Cheat 1 of Dad's three life cheats — history, statistics-inclusive numeracy, and object-orientation. This quest treats history as a sample dataset, not a fact dump. The 春秋戰國 era (770 BCE – 202 BCE) is the base — roughly 570 years dense enough that almost every root class of human behavior shows up at least once. You meet 환공·관중, 항우·범증, 유방·한신, 장량·범려, 소진·장의, plus the empire pattern, the hubris-control mechanism, the cycle of radical-becoming-conservative, the dark-forest doctrine of 손자 + 한비자, and a modern restatement (류츠신's Three-Body, Dad's Fourth K insight). Cross-cultural confirmations (Alexander, Genghis Khan, Caesar, Napoleon) appear sparingly — they prove the molds are universal, not that you need to memorize more samples. The closing track hands you a homework: pick living people from your own time and write a short novel about which mold each is an instance of. Six months later, re-read your novel against reality. That feedback loop is the cheat.
