I've Sold Fake Manuals for Decades. When the Debunkers Came Knocking, I Finally Got It

[Urban High Martial Arts] [System] [Bluffing]

Zhao Qingshan has spent eighty years in a high-martial world since he transmigrated, making a living by selling fake manuals he saw back on Earth in his previous life. Then Liu Cuihua, a victim of his scams, comes looking for him. The moment she presses a broadsword to his neck, he binds to a System.

Sell a hundred copies of a self-created manual, and he can master it. Sell a thousand, and he can perfect it. Sell ten thousand, and he can reach the Dao Realm.

Anyone who cultivates his manuals also transfers their cultivation to him, stacking it onto his own.

A fake manual still counts as self-created, right?

He even offers after-sales service with every manual, guaranteeing that buyers learn it.

He used to bluff people with fakes. Now they really work.

I'm not good at writing blurbs, so please head straight to the story.
