In ancient China, colors were divided into five primary colors: green, red, yellow, white, and black.

The primary color and intercolor have reached as many as 39 kinds in the Eastern Han Dynasty, and by the beginning of the Tang Dynasty, it has reached more than 40 kinds, such as the primary color of blue, which has derived a variety of intercolors such as egg blue, azure, emerald blue, royal blue, red blue, navy blue, etc.

And these primary colors and intermediate colors, can be extracted from different plants, still take green as an example, can extract the green pigment indigo blue grass has a lot of kinds, in ancient times the initial use of woad, and then gradually found that indigo, horse indigo, wood indigo, amaranth and other kinds can make indigo.

It was the seeds and skewers that Zhu Fengchun provided to Xiang Gong that amounted to more than 300 species, and Xiang Gong couldn't help but smack his tongue.

The main reason is that the color extracted from these plants is slightly different, although it is not obvious, but it can still improve the richness of the color, and each plant is different in terms of cultivation method, growing conditions, length of growth period, where it is taken, and even the method of extraction.

According to this situation, Xiang Gong is afraid that even if he stays in the plantation space all day, he may not be able to take care of it thoroughly, especially in the state of the plantation space to the bonus of crop growth rate, it is even more difficult to take care of everything.

"No, you obviously want to do experiments, if you can't do it, you can just give me those main ones, the ones with a short growth period, all of them are burning your eyebrows, and you still have the heart to extract new colors, it's really ......"

Xiang Gong immediately protested, but he didn't expect Zhu Fengchun to be so concerned about this thing, and took all the categories, isn't it just to find new plant and wood dyeing pigments? Although Xiang Gong wanted to help him, he couldn't get used to him so much.

Listening to Xiang Gong's words, Zhu Fengchun was surprised, "How do you know what experiment I want to do?" ”

"Nonsense, look at the eyes when you introduced me to the current intercolor of more than forty kinds, all of them are so bright, just like watching the little girl strip naked, but you can't touch it, who wouldn't know that you are trying the extraction of new pigments?" Xiang Gong rolled his eyes and said.

"Oh my God, you're so smart, that's what I really thought." Zhu Fengchun was so surprised that he screamed, and slapped Xiang Gong on the back by the way, although Xiang Gong was very useful, but the right thing is the right thing, and it cannot be discounted.

"Hurry up and get down to business!" Xiang Gong urged.

"Alas, in fact, I just tried, I didn't think you could help me, the dead horse should be used as a live horse doctor!" Zhu Fengchun muttered.

Indeed, although Zhu Fengchun has only been in the Gao family for more than three years, with his enthusiasm, he insisted on opening up the original wasteland of the Gao family to plant flowers and plants, and then in a short period of time, he became the leading pigment supplier in Wusi Tibet and even the entire Western Regions.

Just such a problem that a legend in the pigment dyeing industry can't solve, the little-known Xiang Gong can solve it? jokes, Zhu Fengchun really listened to them as jokes.

Xiang Gong could also see that Zhu Fengchun didn't trust him, but it didn't matter, with the wonderful bonus effect of the plantation space, Xiang Gong really didn't think that this thing could be done.

So shrugged and ignored Zhu Fengchun's complaints, Xiang Gong took the last selection of more than 30 kinds of seeds and skewers, said goodbye to Zhu Fengchun, and locked himself in the room.

In view of the experience of Xiao Bailong waiting for a day last time, Xiang Gong first explained to everyone that he was going out in the past few days, so that everyone should not worry, and then specially asked Xiao Bailong not to worry, so that Xiao Bailong was pleasantly surprised.

Subsequently, Xiang Gong pretended to refuse everyone's request to say goodbye and entered the plantation space.

Xiang Gong also came prepared, first took out the dried sweet potatoes in the treasure bag, ready to use them to satisfy hunger, and the selected seeds and skewers are also sustainable varieties, there is no need to re-obtain, plant them once, and wait for the harvest.

In the end, Xiang Gong asked how much Zhu Fengchun's various colors of pigments were still missing, roughly estimated, and temporarily divided into ten days, according to the lack of share of the required land, just like that, Xiang Gong began a ten-day struggle.

Originally, these raw materials are basically flowers and trees, and the growth cycle is much shorter than that of food crops, coupled with the accelerated growth effect of the plantation space, the growth changes of these plants and trees are almost visible to the naked eye.

Except for a short rest after planting the seeds and skewers on the first day, Xiang Gong was not idle for a moment.

The flowers here are blooming, and they are picked in a hurry, and the rhizomes over there are ripe, and they have to break the branches and replant them to collect the stems, and they have to take care of hydration and weeding, Xiang Gong is almost busy as a dog, but fortunately, the effect is also obvious.

Looking at the bags of raw materials, packed with bulging bags and full of Deng, Xiang Gong instantly burst with a sense of accomplishment, without saying a word, he put the collected part in the room, according to the agreement, Zhu Fengchun will take it on time and leave a replacement bag.

However, Xiang Gong soon found out that this was not a way for him, he was too busy, and he had to water, weed, collect, and replant......

In this way, we can't stop for a moment, but we still can't avoid a lot of waste, and the growing period is long and short, and it is inevitable that you will accidentally overlap at the same time to catch up with the harvest period.

Xiang Gong was so busy that he could only watch many petals wither and many rhizomes shrunk, but he could only pant and almost lose the strength to move his fingers, how could this work? Robots are also tired, okay?

When people are always faced with problems, they burst out with potential that they can't imagine, and Xiang Gong's brain may have been fully rested in excess of physical labor, so all kinds of ideas emerge in an endless stream, and the task of the treasure bag also has a place to use.

While harvesting the raw materials of pigments, by the way, he completed the task of the treasure bag and obtained the items he wanted, Xiang Gong was stunned to make a complete set of drip irrigation pipelines with bamboo poles, but unfortunately now the water pump is an overrun appeal, otherwise Xiang Gong can save a lot of effort.

But now Xiang Gong is also very satisfied, the water pump is an overrun item, but the water wheel is not, after completing the task of collecting three thousand wattles, when he saw the water wheel that suddenly appeared in the stream, Xiang Gong felt that the whole world was beautiful.

The wisdom of the ancients is really extraordinary, using the flow of the stream to drive the waterwheel to rotate, and at the same time, the water can be collected little by little into the large water jian (a kind of ancient water container, similar to a water tank) prepared by Xiang Gong.

Da Shui Jian tilted slightly, and when the water was full, it flowed into a bamboo drip irrigation pipe along a bamboo trough that Xiang Gong had made to collect water flow.

When setting up the pipeline, Xiang Gong deliberately took care of the distance between the end of the dropper and Da Shui Jian, and made a gradient rappel on the height, so that he was not afraid that the water in the pipeline would not be drip irrigated due to the consumption of power.

In order to avoid affecting his future farming and collection, Xiang Gong arranged the drip irrigation pipes below his knees as much as possible, and now it seems that this is indeed a wise decision.

As long as the water source continues, drip irrigation will not stop, and there is no need to worry about the lack of water in the field.

After a busy day, Xiang Gong finally got rid of the watering work that greatly affected his work efficiency.

Weeding, Xiang Gong gave up the idea of using drugs, is it green, this is not a joke!

In short, the next day passed in a hurry, and that night, Xiang Gong couldn't help but sleep for a while, but in the Gao family compound, some people couldn't sleep all night.
