Chapter 033 Look at what I am doing

Because dredging involves the geography of tea mountains, the princess called several old tea farmers early on.

They were most familiar with the terrain near the tea mountains and had been staying in the county government office to serve.

The old tea farmer came in with his back bent, bowed his hands and saluted the masters, "I, the old man, greet you all."

"No need to be so polite." Qin Zhaoqiong immediately asked whether there were any unpolluted springs on the undestroyed mountains.

The tea farmer did not answer immediately, but frowned and thought for a moment.

"There used to be one, but the mountain's shape has changed because of the mud dragon. I don't know if it's still there or if it's been polluted. It's also impossible to climb now..."

The princess waved her hand and said, "We have good fighters in our army. As long as it's not a desperate situation, going up the mountain won't be a problem.

Please, old man, lead the way. If we can find a clear spring, it will help alleviate the urgent need in Mingyan County."

“Okay, okay…” The tea farmers naturally all responded in agreement.

He didn't know how to get up the mountain, but when he heard that the soldiers had a way, he had no choice but to agree.

Qin Zhaoyue put forward two suggestions, both of which seemed to have hope of solving the water problem. The atmosphere in the lobby gradually became weird.

Is this still the arrogant, extravagant, and uneducated Sixth Princess?

Soon, all the things needed to purify the water were delivered, and the alchemist Chen Qingxuan finally showed up.

He looked calm and composed, but he was actually very uneasy.

The method of purifying water was clearly taught to him by the Sixth Princess, but she was not allowed to tell anyone.

He had memorized the steps in his mind over the past two days, but he had never actually tried them, so he couldn't help but feel nervous.

"Let's get started."

With more than twenty pairs of eyes staring at him, Chen Qingxuan had no choice but to grit his teeth and go on stage.

First, someone opened a small hole at the bottom of the pottery jar, and then put the charcoal, gravel and fine sand needed for filtering into it in turn.

"Sir, what is the respective proportion?"

When the princess's personal guard asked, the Taoist priest subconsciously turned around and looked at Qin Zhaoyue.

Qin Zhaoyue almost rolled her eyes, "Why are you looking at me? Just speak for yourself!"

Chen Qingxuan was frightened and immediately said that equal amounts would be fine.

The filtration device was ready, and the water used was from the well in the county government office, which was also contaminated.

Everyone was staring at it, and saw that the water dripping from the bottom of the pottery jar had become visibly clearer.

The second step is also the most important alum.

"Sir, how much should I add?"

Under high pressure, Chen Qingxuan looked back again.

Qin Zhaoyue already had the intention to kill. This unfortunate thing kept looking at what she was doing!

Haven't I explained this many times? Why can't you remember it?

"Even though so many people are watching, don't be nervous. If you can succeed, that's great. If you can't, it's not your fault.

Didn't you tell me to add small amounts in batches until there's no more flocculation and precipitation, and then test the ratio?"

"Ah, yes, yes!"

Seeing the Taoist priest's sudden realization, the atmosphere at the scene became even more weird.

Who came up with this method? Why does it seem like the Sixth Princess knows more about it?

Impossible, absolutely impossible!

Yes, it must be that the alchemist was too nervous and afraid of taking responsibility, so this happened.

However, two people had strong doubts.

One of them was the eldest princess. She had a guess in her heart but was not sure.

After all, the skills of a Taoist priest cannot be learned easily, and must be learned from a master.

But she didn't know enough about her sixth sister to know whether it was really her work.

The other one is Sui Mo, who is responsible for close protection, but in the past two days, Her Royal Highness the Sixth Princess has been whispering with the alchemist and the magician.

Although she didn't hear the whole thing, she was 70% to 80% sure that this method of purifying water came from the Sixth Princess!

How many unknown secrets does she still hold? Has she mastered a water purification method unknown even to the Tiangongsi?

There were other discerning people present who had their doubts, but not to the same degree as these two.

Chen Qingxuan felt more confident. Since it was only a small amount and multiple times, he used the medicine scale provided by Tiangongsi to weigh the alum little by little.

When the first small piece of alum was thrown in, flocs really appeared soon.

