How did the dynamics of comets reveal Qin's fate during Ying Zheng's seven to ten years?

Speaking of Ying Zheng, the king of Qin, there is always controversy in history, saying that he has both merits and demerits, which are reflected in the establishment of the first unified dynasty, the Qin Dynasty, and the formulation of a series of laws and the adoption of many measures to unify the whole country. And his bad temper, enslavement of the people, construction, the pursuit of immortality and other acts, so that the whole society complained. It also made the collapse of the Qin Dynasty inevitable.

But before the arrival of autumn, there were records in history that there was a vision in the sky, and there were rumors among the people that it was a precursor to autumn. In fact, during the reign of Qin Shihuang, there were indeed two times. The first time was the meteorite landing, which was the comet in the title. It landed in Dong Jun, which was then ruled by the Qin Dynasty. In fact, ordinary meteorites may make people think it is a good thing, but the most incredible thing is that there is a line engraved on it, which roughly means that after the death of Qin Shihuang, the world will fall apart.

It spread among the people at once and finally reached the ears of Qin Shihuang. He is suspicious by nature and has long wanted to live forever. Seeing this scene, he wants to live forever. Originally suffering from illness, he died on the sand dune when he went out for the last cruise to find the medicine of immortality.

The second vision is "Mars stays in Antares", which was called a disaster by the ancients. In fact, in modern times, Mars moved near Scorpio, but in the eyes of ancient people, it indicated that the emperor's country was in danger, or the emperor might be doomed. The appearance of this phenomenon also made Qin Shihuang panic and more eager to get the elixir of life, but it also aggravated the demise of the Qin Dynasty.
