Guarding a reservoir? I am guarding the river of time!

The four emperors looked around at the desolate area. At a glance, they could only see the gray earth and the stone mountains.

At this time, the Bone Emperor had a bad premonition. His spiritual sense spread out. When he noticed something, his pupils shrank sharply.

"It's over. I don't know where that man sent us to..."

"There is no breath of any living creature within a radius of one billion kilometers."

Hearing this, the other three emperors also quickly opened their spiritual senses. After a careful inspection, panic appeared on their faces.

According to the normal process, they traveled to seven thousand years ago, and only needed to travel a few kilometers in the long river of time.

But after the man accelerated them, they rode in the black coffin and rushed downstream for an unknown distance. The powerful time turbulence caused them to fall into a coma. They had no idea what time and space they were sent to.

Even when their spiritual senses were fully opened, they could not feel the breath of any living creatures. . .

Did this guy travel to the time before Pangu created the world? !

Huh?

Where is the black coffin? !

At this time, the four emperors realized that the black coffin was no longer around!

"Hurry!"

"Let's search from four directions separately. Come back here in an hour!"

As soon as the words fell, the four emperors turned into streams of light and rushed towards the four directions of southeast, northwest and northeast.

An hour later, the four emperors returned to their original place empty-handed.

"I didn't find it..."

"Me too, I've searched for hundreds of millions of kilometers and couldn't find it at all."

The Bone Emperor sat down on the ground and muttered, "It's all over now. The black coffin probably fell into a certain time and space."

"We don't know where we were sent to."

"Now that the black coffin is gone, that is, the tree of time is gone, we probably can't go back..."

As soon as these words came out, the other three emperors also had black eyes and their legs were a little weak.

The black coffin was lost, and they didn't know what time and space they were in. Let alone completing the task of the master, they couldn't go back now.

． ． ． ． ．

A gust of wind blew up the waste sand on the ground. The four emperors had stiff faces and dull expressions, and had completely lost hope.

This was more uncomfortable and more desperate than trapping them in the Black Central Realm.

Trapped in the Black Central Realm, they at least knew where they were, and at least they could expect the Lord to save them.

Now, the time is wrong, and the space is wrong.

Even as strong as the Lord, it is impossible to deduce what time and space they are in, let alone find them.

The Bone Emperor, who has always been calm and composed, is now completely exhausted.

If the black coffin is not lost, they will rest and cross the long river of time again.

But now, without the most important "Wood of Time" as a medium for crossing the river, they can no longer cross the long river of time.

Things like the Wood of Time are rare in the world, and finding them depends entirely on luck.

They used to be able to cross the long river of time because they borrowed the Wood of Time from their predecessors.

In this place, let alone trees, not even a blade of grass can be seen!

If the tree of time does not exist in this world, then they will be trapped here forever until they die of old age.

． ． ． ． ．

In this way, the four emperors sat here for three days and three nights, and could not think of any solution.

"Bone Emperor, I think there is only one way. This place must be thousands or tens of thousands of years ago."

"Why don't we wait for the passage of time and live to the normal timeline?"

The Southern Emperor, who had been silent for a long time, spoke up.

As soon as this was said, the Bone Emperor smiled bitterly and said, "How can you be sure that this is thousands of years ago?"

"It's no problem to live for thousands of years. We can retreat and endure it."

"But... what if this is tens of thousands of years, hundreds of thousands of years ago, or even longer?"    "Do you think we have the life to live hundreds of thousands of years?"

"Also, how can you be sure that this world is our original world?"

"You have to think clearly. Not only is our time wrong, but our space is also wrong!"

Hearing this, the Southern Emperor fell into despair again.

Yes, if they only traveled to 7,000 years ago, even if they lost the black coffin, it would not be a big problem.

If they could survive until 7,000 years ago, they would return to the normal timeline.

But the problem now is that it is definitely not as simple as 7,000 years. They have traveled so far in the river of time, it is estimated that it is possible to travel 700,000 years.

700,000 years...

What a long time.

They are just celestial beings, not immortal kings, let alone immortal emperors, and they cannot live that long.

Even if an immortal emperor came, 700,000 years would be enough to drive any immortal emperor crazy.

This 700,000 years is still a conservative estimate.

What if it is longer?

They dare not think about it anymore, and the more they think about it, the more desperate they become.

"The only way now is to find the tree of time."

The Bone Emperor stood up and looked into the distance with a complicated expression.

"But the tree of time is rare, and this world is still barren..."

The Dark Emperor said in despair.

"This is the only way." The Huan Emperor said.

． ． ．

The Bone Emperor cut his finger and dripped a drop of his blood onto the ground.

"We'll use this place as the meeting point."

"We'll search from four different directions and meet once every hundred years."

"When the hundred years are up, whether we find it or not, we'll have to come back here."

After that, the other three emperors also cut their fingers and left their blood here as a mark.

Four blood marks appeared on the ground. These were blood marks left to prevent them from getting separated, because this world is really too big.

"If someone's blood mark disappears after a few years, it means that someone has fallen."

"If a hundred years later, when you gather here again, you find that my blood mark has disappeared, it will prove that I have fallen."

"Then, don't give up. As long as one of the four of us survives, we can leave here, go find the black coffin, and complete your mission."

The Bone Emperor warned the other three emperors word by word.

The four blood marks left behind not only represent the meeting point, but also represent whether they are still alive.

． ． ． ． ．

"Let's go."

"We don't have much time, we can't waste a minute."

After saying that, the Bone Emperor faced the north, tore apart the space in the next second, and started looking for the legendary tree of time from the north.

The other three emperors went to the east, south and west directions respectively. ． ． ．

． ． ． ．

Time flies, and hundreds of years fly by in the blink of an eye.

When the Four Emperors gathered together again, they looked much older.

In just one hundred years, the Bone Emperor had a lot of gray hair on his head. This shows how many things he has experienced in this one hundred years.

Seeing that the four of them were all empty-handed, they all understood that they had not found the Tree of Time.

The four emperors didn't say anything more, just nodded to each other, then turned around and continued looking. ． ． ．
