My Laid-Back Master Mistook the Demon Lord for His Substitute, and He Went Mad

#Laid-back Master vs. Unhinged Demon Lord #The substitute is fake, but the feelings are real #We were never meant to meet, but my bad eyesight brought us together# Modern-day office worker Yun Zhirou accidentally transmigrates into a book and becomes a “lazy” master of an immortal sect. In the original story, she sacrifices herself to save the world, but Yun Zhirou only wants to retire in peace. One day, she comes across a gravely injured boy, Xie Jin, and takes him in. He looks just like the “one she can never forget” who has passed away, so Yun Zhirou accepts him as her disciple, simply because he’s nice to look at. She treats him as a “useful tool” who won’t get in the way of her slacking off. She doesn’t know that Xie Jin has long since realized he is only a “substitute.” He willingly pretends to be docile and stays by her side, all to uncover the truth and take revenge on the hypocritical immortal sect. He had planned to watch coldly from the sidelines, but Yun Zhirou’s seemingly insincere defense of him, feeding him, and “lazy-style” tenderness gradually make him fall for her. When Xie Jin’s identity as the Demon Lord is exposed and the immortal sect moves to eliminate him, the seemingly indolent master steps forward and drives off the enemy with a single sword strike, stunning the sect: this lazy fish is actually a peerless expert! Later, Xie Jin imprisons Yun Zhirou in the Demon Palace and crushes the keepsake she treasures from the man she once loved. His eyes blaze with possessiveness. “Master, I’m Xie Jin, not him! I meant it when I played this part... so now you have to play it for the rest of your life!” At that moment, the “Creator God Retirement System” activated in Yun Zhirou’s sea of consciousness issues a warning: the world-ending threat, Xie Jin, is out of control. She must reform him, or her retirement plan will go up in smoke! Yun Zhirou is on the verge of tears. “...Is it too late to run away?”
