The old doctor was still flipping through a thick pharmacopoeia by candlelight, he was holding a pen in his hand, and he was recording several prescriptions for treating diseases that Mu Yu had explained to him in the past few days, and then bound them into a book.

This is his habit, every time he encounters any incurable disease, he will record and analyze in detail, and behind him is a tall bookshelf, which is full of all kinds of thick books, all of which are his medical experience recorded over the years.

"To treat the disease of the snail parasite, we need to use the crescent willow vine, this crescent willow vine cannot grow in this wild land, and the fierce sweat meat mushroom, these two herbs are difficult to find, it seems that when will I have to leave the demon clan again." ”

The old doctor shook his head, closed the pharmacopoeia, put down the pen in his hand, and sighed slightly.

In this barren land, the survival of the demon people has been severely challenged, and many parasites are very terrifying, even the rough skin and thick flesh of the demon people can't resist.

This is the top of the West, at the end of the Triple Continent, close to the mysterious ruins, and the harsh conditions mean that many of the healing herbs cannot be grown, and need to be picked on the territory of the human race.

The old physician often left the demon clan and secretly came to the territory of the human race to pick some herbs. Because he is a cultivator in the merger period, and he is completely transformed, he does not have the characteristics of a demon clan, so his own safety is not a big problem.

The old physician put the pharmacopoeia back on the shelf, blew out the candles, and went to the backyard to rest.

Not long after he left, Jiao Dahu and Jiao Da Wolf crept out of the shadows, the two of them came specifically for the old doctor's prescription, or more precisely for Mu Yu's prescription.

Dragons are not welcome in Dawn Valley, but it is not forbidden for dragons to step in. After all, they are all demon people, as long as the dragon people don't do too much, everyone is fine.

Because Dawn Valley is a pure land among the demon clans, there is usually a Xuanfeng Demon King in charge, so there is no need to worry about the dragon clan coming here to make trouble, so there is no one to guard or anything at night, which is also the reason why Jiao Dahu and Jiao Da Wolf can easily mix in.

Last time, they had already sneaked into the old man's house and stole three small silkworms, this time they infiltrated the old doctor's medical hall, ready to steal the old doctor's prescription and take it back to treat the jade dragon.

"Be careful, don't make any noise, if you alarm the others in Dawn Valley, neither of us will be able to eat and walk around!"

There are still a few demon clansmen in the Dawn Valley who are in the merger period, among which the respected old doctor is one of them, Jiao Dahu and Jiao Da Wolf dare not underestimate them, once they are discovered, maybe they can subdue the old doctor together, but they will definitely provoke other demon clansmen in the merger period, which is not good.

"It's okay, the residents here in Dawn Valley are not very vigilant, they don't close their doors at night, and they don't have any protective measures, haven't we all already succeeded once?"

"It's because I did it once, so I'm worried about whether they'll be more vigilant. ”

Jiao Dahu took down the pharmacopoeia from the bookshelf, and at the same time took out a night sacrifice spirit candle in his hand and lit it.

The candles are made from the fat of a monster called the Night Rite, which has a very special ability to illuminate the night with light, but this light can only be seen by themselves.

Candles made from the fat of the Night Ritual Spirit can only see the light of the person holding the candle, not others.

This candle is a thief's best companion, stealing at night without the need to be blind in the dark and without worrying about being spotted by the light.

The night sacrifice spirit shone in the hands of Jiao Dahu and Jiao Da Wolf, and the two of them quickly flipped through the pharmacopoeia recorded by the old doctor, and kept searching for the words "Desolate Poison".

The pharmacopoeia records many of the old doctors' experiences in treating diseases, and there are also records of curing the "poison of the ruins". But these are all figured out by the old doctor himself, and they are not what Jiao Dahu is looking for on this trip.

Jiao Dahu flipped the pharmacopoeia from beginning to end, but he didn't see the prescription about Mu Yu that the old doctor recorded at the end!

"What's the matter? Didn't the old guy write down the prescription?"

Jiao Da Wolf frowned, he continued to take down several other pharmacopoeias from the shelf, each one was carefully examined, it took nearly an hour, but there was still no trace of the prescription!

Jiao Dahu's face sank: "This old guy kept a hand, he didn't even write down the prescription!"

"Big brother, what should we do now? Do you want to take down that old guy while he is defenseless?"

"Can you use your brains, how can the two of us take him down quietly?" Jiao Dahu snorted coldly and continued: "Let's go, get out of here, this old guy often leaves the demon clan alone to go out to find herbs, as long as we wait for the rabbit, there will always be a chance!"

Jiao Dahu and Jiao Da Wolf extinguished the candles, submerged into the darkness again, and left the Valley of Dawn.

——

The next day, the old physician woke up early, and he was ready to leave the demon clan and go to the territory of the human race to pick some herbs. Many herbs are very scarce, not in the demon clan, and most of the living environments of herbs have their own habits, which need to be explored by the old doctor himself.

Early in the morning, he left the Dawn Valley alone, and there was a medicine boy in the old doctor's medical hall, but he usually went to the Terran territory to pick herbs, and he didn't like to take the medicine boy there, because the Terran territory must be very cautious, and the medicine boy also had the characteristics of the demon people, so it was not easy to hide his identity.

The old doctor's figure swept by in the morning light, and he flew towards the Heavenly Demon River with a familiar car. Flying over the Heavenly Demon River is the abyss, and after passing through the vast swamp, it is the realm of the human race. However, at this time, there was still some distance from the Heavenly Demon River, and he entered a forest.

