1970: I have a flash sale system

Qin Yu accidentally traveled to the 1970s and gained access to a magical instant-kill system. Every time he basked in the sun, his physique grew stronger, all for a mere 10 gold coins. One day, he was pleasantly surprised to discover that, for just 10 gold coins, he could instantly kill a luxurious Cullinan sedan. Faced with this sudden wealth, Qin Yu smiled wryly, believing it was the 1970s after all, and his luxury car would remain unused. Even more incredible, Qin Yu even managed to instantly kill a beast hunter. With a sun-strengthening physique, the beast hunter class, and the instant-kill system, his future self held endless possibilities.
