"I almost forgot about this."

Lu Changzhi said softly and shook his head.

It was a long time ago that I got the activation key.

At first, I just took out the unlocking key, and then I was told that it had worked and the relevant place would appear soon.

But now it seems that so much time has passed and there seems to be no relevant news.

"But."

With a soft hum, Lu Changzhi's face showed a thoughtful expression:

"If I remember correctly, the one related to the Sealing Key should be called the Saint's Battlefield, right?"

In addition, he vaguely remembered that the battlefield was not only about the origin of spiritual power, but also about the secret of immortality.

It’s a pity that now it’s just a picture left by my father. I can only listen but cannot communicate.

In this regard, it is quite unfriendly.

Lu Changzhi waited and listened for a while, but he didn't hear anything more. He just said that he would go there when he had the chance.

In addition, there are some other matters related to spiritual practice.

After a while, the figure disappeared.

Peace returned to the palace.

Lu Changzhi looked around and found nothing else, so he stood up and walked out.

"Grandmaster Liang."

Liang Si was waiting outside the palace. He greeted him and Lu Changzhi asked.

"Does the ancestor know anything about the Sealing Key and the Longevity Battlefield?"

Having said this, Liang Si nodded:

"The space sealed by the key has many different names. In the four directions, it is called the Saints' Battlefield. Outside, it is called the Immortal Battlefield. According to rumors, there are secrets of immortality in it, but whether it is true or not has not been confirmed yet."

"So where is this battlefield?" Lu Changzhi said:

"It is said that the changes in the original spiritual power of the four directions were related to this battlefield."

"It is indeed relevant." Liang Si nodded:

"But this battlefield is not in the four directions. Only those who hold the activation key can find the exact location of the battlefield with the help of the activation key."

After a pause, Liang Si added:

"According to the sect's information, there are two sets of unlocking keys in this world."

"Two sets?" Chief Lu was stunned.

Liang Si nodded:

"But it is not complete. Of the two sets, Kun takes one, and the others each have two. After this unique Kun appears in the world, the two related activation keys will be awakened."

"Then there will be two battlefields of immortality?" Lu Changzhi was a little surprised.

At the same time, he was also a little curious.

When he first found out there were two sets, he wanted to know which set the key he got belonged to.

I didn't expect it to be the only one.

Is this luck or something else?

"No." Liang Si shook his head:

"One is the real battlefield of immortality, and no one can know its exact location in advance. The other is right here."

"In other words, to outsiders, this is the former battlefield of immortality. The key that opens the seal is exactly the seal that exists around our four-sided land."

Lu Changzhi was silent.

Although he had anticipated the possibility of a blockade around the four directions of the land, after all, for a long time, except for the Xia tribe in the secret realm, he had not come into contact with outsiders from other places.

But the fact that the Four Directions Land is the battlefield of immortality does sound a bit magical.

At this time, Liang Si said:

"Have you ever known the Endless Sea?"

Lu Zhangzhi nodded:

"The edges of the land are surrounded by the Endless Sea. The Endless Sea is extremely vast. For countless years, no one has ever crossed this sea. However..."

As he spoke, Lu Changzhi changed the subject and said:

"If I'm not mistaken, it should be related to the ban on the unlocking key, right?"

"nice."

Liang Si nodded, "The Endless Sea is not endless. It is just called the Endless Sea because we cannot pass through it and are trapped inside it forever."

"But this seal has gradually weakened since the appearance of the seal key. The speed at which the calamity clouds that appeared a few days ago dissipated has further increased. It won't be long before it completely dissipates."

"At that time, the four directions will no longer be isolated from the world, but will be fully exposed to the world, and the related risks will also appear."

Lu Zhangzhi nodded.

He understood what the so-called risks were. If someone linked the Four Directions Land with the Changsheng Battlefield, just thinking about it would make him realize how great an impact this would have on the Four Directions Land.

"Of course, danger and opportunity coexist." Liang Si continued:

"Connecting with the outside world will also bring new opportunities, and it is not all bad for the growth of elders and disciples."

As he spoke, Liang Si handed over a jade talisman.

"There is some information about the outside world in it, you can check out Digest Digest."

Afterwards, the two chatted about some other things.

After staying with the ancestor for a while, Lu Changzhi left.

Just after returning to Yinyuan Peak, Cang Wenyu came over in a moment, with a curious look on his face, and asked:

"Changzhi, your parents, what state are they in now?"

Hearing this, Lu Changzhi looked towards Cang Wenyu, smiled slightly, and said:

"Master."

"This matter is of great importance. So, you first break through to the Saint Realm, and then I will tell you."

"Um?"

Cang Wenyu looked at Lu Changzhi with a strange expression, shaking his head repeatedly:

"Do you think everyone is like you? Breaking through the Saint Realm is as easy as eating and drinking water. Your standards are too high!"

Lu Zhangzhi laughed and said:

"Just kidding. Actually, I don't know either. I only saw the light and shadow left by my father. I don't know the specific realm, but I think it must be pretty good."

Hearing this answer, Cang Wenyu shook his head slightly:

"I have the time to give you something, but I can only communicate with you through light and shadow?"

"This," Lu Changzhi coughed lightly:

"Giving things is a special case, but it's different after all."

Cang Wenyu nodded, and did not dwell on the matter any further, but said:

"Your disciple Gu Chen ran into some trouble during his trip. Some unusual changes occurred in the Endless Sea, and he happened to encounter them."

"Near Linhai City?" Lu Changzhi raised his eyebrows and asked.

Cang Wenyu nodded:

"But fortunately, the danger has been resolved by him for the time being, and he is now on his way back."

Lu Zhangzhi nodded.

He was quite familiar with Gu Chen's sign-in system.

Basically, if an unusual check-in location suddenly appears, it is probably because something is about to happen near the check-in location.

This time, it was indeed the case.

However, even the thoughts I left behind were not triggered. Apparently, the trouble was within control.

After asking for some relevant information and chatting about other things, Cang Wenyu got up and left.

He returned to the house, sat on the meditation chair, and was about to pick up the jade talisman to examine it.

At this time, the system prompt sounded:

"Special mission has been issued, do you want to check it?"
