"I see!" Hearing the underworld, Chen Xuntian seemed to understand something.

"Then how can I build a small world in my world that is suitable for the survival and reproduction of my Moon Demon Clan?"

"The reason why small worlds can't give birth to soul creatures. It's because the small world lacks the wheel of life. ”

"What is the Wheel of Life?"

Ling Xuanfei said: "It's a kind of reincarnation. If you blindly pursue life without death, everything in this world is relative, there is life and death, there is yin and yang. You can also think about what the world would be like if there was only life in this world. ”

Lei Ying didn't understand, Chen Xuntian said: "The world will be overcrowded, and it will eventually become unfitting." ”

Ling Xuanfei shook his head: "It doesn't take that step yet, first of all, the law of life is dominant, encroaching on other laws, and then the law of the small world is disordered, to the big chaos, and finally the law collapses." ”

Chen Xuntian nodded, he also remembered the ecosystem he had learned in the classroom in his previous life. It's the same thing.

"I see!" Chen Xuntian asked, "Sister, what is the wheel of life?" Could it be that you're talking about the underworld? ”

Ling Xuanfei nodded: "The underworld has the power of reincarnation, which is what I call the wheel of life." Have you ever heard that there are demons in the underworld? ”

"Nope." Chen Xuntian shook his head.

Ling Xuanfei explained: "So... This is the reason why the small world can't give birth to demons, and if there are no demons in the underworld, there will be no demons in the small world. As for why the demon race was born from the void space, this question is also a mystery in the fairy world. ”

"Ling Xuanfei, what you mean is that the small world suitable for the survival of my Moon Demon Clan cannot be built." Yue Xiaolei was a little lost.

"Sister, there's no way?"

Ling Xuanfei shook his head: "No, there is." ”

"How?"

"The underworld doesn't imprison demons, and it doesn't imprison immortals." Ling Xuanfei asked, "Brother, do you know why it is difficult for the upper realm to give birth to an heir?" “

"Is it the Heavenly Rule?"

Ling Xuanfei shook his head: "No, the upper realm has established Tianfu in imitation of the lower realm, and Tianfu has mastered reincarnation, so immortals can be born, but the upper realm contains countless immortal realms, and the number is extremely large, and the resources to establish Tianfu are limited." This is the reason why it is difficult for the immortals of the upper realm to give birth to children. ”

"Sister, what do you mean... We can build a demon dungeon here. Chen Xuntian seemed to understand.

"That's right. It's much easier to build a demon in the Nether than in the Upper. ”

"Will you?"

"Understand a little bit, it's good to build a small-scale demon mansion."

"Great, so that my Moon Demon Heavenly Clan will have their own little world." Yue Xiaolei said happily,

Soon after, Chen Xuntian and Ling Xuanfei left the Moon Realm.

Chen Xuntian saw that the empress's sister seemed to have something on her mind: "Sister, what are you thinking." ”

Ling Xuanfei asked, "Brother, do you know why there are so many forces in the upper realm?" ”

"This..."Chen Xuntian shook his head.

"In order to fight, grab resources and territory and immortal positions, etc." Ling Xuanfei asked again, "Then do you know why the Upper Realm has been fighting for so long?" ”

"Isn't it for resources and territory?"

"These are just secondary." Ling Xuanfei said: "The most important thing is the intervention of some Tianfu forces. To know. If the people of the upper realm want to give birth to heirs, they must have immortals fall, so the immortal realm will fight for many years. ”

"I see." Chen Xuntian suddenly realized: "So in order to die worthily, some forces will also send immortal soldiers to attack the demon clan." ”

"You're right, how long the life span of immortals is, there are always immortals who want to have children." Ling Xuanfei said.

Chen Xuntian gritted his teeth and said: "I think this practice is very unfair, just to give birth to children, let some innocent immortal soldiers die." Do the bigwigs in the upper realm allow this kind of injustice to appear? ”

Ling Xuanfei shook his head: "Only some weak people will die, and the strong will be left behind, and after layers of selection, the upper realm will only get stronger and stronger." Then I was more sure to fight against the demons. ”

Chen Xuntian was silent.

