Nobunaga’s Imouto is My Wife - Chapter 17.1

Qin Ran just wanted to cultivate immortality, refine pills, and live a carefree life as an immortal world slacker. But a genius female disciple just had to get clingy, insisting that he take her as a disciple. Not only that, she was always making advances on him, thoroughly disrupting his peaceful slacker life…

Li Qi, who originally believed that even after being reborn in another world, he would still spend his life in mediocrity, unexpectedly gained the ability to track his progress on the path of cultivation. This rekindled his ambition and gave him the courage to embark on the journey of seeking The Way. A man with a determined heart should strive to overcome mountains and rivers, creating ripples that stretch for thousands of miles as he pursues enlightenment and mastery over his own destiny.

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”
