I Lost the Leash of the Yandere Male Lead - Chapter 21.2: I sincerely apologized to Igelto, knowing that no excuse would work.

Mo Chu was reborn. She opened her eyes to find herself in a world where a thousand years had passed. The docile animals and plants became very aggressive, and elemental abilities that existed only in stories and legends now appeared before her eyes! Fortunately, upon waking up, Mo Chu gained a nice-guy brother who had a sister complex. Unfortunately, she had a one-in-a-million sensitive constitution, so she couldn’t consume 99% of the available food. However, there would always be a solution. If she couldn’t eat the food of this era, couldn’t she come up with new food? And so, she made fries, grilled fish, beggar’s chicken, and various other delicacies that were not available in this future world. As a glutton, Mo Chu was satisfied with this outcome. However…

He Lang died by his own hands for the sake of his imperial younger brother’s ambition, whom he loved. He was offered to be reborn in exchange for giving up his past romantic feelings. Reborn without the burden of his romantic feelings, he brings with him a manual to new worlds. He wholeheartedly followed the instructions of the manual to complete the tasks, not knowing that the originally slag gong was blackening…
He pleaded to his affectionate Emperor brother to release him, he pleaded to the paranoid prisoner next door, but until the end he remained baffled.
In the end, he discovered that the full name of the manual was – “Slag Shou Cultivating Manual”
