Ten days passed since Chenglei went to the East and Xing was reading the letter he sent to her. He had mentioned about the drug that is colourless and odourless and is not identifiable once it is mixed in a liquid.
The drug had opioid qualities and the users had some kind of out - of - body experience and it was extremely addictive that even one use makes the user a slave for the drug.
Chenglei mentioned that a farmer salted his entire two acres of fertile field because he was "told to do so if he wanted more of that drug" by the dealers. There were increased rate of murders and robberies since those addicts were doing it to be able to afford the drug.
All in all that drug seemed to be extremely dangerous and it seemed it was used as a form of warfare in Xing's opinion.
Is the Fire Kingdom and Prince of Kang really responsible for this? Are they Proclaiming war on us?
