As soon as Luo Lin said this, the donkey Xiaohei understood the master's intentions, and he couldn't help but be extremely happy, if his master could get the weird attack method of the human-faced white fox, then their strength would be greatly improved.

Next, Rollin sent the donkey Xiao Hei and the little skeleton Brian and a few wind wolves to find the wind whistle for himself, while Rollin sat cross-legged next to the corpse of the human-faced white fox.

The reason why he didn't even have time to treat the injuries on his body for the time being was because after the death of this human-faced white fox, if it took a long time, then its soul would dissipate, and at that time, Luo Lin would have no hope of subduing it.

Although the human-faced white fox was cut off by himself with a golden trident, this did not prevent Luo Lin from performing the 'Undead Sacrifice' on it, because the soul of the demonic beast existed in the skull just like humans.

"Whew...... This is the first time to refine this sixth-level demonic beast, and I don't know if it can be done!" Luo Lin couldn't help but beat a little drum in his heart, because the more advanced the soul, the difficulty of its sacrifice will also increase dramatically, and when he subdued the third-level or even fourth-level undead before, the success rate was 100%, but when he subdued the fifth-level demonic beast Mighty Bear, there were two cases of failure.

Luo Lin attached great importance to this human-faced white fox, because he really wanted to get that kind of weird attack ability, so Luo Lin sat here cross-legged and adjusted for a while, and when his mental state reached its peak, he began to perform undead sacrifice on the human-faced white fox.

For the soul that has just died, the undead sacrifice is divided into two parts, the first part is to transform the soul of the other party into the 'undead', after the transformation, its soul will not dissipate between heaven and earth.

The second part of the undead sacrifice is the process of subduing, after transforming the soul of the other party into an undead, the undead spirit does not belong to you, and you must continue to refine it and 'subdue' it, so that the undead will become your subordinate completely.

At this moment, Rollin is carrying out the first part of the undead sacrifice, the transformation of the undead!

As an ancient and obscure magic spell was pronounced, an extremely strange wave swept towards the head of the human-faced white fox.

However, when this strange fluctuation had just come into contact with the soul in the white fox's skull, Luo Lin felt an extremely strong resistance!

The human-faced white fox soul resisted so strongly that it bounced away from that wonderful fluctuation for a while!

"Even if it's a sixth-level demonic beast, the resistance shouldn't be so fierce!" The white fox soul reacted so much, which made Luo Lin startled, even though he had made sufficient mental preparations before, but he was still suppressed by the other party's 'dismount'.

"Isn't the white fox very resentful of me? It's not right, it almost killed me before, and I reported it back, I was stronger than you, and I killed you, it shouldn't have any grudges!" Luo Lin muttered, but he didn't stop transforming the soul of the human-faced white fox.

Under Rollin's control, the wonderful fluctuation came into contact with the other party's soul again, and what was obtained was another strong resistance from the other party.

In this way, Luo Lin tested the soul of the white fox again and again, and as the number of temptations increased, the strange fluctuations were also consumed little by little, and the fluctuations on it gradually weakened.

"Hey, it's still a failure!" After testing the white fox's soul dozens of times, the strange fluctuations finally dissipated completely, and Luo Lin could feel it, the soul of the human-faced white fox was also lost, if the time dragged on a little longer, then the other party's soul would soon all dissipate, and at that time, there would be no hope of controlling the other party.

Therefore, Luo Lin did not dare to be the slightest slack, and after the failure of the first undead transformation, he immediately recited the magic spell and began the second undead transformation.

However, after a period of attempts, Luo Lin's second undead transformation also ended in failure, and at this moment, the soul of the human-faced white fox dissipated a lot.

According to Luo Lin's estimate, if he still can't complete the undead transformation in the third time, then the other party's soul is estimated to have all dissipated!

"It's strange, why is this human-faced white fox so repulsive to my undead transformation!" Luo Lin couldn't help but ponder.

"This human-faced white fox doesn't know when it followed us, and then, after I summoned a seventh-level demonic beast purple-veined wolf king with 'undead enslavement', when the seventh-level magic crystal nucleus was about to be devoured by Xiao Hei, it suddenly came out and wanted to snatch this seventh-level magic crystal nucleus, and after I put the magic crystal nucleus away, it fought with me, and then was killed by me......"

"In this process, this human-faced white fox should have no grudges against me......"

Luo Lin's mind couldn't help but quickly flash the scenes after the appearance of the human-faced white fox before, because he knew that if this demonic beast had a great grudge against him before his death, then it would be much more difficult than usual to perform undead soul refining on it, but after thinking about it, what he did seemed to have no place that could cause the other party's resentment.

If you want to kill me, you can't do it, but you will be killed by me, your skills are not as good as people, and you will die in the hands of the other party, this should be the most resentful way to die, but how can the soul of this human-faced white fox feel so abnormal......

"Hey, could it be ......" Luo Lin suddenly thought of something, that is, the seventh-level magic crystal nucleus that the human-faced white fox did with himself!

"Could it be that his soul is obsessed with this seventh-level magic crystal nucleus that he has never obtained in his lifetime, which is why he has such an abnormal behavior?"

Thinking of this, Luo Lin couldn't help but take out the seventh-level magic crystal core from the undead space.

However, as soon as the seventh-level Demon Crystal Nucleus fell into his hand, his 'Dark Perception' that had been surrounding the soul of the human-faced white fox was keenly sensed, and the white fox's soul suddenly emitted a violent fluctuation!

"It really has something to do with this magic crystal nucleus!" Luo Lin couldn't help but be overjoyed, and immediately, he gradually approached this seventh-level magic crystal nucleus to the head of the human-faced white fox.

As the distance between the two gradually got closer, Luo Lin could clearly feel that the fluctuations transmitted by the soul of the human-faced white fox were becoming more and more intense.

When Luo Lin placed the seventh-level magic crystal nucleus directly in front of the human-faced white fox's head, the fluctuations of the soul in his skull gradually calmed down, and Luo Lin could feel that the slightest fluctuation from his soul was much softer than before!