But the old doctor frowned slightly, and his figure stopped on the trunk of the tree.

"Come out!" the old doctor looked at a large tree in front of him, sensing something.

"The old doctor is really so keenly aware, I really admire him!" Jiao Dahu clapped his hands and walked out from behind a big tree, looking at the old doctor with a smile, and at the same time, Jiao Da Wolf also appeared from behind the old doctor.

"What are you two doing here!" asked the old doctor in a deep voice.

Jiao Dahu smiled: "Old doctor, I heard that you already know how to cure the poison of the ruins, Lord Jade Jiaolong specially asked our brothers to invite the old doctor to come over." ”

The old doctor snorted coldly: "You don't know the principles of my medical practice, do you? I don't heal any dragon people in the North Shore Abyss!"

After the old doctor finished speaking, he wanted to leave here, but Jiao Dahu stepped out and stopped in front of the old doctor again.

"Old doctor, we are both demon clansmen, why do we have to see the outside world like that? Lord Jade Jiaolong is not an ordinary person, if you remove the poison of the ruins on his body, Lord Jade Jiaolong will definitely reward you heavily, and it is also your honor to be able to have a relationship with Lord Jade Jiaolong. Jiao Dahu still had a smirk on his face.

"I'm not unfamiliar with anyone's reward, and don't forget who drove me out of the royal city in the first place!" said the old doctor, a little angry.

More than ten years ago, the old doctor was practicing medicine in Wangcheng, and after Jade Jiaolong was framed by the black tiger in the hidden forest and poisoned in the ruins, Jade Jiaolong asked the old doctor to help him treat, but the old doctor's plan was to force the poison to amputate his left hand, where was Jade Jiaolong willing to agree?

Jade Jiaolong angrily denounced the old doctor as a quack, and smashed the old doctor's medical hall, driving him out of the royal city, so that he was not allowed to set foot in the royal city again for the rest of his life.

But who would have thought that now the old doctor has obtained Mu Yu's prescription and has become the only demon clan who can cure the poison of the ruins. At this time, Jade Jiaolong shamelessly wanted to ask the old doctor to help detoxify, how could the old doctor agree?

Jiao Dahu said: "Old doctor, what do you still mention about him in the past, the desolate poison plagues all the demon people, and from time to time there are demon people who die, you now have a prescription for treating the desolate poison, you should take it out to benefit all the demon clans together, not deliberately hiding your secrets, what do you say?"

"If any demon clan person comes to me, I will help him detoxify, but I will not help him except the Jade Jiaolong! You better go back!" said the old doctor categorically.

Jiao Dahu put away the smirk on his face and showed a fierce look: "So you are toasting and not eating and drinking?"

Step by step, the two slowly approached the old doctor, and the old doctor angrily rebuked, "What do you two want to do!"

"Old doctor, if you don't come with us obediently, then we will have to come hard. Jiao Dahu said and suddenly stomped on the ground, and a huge white net had appeared around him, trapping the old doctor firmly. They had come prepared for a long time, and set a trap here, waiting for the old doctor to enter the net.

The old doctor's face changed slightly: "You two are too bold, dare to do it here!"

"Old doctor, our brothers are just routine, please come to us as a guest!" Jiao Dahu stretched out his hand, and the big white net was violently retracted, firmly restraining the old doctor. This big white net is a magic weapon that the jade dragon has personally refined, and it is not something that the old doctor can break free from at all.

"You two let me go!" said the old doctor angrily.

But Jiao Dahu ignored him completely, and the white net emitted a spiritual power, blocking the old doctor's voice, and then the two people quickly disappeared into the woods with the old doctor.

But not long after Jiao Dahu and Jiao Da Wolf left, Mu Yu had already appeared in their original place.

"Sure enough, the matter has nothing to do with these two miscellaneous dragons. Long Teng snorted.

"Mu Yu, aren't we going to save the old doctor?" asked Mu Yu curiously.

Mu Yu looked at the disappearing back of Jiao Dahu and said: "Our purpose is to find the two little silkworms, Jiao Dahu and Jiao Da Wolf kidnapped the old doctor, but did not kidnap the silkworm uncle, which shows a problem, the two little silkworms must be in their hands." We need little silkworms to prove their innocence. ”

Although the little silkworm has not yet opened the spiritual intelligence, but the silkworm uncle can communicate with the little silkworm, if the little silkworm is still alive, they will tell the silkworm uncle what happened, and then who manipulated all this behind the scenes will be revealed.

"We need to follow these two guys to the North Shore Abyss to make sure that nothing has happened to the two little silkworms! But before we go to the North Shore Abyss, I need to go to the ruins!" Mu Yu said.

"What are you doing in the ruins?" asked Tatsuto, puzzled.

Mu Yu smiled slightly: "I don't think the Jade Jiaolong is poisoned deep enough, what do you say?"

The old doctor once told Mu Yu Jade Jiaolong about driving him out of the royal city, and also knew that the four major dragon clans framed each other and caused Jade Jiaolong to be poisoned by the ruins, so it seems that the Jade Jiaolong must be very jealous of the poison of the ruins, and Mu Yu must first figure out what the ruins are if he wants to deal with the Jade Jiaolong.

"You're going to—" Ryuto suddenly realized.

Mu Yu nodded, and then his figure disappeared into the woods.
