The Dao Of Evolution

"Well to begin training, of course we're going to have to find beings of flesh and blood, it's not really a massacre without victims isn't it little friend, Well lucky for you I know where to find said people at in this evil valley" said the Old Monk

As the Old Monk was getting worked over being able to kill again, Caleb interrupted the Monk with his face looking as if it's about to turn red from embarrassment saying "Well, you see I never had the opportunity to learn any fighting techniques as the second I was unsealed from my pot, I was automatically sent here to find my last component, So wouldn't such a great master such as yourself teach me a few?"

"So what you're trying to say after reaching such an age you haven't learned a single thing from your master, that means you're a blank slate" said the Old Monk who was visibly shaking with excitement

"At first I thought your Qi channels and constitution would be shaped for another body refining art but it looks like it's this Old Monk's lucky day, I suppose I can start you with a couple of simple techniques"

"But first I must reshape your Internal Qi Channels to be able to practice these techniques" explained the Old Monk

With a quizzical look Caleb was thinking "Well I wonder how is this Old Man even going to do this?, he's just a ghost what could he possibly do?"

As Caleb was sitting there Unbeknownst to him inside of his Dantian the Old Monk revealed 1 finger and on top of that finger was a red wisp that was exuding the smell of metal, with a vicious aura coupled with it, with a flick the wisp left Caleb's Dantian and started cycling through his meridians, forcefully expanding and hardening it's walls while twisting their path to suite it's natural course.

At the exact moment outside of his Dantian right when the wisp left the Old Man's finger Caleb was hit with a wave of intense pain it was if his veins were injected with molten magma slowly corroding his insides. Slowly yet steadily the boiling feeling in his veins started cycling throughout out his body, each cycle gaining as much intensity, doubling the pain, making him convulse on the ground and slam his head against the rock outcroppings of the cave. But as quick as it came it disappeared leaving a cooling feeling that refreshed the swelling channels and solidifying them, the Qi Channels were left wider and stronger able to hold Vigorous Qi flow, and withstand higher pressure.

Wiping the sweat off his forehead and then holding the back of his head where a bit of blood was trickling, Caleb shakily stood up and gained his bearings, his whole body ached and everything was flaring with dull pain.

"Old Man, what did you do to me" Caleb shakily said with anger veins were popping out his head out of frustration from the sudden lapse of pain.

"Steel yourself brat, I reshaped your Qi Channels with the remnants of my Fiend Blood Aura, you should be thanking me, this is a once in a millennia opportunity" berated the Old Monk

Standing up and feeling out the changes in his own body Caleb noticed that his body was indeed stronger, and he could feel that he could hold more Qi than before. He noticed that his Qi contained a sort of ruthless attribute that it didn't have before besides it's natural toxicity ingrained from the sealing.

"Now that you have refined your body it's finally time to pass down my long lost arts......"
