The spirit stone is a natural thing, and the color of the low-grade spirit stone is bluish, containing a small amount of spiritual energy, which is suitable for low-level monks to cultivate; The medium-grade spirit stone is blue, and the spiritual energy in the medium-grade spirit stone is enough to support the cultivation of the Yuan Infant stage cultivator, and it is the most common cultivation thing in the cultivation realm; The high-grade spirit stone is red, and the aura contained in it is enough to support the cultivation of monks in the Mahayana period and even the Dongzhen period; The best spirit stone is purple in color, and is generally used to restore the true element during the tribulation.

It is said that there are perfect grade spirit stones on top of the best spirit stones, but no one has ever seen them.

It is extremely extravagant to use high-grade spirit stones to cultivate in the cultivation realm, and the sect master of the Nine Star Sect is also reluctant to use high-grade spirit stones to cultivate, and when cultivating, they all absorb spiritual energy from heaven and earth, and slowly accumulate their own heritage.

There are not many top-grade spirit stones in the entire cultivation realm, and most of them will not be consumed, and they are generally used as reserve resources.

The best spirit stones are even rarer, and the best spirit stones can only be found in the secret realm of the ancient sects.

Ban Fu looked at Duan Wuxian with some red eyes, "Seeking Demons" is not only a complete top-grade spirit stone, but also a pass to the Demon Realm.

At the beginning, the "Forgetfulness Order" that Ban Fu got was the same as the effect of "Seeking Demons", both of which were passes to another realm.

"Ah, I'm scared to death!" Immortal Emperor Feng's voice sounded in Ban Fu's mind.

After Mo Yixi appeared just now, Immortal Emperor Feng became mute, and no matter how Ban Fu called Immortal Emperor Feng, he was silent.

Now that Mo Yixi has just left, Immortal Emperor Feng has come to life directly, how can Ban Fu not be angry.

"Old fellow, I just called you, why didn't you keep quiet?" Ban Fu was very angry, and his tone was no longer as respectful as before, in the past, Ban Fu called Immortal Emperor Feng "Immortal Emperor Master".

At the beginning, Ban Fu and Immortal Emperor Feng had made a Dao heart oath, but the situation was so critical just now, but Immortal Emperor Feng didn't say a word, this was the oath that Immortal Emperor Feng reneged on first, how could Ban Fu not be angry.

Immortal Emperor Feng smiled bitterly and said, "Do you think I don't want to respond to you?" I don't dare to speak out! ”

"You're a dignified Immortal Emperor-level figure, and there's something you're afraid of?" Ban Fu didn't believe in Immortal Emperor Feng's statement at all.

"Immortal Emperor? Now it's just a lost dog! Immortal Emperor Feng smiled bitterly and said, "Do you know who the person who appeared just now?" ”

"Do you say Mo Yixi, how could I not know that Duan Wuxian has already told me his origin. You're not afraid of him, are you? The dignified Immortal Emperor would be afraid of an immortal, wouldn't it be ashamed to spread it? ”

"Huh, immortals?" Immortal Emperor Feng sneered: "He is not an ordinary immortal, he is the only saint in the demon world. ”

"Demon Saint?" Immortal Emperor Feng's words set off a monstrous wave in Ban Fu's heart, "The Demon Realm Saint can come to this realm at will?" ”

"Why not? The Demon Realm, the Immortal Realm, and the Human Realm are just different planes in themselves. As long as you find the exact spatial node, it is not difficult to travel back and forth between the two realms. ”

"Since immortals can travel back and forth between the two realms, why aren't there any immortals in this realm?" Ban Fu asked the doubts in his heart: "Even if the node is difficult to find, in hundreds of thousands of years, there will always be monks who happen to find the space node." ”

"How do you know that there are no immortals in this realm?" Immortal Emperor Feng asked Ban Fu rhetorically: "You don't know it's just because your realm is not enough." ”

"Besides, the aura in this realm is already very scarce, after ordinary immortals come to this realm, not only will their cultivation not only not be enhanced, but will also regress, do you think there will be a monk who has crossed the tribulation to come back?"

