Travelling Asgard is best thing i had done in both of my lives.Seriously this place is so beautiful that it makes me sad that it will get destroyed maybe i should change this, lets leave this thought as a note to myself.
Fun fact about Asgard:It has edges and an end unlike Earth,if you fall off this edge you will literally fall in void(space) so you have to be careful.
Well training for me was easy as i never did break any bones but at most got tired out. Tyr was shocked and sad at this.I think he was a sadist who liked to inflict pain on others as he kept on increasing my training difficulty with time.
Time Skip about a Decade
In this decade i spent with Tyr he taught me everything thing he knew and trained by body.He tried to make me buffed up but na i said no. Though i have six pack abs and can throw quite a punch i have a quite athletic body.In this Decade i learned a b.a.r.e handed fighting style and how to survive in the wild along with some alchemy and a bit of magic.Tyr was shocked to see my talent in magic and alchemy and told me to pursue them later on as he only knew the basics of them as he didn't have big mana pool.
"Carl i have taught you everything i know even though i myself can't believe how can someone learn my life experiences in such a small amount of time.For now i have nothing more to teach you,from now you are to travel on your own and gather experience though you are quite a good fighter don't forget that their is always someone better and to reach their level you constantly need to develop"
"I Understand" said Carl
"Ok Carl now i have a question to ask you,even though i have taught you everything i know would you acknowledge me as your Teacher?"
"Yes sir"
"I should tell you that i have nothing more to teach you and an Asgardian can only have 2 formaly acknowledged Teacher, so still would you become my apprentice and share my burdens?"
"Yes sir,you have taught me alot and helped make the man i am now"
Tyr makes an incision on his hand from which blood pours out.
"Good,then do you Carl son of Asmund acknowledge me Tyr Odinson,Asgardian God of War as your Teacher and willingly become my apprentice?"
"Yes i do"
Lighting crack as i make this oath and Tyr drops his blood on my forehead.
And from hereon i am Carl Asmund Apprentice to Asgardian God of War.
