When Xue Yun was still talking about the blood of the wind spirit in the secret room, Lu Tong's figure disappeared in the secret room in an instant, and she didn't even see how Lu Tong pinched the seal method and disappeared, you must know that even the teleportation printing method could not disappear so quickly, and Lu Tong left even faster than the demon king Shi Xuan.

It's just that Xue Yun didn't know that Lu Tong was still in the secret room, but Lu Tong didn't have time to greet Xue Yun when he heard Ling Yun's surprise and entered his inner world.

In the inner world, Lu Tong looked at Ling Yun there and said in ecstasy: "Little boy, I have found an elixir that can quickly restore essence and blood, but this elixir is not so easy to refine!"

Lu Tong looked at Ling Yun with great joy and said, "If there is no difficulty, is it still called an elixir?" If not, isn't it that the bloodline of the demon clan can reproduce indefinitely!"

"I have taken a look at this elixir, and there are a lot of things that are needed, and it is not something you can refine now, you had better take a look at these herbs first!" said Ling Yun and handed the prescription for refining the elixir to Lu Tong.

Lu Tong looked at the medicinal materials on it and couldn't help frowning, the prescription was very simple, only five flavors of medicinal materials, Xuanling Fruit, Five-Clover Grass, Yin Lingzhi, Ruthless Flower, and Heavenly Spirit Water. Only the five-flavor medicinal herbs have only been heard of by the five-leaf clover Lu Tong, and the remaining Xuanling Fruit, Yin Lingzhi, Ruthless Flower, and Tianling Water are all names that have not been heard of, at least in the Cod Spirit Continent, no wonder Ling Yun is so weird, it seems that it is not easy but very difficult.

But in order to be able to practice the Twelve Heavens Book, Lu Tong has to find these medicinal materials in difficulty, and now that he has a prescription, he doesn't have to worry about not being able to find medicinal materials, even if there is no one in the demon world, can it be said that there is no one in the elf world?

Ling Yun looked at Lu Tong and smiled slightly and said, "Xiao Tong doesn't talk about other medicinal herbs, just the Heavenly Spirit Water is the treasure of the Upper Realm, do you know what the Heavenly Spirit Water represents?"

Lu Tong shook his head, Ling Yun looked at Lu Tong and said in detail: "Heavenly Spirit Water is the water flowing from the Stygian Spring in the Underworld, and the reason why this kind of water is rare is because the Stygian Spring will only flow out some water in ten thousand years, and most of those waters are the medicinal primes used by the Emperor of the Underworld Ring to refine the elixir, and there are very few Heavenly Spirit Water that can be left!"

That's why it's named Heavenly Spirit Water, and the other Heavenly Spirit Water is called the Spirit of the Stygian Spring! And the one used to refine the elixir that can replenish the essence and blood is the Heavenly Spirit Water of the Spirit of the Stygian Spring!"

Lu Tong frowned slightly and looked at Ling Yun for a long time before he spoke: "Does that mean that even if there is a prescription, you can't refine the pill?"

"Let's not talk about whether you can find all the medicinal materials, even if you find the medicinal materials with great difficulty, can you guarantee that you can refine them at one time? You must know that refining the pill requires a large number of medicinal materials as a foreshadowing, how many pills have you refined by yourself now? Can you guarantee that you can refine this pill?" Ling Yun's words made Lu Tong suddenly realize.

Lu Tong has been practicing magic, soul method, and formation since the beginning of his practice, although he has learned alchemy with the old man of Tianxin, but it is only limited to knowing the medicinal effect of medicinal materials and an ancient book of elixir, if he allows himself to refine, Lu Tong believes that he can definitely refine it, but it is unknown whether it can succeed at one time, but now the rarity of medicinal materials can only be tried by Lu Tong once.

Now Lu Tong is like a cat on the shore who sees the fish swimming around happily in the water, and the fish in the water also jumps out of the water from time to time to stimulate the cat on the shore.

Now Lu Tong can only see but can't use it, obviously it is close in front of him, but he can't use it, which makes Lu Tong have mixed feelings, looking at Ling Yun and not knowing what to do.

Ling Yun saw Lu Tong's doubts and said, "Just because you can't find it doesn't mean that the Demon King of the Demon Realm can't find it, I believe that the Demon King must have a way to find an alchemist who can successfully refine this pill in one go!"

Lu Tong didn't speak after hearing this, he knew that the demon world would definitely be able to find such an alchemist, but Lu Tong knew even more that the demon world would have to pay a lot of price in this way, because the rarity of these medicinal materials Lu Tong was clear, looking at Lu Tong frowning slightly, Ling Yun didn't speak again, she also knew that Lu Tong was choosing, the demon world could certainly refine such an elixir, but at the same time, he lost more, what Lu Tong would lose after choosing the demon world to refine this elixir.

Even if the demon world has the help of the elf world, all the medicinal materials can be found, but the heavenly spirit water is a thing of the underworld, and if you want to get the heavenly spirit water from the underworld, Lu Tong doesn't dare to think about what it will take.

Lu Tong looked at Ling Yun and said, "Let me think about it, this matter is not easy to decide!" After speaking, Lu Tong pinched out a seal and came out of the inner world, Xue Yun, who was still puzzled in the secret room, was even more puzzled when he saw Lu Tong appear out of thin air again, but when he saw Lu Tong, who was more confused than himself, he frowned slightly.

Lu Tong was still smiling before leaving, but now when he came back, how could he be so preoccupied, and he didn't even have any change in his expression when he stared at him.

