Zhuge Qixing borrowed his life

This is a lamp that Kongming lit in Wuzhangyuan in the Romance of the Three Kingdoms in order to prolong his life. According to Zhuge Liang, "If I don't extinguish the main light within seven days, my life can be extended by one year" (the first year is 12, which is a commonly used number in China), but in the end, the light went out because Wei Yan entered the customs quickly. This matter can be found in Romance of the Three Kingdoms 104.

According to the arrangement of the Big Dipper, the main light is in the middle (seven lights in all). Every night from the Shihai era to the ugly time, people who seek longevity will light it and then walk up the highest steps to seek longevity. Sixty-four flags are arranged beside the lamp according to gossip. There must be different immortals on each flag. Add two-thirds of the oil after walking every day, and then order it after going out at night. If the main light goes out halfway, it means fate, and you are desperate.
