After figuring out the root cause, Xu Yi turned his words around and said, "Is the green color in these two demon cores related to the green goblin?" ”

He could already see that the cyan demon core from Langdu was also impregnated with green, but it was not as deep as the white demon core from Hu Jinghui.

And cyan and green are quite similar, and before he knew about the green goblin, Xu Yi couldn't infer the cause from the effect, and he couldn't see the clues, but it was normal.

At this moment, he carefully looked at Langdu's green demon core, and naturally could see the greenery impregnated in it.

Little Red Carp said, "Ah Carp doesn't know clearly, I only heard that the demon clan has become a green demon, and the demon core can be dyed green, and so far, the demon clan has obtained very few green demon cores, and everyone in the clan is researching, but because there are too few research objects, the East China Sea Demon Clan has fried the value of this green demon core to a very high level, if Engong has a favorite treasure, he can exchange it for this green demon core, and he will definitely be able to get his wish." ”

Xu Yi smiled, "You took these things back, how can I use them to exchange them." ”

said so, but in his heart, he had the idea that the black-green demon core was indispensable.

It's just that the little red carp is Chichen, he always has to be polite, so as not to take it too seriously.

What's more, he is familiar with the heart of this little red carp.

Sure enough, the little red carp immediately became excited, "Where does Engong speak, without Engong, I am just a chaotic little fish in the river, no different from a beast, maybe one day it will become someone's meal, where there will be today's opportunity." ”

"What's more, I strayed into the Demon Palace, if it weren't for Engong to save me, where would I still be alive. I went to the ruins of the Demon Palace to find these, just for the sake of Engong, if Engong didn't accept it, Ah Li's heart would be uncomfortable. ”

Xu Yi said, "Okay, don't be a benefactor, we will be brothers in the future." ”

The little red carp kept swinging its little head, "Don't dare, Ah Carp is not worthy, it's better to call Ah Carp Engong 'Gongzi' in the future, anyway, many customs of the human race, in the demon masses, are extremely common." ”

With a "childe", Xu Yi remembered Yan Zi, he had been out for a long time, and he really missed Yan Zi a little.

At the invitation of the little red carp, Xu Yi threw Langdu's mustard seed to the little red carp, and the little red carp had to resign.

Xu Yi said, "Even if you think I am a gift from your son, you can't shirk it." ”

The little red carp took the mustard seed and put it on its chest, and the mustard seed disappeared.

Xu Yi also learned to stick mustard seeds to his chest, and soon disappeared, as if they existed under the flesh and skin, between the blood and bones, but where they were, Xu Yi couldn't say.

And he has tried, the idea can be sent, but the mind can't be opened, I think it was specially created for the demon clan.

And in this mustard seed, it is not a vacuum like the Sumeru ring, but a world full of spiritual energy, which is somewhat similar to the scene in the spirit beast bag.

Without waiting for him to ask, he listened to the little red carp say, "The biggest difference between this mustard seed and the Sumeru ring is the inner world, the world in the mustard seed is extremely vivid, it can store monsters, open up the source of spiritual plants, and most importantly, there is a specific location where fresh ingredients can be stored, and the son should be able to see it." ”

Xu Yi sent his thoughts into the mustard seeds, and sure enough, he saw that there was a place that was separated into a small square by a shallow red line.

The thought reached out, and it seemed to be an enclosed space, very similar to the feeling in the Sumeru ring.

Mustard seeds are so wonderful, Xu Yi naturally has to use them.

At that moment, he contained all the items in the mustard seeds, including the sleeping Ice and Fire Rabbit, leaving only the Soul Flag, the demon corpse of the Saber-toothed Tiger of the Flood Desolation and other heavy treasures, in the Blood Hidden Ring.

Xu Yi said, "Since this mustard seed can hold living creatures, it seems that something is wrong, I don't know who among the demon clan can talk about it." ”

Mustard seeds, in his eyes, are the Sumeru ring, Xu Yi felt a little strange that the Sumeru ring could hold living things, but for a while, he couldn't say what the weird was.

Little Red Carp said, "I've heard this one said, and the most talked about is the disadvantages of mustard seeds for living creatures." Because once a living creature is installed, especially a living creature with thoughts, this Sumeru vow is very easy for that living creature to control. ”

"In this way, the gains outweigh the losses. Even if you only use mustard seeds as a treasure to carry, there is a great risk, because once the living creature in the mustard seeds has a bad heart towards you, it is impossible to have a chance to dodge such a close attack. ”

"Therefore, no one carries or stores living creatures with mustard seeds, unless they are loved ones. ”

"One more thing, the living thing is in the mustard seed, and it is completely in the hands of the person who holds the mustard seed, and the mustard seed is like a small world, and the person outside the mustard seed is like the master of this world, and can use his thoughts to obliterate the living thing in the mustard seed at any time. In general, no one takes such a big risk. ”

“............”

The little red carp said a lot, all of which he heard, although it was not messy.

Xu Yi also understood, and thought it was true, in a word, mustard seeds can survive, but few people do it, and the risk is too great.

After solving the mustard seed matter, Xu Yi began to think about the road ahead again.

Originally, he planned to leave the Demon Domain immediately.

Even if there is a star pattern on his chest, Xu Yi does not plan to stay here for a long time, in the final analysis, he is not a demon clan, and if he doesn't get it right, he will be exposed by someone.

When the time comes, huge risks arise out of thin air.

However, the appearance of these two green demon cores made him quite entangled in his heart.

According to the information he has received so far, there are only two ways to dissolve the petrification of meridians, that is, the means of transforming demons into demons.

One is to take the demon stone, and the other is to take the demon core of the demon above the second turn of the demon yuan.

The power of the latter is more pure, and Xu Yi's first goal was originally aimed at the latter.

But after seeing Hu Jinghui's methods, he basically lost hope.

Hu Jinghui is just a fourth-order demon, and he is at the bottom of the demon yuan second-turn demon, but his terrifying strength.

makes Xu Yi think about it so far, and he can't help but feel numb on his scalp.

Of course, he has Hu Jinghui's demon core in his palm, which is enough.

However, Hu Jinghui's demon core was dyed green, where did Xu Yi dare to use it rashly.

Now, the little red carp said that this green demon core is also extremely precious among the demon clan, and it can be exchanged for precious treasures, so Xu Yi will naturally inevitably think about it.

He decided to stay in the Demon Domain for the time being, and exchanged the green demon core.

Of course, the city government of the old demon will not send the green demon core out on the basis of finding out the situation, and it seems that he really has to stay here for a little longer.

At this point, he listened to Xu Yidao, "Ah Li, go out with me and see this demon domain." ”

Little Red Carp said, "The demon cave under the command of our Pingding Demon King is not vast, so we can only take Gongzi to walk around in a small area, besides, the Pingding Demon King knows that Gongzi has turned into a demon, and he seems to have the intention to recruit him, and he will hold a reception banquet for Gongzi in the evening, so we can't go for long." ”
