I need to talk about Bubu because this moment absolutely wrecked me in the best possible way.
Jiang Luokui spent a hundred years in the cultivation world. She reached Nascent Soul stage. She built a life, however difficult, and then she died—alone, repaying loans she'd just finished paying off. When she wakes up reborn in a university classroom, the emotional baseline is devastation. She's lost everything: her fortune, her status, her century of accumulated power. The author makes us feel this through small details—the math she does converting currencies, the faint sigh when she can't remember why she chose agronomy, the calculation that she's lost "at least one billion."
Then the scalp starts itching.
She rushes back to the dorm, locks the door, parts her hair, and there they are—two small green leaves. Her natal spiritual plant, Bubu, has come with her. The scene where she pulls it out and it transforms into a palm-sized radish creature with bead-like eyes and a slit mouth, saying "A-boo! A-boo!" and "Master—!"—this is the emotional climax of the first three chapters, and it works because it's earned.
A natal spiritual plant is described as the best assistant for tending crops, naturally attuned to plants, growing stronger as the master cultivates. But beyond the mechanical description, this is a companion. Something she had for a hundred years and thought she'd lost forever. The fact that it reverted to juvenile form because of the low spiritual energy in this world adds a bittersweet layer—Bubu is back, but diminished, just like Jiang Luokui herself.
The relationship with Lin Zihan also has quiet emotional weight. They're both D and C rank, both broke, splitting a bag of soil to survive. There's no grand friendship declaration—just Lin Zihan saying "I'll buy the soil myself" and the unspoken understanding between two people who are in this together. It's the kind of friendship that doesn't need words.
