Countless magical spells instantly engulfed the black stone gate and the hundred-zhang area around it.
The attacks from all humans and demons were extremely clear and concentrated, aimed directly at the black stone gate.
However, these violent and focused attacks only managed to kill seven or eight demon monsters that rushed out of the black stone gate. They caused no damage to the black stone gate, which appeared to be simply constructed from ordinary stones.
"Sect Master, this is a big problem!
This is a teleportation gate from the demon realm! Unless a Golden Immortal from the Upper Realm intervenes, it cannot be destroyed!"
After a round of fierce attacks, Jin Jialin stopped attacking and transmitted his voice to Yang Hong using his divine sense. Clearly, he did not dare to publicize this information.
Yang Hong retorted, "How did you know?"
"It's in my inherited memories. My father was a Golden Immortal level demon immortal, a Thunder Eagle. He descended to this realm precisely to destroy a demon realm teleportation gate. That's how he met my mother and how I came to be.
"Is that so? I understand."
Yang Hong nodded and also stopped attacking. Items of seven-colored destiny indeed possessed extraordinary qualities.
He observed silently for a quarter of an hour before issuing his orders:
"Halt!
Ye Yudong, Ran Boren, Qiu Kun, divide yourselves into three teams and take turns attacking the demon monsters emerging from the teleportation gate. Each team will guard for one hour, and you must switch promptly when your time is up to conserve your spiritual power and energy.
"Jin Jialin, Zhuiyun Chongshan, Hong Xuanji, you will also divide into three teams and maintain continuous assault!"
"As you command!"
Following Yang Hong's orders, the disciples of Qingfeng Mountain Villa spread out into three groups. Apart from some who occasionally unleashed spells to kill the emerging demonic creatures, the others landed on the ground to recover their spiritual power.
After fifteen days of traveling over 200 million li, they were all extremely exhausted. Besides spiritual power, they needed to recover their mental energy even more.
After arranging the disciples, Yang Hong frowned again and spread his divine sense to survey the interior of the entire formation space.
"This won't do. The demonic creatures appearing now are only at the third-tier Fusion realm. Ten Foundation Establishment disciples focusing their attacks can kill them.
However, these low-level demonic creatures are merely coming out to die and to channel demonic energy!"
His divine sense was powerful, and he could detect that after the demonic creatures died, wisps of pure demonic energy dispersed and directly merged into the surrounding heaven and earth, especially into the ground beneath their feet.
He was not foolish; he saw the demons' objective at a glance.
Their plan was to dispatch countless cannon fodder to transform this land directly into a demon domain. At that time, this teleportation gate would inevitably expand, allowing more powerful demons to descend.
Furthermore, once this place became a demon domain, a demon's home ground, their combat power would increase, while cultivators would be significantly suppressed.
Since the demons' plot had been discovered, it had to be thwarted promptly.
The primary issue was to purify the demonic energy. Since the teleportation gate could not be destroyed or closed, they had to completely contain its location.
He then summoned Zhuiyun Chongshan, who was already recovering his spiritual power.
"Old fellow, you are fast. Take my Sect Master's token and return to the sect. Bring back all the seeds of the Big and Small Azure Sky Willow trees, as well as the seeds of the Jade Mist Pure Water Lotus.
Also, pass on the news of the demon invasion to the Immortal and Buddhist sects."
"Yes!"
Zhuiyun Chongshan bowed, accepted Yang Hong's token, transformed into his original form—a small, nimble Zhuiyun Sparrow barely over a zhang long—and in a flash, disappeared.
A body length of just over a zhang was indeed very small for a ninth-tier Demon Emperor.
But Zhuiyun Chongshan's speed was truly astounding; he flew at a speed exceeding a million li per hour, significantly faster than Yang Hong's eighth-tier flying artifact, the "Sky Piercer Shuttle."
Although extreme speed could not be sustained, maintaining a speed of several hundred thousand li per hour was effortless, allowing him to easily cover two million li in a day.
If Yang Hong had enough ninth-tier Big Azure Sky Willows and enough Azure Nether Stones to activate the formations, he would have wanted to use the "Azure Nether Sky Splitting Formation" again.