Xue Yun looked at Lu Tong and said, "Is there anything that can't be solved?" It's just that Lu Tong still didn't react, Lu Tong was louder than the other three times in a row before Lu Tong looked at Xue Yun and said: "Let me be quiet first, I have something to decide, there is a secret to the use of wind spirit magic in this secret room, you might as well take a look!"

Xue Yun glanced at Lu Tong a few times and said, "You think about it slowly, since there are spells to cast the wind spirit qi here, I'll take a look at these spells first, and just say it when you think about it!"

Lu Tong nodded and walked towards the secret room, and when he walked to the door of the secret room, Lu Tong turned to look at Xue Yun and said, "I'll go out first, you can read the books here at will!"

After finishing speaking, he turned around and left under Xueyun's surprised gaze, Lu Tong walked aimlessly on the Demon Spirit Peak after leaving the secret room, not far away was the cliff, Yuluo and the Demon King went down to the bottom of the cliff there, Yuluo didn't know when he would come back, if Yuluo could still have someone to discuss, Lu Tong's mind was blank at this moment.

The temptation of the Twelve Heavenly Books is too great, and in addition to the fact that the Twelve Heavenly Books can be used with the Eight Gate Dunjia, Lu Tong is not only eager for the fusion of the Wind Spirit Qi, but now that Xueyun is in the secret room, he only needs to forcibly fuse the Wind Spirit bloodline of Xueyun to achieve fusion, but in that case, Xueyun will suffer inevitable damage, either falling or falling forever, which Lu Tong does not want to see.

The prescription is available, but the pill cannot be refined, and Lu Tong is wandering back and forth at the moment, and he can't pay attention to it......

In the secret room, Xue Yun frowned slightly when he looked at the books, there are not only the spells of the wind spirit qi here, but also the running route of the thunder spirit qi, and the fusion and rejection between the five elements of the spirit qi, every book here has never been seen directly before, just when Xue Yun saw how the wind spirit qi was cast quickly and faster, Xue Yun instantly got up and recalled Lu Tong's eyes.

That kind of look was helpless from the heart, could it be that Lu Tong was choosing something? And Lu Tong's figure who went out just now was clearly preoccupied, why didn't he say it, although this is the Demon Spirit Palace, it is still somewhat dangerous, and Xue Yun ran out of the secret room in an instant.

The moment he ran out of the secret room, he saw Lu Tong wandering back and forth there, Xue Yun had already determined what choice Lu Tong must have made, otherwise Lu Tong would definitely not be like this, and he would not have spent a good time not cultivating but walking around.

Xue Yun looked at Lu Tong who walked over and was slightly stunned, and it took a long time for Xue Yun to make up his mind to walk towards Lu Tong, because Xue Yun had already thought of why Lu Tong was like this all of a sudden, and the reason was very simple, it must be because of the fusion of blood.

Xue Yun already knew that he had multiple missions from the moment he saw the patriarch and the demon king find himself together, maybe he would never have the consciousness of autonomy in the future, after all, if the blood was fused, he would definitely lose a lot of essence and blood, and if he didn't pay attention to himself, he would never recover.

And Lu Tong looked like he was fighting against himself, Xue Yun looked at Lu Tong and said, "Are you struggling with the matter of blood fusion?"

Xueyun's words made Lu Tong raise his head and look at her, with a complicated mood in his eyes, Lu Tong didn't know how to answer, so he looked at Xueyun quietly for a while.

After a long time, Xueyun spoke: "I already knew my ending when I met you, since I chose it, I won't regret it, just like the demon king said, then I am nothing more than a regression in the cultivation realm and there is no danger to my life, so you don't need to dwell on it!"

After a long time, Lu Tong spoke: " You are ready to sacrifice, but I can't accept it, so even if I can fuse the bloodline of the wind spirit, but the demon will accompany me for a lifetime, making me feel guilty, I have found an elixir prescription that can quickly make up for your bloodline, but the medicinal materials are too precious, I am deciding whether to tell the demon king, or I am looking to see if there are other pills that can be replaced, the wind spirit star soul vein will not be weaker than the five elements in the wind attribute star spirit soul vein, so I will not agree, even if the Eagle Eye clan agrees, I will not agree.

You must know that the Hawkeye Clan must have paid a great price for cultivating you, because I lost the Hawkeye Clan on the surface, but there must be a knot in my heart, which is not conducive to the future development of the demon world!"

Xue Yun looked at Lu Tong and frowned slightly, Xue Yun had never thought about it so much, but Lu Tong thought about it, after all, the demon world is a place where he will always live in the future, Lu Tong looked at Xue Yun and said: "Although I now really want to fuse the wind spirit bloodline, and even desire, I can't deceive myself about this, but I have my principles and bottom line of being a man, I can't hurt others because of my selfishness, and I look down on myself like that."

So I have to make a decision like a complete solution, I must not do things that harm others and benefit myself, so that even if I can become the strongest, then I am lonely, I used to be lonely once, I will not go to the most important thing because of the supreme martial arts, that is, joy, a real strong person, should not be lonely!"

Xue Yun blinked at Lu Tong suspiciously, she didn't seem to understand Lu Tong's words at all, but as if she understood something, Lu Tong smiled slightly at this moment: "In the demon world, I want to be a happy powerhouse!" So I must get along in the most appropriate way, so that the Hawkeye clan will at least be friends after I become a strong man instead of someone who has been very good to me!"
