The Lightning Flash?

(Ima make this a quick chapter cause I am tired, so I named it Lightning Flash)

I wake up in a strange place, the area is cold and lightning flashes occur around me. I remember the sword knowledge reward and decide to use it.

'Do you wish to use Mortal Sword King Knowledge pack? Yes/No'

I choose yes.

'Would you like the slow version or one second version? One/Two'

I guess i'm pressed for time here, I choose option two!

I feel something forcefully entering my brain and I feel a heart wrenching pain in my head. I curl into a ball and try to suppress the pain but don't succeed…

1 hour later…

"Thank god its over" I mutter to myself, praying to the few gods I know. I stand up and take out Heaven Betrayer, my white sword with the ability to gain demonic powers for a short while, and enter one of the strongest stances in learned, Black Flame Stance.

I execute this to the best of my ability and find that the "Raging black flame" is only a small flame on the tip of my sword, It appears that I will need to practice all of these abilities…

I instead enter a much easier stance, but it is still very strong, it is called Jōden-no-kamae, I believe it is also known as the fire stance, it is from Kendo… Whatever kendo is…

I raise Heaven Betrayer above my head, and move my feet to the right positions.

My aura suddenly manifests a physical form, it becomes a light red mist that surrounds me.

It appears I got this stance correctly…

I begin practicing my swings until I feel I can execute them accurately. I begin to move from my position, which appears to be temple ruins, one small in size, short stubs of pillars remained, rocks and debris everywhere.

I spin around and immediately enter Jōden-no-kamae to defend myself, but this being is to fast.

I realize I should have practiced a defensive stance… Damn you author for not giving me enough time or remembering that you should give your character some plot armor… or at least a defense move…

I attempt to block the attack but it seems to flow away from my block and goes under my sword, I channel my mana and make a small shield where the strike would land and I get blasted across the plains. I smash heavily into a rock, coughing up blood as I attempt to stand.

'Host is in near death state. Would you like to gain the power of god so you can defeat your enemy and survive? It costs half of your life. Yes/No.

I select yes…

I feel an immense amount of power enter me and something else… Experiences? I know how to use my techniques now! Yay!

I refocus my attention on the speeding lightning bolt, I enter the most powerful stance I have, Gods Gift. Yes, its called gods gift, but it is called Gods Gift because 100k years ago a man was betrayed by his family and friends, he picked up his sword to kill them but something stops him and draws him towards a nearby temple. The temple was made for an unknown god, but it had the symbol of a God, a Devil, and a Dragon. The man walks up to the statue of the God and prays, then to the Devil, and then to the Dragon. The man walks out of then temple with the strength of a dragon, the wits and cunning of a devil, and the knowledge of a god… But MC don't know that, so don't tell him.

As I enter the Gods Gift stance, I feel everything around me slow down, the lightning bolt in the distance slowing to a halt, I use a movement technique called Dance of the Devil and I instantly arrive in front of the lightning bolt, which turns out to be a girl, of course.

I use a attack technique called Dragon's Claw, it hits her in the back causing 5 bloody gashes, and sending her flying into the rock face I was sent to, unfortunately for her, she hit with enough force to create a cavern if she didn't splat, which she did create a cavern.

I use Dance of the Devil to appear directly in front of the girl, her eyes closed, suddenly, I feel all my strength leaving me and I fall on top of her, quickly asleep from her squishy body, though her figure is lithe. While I am asleep…

"MUAHAHAHAHA, I HAVE RETURNED!" A strange voice sounds out, though silent to everyone but itself. "Wait, I am a sword now? At least I keep my title…" Behind Janus, Heaven Betrayer is flying around and around and…
