According to legend, Lao Tzu once rode a green bull and left Luoyang, exited Hangu Pass, and taught Hu people such as the Western Regions and Tianzhu in the Western Regions (including Tianzhu). Historically, it is known as: turning Hu into Buddha.
Moreover, Laozi's "Tao De Jing" was also written at Hangu Pass, which is also one of the important sources of legends that turned Hu into Buddha. Putting aside the myths and legends of turning Hu into Buddha, Hangu Pass itself is the earliest Xiongguan fort in Huang Xuanguo's history.
Its terrain is extremely dangerous, bordering on the plateau in the west, boundless streams in the east, Qinling Mountains in the south, and Huanghe River in the north.
It is also called Hangu Pass because it is located in the "Two Beijing Ancient Road" and is closed in the valley, as deep as a letter.
Hangu Pass is not only a military fortress, but also an important point of cultural and economic exchanges between the ancient Central Plains and the Northwest and Central Asia. Hangu Pass has been injected with "purple gas from the east", "chicken robbers", "gongsun white horses", and "Xuanzong's reforms "And other historical stories and legends.
There are many more poets here, such as Li Bai, Du Fu, Sima Qian, Tang Taizong, etc., leaving more than one hundred poems, adding to the cultural atmosphere and historical weight here.
"This is Hangu Pass."
Standing in front of the restored Hangu Pass, Li Yun said with emotion: "The legendary place where Laozi turned Hu into a Buddha does not poke needles, and he does not poke needles when he lives in Hangu Pass."
Fanqing Shengqingzhu: "..."
The two women glanced at him together, as if looking at a neuropathy.
Li Yun smiled, "A stalk on the Internet, I just sigh with emotion."
"baffling!"
The cold saint lady certainly didn't complain about him, but Qingzhu didn't have so many worries, and directly gave him a cute roll of eyes, took two brisk steps towards the tall and majestic Hangu Pass, opened her little hand and said cheerfully: "Han Guguan is of course very good. This is the dojo of one of our predecessors in Hidden Sacred Valley. Later, Hidden Sacred Valley moved here for some reason. He left a book on Tao Te Ching, but it is not as you say. Hu is Buddha."
"senior?"
Li Yun was a little surprised, "Is he called Laozi?"
Sometimes Li Yun couldn't tell whether Lao Tzu, one of the three cleansers, was Lao Tzu, and how it was different from Lao Tzu in history.
"Yes! The old man's surname is Li Ming'er, the word is Dan, the word is Boyang, we usually call him Senior Boyang, he used to be the "sage" of the Hidden Sacred Valley."
Qingzhu triumphantly smiled and said, "He is also the Lao Tzu in your outside history books, how about it? He is also the senior of our Hidden Sacred Valley, isn't he surprised?"
For a moment, Li Yun even thought that the fairy tale happened less than three thousand years ago.
Laozi is the saint of the Hidden Sacred Valley?
In the ancient myths in Li Yun's memory, Lao Tzu is one of the saints of the Sanqing.
In the true history of Huang Xuanguo, Lao Tzu is also a saint named by the outside world and the Hidden Sacred Valley.
Li Yun got the memory of the system, myths and legends, records of the Hidden Sacred Valley, and the history of the outside world.
The four are mixed together to describe a huge mystery, and Li Yun even feels that he may not even want to understand it for a lifetime.
In the end he didn't bother to think about it, pushing these specious things to the relationship of parallel universes.
The explanation is also very simple, because it is a parallel universe, so some things are somewhat similar, but very different. In short, it's just that, no matter what.