Ling Xuanfei said: "I may establish a Demon Mansion in the Nether Realm, and the scale must not be one hundred thousandth of that of the Heavenly Mansion, and do you know what such a small Demon Mansion means?" ”

"Long years of war?"

"That's right, so... That's why I'm hesitant to build a demon mansion. ”

Chen Xuntian nodded. Secretly said: "Sure enough, the empress's sister is worthy of being the immortal emperor of the fairy world, and she knows so much." ”

"Sister, if you set the rules of the small world to make the demon race's ability to reproduce worse, maybe it will be better."

"That's all there is to it." Ling Xuanfei nodded and said, "I am going to build the Moon Realm, and so is the Demon Mansion, but I still need a lot of materials that you need to help me find." ”

"Okay."

In this way, in order to build a demon mansion, Ling Xuanfei asked Chen Xuntian to go to the demon world to find a lot of materials.

A year later, a simple demon mansion was built, and then Ling Xuanfei asked Chen Xuntian to go to the demon world to catch some demons.

Chen Xuntian infiltrated the Red Moon Demon King City, selected some Moon Demon Heavenly Clan, and sent them to the Moon Realm.

So far. The Moon Realm has been perfected. Yue Xiaolei also fully recognized Ling Xuanfei. Ling Xuanfei's cultivation was also slowly recovering in the Moon Realm.

In time, her cultivation will surpass that of the past.

Moon Boundary.

Chen Xuntian saw that Ling Xuanfei was meditating.

"Sister, what are you looking for me?"

"Brother, I've been feeling a little restless lately?"

"What's going on?"

"It's been nine years since I left the Xuantian Domain, and it is estimated that there is trouble in the Xuantian Domain."

"Xuantian Domain!"

"Brother, my strength hasn't recovered yet, you can go back for me!"

"Okay."

Soon after, Chen Xuntian left the Moon Realm.

Xuantian Domain.

Millions of Xuantian Warriors and Xuanlong Warriors were guarding inside the Dragon Emperor Pass, while outside were armies from the Tiger Qiong Heavenly Domain, the Ice Dragon Heavenly Domain, the Xuangui Heavenly Domain, and the Fire Bird Heavenly Domain.

Now. The armies of the four heavenly regions were stationed outside the pass. Their combined army numbered more than five million. It was more than five times the size of the Xuantian Domain's army. If they hadn't been able to break through the Dragon Emperor's Immortal Protection Array for a while, I'm afraid they would have already been killed.

Although the number of troops in the Xuantian Domain is smaller than that in the Four Heavens Domain, the prestige of the Xuanlong War Army and the Xuantian War Army's own Dragon Emperor is still there.

Therefore, the commander Zhu Changfeng, who was the leader, did not underestimate the enemy, and he sent a Tianjiao from the Ice Dragon Heavenly Domain to call the battle.

Tianjiao Longyang stepped forward and called out: "Xiao Yan, Pang Lin." Dare to come out and fight me. ”

Hearing this, Xiao Yan and Pang Lin glanced at each other, and then flew out of the gate at the same time.

"Long Yang, come to fight."

Long Yang was stunned for a moment, and then said, "I'm talking about one of you, not you..."

"Long Yang, I admit that you are very strong, and you may also have the possibility of defeat if the two of us face each other. But for the sake of my Dragon Emperor Pass, we must stand up, Long Yang, do it! ”

"Shameless!" Long Yang said angrily: "I'm talking about which of you two dares to fight with me, not the two of you fighting with me." ”

"Long Yang, do you mean that you are afraid of the two of us and dare not accept the challenge?"

"You..."Long Yang was angry.

"Brother Long, don't worry, how can this kind of good thing let you steal the limelight alone and take me to Tiger Roaring Mountain." A tiger-shaped big Han road. Then he flew out and stepped on the ground, and the ground suddenly burst into a large crater.

"And me, Fire Sparrow Sky Domain Vermilion Dance." A woman with a red fan in her hand flew into the air. Stepping on the fire lotus between the ground.

"Three days of the Four Heavenly Domains are gone, and my Xuangui Heavenly Domain Li Ye is naturally indispensable."

A man in a bulky armor walked out slowly. With each step he took, the ground sank.
