Seeing Li Ke throwing unknown objects into the water and stirring, this kid's behavior like a family even the guards on the side were a little puzzled.

"Your Highness, why are you constantly stirring this spring water, is there something wrong with this water?" Yuan Kui saw that Li Ke was still stirring, so he stepped forward and wanted to take the bamboo piece in Li Ke's hand to let him come, but Li Ke refused.

Li Ke was also relieved to see that the particulate sediment and suspended matter in the water were slowly deposited, and the method that the field guide said in his previous life was really useful.

In later generations, people generally drank water after disinfection and purification of waterworks in the city, and then those with higher requirements would generally be filtered and drunk with a direct drinking water device, or a water dispenser with activated carbon was installed to heat, and no matter how bad it was, it should be boiled and drunk. In the wild, alum or water purification tablets are generally used to purify water, the principle is that these two things will become sponge-like colloids after being dissolved in water, and then continue to absorb the fine particles and germs invisible to the naked eye in the water, and finally settle at the bottom of the water to achieve the effect of water purification.

You must know that even the mountain spring water is not 100% clean, if it is really clean, then there is no need to build any 100,000-level purification filtration equipment for a certain spring in the future, just carry it as their advertising slogan says?

The method that Li Ke knew was told to him by a guide in the process of studying desert spices in his previous life, because the juice of cacti also has colloidal properties, and the mucus has an electric charge after entering the water, which can adsorb small particles of sediment and suspended solids and most of the bacteria in the water to achieve the effect of water purification, and there is no chemical alum or the additional taste of the pill after water purification, but it has a slight freshness of plants.

Li Ke, who has solved the problem of drinking water, is in a good mood and can finally stop worrying about the water problem.

But Li Ke still didn't take it lightly, ostensibly to solve the problem of drinking water, but who knows if this trip will cause more trouble.

。。。。。。。。。。。。。。

Furong Imperial Garden, in the side hall of Ziyun Building, it is noon, but because of the poor lighting in the palace, countless palace lamps are lit, and the little son sits on the seat away from the fireworks and looks at the east of the hall in a daze, as if the exquisite furnishings and gorgeous decorations in the palace are no longer in the eyes.

"Brother Prince, why hasn't the third brother come back yet, is there no lunch today?" The little son looked east and said to Li Chengqian, who was sitting at the top.

"This, Brother Ke may have something important to do, Mingda is okay to wait." Li Chengqian accompanied the smiling face, but he also muttered in his heart, why didn't Li Ke come to eat.

At this time, there was a sound of horses' hooves outside, and the horse's hooves rumbled like thunder, and the little son's big eyes blinked, and he wanted to trot out to have a look, only to see a hearty laugh outside.

"It's my father." Li Chengqian also followed the little son out of the hall when he heard the laughter, and greeted Lao Li with a few younger brothers and sisters.

When Li Chengqian came out to take a look, Lao Li, who was surrounded by a group of knights, took the little son who was rubbing his tears in his arms with a stride, and was smiling and wiping away the tears for the little son.

"My little son doesn't cry, isn't my father here to accompany you?" Lao Li lovingly coaxed the little son-in-law, as if only the little son-in-law was left in his eyes.

"I've seen my father," Li Chengqian took Changle and King Jin to salute Lao Li. saw that Lao Li did not come alone, at this time, Gao Yang and Li Suzheng stood on the side of Lao Li like a good wealth boy.

"I've seen the prince's brother" The lively Gao Yang saw that no one was outside, and said with a smile.

"Well, get up, have you had lunch?" Lao Li smiled, seeing that Li Ke, the master, was not there, he then asked, "What about Ke'er, why didn't you come out?" ”

"The third brother is busy today, but he doesn't know where he is, but he made an appointment with us to have lunch in the Ziyun Building, and he should be there soon." Among these princes, Li Chengqian is the largest and has the most right to speak.

"That means there's no food? Just together. Lao Li waved his hand, his sharp eyes converged, and he glanced at Li Chengqian, who was standing in the center, and then commanded the servants of Li Ke's mansion to prepare lunch domineeringly.

All the princes and princesses followed Lao Li into the main hall, sitting on both sides, only to see the princes seated on the dining table as usual, all the princes and princesses are habitually sitting on the ground, but the main case of Lao Li sitting is a little unusual, only to see a strange wood crop in the middle of the dining table, which makes people feel strange.

Manager Wang, who was beside Lao Li, was sharp-eyed and quick-witted, and wanted to move this thing away, but was immediately stopped by Lao Li's look. The well-informed Lao Li had never seen such a peculiar wooden tool, so he had the heart to test everyone present.

"Does anyone know the name and purpose of this thing?" Lao Li pointed to the strange wooden tools beside him and asked with a smile.

Everyone also thought that this wooden tool was particularly peculiar, but they couldn't think of what it was used for.

The princes and princesses exchanged heads, but none of them answered Lao Li's question out loud, and the atmosphere suddenly became awkward.

Princess Changle, who came to Furong Garden to recuperate, glanced at the height of the little son, and looked at the height of the strange wood from the side, Li Lizhi of Hui Lanxin immediately had an idea, and said warmly: "Erchen thinks that this thing is for his daughter's family to groom. ”

As soon as this remark came out, everyone in the hall was even more puzzled, how to have something to do with dressing, isn't there a dresser for dressing, but the important thing is that the dressing table is not as high as half a zhang, if you use this thing to make up, do you have to squat or bend over to make up?

Seeing that everyone was dazzled by what she said, Princess Lizhi also smiled and answered for everyone, "The general dresser is naturally not so high, but what if it is for Mingda?" ”

The little son was drinking goat's milk at this time, and she was not interested in the things on the dresser, but when she saw Sister Lizhi mention her, she noticed the strange wooden utensils next to Lao Li, and then asked a little shyly: "Is this really for Mingda to comb ,,,?" ”

Everyone laughed, it seems that although the little son has not yet reached the line, he already knows the meaning of dressing up.

Lao Li smiled and beckoned to the little son, "Little son, come and try it by my father's side." ”

The little boy trotted all the way and stood in front of the chair, the height of the child just corresponded to the chair surface of the chair, if a bronze mirror was placed obliquely on it, wouldn't it correspond to the little child's little face?

All the princes and princesses praised Changle's statement, and even Lao Li squinted and smiled, and Li Ke was thoughtful.

At this time, Li Ke had arrived in front of the hall, seeing that the atmosphere in the hall was warm, everyone was talking and laughing around Li Ke's chair, and the little man in front of the chair looked left and right at Li Ke's chair, as if he was considering the position of the wooden utensils.

"Erchen has seen his father, what is his father?" Li Ke was busy saluting Lao Li, after all, the sky and the earth are big, and Lao Li is the biggest.

"You've just arrived, and I'm about to compliment you on preparing such a wonderful thing for your little son. In the past, I was negligent and didn't have the right equipment for my little son. Lao Li blamed himself a little, after all, a father with a child will inevitably be a little incomplete, and the things to consider will be different from the perspective of a mother with a child, not to mention that Lao Li has a lot of government affairs, and he has no time to think about these.

Li Ke couldn't help but be a little puzzled, when will I prepare a chair for the little son? I've put this chair here to show you how to sit on it or not.

"Ahem, father, this thing is called a chair, the left wood and the right strange chair, but it is not specially used for the little son, it is used to sit." Li Ke hesitated for a long time, but still said the correct way to open the chair, and said quietly.
