From MC'ss perspective:
Store Room,
After waking up, I didn't immediately appear outside. I decided to start my practice. I don't know how long I'm going to stay in the Capital.
So it's better to use the environment here to improve my strength further.
I appeared in the middle of the hallway. Then I sat cross-legged on the ground. After closing my eyes, I began to run the gravity ark method.
Right after, I perceived the gray color mana particles in the surroundings. Then slowly the mana particles entered my body.
Then I circulated the refined mana according to the mental method. After circulation, the refined man settles down inside my mana core space.
The rock-size mana core immediately starts to absorb this mana. When it was over the mana core slightly increased in size.
Seeing that I continued to repeat the process.
Time passed in a blink of an eye,
