Regarding the solution to the locust plague, Zhao Yao has already written to the Emperor, and he can only wait for the results now. If possible, he would like to personally go to the north and deal with the locust plague himself. Unfortunately, as a Vassal King, without an imperial decree, he cannot leave his own territory at will.
Zhao Yao trusts the Emperor's methods and speed. For the next few days, he temporarily did not focus on the northern locust plague, instead devoting himself wholeheartedly to the early rice harvest.
If the northern locust plague is severe, then all the northern provinces will be affected, and northern grain will become scarce, possibly leading to disaster victims. To prevent a massive influx of disaster victims in the north, Zhao Yao decided to send some grain there.
