You're Just a Hunter. Is It Really Reasonable to Vie for the Central Plains?

After accidentally transmigrating into the body of a young military household member on the ancient frontier, Fang Ning discovers that the Great Zhou is beset by natural disasters and man-made calamities. The barbarians run rampant, the people are destitute, and his heartless superior would devour him alive. To support his wife, he draws on knowledge from his previous life to hunt tigers and kill wolves deep in the mountains, gradually amassing wealth and manpower. From then on, he makes his vicious superior grovel, wipes out the savage barbarians, and earns the adoration of the Great Zhou court. Fang Ning rises to become the peerless God of War who saves the realm! Wait, I only went hunting. Why are you asking me to found an empire?
