Afterward, Pei Yan organized the evidence on their side and gave a brief explanation.
"Second Young Master, Third Young Master, and the steward are all suspects. The motive for Second Young Master to kill is relatively less urgent. As for Third Young Master, after the Old Prince discovered he was born from the affair between the steward and his mother, both have an urgent motive to kill the Old Prince. However, Third Young Master intended to poison and had already used poison, but didn't succeed, which contradicts the Old Prince being stabbed to death, so we suspect the steward more."
"So from the first round of clues, the most suspicious candidates are the steward and the guard," Wang Sirui speculated.
"Start the second round of searches," Pei Yan said.
During the second round, the evidence cleared the suspicion from Second Young Master, making him the least likely person to have killed the Old Prince.
