After the night, it turned out that Yu Xi's concern about the bed last night was a complete waste of energy, because she had forgotten that she always had half of it on the dark dust.

Taking advantage of the time before departure, Yu Xi finally figured out the real destination of their trip, and when this place came out of the twitter's mouth, Yu Xi was overjoyed.

She didn't expect that Shen Youchen would be willing to take her with her to the place where he was so avoided, Moissanshan.

In the hearts of many Heavenly Demon Clansmen, Mount Moisang is the place where one dark age ends, but at the same time, it is also the place where another era begins.

Back then, the old demon king Jiao Aotian gathered soldiers and horses in the Heavenly Demon Clan, openly made enemies of the Heavenly Realm, and provoked hundreds of years of war, causing the entire Heavenly Demon Clan to be scorched and the people to live in poverty, and finally was sealed by the Emperor of Heaven in the depths of Moisan Mountain.

Later, when the dark dust dominated the Heavenly Demon Realm, Jiao Aotian's old department used the seal of the Heavenly Emperor as a shield to hide in Moisan Mountain, but in the end it was still surrounded and suppressed by the dark dust, and the battle of Mozan Mountain became the last battle to unify the world.

How could Yu Xi not be interested in such a place?

Coupled with the entire Heavenly Demon Realm, Moisan Mountain was the only place where beast crystals were produced, and she was already eager to try it when she thought that she would be able to get hot multicolored crystals when the time came.

In other words, she also inquired with the palace maids after returning to the palace to find out why Yin Youchen was so wary of others mentioning Moisan Mountain in front of Yu Xi at that time, which really had something to do with the beast crystal.

It turned out that all the subordinates of the old demon king were cowering in the depths of Moisan Mountain, and if the dark dust led people to attack hard, not only would they suffer heavy casualties, but even more fatally, it was very likely to hurt the seal of the Heavenly Emperor.

Once there is a crack in the seal and Jiao Aotian escapes from Mosanshan, the Heavenly Demon Realm, which has been calmed down with great difficulty, will inevitably be involved in a new power struggle, which is definitely not what Yin Youchen wants to see.

However, if those former demon kings and the old department were allowed to develop wantonly in Moisan Mountain, it would bring lingering hidden dangers to the new dynasty, and under the dilemma, the dark dust and Du Qianxing at that time made a somewhat gloomy decision together.

That is to poison the water of the Moissansangs, and it is not an ordinary poison.

In the Heavenly Demon Realm, there is a poison called Immortal Crystal Water, after drinking, although it is not harmful to life, but the Inner Dan in the Sea of Consciousness will slowly form crystals, and the Inner Dan that forms crystals cannot operate at all, and the old skills of the Demon King trapped in the deep mountains have plummeted.

And the army of the Dark Dust has finally won the final victory.

It's just that they didn't expect at the time that this poison had an extremely strong side effect.

Since the immortal crystal water polluted the water source of Moisan Mountain in large quantities, it has caused a large number of animals in the mountain forest that originally had no spiritual sense to grow crystals that can store energy.

But on the contrary, although these energy crystals made the Heavenly Demon Clan weak, they made those beasts extremely fierce, and many varieties even evolved special abilities related to instinct, becoming extremely dangerous existences in Moisan Mountain and even the Heavenly Demon Realm.

Fortunately, this change only existed around Mount Moissan, which has since become a forbidden mountain.

At that time, after Yu Xi knew all this, he only felt stunned, that immortal crystal water felt like a biochemical weapon dropped on Mount Moisang, so when they entered the realm of Mount Moissan, was it like playing Resident Evil?

Sitting in the carriage, after leaving the town, Yu Xi could feel that the speed of the convoy had increased significantly, and it seemed that this time it was going directly to the direction of Moisan Mountain.

Yu Xi felt that Dark Dust's decision to go to Moisan Mountain this time should have something to do with her experience of being auctioned off last time, the spar that could only be used in the auction was related to Moissan, and the shopkeeper later wanted to transport the spar back to Moisan Mountain, which made it not difficult to think that there must be a certain organization that had taken root in the forbidden land of the Heavenly Demon Realm, and was even expanding.

She also asked Shadow Dust face to face, did she go to Moisan Mountain this time to check on that organization, Shadow Dust just glanced at her lazily, and responded to her in a tone full of temptation, "What, you don't want to take revenge?"

If she wants to go, of course she wants to go!

She thinks that the organization is very evil, and if it can be served in one pot this time, it may be a good story to eliminate harm for the people.

"Dark Dust," Yu Xi, who was sitting in the carriage, suddenly thought of a question, "You said that the water sources in Moisan Mountain are polluted, so shouldn't we bring clean water sources this time?"

Shen Youchen opened his originally slightly closed eyes, and his inky eyes brought a slight smile, he pulled Yu Xi and nodded, "That's a good question." ”

What's good, Yu Xi found a comfortable position to lean on in the arms of the dark dust, but she quietly rolled her eyes on her little face, and when the dark dust traveled, she was clearly empty-handed, when she didn't know?

"Don't tease me, say, how to solve the water source problem?" Yu Xi pulled the arm of the dark dust, and made a gesture to bite it, in order to "threaten" the other party.

Yu Xi's little strength, Shen Youchen didn't pay attention to it at all, but he took advantage of the situation to circle Yu Xi tighter in his arms.

When he encircled and suppressed the old department of the Demon King, he didn't expect the power of the fairy crystal water to be so huge, after they found out that the creatures of Moisang Mountain had changed, he had been sending people to pay attention to the movements of Moisang Mountain, and he had also been looking for a way to crack the toxicity of the fairy crystal water.

In the past few hundred years, there is not much left of the fairy crystal water in the water source of Moissan, and the people he sent have even found some untouched cubs in the forest, and strangely, these cubs are almost all water animals, which caught his attention.

After careful consideration and thousands of attempts, he finally found a way to solve the influence of the Immortal Crystal Water, otherwise he would not have brought Yu Xi to such a dangerous place.
