The ant-biting elephant tactic was ineffective, spell attacks were ineffective, and Spirit Treasure Spirit Artifact's attacks were ineffective. After repeated setbacks, Nine-Tailed Celestial Fox Grand Elder decided to use boulders to bombard him instead.
"Go around to the back of Ping'an City!" Nine-Tailed Celestial Fox Grand Elder ordered.
Following Nine-Tailed Celestial Fox Grand Elder's order, Qingqiu City's army moved to the battlefield and circled behind Ping'an City, making it easier to get boulders or hills from the Great Luo Mountains.
Seeing Qingqiu City's army going around behind Ping'an City, Lin Zihan worriedly said to Jiang Ping'an, "Those foxes may want to attack Ping'an City with boulders."
Using boulders to attack and defend a large formation is a common attack method.
Lan Yu and Palace Master Yunshui also looked worried.
"If they really do this, they are seeking their own death!" Jiang Ping'an smiled confidently.
Lin Zihan, Lan Yu and Palace Master Yunshui looked at Jiang Ping'an in surprise.
Jiang Ping'an smiled and said, "Zhu Yan has Sky Banishment magical powers, and I have also practiced a spell that can make the ground Heart Force soar ten thousand times., this spell is called Hou Tu Suppressing God Art. The combined use of Sky Banishment's magical power and Hou Tu Suppressing God Art is guaranteed to cause heavy casualties to Qingqiu City's army."
"If so, it is indeed so." Lin Zihan, Lan Yu and Palace Master Yunshui nodded expectantly.
Jiang Ping'an showed a hint of worry and said, "It's just that I'm a little worried that Qingqiu City can't afford to lose. It would be troublesome for their Heavenly Fox Demon Emperor to take action personally."
Lan Yu smiled and said, "Mr. Lang, why have you become hesitant? Those foxes are coming to kill us and want our lives. Of course, we must kill them first!"
"Yes, that's how it should be!" Lin Zihan also said.
Jiang Ping'an smiled self-deprecatingly, "Haha, Lan Yu is right. Then, let's make a big one!"
After the Qingqiu City army circled behind Ping'an City, they did not launch an attack immediately. Instead, they stopped to rest and recover their demon power.
Jiang Ping'an also led the main defenders to move to the rear of Ping'an City.
The next day, the Qingqiu City army did not attack. They were digging boulders, cutting mountains, etc. to prepare ammunition.
Inside Ping'an City, the monks standing on the hundred-foot-high city wall could see the Qingqiu City army preparing boulders from a distance. How could they not guess that the Qingqiu City army was preparing to use boulders to attack the city?
They were very anxious and asked Jiang Ping'an to come out of the city to interfere.
"Qingqiu City's troops far exceed ours. If we go out to interfere in the city, we will only fall into their trap." Jiang Ping'an rejected the monks' request.
The Qingqiu City army prepared boulders for ten days in a row, and finally started to attack Ping'an City with boulders.
"All demon emperors, demon kings and big demons obey the order," Nine-Tailed Celestial Fox Grand Elder ordered, "Half lift the boulder to Ping'an City high in the sky and release it, and the other half are on guard to prevent Human Race from taking the opportunity to counterattack!"
"Be careful of Ye Chenzhou and his maid Jade Transformation Divine Light, they will bring the boulder to Ping'an City more than five hundred feet high and then smash it down!"
Following Nine-Tailed Celestial Fox Grand Elder's order, half of the Heavenly Fox Demon King, Fox Race Demon King and Fox Race Great Demon used their demon power to lift the boulder and fly high into the sky.
The demon kings and big demons of other races recruited by Qingqiu City also used their demon power to lift the boulders and raised them high into the sky.
However, there are not many demon kings and great demons from other races, mainly Fox Race.
For a time, countless boulders rose into the sky, large or small, and they were so densely packed that they looked numb.
The largest ones are undoubtedly the four stone mountains, which were lifted up by the four Nine-Tailed Celestial Fox Demon Emperors with their demon power. Each one is about tens of feet high and weighs more than a million kilograms. To lift such a heavy rocky mountain, the four Nine-Tailed Celestial Fox Demon Emperors were exerting their full strength.
The small boulder is about one foot long, wide and high, and weighs about two hundred thousand kilograms.
