Liu Bei said the truth.

Later generations were severely polluted and needed to wear a mask when going out, so it was quite researched. The service life of activated carbon is not based on time, but on the amount of adsorbents. It depends on how to use it and how much filtered it is.

If you suck up dirt, you will die. If the air is turbid and there are many filtered things, you need to change it in one day. However, in a very clean situation, activated carbon bags can last for a year.

So, what is the air of this era?

The answer is, very clean!

He always uses tiger bones, let alone Liu Bei, even tigers cannot afford it. So he whispered to Geng Yong the general method of burning bamboo charcoal.

Geng was good at firing. Even if Liu Bei only mentioned a general direction, the furnace maker could figure out how to firing.

As the saying goes, use severe pennants in troubled times, and use strong medicines for urgent illnesses. The initial one or two doses of medicine are strong medicines. The effect of the medicine should be very good. If you consider it in the future, you will naturally no longer need to use tiger bones. Liu Bei has even thought about the words.

Geng Yong's eyes are very open every time he comes.

I kept the roasting method of bamboo charcoal silently in my heart, so I said goodbye and left.

The yellow Xu, whose nose is covered by a black paint mask, only reveals a pair of weird big eyes, is very popular.

After no longer inhaling dust mites, pollen, fungi, animal dandruff and other inhalations that can induce diseases, the whole person became much more active. This is the naughty that this age should be. He is a match with Liu Bei, Su Shuang, and Liu clan brothers of the same age. Although he is the smallest, his body is good and his strength is great. He is nicknamed "Pengniuer" by his friends.

Su Bo also liked it very much. So he thought about it secretly and wanted to create a mask that was more useful for Huang Xu.

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

Gongsun is in the middle and protects his mother. Huang Zhong is in front of him and swept away the nightclub. There is also a female assassin who appears from time to time in the backyard. Liu Bei finally slept more comfortably.

After finishing Huang Xu's affairs, Liu Bei then asked Guo Zhi, who was here to discuss in detail.

It turned out that Guo Zhi from Nanyang sent Guo Zhi to exchange for the skills of brewing Jiuyuanchun wine in exchange for the production skills of Lou Sanghemato mats.

What's wrong!

Liu Bei agreed with him. Guo Zhi took out the coupon and Liu Bei looked at it carefully, but there was nothing wrong with it. He signed and stamped it. As the saying goes, there is no basis for speaking. You can think of signing the coupon first when trading, which shows that the Han Dynasty is deeply rooted in people's hearts.

Since the coupon has been signed, how could Guo Zhi hide his own private affairs?

Then I found a good craftsman and followed the map to create wine-making tools.

The design of Jiutan also referred to Guo Zhi's suggestions and made some modifications. However, where did the good water come from?

Go and look for it!

Liu Bei remembered that the reason why Zhuozhou tribute rice became famous in the world in later generations was because it was irrigated with underground sweet springs.

Where does sweet spring come from?

When asked about the third uncle, the third uncle said that there was a thousand-year-old pine tree deep in the wild forest. The ancient trees were towering and vigorous and powerful. There was a clear spring that flowed out from the roots. It was sweet and pleasant, and I forgot the worries when I drank it. Liu Bei was very happy, so he called Guo Zhi and San Uncle, and Huang Zhong went deep into the wild forest. He found the ancient pines and sweet springs.

I saw sweet springs flowing down the tree roots and winding into the clear stream. Guo Zhi said, "It's a waste of resources."

He then asked people to build a thatched cottage under the Panasonic, build a pond to store water, and send it to the winery.

Children of the clan and the newly affiliated people chose their excellent people and learned their skills by learning. Follow Guo Zhi and learn the brewing skills.

Guo Zhi also told the Nanyang clan that he sent people to learn the skills of hemp pads.

Liu Bei also arranged the Guo clan members to study and make mats.

