The value of purified water goes far beyond drinking, it is also the most important thing in medicine.

In ancient times, there was no sterile environment and really clean water, and using this pure water to disinfect and wipe wounds can be said to save many lives.

Especially in ancient wars, there were not many soldiers killed on the spot, and more died of recurrent wound infection.

Washing wounds and medical equipment with purified water will definitely improve the situation.

Jingyang County Ling came over at this time and bowed his hand to Chen Chu: "Lord Chen, we don't have much drinking water, and it may be difficult to find a water source within a radius of dozens of miles, what should we do?" ”

"No water?" Chen Chu smiled, I have!

Because there were tens of thousands of soldiers who were young and strong, Chen Chu had no way to prepare food for them like he did for the Xiao Cavalry Guards, but if it was just water, it would be easy to solve.

He took the bucket of pure water down from the carriage, and Su Dingfang hurriedly walked over to catch it heavily, a little surprised, he really didn't expect Lord Chen to be so thoughtful in preparing for the trip.

Forty pounds of water, and this bucket ...... It turned out to be transparent!

There are unbelievable materials for filling water, Su Dingfang sighed, Lord Chen is really unfathomable.

"You guys get some people to come over, I'm going to have some water, and the water we have is enough to last for a while."

Chen Chu said and got into a carriage behind, got into the carriage and carried a bucket of water out and handed it to them.

He kept exchanging barrels and barrels, and then brought them out to everyone, making people mistakenly think that the car was full of these things.

Anyway, Chen Chu's convoy was watched by the family, and Su Dingfang and the others never dared to ask here.

"Thirty barrels, more than a thousand catties."

Jingyang County Ling calculated for a moment, breathed a sigh of relief, and smiled.

He didn't know about Chang'an, but he had heard many soldiers of the cavalry guard say that this Lord Chen was a strange person in Chang'an City, and he saw it today.

"I might as well tell you, this water is called pure water, which is clearer and cleaner than the sweet springs anywhere in Datang, so clean that you can't see the slightest trace of dirt and dust."

"It can be drunk directly without worrying about eating it and having diarrhea."

"When used in wound treatment, it can also avoid bacterial infection and wound deterioration, and it is the best clean water source."

Listening to Chen Chu's words, Su Dingfang decided that there would be no problem with what he said at the beginning.

Because looking through the bucket, the water inside was so clean that with his keen eyesight, he couldn't see a trace of dust and dirt.

Presumably it must be very sweet to drink, thinking of this, Su Dingfang couldn't help but swallow his throat.

But when he heard the last sentence, his heart moved.

"Master Chen, is there anything particular about the treatment of this wound? Why is clean water good at preventing germ infections? ”

Chen Chu smiled: "You guys prepare dinner first, and I'll tell you while eating." ”

There was nothing special for dinner, but Chen Chu still vigorously promoted the way to eat fried locusts, firstly, to increase the taste of food, and secondly, to let everyone know that this locust is nothing more than this, it can harm crops, and people can also make it delicious to retaliate.

Pepper and five-spice powder have been used up in more than ten simple seasoning boxes, and the tomato sauce, bean paste, and the like have been accumulated inside, these things can't be stored for a long time, Chen Chu pondered and tried to use them up as much as possible tomorrow morning.

Su Dingfang took some officers to live in the same place with Chen Chu and sat down to eat.

Because Datang's usual food taste is too bad, Chen Chu didn't move his chopsticks much, anyway, he went back to the carriage for a while, changed the plate and patted the cucumber, and drank beer on the hour.

"Actually, the water you usually see is also very dirty, and if you look closely, you can see that there are a lot of fine particles in it, and those are dust and dirt."

"There are countless things smaller than this dust and dirt, densely hidden in the water."

"In the air, on people's bodies, and even in people's bodies, there are these dense things, which are called bacteria, and usually food spoils and corpses decay, and it is because these bacteria have changed that these phenomena are caused."

Chen Chu used as simple words as possible to explain to everyone, mainly to Su Dingfang.

Chen Chu originally thought that he couldn't understand, but who knew that Su Dingfang nodded solemnly.

"Lord Chen, I once observed the water I drink, and I did find that there was dirt in it anyway, even if it was your water, Lord Chen, I could see very fine impurities when I stared at it."

"But the water is much cleaner than I've usually seen, as its name suggests, it's as pure as the sky."

Su Dingfang couldn't understand the so-called bacteria or anything, and when he saw the pure water up to now, he realized that the water used by the wounded soldiers to clean their wounds turned out to be so dirty.

"So the more you deal with the wound, the more it often backfires, and the wound not only does not have it under control, but it worsens and becomes infected."

"It's because water can't clean the wound, and you can't wash the bandages and other things that treat the wound, so the bacteria get into the wound, you know."

Su Dingfang nodded, looking at the bucket that was being dismantled, his eyes showing fire.

If these things were in the army, the lives of the brothers would definitely be saved, right?

When the water was unpacked and poured into a mouthful of bowls, Su Dingfang took a light breath and smelled the sweetness of his imagination.

The taste alone was sweet, and he had not encountered anything like it except for a few times in his lifetime when he passed by the real sweet spring water.

He took a sip lightly, fearing that drinking too much would cause waste.

A sweet taste exploded into my mind, poured into my heart, and spread to my limbs!

It's so clean, it's so cool, it's so sweet!

And this sweet taste is delicate and long, from the moment it is in his mouth, to the moment it has completely disappeared in his mouth, it will remain for a long time, and he feels that his whole mouth has become fragrant.

This is the real water!

It's worthy of the word pure!

If this is not pure, what water in the world could be cleaner than it?

Su Dingfang has tasted the taste of ice and snow melt and snow water, and to be honest, he doesn't see much clean, after all, there are fish, animals, birds, and dust and mud and sand in the water.

After a few sips, when he came back to his senses, he found that his cheeks were wet, and tears flowed down at some point.

Some of the other officers reacted almost identically to him, and Chen Chu was dumbfounded.

Damn, I know how good and clean this pure water is, in fact, many modern people have a similar reaction when they drink this thing for the first time.

It's just that they drink too much pure water, and it is difficult to have such an obvious feeling of conflict later, but the sweetness can still be vaguely felt.

The ancients never had such good drinking conditions...... It seems like that's normal too?

After Chen Chu complained, forget it, don't look at your jokes, brother go back and open a small stove to deal with dinner.
