In order to open this door, almost all the strong spare no effort, which naturally consumes a lot.

For nearly three days, the two keys seemed to have exhausted their own energy reserves, and finally disappeared slowly, while the golden vertical line was already two feet wide.

The eighteen characters are the same, dissipated in the invisible, only the golden vertical line is still present in front of everyone.

Obviously, the door of the treasure house has been opened, and it can only be opened so large.

All the strong men in the three realms did not hesitate, but flew to the golden vertical line.

The vertical golden light did not stop everyone, and everyone's body shape disappeared after touching the golden light.

Xiao Lingyu didn't compete. They didn't enter until everyone went in.

It was just when all the strong in the three worlds disappeared in the starry sky, and time passed. Less than 100 interest, the golden vertical line suddenly spread and became a golden streamer in the sky.

Beyond the golden vertical line, everyone was in a void, and in front of everyone was a completely open door with obvious outline, and the three characters "a line of heaven" were written on the lintel.

Entering this gate is a glimmer of sky.

But if you can't see anything inside the gate with the naked eye alone, your mind can't penetrate the gate.

This time, everyone didn't rush in directly, but thought about the meaning of these three words. Just relying on these three words, it was difficult to judge what happened behind the gate.

After pondering for a long time, everyone lost patience and entered the gate one after another.

The gate is not empty, but a place like a mine cave. It is very spacious. All the three strong people who enter here are lined up. If they move forward side by side, they should not touch the stone walls on both sides.

But to everyone's surprise, there was a very obvious fluctuation of divine power on the stone walls on both sides. After a careful look, we found that there seemed to be divine stones in the stone walls.

This tunnel is really a divine stone mine!

Except for a few special strong spirits like the magic spirit clan, almost all the monks moved in their hearts and stared at the stone walls on both sides without moving forward.

Those who come here are either emperor level or Zun level. Almost all monks are very jealous of divine stones. Nowadays, there are not only very few divine stone veins in the three realms, but also almost all the divine stones have been mined.

The divine stone vein here also reveals such a thick fluctuation of divine power, which proves that there must be a lot of divine stones, and they will not be too low-grade.

After a few eyes, huyunzi of the fairy world and tuobayi of the demon world took out a shovel like magic weapon and chiseled it on the stone wall.

The stone wall was not very hard. Both of them only took a few breaths to get a divine stone, so they worked harder to dig.

Seeing this, other monks also took out all kinds of sharp and hard magic weapons and joined the team of mining divine stones.

Although the divine stone is really something, Xiao Lingyu couldn't help laughing to himself when he saw that the strong men in the three worlds looked like miners.

This is the treasure house of the Heavenly Master. There must be great and better opportunities in it. It's not worth wasting time here for some divine stones.

The rich of the divine family, or the strong people with the same ideas as Xiao Lingyu, did not start mining, but continued to move forward.

What everyone didn't expect was that this divine stone mine was very long. Although there were no twists and turns, it was always a straight line, but it was like there was no end at all. Friars Xiao Lingyu and others spent half a year and were still in this divine stone mine, and there was no end at all.

However, we are careful. We are not moving fast all the time. In fact, we haven't gone too far for half a year.

This half year's time has almost wasted everyone's patience, so the strong people who didn't go mining began to accelerate gradually.

But even in the end, everyone raised the speed to the maximum, but it took a very long time and didn't fly to the end.

"There should be an end, a mine cave. How can there be no end?"

Everyone thinks so, so they still insist on going fast.

In order to reduce the consumption of the team, Xiao Lingyu invited three women and old Peng into the Shenfu, and then moved forward at full speed alone.

The speed of the venerable strong is very fast, and this mine cave does not hinder you at all, and it has always been straight. You don't need to change the direction, but Rao is so. Ten years later, you are still in this mine cave.

Because the speed is different, everyone's position is also different. Whoever is fast will naturally be in the front, and whoever is slow will naturally be left behind.

After flying for nearly 20 years, Xiao Lingyu finally stopped. He felt that there should be no end to flying like this.

"What does that mean?"

Almost all the three strong men who insist on flying to today are thinking about this problem in their hearts.

We all feel that if we want to get out of this mine, we must first understand what a line of sky means.

Unfortunately, the layout here is very simple and can not provide you with useful clues to speculate.

After all, there is still a road ahead. God knows if there is an end ahead. If there is an end, it can only be reached in a short time. Let's stop here. Isn't it a waste of time?

After all, we have only flown for decades, and decades are really nothing to us.

No one can say whether there is an end to the front end. Some friars thought that there should be an end and continued to move forward. Those who thought there was no end also began to dig mines later.

There are so many sacred stones here. If you dig for tens of thousands of years, you will gain a lot.

"A line of sky, a line of sky, but the sky is boundless... This mine cave happens to be a line, and it is estimated that most of it has no end."

Xiao Lingyu's words were recognized by the three women and Peng Lao, so everyone unanimously decided not to continue flying.

There was nothing left or right. Xiao Lingyu, together with everyone, began to mine divine stones, although he thought it was a little ridiculous.

In fact, for the respected strong, mining ore is not a hard, tired and dirty job, and the excavation speed is also very fast.

Almost every dozen breaths, Xiao Lingyu can get a piece of inferior God stone. If he really focuses on mining here, he will really reap a lot.

After a period of time, Xiao Lingyu invited chaotic animals to eat goods from the God's house. Eating goods won't use any magic weapons. They just dig with their own mouth like a pig arch mud, but they are much faster than Xiao Lingyu.

With the passage of time, Xiao Lingyu got more and more sacred stones, and they have devoted themselves to the work of mining sacred stones.

After hundreds of years, the monks who insisted on looking for the end of the mine also stopped. They still didn't find the end of the mine. They patiently spent the clean. In all kinds of helplessness, they didn't waste a good opportunity, and they all began to dig divine stones.

Some friars dig rock walls together in groups, while others dig mines alone. New caves stretch to the left or right.

This endless mine cave seems to have no end at all. Even though Xiao Lingyu's excavation speed is very fast, it is still blocked by the stone wall wrapped with many divine stones after thousands of years.

To Xiao Lingyu's surprise, the divine stone vein of such a scale should be a very high-grade vein. After digging for thousands of years, they only got hundreds of middle-grade divine stones, and none of the top-grade or top-grade divine stones. The vast majority of divine stones are lower grade divine stones.

However, Xiao Lingyu is almost certain that the divine stones contained in this divine stone vein are definitely more than all the divine stone veins in the three realms and the divine stones reserved by the monks.
