The forensic doctor confirmed that this batch of facial cleanser and face masks indeed contained pine poison, but what was strange is: he tested ten boxes in total, seven of which were poisoned, and three were not.
The forensic doctor then scraped three samples from those seven boxes to test for pine poison.
Only one of the three samples contained the pine poison, while the other two did not.
That is to say, the poison was unevenly distributed and could not have originated from the raw materials since Nan Feng cooked them in one pot. If the raw materials were poisonous, then everything in the pot should be poisonous; it shouldn't be so scattered.
In the courtroom, the owners of the Medical Hall who supplied Nan Feng, the couple Li Moxiu, and the workers were all present.
Lord Song interrogated each owner of the Medical Hall one by one, as Nan Feng's raw materials were purchased from them.
