Together, Long Yu and Hong Ying walked into the central hall and came to the black sarcophagus.
Under the control of the residual soul of the girl Zhitao, the Thunder and Fire Yin Blade flew out from Hongying's small world and remained silent around the black sarcophagus.
"Alright, let's get started, otherwise we will have to shut down the lightning and fire traps around the hall one by one, which will waste at least two hours."
Long Yu waved his hand and said to the Thunder Fire Yin Blade: "Do you think there is any way to break open this sarcophagus made of the Black Domain Divine Stone?"
Only the girl Zhitao knew how to crack the sarcophagus.
"It is impossible to crack the Black Domain Divine Stone by brute force, so you must have skills. Basically, all high-level weapon refiners can smelt the Black Domain Divine Stone. However, due to the characteristics of the Black Domain Divine Stone, the cracking methods of the Black Domain Divine Stone tools refined by each weapon refiner are different, and you need to follow the methods and rules set by them."
The consciousness of the girl Zhitao's remaining soul came out: "I do know how to crack my grandfather's sarcophagus, but you must swear not to destroy my grandfather's body. Can you do it?"
"You can rest assured. We only want the colorful crystal powder, and... once the colorful crystal powder is taken away, no one else will come here to disturb your grandfather."
Hongying nodded and said.
Including Long Yu nodded. He had no interest in an old man's corpse, let alone destroying the remains of the Thunder and Fire Demon Saint. Why would he do something that would not benefit him at all?
Although the old man may have a lot of good things on him, for Long Yu, getting the colorful crystal powder is enough. One should not be too greedy. What's more, all this was obtained because of Zhi Tao. Long Yu still doesn't want to go against her request.
When the girl Zhitao saw the two of them nodded in agreement, she told them the method to crack the sarcophagus made of the Black Domain Divine Stone, letting Long Yu and Hong Ying know.
Of course, to crack the sarcophagus, the secret technique of thunder and fire is still needed, so Hongying can't help much, and only Long Yu is busy here.
Fortunately, the process of cracking the sarcophagus was not difficult. It only took Long Yu an incense stick of time to crack it open. Then he saw that the entire sarcophagus began to melt and a small hole appeared.
"Hey, there's only this small hole that can be opened. Quickly take out the colorful crystal powder inside."
The girl Zhitao urged.
Long Yu remained vigilant the entire time, and even now he still did not completely trust the remnant soul of the girl Zhi Tao. However, he soon realized that the girl really did not have any other thoughts and had not lied to him.
As Long Yu used the secret technique of thunder and fire to condense the divine text, he finally took out a pile of powdery substances from the small hole in the sarcophagus, showing different colors in them: red, orange, red, green, indigo, blue and purple, which happened to be the seven colors of the rainbow!
Seven colors of powder are mixed together, and it seems that it is impossible to separate them. No matter how finely they are divided, they definitely contain seven colors. These seven colors seem to be completely blended together, but it seems that they can be distinguished from each other. It is very magical.
The weight of this pile of colorful powder is exactly the seven taels that the girl Zhitao mentioned. According to the market price in the demon territory, it is enough to sell for 140 billion demon coins!
Even for the Blood Demon Clan, this was a rare and huge sum of money. Even Hong Ying had never held so much money before. For a moment, she couldn't help but be dazzled.
It’s not that Hongying hasn’t seen things of such high value before, but she has rarely owned them. To be honest, there are many good things in the Blood Demon Clan, but they are all the property of the Blood Demon Clan, and even Hongying is not qualified to touch them.
"Brother Long, we've made a fortune!"
Hongying's eyes lit up.
"Alright, alright, let's get out of here quickly. It would be bad if someone catches up and sees us."
Long Yu waved his hands, feeling quite happy in his heart. After collecting the colorful crystal powder, he turned around and left.
Hong Ying did not ask Long Yu for the colorful crystal powder, but quickly took the Thunder Fire Yin Blade and followed Long Yu out of the large hall in the center.
After they left, the pitch-black stone coffin in the center of the hall slowly healed, and the small hole on the Black Domain Divine Stone that was broken by Long Yu gradually recovered as if no one had ever been there...
…
There are seven taels of colorful crystal powder in total, but Long Yu doesn’t need so much.
"I have four rainbow stone eggs. I only need four ounces of seven-color crystal powder. The remaining three ounces can be given to Hongying."
Long Yu never forgot that he was cooperating with Hong Ying. Even though he taught Hong Ying the method of practicing balanced control, he still had to give Hong Ying what she deserved.
So after coming out of the hall, Long Yu took out three taels of seven-colored crystal powder and handed it to Hong Ying while preparing to leave.
"You really don't want it? Actually, if you want it, just take it all. It's useless to me. If you give it to me, I'll just sell it for money."
The red oriole smiled leisurely.
"Then I'll keep it for now and talk about it after we leave this tomb. By the way, what do you plan to do, Sister Zhitao? Will you leave with us?"
