I, Supreme of All Realms, Sign-In to Millions of Years

After transmigrating, Su Yu pretends to be foolish to avoid trouble and is sent to guard the tomb of the Tianxuan Sword Sect. He accidentally awakens a sign-in system, gaining opportunities like the Celestial Meridian and the Godly Elephant Prison-Subduing Technique. Disguising himself as an idiot, he secretly cultivates, breaks his physical meridians' shackles, and his power surges rapidly. Facing persecution by the Xue family and pursuit by the Holy Pavilion, he teams up with Liu Baiyuan, Wu Qingfeng, and others to slay powerful enemies, unravel conspiracies, and rescue the imprisoned Liu Baiyuan. Later, to find blood vein grass to treat Wu Qingfeng, Su Yu embarks on a journey to the Hundred Breaks Mountain, continuing to uncover the secrets of his past and the Holy Pavilion.