"I see." Ban Fu suddenly realized.

The monk has gone through a lot of hard work to improve the realm, and after returning to this realm, he will even go backwards, and no one wants to come back.

"Mo Yixi should have felt my presence just now, otherwise he would definitely not come to you." Immortal Emperor Feng said guessingly: "In this case, how dare I respond to you." ”

Ban Fu touched his nose in embarrassment, and said apologetically: "It's me who blames you, I apologize to you, I'm sorry!" ”

Immortal Emperor Feng saw Ban Fu's apology, considering that the two would have to cooperate in the future, he smiled and said: "You are still a child, I don't care about you, but this is the only time to take the next example." ”

"You hurry up and find a place where no one is around, I want to see if the gourd is in what I want."

……

......A loud bang came from a distance, and I saw a ragged Taoist flying into the air quickly.

"Who sucked away the aura of heaven and earth and stood up for Lao Tzu!" The Taoist shouted angrily in the air.

The first thing that came to Ban Fu's mind was Mo Yixi's move just now.

"It's Elder Ji!" Duan Wuxian recognized that the Daoist in the air was Elder Ji who Duan Wuwu and Tian Min had rescued at the beginning.

Elder Ji vented his anger in the air, and Duan Wuxian didn't dare to step forward to explain the situation.

Fortunately, after a while, a high-ranking cultivator of the alliance came to dissuade Elder Ji, and Elder Ji fell from the sky.

Seeing that Elder Ji was not releasing coercion at will, Duan Wuxian took Ban Fu and his party towards the place where Elder Ji lived.

Everyone came to a small courtyard, and through the courtyard gate, Banfu saw that there were no extra items in the courtyard except for the bluestone pavement.

Duan Wuxian bowed outside the door and saluted: "Duan Wuxian brought his inner son to meet the elders." ”

"I'm in a bad mood today, don't bother me!" Elder Ji's tone was obviously not good, and he didn't know what was going on.

"This ......" Duan Wuxian hesitated for a moment, not knowing whether to say what happened just now, what if Elder Ji implicated him.

"I know a little bit about what just happened." After thinking about it, Duan Wuxian still said this sentence.

After all, there were many people who saw Mo Yixi's gathering of aura with one hand just now, as long as Elder Ji sent someone to investigate, he couldn't hide it at all.

"Bang", the courtyard door suddenly opened, and Duan Wuxian felt as if he was being held by an invisible big hand, and flew towards the courtyard quickly.

Ban Fu was worried that Duan Wuxian was in danger, so he hurriedly followed Duan Wuxian and ran towards the courtyard.

If Elder Ji was not a kind person, he would be killed on the spot by virtue of Ban Fu's act of trespassing on the courtyard gate.

"Say it! What the hell is going on? ”

As soon as Ban Fu arrived in front of a stone house, he heard an inquiry coming from inside the house.

Ban Fu took a long breath, and it seemed that Duan Wuxian had nothing to do for the time being.

"At this time, it has something to do with Mo Yixi's predecessors!" Duan Wuxian threw Mo Yixi out first, so that even if Elder Ji was angry, he didn't dare to vent it easily.

Duan Wuwu said the matter in a few words. , and then waited for Elder Ji's questioning.

Elder Ji pondered for a long time, he didn't expect that this matter turned out to be a ghost caused by Mo Yixi. It seems that this loss cannot be recovered from Mo Yixi.

The low-level monks didn't know Mo Yixi's character, but Elder Ji knew very well that the four described Mo Yixi's character - moody.

Mo Yixi will be angry because of a trivial matter, do something that destroys people, and will also give the other party a generous reward for a trivial matter.

It can be seen from Duan Wuwu's matter that two thousand years have not changed Mo Yixi in the slightest.

"Take out the token that Mo Yixi gave you and I'll take a look!"