Long Yu thought of the remaining soul of the girl Zhitao who was still in the Leihuo Yin Dao.
"Let's go with you. Anyway, there's nothing to stay here. I want to go back to the Thunder and Fire Demon Clan first."
The girl Zhi Tao said cautiously. She was really afraid that Long Yu and Hong Ying would turn against her. If they shattered her soul on the spot, she would not be able to resist at all.
The only thing that made her confident was that she had only told the two of them how to practice the first three levels of the Thunder and Fire Secret Art. If Long Yu and Hong Ying completely defeated her, she would have no chance of knowing how to practice the rest of the levels.
However, Hong Ying really likes the girl Zhitao. As for Long Yu, he has no hobby of harming girls. Zhitao was already very pitiful, and the sudden galaxy explosion destroyed her. Long Yu doesn't want to bully such a poor girl's soul.
"Then let's go for a walk on Thunder Mars."
Hongying nodded and made the decision on behalf of Long Yu. It wouldn't take much time anyway.
"But we can't just leave like this, Brother Long. Let's change our appearance quickly, in case we meet someone who recognizes us when we go out."
Hongying said to Long Yu.
"I think so too."
Long Yu nodded, then used the power of the Book of Shadows to transform himself into a kitten!
This kitten, on the surface, looks like an ordinary kitten. It is not a demon cultivator and has no martial arts realm at all. It is just an ordinary pet.
Seeing this, Hongying smiled and nodded with satisfaction: "If we still leave as a man and a woman, even if we change our appearance, people will still get suspicious, but it's good enough that you become a kitten."
After saying that, Hong Ying transformed into a charming woman wearing pink gauze. She hugged Long Yu, who had transformed into a kitten, in her arms, and pressed her hand against his fair and flawless skin before flying directly toward the outskirts of the Demon Saint's Tomb.
Hongying's ability to transform illusions is absolutely first-rate, and her attainments in this area have definitely surpassed many ordinary Great Master realm practitioners.
With her transformation like this, even if her brother Hong Jun stood in front of her, he might not be able to recognize her identity, let alone other practitioners who were not familiar with her.
A charming woman, holding a kitten in her arms, was walking through the endless dark void, which seemed very suspicious. However, at this moment, Hongying actually exuded the aura of a great master. Even Long Yu admired her camouflage ability.
At most, Long Yu can rely on balanced control to hide his aura, but Hong Ying can transform and disguise herself as a strong man in the realm of the Great Overlord. Long Yu feels inferior to this level of means.
Soon, the two encountered the first person, a middle-aged woman who was also at the Great Overlord realm. When the two met, they didn't say anything and just passed each other.
The middle-aged woman seemed to have obtained a lot of good things in this demon saint's tomb. She ignored Hongying and went straight to the deeper part.
Hongying's route when going out is very particular. She does not go directly out, but goes out in circles. This way, if she meets people, the other party will not think that she came out from the center, thus saving a lot of trouble.
Long Yu turned into a kitten and was held in Hong Ying's arms. Feeling her soft and warm skin, he couldn't help but feel a little distracted, but he quickly suppressed it and began to think about the refining of the rainbow stone egg and the seven-color crystal powder.
Long Yu has four rainbow stone eggs, which are mainly red, black, blue and white, and can be used to refine four kinds of heaven-defying elixirs: the Magic Sky Pill, the Void Pill, the Eight Extremes Blood Pill and the Holy Soul Heaven Pill.
Among them, the Magic Sky Pill and the Void Pill can greatly enhance the degree of compatibility between the practitioner and the divine text. The Eight Extremes Blood Pill can allow the practitioner to give birth to the Eight Extremes bloodline, while the Holy Soul Heaven Pill is equivalent to an enhanced version of the Magic Dust Heart. After taking it, one can regenerate the body infinitely within one hour.
No matter which pill it is, its effect is absolutely incredible and can greatly enhance the practitioner's strength, so Long Yu is very concerned about it.
In addition to the rainbow stone eggs and colorful crystal powder, a lot of auxiliary materials are needed to refine these four kinds of pills. However, they are all relatively common materials. Although their value is not low, it should not be difficult to buy them with Long Yu's current assets. The key is that rare materials like colorful crystal powder that are priceless are no longer needed.
“As for the alchemist, Liao Lele, who owns the Bitter Sea Medicine Cauldron, is not sure if she is qualified to refine this heaven-defying elixir now. But after all the materials are collected, she can give it a try!”
Long Yu was thinking in his mind that the next step was to go to the trading house to buy all the remaining auxiliary alchemy materials needed, and then he could prepare to make the alchemy.
Of course, Liao Lele's martial arts realm is only at the peak of the emperor realm now, and he has not yet stepped into the one-star emperor realm. It is a bit difficult for him to refine this kind of heaven-defying elixir, but Long Yu can buy some creative objects and let Liao Lele's martial arts realm be raised to the one-star emperor realm. In that case, it is still possible to refine the heaven-defying elixir with the help of the bitter sea medicine cauldron.
