One possibility is that the Chu Family Patriarch picked two Dragon Blood Bodhi Fruits back then, auctioned one, and hid the other, keeping it for the promising descendants.
However, besides the Chu Family Patriarch, no one would think that the Chu Family would still hide a Dragon Blood Bodhi Fruit for so many years. The Chu Family Patriarch could have simply handed over the map without surrendering the Dragon Blood Bodhi Fruit.
Another possibility is that the Dragon Blood Bodhi had matured long ago, and the Chu Family picked it again. But if that were the case, it wouldn't just be one; there would be many.
It is precisely because of these two points that Lin Chen has some doubts about Qiao Shishuang's identity. Even if she was genuinely afraid of Zhuo Huai's grandfather silencing her, would not Zhuo Huai's grandfather have been able to find out during their months of travel in the Fulong Domain?
