Even Su Lingfeng was extremely solemn. The sea was completely covered with black fog, and the entire sea appeared black.

The situation in the Sifang Sea is definitely not any less serious than that in the Beichen Realm.

Above the four seas, there is a ban that suppresses the black fog.

Su Lingfeng secretly guessed in his heart that this four-sided sea might be the legendary holy ruins, where the legendary ancestor saint suppressed the great demon.

This restriction should be the sealing method left by the ancestor.

However, as time went by, the restrictions on the Four Seas had become increasingly weak.

"Look there!"

A saint pointed in one direction of the Four Seas and said.

The restrictions there were already extremely weak, and there was still a lot of black fog trying to get out, as if it was about to come out at any time.

"This may be the source of the black fog."

A saint speculated.

"It is indeed possible!"

The other saints also nodded in agreement.

"Oh no, take this method away!"

Su Lingfeng looked at the Dragon Bone Saint and said.

"T!"

The Dragon Bone Saint nodded and put away the Soul Mirror.

After the Soul Mirror was put away, Su Lingfeng and all the saints in the secret realm appeared in the secret realm again.

But everyone at this moment had a solemn expression on their faces.

The scene they saw was similar to what happened many years ago, and the situation now was definitely more dangerous.

At this time, all the saints were waiting for Su Lingfeng to speak.

After hesitating for a moment, Su Lingfeng said, "Next, I will select the four strongest saints. When the Origin Holy Realm is opened, they will enter the Origin Holy Realm with me to improve their strength. However, the saints who enter the Origin Holy Realm will need to stand with me on the front line to fight against the black fog in the future."

Hearing what Su Lingfeng said, all the saints looked up, waiting for Su Lingfeng's next words.

Su Lingfeng looked around and said, "Xuanyuan Sword Saint, Yinhong Saint, Fengluan Saint, Purple Saint, the four of you will enter the Origin Saint Realm with me."

Xuanyuan Sword Saint and Yinhong Saint are the strongest saints in the north except Su Lingfeng.

Saint Fengluan and Saint Ziyi were also ranked second and third saints when they were in the south.

Although the other saints felt a little disappointed when Su Lingfeng chose these four, they had no objection because they were so strong.

"Do you have any objections?"

Su Lingfeng looked at the other saints and asked.

"We have no objection and will obey the orders of the Holy Lord!"

All the saints responded.

Seeing that all the saints had no objections, Su Lingfeng stood up, looked at Saint Yinhong and asked, "How long will it take for the Origin Holy Land to open? It should be soon!"

"There are shadows of the sun and the moon above the Origin Holy Land. The shadows of the sun and the moon will begin to merge from the moment the Origin Holy Land appears. When the sun and the moon are completely merged, it will be time to open. Now the sun and the moon in the Origin Holy Land are about to merge. It will be open in at most half a month."

Saint Yinhong thought for a while and then spoke.

"I know!"

Su Lingfeng nodded, then looked at the saints and said, "During the past half month, you have worked hard to select entrants from other realms to enter together. When we return from the Origin Saint Realm, we will fully deal with the danger of the black fog."

"However, during the time when we enter the Origin Holy Land, the others must not slack off and must be careful and alert."

Su Lingfeng looked at the other saints and gave instructions.
