Thus, Jiang Youzhi let it be revealed to Rong Ding the Emperor's intention of keeping the Seventh Prince by his side. Between the words, it was implied that the Emperor originally planned to establish the Eldest Prince as Crown Prince, but suddenly discovered that the Seventh Prince was very intelligent, a promising talent, and intended to groom the Seventh Prince to make him the Crown Prince in the future.
Upon receiving such news, Rong Ding naturally devised a way to deliver the message to Consort Rong.
Consort Rong conspired with the Eldest Prince, and then ordered the Rong Family members to send poison into the palace.
The Rong Family members were clever, choosing not to buy arsenic from the pharmacy, as selling such a deadly substance would be regulated in quantity, and records would be kept. If problems arose, it would be easily traceable.
Oleander, however, is easy to obtain, and its origin cannot be traced.
It is the ideal poison.
