Chapter 78: Using the Potion.

After making the deal with Mr.Dealer, Felix walked out of the house and followed the grey-robed man who revealed a hidden way of leaving and entering the underworld to him.

They made their way to the boundary of the underworld reaching a place where there was not a single person in sight.

Arriving at the farthest wall, Felix saw a similar black curtain attached to it with a person guarding there.

The gray-robed man approached the guard and handed him a few coins before calling Felix to follow him.

Felix nodded and walked behind the man as the guard opened the curtain and let them enter inside.

They made their way upstairs for some time and walked out into a dark room.

The gray-robed man opened the only door of the room and motioned with his hand for Felix to exit.

Coming out of the room, Felix glanced around and saw himself appearing inside the corridor of some tavern.

He looked back as the door closed and remembered the room number.

'Who knew the way into the underworld would be hidden in a random room of a tavern....'

While giving his surroundings a surveying look, Felix went to the stairs and walked downstairs to the lobby of the tavern.

He had not yet removed his mask, so when he entered there, a lot of people turned to look at him.

But strangely none of them showed a reaction and continued with their work as if it was a daily occurrence.

Felix didn't waste time doing anything there and walked out of the tavern before turning around and remembering the place.

'All of them were part of the underworld, that's why they didn't react when I walked out wearing a mask. From now on, I'll better use this place to travel in which is much better than those unguarded manholes.'

He decided and started walking away from the tavern into the streets making his way back to the guild building, while taking out his map to find the directions there as the sun slowly hid beneath the horizon.

.....

When Felix arrived at the guild building a few minutes later, he showed his card at the entrance and entered inside as the door opened with a slight glow.

He poked his inside the hall and glanced around to see if there was anyone present at the reception.

'Uh-oh, there's Miss Elsa.....'

He saw a blonde beauty staring in his direction with a small smile on her lips.

Felix couldn't help but take a gulp and release a deep breath to calm his beating heart as he was going to lie his way in.

'Alright, let's go!'

He was feeling more nervous and scared at the thought of lying to Miss Elsa than he was when fighting in the underground battles with those big guys.

Making his way over to the reception, he greeted her with a casual grin on his face.

A few seconds later, he suddenly shivered at the abrupt explosion-like feeling inside of his body.

The eyes which were closed for meditation shot open as his internal body felt like burning to the extreme.

From his mouth, throat, chest, and all the way to his stomach, he felt a powerful reaction going on which made him feel uncomfortable.

'What's happening?! I'm suddenly feeling so hot!!'

Taking a deep breath which hurt more than it relaxed him, Felix remembered what he had to do after drinking the potion, and instead of worrying about the pain he was going through, he turned his attention back to meditation.

Using the meditation technique given by the guild, he focused his mind and took the rhythmic breaths, and controlled the energy inside his body to move in a loop all around his nerves.

"Ughhh!!!"

Even though the pain was making it hard for him to keep a conscious mind, Felix remained determined and bit his lips until it bled to make him remain focused on the situation at hand.

All the energy and the power from the potion moved around his body along with the meditation technique's rhythmic breath and slowly integrated with it making its way into the various pulsating nerves.

"Kuhh!"

Felix coughed out black blood the moment the potion's energy and his breath in the nerves completely joined together.

Both of the energies interacted with each other and started fusing together making his veins slightly pop out and tremble all over his skin.

His body started to slowly release black color sweat and steam while he grits his teeth to continue meditating.

After some amount of time, there was no energy left to be fused and every nerve inside Felix's body appeared stronger and thicker than before.

Taking a deep breath and letting it out slowly, Felix opened his eyes.

"Haaa that was exhausting...."

He stood up feeling the new strength inside of his body, but before he could test that he felt the dirty and sticky black sweat on his body.

"Well, another bath it is."

Walking off, he quickly entered the washroom and cleaned his body.

And while doing so, he marveled at the overall change that the potion had brought him.

"Fucking hell, my muscles got bigger and I also got a bit taller!"

He turned his eyes down looking at his little guy that towered above his belly and stood straight like a sword pointing toward the heavens.

"It seems I'm still full of energy, huh.", he grinned and quickly ended his bath, coming out from the washroom.

"Then let's go release all this energy....."

He quickly wore his clothes and walked out of the room, heading to the training room on the second floor along with his weapon.
