A few days Jiang Tian drummed out of the things in front of the shopkeeper Zhao, from the appearance it looks like a crude pottery broken jar, said that it is broken because there is a hole in the bottom edge of the jar, although the break is not big, but you can see the cotton wool stuffed inside, for a container absolutely belongs to the ranks of scrapped.

"This ......" Boss Zhao was a little unsure: "Can you make bitter water sweet?" ”

Jiang Tian nodded first and then shook his head: "It can't be sweet for the time being, but at least it can be drunk." ”

I saw that he found a larger jar, and then found a few pairs of chopsticks to put the broken jar on top of the good jar, and finally poured the boiling bitter water into the broken jar, one scoop, two scoops...... Until the bottom of the jar began to seep water, and then he took a bowl of filtered water and handed it to Shopkeeper Zhao.

The old man hesitated to take it, to see that there was nothing unusual about the water in the white porcelain bowl, and then looked at the jar that was still seeping, and looked for the other party to poison himself even if he would not spend so much Zhou Zhang, so he drank the water in one go. Jiang Tian stared at the old man's reaction from the side, only to see him frown and then put down the bowl.

The old man carefully smashed the taste: "This water can indeed be drunk!" It's just that the taste is still a little bitter. ”

Jiang Tian thought to himself that I would like to be able to get pure water directly, and it is already the limit to use simple charcoal filtration, and there is no magnet at hand to absorb heavy metals, which is still the result of pouring boiling water into it, and if I filter the well water directly, the taste will be stronger. In other words, if you want to get pure water this year, there is only one way to distill, the structure of the distillation equipment is also very simple, everyone who has eaten Yunnan steam pot chicken understands what the principle is, but the fuel in Beijing is not for nothing, and the efficiency of distillation is too low cost and too high, which is not suitable for the use of this small family.

"Shopkeeper, I want to use this water to make tea that ordinary people can't drink, so I can save a lot of water money!"

Jiang Tian thought that he had come up with a good way to save costs, but he knew that the old man, who was still a little surprised, changed his expression in an instant: "No!" This water will definitely ruin the taste of tea, how can it be lost because of a small loss! ”

In this way, Jiang Tian's first invention after crossing was directly denied by the old man, although many people in later generations regarded this as Zhao's shopkeeper stubbornly conservative, but some people praised him for his honest business. No matter how you evaluate him, at least everyone agrees that the world's No. 1 inventor has shown extraordinary talent at this moment, and it is the beginning of China's 300 years of leaving Europe and being proud of the world.

Jiang Tian is not so great at this moment, his original intention is to save expenses, not to mention that this purpose is at least partially achieved, although the filtered water cannot be sold as shoddy, but at least it can be kept for his own drinking, Shopkeeper Zhao did not hesitate to drink this kind of water, saving a person's water is also a little contribution to saving expenses. He also secretly lifted the white cloth on the top of the jar more than once to peep, but he saw nothing but layers of charcoal and cotton wool, could this be the secret of making water drinkable?

In this way, a few days later, the three coveted beauties came to the teahouse to drink tea again, because they had not seen each other for many days, Jiang Tian had long forgotten the existence of this person, and now he was thinking about how to make money in addition to looking forward to the storyteller every day to quickly change the story. So at first glance, I didn't recognize this guy in a daze, which is definitely a dereliction of duty for a shopkeeper.

"The three of you, please, dare to ask what kind of tea the son likes?"

The couple exchanged glances, and said in their hearts, you have such a bad memory! At the beginning, I ran away like a plague god, and I forgot about us in just a few days? The pervert led by Liu had a plan at first sight and wanted to tease the other party.

"Shopkeeper, pick up your good tea here and serve a pot, I'll taste it first."

Looking at this pretentious appearance, Jiang Tian seemed to remember who the other party was, but he couldn't fully remember them, and he still asked dutifully with doubts: "There is a dragon well in our store, can the three sons come to a pot?" ”

The scholar surnamed Tian nodded, he believed that Jiang Tian had indeed forgotten about them, in addition to lamenting that this shopkeeper was unqualified, he was also sure that the other party did not take himself in his eyes at all. This is an absolute shame for people who think very highly of themselves.

Taking advantage of Jiang Tian's time to serve tea, the surnamed Tian turned his head and said to his two friends: "You see, it's only been a few days, and he doesn't even know us." ”

The son surnamed Song didn't care so much about him: "I think he can't remember that there are many people coming and going, right?" ”

The pervert surnamed Liu muttered in a low voice: "Did you see it, there is an extra broken jar on the counter." ”

As soon as he said this, the two of them noticed that there was an extra piece of ornament on the counter, and the bottom of the jar was still dripping.

The scholar surnamed Tian stared for a while and didn't find anything peculiar: "Maybe it's reluctant to throw it, you see that there is a bowl under it." ”

Song Gongzi shook his head: "I don't look like it, but there is a bit of a copper kettle dripping demeanor." ”

Liu pervert shook his head: "I know this, but this small shop still has to count the hours?" ”

