This legend tells the tale of the protagonist, Kuroki summoned to protect the demon king from the hero.

Kuroki, unbeknownst to him, suddenly came to another world. He was summoned by the demon king, Modes. The territory which the demon king overrules was in the midst of being destroyed because of the hero. He had no choice but to bow before Kuroki.

“Please save us, Savior Dono!”

Kuroki nodded, deciding to save the demon king due to an unexpected turn of event.

Capital is power. The more you invest, the greater the power.

- Description from novelbuddy

Li Wei lived a dull, overworked life—until destiny (or a rogue truck) intervened, catapulting him into a world of mystical cultivators and deadly power struggles. Waking up in the body of Li Wei, the infamous and lazy heir of the Immortal Ice Sect, he finds himself in a precarious position: surrounded by enemies, burdened by a reputation for arrogance, and targeted for assassination. The only thing worse than inheriting this life? Realizing his new body’s cultivation potential is off the charts... if only the previous owner hadn’t been an idle narcissist.With the sect matriarch as his coldly disappointed mother, a stoic yet dangerously competent protector in the ice-cold beauty Leng Yue, and a mysterious “Young Master System” pushing him toward reckless behavior, Li Wei must balance survival with ambition. Every quest forces him to embrace the absurdities of an over-the-top cultivation world—whether humiliating enemies or accumulating riches—while concealing his true identity as a transmigrator.But as he’s exiled from the safety of his sect and thrown into the chaotic world below, Li Wei quickly learns that charisma, cunning, and a knack for manipulation might be even deadlier than swordsmanship. After all, why fight fair when you can command, deceive, and dominate?With ancient relics, feuding clans, and dangerous beauties complicating his journey, Li Wei's rise through the cultivation ranks is anything but conventional. What starts as a quest for survival may just become a path to unstoppable power... assuming his outrageous system quests don’t get him killed first.Will Li Wei overcome his past’s shameful legacy, outsmart his enemies, and become the true master of his destiny—or will his laziness, scheming rivals, and shameless arrogance bring him to ruin?

Saying 5000 year-old-dragon has an impressive ring to it, yet that dragon was an extremely harmless, herbivorous being. However, because of his uselessly giant figure and scary appearance, he was mistaken for the Demon King’s executive and provided by the nearby village with a sacrificial maiden.

Fundamentally cowardly and timid dragon tried to send her away, but the extremely enthusiastic sacrifice didn’t want to give up. Inevitably, he lied: “Okay, I just ate a small portion of your soul, so you can go back already”, but the maiden with outrageous assumptions has misunderstood that she became the dragon’s kin.

Then, out of all things, she began to manifest strange power on the basis of her wrong assumptions – in turn, the helpless dragon, by some mistake started a rebellion against the Demon King.

Rebellion or whatnot, he wasn’t even his subordinate in the first place.
