"Ahem...... That's all there is to it. Cheng Xuan said to himself in a deep voice in the cave.

Then Cheng Xuan dragged his sick body into a shocking flight out of the cave and flew to the depths of the Demon Spirit Island, where the purple mist filled the sky above the demonic canyon and stopped.

A flash of fire sank into the purple mist, and the tanuki in the canyon was startled, took the transmission note, and flew out of the cave after a while.

Above the fog, Cheng Xuan and the tanuki stood opposite each other. "Heh, is this fellow Daoist here to talk to me about a deal?" the tanuki smiled and spoke first.

"Well, yes, I don't have a long time to die, and I want to make this deal, and my son will be entrusted to you in your care on this island in the future. Cheng Xuan said calmly.

"Okay, my son is also very optimistic about him, and the spiritual pressure may have been released by your son last time. Tanuki nodded.

"Okay, haven't you asked for the name of Daoist Friend Zun?" Cheng Xuan said respectfully.

"My name is Mo Li, Daoist friends are so polite, the transaction is like this, I need you to help me refine the Alien Yuan Pill, as long as I agree to this, the many demon beasts on Demon Spirit Island are all your friends, and your son can come to us if he encounters any trouble in the immortal cultivation world in the future." How?" said Mo Li the terms of the deal.

"It's feasible, but the alien pill is a rare pill in the world, Cheng may not be able to refine it for you in this life, but my son can refine it for you in the future, as long as I can reach your protection in the human world, I will agree to this condition." Cheng Xuan said with a look of surprise on his face.

The Alien Pill is a rare pill in the world, and since the Great War of Immortals and Demons, the Alien Pill has rarely appeared in the world. Occasionally, a Alien Pill will appear in the Secret Market, but it is rare. The alien pill is to improve the level of the demon beast after the transformation period, there are very few pills in the world that can make the demon beast advanced, the cultivation of the demon beast is extremely difficult, and the promotion to the transformation period is also very long, and it is even more difficult to advance when it reaches the transformation period, although the life span of the demon beast is very long, but if the advancement fails, it means that it will never be able to advance, so the birth of the alien pill brings hope to many demon beasts.

It is also very difficult to find the materials for refining the Alien Yuan Pill, there are a total of thirteen flavor elixirs to refine, and the main materials are only available in that kind of dangerous place. The refining steps are also very complicated, and it is not so easy to refine.

"That's very good, in this case, I'll take care of your son a little now, and when your son can refine the pill for me in the future, let's refine it, and the transaction will be like this, you go back and tell your son, if you have any difficulties in the future, come to me directly, this is my token." After Mo Li finished speaking, a folding fan appeared in his hand and threw it towards Cheng Xuan.

Cheng Xuan took the folding fan, hugged his fists and saluted, and flew back to the cave.

Mo Li looked at Cheng Xuan's back and smiled silently, and nodded silently: "For the sake of his son, he did not hesitate to make such a deal with our demon beast, but he also met me." Hey!" and then Mo Li returned to the purple mist.

Cheng Qian was practicing exercises in the cave, and a flash of fire flew in, Cheng Qian opened his eyes and took the transmission note, and then collected his efforts and walked towards the alchemy room.

As soon as I entered the alchemy room, I saw my father, who was meditating, pushing two pills in front of him.

"Well, Qian'er handed over to you today for his father to refine the Bigu Dan, and there is one more thing to be handed over to you to complete. When Cheng Xuan saw his son come in, he opened his mouth sternly.

"Yes, Daddy. ”

"Okay, you come here, Daddy now tells you, the names of these two herbs, this one is Xinchen Grass, and the other is Cabbage Grass. These two elixirs are the main medicinal materials for refining Bigu Dan, and they can be refined by adding a little ginseng essence. Cheng Xuan pointed to the two piles of spirit grass in front of him and said.

"Okay, you first calm and contemplate it, and try it for the sake of the father and the refining in the future. Bigu Dan, although it is easy to refine, but it also needs to be familiar with it, and it only takes three days to complete the refining of Bigu Dan. Cheng Xuan began to use the spiritual power of his whole body to urge the alchemy furnace in front of him and said.

As soon as Cheng Xuan's spiritual power urged, the earth fire swooped up, quickly wrapping the Dan furnace, and he saw that the earth fire around the Dan furnace was rotating around the Dan furnace in a spiral shape.

