It was reported in the past that several horses were killed in Kunlun Mountain. When found, the clothes were tattered, there was no trauma, and the cause of death could not be found. So, people cried and felt mysterious. Later, after investigation and development, the magnetic field in this area was abnormal, but why it was abnormal was inconclusive, which deepened people's awe of this area. I think it is called the gate of hell because of the geographical environment of Kunlun Mountain. Because it is a plateau and sometimes a mountainous area, there is basically no human habitation and it is impossible to survive there, so it is called the gate of hell.
Modern science still can't give a convincing explanation for some rumors of Kunlun Mountain, and this mysterious color has become more mysterious with the passage of time and generations. The legend closely related to Kunlun Mountain is that there are many "immortals" and "immortal caves" here, which are often found in martial arts novels. In the distant ancient times, there were rich "gas fields", with lush vegetation and trees reaching the sky. There were spirits and beasts in the mountains, water and air, and the practitioners breathed the gas fields of heaven and earth and condensed the abdomen. When you are successful, you will be immortal. I don't know if it is a rumor passed down from generation to generation or other reasons. In a word, this is a treasure, and we should cherish it.
In fact, the so-called gates of hell or the valley of death can be explained by science and belong to natural phenomena. At the same time, it is precisely because of this that nature is full of such mysteries, and we can always explore and study these mysterious and ancient things.
