Zheng Yao was indeed implanted with the planting life, but as for who truly wanted the Great General's life, Qin Liuxi did not get involved. She had already done what she could, and matters like these involving conspiracies were likely court intrigues.

After all, even though the Tiger Talisman had been returned, many in the military would only acknowledge the actions of the former Tiger Talisman holder. This was a bond formed from shared life-and-death experiences and respect. So even if some Generals stepped down, they wouldn't be completely without connections. If it were a troop trained by themselves, they would be even more faithful to his name.
Luan Bailin was not only trying to prevent his secret from being discovered but was also plotting for those connections of the Zheng family.
