(A strange bowl connects the modern world and feudal China. You buy a golden bowl from an antique shop. However, you are tricked into thinking the gold is fake, and you angrily throw a bone into the bowl.)
(Meanwhile, an ancient general and his soldiers were getting weaker, they were in dire need of food and water. Suddenly the bone you threw into the bowl flew out from another golden bowl from the feudal era, it fell on the ancient general and the soldiers raised their guard for fear of an ambush. However, the general discovered the miracle from the bowl, he and the deputy general knelt before the bowl and began to thank, they thought this bowl was sent by the gods but they did not know it was connected to your world.)
感谢上帝,我们为士兵们提供了充足的水和食物,希望上帝保佑。(translate: Thank God we have plenty of water and food for the soldiers, God bless us.) The general wrote on a piece of white silk paper, they put the letter in a bowl and accidentally sent it to you.
[Note: Both sides cannot talk to each other but can write letters to communicate with each other. Good luck]
