In fact, of course, the empty monk also wanted to continue listening.

So even if he was "squeezed" by Song Ziyu lightly, he didn't make a sound, but looked at Lu Yu with blank eyes.

Although he couldn't make good tea, he also had a strong interest in tea because of the continuous edification of the old monk and the nostalgia for the Yuhua tea he once drunk.

In fact, when Lu Yu took out a bag of tea, the most anxious among the three to taste was probably the empty monk!

He hasn't drunk proper tea for more than 40 years, and the "gluttony" in his stomach has long been hooked.

Lu Yu nodded approvingly at Song Ziyu, and then said slowly: "Okay, then I'll briefly talk about the water for brewing tea." ”

He looked up at the sky and said leisurely, "As I said just now, rain and snow water are naturally soft water, and it stands to reason that this should be the most suitable water for making tea." But I don't exactly recommend using this water to make tea. ”

"Why?!" The empty monk couldn't help but ask.

Lu Yu smiled lightly: "Rain and snow water, in ancient China, was called 'Tianshui', which means water given by God, especially snow water, the snow water is pure and flawless to melt and then boiled water to make tea, the taste is almost indescribable in words, and even the tea has not yet reached the mouth can already feel the sweetness and freshness." ”

"In comparison, rain is a little less than that, because it can be surprising depending on the season."

"Generally speaking, autumn rain prevails in the rain. Because the air is crisp in autumn, there are fewer dust and impurities, and the taste of water is clear, which is the best in the rain, and it is not bad to properly store it if there are conditions. ”

"The rain in spring is dull because of the rainy season, and the taste is sweet but smooth, just because there are fewer impurities."

"As for the summer rainstorms, the water quality is the worst, so it is not suitable for drinking."

"The reason why I don't particularly recommend rain and snow water is because in addition to their extreme inaccessibility, but also because air pollution is very serious nowadays, especially near cities with heavy industry or chemical industry, there are too many heavy metals and harmful substances in the water, and it is harmful to breathe into the body, let alone drink."

"But if you insist on drinking rain and snow water, then I recommend taking water just and not taking the first shower of rain or snow, because the first shower of rain and snow has more dust in the air, which is not only harmful to the taste but also harmful to health. If you can get the second shower of rain and snow in a place where the mountains and rivers are beautiful, that is the best. ”

Seeing that the two of them nodded in understanding.

Lu Yu also did not pause, and continued: "Secondly, I will talk about mountains and springs. ”

"The reason why mountains and springs are put together is that most of their water sources come from rocky mountains, which are densely vegetated, rich in a variety of trace elements that are beneficial to people, and filtered by sand and gravel, the water is clear and luscious, and contains very little chloride."

"Coupled with the natural flow of living water, the water can fully absorb fresh air and be converted into soft water after boiling. Therefore, it is definitely the best choice for making tea with good color and flavor! ”

The empty monk glanced at the deep pool not far away and said, "So what you recommend is mountains and springs?" ”

Lu Yu nodded, but shook his head again: "If it's here, or if it's the top of Zhenlei Mountain that I've been to, then I naturally recommend the water of the mountain spring." But if it is changed elsewhere, it is not easy to say. ”

"Therefore, the mountain spring water should vary according to the specific location, and blind recommendation will only harm people."

The empty monk smiled disdainfully: "Can drinking mountain springs still harm people?" ”

Lu Yu said: "Why don't you hurt people? It is even possible to suffer arsenic! ”

"I am not sensational, and not to mention the sulphur springs and other springs that contain minerals such as heavy iron, that is, the springs with rushing waterfalls and the springs that do not flow are not drinkable."

"Most of the rushing water comes and goes quickly, for the rapids. Torrent water must have its own source of water, which tends to aggregate very quickly and come from different sources. Among them, it is turbid and difficult to distinguish, and drinking it is harmful and useless. ”

"The water that does not flow is better understood, the stagnant water is a pool without waves and waves, and there is no substitute for Xie, who knows what it will leave under the water for thousands of years?"

"So if it is recommended, I only recommend the water of the mountain spring where the stone pond is flowing and the composition of the water is determined, and the water of the other mountains and springs is not recommended."

Lu Yu paused, and then said directly: "Besides, I'll talk about the water of rivers, rivers, and lakes. ”

"These waters belong to the earth, and it is fine if they are pure near their source, or in ancient times when there was no industry. However, in today's world, both air and water sources have been polluted to varying degrees, and the overall brewing effect is slightly worse than that of spring water, so it is not recommended to use it directly. ”

After finishing speaking, Lu Yu groaned slightly and said, "Next, let's talk about the well water." ”

"The reason why I have singled out well water is because it was the most commonly used water before modern times, and also because well water is a shallow surface water."

"The taste of brewing tea with it can only be said to be acceptable, of course, this does not rule out that some wells with excellent water quality are very suitable for making tea. There are countless wells in the world, and the quality of well water varies greatly from place to place. ”

"But in general, well water is not particularly recommended, or for the same reason, the modern world is so polluted that who can guarantee that the local shallow water sources are still clean?"

Lu Yu smiled and said: "As for the tap water of every household, not to mention, the tap water has been mixed with chlorine for disinfection when it is filtered, and there is a lot of iron, which is harmful to drink raw, let alone make tea." ”

"Therefore, in today's world, in addition to the occasional water of mountains and springs, the water of rain and snow in the ethereal land, and the water of the rivers in the pure land, I prefer to use the pure water and neutral mineral water that is readily available to make tea."

Speaking of this, Lu Yu suddenly sighed and said: "Although the world is now technologically advanced and everything is progressing, it is precisely because of this that it is becoming more and more difficult to find a quiet place to make a cup of tranquil tea...... No matter how delicate the water is, how can it be compared to the natural water? ”

As he spoke, he glanced at the kettle above the fire and said lightly, "Don't say more!" Empty monk, the water has been boiled, why don't you hurry up and bring me tea. ”

Lu Yu's "Theory of Water" had already made Monk Kong's heart shake when he heard this, and he couldn't help but be stunned when he heard this, and then he forgot the relationship between himself and Lu Yu, and turned around to fetch the kettle that had just begun to boil slightly.

After the kettle was carefully served, Lu Yu smiled slightly: "Okay, go get a few cups." ”

It was only at this time that the empty monk reacted, and he couldn't help but blush and said, "Little guy! On what basis do you command me? Are you really your henchman? ”
