Taking out the Demon Spirit Stone from the storage space, Sun Yu looked at these black Demon Spirit Stones and felt a little pain in his head.

He had studied this magic spirit stone before, but unlike the spirit stone, no matter how he absorbed the things in this spirit stone, this spirit stone was still unmoved, and after Sun Yu studied it, he found that he couldn't use these, so he threw these spirit stones aside.

"I'm afraid this Demon Spirit Stone is somewhat useful, do you remember the Demon Venerable Throne? It is made of this stone, generally speaking, in addition to the symbol of power, the throne must still be able to assist its cultivation, and this Demon Spirit Stone must be the same, otherwise this system will not give you this Demon Spirit Stone as a system reward." ”

After thinking for a while, Du Jiu said.

Sun Yu nodded, but before he found the method of research, he was equivalent to having a treasure, but he didn't have the key to open the treasure chest.

"Don't worry, there must be some way, how did you urge this demon spirit stone before?" Dujiu Yu asked Sun Yu.

"Naturally, it is like using spirit stones to inject divine consciousness into it, and then urge the spiritual power in it to merge it into your body, is there anything wrong?"

Although he was very puzzled why Du Jiuyou asked this, Sun Yu still honestly told Du Jiuyou everything.

Dujiu You's brows tightened, he always felt that something was not quite right.

"Perhaps, this demon thing is not quite the same as ordinary things. "Dujiu You is also a little unsure.

Now Sun Yu regretted it a little, why didn't he ask He Xiao properly before he came? They must have known how to urge this damn demon spirit stone.

"I'll take a look!"

Ha Er grabbed the Demon Spirit Stone in his mouth, then put it under his own hand and began to study it slowly.

Sun Yu's already broken right hand is still dripping blood, but now Sun Yu has no magic power in his body, and the system has not judged him to complete the task, so he has no way to upgrade, so naturally there is no way to replenish the magic power in his body.

Sun Yu seemed to forget that his right hand was still injured, and he waved his right hand violently, and blood beads dripped down Sun Yu's arm.

"Master, be careful!"

Seeing that Sun Yu didn't cherish his hands so much, Ha Er was a little angry.

Although it is the Erha clan, as a healing holy beast, he can heal a lot of wounds, but for him now, if Sun Yu's hand is crippled, there is no way for Sun Yu to regrow his severed limbs.

After being scolded by Ha Er, Sun Yu was a little embarrassed, and quickly withdrew his hand, but after making such a fuss just now, Sun Yu's demon blood was sprinkled on the ground, and some of the demon spirit stones were stained.

In a place where Sun Yu Dujiu Youha'er couldn't see, the Demon Spirit Stone slowly absorbed Sun Yu's Heavenly Demon Snow, and then suddenly burst out with a burst of red light.

"What is this!"

Sun Yu saw a burst of red light explode under his feet, and Ha Er, who was on the side, was also startled and almost jumped up.

"This seems to be the Demon Spirit Stone just now. ”

As soon as Dujiuyou's words came out, this made one person and two ha calm down.

"Master, I find that you have changed. ”

After composing, Ha Er said this sentence quietly.

"Huh?"

Sun Yu was a little speechless, what was the dog thinking.

"You seem to be a lot less calm than you used to be. ”

As soon as Ha Er's words came out, Sun Yu wanted to hit it, and now he is enduring the pain of the continuous corrosion of the toxin, if he can still calm down and cool naturally, then he is not a heavenly demon, but a saint.

Just when Sun Yu wanted to refute, Du Jiuyou suddenly spoke again.

"Sun Yu, calm down, since you transformed into a demon, there are indeed some things that are not the same as before. ”

Ha Er nodded as he picked up the Demon Spirit Stone and handed it to Sun Yu.

Sun Yu frowned, and wanted to refute a little, but when the words came to his mouth, he swallowed them.

Has he really changed?

The demon blood has changed his bloodline, changed his race, will even his heart be changed?

