Zhuge Liang and Liu Bowen both used seven-star lamps. Why do they end differently?

Legend has it that lighting the big dipper lamp can prolong life, and no matter how old you are, you can restore life as long as you have a good breath. If you want to light the seven-star lamp, you have to refuel and know all the tricks. As long as you know the tricks and like them, the ever-burning lamp will always be on, and you can save your life. If the light goes out, it will lead to the separation of life and the disintegration of the body.

Seven-star lamp, also known as "longevity lamp" and "evocation lamp", is an ancient door god, and "evocation lamp" has been circulating since Shang and Zhou Dynasties. "Seven-star lamp" is the lamp that Kongming lit in Wuzhangyuan in the Romance of the Three Kingdoms to extend life. According to Zhuge Liang, "if the main light doesn't go out for seven days, my life can be increased by one year." The two of them lit the seven-star lamp, naturally to prolong life, but the ending was different, one was successful and the other was unsuccessful.

Why did Zhuge Liang fail? It was Sima Yi who attacked the camp at night, which led to the chaos of the army. He was knocked down by the seven-star lamp and sighed, "Life and death have a life, so you can't force it." It can be said that the wise man is broad-minded, but Qin Shihuang could not do this. He spent the rest of his life pursuing immortality, but he didn't die when he was old, leaving a stigma.

When Zhuge Liang captured Meng Huo seven times, there was a king named Wu Tugu, and his rattan armor soldiers and elephant soldiers were difficult to deal with. Zhuge Liang designed them to enter a valley, blocked both ends of the valley with big wooden stones, and set fire to tens of thousands of people. Zhuge Liang hid his face and wept. Although I have made great contributions to the country, I will definitely hurt my virtue! So the seven-star lamp is doomed to failure. Liu Bowen is a master of Feng Shui. He knows how to seek advantages and avoid disadvantages. Most of Zhu Yuanzhang's heroes have no good end, but Liu Bowen died a fair death, which has a lot to do with his usual emphasis on Feng Shui and virtue.
