In the setting of the Book of Demons, it is said that this book is like a computer, ** all kinds of cards, which is equivalent to loading various programs and has all kinds of functions. 【】

However, one of the shortcomings of the computer, everyone who has used it knows, when a software is too new and too powerful, it is likely that the old computer will not run. That's why I mentioned in the setting that the person who can finally get rid of the Demon Book will really have power.

And the setting of the "Heart" series is for this kind of person.

The heart is an upgradable computer, the software is too strong, then upgrade the hardware.

Originally, the "heart" for the protagonist was the heart of an alchemist, but some readers can also see that I have a preference for the undead. So the protagonist has two hearts for the first time...... Well, don't you say there's only one? Oh! I forgot that this is the plot of the fifth episode, and no readers have seen it.

The function of the Dead Warrior's Heart is to create undead equipment, using it to increase the wielder's power. Of course, anyone can use the undead treasures made by the heart of the dead warrior, but these treasures are condensed by the power of death of the heart of the dead warrior, just like if you have 10,000 yuan, you can buy a computer for your own use, or you can give the computer to others to use, but the money to buy the computer cannot be returned.

The Power of Death can only be obtained by looting, and is not automatically generated, and crafting a weapon will reduce one Power of Death unless the weapon is restored to the Power of Death again.

However, the level of treasures that can be created is not determined by the amount of death power, but by the mastery of the core Tunguska magic runes of the undead equipment. The current Wang Lin can only create sixth-level treasures at most, and no matter how powerful his death power is, he can't create seventh-level undead treasures. Because he hasn't mastered the higher runes yet\
