In the Underground training of Ranger's Eye. A human shadow can be vaguely seen traveling from one tree to another without a sound.
This is Fain trying to remove the sound of his footsteps until it becomes completely unhearable. He knew this move would become an asset and increase his chance to kill his enemies quietly. Just imagine sneaking to the back of an enemy without him knowing that someone was approaching. How frightening was that be? Fain prefers instant killing because this style would reduce the risk of getting injured and save his energy. He doesn't want to make his movements too flashy like other people because he knows that only by removing what is useless and retaining what is useful would he become a frightening opponent.
After practicing for nearly an hour he stopped. He wiped the sweat on his forehead and jump to the biggest tree. During the years of fighting the demons, he frequently sleeps in forests to rest. Living on top of huge trees became a habit. Although he knew that the beast no longer pose a threat to him. Who doesn't want fresh air right?
He looked at his surroundings first before meditating. This meditation method was acquired by him by spending half of his contribution point. You should know that his contribution points had already reached a frightening amount due to him cleaning up demons for a year.
As for what are the benefits of this mediation? Well, it helps him hide his aura and lower his presence to a terrifying degree. Even a person stronger than him might not notice him without fully concentrating.
This mediation method has quite a history. It was rumored that this method was the possession of an S Class Assassin who was previously a member of their organization.
This master assassin has a scary record of assassinating one realm stronger than him several times. Unfortunately, he offended many powerful people. A group of Class S Degu Users ambushed him on one of his mission and he died miserably.
Nonetheless, it can be seen how powerful this meditation technique was... Fain was ecstatic after acquiring it.
Now, he had already learned several useful assassination techniques. Fain can enter a state of heightened focus in which he focuses fully on killing the enemy, preventing himself from hesitating. His perception would double in this state and he can even notice an ant fifty meters away from him, there is a sensible difference between his power in this state and his normal state. He called this "Killing State".
Furthermore, thanks to his perfect body control. He can now dislocate any parts of his body in a second. He is now confident to escape any grappling techniques that the enemies in the future might use against him.
He has also created a new technique that truly belongs to him. He uses his speed and precision with the combination of his degu to create multiple afterimages or decoys to confuse the enemy. Now with the collection of killing techniques he learned, his lethality has reached an unprecedented level.
After finishing his meditation. He decided to go to his laboratory to complete the last set of his training regiment.

-Fain's POV-
I am now in my laboratory. In front of me was a huge metallic cabin with messy electric wires hanging on it. This machine is capable of producing 200-1000 volts
Some might be wondering what is this for? Well, I used it for myself and I'm not a masochist by the way.
I proceeded to lie down in the cabin and strapped the available dark belts on it to my waist and chest. This is to prevent me from breaking away from the incoming dreadful pain that comes from getting electrocuted. With this method... My resistance to shocks and electricity would increase. After all, a second is enough to determine the life and death of a person and I ain't taking any chances.
After making sure that everything is ready, I took a deep breath and clicked the lowest voltage. With this, a creaking sound was produced. I felt destructive energy invade my whole body. My body was already accustomed to this low voltage for doing it who knows how many times. I'm only warming up my body preparing to challenge the highest voltage that his machine can offer. Even with my strong will and high resistance. I'm still somewhat uncertain if I can bear it.
In my first trials on low voltage. I lost consciousness five times. Getting electrocuted is not a joke, that's why I am using my degu to cover my internal organs. The principle of this was... I would manipulate my Degu into the shape of membranes that covers the organs like lungs with it acting like a protective layer.
I progressively increased the voltage until it reach the highest. With this, I felt my skin breaking slightly and my hair which was protected by degu preventing it from being burnt stood up like a Super Saiyan. Well except for the yellow hair. It felt like being bitten by thousands of ants simultaneously. Time passes, and every second felt like an eternity for me. I gritted my teeth throughout the process but I felt my consciousness slowly slipping away.
I only felt my vision slowly being swallowed by darkness and I lost consciousness.
...
-Two hours later-
I'm now concocting a violet liquid after passing out. My body was stiff and I'm having a hard time moving it. But it's not without benefits though... I felt this time that after recovering, my body would only become stronger again and become more resistant to beatings.
Well enough of that. After mixing up the top 5 most dangerous and lethal poisons in the glass container. I added another three poisonous herbs that I liquidize in a glass container. A drop of one of these herbs is enough to put an adult bear and elephant on the ground. Now, Imagine it mixing with another lethal poison.
Fain can use this on his weapons becoming more deadly. But the real use of this is for himself.
If someone learned of this they would probably think that he was crazy. Well as a matter of fact... He was. There's no denying it, But for him only by being ruthless to oneself can you become ruthless to others and truly become a strong person in both mental and physical aspects. He believes that someone who can't even bear suffering and isn't willing to sacrifice can't ever hope to control his destiny.
The hidden benefit of suffering immense pain had allowed him to become stronger mentally and have full control of his emotions.
