As an orphan born with an ordinary physique that everyone regarded as “useless,” Xiao Ran was taken in by the Qingyun Sect as a menial disciple. Just as he grew disheartened and prepared to lie flat and pass his days, he unexpectedly activated the [God-Tier Sign-In System]. By signing in anywhere imbued with Daoist essence, he could claim rewards that defied the heavens. Sign in at the Ancestral Hall, and receive the [Chaos Dao Body]! Sign in at the Scripture Pavilion, and receive the [His Freedom, My Freedom Art]! Sign in at the Alchemy Room, and receive an [Emperor-Grade Pill Recipe]! Xiao Ran followed the principle of keeping a low profile, quietly signing in around the sect and silently growing stronger, while outwardly remaining a harmless good-for-nothing menial disciple. During one sign-in, he obtained an ancient sword sealed away for ages, inadvertently awakening the weapon spirit sleeping within: the peerless female emperor Ling Shuangyue, who had lost her memories but still exuded domineering power.
