Mu Yu has been in Dawn Valley for four days, and Mu Yu has had a very comfortable life in the past four days, and every day Aunt Spider and others will send Qiao Xue something delicious.

The demon people in Dawn Valley are very good to Qiao Xue, just like their own daughter, Mu Yu is also stained, there is a lot of good food and drink, of course, a large part of it goes into Xiao Shuai's stomach.

Qiao Xue always locks the door when she sleeps at night, not giving Mu Yu any chance, and Qiao Xue now has to run outside the Dawn Valley every morning to cultivate, not giving Mu Yu any chance.

"It's normal for lonely men and widows to be in the same room, the weather is dry, and the guns go off!" Mu Yu muttered every time.

Then Qiao Xue glared at Mu Yu fiercely.

"Mu Yu, do you think we should go to that ruin? Ryuto yawned.

"That's right, we're thick-skinned and don't get poisoned. "Xiao Shuai is eating the pork buns he got from Aunt Spider, the food in the demon clan is good, they can eat and drink for free here.

"Don't go to the ruins. I'm as good as you can filter poison, but there's more to it than just a toxic mist. Qiao Xue said solemnly.

"Then what else?" asked Mu Yu.

"Last time, I heard Grandpa Qinglong inadvertently mention that it was an ancient battlefield, a forbidden land of the Three Heavens, and if you didn't reach the Mahayana stage, you couldn't withstand the coercion there. Qiao Xue said.

"Ancient Battlefield, for whom is it used for fighting?" Mu Yu was even more puzzled.

"Only people in the Mahayana period can go, so do you need to ask? It must be a fight for the people in the Mahayana period. Qiao Xue said.

Mu Yu felt that it was not that simple, but he didn't bother to delve into it. He still has a lot of troubles to do, and he has time to take care of some ancient battlefield.

Staying in Dawn Valley honestly, being a good boy who keeps to himself, and doesn't make trouble or cause trouble, is Mu Yu's purpose.

This purpose is actually what Mu Yu has always adhered to, since he left the Moyun Mountain Range, he has to be a quiet cultivator, but often things are always unexpected.

For example, he went to the Deadwood Valley just to find something to eat, but he was selected by the deadwood as an apprentice.

I just wanted to get a place in the Danding Sect, but I accidentally blackmailed all the alchemists, and I also got the identity of a pulse master in a daze.

I only wanted to learn the dot matrix technique when I went to the Array Sect, but I accidentally became the master of the Array Sect.

When he went to Qingshui City, he just wanted to kill the sky and not wait, but he was involved in a messy dispute to the south.

......

So this time when he came to the demon clan, Mu Yu promised that he would only be an easy-going guest.

But Mu Yu knew that things were not so simple, last time he beat Jiao Xinghua all over the ground looking for teeth, and he didn't see the other party come over to disturb him, obviously he couldn't say it, if he swallowed his anger, it would be strange if he was an arrogant and domineering dragon clan!

"Qiao Xue, the status of the four major dragon clans is so transcendent in the Blue Dragon Dynasty, why haven't they come to trouble me until now?" Mu Yu asked.

"They're not going to do anything here. Qiao Xue said.

"Why? I thought that the demon people with the true dragon blood looked down on the demon people without the true dragon blood, isn't it normal to come here to make trouble?"

"It used to be like this, but now this is Aunt Luanfeng's territory, she protects these demon clansmen, and will mercilessly throw out those dragon clans who dare to find fault. Qiao Xue said with a smile.

"Who is Luan Feng?"

"Luan Feng Demon King!"

"Wait, you still have a demon king in the demon clan?" Mu Yu was stunned.

Ten years ago, Aunt Luan Feng broke free from the seal, that is, from that time on, the demon clan without the true dragon blood really had their own status, and under the protection of Aunt Luan Feng, they could be on an equal footing with the dragon clan. Qiao Xue mentioned that the Luan Feng Demon King was still very respectful.

"Why didn't you tell me something so important?"

Mu Yu never knew that they had found a demon king ten years ago, he always thought that the demon clan now only had the Green Dragon Demon King and the White Ape Demon King and the Siren King who had just been rescued, and the sudden appearance of the Luan Feng Demon King really surprised Mu Yu.

"Is this matter important?Does Aunt Luan Feng have anything to do with breaking free of the seal?" Qiao Xue asked strangely.

Mu Yu touched his nose, as if it really didn't matter.

So far, Mu Yu has met several demon kings, and he also has a strange relationship with them, first released the white ape demon king, and then came into contact with the sand eagle demon king, and then saved the sea demon king, I feel that he and the demon king are quite fateful.

The birth of the demon king is a top priority for the demon people, they keep all the news very secret, although the human race still noticed some clues, but the matter of the Luanfeng Demon King breaking free from the seal was hidden from all the cultivators, it is really amazing!

"You didn't tell me earlier that I had such a close relationship with you, and I suddenly felt a little sad. Mu Yu sighed.

"I don't think there's any need to say this kind of thing, and you didn't ask me!" Qiao Xue said indifferently.

"Then there are no other demon kings in the demon clan now, right?" Mu Yu asked helplessly.

