In a certain world, there was someone who excelled in magic combat, people called him 『Sage』. Seeking the strongest combat art, he devoted himself to research every magic and combat arts in existence. And the conclusion he arrived at was very cruel, 『My body is not fit for magic combat』. Yet he didn’t give up. He sealed his own soul with a magic art, and was reborn in a far-off future. And the magic theory in the completely changed world he saw there was of unbelievably low level.

In her previous life, An Xiulan had been oppressed and tortured by the members of Duke An's household. Her legitimate status wasn't enough to save her from the schemes of jealous siblings. For sixteen years, she tolerated the oppression inflicted on her but in the seventeenth year, she was pushed to death into the frozen lake.

Now she has reincarnated into the body of a youthful girl in the modern world who died in a car accident. She was given everything she was devoid of in her last life– family, love and education.

Graced with a new life, An Xiulan is determined to strive towards a better life. She will be the best daughter. She will study hard. And she will stay away from puppy love.

Nothing must come between her path to become a top scholar!

But there seems to be a hitch in the plan.

Why was the backbencher Han Zixin following her to the library, laboratory, playground and even the principal's office?

Wasn't Big Boss Han allergic to studies?

Why was he following the campus Belle?

…

Teacher: An Xiulan is a top student. We must preserve her at all costs.

Class Ten gulped as they recalled how a certain bro-con had supplied cheating slips to his model student sister in monthly tests subsequently resulting in her topping the exams!

Lu Xuan: No one is allowed to bully my sister!! Only I can bully her!

Everyone in class Ten: ????

A few days later, class Ten witnessed the delicate looking youthful girl chasing her self proclaimed brother with a hockey stick!

The delicate looking campus Belle wasn't delicate at all!

...

A delicate girl can't possibly make two big gangsters of Jingyuan Highschool dance on her tunes?

Su Yang traveled through time, into the body of ordinary people.

Fortunately, swinging a sword can improve sword intent.

After continuous improvement, Su Yang found that there was something wrong with this sword intent.

[Wild Supreme Sword Body]

[Handcrafted Sword Spirit Root]

[Solve communication difficulties, rub the sword net with your hands, and start ancient surfing]

The strength increased too fast and was targeted by the lv30 boss?

Su Yang looked at the lv99+ above his head, the old monster should lie down in the coffin.

Enemies from the sky, immortals destroy the world?

Then I, an ordinary person like me, will make a move.

One sword transforms all kinds of methods, and I will rub whatever is lacking.

[ps: Invincible flow, cool text, cool all the way, no aggrieved, no suppression, no brainless pretending to slap your face]
