I’m Only Ten, So What’s With This Late Bloomer System?

Guys, who can relate?! I transmigrated into the body of a ten-year-old borderland boy in the Great Li Dynasty, and the Late Bloomer System showed up. [After fifty years, having endured every hardship and achieved nothing, you return to a border town. On the way, you pass the grave of your childhood sweetheart, who died tragically while hunting in the mountains on your tenth birthday.] [Thinking of the dead, you remember the past. Looking back on your life before the age of ten, you realize you had a tender, unspoken love for your childhood sweetheart. Mission: Pour your heart out to the grave of the childhood sweetheart beside you within one minute. Reward: ...] At the village entrance, Chen Mu watched the girl preparing to head into the mountains with her father and the village hunters. He froze for a moment, then shouted, “Lin Xiu, I like you! I want you to be my wife.” Half a year later, news of a great victory at the border reached the capital: a young man had slain tens of thousands of demons with a single sword stroke. [Having just arrived in the capital, you vividly recall the humiliations you suffered as a boy. Mission: Write a letter of divorce to Bai Qingcheng, now the matriarch of the Great Li Liu family, then walk away with a flourish. Mission reward: One Breakthrough Pill.] When the capital's young lady secretly went to see her valiant, renowned fiancé, he flung a letter of divorce right in her face.
