Abilities & Skills

Possession

Sin Beasts can abandon their own bodies to possess living beings, awakening the evil hidden within their hosts 1.

• Infiltration: Possessed people are found among physicians, household guards, powerful families, and Shenglin City’s soldiers 1 3 6 10.
• Detection difficulty: Natives find possession difficult to recognize. The player system automatically marks Sin Beasts, including those inside hosts; Lin An sees a bright-red skull above the possessed Physician Liu 1.

History

Earlier Attacks and Lin An’s Previous Life

A Sin Beast killed the native Lin An’s mother when he was eight, leaving him deeply traumatized. Lin Xiao also lost his father during a Sin Beast siege ten years before the current attack 1 41.

In Lin An’s previous life, Shenglin City fell to Sin Beasts on December 15, 3215. Lin Xiao detonated himself in an attempt to take the attackers down with him. One year after Sin Abyss appeared on Blue Star, its world connected to reality, allowing countless Sin Beasts to invade and cause an apocalypse in which Lin An died 1.

Shenglin City Infiltration

After awakening in the past, Lin An recognizes Physician Liu as possessed and kills the Resentful Tiger inside him. Using the system’s detection markers, he then helps Lin Xiao uncover seventeen possessed personal guards, numerous infiltrators in the Zhao Family, and 372 possessed soldiers in the eastern garrison 1 2 4 6 10.

Spirit Realm Hunts

Lin An uses Sin-Luring Crystals to gather and slaughter large groups throughout the Bronze Tier Spirit Realm. The beasts become stronger toward its center, where tens of thousands surround a treasure-bearing valley 29 30 31 32.

Inside the valley, Lin Xiao’s stored phantom attack destroys thousands of beasts. A hidden Silver Ninth Grade Purple-Patterned Poison Toad survives beneath the lake, but Lin An kills it with a combined saber strike and reaches the Heaven and Earth Spirit Crystal 35 37.

Siege of 3214

Sin Beasts converge on Shenglin City from all four directions, eventually numbering around 180,000. Their assault begins at noon on October 4, 3214, with approximately 100,000 attacking the eastern gate 40 41 43.

The Thunder Griffin and Flame Hell Dragon Lizard direct the siege, sending Silver Realm beasts against Lin An before attempting an ambush. Both commanders are killed, leaving the surviving horde without coordinated leadership. The siege ends with Shenglin City intact, and the defenders recover materials from roughly a hundred thousand corpses 45 46 47.
