MTL - Pursuing Immortality - Chapter 769 guess

Utsuro no Hako to Zero no Maria, or The Empty Box and The Zeroth Maria, tells the sinister story of Kazuki Hoshino, who is almost madly attached to his everyday life, and his antagonist Aya Otonashi, who suddenly transfers into his class—for the 13,118th time. She majestically announces to “break” him, without paying heed to anyone else around them.

The Gura Gura no Mi is known as the strongest fruit in the world of one piece.

In order to avoid marrying an old man from the neighboring county, she must run away. The first time she escaped, the general entered the city, and she rolled and fell in front of him, no, she kneeled in front of him (really not on purpose). The second time she escaped, the general came to visit her house, and the general caught her (he must have done it on purpose). The third time, she was bruised and battered, almost desperate, and he came galloping and took her into his arms. (He was very well-intentioned.) The general said, ” Although I do not want to hold a favor to you, it is true that you owe me a favor.” So? 

 An Ruochen is unwilling to submit to fate and meets General Long three times when she runs away from home. She expects to get help from a powerful man, but she is involved in a secret conspiracy instead. Vicious family, a missing younger sister, a mysterious spy, and power struggles. An Ruochen becomes the key to solving the mysteries and becomes the core of General Long’s heart.
