After Transmigrating into the 1970s, the Three-Year-Old Cannon Fodder Became a Group Pet

It's a story featuring dual purity in romance, group favoritism, childhood sweethearts, transmigration, a portable space, and a system.

Liu Xinnuan transmigrated from a tough girl in the apocalypse into Nuan Bao, a three-year-old cannon fodder destined for an early demise in a period novel. While other children were starving, Nuan Bao kept her belly round by releasing mutated animals from her space.

What if her spiritual energy was depleted? Nuan Bao said, "It's fine, I have my power bank big brother; ten minutes of charging, and he's on standby for half an hour!" A certain big shot replied, "Whatever makes you happy!"

Oh, she found a jewelry box hidden by her grandmother, and with a wave of her small hand, it went into her space! Oh, she found the Ginseng King stolen by the female lead, and with a wave of her small hand, she planted it in her space. Oh, she found the female lead helping human traffickers sell children, and with a raised small hand, she reported her without hesitation.

Nuan Bao thought, "Indeed, if you don't court death, you won't die. Constantly testing the boundaries of death, no matter how great the female lead's halo, it's useless!"

System: "Host, you finally rescued me from that woman's hands! Wuwuwu!"

Liu Xinnuan: "If I say I never intended to snatch the female lead's system, would she believe me?"

A certain person, who evolved from a power bank to a research big shot, snapped, "Scram, dog system! If you interrupt my two-person world with my wife again, I'll directly shut you down permanently!"

System: "Wuwu, indeed, love fades. After Master got the host, he no longer loves the system QAQ."