Cheng Qian was surprised when he saw this father's method of controlling the fire, but he didn't say it, he just quietly admired his father's alchemy, and thought, "I must become like my father in the future." The fire control of the real alchemy is really beautiful. "Indeed, those who have cultivated to a high level can do it handy, and those who control the fire of alchemy can do it handy.

The Dan furnace was already burned red, Cheng Xuan's right hand pointed to the elixir in front of him, and the new dust grass entered the Dan furnace first, and after refining for five hours, he controlled the cabbage grass to be put into the Dan furnace, and then controlled the fire on the ground to speed up the rotation.

Cheng Xuan was sweating profusely, as if his body was weak, the spiritual power in his body was tumbling, and the toxins in his body began to run wildly. On the morning of the second day of refining, due to the long-term consumption of spiritual power, the toxins in the body were not well suppressed, and a mouthful of black blood spurted out of Cheng Xuan's mouth.

Cheng Qian's heart was beating when he watched from the sidelines, and he wanted to go over to comfort his father, but Cheng Xuan stopped him, and then insisted on continuing refining.

The function of the Bigu Pill is to save the low-level monks who have not yet built the foundation from the spiritual elixir of hunger, as long as they eat one pill of Bigu Pill, they can be exempted from eating anything for ten days. It can make the low-level monks better retreat and practice.

Cheng Xuan slapped his waist with one hand, and a jade bottle appeared in his hand, and then a white liquid was poured out of the jade bottle, and the essence of the human body was slowly injected into the Dan furnace.

Then I heard the crackling sound in the Dan furnace, and the elixir inside began to melt and fuse, and after a few hours, there was no sound in the Dan furnace, and the earth fire was still rotating around the Dan furnace at high speed.

On the third day, bursts of medicinal incense began to emerge from the Dan furnace, and Cheng Qian, who smelled it, also knew that it was about to condense the pill, so he watched his father refining the pill more carefully.

After about half a day, the Dan furnace began to squeak, and the aroma became stronger and stronger, and finally a muffled sound was heard, and Ning Dan succeeded.

Cheng Xuan's spiritual power urged, and the earth fire was quickly put away, lifting the lid of the furnace, and hundreds of glittering pills flew out, one by one into the jade bottle beside him.

"Okay, Qian'er refining the pill for your father, you can be regarded as a serious observer, rest for a while, and then you will try to refine the Bigu Pill.

After Cheng Qian rested for a while, he also began to learn from his father to refine the Bigu Dan in a decent way. But the fire is still the same, wrapped in the Dan furnace for a while, and I shook my head vigorously when I saw it,

......................................................

In the end, Cheng Qian only refined a few dozen pills in total.

In the evening, Cheng Xuan called his son to the cave: "Qian'er, time is running out for my father, I went to find the tanuki a few days ago, and made a deal with him, my father can't complete it, you will complete it in the future, there is a jade Jian and Danfang here." In the future, if there is any difficulty for the father, he will go to the tanuki, and his name is Mo Li. ”

"If the child obeys his father's teachings, he will definitely cultivate well and complete the things entrusted to me by his father in the future. I'll find my brother. Cheng Qian said with a little whimper.

"Okay, what's it for. There's a token here, it's from Namori. Cheng Xuan said with an extra folding fan in his hand.

Cheng Qian carefully put it into the storage bag: "I know." ”

Cheng Xuan took out another letter: "In the future, when you arrive in Yuanguo, please give this letter to Elder Wang of Cloud Sword Sect and ask him to introduce you to Cloud Sword Sect." ”

"There are some low-level spells here, such as the Spirit Eye Technique, the Great Strength Technique, the Light Body Technique, and a high-level spell, the Ice Needle Technique. In the future, I will slowly cultivate, and there will be the flight of the imperial weapon, Daddy doesn't have many materials here to refine the flying magic weapon, and I will learn it myself when I go to the Yuan Kingdom in the future. Okay, you go down!" Cheng Xuan took out another jade slip and said

"Father, sit down on your own in a few days, and you will be taught what you should teach. Okay, let's go out and practice. ”

Cheng Qian put the things given by his father into the storage bag one by one, whimpered and walked out of the cave. ..................
