My Grandson’s Grades Were Stolen, Revealing His Grandpa’s Identity as a General

9759 Hours of Book Shortage

I want to read a book similar to "I can do whatever I want in the last days (Finale)". At 9759 hours, I am short of books. There are very few novels that I can finish. Please recommend some good books of various types.

Any Douluo Dalu Stories Where the Protagonist Wins Qian Renxue's Heart and Joins Spirit Hall?

Douluo Dalu: The Protagonist Opposes Tang San and Wins Over Beautiful Women

Torture Tang San, Beat Up the Master, Join the Consecration Hall, and Become Its Beloved Darling

The protagonist should be powerful and seize Tang San's opportunities along the way. If there's a female lead, she mustn't be a pushover: she should kill whoever needs killing. The divine position should preferably be the Asura God. If there's a male lead, no harem, and preferably a twin martial soul. No more than three martial souls, or it won't be any fun.
