As for the third floor of the Chaos Altar, it is the palace of the lord of the ancient city of Chaos.

The Purgatory Dragon Emperor usually rests and practices here.

Of course, while cultivating, the Purgatory Dragon Sovereign was also guarding the house for the lord of the city to protect the lord’s safety.

Maybe some people think...

The area with a diameter of 100 meters is divided into three thousand secret rooms, which is too narrow, right?

But in fact, the walls on the second floor of the Altar of Chaos are engraved with space expansion runes.

The entire second floor space has been expanded hundreds of times.

It was originally 100 meters in diameter, but now it's 10,000 meters in diameter!

That is an area ten kilometers in diameter...

Within the entire second floor space, there is basically a small city.

At most, it can accommodate more than 100,000 people without feeling crowded.

Three thousand secret rooms are evenly distributed in various locations in this city.

However, those who are qualified to live in this area are Zhu Hengyu's henchmen.

Those who are waiting, let alone living here.

Even if you want to come here to take a look, I am afraid you are not qualified.

As for the third floor of the Chaos Altar...

Not to mention...

Although it has not been expanded by spatial runes, an area with a diameter of hundreds of meters is as big as an arena.

In such a large area, only Zhu Hengyu lived alone, and it was already empty.

In the whole area, there are gardens, rockery, swimming pool...

Of course, a magnificent palace is also essential.

If you live alone, this place is too big.

All the way to the third floor of the Chaos Altar.

Zhu Hengyu immediately placed the Xuantian Dharma Body in the three-story palace of the Chaos Altar.

Above the core hub of the Altar of Chaos...

Xuantian Law Body was not idle either.

For the first time, the passage to the world of Xuantian was opened.

The entrance of the passage is shrouded in the core area of ​​the chaos altar.

I saw that the chaotic air in the 72 earth veins was like 72 rivers.

A wave of chaotic air was sent into the mysterious world, and into the vortex eyes of the chaotic vortex.

Boom boom boom...

Amid the violent roar, there was a huge amount of chaos.

The chaotic vortex gradually uttered a deafening roar.

Frowned...

Zhu Hengyu drove the Xuantian world, and the broken dust on the ground covered the chaotic vortex.

With a lot of collapsed sand and dust sprinkled.

The roar of the chaotic vortex gradually weakened.

However, if you listen carefully, you can still hear a faint roar.

After everything settled...

Zhu Hengyu withdrew from the world of Xuantian.

So far...

Within the seventy-two purgatory towns in the underground world.

On top of the seventy-two chaos altars, there will be no more chaotic crystals.

The chaotic air in the seventy-two earth veins was sent here and poured into the mysterious world.

On average, every day, it can provide hundreds of millions of units of Chaos Qi to the mysterious world.

From this moment...

The development of Xuantian World has officially entered the fast lane!

But because of this...

Zhu Hengyu could no longer wander around with the Xuantian Law Body anytime and anywhere.

From this moment...

The Xuantian Law Body can only sit here, madly drawing on the power of the underground world to grow the Xuantian world.

With Xuantian Dharma body sitting on the core altar.

Under Zhu Hengyu's operation...

Through these chaotic altars, it is no longer possible to return to the reversed Five Elements Realm.

Through the chaos altar in the seventy-two purgatory towns, you can only return to the chaos altar in the ancient city of purgatory.

Returning to the function of reversing the Five Elements Realm, it was sealed by Zhu Hengyu.

Without Zhu Hengyu's approval...

No one can enter or leave the underground world at will.

Even the three thousand purgatory guards are no exception...

After Zhu Hengyu's series of operations.

The entire underground world was completely divided.

Become a world exclusive to Zhu Hengyu.

No one can enter or leave without Zhu Hengyu's consent.

However, it is impossible not to let people in.

After all, these 30,000 Chuanshan miners alone are not enough to build such a vast underground world.

So next...

Zhu Hengyu will be a rising star of the Golden Eagle family.

Driving the clone of the Golden Eagle Demon Saint, heading to the city of the demon race.

See if you can recruit more races suitable for living and working in the dungeon.

Before leaving...

Zhu Hengyu will also make proper arrangements for these 30,000 Chuanshan miners.

Next, they must travel to the underground world, around 72 small towns.

To explore the location and reserves of various metal ores.

Later, various ores will be mined and transported back to the ancient city of Purgatory for smelting.

Various metals smelted...

Part of it is used for external sales in exchange for the resources Zhu Hengyu needs.

The other part can be sent into the mysterious world.

Build a small world suitable for living creatures.

After all, as a world.

Can't, there is no living thing, right?

The law of life is also one of the most important laws in the world.

Without this law, no matter what, it won't be a big world.

The Xuantian world is completely different from the normal Great Thousand World.

The world of Xuantian is a world dominated by destruction.

The whole world is filled with the power of destruction and the air of killing.

To accumulate and brew more direct destructive power and killing energy, a lot of Five Elements Metal is inevitably needed.

Only gold and iron is the best medium for condensing and brewing killing air.

Gengjin in the West is the main killer...

In the underground world, all kinds of metal ores are scattered everywhere.

Seventy-two purgatory towns are evenly distributed in various locations in the underground world.

Starting from seventy-two purgatory towns...

With seventy-two ground veins as the core!

Condensed a total of 72 metal veins.

Once all the metal ores contained in these 72-day veins are mined and smelted.

Then, Zhu Hengyu could build a planet with a diameter of more than 30 million kilometers in the world of Xuantian that could accommodate trillions of demons.

Of course, it is obviously impossible to dig out all these 72 veins.

As a result, mining efficiency was too low with only 30,000 Chuanshan miners.

Secondly, even if the purgatory furnace continues to smelt, the output is ultimately limited.

Three, the 72 veins are not dead, but alive!

As the seventy-two ground veins continue to condense and flow continuously.

Those seventy-two mineral veins are growing every day.

The total reserves of 72 mineral veins are increasing rapidly every day.

In the next few years...

Zhu Hengyu did not leave the underground world.

Even the ancient city of Purgatory has never left.

Sitting in the ancient city of Purgatory, Zhu Hengyu constantly dispatched and arranged 30,000 Chuanshan miners.

However, the strength of the 30,000 Chuanshan miners alone is too weak.

Although every Chuanshan miner can mine tens of thousands of tons of metal ore every day.

However, the 30,000 Chuanshan miners only mined about 300 million tons of metal ore in a day.

If this is to build a battleship or a city, perhaps the efficiency is still acceptable.

But what Zhu Hengyu wants to build is an entire planet!

Such a mining efficiency completely fails to meet Zhu Hengyu's requirements.

Fortunately, Zhu Hengyu's requirements are not high for the time being.

What he wants to improve is only structure and system.

After the structure and system are established and sound, he will rush to the monster clan to dig corners. See if you can recruit more Chuanshan miners.
