When the two came to the dissection room, Zhou Lao grabbed the Earth Flame Soul Destroying Stone with one hand and said, "This thing can evolve!" ”

"Evolution!?"

Xu Yang looked at Zhou Lao playing with the Earth Flame Soul Destroying Stone and wondered, "How did the stone evolve?" A monkey jumping out of a rock? Or do you turn into a stone man? ”

"It's neither, it's evolved into a Heart Flame Soul Destroying Stone."

Zhou Lao touched his beard and said with a smile: "I'm afraid that few people in the entire imperial city know this mystery, that is, only people as knowledgeable as me can know a thing or two." ”

"It's earthy black now, and it will turn into pure white when it continues to be burned with soul fire, which is evolution."

"This is what I told me when I was talking to a servant in the Imperial City."

"The last time he dissected a spirit beast, and then found the Earth Flame Soul Destroying Stone in the body of the spirit beast, but the Earth Flame Soul Destroying Stone was different, after the affirmation of the real person of Jiedan, it was the Earth Flame Soul Killing Stone, and the stone evolved in his body, but this spirit beast died, and the evolution failed."

"In the same way, the Earth Flame Soul Exterminator Stone that has not completed its evolution is useless, and it was a pity for everyone at that time!"

What a spirit animal, how to swallow it.

Is it possible to swallow such a stone bigger than your head? I'm not a spirit animal, and I don't have such a big mouth.

Xu Yang also didn't know what the difference was between evolution and non-evolution, how should stones evolve?

"Old Zhou, how should this thing evolve, and how much difference is there between the two after evolution!?"

Zhou Lao said very simply: "I don't know what the difference is between the two, evolution is simple, use your soul fire to nourish it." ”

Zhou Lao said this proudly, but in Xu Yang's opinion, he didn't say it.

"Old Zhou, I'll just forget your method."

"I don't have the ability to do what you said, thank you for telling me this useless trivia."

Xu Yang retrieved the Soul Destroying Stone from Old Zhou's hand and said, "You might as well tell me which materials it should be fused with to play a greater role!" ”

"That little old man doesn't know, and I don't practice swords."

"But you can ask Mei Fang about the soul fire, she has lived for hundreds of years, and she can't know a thing or two by nature."

"I'm telling you these things just to hope that you don't waste this hard-won material, if you can let her play to the extreme, then you have to find a way to make it to the extreme."

"It's also very beneficial for you in the future."

Xu Yang grabbed the stone and came out of Zhou Lao's dissection room, Zhou Lao was right, if he could play to the extreme, it would be the best.

After all, this Soul Destroying Stone was not easy to come by.

"Sister Mei Fang."

"Sister Mei Fang."

Xu Yang looked for Mei Fang everywhere, she often appeared when she didn't want to see her, and couldn't find anyone when she wanted to see her.

"Imp." Mei Fang suddenly appeared, startling Xu Yang.

Xu Yang turned around and said, "Sister Mei Fang, next time, can you not be like a ghost, you will be scared to death like this." ”

"Looks like you chose to stay." Mei Fang looked at the stone in Xu Yang's hand thoughtfully.

Xu Yang nodded: "I have something I want to ask you, you see, this is the Earth Flame Soul Extinguishing Stone, do you know what the soul fire means?" I've heard that you can nourish this stone with soul fire to further develop its value. ”

Mei Fang chuckled: "I know, but ordinary humans can't use soul fire, and if you want to use soul fire, you must at least have the level of a real person." ”

"But if it's a big demon and a spirit beast, then you only need to reach the innate before you can use soul fire."

"You kid want to nurture this stone, don't you?"

Mei Fang blinked at Xu Yang.

Xu Yang nodded, he didn't expect that the conditions for humans to use soul fire would be so harsh, he still has a long way to go before he wants to raise this stone, and he doesn't know that he has to wait until the Year of the Monkey and the Moon of the Monkey if he wants to cultivate this stone.

"So be it." Mei Fang picked up the Earth Flame Soul Destroying Stone and said, "I can help you cultivate it, but I have one condition." ”

"Really!?"

Xu Yang looked at Mei Fang in surprise, and now it seems that she doesn't seem to be so annoying.

"You'd better listen to my conditions first." Mei Fang said indifferently: "I want you to reach the realm of four steps and one yuan within a hundred years, do you think you can do it?" ”

"Yes!"

Xu Yang didn't even think about answering Mei Fang categorically, and the speed made Mei Fang startled.

"Are you so confident?" Mei Fang smiled: "Then I look forward to your success, and I will return this stone to you when I succeed in cultivation, but you have to help me do one thing after becoming a four-step yuanyi." ”

"Whether you succeed in this matter or not, you have to do it within a hundred years."

"It turns out that Sister Mei Fang, you are waiting for me here." Xu Yang smiled.

Although Mei Fang has achieved the strength of three steps and one yuan, she wants to break through four steps, but she is afraid that it will be impossible without a hundred years, so she hopes that she can break through within a hundred years.

As for this matter, Xu Yang guessed that it had something to do with her character, but she was afraid that Mei Fang would also cause a lot of trouble outside, so she hid in Shifang City and didn't go out.

"I see, I'll just promise you."

Mei Fang cut through her fingertips, a drop of blood floated in the air, Xu Yang did the same, and the blood of the two fused and then dissipated into the air.

This is a special kind of oath contract, once it is formed, both parties must complete the contract, and if the contract is broken, the other party will be attacked because of the oath contract.

A hundred years into the four steps of one? That's too simple, I'm already a three-step Yuanyi, even if the amount of experience required in the next step is large, I can reach the realm of four-step Yuanyi in three or five years at most.

Even in 10 years, it is not impossible.

I promised Mei Fang that I could take some time to help her do it at any time.

Xu Yang sensed the oath contract slightly, and then frowned, this Mei Fang really let herself do a very dangerous thing, and it happened to involve Linghai Temple.

"You just know it yourself, don't make a noise about it, otherwise you won't have a good life." Mei Fang reminded Xu Yang.

Xu Yang smiled helplessly: "Sister Mei Fang, you really let me get on the thief ship, you actually have something to do with that side, do you know that it is the top force in the East Pole." ”

Mei Fang snorted: "What, scared?" ”

Xu Yang waved his hand and said, "There's nothing to be afraid of, when I succeed in cultivation, I'll help you do this." ”

"During this time, I will help you cultivate this broken stone, you want to practice a sword embryo to come out, right, I will also help you figure out the material matter, and you don't have to worry about this sword."

"So much the best!"

Xu Yang gave up his hand slightly, and the matter of weapons was solved, so he could concentrate on fighting wits and courage with the big demon heads.

Break through into the four-step one? Isn't that hand-to-hand?

After Mei Fang finished speaking, she swallowed the soul destroying stone and disappeared in front of Xu Yang's eyes, Xu Yang who saw this scene was secretly speechless, and this mouth and human head could swallow it in one gulp.
