Yunjing Mountain, the vast spell formation's light shield disappeared in an instant.
As Lin Shiming roared, Lin Gang also realized what was happening and hurriedly waved the formation flags again, preparing to reactivate the formation.
But all they saw was a giant black millstone, like a small mountain, ruthlessly crushing down.
It firmly blocked the light shield's circulation.
Accompanied by the grating, harsh sound of grinding, the golden light shield continued to be worn away.
The spirit boats in the sky vanished in a flash, and about a dozen black-robed Heavenly Demon Sect Cultivators burst forth.
"Hehe, there's one who knows what's happening, but it's too late!" The leading black-robed cultivator revealed his cultivation level, and the spread of his Supreme Grade spirit might at the peak of Foundation Establishment became apparent.
Lin Shiming's body was so pressured that he could barely breathe.
"Yes, it's Chen Laosatan!" Lin Gang's face was also filled with shock. This person was one of the true disciples of the Heavenly Demon Sect. Although not a top direct disciple, his cultivation level and treasures were all among the finest in the Demonic Path, and only a demonic sect would be willing to spare such a genius disciple to raid for resources.
Apart from Chen Laosatan, the other demon cultivators also cast spells quickly, each with a cultivation level no less than the middle stage of Foundation Establishment.
Especially the black millstone wielded by Chen Laosatan, which clearly stood out even among third-rank Supreme Grade magic artifacts, could be seen in his one-handed spell casting, constantly driving it with spirit light after spirit light emanating, making the breach in the formation wider and wider!
"Laosatan, how dare you?" Lin Gang also roared angrily, waving his hand toward the sky, and a golden-horned green ox charged out with a bellow, heading straight for the millstone.
Meanwhile, Lu Changming's face also became unsightly. He waved his hand instantly, and two red luan birds flew out, attacking the demon cultivators from left and right.
The other Foundation Establishment cultivators also made their moves instantly, including Lin Shiming. At this moment, they stood to lose everything together, honor and disgrace intertwined. If the other Foundation Establishment cultivators died, as a disciple of the Three Sects, he would not escape death either, and he might even be captured to become a demonic leader or a demonic corpse.
The Tiangang Sword Formation and the Profound Heavenly Purple Wood Sword Formation were almost simultaneously deployed, their enormous momentum startling many people.
At this moment, Lin Shiming's divine sense, as a late-stage Foundation Establishment cultivator, was controlling the two sword formations, something that ordinary mid-Stage Foundation Establishment cultivators could not withstand.
On the other side, Lu Changming was also shocked, but Lin Gang was even more surprised. He remembered that divine sense; it seemed to be Lin Xianzhi's from that day when he had wondered how Lin Xianzhi, also a sword cultivator, could have a divine sense like that of a cultivator just entering the late stage of Foundation Establishment.
Now it appeared to be the divine sense of Lin Shiming, an early stage Foundation Establishment cultivator.
Lin Shiming's attacks were incredibly fierce, with his sword formations opening and closing forcefully, wielding relentless sword light and pressing down.
Ye Mingqiu's Magic Artifact was a Supreme Grade Third Rank one, and when combined with a tremendously powerful sword technique, his presence was no less imposing than Lin Xianzhi's.
The sword swiftly flew up into the sky, turned into a towering Gang Jian, and fiercely plummeted towards the Demon Cultivator's forehead.
The situation had largely improved, but it was still not looking optimistic. Several Foundation Establishment Middle Stage Cultivators from the Lu Family and the Ye Family had their magic artifacts contaminated, significantly diminishing their combat strength at this moment.
Even a Qi Cultivator at the Early Stage Foundation Establishment who originally belonged to Yunjing Mountain fell dead on the spot.
"Everyone, continue retreating to the Yunjing Mountain mines and wait for reinforcements!" Lin Gang was still firing off multiple Spirit Talismans.
He attempted to send out messages, but then he saw the last of the Demon Cultivators, whose black robe suddenly began to inflate like it was being filled with air, swelling continuously.
In the next moment, black banners emerged from his body and were swiftly thrown towards the walls surrounding Yunjing Mountain.
Out of nowhere, ten flags infused with Spiritual Energy appeared as Demon Banners, spewing out black smoke that obscured the sun.
"Is this the Ten Sons Heavenly Demon Formation?"
And all of Lin Gang's messages were devoured by the black fog, clearly signaling the failure of message transmission.
"Chen Laomo, you're really willing to go all out!"
Lin Gang could only resentfully launch a Flying Sword, which violently shattered the black millstone, and he began to retreat while fighting.
Now without a Formation, there was no way to contend with the Heavenly Demon Sect's Demon Cultivators. It was better to head to the mines, where Xu Daolai's Third Rank peak Spirit Beast could deal with these Demon Cultivators.
As Lin Gang retreated, his Spirit Beast, the Golden Horned Green Ox, also let out a series of bellows and began to retreat.
As Lin Gang pulled back, Lu Changming's pressure intensified. Various black demon hands reached out to grab him.
"Retreat!" Lu Changming, with a hard look at Lin Gang and cursing him inwardly, also quickly retreated.
Ye Mingqiu and Lin Xianzhi, facing Heavenly Demon Sect Cultivators who were at the later stages of Foundation Establishment, nodded to each other and both withdrew together.
And Lin Shiming, at the rear, had already steered the Spirit Boat to retreat towards the mines.
Although many Cultivators of the Three Sects were injured, fortunately, only one had perished. As long as they gathered together and prepared the Formation well, with the assistance of the two great Sword Cultivators, Lin Xianzhi and Ye Mingqiu, there was still a great chance of success.
