How to implement this was already clear in Qi Sheng's mind.
He had come up with this plan when creating the Challenger System and was just waiting for a shortage of sacrificial power to use it.
That is, a lottery!
Before traveling to Monster World, Qi Sheng had played many games on Earth.
He had referenced many game settings when designing the Challenger System.
He discovered that various types of games generally have a mode of spending real money, like drawing from blind boxes, card packs, roulettes, loot boxes, or playing board games, encouraging players to spend more.
This pay-to-win approach has three advantages.
Firstly, it satisfies the psychological needs of players. Humans inherently have a gambler's mindset, curious and expecting about unknown results. This mechanic uses that trait, allowing players to enjoy the thrill of "winning big from small investments" through payments.
