Ren reached home while thinking about Jack. He rang the doorbell and his first victi... His step-mom opened the door. He smiled at her and went in. She smiled back. He said "I am home."
She replied, "Welcome home~~"
Then he went up to his room and got changed. Obviously, he hadn't checked out the day's gains nor had he learnt the techniques. So he wanted to learn the techniques first. He took out the hypnotism technique and started reading it. He read a few pages and saw that it wasn't easy to do. So he stopped there and thought for a while.
'I should learn the quick technique first since it is easier. I can also use the time it gives me to practise the real technique properly.'
The Quick technique was very easy to learn. He spent a few hours on it that day instead of m*st*rbating. Yui came into his room in the middle but saw him "studying seriously" so she left while thinking that it was odd. She went to a different all-girls school which was farther away so she took thirty minutes longer than him to reach home.
By dinnertime, he had gotten the hang of it. At least that is what he felt. So he looked at the other technique. It was a physical strengthening technique which required years of foundation from a young age. Fortunately, the serum would help him bypass that need. He wanted to take the serum immediately but he remembered about all the online novels where such a serum takes a while to act and then the impurities in the person leak out so he thought better.
This was usually the time he would write his diary, but then remembering what his descendant said, if he wrote his diary, somebody else in his current timeline's future might see it and maybe ruin his life, but he also felt like his future "adventures" deserved to be documented. It was too much to deal with right now, his hands were full trying to get control over his immediate family first. He would think about these things later, once he could control everyone in the house.
He went down to eat. On the way down, he met Yui who frowned at him. He smiled bitterly at her while thinking that it would not be long before she would be on her knees in front of him.
They sat down for dinner and Mei was already there. Mei had reached just an hour ago from her part-time job. Although their father was quite rich and they didn't need to work for a living, more money was always better or at least that's what she thought.
Mei smiled at him and started eating. Ren smiled back and ate his food. They chatted a bit, while eating. Then he went back to his room to read the Quick technique again so that he could be better at it. Then he went to sleep.
The next day, he got up earlier than usual since he was hyped for the first use of the technique. Only his step-mom was awake at this time. So he went down to the kitchen and had a glass of water. Hina was pleasantly surprised that Ren woke up early that day. So she asked him the reason.
Ren replied, "No reason particularly, I just wanted to be more fit. So I got up early to do some workout."
She went back to her work. Ren went up to her while hesitating slightly. He called her and said, " Hey can I do show you something really quick?"
She nodded. He quickly executed the technique and checked whether it worked. He saw that her eyes had glazed over and she wore a vacant look on her face. He mentally did a guts pose and became happy. He told her, "Hina, you will hug me till I tell you to stop."
She obeyed. He felt her big, soft boobs on his chest. His nose almost bled. He became ecstatic. Then he remembered that it lasted for a few minutes. So he made her let go of him and ended the technique. The technique required a bit of his brain power so after it ended, he felt a slight headache at his brain power becoming depleted. He expected it since it was written in the book. He went back up to rest for a while but changed his mind upon remembering the serum.
Ren went to the bathroom and prepared the bath. He took off his clothes and grabbed a towel. He entered the bathroom and took the serum. He didn't feel anything for a few seconds. Then he got knocked out. he woke up a few minutes later smelling a bad repulsive odor. He immediately took a shower and entered the bath while feeling the changes in his body. He was astonished. His little brother was not so little any more. It had almost doubled in size. Although his pen*s was not that big before, it was still average size. But now it had become 8" long without being erect. That was not all. His skin became softer but elastic. It became fairer too. He grinned happily thinking about this.
He looked in the mirror and saw his blue eyes and black hair. He had become a bit taller, just barely noticeable. He felt amazing. He felt like he could lift a car, not really but still he could probably lift two grown men at once, easily. He exited the bathroom and put on his clothes. He took the serum vial and went to his room. He then remembered about the space ring. He got a glass of water from the kitchen and put the ring into it. He didn't think that it would really dissolve but it did. Then Ren drank it. It felt a bit bitter. He was knocked out again and fell on the ground. He woke a bit later with a massive headache. He felt weird. Then he saw a tattoo on his right wrist. He thought about it and sent his awareness towards it. But nothing happened. Then he thought about the "Brain power" that was in the technique book and guessed that he must use that. He tried to use it but he felt a slight pain. He tried it again and it didn't pain as much as before. He tried to send it to his right wrist. It was easy but slow. His meager brain power couldn't do it fast. Just focusing on his right wrist while using the brain power sent it towards his wrist.
After a few moments, it finally reached his wrist. and suddenly, he saw a screen in front of him which showed a list of the items in his inventory. He could currently see only 50 items. He felt scammed but then he remembered that a higher brain power must be required to access it all. He felt weak. He looked at the list again but properly this time. Half of it was medicines of various types. The rest of it had supplements for his growth (since he is till a teenager) and potions to keep his little brother erect for longer. The descriptions for the items were on a label on the respective bottles. Ren smiled deviously looking at the last type of item. He was thinking about using it.
Then Ren started studying the Martial technique since it was still early for breakfast. He read the introduction and felt like practising it would be a blessing and he became excited. He saw the methods in the first part of the technique. He tried it out and felt some slight pain in his body but it wasn't much since he had taken the serum already. He practised for an hour and went to have breakfast after Yui called him out.
