"185...190...198...200"

After finishing the push-up, I felt exhausted, so I sat on the floor.

"Regret, give me water."

"Hmm. Gulp gulp gulp."

She took water from the system's storage tank and drank it, then fell to the ground. It has been nearly three and a half years since I was reincarnated.

I am now twelve years old, and I will turn thirteen in February, next month.

Over the past three years I have made many changes, the most important of which is that I have continued to train my body, and my body has become as strong as an adult's body.

You may think that my strength is weak, but even though I am twelve years old, this is an achievement. I don't want to brag, but my muscles have become a piece of art.

My relationship with Komachi has developed a lot. Whenever I go to bed to sleep, I find her standing in front of me and saying with her puppy eyes.

"Onii-chan, let's sleep together."

And I am a good big brother. How can I refuse the request of my cute little sister? One day when we were playing together outside, she promised me that when she grew up, she would marry me.

The rest of my relationship with my mother remains the same: she respects my privacy and only intervenes in important decisions But on the other hand, that old bastard started treating me harshly when he heard that Komachi promised to marry me when we grow up.

As for how to know this, the reason is very simple. When we came home from playing outside, Komachi went to my mother, who was preparing dinner, and said:

"Mom, I'm going to marry Onii-chan when I grow up." The old bastard was sitting on the sofa and reading the newspaper When he heard that, he tore up the newspaper and looked at me with looks that made me shiver. Looks can kill, and they have killed thousands of times. At that time, hiding behind my mother saved .

<Master is ready to absorb mana essence>

Hearing the system alert has saved me from diving into the past. I stood up, took some clothes and went to take a shower. My clothes were full of sweat.

"System How can a absorb heart mana?"

<The heart can be absorb by sitting, placing the in your hands, crushing it, and focusing on exhalation, inhalation, system will help master to accommodate heart.>

"Pzz..."

While I was sitting in the bathtub, I asked the system how to absorb the core. When I heard the answer, I sat on the ground and took the heart out of the system's storage. I closed my eyes and began to focus on inhaling and exhaling. Then I broke the heart by pressing it with my hand. I heard a breaking sound similar to the sound of breaking glass.

<The process of absorbing the mana core has begun>

<00 100>

<1 100>

<... >

Even though my eyes are closed, I can still clearly see the system notifications.

When I started sucking the heart, I felt as if something was moving from my head to my feet and then back to my head, and this cycle continued.

I began to feel as if my body was getting hotter and something was coming out of my body. I smelled a disgusting odor, and it was difficult to distinguish the source of this odor. Despite this odor, I continued to focus on my breathing, and as time passed, an hour...two hours began. I feel as if my body is burning from the inside and outside

Even breathing felt like hundreds of knives tearing through my lungs, yet I continued to endure this pain. Then the pain suddenly stopped, as if there was no pain, and the system notification appeared.

<The process of absorbing mana essence has been completed>

When I saw the system notification, I took a deep breath, sighed, opened my eyes, and the first thing I noticed was the black and gray matter spread around me. So I extended my hand and took a little of this substance with my fingers and held it in front of my nose, then...

"Sniff sniff... the system sucks. What is this stuff?"

<This substance is the impurities that came out of master's body>

When I heard Al-Nadham's answer, I remembered something similar happening in some of the novels I had read in my previous life.

"Let's start cleaning."

After cleaning, I also took a quick shower, then on my way out, I passed by the mirrors, and what I saw shocked me....
