The Superpowered Female Boxing Champion Returns to the 1970s and Uses Her Strength to Crush the Wicked

In the 30th century, Mao Yuru was the queen of women's boxing. She had won the Blue Star International Women's Boxing Championship eight times in a row. After accepting her latest award, she was assassinated by mercenaries hired by the enemy while giving her speech. It was a provocation against the Mao family, the Dragon Kingdom's foremost military family.

The only daughter in five generations of the Mao family lost her life in the Beautiful Nation. Mao Yuru transmigrated to the 1970s, an era when women were deeply oppressed by a patriarchal society. She refused a matchmaker's proposal because she did not want to marry in haste, so the sister-in-law who had arranged the match pushed her into a lake. The original owner could swim, but her prospective husband wanted to force the issue before marriage, and she could not swim, so she dragged Mao Yuru into the water and drowned. Mao Yuru avenged the heroine, then used the powerful nation's pocket dimension she had brought with her to help the Dragon Kingdom soar like a dragon.
