Transmigrated to Douluo: I’m Tang Wutong’s Strongest Big Sister

[Transmigration + System-led + wish fulfillment + male lead gets put through the wringer] All in one go!

An ordinary office worker unexpectedly transmigrates to Douluo Dalu, where she becomes Tang Wutong's older sister, Tang Qianyu, and embarks on a journey of growth.

More than ten years later, she and her younger sister sneak off to Douluo Dalu and meet the male lead, Huo Yuhao. Tang Qianyu begins keeping Huo Yuhao under her thumb in every way.

She cures her sister of her lovestruck tendencies and takes her along for one satisfying victory after another.

She helps her sister set her values straight.

But the System occasionally assigns outrageous tasks, forcing Tang Qianyu to train like crazy. (She gives the male lead a “little” hard time, that's all.)

She uses the System's rewards to build her fortune and found her own sect.

For a time, she and her sister become Shrek's favorites.

{Pure wish fulfillment from beginning to end, no angst}

(I'm new here, so please be kind.)
