Great Qian Sign-In: Starting as a Guard at Demon-Suppressing Pass, I Become Invincible

“His parents died defending the Demon Prison, and he spent three years as the lowest-ranking guard at the Demon Suppression Pass. Then one night, as moonlight soaked the scabbard atop the pass, the System suddenly rang out: ‘Heaven rewards diligence. Sign-in System activated! Sign in daily at the pass tower, Demon Prison, and Legacy Hall to earn Diligence Points and add stats!’ On day one, he signed in at the pass tower, advancing the Demon-Suppressing Blade Art to perfection and cleaving a barbarian scout’s blade in two. On day seven, he signed in at the entrance to the Demon Prison, tripling his resistance to demons and letting him withstand a demon general’s bites without injury. On day thirty, consecutive sign-ins at the Legacy Hall triggered a hidden reward and awakened a fragment of an ancient blade technique! When a hundred thousand barbarians launch a night raid on the pass, and demonic mist seeps through a crack in the seal, see how Lin Xuance uses Diligence Points to forge an invincible path: from lowly guard to Demon-Suppressing Venerable. This time, heaven rewards diligence, and he will ensure the Demon Prison never awakens again!”
