Sister's training method is not scientific

After some urgent persuasion, all the demon gods agreed on the surface and put aside their personal grudges first.

But then...

Some members of the Red Tail Demon Clan suddenly disappeared mysteriously.

The Red Tail Demon God was furious and went to the Abyss Demon God on the spot. The other demon gods persuaded him again.

Then.

The Devouring Demon God and the Purple Lightning Demon God secretly sent an armored guard to break into the Nine Heavens Nether Demon Realm, bombed the central island, and then left.

The Nine Heavens Nether Demon God was also furious. This action seemed to be carried out by the armored guards, but in fact, the Devouring Demon God and the Purple Lightning Demon God assisted from the side. Otherwise, how could those armored guards break into the central island?

But on the surface, the Devouring Demon God and the Purple Lightning Demon God just refused to admit it.

The Nine Heavens Nether Demon God gnashed his teeth in hatred for a while.

After that.

It was not just these few demon gods.

The ancient grudges between other demon gods were dug out one after another for some reason.

All demon gods, without exception, were caught up in this trend.

The entire Polar Night Demon Realm was undercurrent.

These demon gods said that the overall situation was important, but they were actually using various means in private.

Yun Jin received a mission to go to the Nine Heavens Demon Realm to cause trouble.

After receiving the mission, Yun Jin led her team to blow up the fortress of the collection army in the Nine Heavens Demon Realm, and all the materials stored in the fortress were destroyed.

At the same time.

The Nine Heavens Demon Realm had the same view. When Yun Jin was doing the mission, they also blew up the fortress of the collection army in the Devouring Demon Realm under the protection of the demon god's power.

For a while, both sides suffered heavy losses.

The Purple Lightning Demon God even took the opportunity to sneak into the habitat of the ancient demons, attacked them, and then retreated unscathed.

The three parties fought hard for a while.

The conflicts in other demon realms also gradually escalated, and they fell into chaos everywhere.

This chaos.

The acceleration plan stagnated for a full hundred years.

A hundred years later.

The way of heaven in the Polar Night Demon Realm appeared, forcing the eight demon gods to cease fire.

They could only suppress their anger temporarily and continue to implement the acceleration plan.

This time. The Heavenly Dao of the Polar Night Demon Realm was watching very closely. Even if they were unwilling, they could only endure and continue to cooperate.

Yun Jin was also fortunate to see the manifestation of the Heavenly Dao that time.

The Polar Night Demon Realm was indeed a first-level small world. The phantom was already the figure of a beautiful woman, and compared to Lan Lan's ignorant appearance, she was much more agile.

In the Polar Night Demon Realm, Lan Lan did not dare to show up at all.

Yun Jin specially returned to the Wushuang Sect and summoned Lan Lan to ask.

Lan Lan thought of the terrifying appearance of the Heavenly Dao in the Polar Night Demon Realm, and a trace of fear flashed in her eyes. She whispered: "The Heavenly Dao of the first-level small world is far more terrifying than you and I can imagine. If I were to show up in the Polar Night Demon Realm, I would be swallowed up by Him in an instant, and I would not have the slightest ability to resist. If I were in the Azure World, I would have the protection of the world's power. Even if the world merged, I should be able to resist for a while, but it would only be for a while... In the end, I would inevitably be completely swallowed up."

Yun Jin's pupils condensed.

The eight great demons and the ancient demons are not the biggest threats to the Azure World.

The biggest threat is the Heavenly Dao of the Polar Night Demon Realm!

The Heavenly Dao of the Polar Night Demon Realm has a series of great roads that all the demons have cultivated over the endless years.

If so many demons in the past generations have cultivated the second-level avenues, how terrible would it be if these avenues were accumulated?

So.

As soon as the Heavenly Dao got angry, the eight great demons instantly became honest. No matter how much resentment they had, they dared not show it, and could only push the acceleration plan obediently.

Yun Jin originally thought that with all the trouble they had, the Polar Night Demon Realm would be in chaos for at least hundreds of years. Unexpectedly, in just a hundred years, these undercurrents were forcibly suppressed by the Heavenly Dao.

"The Heavenly Dao of a first-level small world..."

Yun Jin couldn't help but frown.

The soul of the Immortal Emperor can only integrate the Heavenly Dao of a third-level small world at most.

The Heavenly Dao of a first-level small world is probably only something that gods can plot.

This also means that the Heavenly Dao of that kind is not something that the creatures of the small world can defeat.

She is now certain that she can face the eight great demon gods, but this Heavenly Dao...

Yun Jin thought of that figure and had no confidence at all.

"Lan Lan." Yun Jin took a deep breath and said, "You said that with the spiritual power of the fallen Immortal Emperor, the creatures in the Azure World will progress much faster than before. According to your estimate, how long will it take for the Azure World to become a second-level world?"

If the Azure World becomes a second-level world, Lan Lan will also be strengthened. Although it is still not a match for the Heavenly Dao of the Polar Night World at that time, it will always be possible to support it for a while longer.

"It will probably take hundreds of years." Lan Lan sighed.

Hundreds of years in the Azure World, in the Midnight Demon Realm, would be tens of thousands of years.

By that time, the two small worlds would have been swallowed up.

The Azure World would not have had time to become a secondary world.

"What if we add fuel to the fire?" Yun Jin's eyes flickered: "We have also collected a lot of resources in the Midnight Demon Realm. We will invest all these resources in the construction of the Azure World and further strengthen the spiritual power level of the Azure World. After that, we will carry out comprehensive improvements on the exercises, and the cultivation speed of the creatures in the Azure World should be much faster."

Lan Lan said: "It depends on how many resources there are! If the resources are sufficient, before the world merges, maybe we can break through to the second-level small world."

Yun Jin nodded.

Not maybe.

But definitely.

If Lan Lan does not upgrade to the second-level Heavenly Dao, before the first-level Heavenly Dao, there is no ability to resist at all.

Upgrading to the second-level Heavenly Dao is just one of the directions.

In addition...

Yun Jin's mind, the Yin-Yang Wheel emerged.

No matter how many second-level avenues the Heavenly Dao of the first-level small world has mastered, one thing is certain, that Heavenly Dao has never mastered the first-level avenue.

And she!

But she has the possibility of mastering the first-level avenue Yin-Yang Avenue!

As long as she controls the Yin-Yang Avenue, even if it is just a new first-level avenue, she, who becomes the master of the avenue, is enough to crush the Heavenly Dao of the first-level small world.

The Azure World is upgraded to a second-level small world.

She wants to control the Yin-Yang Avenue.

These two conditions must be met at the same time for them to win the final victory.

After discussing with Lan Lan.

Yun Jin informed everyone in the Polar Night Demon Realm of the plan to build the Azure World.

Now.

Wan Dao Ji Wu Si and Qin Ping and others have already gained some authority.

After Yun Jin gave the plan, everyone began to collect resources with all their strength.

They didn't dare to do it too obviously, for fear of attracting the attention of the Heavenly Dao. However, since the Heavenly Dao could not help but manifest after the Polar Night Demon Realm had been in chaos for a whole hundred years, it can be known that it is not so easy for the Heavenly Dao to manifest, and it is impossible for Him to monitor everything in detail.
