Everyone gathered to see, in the white porcelain bowl was clear water, into which two drops of blood had just sunk, immediately dissolving into the water.
Understanding dawned on everyone, Li Huai was performing a blood test to confirm kinship!
Indeed, just now when everyone was not paying attention, Li Huai had used a silver needle to puncture the skin of Fu Guosheng and Bufan, extracting a drop of blood from each of them and dropping it into the white porcelain bowl.
As for why no one noticed, it could only be said that Li Huai moved too fast. Even Fu Guosheng and Bufan didn't feel the slightest bit of pain.
Although paternity testing by blood analysis was an ancient method with little scientific basis, the fact that this method has been passed down to this day must have its own reason.
