MTL - I Became A Virtuous Wife and Loving Mother in another Cultivation World - Chapter 220

The formless ancient world was infested with despicable demons. They hunted and feasted on mankind, keeping the human civilization constantly in a weak and suppressed state.

During the first known year, a magical mountain descended into the world from the realm of the Gods. Carved on this enormous mountain was a message: ‘Heaven Prevails’…

After the Grand Descent, a name that was given to the descending of the mountain, the Three Great Sages made their ways to Mystic Mountain where they learned to harvest what we now call magic, establishing the Mystic Cults and eighty-one sacred shrines to help aid mankind with the cult’s mystic powers against the eternal fight to the death with demons.

You’re saying you’re the hero?”“Uh…I think…?”And so, that was the start of hell.

As a successful villainous BOSS, in addition to having ideas and aspirations, one must also keep in mind three points:First, grow sneakily, don't act rashly (once a villain acts rashly, they basically won't survive past three chapters).Second, you're not a good person, so be ruthless (becoming more evil will make you three times stronger, while redemption weakens you by seven times).Third, remember the two points above. The moment you forget them, your end is probably on its way.

A soul was employed by a higher being to help him manage his world. How will our protagonist live her life to the fullest while also fulfilling her new duties?I don't own Naruto. I adjusted the story to my liking. English is not my main language so don't bother about grammar mistakes too much.
