What Liu Bei said was the truth.

In later generations, the pollution was serious, and masks were required to go out, so there was a lot of research. The service life of activated carbon is not calculated by time, but by the amount of adsorbate. It depends on how to use it and how much it is filtered.

Filled with dirt, he will die of his life. If the air is cloudy and there are too many filters, it will need to be replaced every day. However, in very clean condition, the activated charcoal pack can last for a full year.

So, what is the air of this era?

The answer is, it's clean!

Always use tiger bones, not to mention Liu Bei, even tigers can't afford to consume them. Then he whispered to Geng Yong about the general method of burning bamboo charcoal.

Geng is good at firing. Even if Liu Bei only said a general direction, the furnace craftsmen could figure out the firing method.

As the saying goes, in troubled times, heavy canons are used, and strong medicines are used in emergencies. The first dose or two of medicine is a fierce medicine. The effect of the drug is excellent. In the future, if you consider decreasing, you will naturally not need to use tiger bones. Liu Bei had even thought of what he said.

Geng Yong is an eye-opener every time he comes.

With the charcoal grilling method in mind, I took my leave and left.

The nose is all covered by a black lacquer mask, revealing only a pair of ghostly big eyes, which is very attractive.

After no longer inhaling inhalations such as dust mites, pollen, fungi, and animal dander, which can induce disease, the whole person is much more active. This is the naughtiness that should be at this age. mingle with Liu Bei, Su Shuang, and the Liu clan brothers of the same age. Although he is the smallest, he has good bones and great strength. He was nicknamed 'Running Bull' by his friends.

Suber also liked it very much. So I secretly thought about creating a mask for Huang Xu that was doubly easy to use.

Knowing that the 'beast bone mine blood medicine' was expensive, Huang Zhong recommended himself and became Liu Bei's guard with a knife. The family also moved into the guest room in the front yard of Liu Bei's house.

The Gongsun clan is in the center and protects his mother. Huang Zhong was in front of the house, sweeping the night. There was also a female assassin who popped up in the backyard from time to time, and Liu Bei finally slept more soundly.

After finishing Huang Xu's affairs, Liu Bei came to Guo Zhi, who lived here, to talk in detail.

It turned out that Nanyang Guo sent Guo Zhi to come in order to exchange the skills of brewing Jiuyu Spring Wine for the production skills of Lou Sang hemp mats.

Why not!

Liu Bei agreed. Guo Zhi took out the coupon book, Liu Bei read it carefully, and there was nothing wrong, so he signed it. As the saying goes, there is no basis for words, but all transactions can be thought of signing a coupon first, which shows that the Chinese law is deeply rooted in the hearts of the people.

Now that the coupon has been signed, how can Guo Zhi hide his secrets.

Then he found a good craftsman and asked for it according to the map. Brewing vessels.

The design of the wine garden also referred to Guo Zhi's suggestion and made some modifications. But where does the good water come from?

Go find it!

Liu Bei remembered that the reason why Zhuozhou Gongmi was famous all over the world in later generations was precisely because of the irrigation with underground sweet springs.

Where does the sweet spring come from?

Asked the third uncle. The third uncle said that there is a thousand-year-old pine tree in the depths of the wild forest. The ancient trees are towering and vigorous. There is a clear spring, gurgling from under the roots. Sweet and pleasant, drink and forget your worries. Liu Bei was overjoyed, and this called Guo Zhi and the third uncle and Huang Zhong to go deep into the wild forest. I found Honka and Ganquan.

I saw the sweet spring coming down along the roots of the tree, meandering into the clear stream. Guo Zhi said, violent destruction of heavenly things.

So he asked people to build a grass house under Panasonic, build a pond to store water, and send it to the wine bar.

The children of the clan and the newly attached people elect their excellent ones to learn from their teachers. Follow Guo Zhi and learn the brewing skills.

Guo Zhi also sent a message to the Nanyang clan and sent people to learn the skills of hemp mats.

Liu Bei also arranged for the Guo clan to go into the dormitory and learn how to make mats.

Just as Liu Bei is not worried about the hemp mat being copied. In this day and age, fame is sometimes really important. Think about celebrities who are half cheaper to buy officials. The mat that was supposed to be dismantled and knew the trick, but it had to be sent to learn with great fanfare. This is called 'the teacher is famous'.