After lifting the boulder with all their strength, the Demon King, Demon King and Big Demon were basically unable to dodge and defend, so the other Qingqiu City troops who did not lift the boulder flew ahead to prevent the Human Race monks from attacking.
Under the command of Nine-Tailed Celestial Fox Grand Elder, all the boulders were lifted into the air more than five hundred feet in advance, and spread out to a range of fifteen miles wide and two or three miles long.
The purpose of spreading out is to avoid being concentrated by the Human Race monks, but it should not be too spread out, otherwise the attack will not be concentrated and the effect will be ineffective.
"Forward!!!" Nine-Tailed Celestial Fox Grand Elder shouted loudly.
The Qingqiu City army at the front immediately flew closer to Ping'an City, and the Demon King, Demon King and Big Demon, who were holding the boulder more than five hundred feet in the air, flew towards Ping'an City.
Ten miles away from the Ping'an City wall, Nine-Tailed Celestial Fox Grand Elder and other four-headed nine-day Heavenly Fox Demon King first cast high-level large-scale spells to attack Ping'an City, to suppress the Human Race monks inside Ping'an City and prevent the Human Race monks from leaving the city to counterattack.
Finally, the Qingqiu City army approached five miles from the Ping'an City wall.
Under countless attacks, the Human Race monks in Ping'an City seemed to be completely suppressed.
Nine-Tailed Celestial Fox Grand Elder ordered while full, "Boulder attack!"
More than five hundred feet in the air, countless boulders began to fly further into the sky above Ping'an City.
At this moment, Zhu Yan, who had already released his three-hundred-foot-long true body, suddenly burst into defensive light, jumped off the city wall, rushed out of the defensive cover, and charged towards the Qingqiu City army with all his strength.
Lin Zihan and Palace Master Yunshui chased after Zhu Yan and worked together to help Zhu Yan block countless attacks. Lan Yu also followed behind, casting Jade Transformation Divine Light, scanning and attacking Zhu Yan's spell and Spirit Artifact.
"Stop it!!!" Nine-Tailed Celestial Fox Grand Elder shouted hurriedly, and it also used Starfall Fire Pearl to attack Zhu Yan.
Although, it can't guess what Zhu Yan is going to do.
For a time, countless attacks focused on Zhu Yan.
Although Lin Zihan and Palace Master Yunshui tried their best to help Zhu Yan block the attack, and Jade Transformation Divine Light protected it, Zhu Yan was still inevitably attacked. However, Zhu Yan has extremely strong defense, and those attacks can only damage it.
In the blink of an eye, Zhu Yan rushed out of Ping'an City for more than ten miles and rushed into the Qingqiu City army.
Roar——
Zhu Yan looked up to the sky and roared, displaying Sky Banishment's magical power.
For a moment, everything flying in the air within a radius of thirty miles plummeted involuntarily, and even the Demon King could not avoid it.
The Demon Emperor, Demon King and Big Demon who were lifting the boulder with all their strength all fell straight down. They panicked and tried to stabilize their bodies, but they couldn't do it at all. Even if they wanted to move sideways to avoid being crushed by the boulder, they couldn't do it either.
Ahhhhh——
Countless demon emperors, demon kings and great demons couldn't help but scream in panic and fear.
Except for the Demon Emperor, Demon King and Big Demon who were holding up the boulder, the rest of the Qingqiu City army also fell straight down.
At the same time, Jiang Ping'an suddenly appeared out of thin air among the army of Qingqiu City.
It turned out that when the Qingqiu City army was gathering fire Zhu Yan, he had already cast Void Escape, flying through the void towards the Qingqiu City army.
I saw Jiang Ping'an's whole body Meridians opened wide, and he quickly pinched the magic formula and displayed Hou Tu Suppressing God Art.
A huge Buzhou Mountain phantom appeared across the sky, covering a radius of two to thirty miles. Under the phantom, the gravity instantly increased ten thousand times.
The straight-falling Qingqiu City army and boulders accelerated thousands of times and fell as fast as a meteor.
Seeing that they were unable to withstand Sky Banishment's magical power, those demon emperors, demon kings and big demons who used all their strength to attack Zhu Yan with their spells were suddenly subjected to 10,000 times gravity, and their spells were immediately interrupted. Even the demon emperor was no exception.