This was because all records indicated that demons were a race that only knew destruction, destruction of everything!
They invaded world after world, plundering and destroying the resources of entire worlds with abandon to enhance themselves, never engaging in management or construction.
Once the resources of a world were depleted, they would abandon that world and seek out another, continuing their cycle of destruction and plunder.
All worlds invaded by demons were left devastated, with all life extinguished, spiritual items depleted, and even spiritual energy completely severed!
They had to stop the demon invasion of this world at all costs!
Although he was a transmigrator and did not have a deep sense of belonging to this world, this world held many of his attachments: his disciples, the Great Sui Yang family, and his six wives who had recently ascended to the Upper Realm.
And Li Xuefeng and Mu Xiuhui, whose whereabouts were unknown.
With these thoughts in mind, Yang Hong instructed Gu Boji to continue overseeing the work within the "Yin-Yang Taiji Formation," which involved killing demonic creatures. He himself reactivated the formation and went outside.
His divine sense spread out, and countless spiritual plant seeds were scattered. Guided by his divine sense, they precisely landed in their designated locations.
He glanced at the rising golden sun, rapidly formed hand seals, and emanated the rules of creation, merging them into the spell. Gentle purple spiritual energy drifted down from the sky, nurturing the newly planted seeds.
A hint of green emerged from the gray desert.
This time, Yang Hong did not dare to use the rules of time again. If he accidentally triggered karma fire and reignited the demonic energy within the nearby formations, the consequences would be unpredictable.
He had to be cautious.
The Radiant Sun Creation Technique continued until sunset. When the moon rose, he directly switched to the Moon Essence Jade Dew.
When the sun rose again, Yang Hong concluded this casting.
"Given the limitations of the terrain and environment, I can only shrink the 'Seven Star Gathering Spirit Formation' and plant several more.
I hope the spiritual energy provided by these nine formations will be sufficient for the 'Yin-Yang Taiji Formation' to continue improving."
After planting the external spiritual plant formations, Yang Hong returned to the "Taiji Formation."
"Gu Boji, has the teleportation gate shown any anomalies?"
Upon entering, Yang Hong instantly teleported to the bottom of the sinkhole.
"Reporting to Sect Master, there are no anomalies. The demons on the other side seem to know they cannot break through all at once, so they are only sending these weaklings to their deaths.
"Mm~ This is to be expected. We anticipate a protracted war with the demons."
Yang Hong was not surprised by this, and the others had also come to understand it.
Therefore, after a pause, Yang Hong spoke again:
"Disperse for now and kill the emerging demons from afar with your divine sense. I will set up a 'Five Directions Five Elements Thunder Great Formation'."
"Yes!"
Upon hearing that the Sect Master was going to set up a formation, the disciples of Qingfeng Mountain Villa immediately dispersed, but stayed within a reasonable distance.
Everyone knew that the Sect Master's greatest strength was not his cultivation or his spiritual plant techniques, but his mastery of formations. Observing the Sect Master's formation setup would undoubtedly allow them to gain some insights.
A large quantity of five-element spiritual materials was dispersed under Yang Hong's control. He was not someone who could not set up formations without spiritual plants; his mastery of formations was a solid seventh-tier upper-grade. He could even use inconspicuous small stones to set up formations.
Dismissing the disciples who were killing demonic creatures, 4050 pieces of sixth-grade spiritual ore, Thunderstone, were placed in five directions. The "Wooden Thunder Formation," "Fire Thunder Formation," "Earth Thunder Formation," "Metal Thunder Formation," and "Water Thunder Formation"—the five elements thunder formations were instantly completed.
Although these were not the creation rules or time rules that Yang Hong excelled at, he had comprehended the fundamental dao rhymes of the five elements. Five seventh-tier formations were not a problem for him.
As the formations were completed, whenever a demonic creature appeared, five bolts of lightning would strike simultaneously, instantly turning the emerging creature into ashes.
Next, they only had to wait for the seeds of the Jade Mist Pure Water Lotus to arrive. Once this 3000-li area was transformed into a lake, the demon teleportation gate would be completely controlled.
However, had there been any demonic activity in other regions of the Taiyuan Continent?
