Shadow Strike: I Rely on Heartbeat Rental to Sweep Backup

At 3:07 in the morning, my master's body opened its eyes on the river beach, with my graduation key stuck in its ear. [Shadow Copy] Mandatory Online - Every time I rent a heartbeat, my shadow lives for me for one year. When the five keys are gathered together, I am free and they retire. Me: A heartbeat of 100 billion, daily payment, and the copy is available for rent! ① Corpses were burned on river beaches, graves were dug up in cemeteries, and corpses were dismembered in air-raid shelters. Signatures were broadcast live throughout the process, and the barrages were flooded with "666"; ②Darknet auction heartbeat, 18 million was recorded in 30 seconds, and the platform will only take the shadow; ③ When the cremation furnace clocks in at 800°C, and before the furnace door closes, the system writes "Next time to enter the furnace" into the pupils. Before the lease expires, the shadow will turn first. Before the copy is leveled, the heartbeat stops first. Turn to the first page and count my heartbeats - one less beat and I will become transparent forever.