"I originally thought that it was Evil Lan who planted the demon seed in your heart, which made you give birth to such a big change, but now it seems that things are not so simple. ”

Dujiuyou's voice was a little dignified, but now was not the time to discuss this.

The Demon Spirit Stone was already bright, and a large amount of magic power rushed to his face, and Sun Yu was like a thirsty traveler who had been in the desert for a long time, frantically absorbing the magic power in it.

The magic power is converted into spiritual power, and then passed on to Ha Er, who uses his racial talent to heal Sun Yu's right palm, which has been eaten by more than half of the toxins, and because Sun Yu is a heavenly demon, his own physical strength is extremely strong, and the regenerative ability of the body is also extremely strong.

"This spirit scorpion venom is really strong, obviously the system has made this spirit scorpion venom your toxin, but this toxin originally attached to the scorpion can still corrode your body, this ghost spirit scorpion is a bit interesting, and I don't know what the demon soul spirit scorpion will look like. ”

Du Jiuyou was a little emotional.

Sun Yu's palm was slowly recovering, although it seemed to be just a small injury, and it didn't seem to be much compared to those who had severed limbs at every turn, but only those who had experienced it could know how terrifying it was to feel like the toxin slowly corroding the flesh on his body.

If it weren't for Sun Yu's experience of blood exchange, I'm afraid he wouldn't have been able to persevere in this corrosive pain.

Although the body was regenerating, the cannibalizing pain was still surrounding Sun Yu, his lips were a little pale at this time, and after he heard Du Jiuyou's words, he said slowly: "Didn't you follow that old-timer, how could you not have seen this toxin?"

The red-tailed spirit scorpion venom, this poisonous Dujiuyou hasn't told him about it yet.

"This poison is indeed extracted by the old guy from thousands of poisonous insects in the Hongmeng Realm, but I don't know how to turn it into two kinds of spirit scorpions now. ”

Du Jiuyou shook his head, indicating that he was not very clear about this.

Sun Yu was silent, if it wasn't for the old-timer's tricks, then there would be only one explanation.

System...

This system has no name and no surname, and Sun Yu still doesn't know what kind of system it is, but the tasks it has assigned, as well as the mysterious rewards, have made Sun Yu a little overwhelmed.

I don't know when he will be able to completely solve the doubts in this system.

Time passed, and when there was still an hour before the end of the mission, Sun Yu's injuries were completely intact.

During this period, Sun Yu was not idle, he kept looking for the location of the formation in the array, but there was still no more discovery.

"It's getting too late. ”

Sun Yu stood up, now that his magic power had recovered, and all the injuries on his body had been healed, except for the occasional sour pain in his right hand, everything else could be ignored.

"Wang Pin's hidden formation, I really haven't seen it, old man, this time, it can be regarded as a long experience. ”

Du Jiuyou sneered, and began to dangle his purple mist body in the passage.

Now that they are free from the restraint of the spirit scorpion, their movement has become easier.

Sun Yu stood up and knocked on the wall beside him, but nothing changed.

Sun Yu began to look at these walls in a daze, and suddenly, he had a not-so-good guess.

"Hey, old fellow, do you remember when we came? Isn't it strange that this place has been made into a grave, but there is nothing in this passage?"

When Sun Yu came here, he felt that something was wrong, but he didn't think much about it at first, but now it seems that there are really some twists and turns in it that he didn't figure out before.

Dujiuyou's eyes lit up, and he drifted to Sun Yu's side and began to examine the walls carefully.

"At that time, there was no other entrance, so we could only choose this entrance, that is to say, at that time, we had no other way than to go here, Sun Yu, can you confirm with the system that the Venerable is being imprisoned here?"

Sun Yu nodded and passed Du Jiuyou's words to the system.

Today's system is extraordinarily cooperative, and even obediently said: "Yes." ”

But other than this yes, the system doesn't have too many words.

"Since it's here, there must be a passage. ”

Sun Yu settled his mind and had a guess in his heart.
