- Description from Novelupdates

Humanity was on the brink of destruction. Muyoung, an assassin from the Forest of Death, fell to his knees. There were corpses all around him. For years, he had worked for the Forest of Death and had finally been able to eradicate them. Now, he, himself, was about to die. He closed his eyes as he felt his heart stop beating.

Bob was a good guy. He had done everything you were supposed to do. He exercised, he kept to a healthy diet, he'd studied hard, gotten excellent grades, and was working towards his masters. Somehow, things just weren't working out for him like he'd been told they would. He was stuck in a thankless position, constantly passed over, and it seemed that the only being on earth that cared about him was his cat.

Then things got worse.

Never back a man into a corner unless you want to find out just how hard he can fight.

[Female lead with no romantic interest + ancient female awakening + passionate righteousness + refusing to be a submissive woman] After failing to conquer the emperor, the system punished me by forcing me to livestream modern life to ancient people.

The man I personally supported to ascend the throne saw me wearing a strapless minidress and dancing seductively at a banquet amidst revelry and wine, and he flew into a rage, accusing me of violating womanly virtues.

I smiled calmly and pointed the camera towards a modern street, launching a shocking livestream for the ancient people!

“Good heavens? It’s nighttime now, but what are those pearls shining so brightly?”

Female lead: Those are light bulbs.

“There are indeed objects in this world that can transmit sound over thousands of miles away. What a marvelous treasure!”

Female lead: This is a cell phone.

“How could the women on the streets dress so scantily and shamelessly flirt with men? Don’t they know propriety? Why hasn’t the county office come to stop these debased women and thrown them into pigsties?”

Female lead: Because this is the glorious era of China!
