In the Year of Famine, the System Insists That This Is the World of Cultivating Immortals

Li Sheng traveled back in time to a famine era, with only a sister who was about to starve to death and a half-pot of bark soup. Suddenly something popped up in my mind, calling itself "All Things Identification Assistant Program". It said that my sister had "withered spiritual veins" and had to drink third-level rejuvenation liquid. It said that the poisonous Kusizi seeds all over the ground are "first-order spiritual plants" and can be eaten according to the "Five Calcining and Removing Methods". Li Sheng thought this thing was crazy. But he had no other choice. Follow the directions on how to deal with the tangerine. My sister came back to life. Follow its prompts to find the underground cave. The training ground for ancient warriors has reappeared. When bandits entered the village to steal food, the system identified the bandit leader as a "first-level physical practitioner with an old injury to his right knee" - he led his men to the enemy's lair overnight, leaving no one behind. When the sect's power came to the fore, the system determined that the opponent's elder was in the "Tongmai Realm, and the old injury on the left rib can be broken" - he said, then fight. Later, when people in Qingyuan Town mentioned the man named Li in Qingshan Village, they all told him not to mess with him. He had a hatchet stuck to his waist, and behind him was a village of people crawling out of the dead.