This happened in front of everyone, witnessed by everyone, and immediately caused a commotion.

Chen Qingxuan heaved a sigh of relief upon seeing this, and then he heard the old man from Tiangongsi say, "Just because there is flocculation and sedimentation, it doesn't mean that the poison can be removed."

In fact, what he said was correct, but no one paid any attention to him. Everyone still had hope in their hearts.

The old man said so, but immediately used paper and pen to record the weight of the alum.

As small amounts of alum were added in batches, more and more flocs were precipitated, and everyone watched closely to see if the flocs would stop increasing.

When the addition was stopped for the eighth time, everyone agreed that no more precipitation would occur.

In other words, the amount added between the seventh and eighth times was appropriate, and the old man from Tiangongsi remembered every stroke very clearly.

If it really works, you need to try again until you find the most reasonable ratio.

Moreover, the water sources are different. Even if the water is drawn from the same well, there will be some differences, which requires multiple comparisons.

Proceed to the next step and use another ceramic jar for three-layer filtration. The final distillation is not difficult either.

It is to boil water, the water vapor enters the bamboo tube through the holes, the bamboo tube is covered with wet linen to condense, and finally the water droplets are collected.

Everyone witnessed the whole process and saw that the condensed water that came out at the end was clean and clear, which gave them greater hope.

"Is this... done?"

It sounds complicated, but it is easy to do. If it works, it can be popularized.

“The water looks clear, but who can guarantee that the toxins have been removed?”

"There's no way to prove it," Qin Zhaoyue said. She wasn't responsible for this. She had used all her high school chemistry knowledge, but she couldn't be sure if it would work. "I said it at the beginning. We need to try to see if it really works."

How to try it? Everyone knows the answer: just let people drink it.

"I'll do it!"

There was another person who just came in with the old tea farmer. His family is seriously short of water. If this method works...

One person is not enough, and he cannot be a strong and healthy person.

Finally, we found ten people who were severely dehydrated or had mild symptoms. We didn't spend any time searching at all, as we caught a lot of them on the streets.

I just explained to them that the water might contain toxins, but seeing such clear water, no one could hold back and they jumped in immediately.

If everyone hadn't stopped them, they would have fought.

Finally, the guards held the man on each side and watched him drink the full glass of water.

After observing for an incense stick of time, nothing happened.

"Very good!"

Everyone was excited and looked at the alchemist Chen Qingxuan.

That day, the old man from the Engineering Company carefully put away his paper and pen and bowed deeply to him.

Although this old man was picky, he was still reasonable. Qin Zhaoyue's impression of him changed a little.

This is just like the technical jobs in the previous life, where I devoted myself to the technology.

As long as the skills are good enough, you will get corresponding respect. Such people are more pure.

Forget it, Qin Zhaoyue thought to herself, I won’t make any arrangements for Old Deng for the time being.

But how could Chen Qingxuan dare to accept such a grand gift, as the other party was an official of the Six Departments.

As for him? He was at best a staff member, of no rank or rank, not even a minor official.

Besides, this matter was instructed by the princess, what does it have to do with him? He dare not take credit for it.

Chen Qingxuan quickly dodged and looked at Qin Zhaoyue for the third time.

Qin Zhaoyue rubbed his forehead helplessly, "Don't worry, your contribution to the water purification method is a credit, and you will definitely be included in the list of merits.

When the disaster relief work is complete, the lords will commend you for your achievements after returning to the capital."

"No, no, it's all thanks to Your Highness."

"Well, I also have some merit in recommending you."

"this……"

Qin Zhaoyue narrowed his eyes, and Chen Qingxuan suddenly dared not speak and could only silently accept the credit.

The atmosphere became weird again. Except for a few people who didn't understand what was going on, everyone else in the room had some guesses, but they didn't dare to believe it.

Qin Zhaoqiong was speechless for a moment. Her sixth sister had just arrived and solved the big problem that had troubled her for two days.

This is true whether the method comes from her or from one of her staff alchemists.

Before I could thank him, I heard Qin Zhaoyue speak again:

"Eldest sister, I want to go see those critically ill patients..."
