Ancient and Modern Salesman

Protagonist: Lu Xiaoman - a modern business tycoon, smooth-tongued, extremely lucky, loyal, greedy and lustful but not scumbag, completely in line with Wei Xiaobao's "Charm" (original character design, not touching Jin Yong's copyright). Time Travel: The ancestral "double-sided ancient jade" triggers two-way time travel from ancient times to the present. It is not a free cheat - there are memory wear, body resonance, causal debt, random squeeze back, and key historical anchor protection; the enemy can also rely on "another time traveler/ancient alchemist/modern institution" to counterattack. Each time you upgrade, you have to complete the "karma balance" task, and you often have to spit out the benefits you have gained.
