- Description from Novelupdates

Indra (5) grew up in her family while being shunned and ostracized. When she regained the memories of her previous life, she decided to run away from home and thus trained herself to absurdity.

During her training, she encountered the young adventurer Sword, who looked just like a middle-aged guy. Worrying about the impertinent, eccentric, pointlessly strong young girl, Sword invited her to go on a journey with him.

He had never invested in shares or bought a lottery ticket, and neither did he have any experience in the general business industry. Lu Li found that the only thing he could do was play games.

To be is to have a soul. The soul begets a will. Wills accumulate into mysterious psychic forces, weaving secret domains within the fabric of reality.
