When Tian Xiuyun was flipping through the information in the library every day, Xuanyuan Wenchen and Mo Yilin also had a tacit understanding and did not bother, Mo Yilin knew what Tian Xiuyun was going to do, and when he was done with the business, he would also go to find the information to help. 『→お℃．．

And Xuanyuan Wenchen is much simpler here, but he didn't think of how to make Tian Xiuyun accept him for a while, so he didn't move for the time being.

After checking the information and literature for nearly half a month, and going out to listen to various gossip every once in a while, Tian Xiuyun basically understood the situation on Wuyuntian's side, and the biggest gain was the legend of the demon world.

It is not an exaggeration to say that it is a legend, the Demon Realm has disappeared in the Huan Realm for at least 10,000 years, and the time of the Ancient War has long been impossible to speculate, probably when the Heavens of Innocence began to form, and the Demon Realm will disappear at about when.

Legend has it that there are a total of eighteen demon tribes in the demon world, and the appearance of the demons of each tribe is different, but the only similarity between these demons is that they are physically strong, and the life span of the demons is unlimited, even if they are seriously injured, they will recover quickly, to put it bluntly, the demons are immortal.

So in the ancient war, in order to be able to destroy the demons, it really took the opponent's brainpower, and later someone found a weakness of the demons, that is, there is a magic pill in the head of the demons, once the demon pill is destroyed, then the regeneration ability of the demons will disappear, and the demons at that time will be vulnerable.

However, with the strong physique and innate strength of the demon clan, it was not easy to take the demon pill from their heads, and it was precisely because of the difficulty of the demon clan that the war lasted for a long time.

And the demons who have an immortal body have another very big shortcoming, that is, they don't have a primordial god, so the growth of the demon race is particularly slow, and the intelligence is incomparable with the human race and the demon race, so after the ancient war, the demon race became the biggest loser, and it completely disappeared in the world.

It has been rumored in the outside world that the Demon Realm is in the Heavens of Nothingness, and there is still a basis for this news, that is, someone once strayed into the corner of the Heaven of Nothingness and brought back the specialty of the Demon Realm from it, the Star Demon Grass.

Star Demon Grass has been one of the best elixirs for refining the body since ancient times, but after it disappeared from the Demon Realm, the Star Demon Grass also disappeared, and the Star Demon Grass that was accidentally taken out of the Heavenless Heaven was also sold at a high price.

It's just that where did this Star Demon Grass come from, and whether it was brought back from the Demon Realm, these are impossible to explain, and the person who brought out the Star Demon Grass died not long after he walked out of the Heavenless Heaven, and his death was extremely miserable.

When Mo Yilin took the time to come to Tian Xiuyun again, she had just finished sorting out and analyzing the information about the Star Demon Grass back then, and she was also thinking about whether it was time to explore the depths of the Innocent Heaven.

"How's the progress going?" Mo Yilin was still like the previous times, and the first thing he asked was Tian Xiuyun's progress.

"I'm almost certain that the Demon Realm is somewhere in the Heavens, so I'm going to find a time to go in once. Tian Xiuyun handed Mo Yilin a copy of the information she had sorted out.

And what Tian Xiuyun said about going in once means entering the real Wufu Heaven, although the place where they are now is also called Wu Delusion Heaven, but it only belongs to the periphery of Wu Delusion, and it is also a safe city specially built on the periphery.

The real Wuyu Heaven is full of all kinds of evil spirits, and those evil spirits have strong malice towards everyone who is close to the Wufu Heaven, and with the development of tens of thousands of years, there have been many evil spirits who have spiritual intelligence, and those evil spirits with spiritual wisdom are also trying to break through the barrier of the Wufu Heaven step by step, so there will be a Huanjie Alliance stationed here for a long time.

"Recently, there have always been a small number of evil spirits attacking the border, it is estimated that there will be a vicious battle to fight in the near future, it is not a wise move for you to enter the Wuwu Heaven at this time, it is best to wait for the border to calm down before making plans. Mo Yilin frowned and analyzed the recent border intelligence for Tian Xiuyun, many of these things were unknown to Tian Xiuyun.

"But when will it be, I have heard that evil spirits come without warning or planning. Tian Xiuyun also knew that this was not the best time to travel, but she still wanted to try.

"In the past, the evil spirits may have been randomly formed, but this time I read the report sent back from the front, and I think this time the evil spirits are planning to attack, and you also know that the higher the level of evil spirits, they are not only powerful, but also have extremely high intelligence, so I want you to wait for the time being. Mo Yilin unreservedly informed Tian Xiuyun of the inside news of the Netherworld, and he didn't want her to encounter an accident in her rash action.

"Could it be that something happened in the Heavens of Nothingness, otherwise how could these evil spirits be so abnormal?" Tian Xiuyun also learned about the evil spirits in the Heaven of Nothingness in these days.

These evil spirits are divided into six levels according to their strength, and each level is divided into three levels: upper, middle and lower, and the lowest level of evil spirits is the sixth level of evil spirits, and their strength is equivalent to the foundation building period of human cultivation.

And the highest-level first-class evil spirits have a cultivation equivalent to the Mahayana period, but these evil spirits are originally condensed by resentful souls, and they are not even ghost cultivators, even if they already have wisdom, they can only stay in the Heavenless Heaven for the rest of their lives, and there is no chance to break through again.

"It's also possible that we have sent spies to investigate, and I believe that new news will come soon, so I am here today to tell you, don't rush into the heavens of innocence first, everything is unknown now, no matter what, you should plan carefully and act carefully. Mo Yilin knew how eager Tian Xiuyun was to find the demon world, but she also knew that she was not a person who did not listen to persuasion.

"Well, I understand, with my current ability, I am definitely not suitable for messing around, don't worry. Tian Xiuyun knew that Mo Yilin's consideration was right, so she didn't continue to insist on entering the heavens now.

However, Tian Xiuyun had already planned in her heart, and when Xuanyuan Wenchen came back from her busy work, she wanted to apply to follow the army to meet the evil spirits for a while, and she always had to understand the attack methods and characteristics of these evil spirits, so as to prepare for the rest of the matter.

As for why he didn't make this request directly to Mo Yilin, he also felt that when Mo Yilin first arrived here, there must be a bunch of things waiting for him to deal with in the station of the Netherworld, so he didn't want to trouble the other party with such a trivial matter.

On the side of Xuanyuan Wenchen, as the dragon god of war who has been stationed here for a long time, the station here is almost his Yiyantang, anyway, she has been able to understand it very much these days, so she decided to follow the dragon clan to participate in the fight against evil spirits.

Fortunately, Mo Yilin didn't know Tian Xiuyun's plan, otherwise he would definitely refute loudly, although he was not as experienced as Xuanyuan Wenchen, but arranging one or two people to enter the team to participate in the battle is not too troublesome at all, and as a young palace master, this right is still there.