I thought it was the most difficult wine, but I was the first to make it. The front and back courtyards are three-story heavy buildings. Hospitality in the front, sake brewing in the back. There are shops, private seats, and private rooms. The liquor sold by Danglang is a new specialty of Lousang brewed by the Nine Brewing Method: Songquan Brewing.

Before planting, Liu Bei's more than 100 acres of seedlings were divided into Zongren, and mulberry was planted all over the building. From a distance, Lousang Village is like a fortress in the water, surrounded by green grasses.

This is the most important time of the year. Except for the production of bedding mats and the laying of the roadway in the village, all civil works have been suspended. Liu Bei also drew a picture and asked the craftsmen to make rice horses to assist the clansmen and the people to plant rice. The horse resembles a small boat, with its head and tail cocked, and can be ridden by one person. The operator sits on the back of the boat. If you are planting rice, insert the seedlings in the bow of the boat into the field by hand, and then gradually move the horse backwards with your feet. If the seedlings are pulled, the seedlings are plucked with both hands, tied into turns, and placed in the rear warehouse of the ship. It can not only improve the efficiency, but also reduce the labor.

Zhuoxian Qilinzi, the name of Lousang Liu Shaojun, is widely spread among the attached people.

After Liu Bei's repeated experiments, the measurement of activated carbon packets in Huang Xu's protective mask was successfully estimated.

From the original full bamboo tube, it has become a thin tablet with only an inch. The mask has also been modified accordingly. The wooden mask was replaced by a softer, more form-fitting leather. The filter gasket is supported by thin steel sheets at the front and back. The principle is the same as that of a hairpin. When you break it back, the steel sheet opens on its own and the gasket can be removed. After replacing the new pad, break it forward, and the steel sheet will fit by itself and jam the filter. The entire filter element is cleverly designed to be easily removed and replaced.

The key is that it is easier to breathe when it is thinner. After being ill for a long time, Huang Xu stopped wheezing and often forcibly held his breath. How long has it been since I breathed so well?

After the breath flowed, it felt like the whole world was different.

The powerful genes accumulated in Huang Xu's body have attributes. Three-year-old looks big. The old patriarch said, "It must be a tiger."

The little changes in the only son, Huang Zhong and his wife both saw it. Shaojun Liu Bei treats people with sincerity, which is even rarer. Huang Zhong hated not being able to do his best. Wandering around the village all day with a knife, his body was full of murderous energy, and even wild dogs did not dare to approach.

Liu Bei scratched his head. asked the old patriarch to call all the young and strong people in the village who practiced martial arts.

It was compiled into a 'part' and handed over to Huang Zhong for practice.

At this time, the private armament of the powerful landlord had not yet been made public.

waited until the Yellow Turban Rebellion, and the villagers who were suffering from the war, avoided the powerful families of the world one after another. In order to gather the crowd to protect themselves, the powerful people of the world compiled their clans, guests, house slaves, protégés, and former officials into a trilogy. The trilogy has become a general name for the powerful private armed forces of the world. Also known as a family soldier. In wartime, it is a part, and in peacetime it is labor.

In terms of archery, here and now, Huang Zhong is almost an enemy.

War bows are not in a hurry to buy first. With a slight modification of the hunting bows of each family, it is sufficient.

Liu Bei also worshipped Huang Zhong as his teacher and learned battlefield archery. Previously, the third uncle taught Liu Bei the art of hunting. Shooting people and beasts is very different. However, with the foundation laid when he was young, Liu Bei got started quickly.

Seeing that he was inferior to his horse, Liu Bei asked Su Shuang to bring a full-year-old jujube red horse and give it to Huang Zhong.

Twenty gold is a good horse, and fifty gold is a good horse. After a winter, the jujube red horse was fed by Su Shuang for a full year, and it was quite a treasure horse.

I saw it, with a high head and a long neck, strong limbs, a long mane and a neck, and a fur like fire, knocking iron hooves from time to time, making a galloping shape. Sure enough, it is a hybrid of Dawan horses and Hun horses. Good stamina, strong weight, good at sprinting. It is the best choice to do rangers and iron rides.

Huang Zhong loved it deeply and named it Longjiao.

A horse over six feet is a horse, seven feet or more is a horse, and eight feet or more is a dragon. Spark, too. Jujube red horse is as its name suggests.
