A Small Border Town: I Use My Account Books to Extend My Life for a Hundred Years

Chen Yansheng's soul traveled to the border area and adopted a son-in-law. His family was surrounded by poverty, his Yue family looked down upon him, and the village children insulted him like he was throwing away his shoes. On the surface, the Chen family is a farming and studying family, but in fact it is a reclusive and immortal family. Their bloodline is sealed for hundreds of years, and their life span is not visible to the outside world. He awakened the "Fire Observation Technique", and when he was young, he burned a lamp to record events and peered into the embers of other people's life flames. After a hundred years, he could obtain a drop of embers' oil and predict the secrets of heaven. From being a despised son-in-law to taking charge of the fate of the family, he used account books to set up defenses and quietly laid out his plans in the world of fireworks. Avoiding disasters and famines, changing waterways, and storing medicines to prevent epidemics can silently reverse the rise and fall of a village. When the imperial court spied on him, the sects coveted him, and the earth line was about to awaken, he lit the last drop of ember oil and led his people to face the enemy with their lamps. The lights never go out, immortality is restarted, and the fourth immortal clan has stood between heaven and earth since then.
