Relic

A few seconds pass and Fisk's body catches fire with white and black flames. The flames burn the body in seconds leaving only ashes and a small object  in the middle.

I walk over to the the ashes and shout " Oh my god ! It actually worked !" I stare in wonder at what's on the floor among the ashes.

A pure white crystal with some blue streaks on it is on the floor. I slowly squat down to the crystal that seems to be shining and pick it up. I conjure a small array to examine the crystal more closely .

It seems Fisk's life energy had been converted to pure spiritual energy !

Who would have guessed Fisk would be this useful in death than in life.

I am honestly surprised it worked at all. The blue streaks in the crystal seem to indicate some kind of residue that is different from the rest of the crystal. 'I wonder what they mean' .

My relic is seriously overpowered. I was worried that it was going to simply kill him. I wouldn't have been too broken up about it if It did, but I prefer this outcome.I can use this crystal and refine it to increase my abilities .

I had a vague idea about what I wanted to do and I guess I succeeded. My mind goes to what the Ancient One had told me about this relic. Which left me flabbergasted and honestly a little excited.

The sword of yin and yang also known as the sword of Pangu also known as the sword of life and death.

It is said that a primordial god named Pangu used this sword when he began creating the world. He separated yin from yang with a swing of his giant sword, creating the earth (murky yin) and the sky (clear yang).

To keep them separated, Pangu stood between them and pushed up the sky. 

In theory since all life consists of yin and yang it should have the ability of creation and destruction. It also possesses the ability to cut and absorb an opponent's physical or spiritual energy.

It can then use these energies to temporarily boost the wielder's abilities either by supplying yin to boost mental powers or yang to boost physical powers.

The only downside is that when the sword takes these energies from the wielder's opponents their opponents are severely weakned and may even die. Normally that would be a good thing but I can't arbitrarily use it against normal people .

Normal base humans don't usually have a large amount of spirtual and physical energy. The sword also has the ability to slowly gather these energies passively from heaven and earth, but it is much slower and it takes a long time to recharge.

The ability I just used was something I thought about, but didn't know if it would work.

I mean instead of temporarily boosting my abilities what if I can crystallize the life energy into different kinds of crystals that contain different types of energy.

The sword can naturally produced these crystals once or twice a year. These crystals should be theoretically more powerful than the one I just made. As it is directly refined from energies absorbed from heaven and earth. The sword also has the ability to kill gods and other mystical beings and absorb some of their energy .

It can also shrink and enlarge according to the wielder's preferences. When I heard about that particular ability from the Ancient One I was excited  to say the least. It's powers are so bullshit I almost don't believe it exists .

The Ancient One warned me though to be careful when wielding the sword and to wield it with absolute clarity of mind.

Because it can easily go out of control and devour my own spirtual and physical abilities. It's a powerful relic with its clear advantages and disadvantages. I am pleased with it and I also suspect the reason why it chose me and the reason I felt a connection to it is because I transmigratted from another universe.
