Miles took the train and went home. He was feeling giddy and satisfied and didn’t want to do anything for the day. He took a shower and laid down on his bed. As he was going to Portal World every day, he was also getting stronger. Without him knowing it, his strength was increasing rapidly with every fight. In no time at all, he would once again be limited with his human body, and he would have to take the third serum.

Strengthening Serums weren’t only causing pain, but had lots of side effects when used irresponsibly. In Miles’s case, thanks to his strong will and strong body, which was at its limit, he only felt unbearable pain. But if he used it without capping his attributes, he might be paralyzed or even die.

That was what made it scary. People with superpowers, even when they were weak, had endless potential. They could get stronger just by relying on their superpowers and wouldn’t risk their lives. People with superpowers hardly used serums to get stronger before making sure it wouldn't cause them irreversible damage. That is why Miles got so surprised when he saw the Elfrun, despite her strong superpower she had used the Strengthening Serum.

But it didn’t mean he was safe as long as he capped the attributes. Serum mortality would increase with every usage. No one had ever used the 4th Serum when they were in Grace-Rank. But when people got into Form-Rank, they would use the serums more often. Miles didn’t know why before but now understood that it was because of energy. Energy probably somehow allowed people to alleviate serum’s side effects.

But Miles was different. He had no way to level up without making use of the serums. Since it was so, he could only take the risk.

Miles succumbed to tiredness and fell asleep.

The next day, Miles left his house and went to the military headquarters once again. At the entrance, the soldier had scanned his AI and saluted him when he saw the name. “Welcome, sir!”

“At ease,” Miles said with a sigh.

“Do you want me to inform the General or Major General?” Soldier asked.

“No need. Please continue your duty, I will look around.” Miles said and walked away.

“Yes, sir.” The soldier saluted and went back to his guarding duty with zeal.

Miles blended into the crowd and walked towards Evelyn's laboratory. At the entrance, he saw a smiling fat man. “Hello, Uncle Roger.” Miles greeted as he approached the guy.

“Hoho, Miles. You have grown up so much. Come, let me take a look at you!” Roger said to him while smiling. Miles walked and sat next to him. Roger looked at him and concluded. “Good physique. You have used the second serum right?”

“I did,” Miles answered but didn’t say he was almost ready to use the third. He didn’t tell his family, yet, so he wouldn’t let others know it either. After all, third and fourth serums were ever more dangerous. He didn't want his family to stop him.

“Oh, you are not bad indeed. I always knew you would use it.” Roger said and let Miles go. “Evelyn just left for lunch. She should be in the cafeteria.”

“Thanks, Uncle Roger,” Miles said and left the laboratory. He moved to the staff cafeteria. He knew the building like the back of his hand, thus found the place immediately. There was an id scanner at the entrance to keep irrelevant people out. But Miles practically lived here when he was small, so Coin had entrance access. That was why Roger sent him alone.

Miles walked to the door and scanned Coin. The door swished open, and a boisterous cafeteria came into sight. Miles looked at the line and noticed there weren’t many people waiting, so he decided to grab something to eat.

As the highest-ranking food court of the headquarters, the foods were all top tier. Miles walked to the line and picked burgers and fries with onion rings. For a drink, he ordered a coke and looked for Evelyn. Miles noticed the beautiful lady reading something on her wrist watch while eating fries gracefully and walked up to her.

“Hey beauty, can I sit with you?” Miles said as he stood next to her table.

“Move along if you like to have a peepee,” Evelyn answered tersely, without looking at him. Miles sat across helplessly as he waited for her to look at him. After realizing the person hadn’t left and dared to sit, she raised her head to look and saw Miles.

“Was it you, Miles? Hmph, you are old enough to tease me now?” Evelyn said with a pout.

“I just said hey beauty. You were the one misunderstood.” Miles smiled and answered.

"Alright, you are a smartass too," Evelyn said as he looked at Miles from head to toe. "You look healthy at least."

"I am doing fine, mom." Miles wanted to throw a tantrum now that Evelyn acted like he was a kid. "

"Fine my ass." Evelyn wanted to berate but then got quiet.

"You are keeping an eye on me, right?" Miles asked with a smile and felt warm in his heart.

"Pierce in your leg, how did you get it?" Evelyn asked. It wasn't strange for her to know it, after all, Miles had it checked up in a hospital.

"From a person who can never see the sunlight again," Miles answered as he ate his food.

"Good. Anyone who hurts my son should be buried 10 meters under the ground." Evelyn nodded in approval. It wasn't strange nor cold for her to say this. After the monster invasion, humans learned how to harden their hearts. Without the will to hurt monsters or more dangerous creatures, humans, hunters would be monster poop long ago.

They talked as they ate. Then, they walked back to the laboratory. There, Miles would use the Mind Serum.
