The old dragon

Ask New Black Lantern Castle to send a large number of transportation forces to transport back almost all the corpses left by the hive plague army in the entire Gray Wilderness.

When the driver headed by Cao Nian arrived at the Chilong Huo Valley, he looked at the piles of dead bodies of dangerous creatures, his expression so shocked that he couldn't close his mouth for a long time.

"It's no wonder that there aren't many hive disaster troops besieging New Black Lantern Castle, so they all died here?!" This was the only voice that came to the hearts of Cao Nian and others at this time.

[898.887, Expansion of the Secret Land, Arrival of the Crimson Dragons]

Su Huan and the Crimson Dragon Clan slaughtered in the Crimson Fire Valley to the extent that the Nest Disaster Army was so large.

As many as the warehouses that gather the entire New Black Lantern Fortress can't store a tenth of it.

In order to store these massive materials.

Su Huan had no choice but to return to New Black Lantern Castle immediately to expand the secret area.

The first thing he has to do now is to expand a secret place, which is specially used to store the loot he and the red dragon family have in the red dragon valley.

Of course, even without these nowhere to store loot.

Su Huan is also facing the situation of immediately expanding the secret land.

Because of him and the Crimson Dragon Clan, the Nest Disaster Army was contained in the Crimson Dragon Fire Valley.

His followers and the high-level combat power of the New Black Lantern Castle almost emptied the entire population of wild and dangerous creatures in the Gray Wilderness.

The No. [-] secret place is already full of "beasts".

A large number of groups of dangerous creatures had to be settled in the wild near the peaks.

And send the trainer to communicate, feed and appease regularly.

But the expansion of the secret place is imminent.

Su Huan is already familiar with the development and expansion of the secret land.

After all, secret places No. [-] and No. [-] were not formed naturally.

It's an acquired secret that he created by himself.

There are many ways to open up and create acquired secrets.

But there are only three methods that are most commonly used.

one.

Merge a large number of broken small secret places to form a relatively complete secret place.

Before this, Su Huan mainly used this method to open up the secret land of creation.

The disadvantage is also obvious, that is, the scale of secret places is often not large.

Even the largest Secret Ground No. [-] is only [-] square kilometers.

It simply cannot accommodate a large number of dangerous biological groups.

The advantage is that it is simple, the investment of resources is relatively small, and the required conditions are relatively simple, as long as the realization of finding the broken secret place is enough.

Even this kind of secret place is sold in Dragon Kingdom.

Second.

Taking high-level space treasures as the main core, filled with a large number of rare materials with different attributes, it gradually evolved into a secret space.

Of course, this evolution process is slow and requires artificial acceleration.

The advantage of this method is that it is easy to open up and form a relatively high-quality secret land.

The precious materials of different attributes put in will also bring different energy environments to the secret place.

For example, materials with vegetation attributes are likely to evolve into grasslands and forests.

The materials and treasures of the water system are likely to evolve into rivers, lakes, and even oceans.

Fire-type treasures may evolve into volcanoes.

Treasures of the sand system have a high probability of evolving into desert landforms.

……

The disadvantage is that it requires a lot of resources.

Moreover, there are certain variables in the environment of the finally evolved secret space.

However, the overall direction of evolution is highly likely to be controllable.

Thirdly, it is also the one that is most suitable for Su Huan at present.

It is to use the limbs left after the death of the higher race to carry out secret evolution.

Many naturally formed secret places are formed through countless years of evolution through the dead bodies of those high-level races with astonishing power, and finally formed a natural secret place.

And human beings can also artificially create secret places in this way.

However, this process was horribly slow, even the method recorded in the old Long Dian could not shorten and speed up the process to an acceptable level for Su Huan.

Even if it is accelerated to the limit, it will take several years or decades of evolution.

Naturally, Su Huan couldn't wait for decades.

The reason why he thinks this way is the most suitable for him is naturally for his reasons.

It will take a long time for the corpses of most higher races to evolve into secret places, and there may even be a certain possibility of failure in the end.

But there is a special case.

That is the higher race with space species.

Races with space species can be regarded as an active space secret place.

Using a race with space species to carry out the evolution of the secret place will also get twice the result with half the effort.

Can greatly shorten the entire evolution process.

If it is faster, it can be done in a few months, or even a month!

And this time in the war in Chilong Fire Valley.

Among the massive nest disaster creations that Su Huan harvested, there happened to be some disaster species of the space species.

As a high-ranking race, if the catastrophe species successfully evolves into a secret place, with the blessing of the space species, the size of the space will definitely not be small.
