The next morning, when Xu Guangling came down from the mountain, he faced Lao Tan who was left behind.

"Brother Xu, are you really a stranger?" Old Tan's respect has always been there, but now there is a little more inexplicable excitement.

Anyway, what are you excited about, it's not that you have special abilities!

Feeling a little bit of his mental activity, Xu Guangling complained like this, and then said with a smile: "Changbai Mountain is an immortal mountain, have you heard of it?"

Like reading Buddhist classics, Xu Guangling had also read Taoist collections before, although he had read them in a vague way, and he had already omitted a lot of content.

But I still touched something.

For example, since ancient times, there has been a saying for "immortals" in China.

Immortals, from the point of view of word creation, are a person and a mountain, so the usual interpretation is that they are people who escape from the world and cultivate in the mountains.

There is a couplet that says, "There are many famous mountain monks in the world, and there should be one or two strange peaks to live in my Taoist friends; ”

Well, this is supposed to be a "competition" between Buddhism and Taoism, but it reflects a problem, that is, people of Buddhism and Taoism like to live in the mountains.

Some people will say that this is not very normal, the mountains are clean, the scenery is still very good, and the air is still very fresh.

In fact, none of these reasons are very sufficient.

Speaking from the last one, the air is fresh.

As a person of this era, I am very sensitive to this aspect, because there are few people living in cities who do not know about haze, and even in those cities that do not have much haze, the air quality is not good, let alone fresh.

Therefore, when it comes to "fresh air", it is generally desirable.

Even in rural areas, far from the city, it may not be possible to avoid smog, and the air is more or less polluted anyway.

But what about antiquity?

Industrialization has not yet begun.

Anywhere, as long as there are any trees, the air will be quite clean and fresh.

Therefore, the air in the mountains is very fresh, and this advantage is dispensable, and it has been greatly reduced, and its influence is really not so great.

As for the view?

What does that mean? The scenery in the distance is the view.

No matter how good the scenery is, if you live permanently, that's it.

And purity, it is even more untenable.

Didn't Tao Yuanming have a sentence, "How can you ask you?" ”

The heart is far away from itself!

In short, if you want to be lively, then move to the downtown area, and it must be directly facing the street, otherwise, even if it is behind the street, a small courtyard, can easily keep the hustle and bustle out.

All in all, in that environment in ancient times, living in the mountains really didn't have that much advantage.

On the contrary, the inconveniences of life are obvious.

First of all, the air will be relatively cold, in the morning and evening of spring, summer and autumn, it will be so cold that people's bones are stiff, and in winter, a heavy snow will come down, and the door will be closed directly, not only the door will be closed, but also the mountain will be closed, as little as ten days and a half months, and more than two or three months, so that you can't go down the mountain.

Secondly, the water source in the mountains is not so convenient.

There is certainly no running water, and even if there is a spring on the mountain, it is impossible for all residents to live by the spring, so the project of carrying water is inevitable.

And it's every day.

You can carry water easily and still work out?

Yes, that's true, it seems that you can get fit, but it's really not easy. If you are in good health, you can cope with this errand by exercising, and if your body is not so good, carrying water is always a chore.

Again, it is inconvenient to eat, you can grow some vegetables on the mountain, but more places are not suitable for even vegetables, as for rice, flour, grain and oil, etc., all have to be bought regularly down the mountain.

......

All in all, living in the mountains is just too much of an inconvenience.

The benefits are not so great, but the disadvantages are too many, and the sum of the two makes it possible to "live in the mountains", at least, the cost performance is not so high, right?

So why are they still running into the mountains?

Not only that, but they also came up with the saying of "Cave Heaven Blessed Land", all "blessed land" are all kinds of mountains in the world, and all "cave heaven" are caves opened up on the mountain, or dwelling.

All in all, whether it is the cave or the blessed land, it is inseparable from the mountain.

In the past, when Xu Guangling read this, he had a feeling that the people in these caves were really humorous and optimistic about life, calling the simple caves Dongtian, and the famous and unknown mountains and small hills called blessed land.

In this way, what was originally very lo instantly became tall and tall?

But since discovering the "Qi of the Earth, Mountains and Rivers", Xu Guangling thought of "immortals" and "Cave Heaven and Blessed Land", and then he felt completely different.

How to put it, it's a bit complicated.

Anyway, the previous understanding began to be subverted.

Is there such a possibility, in ancient times, and very early, it can be traced back to before the pre-Qin period, and at that time, there were people and even many people like him, who could see the "breath of the earth and mountains"?

Then, they lived in the mountains for a long time.

Then, there is the reality and concept of "immortal".

And, with the passage of time, this behavior was gradually solidified, and from this, the legend of the cave was born.

But later, whether it is the cave or the blessed land, it seems that it is not as divine as the legend, and this chase gradually cools down, so slowly, it has become a semi-abandoned, non-mainstream existence.

This is a speculation by Xu Guangling today.

But this speculation is no longer confirmed.

And one of the things he will do in the future is to investigate the Kyushu leyline.

And investigate all the caves and blessed lands in the Daozang records, some of these caves and blessed lands, some or even a large part of them may be completely far-fetched by later generations, but Xu Guangling believes that it is very likely that some of them are "cave heavens and blessed lands" in the real sense.

Second, he will inspect all the nameless "longevity villages" in Kyushu.

Longevity villages are not uncommon today, and they are often seen in various news reports, and their common feature is that they are far away from the city, so people also generally believe that the reason for their longevity is to stay away from the city and pollution.

But in ancient times when there was no pollution, did these longevity villages not exist?

Obviously impossible.

Kyushu is so big, how many Changshou villages are there?

Xu Guangling has not yet investigated, but he has preliminarily concluded that most of these longevity villages will be located in places where the "atmosphere of the earth and mountains and rivers" is relatively strong, in other words, most of them are near mountains.

This expedition was listed by Xu Guangling as one of the long-term plans.

Of course, it's not on the agenda yet.

This kind of investigation is just to broaden one's horizons and confirm something, and whether there is one or not is not so important or critical. The key to Xu Guangling's current situation is still to move forward according to the fundamental method, and to move towards the peak step by step from the foundation of the medical Tao.