"No, we're still looking for other demon kings' sealing places. The reason why I brought you to Dawn Valley is because this is equivalent to Aunt Luanfeng's territory, oh yes, there is still Uncle White Ape, and Lord Siren King should also live here. Qiao Xue said.

"The three demon kings all live here, isn't it too crowded?"

"There are only a few areas where our demon people live, and other places are mixed, and dragons and demon people live together. Aunt Luan Feng was very dissatisfied with Grandpa Qinglong's approach, she felt that Grandpa Qinglong let the demon clan respect his descendants, which was unfair to other demon people, so Aunt Luan Feng built Dawn Valley ten years ago, and only demon people who did not have the blood of the true dragon were allowed to stay, and Grandpa Qinglong had no choice, after all, the top priority of the demon clan now was unity, so Aunt Luan Feng was left to do so. ”

"That Luanfeng Demon King is really a blessing for other demon people. Mu Yu couldn't help but admire the Luan Feng Demon King, who dared to do this in the Qinglong Dynasty, and was also a decisive person.

"Sister Qiao Xue, why do all the demon people take so good care of you? Xiao Shuai asked with a pouting mouth.

A clear spring bubbled up from Qiao Xue's fingertips: "Because of my ability to control water! In this barren area, water cannot be drunk indiscriminately, and the big river we passed through when we first came was flowing out of the ruins." It's very toxic, and if you drink too much, you will get poisoned, but fortunately, I can filter the poison, so I can provide them with pure water, and I can also use water to help them grow crops, so they take good care of me. ”

Qiao Xue's ability was hated when she was in the human race, but here the demon people regarded her as a treasure, which made Qiao Xue find the value of her existence, so she liked the demon clan very much.

"Little Brother Mu Yu, the old doctor asked you to go to him. Mei Hu twisted her thin waist and came to Qiao Xue's house again, her face was full of delicateness, and she threw a wink at Mu Yu.

Mu Yu is really helpless to this woman who is born with charm, every time she meets her, she has to send some autumn waves or something to herself, and she is unscrupulous in front of Qiao Xue, and sometimes she makes Mu Yu feel uneasy.

"I see, you guys talk slowly. Mu Yu got up and left the room and flew towards the old doctor's medical hall.

Since Mu Yu configured the prescription to help the two brothers of the nine-tailed cat solve the poison of the ruins, and told the old doctor the prescription for free, the old doctor was already impressed by Mu Yu, and from time to time he came to ask Mu Yu about some treatment questions, and Mu Yu also knew everything.

Living in this barren land, the demon people get sick from time to time. Maybe it has something to do with the ruins.,Many diseases are very difficult.,Sometimes you can't be cured by relying on your own cultivation alone.,Even the demon people in the merger period will even be tormented by some kind of disease.。

Everyone will come to the old doctor when they have diseases, and the old doctor has rich experience in treating diseases, but there are also many diseases that he can't help, such as even his own stubborn disease that cannot be cured.

"Mu Yu Xiaoyou, I'm not afraid of your jokes, I came to you today just to help me see, what's going on on my arm, often every once in a while, it will be like a fire, this pain hurts into the bone marrow, and even the spiritual power can't stop it, even if I use painkillers, it's useless. The old doctor rolled up his sleeves, exposed his upper arms, and said earnestly.

"Pain in your arm?"

Mu Yu felt very strange, he carefully examined the old doctor's arm, but did not find anything abnormal, no poisoning, no external injuries, nothing.

"What are the specific symptoms, such as what the attack is like, the interval between the attacks, etc., and when it hurts. Mu Yu asked.

"Not necessarily, but when I had a seizure, it felt like my whole arm was burning, and there were some strange patterns on my arms, and I still can't explain the situation," said the old doctor. ”

"Well, it's just a pattern, not only me, but many demon people have this situation, but everyone's attack is different, some people are hands, some people are legs, and the patterns are not the same, we have not been able to understand this matter, even the Qinglong Ancestor is not clear, so I thought about seeing if you can help us solve this problem. ”

The old doctor took out a book from the table and handed it to Mu Yu: "This is the pattern I recorded, the patterns that appear when everyone has a seizure are not the same, these patterns are irregular, we just wonder if we are poisoned by the ruins, but if we are poisoned by the ruins, people will die quickly, and we are still alive, so it may not be the poison of the ruins." ”

Mu Yu looked at the patterns recorded by the old doctor, these patterns were indeed very strange, like graffiti, some were composed of several lines, and some were gray markings. Mu Yu had never heard of this kind of thing when he was in pain.

"When did this disease begin?" Mu Yu asked, Mu Yu was also familiar with this kind of disease, and in the past, Father Deadwood used to take him to treat mortals who were sick with the plague or something.

"About a year ago! It's been almost two years, and suddenly many people have started to have this kind of situation, and the time of the attack is not fixed, some people have a seizure once a month, some have a seizure once every seven days, some people have a seizure once a day, and each time it doesn't last long, just a little while, and then it returns to normal, so many people don't pay attention to it, but I found a strange pattern. ”

"What pattern?"
