Hero of Darkness

Kahn officially acknowledged Romulus as his master after hearing his plans. 

There was no shame in accepting the truth about someone mentoring you becoming your master in all senses. 

Because the one who does not respect their teacher can never truly learn from them in the first place. 

Now, it was time for Kahn to start his training for real. 

First, he tried to understand the basics of Harnessing explained by the peak 7th stage saint. 

Like the word implies, one must 'harness' the world energy. But it wasn't just as same as absorbing it. Rather, refining it using your own body as a medium and then elevating it to the next level. 

And then use it to incorporate into their attacks. 

What Kahn got wrong the first time during his attempt was he only formed a layer and let it touch his body without having formed the ability to refine that world energy acquired from the outside source. Which resulted in two different and incompatible forces of nature, the world energy stored in his body and the one from the environment that he was forcefully controlling, colliding against each other and causing that explosion; resulting in his forearm exploding. 

His body needed to go through this procedure and only then he'd be able to use the same amount of world energy like Romulus and stack over a hundred layers of it as the wolfkin did. 

"First we need to change how your body processes world energy." said the heavenly king as he folded his arms with a somber expression. 

"How?" asked Atreus aka Kahn. 

"By draining it down till there's nothing left. 

And then I will use a form of technique to restructure how your body circulates it and also make it flow more rapidly inside your body such as through veins and the nervous system. 

But do know that it will be extremely painful. 

And you will feel like you're being pierced by millions of sharp needles in every inch of your body." he revealed the painful experience that was to come beforehand. 

"The only thing that can become a hurdle is your inability to withstand both mental and physical pain. 

Well… You can withstand it given your regeneration abilities and bloodlines. 

The problem is your mind will give out soon." he spoke with a face full of concern. 

"So now… Fight against me first and show me your strongest skills." ordered the new master.

5 Hours Later. 

BOOM!! 

Inside the pocket dimension they were training, Kahn was going all out. 

He used the new Asura Mode which now contained Cthulhu's regeneration abilities and resilience against many elements. 

Then, he also simultaneously used the Shura Mode, forming a half-a-kilometer tall phantom this time. 

This was his most world energy-consuming skill if Kahn didn't use Rathnaar's core to use as an auxiliary source of world energy. 

However, both Kahn and Romulus didn't acknowledge it as his own because the system created both of these modes of battle forms and not Kahn himself. 

And exactly when he was on the last straw, Kahn used Berserk God Mode after 2 years again. 

During those 20 minutes, he was comparable to an intermediate 5th stage saint. 

However, no matter which skill or attack he used, Romulus' defenses were unharmed. 

Even the Dimensional Cut skill couldn't cut through a red barrier he summoned as the wolfkin only received the attacks and did not fight back at all. 

Kahn didn't know what kind of skill or techniques the peak 7th stage was using… But even his strongest and sure-shot killer move no longer worked. 

And if it didn't work against the wolfkin, means many other powerful saints with unique abilities and skills could also remain unscathed against Dimensional Cut. 

In a way, Romulus was many times better and more powerful than any of the Mythical Rank monsters Kahn had faced till this point in Vantrea. 

But thanks to this experience, he became aware of how powerful this world was, filled with people that could even find ways to nullify the divine abilities of a chosen Hero. 

[No wonder Rathnaar was able to kill so many heroes despite having no divine abilities. 

They can be countered if you have the correct methods and skills prepared.] thought Kahn as he finally expended all of the world energy in his body as the activation time ended. 

His body was now full of sweat and he dropped on the ground, panting heavily. 

"I can't move. Hell… I can't even breathe properly." he said with an exhausted countenance. 

"Good. 

Now let me open your world energy pathways and force out any remaining reserves." said Romulus. 

He put a palm over Kahn's head and the very next moment… 

Splat! 

Thousands of small pores opened on his entire body and Kahn's blood was expelled out. 

"You have too many bloodlines. Some of them even counter each other. 

You're lucky that you have a Mythical Rank Metamorphosis Bloodline as well. 

Otherwise, it wouldn't have balanced out the rest of the powerful bloodline at this stage. 

Your blood itself could've been turned into poison and deformed your body and mind, eating it from the inside." he warned Kahn openly. 

[It's just like Argos says… His Divine Abilities will kill him soon. 

I can only cleanse some of the toxicity for now. I will have to leave the rest to him since my knowledge of bloodlines is just superficial and he's a true expert in them. 

This brat… His luck was too good to not have died till this point. 

The question is why did the God of Darkness allow him to choose these divine abilities despite knowing the consequences?

Well, that's not my problem. 

I can help him to live for a couple more years by doing this. Argos can take care of the rest.] thought the wolfkin. 

Kahn's blood churned and as Romulus said, he felt like being pricked by millions of needles in every inch of his body. 

Tears dropped from his eyes as Kahn felt like his skull, skin, spine, bones, arteries, veins and entire nervous system was getting demolished, ground, shattered, and torn from the inside. 

Every passing second felt like an eternity and in those moments, he felt like dying dozens of times. 

This was a pain that would make someone faint on the spot but Kahn's quivering yet unwavering figure revealed his unyielding and indomitable will. 

Hours passed and now the floor was covered in liters of black blood. 

Finally, all the smudge and blood turned into ash under the fire released by Romulus. 

[This kid is good. That type of mental fortitude and perseverance… Even among saints, there are less than 15 people in the world who can withstand such pain without going mad. 

I can't say about strength but as far as mental capacity is concerned…] thought the Apostle of Slaughter and gave his verdict. 

[Kahn is definitely the strongest one among all the new Heroes.]
