In an age of declining spiritual energy, when evil beings thrive on humanity's darkest impulses, Lin Xi, the last heir of the Xingyuan Lin family, is cursed to “die before turning thirty.” He scrapes by in a shabby antique shop. During a sinister midnight scheme, he is forced to awaken his family's heirloom bronze luopan and blood-stained ancient jade, inadvertently rousing Su Ye, the amnesiac tomb-guardian beast who has protected the Lin family for a thousand years. Bound by a blood pact, the man and beast form an alliance of life and death. Using their family's nearly lost art of stargazing, they fight Lovecraftian horrors lurking in the shadows of modern cities: electronic wraiths born from livestream tips, tides of vengeful spirits spread through subway signals, and memory-eaters lurking in 5G base stations...
> When black-market traders from the ghost bazaar use a Lin family heirloom as bait to push him into the Hundred Ghosts Tower, and the tech mogul Shen Xinghe gives him a strange pocket watch that can scan star charts, Lin Xi gradually realizes that he has long been a key piece in a thousand-year game. Only by guarding his heart with starlight that burns away all filth can he kindle the last lonely lamp of the night watch in this hellscape of human nature, and keep it burning for a broken world.
