The gods of the divine realm arrived at Tian Sheng Mountain three days before the seal was broken. Perhaps because they wanted to make a good impression and secure a spot in the first batch of volunteer teachers, they abandoned their usual lazy attitude and became incredibly enthusiastic. There were over a thousand true gods who came.

Youyou didn't waste any time, dividing everyone into three groups. The Phoenix Clan and the people of the Divine Realm were responsible for guarding Tian Sheng Mountain so that they could eliminate the demons who rushed out of the Demon Realm as soon as the seal was broken. The immortals of the Immortal Realm retreated to the outside of Tian Sheng Mountain to pursue the remaining wounded demons who had escaped. As for the disciples of the various immortal sects, they were responsible for purifying the demonic energy a hundred miles away to prevent it from spreading to various parts of the mortal world.

Theoretically speaking, even if the Demon Realm were to open, this lineup would be sufficient to hold off the demons. Only after everything was arranged did they officially begin the process of resealing the Demon Realm.

You You glanced at the tranquil Tian Sheng Mountain, took a deep breath, looked at the people around her who were on high alert, and then walked forward. The first step was naturally to break the current seal, and almost instantly a method to unseal it came to mind.

She closed her eyes and released her divine sense to carefully sense Tian Sheng Mountain. Perhaps because of the inheritance of a saint, it responded almost instantly. The entire sealing array diagram immediately appeared.

This was the first time Youyou had ever seen a complete seal, unlike the simple formations she had seen in the cave. The seal before her was enormous and complex, almost covering the entire mountain range, like a giant net covering it. The layers upon layers of intricate formations acted like the most exquisite mechanisms, firmly sealing something away.

This was the first time she had ever seen such a complex formation. Although she was used to seeing the multiple formations set up by her father, none of them were as awe-inspiring as this. She sensed it for a while, then immediately calmed down and began to search for the various formation points according to the sealing method passed down in the inheritance.

Upon closer inspection, it became clear that the seemingly exquisite and flawless formation had actually lost its divine power. In many places, it had faded to the point that it seemed about to break and fail, especially at several key points of the formation, where faint black demonic energy could be seen emerging. Although it was small, it was not hard to tell that the seal could not hold on for much longer.

Without hesitation, Youyou mobilized the energy around her and headed towards each of the array's key points, simultaneously triggering the entire array. A series of crisp cracking sounds could be faintly heard, as if something had been opened, and the original net-like seal began to dim one after another.

"The seal is broken, get ready!" Feng Rong reminded them from the side, and everyone turned their heads at once, looking warily in the direction of Tian Sheng Mountain.

As one formation after another went dark, until they disappeared completely, there was a moment of silence all around.

Sudden……

A sudden tremor shook the earth, and a massive amount of demonic energy shot into the sky. The once towering Tian Sheng Mountain began to crack with a series of rumbling sounds, and the ground split open inch by inch, just like a full-scale earthquake. The entire Tian Sheng Mountain visibly began to collapse. However, amidst the dust and demonic energy, a pitch-black mountain rose abruptly from the ground, growing taller and taller until it reached the sky, its entire body filled with pitch-black demonic energy.

"This is..." The gods also sensed the unexpectedly dense and powerful demonic energy emanating from the suddenly appearing demonic mountain.

“Mount Demon Ghost!” Youyou recognized it instantly. This was the same Demon Mountain that had sealed her and sent her to the Demon Realm. It seemed that the gate to the realm had been fully opened, which was why Mount Demon Ghost had appeared here. So she shouted a warning, “This is the Demon Mountain that sealed the Bone Dragon. Everyone be careful. I’m about to start resealing it.”

The gods' expressions grew even more serious. You You immediately took out the crystal and began setting up an array. Feng Rong and Yuan Qi also took a few steps closer to her to protect her, and they set up multiple layers of defense around her to dispel the surging demonic energy. Once the seal began, it could not be interrupted; otherwise, not only would it fail, but You You might also suffer a backlash.

With a mere thought, You You caused the entire crystal to rise into the air, wisps of pure white energy surging forth from within. You You guided that energy to begin inscribing a sealing array, an extremely energy-consuming task, especially given the surrounding demonic energy and the exceptionally complex nature of the sealing array. She could only try her best to shield herself from everything around her and concentrate on inscribing the array.

At first, things went well. After all, the Demon Realm had just opened, and they had chosen a good time. Although there was a lot of demonic energy, it was clear that the demons on that side hadn't reacted yet, so her formation went smoothly. But soon they noticed the anomaly, and demons slowly began to arrive.

"Gate...gate...the boundary gate is open!" Sure enough, less than a quarter of an hour later, a joyful voice rang out from the other side, and a large number of demons ran happily toward the boundary gate.

"Stop them! We can't let a single demon enter the Three Realms!" Yu Hao shouted, charging ahead as the first to do so. The gods and phoenixes followed suit, clearing out the excited demons who had rushed in.

The demons who first discovered the opening of the boundary gate were limited in number, and most of them were not high-ranking demons. In addition, there were many gods on their side, so they dealt with it quite easily. However, the longer it went on, the weaker this advantage would become, because there would always be a few demons who, unable to break through, would flee back to the demon realm and then bring the news to more demons. As a result, more and more demons gathered towards the boundary gate, and even city lord-level celestial demons appeared.

Originally, Yu Hao and a few other gods could handle it, but as the number of demons increased, almost all the true gods and gods joined the fray, and in less than half an hour, a full-scale melee had begun.

Youyou had tried her best to ignore the noise around her and focused on setting up the sealing array, but she was still inevitably affected. A sense of anxiety and irritability rose in her heart, and she felt an urge to draw her sword. Compared to sealing, she was indeed better at fighting head-on!

"Calm down!" Suddenly, a weight was placed on her shoulder, and Yuan Qi's gentle voice rang out, "Xiao You, focus on sensing the power within the crystal. Don't be affected by the demonic energy. Don't worry, you can do it."

Youyou's mind cleared instantly, and he felt a sense of relief. His previously agitated mood calmed down in an instant, and he immediately focused his attention on drawing the array. The complex array diagram in the air became more and more complete, and it was spreading towards the towering Demon Nether Mountain.

However, as the formation grew higher, her situation quickly attracted the attention of the demons.

"Hey, that person is setting up an array!" A demon suddenly shouted, and instantly all eyes turned towards her. Some lower-level demons were still confused, but the higher-level celestial demons immediately saw the problem.

"Whatever it is, quick! Stop her!" The demons, who had originally only wanted to break out of the demon realm, immediately changed direction and attacked her.

"..."

groove!