Just as Liu Bei was not worried that the mattress would be imitated. In this era, reputation is sometimes really important. You might as well think of famous people who are half cheaper to buy officials. The bedding that you know the key points had to be opened, but they had to send people to learn with great fanfare. This is called "the teacher is famous."

The wine that I thought was the most difficult, but was the first to build. It was built in front and back yards, with three floors of heavy buildings. It was served in front and back, and brewed wine in the back. It was a shop, elegant seat, and private rooms. The wine sold in the wine was the new specialty of Lou Sang made by the Jiuyuan wine method: Songquan wine.

Before the seedlings of the grass planting, Liu Bei's family had more than 100 acres of seedlings divided into clan members and planted Lou Sang everywhere. From a distance, Lou Sang Village was like a fortress in the water, surrounded by green grass.

This is the most important time of the year. In addition to the normal production of bedding and laying of village lanes, all civil engineering projects have stopped. Liu Bei also drew pictures to let craftsmen create seedlings and horses to assist the clans and the people to plant rice. The seedlings are shaped like a small boat, with their heads and tails raised, and can be used for one person to ride. The operator sits on the back of the boat. If transplanting seedlings, insert the seedlings placed on the bow of the boat into the field with his hands, and then use his feet to make the seedlings gradually move backwards. If pulling seedlings, use both hands to pull up the seedlings, tie them into turns, and place them in the back of the boat. This can not only improve the efficacy, but also reduce labor.

Liu Shaojun, Zhuo County, and the name of Lou Sang Qilinzi, is widely circulated among the people who support them.

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

From a bamboo tube that was originally full of bamboo, it turned into a thin pill of only about an inch. The mask has also been relatively modified. The wooden mask is replaced by a softer and more fitting leather. The filter gasket is supported by thin steel sheets on the front and back. The principle is the same as the hairpin. When you break it back, the steel sheet will be opened by itself, and the gasket can be removed. After changing the new pad, you will break it forward and the steel sheet will be fit by itself, which will stagnate the filter. The entire filter element is designed ingeniously, making it very convenient to disassemble and replace.

The key is that it is easier to breathe after being thinner. If you suffer from long-term illness, Huang Xu will stop wheezing and often forcefully holds her breath. How long hasn’t you breathe so easily?

After the breath was free, I felt that the whole world was different.

The powerful genes accumulated in Huang Xu's body have all awakened one after another. At the age of three, the old patriarch said that it must be a tiger.

Huang Zhong and his wife saw the changes of their only son. The young master Liu Bei was even more serious. Huang Zhong wished he could do his best. He kept walking around the village with his knife all day, full of murderous aura, and even wild dogs dared to approach him.

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

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

At this time, the private armed forces of the powerful landlords have not been made public yet.

After the Yellow Turban Rebellion and the villagers who were suffering from the war, they fled to the families of the powerful families. In order to gather people to protect themselves, the powerful families of the clans, guests, family slaves, disciples, old officials, etc. were compiled into a division. The division became a general term for the private armed forces of the powerful families. It was also called the family army. It was a division in wartime and labor in normal times.

In terms of shooting skills, Huang Zhong was almost invincible at this time and here.

Don’t rush to buy the battle bows. The hunting bows of each company will be fully used after a little transformation.

Liu Bei also became Huang Zhong as his teacher and learned the art of shooting on the battlefield. Previously, the three uncles taught Liu Bei both hunting techniques. Shooting people and beasts was very different. However, Liu Bei had the foundation laid when he was young, so he got started very quickly.

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

Twenty gold is a good horse, and fifty gold is a good horse. One winter passed, and the red horse was fed by Su Shuang for a long time, and it was quite as beautiful as a precious horse.

I saw it, with a high head and a long neck, strong limbs, long mane and neck, and its hair was like a fire. It knocked on the iron hooves from time to time, making it rushing. It was indeed a mixed species of Dayuan horses and Huns. It has good endurance, strong weight carrying, and good at sprinting. Being a ranger and an iron cavalry are both excellent choices.

Huang Zhong loved him deeply and named him Long.
