Reports.

After investigating with Blade, he goes to the guards in their headquarters, to ask them to share the information they uncovered from their own work with the people involved in those specific crimes.

What he finds out is:
• The man who tried to poison the river is from Wutian and got paid by a mysterious, rich and foreigner man to do that job. As the person had big gambling debts, he accepted the offering without many questions.
He also poisoned the well at the military camp, sneaking in together with the suppliers when they came to bring the goods.
• The woman who survived the poisoning of the two families said to have bought meat from one of the various meat merchants from the Great Huang. Although she is suspected to have purposely poisoned the meat, the guards were unable to find any connection between her or her family with any person of the other family that fell victim to the poisoning.
• The merchant from Great Huang who sold the meat was promptly arrested and he swore that he took the meat from the usual, government-controlled warehouse from which he has always taken it from. He swears he is totally unaware of any poisoning and doubts that the meat could have gotten spoiled, as it was conserved like every other stock and nothing out of the ordinary happened during the journey. (Although there is open trade between Lianxi and Great Huang, there is no portal between them and the merchants from both sides have to travel by ship. Great Huang main export product is meat, as that's the only thing they have in big abundance, beside ore.)
• The case of disappearance of women extends to all cities. It wasn't a huge number of women going missing, about 3 each city. Furina is among the women who went missing in Guyun.
• Mass poisonings happened in Zae and Youling too, in the same exact circumstances, but not committed by the same person.
• A large amount of food supplies (mostly cereals, rice and legumes) were stolen from the public granaries in Hunai, several suspicious southern men were seen embarking on a Great Huang ship in Wutian, carrying large sacks they acquired through unknown means.

All this following a very extended silence from the Imperial Family, as they haven't sent any messanger or emissary in months, which is out of the ordinary.

After hearing everything, Jing Yuan's worries became stronger, but at the same time, he is finding the situation strange, on a strictly military strategic point of view.

Jing Yuan himself writes a detailed report to summarize his finding, leaving it for Zhongli in the throne room, with a high priority seal on it, so that it will be the first thing he sees when he comes back from Teyvat.
