During Chen Xi's leisure days, the chess pieces scattered by Jia Xu in the northern areas have already bypassed the territory under Yuan Tan's control, and started transmitting intelligence on the Wuhuan Xianbei to Jia Xu.
"Heavy snow?" Jia Xu looked at the casually mentioned piece of information on the report, frowning tightly.
"Fengxiao, do you have any intelligence on the northern climate?" Jia Xu turned his head to ask Guo Jia.
"I'm currently researching the climate of the Xianbei over the past fifteen years." Fa Zheng said, looking up from a pile of bamboo slips. He was quite sensitive to climate, as it was a significant focus of his attention.
"No need to look it up. If it snows in September every year, it means that the Xianbei, Wuhuan, and Huns will certainly come to plunder, and the intelligence we have is from a month ago, meaning..." Guo Jia looked up with a flash of coldness in his eyes.
