Ten thousand meters away, the ruins where Lin Yun and the others were just now are sinking into the ground at a speed visible to the naked eye.

It is as if the entire desert has now turned into a swamp, like a giant beast, devouring its own food.

"Don't look, hurry up, this underground world doesn't seem that simple." Lan Fengyuan said with lingering fear, but when he looked at Lin Yun, he found that Lin Yun had a cold face and frowned.

Before Lan Fengyuan asked, Lin Yun shouted: "Dragon and Phoenix Beast!"

As soon as these words came out, Lan Fengyuan and Dr. Biology discovered that there were only three of them here, and the dragon and phoenix beast had disappeared.

"broken!"

Lan Fengyuan's heart trembled, it must have been the sand wave that shot down the dragon and phoenix beast.

The desert swamp on the ground involved dragons and phoenix beasts.

Lin Yun's expression became a little anxious, he immediately radiated his spiritual consciousness, spreading over thousands of miles, trying to find the trace of the dragon and phoenix beast, but he was disappointed in the end.

The descending speed of this desert swamp was so fast that it was unimaginable.

Even in the ruins, there were abandoned buildings more than ten meters high, but within the blink of an eye, they disappeared completely, sinking into the ground.

Moreover, Lin Yun's divine sense was unable to explore the entire underground at all, and a hundred meters below the ground was already flooded with very strong core energy, preventing Lin Yun's divine sense from exploring.

When Lin Yun remembered his previous life, he also wondered whether the legend of the underground people was true or false.

Speaking of a hundred years ago, I am afraid that in the entire God Realm, the strongest divine consciousness ability is Lin Yun.

But even he couldn't use his spiritual knowledge to explore the ground.

Because the geological structure of God's Domain is very special, and the polar magnetic field is too strong to imagine, it can perfectly shield the perception of God's consciousness, even Lin Yun can't do the means to explore the underground world.

After a full minute, the dragon and phoenix beast did not appear, and completely disappeared. There is no doubt that the dragon and phoenix beast must have been swallowed by this desert swamp.

"Lin Yun...Sorrow..." Lan Fengyuan sighed, trying to comfort Lin Yun. In his opinion, the desert marshes are terrifying and are caused by nature. Here they are unfamiliar with their lives. There is no possibility of survival at all.

"You go first, I will stay." Lin Yun said without hesitation.

Lan Fengyuan was stunned and exclaimed: "Are you crazy? The underground people here regard humans as great enemies, and the underground king, a half-step martial emperor, is there. If you stay here and be discovered, you will die forever."

Lan Fengyuan couldn't understand it. In his opinion, the dragon and phoenix beast was nothing more than a holy beast kept in captivity by Lin Yun.

When a sacred beast died, why bother to fight so much.

"So you leave first, and then it's my own business." Lin Yun glanced at him and stopped explaining.

In the eyes of outsiders, the dragon and phoenix beasts and the two birds, the two monster beasts became a member of the Slaughter Sect, more like the relationship between the Thunder God beast and the Sanctuary Alliance.

On the surface, the Thunder God Beast is helping the Sanctuary Alliance and guarding the Sanctuary Alliance.

In fact, it was just a divine beast raised by the Sanctuary Alliance to defend against foreign enemies.

But for Lin Yun, both the dragon and phoenix beasts or the two birds had a life-long friendship with him.

Not to mention, when he was in the "God Phoenix Ancestor Land," he had already promised the Phoenix God that he would take good care of the dragon and phoenix beasts.

To see people in life, to see corpses in death!

Even if the dragon and phoenix beast died here, he would go back with the bones of the dragon and phoenix beast to give everyone an explanation.

"Lin Yun, I advise you to think carefully, this is one..."

Before Lan Fengyuan's words were finished, Lin Yun had already jumped and flew towards the depths of the underground world, no longer listening to his nonsense, leaving Lan Fengyuan and Dr. Biology looking at each other.

"Sect Master, we..." After a while, Dr. Biology spoke and asked cautiously.

Lan Fengyuan gritted his teeth and said: "I can't control that much, let him go by himself. We wait for him at the entrance for a day. If he doesn't come back one day later, I'm afraid he will die here."

After all, Lan Fengyuan and Lin Yun have not yet reached the kind of situation where they can sacrifice their lives for each other.

Being able to choose to wait here for Lin Yun for a day is already Lan Fengyuan's ability to make the biggest compromise.

At the same time, Lin Yun had already flown nearly a hundred miles away.

During the flight, Lin Yun saw many ruins of buildings.

Among the ruins of these buildings, many have disappeared.

The ruins where Lin Yun and others fought with the underground people just now were also plunged into the desert swamp.

Now the desert has returned to calm, as if the desert swamp that just broke out was just a dream.

Lin Yun felt that this was not an accidental outbreak of nature, but someone deliberately did it. He couldn't tell a reason, but he had this intuition.

Perhaps it was because the dragon and phoenix beasts had the possibility of surviving only because of man-made reasons.

Although Lin Yun's divine consciousness could not go deep into the earth, his divine consciousness was not affected much in this space now.

According to the feedback from the divine sense, a large number of underground people gathered not far in front, and it seemed that fighting broke out.

A few minutes later, Lin Yun also reached the depths of the underground world.

The place where Lin Yun and the others came just now was probably because they were on the edge of the underground world, so they were around a hundred miles away and there were not many people.

After stepping here, Lin Yun heard the screams and the sound of fighting from afar.

Although Lin Yun was worried about the safety of the dragon and phoenix beast, he still calmed down as much as possible.

After all, if what Lan Fengyuan said, this underground world Lin Yun is unfamiliar, and because of the war with humans, the underground people had to live in the underground after the defeat.

The underground people must regard mankind as a great enemy, and if they see Lin Yun, conflicts will definitely break out.

The geographical environment here has changed, and some very huge stones have begun to appear around, some of which are tens of meters high, like a small hill, sitting on the ground.

Lin Yun chose to avoid a huge rock, and then watched everything in front of him.

Tens of thousands of meters ahead, there is a village with many buildings.

Through the houses that are just piles of stones, it is not difficult to find that this place should be equivalent to a slum in God's Domain.

Now there is an army of tens of thousands of underground people who are slaughtering this village.

I saw this tens of thousands of underground people surrounded the entire village in it.

This army of underground people was obviously much more formal than the first time Lin Yun saw it. Among them, the underground people who reached the breath of Wu Zong and above were all wearing metal armors, but they only protected their chests.
