Queen Anna's matter, Mù Qiānxún has already heard from Juzi.
Juzi is particularly gossip-prone and can't keep her mouth shut. Knowing Mù Qiānxún isn't from Liuli Nation, she told him everything about Liuli Nation.
Especially about Queen Anna.
Queen Anna fell ill upon her return this time.
On Crystal Mountain, a poisonous plant grows, which has a severe hallucinogenic effect.
It also causes addiction, and excessive use can lead to either physical debilitation or death.
This time, Queen Anna was poisoned by someone around her when she went to the Imperial City.
Perhaps Mù Qiānxún was being carefully monitored, confined to this villa, and the only person he interacted with was Juzi, so when she spoke of gossip, she did so without restraint.
Upon hearing the effect of that plant from Juzi, and its effect when processed into a drug, Mù Qiānxún immediately understood Queen Anna's 'lack of foresight' in the Imperial City.
It turned out she had been drugged.
