My Journey to the Alien Lord Is Too Hardcore

When someone else travels across time, he becomes a lord: he uses power to check and balance, uses both kindness and power, and is on guard against being stabbed in the back by his subordinates every day. Li En traveled through time and became a lord: when he woke up, his subjects brought food to them, and when soldiers went out, they cleared away all the monsters. Even newly captured enemy prisoners volunteered to go mining to atone for their sins. In the magical world of the wasteland, everything can be exchanged in the World Tree Exchange. There are all types of soldiers, blueprints, and resources, but the human heart is the most difficult to control. Fortunately, it comes with the favor and blessing of the World Tree, and the loyalty of all members under his command increases at the beginning. There is just a small worry: his subordinates are too capable, but he, the lord, seems to have nothing serious to do except visiting the exchange and sunbathing every day.
