"The key to the Bone Tower?" Ishihara pondered for a moment, then said what he had just judged, and said: "The key to the Tower of Bone Bones should be the art of sacrifice, only it can catalyze the bone beast that takes a lot of time to conceive in a short period of time. ”

"Shi Daoyou is really good eyesight. The Black Soul Daoist raised his head and looked at Ishihara with some surprise, this junior really gave him a lot of surprises, although he said it a little vaguely, but he had already pointed out the key to it, and immediately let go of some contempt in his heart, and said with a bit of solemnity:

"The method of sacrifice and prohibition is indeed the key to the Bone Tower, among which the method of sacrifice used by the old man is the blood sacrifice of the dead soul, which can communicate the legendary world of the dead spirit, and transform the grievance and soul power into the qi of the dead body, thereby greatly accelerating the birth of the bone beast, and its blood sacrifice sacrifice requires the blood spirit forbidden to transform countless beast blood into a special spirit blood, both of which are the secret of my evil soul island, and Shi Daoyou can see at a glance how many of them are fundamental, which is really extraordinary. ”

No wonder he didn't recognize the law and prohibition of sacrifice. Ishihara's brows stretched, he couldn't think of what kind of prohibition this was after carefully identifying it for a long time just now, it turned out to be the inheritance of Evil Soul Island, and Qu Soul was also an unlearned and unskilled person, except for some evil law refining tools and alchemy, he didn't learn much about other things on Evil Soul Island, so he didn't know that there was such an evil law prohibition inheritance on Evil Soul Island.

That's right, the ban does not distinguish between good and evil, many evil cultivators have studied the strange forbidden inheritance, he is also less involved, only the top forces of evil cultivators such as Evil Soul Island have inheritance, and since then, the role of the Bone Tower is very clear, after the Bone Tower absorbs the sea beast into the tower, the blood spirit ban extracts the flesh and blood into sacrifices, and the soul of the sacrificial beast is transformed into the qi of the dead world, and then it can quickly transform the remaining skeleton into the bone beast, forming a large number of cannon fodder, and it is really a good arsenal that is not wasted.

For the level of the Black Soul Daoist, Ishihara is extremely admired, even if it is the body, except for the prohibition and refining weapons, which may be on par with him, the rest of the aspects are much worse, and he is worthy of being a member of the Shengong Group that can represent the top level of Tiangong Island.

However, correspondingly, the sacrificial techniques and prohibitions he performed were not something that ordinary people could master, if he wanted to refine the Bone Tower, there were not many monks in the entire Hall of Sin who could help share these two steps, so even if he had the White Bone Tower as a pedestal, it would take a lot of time for him to transform it into the Bone Tower, and he urgently needed a helper to help him.

There is no doubt that Ishihara is a helper chosen by the Sin Temple, and sure enough, after briefly introducing the key to the cultivation of the Bone Tower, the Black Soul Daoist said:

"Although the battle situation on the front line has temporarily stabilized, at most, the sea beasts can accumulate enough beast tide power for ten years, so the Sin Hall does not have much time to waste, at least a batch of resentful bone towers must be delivered within ten years in exchange for front-line support, I am afraid it will be difficult to complete this with the strength of this seat alone, so I need your help, this seat will directly teach you the blood spirit forbidden, you and I work together, we should be able to sacrifice and practice a hundred resentful bone towers within ten years"

"Wait!" Ishihara hurriedly interrupted the words of the Black Soul Daoist, and said with some surprise: "Lord Black Soul is so loving, I am really grateful for it, but the Blood Spirit Forbidden is a secret legend of the Evil Soul Island, and I am afraid that it is not good to study it at will, not to mention that I have not learned any evil methods in Xia, I am afraid it will be difficult to cast the Blood Spirit Forbidden." ”

Ishihara is very happy to learn more about the ban, but it can be regarded as a secret by top forces such as Evil Soul Island, and even his own disciples can't teach it at will, let alone outsiders, he doesn't want to attract the pursuit of Evil Spirit Island, and the implementation of the evil law prohibition needs the support of the evil law, although many monks will practice one or two hands of the evil law as a hole card, but this kind of thing is not easy to put on the surface.

"Don't worry, I'll help you solve these things. Looking at Ishihara, who was a little frowned, the hall master of the Hall of Sin immediately dispelled Ishihara's worries and said:

"The blood spirit ban is not a taboo on the evil soul island, this matter I have obtained the approval of the three island lord Tongyuan Venerable, he is the top guest of the evil soul island, and he has the right to teach the blood spirit ban to a monk, and you don't have to worry about the evil law problem, when the time comes, the hall will teach you a "blood sacrifice skill", which is a special exercise on the island to deal with the spiritual blood of sea beasts, and it can also urge the blood spirit ban. ”

The hall master of the hall of sin has been planning for many years, and he has already considered all aspects clearly, but after saying this, he looked at Ishihara with burning eyes, since he has made so many preparations, if Ishihara shirks it again, he will offend him, Ishihara saw this, only thought for a moment, and immediately said: "It's too much to worry about, the hall master has already arranged this matter, and he is willing to listen to the words of the hall master." ”

"Haha, okay!" The hall master of the Hall of Sin suddenly laughed when he heard this, and the Black Soul Daoist on the side also looked at Ishihara and nodded with satisfaction, and for a while, the three of them looked at each other and smiled, very satisfied with today's result.

Next, the Black Soul Daoist immediately handed over the Blood Spirit Forbidden directly to Ishihara, Ishihara read through it slightly, and suddenly opened his eyes to the strange use of the various runes, this gate ban is really terrifying, just practicing the blood sacrifice spirit blood is probably just a simple application, and there seems to be a more frightening development on it, which makes him unconsciously reminded of the "Blood River Divine Skill" practiced by Zhang Xusheng at the beginning, but there is no further content in it, which makes him slightly vigilant in his heart, if he has the opportunity, he wants to take a look at the evil soul island.

However, now for Zhang Zhiping, he still has to stay on Tiangong Island to obtain the island as soon as possible, so he pressed this matter to the bottom of his heart, and the Lord of the Sin Hall was compensating, and he also arranged a new position for Ishihara, the director of the Spiritual Blood Department of the slaughterhouse.

The Slaughterhouse Spirit Blood Division sounds inconspicuous, but in fact it is a lowly and powerful position, which is in charge of the training, storage and transportation of the spiritual blood after the slaughter of the sea beasts in the entire slaughterhouse.

Ishihara doesn't care about being greedy for a little cheapness, what he values more is the authority that this position brings him, so that his movement restrictions in the Sin Hall are greatly reduced, but now the Sin Hall is in a hurry, and the Lord of the Sin Hall has only given him a month to deal with all kinds of miscellaneous things, and after that, he will follow the Black Soul Daoist to work all the time.
