As Elder Guo paid the price and left with Lin Lang, the brothers and sisters of the He family and Gu Suchen were also quickly taken away by their respective elders. As for Ye Feng, he also returned to his residence with Xuanwu.

Back in front of the door of his residence, Xuanwu suddenly took out the mustard seed bag obtained from Elder Guo, erased the prohibition and threw it to Ye Feng.

"Fourth brother, go on. If you like something at this treasure conference, you can buy it directly, don't feel distressed. Anyway, it's not the spirit stones of our Nine Shadows Palace. Xuanwu said with a smile, without giving Ye Feng time to refuse, and with a shake of his body, he directly entered his own cave mansion in the residence.

Looking at the mustard seed bag in his hand, a trace of emotion flashed in Ye Feng's eyes. Then he also went directly into the residence, found his own cave and walked in.

The space in the cave is huge, and it is easy to accommodate 1,000 people. The surrounding layout is also extremely proper, no matter who can find any flaws, it is enough to see that this time the treasure pavilion of the treasure conference is also put into thought.

Walking over to the nearest futon and sitting cross-legged, Nightfeng had time to check the mustard seed bag in his hand.

The divine sense probed into it, and in an instant, Ye Feng's eyes widened, and a shocked look appeared on his face.

In this mustard seed bag, there are tens of millions of high-grade spirit stones scattered around!

Although Yefeng has a sword mound and can obtain some spirit stones from it, due to his limited cultivation, he can't get too many spirit stones from it at one time. Rao is like this, Ye Feng also feels that he is quite rich, and he is a small rich man. However, looking at the tens of millions of top-grade spirit stones placed in this mustard seed bag, Ye Feng couldn't help but gasp, and after a long time, he muttered to himself, and subconsciously said a word.

"Damn, these sects are really rich. ”

It took a lot of effort before Night Feng took his eyes off the mustard seed bag and solemnly put it into the storage ring.

It's not that Ye Feng's performance is unbearable, but that there are so many spirit stones in front of him, even some Mahayana monks may not be able to perform better than Ye Feng.

Closing his eyes, it took some effort to suppress the excitement of suddenly obtaining so many spirit stones, Ye Feng opened his eyes and transmitted the sound to his heart.

"Immortal Monarch, now you can tell me the mystery of Naling Chengmu Dan. ”

"This Immortal Jun thought that he had obtained so many spirit stones, and your kid had forgotten about Na Ling Cheng Mu Dan outside the Nine Clouds, but I didn't expect you to still remember it. Soon, the voice of the Heavenly Tribulation Immortal Monarch rang out.

"Well, this Immortal Monarch will tell you the mystery of this Na Ling Cheng Mu Dan. The Heaven Tribulation Immortal Monarch pondered for a moment, and then spoke again: "Although your second brother has temporarily suppressed the Na Ling Cheng Mu Dan, you should still be able to feel the rich wood attribute spiritual power that continues to appear in your body." ”

"Yes, although I am not in danger of turning into dead wood now, that spiritual power is still emerging. Nightfront nodded and replied.

"Hehe, that Ling Chengmu Pill is different from ordinary pills, it is not for taking. Instead, it is regarded as a mother pill, and a large number of sub-pills that can assist in cultivation and healing are born. Although the effect of the Heavenly Frost Continent's Naling Chengmu Pill was not as good as that had ever appeared in the Immortal Domain, it was more than enough to produce hundreds of Zidan. If you take it, how can the spiritual power it produce be consumed by a small out-of-body pre-monk of yours. If it weren't for Ben Xianjun, the night boy, you would have waited obediently to become dead wood. ”

"What is the effect of this pill?" Ye Feng thought for a while, and did not immediately ask how to break the spirit into a wooden pill in his body, but suddenly asked such a sentence.

"Below the merger period, all injuries can be recovered!" replied lightly, revealing a sense of confidence in his tone.

"Yes, then it seems that this Naling Chengmu Dan is another big help for me to participate in the Treasure Gathering Conference. Nightblade spoke.

"Kid, haven't you already swallowed the Naling Chengmu Pill, and how can it be another big help for you, you kid won't have been injured by the impact when he fought against that Lin Lang, right?"

"Immortal Monarch, what do you think this is?" Ye Feng said with a smug smile. Then he opened his mouth. Then, a ball of spiritual power flew out of his mouth and landed in the palm of his hand. It can be seen that what is wrapped in that mass of spiritual power is an elixir that has been digested and shrunk.

It is Na Ling Cheng Mu Dan!

"Night boy, you ......" Heaven Destroying Immortal Jun coughed, a little unsure of what to say.

"Hehe, although I swallowed the Naling Chengmu Pill at that time, I wrapped it with some spiritual power, and let it go little by little, so that the effect of the pill could be brought into play. Later, although I accidentally let go of the spiritual power for a while, I fell into danger. But after the second brother helped me suppress the Naling Chengmu Pill, I successfully wrapped it with my spiritual power, making it impossible to exert its efficacy. The spiritual power that emanated along the way before was just the residual medicinal power in my body. Ye Feng explained as he looked at the Naling Chengmu Pill in his hand.

"Night boy really has you, this Immortal Jun said that the effectiveness of this Naling Chengmu Dan suddenly weakened so much, at first I thought it was because of the level of the Heavenly Frost Continent, but I didn't want it to be your kid who did something in advance. The Heavenly Immortal Monarch let out a long sigh and said, "Night boy, I know what you want to ask next. I can tell you that this Immortal Monarch does know how to use this Mother Pill to produce a Child Pill. But the method that this Immortal Jun knows is also incomplete. This mother pill can produce up to half a hundred child pills, and then it will disappear. Whether you want to leave this Mother Pill in the Immortal Realm and then find a complete way to maximize the effectiveness of the Mother Pill or use the method of this Immortal Monarch now, Night Boy, you decide. ”

Hearing the words of the Heavenly Tribulation Immortal Monarch, Ye Feng didn't think about it, and said without hesitation: "I don't know when I will reach the time when I cultivate to the Tribulation Period and pass the Heavenly Tribulation Flying Immortal Realm. At that time, I still couldn't remember that this Naling Chengmu Pill was not certain, let alone had a complete method. Therefore, I chose to use the method of Xianjun. ”

"Okay, since you said so, then this Immortal Monarch won't say much. Listen, the way to catalyze the mother pill to produce the child pill is to ......" The Heavenly Immortal Jun laughed, and did not hesitate, and directly informed Ye Feng of the method he knew.

After learning the method of catalyzing Na Ling into Mu Dan, in the next few days, Ye Feng locked himself in the cave mansion and catalyzed Na Ling into Mu Dan without leaving home.

Finally, the night before the Treasure Gathering Conference, with a roar, Ye Feng finally succeeded. At this moment, in his storage ring, the Naling Chengmu Pill had disappeared, and in its place, there were thirty Zi Dan neatly put together!
