The world was consumed by a vile corruption brought from beyond – the sun dimmed, and life as we know it was almost extinguished.And yet it was not the end but merely the beginning.Long after the disaster, a lone survivor awakens with a newfound power to wield the divine flames and many questions about the past. He embarks on a long journey to burn the rot away, discover what's left of the old world and maybe, just maybe, ascend to divinity.

[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!

After waking up in the body of the Young Master of the Luo family, he finds he has the knowledge of hundreds of games and Light Novels. However, he finds his Dantian is crippled, so he can’t practice cultivation! Luckily, he has the Upgrade system.

Killing Monsters, doing Quests, and even killing people- it’s just too easy. I don’t have any Martial Arts? I have hundreds of light novels, just let me level up so I can get this Main Character’s Martial Art! The only problem is: Should I follow the “This OP character cultivation” or should I follow “Another OP character cultivation”?! The tragedy!
