Han Feng quickly returned to his palace and went directly to the cultivation room to practice the soul cultivation method taught by Long Ziyun for the first time.

He conscientiously comprehended it, and gradually found that this exercise was suitable for his own cultivation, and he couldn't help but secretly rejoice.

"I've finally got a suitable soul cultivation technique!" he muttered to himself.

This exercise is called Plough Soul Technique, the name is strange, but it is very practical, after Han Feng came to his senses, he was already able to absorb special energy from the outside world to replenish his soul sea, and constantly expand his soul power storage.

What's more, he found that his seven-colored soul power was actually completely undeveloped, and after the ploughing of this technique, it differentiated into seven colors of soul power, and the soul power of each color actually glowed with more powerful power, and the overall increase was nearly one percent.

Moreover, this is just the beginning, and when he has a deeper understanding of the Ploughing Soul Technique, there may be more surprises to come.

It's no wonder that those old demons or old ghosts before attached great importance to his colorful soul body, perhaps because of these secrets hidden, he needs to dig further and will exert more majestic power.

Once Han Feng cultivated, he would fall into a state of madness, ignoring what was going on outside the window, and he would retreat for more than ten days in a row, until Long Ziyun sent him a message, and he had to stop practicing this exercise.

"Elder Han, please come to Yuntian Peak quickly, there is something important to discuss!" Long Ziyun's tone was a little hurried.

Han Feng naturally didn't dare to slack off, hurriedly washed up, and went out of the door, heading straight to Yuntian Peak.

Yuntian Peak is the peak that Ximen Holly first brought him to the Moyun Sect some time ago, and it is the place where the sect master lives and cultivates.

In a moment, Han Feng flew to this peak at a gallop.

There are still heavily guarded patrols on the platform, guarding this mountain day and night, after all, the suzerain is the head of a sect, and his safety cannot be neglected.

Seeing Han Feng coming, a team immediately came to review, but when they saw Han Feng's token, they immediately gave way, and it seemed that they had received orders in advance.

Han Feng strode forward, all the way smooth, and directly entered the Purple Cloud Palace.

Long Ziyun was waiting in the lobby early in the morning, he was sitting on the first red wooden chair, but in addition to him, there were two middle-aged men sitting on either side of the lower head, as if they were talking about something.

Long Ziyun raised his eyes and looked at Han Feng, and immediately said, "Elder Han is here, hurry up and take a seat, just waiting for you to discuss!"

The two of them also turned their heads and nodded at Han Feng.

Han Feng gave the three of them a fist salute, except for Long Ziyun, he had also seen those two, and knew their identities, they were the great elders of the Moyun Sect, and their perfect cultivation could be said to be one of the pillars of the Moyun Sect.

"I don't know what the sect master ordered me to come over?" Han Feng asked straight to the point after sitting at the bottom of the seat.

"Elder Han, before discussing the matter, let me ask you a question, do you know the way of the formation?" Long Ziyun asked without answering.

"I understand a little. Han Feng responded truthfully.

In fact, Han Feng did know the way of the formation, but compared to the way of the run, it paled in comparison, and he could only be regarded as having just entered the hall.

"That's okay, we have a set of formations here, and we need to gather nine Heavenly Rune Masters above the ninth rank to be able to cast it. Long Ziyun said.

Saying that, he didn't care whether Han Feng agreed or not, he directly took out a jade slip and threw it to Han Feng.

Han Feng was slightly stunned, but he still took it, but he didn't rush to watch, but instead looked at Long Ziyun with a puzzled look in his eyes.

"Elder Han, some time ago, the Ancestor didn't actually go to the Feather Immortal Sect, but was mobilized by the Feather Immortal Sect to go to the Death Grand Canyon to check the abnormal situation that appeared there. Long Ziyun explained.

Han Feng didn't speak out loud and continued to listen.

"There is indeed a problem, the Heaven and Earth Qi Wall of the Death Grand Canyon has expanded for thirty miles for some reason, and it is still expanding even now, but the speed is just a little slower, the space around there is distorted, completely chaotic, ordinary monks can't get close, the situation is extremely serious!" Long Ziyun said with a solemn expression.

"Now the Feather Immortal Sect has organized talismans from all over the country to go to the main vein and set up a formation to block its expansion, in case of a catastrophe!" Long Ziyun added.

Han Feng also knew a lot of secrets through Lin Xiaoyue of the Feather Immortal Sect, the Great Canyon of Death was the place of the seal left over from the Great War of the Ancients, and it was said that it was the spatial rift between the ghost realm and this realm, and it was from it that their ghost clan army rushed out and wreaked havoc on the Mighty Sword Continent.

Of course, in ancient times, not only the ghost clan entered this world, but also the demon clan took advantage of the chaos to break in, and the two clans joined forces and almost subverted the entire continent.

Although the Terran won in the end, it also suffered heavy losses, and many sects were wiped out, such as the current four major sects, which only rose after Jianyun Villa.

The most powerful sect back then should have been the Fu Sect, but in order to block the attack of the ghost clan and the demon clan, the sacrifice was great, and even the legendary strongest Fu Zu fell because of this, and the tragic situation at that time can be imagined.

At the cost of his own life, Fu Zu cast the Heaven-Sealing Technique, successfully slaying the strongest of the two clans that invaded, and at the same time sealing them with the entrance to this world, one of which was the Grand Canyon of Death.

After the death of Fu Zu, the second largest faction of Jianyun Villa organized all the monks to kill the remnants, but this is the case, and Jianyun Villa was also greatly injured because of this, almost completely destroyed, and in less than a thousand years, it was replaced by the existing four major sects.

"The ghost clan is going to break the seal again?" Han Feng's eyes flickered, and he asked slowly.

"The current situation is unclear, judging from the feedback from the Feather Immortal Sect, it shouldn't be, it may be caused by the fluctuation of the power of the interface between the ghost world and our world. Long Ziyun shook his head and continued: "However, this fluctuation may affect the seal left by the Fu Ancestor back then, so we need to take all possible measures to stop this expansion as much as possible, and at the same time provide energy for the sealed land to stabilize it, so that there will be no real rifts!"

"However, can we gather nine Nine Rank Heavenly Rune Masters in our Eastern Eight Branch?" a great elder surnamed Zhang frowned and suddenly asked.

Han Feng glanced at him sideways, his name was Zhang Yiming, he was kind and kind-eyed, and his two strands of white sideburns floated in his ears, which was particularly eye-catching.

"It doesn't matter, we have four in the Moyun Sect, two in the Hades Sect, one in the Luoyun Sect, and one in the Dongli Gang, there are eight in total, and the last one will be deployed from the Xuanqing Gate of the East Seven Branches, and there are just nine Nine Rank Heavenly Rune Masters, who can cast the Nine-Nine Heavenly Formation and can mobilize a small amount of the Origin Power of this realm to stop the expansion of the Death Grand Canyon and stabilize the seal of the Fu Ancestor. Long Ziyun explained.
