The Witcher: Son of the Planes.

“When you were still young, I never told you about it, so you didn’t know the significance of the Book of Cain. Now that we are at this point, I will briefly tell you about this book.

The Book of Cain is the secret book of the blood race created by our ancestor Lord Cain throughout his life. It records all the spells of our blood race. Unlike the black magicians in the parliament, in addition to conventional magic, it also has some secret arts of our blood race.

After Lord Cain created this book, it has been kept by every most powerful blood prince. With the iteration of the blood clan and the establishment of the Dark Council, it has gradually been kept by the Speaker of the Dark Council.

And the Speaker has never been lost to our blood clan. No matter what the current Demon Party, the Demon Party, or the neutral clan, they have all taken turns to control the power of the Speaker.

This resulted in the thirteen clans basically controlling the Book of Cain for a period of time, and everyone had more or less selfish motives. Up to now, except for a rule that only clan leaders could read the Book of Cain, the Book of Cain has spread to all the thirteen clans.

Although I don't have the original copy now, I have a copy in my hand. But your request is too important. Besides, Snape doesn't have the blood of the vampires, and he may not be able to practice some of the spells on it. What's the point of taking it? You don't want to give it to the church, do you?"

"No, no, Grandpa, Snape is not from this world at all. He just likes to delve into some strange things. As long as it is something he doesn't understand, he wants to know about it.

According to him, it was the pursuit of truth, and he promised me that after obtaining the copy of the Book of Cain, he would find a chance to leave the Twilight Plane.

The chance of meeting him in the future is very slim, and other clans won't know anything. Grandpa, I have already signed a contract with him, and my freedom depends entirely on you." Beit requested again.

Bruya looked at the grandson of his eldest brother in front of him. He had caused trouble hundreds of years ago and he had to expel him from the country. He thought he was dead, but he didn't expect him to come back hundreds of years later.

His return made his cold heart warm up. After all, he was his closest direct descendant. And now Beit's request would be another earth-shattering event.

For Snape (Colin) who left this dimension, it might be read as a new knowledge, but for their thirteen clans, it was just giving away the secret treasure, and in such a "semi-coerced" way.

Forget it. I am old now. I don’t know whether I can survive after this holy war. I don’t know how to use the Book of Cain after the next generation of patriarchs get it. It’s okay to make a copy for Beit in advance. Even if I don’t live a good life in the tribe in the future, with the Book of Cain in hand, I may be able to make a comeback. It can also be regarded as leaving a seed for the Bruch clan.

Thinking of this, Bruya felt that he could not let Beit stay in the tribe any longer. If he stayed in the tribe, he would have to fight with the Church of Light. It would be better to let him hide and wait for the end of the holy war. He could just find an excuse for a mission and not worry about sending him out.

"Okay, I agree, but I also need you to agree to one request of mine." Prince Bruya said.

Why do you have to make demands? Can't you keep it simple? The eldest brother is like this, and so are my uncles. Am I the only one who is heartless?

"I can give you the copy of the Book of Cain, but you must promise not to reveal any of it to anyone except Snape. After you leave the family, don't come back until the end of the holy war. You must stay away and don't get involved in any disputes between the Church of Light and the Dark Council."

"Grandpa, I am also a member of the Bruch clan. How can I escape from the war alone? I won't leave!"

“Shut up. The Book of Cain is very important. I can’t guarantee that I will survive this holy war. You have to survive as the seed of the Bruch clan.

If the Bruch clan declines in the future, with you and the Book of Cain, they can rise again. Do you understand? If you don't agree, the matter of copying the Book of Cain will be abandoned."

"Uh...Okay, Grandpa, I promise. Please take care of yourself. The Bruch family still needs you."

"Okay, you take a night's rest first, I'll give it to you tomorrow. Remember what I said, after you leave tomorrow, don't come back, stay far away."

……

The night passed quickly, and when Prince Bruya handed two copies of the Book of Cain to Beit the next day, Beit understood the deep meaning of his uncle's words and could only leave the family home in tears.

After returning to the city of Kemia from the tribal land, through the special induction between the two, Beit quickly handed the rubbing of the Book of Cain to Colin.

"Boss, when are you leaving?" Beit asked.

"I'll leave as soon as possible. Why are you in such a hurry for me to leave?" Colin joked.

"No, I am leaving too. We don't know how far this holy war will go. My uncle asked me to leave early and come back after the holy war is over."

"Well, your uncle's consideration is correct. He wants to preserve the manpower and try to make a comeback. If the war goes well, you may not even need this backup plan."

"I hope so. Take care, boss."

"You too, I hope that next time I come, you will have grown into a great person, so that I can benefit from your fame."

"Haha, okay, thanks to the boss for his good words, I should also work hard. Let's go, let's go."

After Beit left, Colin quietly flipped through the Book of Cain. The Book of Cain had a strong smell of vampires.

The first chapters are very conventional, similar to the witchcraft books I have seen before, all of which are explanations of some magic and other spells. Some spells also involve some knowledge of rules, but they are rare and not very thorough. (After all, Cain is just a powerful demigod.)

Turning to the back, there are more obvious changes.

Especially the secret techniques mentioned later on how to use the blood of the vampires, which aroused Colin's interest.

At the same time, the following content also made Colin understand why the Book of Cain was so important and was only passed down to the patriarchs of the blood clan.

Because of these secret techniques, the Book of Cain is called the secret book of the vampires.

Although there is a lot of content and various methods in the following part, Colin did not take other methods seriously. Only two secret techniques are very meaningful to Colin even though he has read tens of millions of books.
