Among the Myriad Worlds: Kong Yiji Begins by Marrying a Young Widow

Synopsis:

Also known as The Single Chinese Teacher with Women in Every World and The Homeroom Teacher Transmigrates Across the Heavens, and His Ways of Completing Missions Are a Little Wicked!

Yang Ziling, a small-town test-taking machine, spent over a decade studying only to trade it for decades of drudgery as a teacher. His work went poorly, and he was terminally ill, leaving him feeling helpless.

Then he obtained a System that let him transmigrate across the heavens. Completing missions earned him random rewards that helped him solve his real-world problems, and he grew more and more badass.

In Kong Yiji, he becomes Kong Yiji and must complete three missions: marry the virtuous, beautiful widow the original character has long yearned for, earn the title of licentiate, and bring Ding the Imperial Scholar to heel.
