be destroyed in the air!!!"
At this moment, everyone's hope has been focused on the heavy crossbow. If the heavy crossbow can destroy all the rocks in this attack, then those scattered rocks will most likely not have much impact on the spiritual shield.
This spiritual shield that is on the verge of collapse should be able to barely withstand another round of impact from shattered rocks.
"Look, those giants seem to be dying!!!"
Suddenly a soldier shouted.
Ye Li looked at the ten giants under the city, condensed the earth spiritual energy, and combined it with solid mud and rocks to form a huge rock ball, which seemed to be a huge consumption for the giants.
After throwing three huge rock balls in succession, the bodies of the ten giants suddenly shrank, from thirty meters high to ten meters in size, as if they had suddenly turned from adults into children.
Although the height of ten meters is still huge, it is not much of a threat compared to the city walls of this majestic city.
After these rock giants shrank, they began to retreat and had no intention of continuing the attack. It was obvious that they no longer had the ability to attack the city.
The giant birds that had originally gone far away in the sky had been hovering above the city wall again since no one knew when. At the moment when the third round of rocks hit the top of the city wall, they began to swoop down, with golden light all over their bodies and sharp energy that seemed to cut the air apart.
The soldiers operating the heavy crossbows on the city wall have already shot out the huge powerful arrows. This time they were prepared, and at the critical moment they seemed to have performed at an extraordinary level of aiming skills.
Dozens of heavy crossbows completely locked onto the ten boulders, and after a moment, they would collide with each other.
The soldiers on the city wall began to show a hint of joy on their faces.
However, accidents always happen at the last moment. Just when the arrow of the heavy crossbow was about to hit the rock, more than a dozen golden lights suddenly hit the huge arrow.
The body of the giant golden bird turned into a stream of light and collided with the arrow with extremely strong force.
The impact force of the arrows all acted on the giant bird, and their directions were changed by the impact of the giant bird. Most of them flew out along the rocks, and only a few pierced the two rock balls.
The arrows that had come to a complete stop after being hit by the giant bird suddenly exploded, tearing the giant bird's body, which had turned into golden light, into pieces.
In the blink of an eye, more than a dozen giant golden birds turned into balls of golden spiritual energy and dissipated in the air.
"Damn it, be careful to dodge!!!"
Seeing this situation, Bian Yingxiong, who had been smiling, turned pale in an instant.
He had never expected that such a change would occur at the last moment.
Among the ten rocks, only two were broken, while the remaining eight rocks hit the protective shield that was on the verge of collapse with extremely strong force.
Suddenly, there was a crisp sound, and the defensive shield could no longer withstand the impact of the rocks. It shattered with a loud bang. The heavy rocks smashed down on the many soldiers who had no time to dodge with their final inertia.
"Boom boom boom..."
After a series of roars, eight pools of bright red flesh and blood appeared on the city wall.
Under the powerful impact of the huge rocks, hundreds of soldiers were directly hit by the rocks and instantly crushed into meat paste.
Four other heavy crossbows were also hit by the rocks and smashed to pieces, becoming completely unusable.
