Zhang Yan looked at the Stone to Suppress Souls with a smile. Now it could not influence his soul energy anymore and he was able to carefully inspect it without the protection of the Purifying Lotus. This time, he walked around the stone to inspect it and found it was exactly a black stone, not special.
"Now the stone belonged to you and you can order it. But remember that it can only suppress souls and do not use it as a weapon to fight against people, otherwise it may be damaged." The lotus warned him.
He responded with a nod, "Got it."
He closed his eyes and began to mediate. Suddenly the stone started shaking, then shank into a sand and flew into the center of his eyebrows, floating on his Knowledge Ocean in still beside the lotus.
A happy smile climbed on his face and from then on, he completely owned the stone. With the protection of both the stone and the lotus, his soul would be so safe that nobody could attack him though his soul.
All of a sudden, the thick black fog covering the North Mountain began to dismiss, revealing the its original apperance.
He neglected the abrupt change of the mountain, and quickly leave its top for the Fengdu City. On the way, he used his soul energy to enter the stone once again, this time, facing no trace of resistance, reached its core and found the lingering soul sealed.
The black soul was still struggling to break the seal, but an invisible energy made all his efforts in vain. He could feel the fog's alarm.
He communicated with the soul depending on his own soul energy, "I guess you are the soul of the Anti-Soul Beast, right?"
"Boy, how can you have the ability to safely enter the stone?" Its voice was full of shock and incredible.
It added, "How did you enter? Are you suppressed too? But I didn't feel your soul. How did you do it?"
"How? The stone belongs to me now!" He replied with a cold smile.
"What?"
It screamed incredulously, then perceived the outside world with its soul energy and found it had completely lost the contact, which truly meant that Zhang Yan indeed owned the stone.
It tempted mildly, "Since the stone has been subdued by you, then let me go out and I will give you a lot of benefits."
"Benefits? What kind can exchange your freedom?" He asked with a smile.
It mused for a while and answered, "I can teach you the martial arts to cultivate your spiritual root. Although not immortal skill, it is of emperor-level, do you want to learn? As long as you let me go, I will give it to you."
He snorted and did not responded. His spiritual root had been growing all the time, so it was unnecessary for him to cultivate it. In addition, the Asura Change couldn't cooperate with any other body skills.
Tired of implicit, he came up with his thoughts directly, "Sorry, to be frank, I don't want any benefit from you. I can let you out, but you need to sign a soul-blood agreement with me and become my servant."
His words outraged the Anti-Soul Beast. But he did not care about it. He would rather let it die in the stone, if such a fierce ancient monster was not a servant of him.
The soul-blood agreement was an infrangible rule in the world. If the Anti-Soul Beast singed the agreement, its soul would be subject to Zhang Yan forever, which meant Zhang Yan could take its life easily as he wanted. There was only one way for it to remove Zhang Yan's control, that is, to get rid of the seal of the agreement. However, no one could do that in the world except for those immortal emperors.
