What is the life stone often mentioned in Japanese anime?

It is said that in ancient India, a Kyubi no Youko fox became a prince and princess Huayangtian, which confused the king, shattered great rivers and mountains, was hunted down by people, and then fled to China, became human, named da ji, destroyed a generation of dynasties, and was hunted down by the gods of the Central Plains. She fled from the water to Japan under the pseudonym of Tamamo no Mae, and continued to confuse the then Japanese emperor Bird Feather. Later, the emperor got a strange disease and lay in bed. So ministers began to doubt her and let Abe Harumi secretly give her divination. As a result, the true face of "Tamamo no Mae" was finally exposed. It turned out to be a Kyubi no Youko fox from China, so she fled the capital and fled to a far away place.

After Emperor Bird Feather knew the truth, he sent Mihura Yichun and general manager Hongzhi to lead an army of 15000 men to hunt down the fox. After two days and two nights of fierce fighting, the fox was defeated and turned into a huge rock "killing stone" The fox turned to stone is very vicious. It often releases toxic gases to hurt people who come over. Later, Xuanweng, a famous monk, split the rock in half with his divine power, and then completely destroyed the evil spirits of the fox. The fox sends out poisonous gas in the stone, and people, animals and birds passing by will die. That's why it's called the life stone.

Now Nasuno's Sesshengshi has become one of the local attractions.

Biosynthetic stone is a poisonous stone on the mountain of Nasu Town, Tochigi Prefecture, Japan. Whether it is an insect or a bird, once it comes into contact with it, it will soon die. This poisonous stone can kill living things. According to scientists, this toxic stone is mostly near the crater. It is toxic because it is impregnated with sulfurous acid and hydrogen sulfide gas emitted by the volcano. Some temples removed it and placed it as a sacred object.