The three of them pondered for a moment, but none of them could figure out what it was. If it was placed in other stores, they would either not care about such a trivial matter, or they would just ask the guys directly, and they would definitely not stay alone and be foolish. But this is not an ordinary shop, this ordinary-looking teahouse can afford to hire a well-known storyteller in the capital, employing a genuine showman to run the hall, and this cameo shopkeeper itself still exudes an elusive and mysterious feeling, with that fluent military hand, it is not comparable to other shows. In fact, as a text used by the ruling class, even if some readers are repulsed, most of the poor talents who need to be "motivated" are still happy to imitate it. However, traditional Chinese characters have long become an insurmountable habit, and on the other hand, there is still no complete simplified dictionary on the market, and no one except those who have been educated in the army dare to guarantee that their writing will be in accordance with the norms. Even if they had the intention to collect characters from some official documents, this was limited to those who had access to such texts, so until now, everyone understood that the current emperor did not want to restore the traditional Chinese characters, but he did not officially promote simplified characters, so the two characters were used in parallel. At this time, someone suddenly discovered that a down-and-out talent actually used half-concealed military characters without hindrance, which itself has become an interesting thing, and the indifference revealed in his speech and demeanor does not have the slightest shame of being humiliated by scholars in the market, but there is a kind of freedom that is not hypocritical. These boys are used to seeing them or tend to be inflammatory, or pretend to be high-minded, and they are also surprised to see such a character who is neither humble nor arrogant.

Saying that, Jiang Tian observed this couple while making tea, and after pondering for a while, he suddenly remembered, his memory is really bad enough It seems that he can't hide today, there is only him in the shop, and now Boss Zhao is not in the store, so he really can't hide.

Seeing Jiang Tian serving himself tea, the highest-ranking pervert brother couldn't help but preemptively ask, "Shopkeeper, what's the use of the broken jars on your counter." ”

Jiang Tian didn't know why he asked this question, but fortunately, it was not something unspeakable, so he replied nonchalantly: "This is a clumsy work, just to filter the bitter water and barely drink it." ”

Song Gongzi, who has always been like a soy sauce party, lit up when he heard this: "Filter the bitter water? Don't talk nonsense! ”

Jiang Tian was too lazy to talk nonsense with them, but the customer was God's own business, and there was no reason to drive the guests away, so he sighed slightly: "Believe it or not, it's just that I said ugly things in front, although the filtered water is drinkable, it is not sweet water." You better don't try it. ”

Although Liu Gongzi is lustful, he is not a fool, he saw his partner's intentions, so he drove to it unhappily: "You go and get busy, you don't need to wait here." ”

When Jiang Tian walked away, Liu Pervert asked Song Gongzi in a low voice: "Brother Xian, what is the meaning of the word 'filter'?" ”

Tian Gongzi shook his head when he heard this, and replied for Song Gongzi: "You don't know how to learn, did you fall asleep again when Feng Xingong explained Xinxue?" ”

Song Gongzi smiled bitterly, and could only explain it to a certain bad student who was confused: "This sentence comes from today's Shengshang, when my ancestor was in Jiangnan Conglong, I heard the Shengshang mention something similar, saying that if you have this thing on the battlefield, you won't have to worry about not getting a clean water source, but you also know that Jiangnan has a lot of water, who needs this thing to help?" I heard that it costs charcoal to make it, and it is not necessary for ordinary people, so it was not widely promoted in the capital. ”

As soon as he heard that it was something mentioned by the emperor, Liu Gongzi's expression became more and more curious, how could this kind of thing, which was only known in a small area, appear in this store? Could it be that the elder of this broken scholar was also a figure in the army back then? But after the change of dynasty, the new son of heaven is more sympathetic to the old ministers, even if he is old, weak, sick, disabled, widowed, and lonely, he can at least enjoy the rest of his life, how can he let his own children and nephews be left behind?

The minds of these two people are similar, there are very few founding kings in Chinese history who can only tear down bridges in the river, Ying Zheng, Li Shimin and the like can only be regarded as a very few, and these two have been prominent before they won the world. So at the beginning, these upstart families compared the lessons of the early Ming Dynasty, and they have been trembling for fear of becoming the first birds, leaving an excuse for today's long live rabbits and dead dogs. Seeing this strange shopkeeper, I can't help but be vigilant, in case a small family that is not very prominent has been killed, but the news has been covered up without leaving a trace, wouldn't it be ignorant of the impending disaster?

Thinking of this, Liu Gongzi, who seemed to be vulgar, asked in a low voice: "Brother Tian said that there must be a lot of charcoal in this thing?" ”

The other party nodded, and understood his thoughts.

Liu Gongzi saw that Jiang Tian's attention was not here for the time being, so he stood up and walked quickly to the counter, then reached out and opened the cotton cloth that should be at the entrance of the altar, just took a look at it and then recovered and sat back again, and after taking a deep breath, he nodded slowly. The other two couldn't help but glance at each other, there are very few people who know this kind of thing, except for the parties back then, there are only those Xun Qi children in the academy, and most of them are not easy to learn like Liu Gongzi, so at this time it is more and more strange, unless this Xiucai is really talented and has the same magical powers as today's saints, there is only one explanation left...... This person must have some kind of connection with the royal family!

Thinking of this, the three students made eye contact, and invariably stood up and clasped their fists in each other's form and saluted.

It was the pervert Liu who spoke first: "It's unfortunate today, the little brother remembered that his family was strict and had a life, so he went down to do a private matter, so he had to leave it for the time being." ”

Song Gongzi also got off the donkey down the slope: "If this is the case, I just want to ask my ancestors about some things in my studies, and I will also leave." ”

Tian Gongzi said with a blank face: "Isn't it boring that you are all gone, and only me is left?" Homecoming, homecoming. ”

Jiang Tian picked up a dime of silver thrown on the table while cleaning up their cold tea, thinking that these boys are really a loser, this seems to be enough for a tael of silver, but this small shop is a net profit for ten days! If they come a few more times, they don't have to greet other guests. So far, Jiang Tian still doesn't know what kind of chain reaction his unintentional move has triggered.
