Gul'dan's skull was already in front of him, scorched by the flames of the altar, radiating darkness in all directions, causing the entire Forest of Felwood to fall into corruption.

Su Chen stretched out his hand, but there seemed to be a low whisper in his ear, like a whisper of a soul.

"It's the language of the orcs, is that Guldan's soul talking......" Su Chen's heart trembled slightly.

Gul'dan was also a man of mad power pursuits, even more so mad than Illidan, who risked the future of the entire orc clan for the sake of power, and even went so mad that he went deep into the tomb of Sargeras, which led to his own death.

The Dreaded Demon Kings around the altar seemed to be saying something, but Su Chen couldn't understand the language of these demons at all, and Zhi Brain could only analyze the general meaning.

The two stronger Dreaddemon Kings stood up in front of the altar, trying to stop Su Chen from continuing to approach Guldan's skull.

However, as Su Chen's changing abyss demons let out a roar full of anger, those demons beside him actually retreated one after another, and some of the weaker demons even knelt down on the spot.

"This roar is a perfect replica of Manolos's voice, both in terms of audio and timbre, and even every fluctuation of power." Zhi Brain was showing off in his mind with some pride.

If it weren't for the limitations of its appearance, perhaps it would have been perfectly disguised as Manolos.

Of course, in Su Chen's opinion, the reason why it could be simulated so realistically should be related to the fact that the demon blood he drank originally came from Manolos.

He took the opportunity to snatch the little head off the altar.

"What a strong force!" When the small skull was held in his hand, Su Chen immediately felt a strange power coming from the skull.

The head had been at the hands of the Blood Fiend, Naozu, and Deathwing, and now it had finally fallen into his own hands.

"You're not really a demon? That's it...... I can feel your true soul, you are human! The whispers in my ears were replaced by human language this time, and it seemed to contain great shock.

"Oh, you can sense my soul? But you'd better not play any tricks. Otherwise, I'll crush this bone right away! Su Chen was very surprised that Guldan had been dead for so long, and the power of his soul was still so strong, and he even immediately realized his true identity.

"I didn't expect that a human would dare to pretend to be a demon, and dare to snatch my head in a group of fear demon kings, human, I admire your courage. If you are willing to cooperate with me, I can give you infinite power, and endless knowledge and demonic mastery......"

"I do have a lot of things I want, but that's not what you can give." Su Chen whispered, he didn't dare to believe the words of this madman, Guldan, now he had to leave here as soon as possible, leaving these temporarily intimidated Dreaddemon Kings.

With the help of Zhi Brain, he was barely used to running on four legs, although the steps seemed a little funny. But with the hideous body of the Abyss Demon, knocking down a large number of trees along the way, it still looks like the momentum is still undiminished.

"Human, I am shocked by your greed, do you know where my power comes from? That's Kil'Gardan, one of the commanders of the Burning Legion, and if you're willing to work with me, I'll make you the leader of an army of demons that can conquer a kingdom! ”

"I'm sorry. I am now a king, and the greatest kingdom of mankind. ”

“……”

The whisper in my ear fell silent for a moment. After all, he was unwilling to be lonely and sounded again: "Human, your ambition needs to be a little more ambitious......"

"Don't tell me you can conquer the whole world, you must know that neither Kilgardan nor Akmund have been able to conquer this world as you said before."

"......" Gul'dan's voice finally fell silent again.

"How are we going to harness the power of this skull?" As soon as he was a little away from those demons, Su Chen asked Zhi Brain a little impatiently, he was unwilling to cooperate with Guldan, but it didn't mean that he didn't use his power.

"Of course, it's about acquiring as much knowledge and skills as possible. Although the knowledge and power I have mastered are powerful, many of them are not suitable for this world, and if you rely solely on analysis to obtain the skills of this world, it will take too long, and it is more efficient to obtain them directly. ”

"Oh. So do we really want to work with them? I can't trust this guy. "Su Chen really had a hard time believing that Guldan, this kind of guy who can even give up his own people, even his own life, must have done anything, and the ghost knows what conspiracy will be behind his back.

"Of course, you don't have to cooperate, just find a demon slave contract with soul restrictions to restrict him, and then I can obtain all the knowledge he has through the contract."

"It's that simple? But this guy is not afraid of death at all, and we may not be able to get him to sign the contract. Su Chen was a little worried in his heart, with Guldan's attainments in dark magic, even if he crushed this skull, he might not be able to annihilate his soul.

"No one is not afraid of death, he is not afraid of just thinking that his soul will be immortal and one day he will be reborn, you can let him see the sorrow of frost, I believe he will make a decision with interest."

Su Chen didn't expect that Zhi Brain would also be so black-bellied, but Frost Sorrow has the ability to devour souls, and may indeed be able to truly threaten Guldan.

Finally came to a secluded place, Su Chen immediately found out the Frost Sorrow that he had hidden under the demon's armor, this sword had become much larger with the change of his body size this time, and it looked even more hideous and terrifying.

The small skull of Gul'dan was not even as large as the small skeleton carved on the sword, but when it was brought close to the Frost Sorrow, Su Chen could feel the skull in his hand trembling violently.

Even if he had seen it scorched by the mysterious flames on the altar before, he didn't have such a big reaction.

"This sword...... This side of the sword...... What exactly do you want to do? Are you really willing to give up that infinite power, knowing that no one in this world knows those demons better than I do. Gul'dan's voice was no longer as calm as before, and he seemed to be extremely afraid of the sorrow of the frost, so he had to try to tell his usefulness and strength.

"I really don't want to give up, otherwise I wouldn't have risked robbing you, but I don't like to cooperate, you should know what I mean."

"So what do you want to do......"

"Slave, a demon slave soul contract, if you don't want to sign it, I will immediately use this sword to smash this skull, for a soul as powerful as yours, this sword must be very fond of it."

"Slave ...... Damn, don't let this sword come near me, I'm willing to sign anything, get this sword out of the way, take it as far away as possible. (To be continued.) )

PS: Happy New Year's Day, everyone! I've been so busy lately that I've almost forgotten the date......
