Building roads and bridges. Although tools are still in the Stone Age, the courage of infrastructure construction is already hidden in the bones.

There is definitely not enough population, tools, and grain. At present, there is definitely not enough food, and the tools are not good enough, so the population can only be used to make up for the shortcomings of both. Therefore, the major projects in Lu will be carried out through a large amount of corvee, because they all bring their own food, and the construction period can be reduced, so the food consumed by each person will be reduced.

Five hundred people spent three months to build roads, which was a normal level in Lu.

With a bridge, the carriage can pass through easily. It might have taken half a day to cross the river, but now it only takes a few breaths to pass through the flat wooden bridge, and there is no need to worry about how heavy the car is installed.

As more people come to the fief, the handicrafts prepared by the wild people themselves can also be exchanged for more feed, or for resources that are not available in the fief.

For example, salt. Although Yunyao does not lack salt, the wild people lack it. After becoming rich, they also want to eat salt every meal.

There are also better leathers. Change all the clothes and quilts in the house that are spliced ​​with different furs to replace them with better looking ones. When you are full, you must start pursuing aesthetics.

As the lord of the fief, Yunyao deeply felt that the residents in the fief were chasing him, and maybe one day the living conditions of the savage would surpass her.

Now Yunyao is working hard to manage the medicine garden and strive to get the medicine well. He needs to water it at a specific time. He must know how to look at the astrological signs and count Feng Shui. In short, it is not only necessary to grow fairy medicines, such as how much watering, how much sun exposure, what fertilizer to apply, and how much fertilizer to apply. These are very important for ordinary crops, but fairy medicines do not only require these, but also need to meet some unquantifiable conditions. They can only be satisfied by measuring the time and looking at Feng Shui.

It was also the first time that Yunyao grew elixirs and strictly followed the "Farmer's Techniques". Ganoderma lucidum and ginseng have emerged in more than 20 days and are growing well.

"In this way, it will take about ten years of medicine to grow in a year to meet the initial needs." Yun Yao still wants to challenge the planting of a hundred years of medicine to grow in a year.

The amount of medicine that can be grown depends on the level of the medicine garden. The medicine garden that Qingfeng Yiqiu has cultivated is the most basic, just like the seven-star array of Hongsang. It is already the upper limit to grow the medicine power of ten years within a year. But Yun Yao has a plug-in, and she has to use her annual rings to challenge her to grow the medicine power of a hundred years within a year.

At first, she pulled the seedlings to help grow and wanted to succeed in one breath, but the seedlings exploded directly, making her realize that the elixir is very delicate and should be careful not to be too rough. So she changed the method, which was to use annual rings every day. She also divided the experimental subjects such as A, B, C, D and Wu. The time of exposure is different every day. We need to see what the difference is the elixir illuminated in different time periods after maturity.

This is also accumulating experience, and it is like astronomy journalists who have been recording the starry sky and weather for many years, and to draw the trajectory of the starry sky, and to obtain different solar terms in a year.

Because it has been common sense to draw conclusions after years of recording and then passed on from generation to generation.

What Yunyao has to do now is also a record. She suspected that the immortal could skip this process and get a conclusion directly, because the immortal could calculate, but unfortunately she was not an immortal yet, so she could only use this stupid method.

The result was much better than Yun Yao thought. After three months, the road was completed, the green light elixir in the medicine garden had grown, and half of the elixirs illuminated by the green light had a hundred years of medicinal power, while those who did not meet the requirements also had fifty or sixty years of medicinal power.

"The irradiation at night is over a hundred years old, which means that the effect of green light at night is better than that during the day?" Through experiments, Yun Yao discovered this pattern, and the power of green light was halved during the day.

"It has achieved a year's effect in three months, and the speed is very fast. These trees can have a good harvest." Yunyao did not continue to shine because she knew that it would be impossible to continue to provide nutrition when she continued to illuminate the medicine garden. The century-old medicinal power is the limit of the primary medicine garden's green light.

First put the mature herbs in the jade box, continue to cultivate the others, and record the results of different medicinal materials being exposed to green light at different growth stages. See if it is better to illuminate during the seedling period, or to illuminate during the growth period, or to illuminate after growth.

Today, Yunyao left the medicine garden because he was about to start weaving golden silk.

After debugging and multiple uses, the use method and ability of the jacquard machine have been discovered. Yun Yao thinks that it should be able to put on golden silk.

So I chose a day with a clear and refreshing autumn and entered the thatched cottage to start weaving.

"I tried it with ordinary silk before and hemp rope. There was no problem with the loom." Yunyao entered the house and was about to start construction.

Prepare to go online first. This is a very troublesome preparation process. Because the warp rake that needs to be removed is sorted out, grinding a crochet with bamboo pieces, and reaching the thread through the wire eye on the warp rake can save a lot of time. There are few warp threads and more weft threads, ten parts of silk, four parts of warp threads, and six parts of weft threads.

Then put the warp rake back into the jacquard machine and fix the warp thread.

Then prepare the spindle and shuttle, use hands and feet together, and start work.

As Yunyao stepped on the pedal, the warp lines separated, and swung the shuttle with his right hand through the gap, then pulled the warp rake with his left hand to tighten the weft line, and then stepped on the pedal warp lines to exchange the gap again, and swung the shuttle with his left hand back to his right hand...

The huge jacquard machine started the repeated work.

The golden silk gradually formed, which was normal at the beginning. Although it was much heavier than ordinary silk, Yunyao didn't think there was any problem with some brute force. However, as the silk became longer and longer, Yunyao found that the golden silk was actually absorbing her mana. Moreover, the movements of the jacquard machine became heavier, and Yunyao needed to do her best every time.

This is so abnormal, why is this happening?

No one can answer it, because no mortal has ever processed gold silk with a jacquard machine in the mortal world, let alone Yun Yao specially expanded the loom for processing.

In the past, there was gold silk but no loom. In the Shang Dynasty, there was a loom but no one had processed gold silk. Now Yunyao uses a unique way to process gold silk, which is definitely the first time in the history of the prehistoric world.

Since it is an unprecedented attempt, anything is possible.

So heavy and so tired, Yunyao sweats heavily but can't stop because she feels that her body is dominated by the power of heaven and earth. Now she is a medium, and what she is really weaving is the ubiquitous power. However, this power is too huge. Du Niang, as a medium, is under pressure that exceeds her body's limits every moment.

Every movement is like letting the cells stretch, and the cells are constantly being pulled like rubber bands. Only the person involved knows the feeling.

Fortunately, Yun Yao usually blesses the weight of the power of heaven and earth for physical exercise, otherwise she would have been unable to withstand the split.

Hongsang noticed that there was a stream of energy condensing in the fief, and thought that someone was experiencing a tribulation nearby. After sensing, he found that his good apprentice had become a part of a jacquard machine and could not restore freedom.

I hurried to Yunyao and saw that the golden silk was filled with incredible energy. The clouds emitted red light of the sunset, and the lightning pattern released the golden light...
