Xie Songlin counted the cakes to be shipped tomorrow. The number was not large at the moment. Qiuyue and Qiuye were always efficient and skilled in making cakes. It wouldn't take long for them to complete tomorrow's order.

At daybreak, Lin Jian and his friends came to pick up the cake. Xie Songlin had explained yesterday that the cake was soft and couldn't be held in their hands. Besides being inconvenient, if they accidentally pinched it, the cake's shape would be ruined, and its appearance would affect sales.

Everyone remembered what was said, and when they came, everyone brought a bamboo basket, which was enough to hold two or three cakes. Lin Jian wanted more, so he carried a small backpack.

By this time, Xie Songlin had already divided the cakes according to the number registered yesterday. Each cake was carefully wrapped in a layer of wax paper. The wax paper was a light yellow, tightly wrapped around the cake. This way, even if there were some bumps on the road or if it was accidentally rubbed, the cake would not be dirty.

Xie Songlin stood in the yard, an expectant smile on his face as he said to the people preparing to set off, "I wish you all success!"

"it is good!"

Xie Songbai and his friends also packed some cakes into bamboo baskets, and the three brothers drove an ox cart to the town.

Xie Wanxing finished her breakfast leisurely and walked into the yard. The yard seemed particularly quiet at this time. Before, whenever she disappeared for a while, Xie Lan and others would look for her and catch her, preventing her from running around outside.

Now, Xie Lan and the others have gone to the old ancestral hall, leaving only Aunt Li busy with housework in the house. Even the sisters Qiuyue and Qiuye have gone to the ancestral hall to attend classes. Cheng Hui is busy taking care of Xie Yao. Although Xie Ning is at home, he always lies alone on the tree outside and doesn't come to take care of her affairs.

What makes Xie Wanxing even happier is that most of the house has been renovated. It won’t be long before she will have her own independent room. When the time comes, she can do whatever she wants by closing the door.

In short, it will be much more convenient for her to enter the free space to study other things in the future.

Xie Songlin also had breakfast. Seeing Xie Wanxing happily spinning in circles in the yard, he coughed lightly. The father and daughter looked at each other silently, and then walked out of the yard together in tacit understanding.

As Xie Wanxing walked, he shouted towards the house: "Mom, Dad and I are going to the back mountain for a walk!"

As usual, Xie Ning was lying on a big tree outside the yard, in a lazy posture, holding a steamed bun casually in one hand. The bun was still steaming, obviously it had just been taken out of the pot. On his other hand was hanging a cloth bag, which was bulging and filled with steamed buns that Aunt Li had steamed for him.

He half-closed his eyes and just saw the backs of Xie Songlin and Xie Wanxing leaving stealthily. He raised his eyebrows, then slowly took a bite of the steamed bun in his hand. After chewing it for a few times, he turned his head to look elsewhere, slowly closed his eyes, and continued to chew the steamed bun in his mouth slowly, as if everything around him had nothing to do with him.

Xie Wanxing and Xie Songlin found a secluded place and entered the space. As soon as they entered the space, Xie Wanxing couldn't wait to urge: "Dad, hurry up, hurry up, do it."

Xie Wanxing and Xie Songlin had accidentally discovered before that there were some Eucommia trees growing scattered on the mountain behind the village. Every time they said they wanted to go up the mountain for a stroll, they didn't really mean to wander around aimlessly.

Every time they went up the mountain, they were busy collecting the bark, leaves and fruits of the Eucommia trees. After "strolling" up the mountain again and again, they really collected quite a lot and then hid them all safely in the space. Not only that, they also transplanted some on the black soil, waiting to grow more high-quality Eucommia trees.

Eucommia ulmoides, also known as rubber wood.

Xie Wanxing had looked up some information before and had a general understanding of how to use Eucommia gum. Currently, the most suitable method for them is boiling in water.

First, wash all the collected materials clean, then put them into water and boil them. During the boiling process, the eucommia gum will slowly dissolve into the water.

After the water has been boiled for a while, the cooking liquid in the pot has been fully mixed with the dissolved Eucommia gum, but it is also mixed with some residues that have not been completely dissolved, such as some fine bark chips, fibers, etc. At this time, you need to use finer gauze to filter the cooking liquid, leaving all the residues on the gauze and allowing only pure cooking liquid to pass through. In this way, you will get a solution that initially contains Eucommia gum.

When the solution cools down, the Eucommia gum will gradually solidify and precipitate during the cooling process.

However, the purity of the Eucommia gum extracted for the first time is definitely not enough. In order to improve the purity and quality of Eucommia gum, it needs to be further refined.

Put the collected Eucommia gum into clean water again, stir gently to allow the impurities to dissolve in the water as much as possible, then pour out the water. Repeat this process several times to remove some of the impurities and obtain some Eucommia gum of better quality.

Xie Wanxing, a master of theoretical school, wrote a whole page about the extraction method. Today she plans to try it herself. If it works, the conveyor belt of the harvester will have a clear idea. Moreover, this eucommia gum can replace rubber, so there are many things that can be made from it.

Xie Songlin took the piece of paper with the Eucommia gum extraction method written on it that Xie Wanxing handed over and quickly scanned it. The steps were detailed and looked quite reliable.

Xie Songlin had built a stove in the field outside before. Since they had figured out everything, the father and daughter didn't delay and rolled up their sleeves to start working. They washed the chopped pieces of Eucommia bark and leaves with spiritual spring water, threw them into the big pot and started to cook.

As the water rolled, the eucommia gum slowly dissolved into the water, and the originally clear water gradually turned into a brown solution.

Xie Songlin stood aside, his arms folded across his chest, staring intently at the increasingly thick brown solution in the pot. He stirred it with a spoon and said, "Dr. Xie, the master of theory, has something on his plate!"

Xie Songlin and Xie Wanxing followed the recipe written by Xie Wanxing, proceeding step by step in an orderly manner. After a while, they really cooked a pot full of rich-colored Eucommia gum solution.

But it's almost time for lunch now, and they both have to go home for lunch. It's a good opportunity to put the solution here to cool down, and wait until they go out for a "stroll" in the afternoon to come back and see if the Eucommia gum can be used.

Xie Songlin dragged Xie Wanxing back home. Before they reached the door, they saw a group of people gathered at the door from a distance, making a lot of noise.
