By day, he is a mild-mannered university professor, holding forth with wit and charm at the lectern.
By night, he is the supreme commander of the Boundary Keepers, codenamed "Milestone," suppressing all supernatural forces.
He is Chen Fei, the sole leader of China's eleven Boundary Keepers and the country's strongest fighter.
When a thousand-year-old Zombie King claws its way out of the earth, when foreign superpower organizations brazenly cross the border, when ancient evil gods whisper in the shadows of the city... Chen Fei's life is all about handling crises that could overturn the world, then showing up at school the next day with dark circles under his eyes to take attendance.
Until... a cold, domineering female CEO corners him at school,
And his best friend teases him: "Brother Fei's got guts. He can even give a female ghost maternity leave."
And the baby-faced, voluptuous "Spirit Cat" licks her lollipop and laughs without a care: "Captain, a few more girls have been secretly asking about you!"
The campus belle who admires her teacher, a gentle and capable female colleague, even an island-nation assassin from the enemy camp...
As one exceptional woman after another enters his world, Chen Fei discovers that guarding the ultimate secret of the world seems a little easier than dealing with this romantic battlefield.
