Five Dynasties: the Pillar of the Country? I Will Be Defeated as Soon as the Country Is Overthrown

Modern soldiers travel through time and become Li An, the leader of the defeated troops of the Later Tang Dynasty. As soon as he opens his eyes, he is trapped in a dead place. There are enemy soldiers searching and killing him in front of him, but there are no reinforcements behind him. He does not seek to be king or hegemon, nor does he seek to conquer the country. He just wants to find a safe place with his remaining soldiers to survive. Fortunately, I have a military map in my mind that can identify the terrain and predict dangers, so that I can find a glimmer of hope in troubled times. I just want to live a stable life, but troubled times never allow anyone to retreat. Enemy troops were chasing after them, feudal lords were fighting against each other, and soldiers were looting... Let's take a look at how a small defeated soldier managed to protect the people around him in the chaos of the Five Dynasties and find his own stable life step by step.
