After many chemical reactions, a little white transparent crystal was finally extracted. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Ling Motang touched those white and transparent crystals and was deeply pleased: the production method is right, and now the canteen can be handed over.

Limited to small tools, so caustic soda can not be made in large quantities, can only be repeatedly refined on a small scale, and when the moon is full in the west building, she will gather three porcelain bottles of caustic soda.

"Ling Motang, I brought you the glycerin you wanted." Tang Chuxue came in with Su Zhuohua, which made Ling Motang a little surprised, these two people could still go in and out together without fighting, which really surprised her.

"What are you looking at?" Su Zhuohua found Ling Motang's gaze on her, and sneered: "Compared to you, Senior Sister Chu Xue doesn't have as many fancy intestines as you, and it's difficult to deal with." ”

Ling Motang shrugged his shoulders and took the glycerin from Tang Chuxue's hand: "You came just in time, let me show you the birth of the world's first sulfur soap." ”

The process of making sulfur soap is actually very simple, as long as the glycerin and caustic soda solution are mixed at high temperature, the soap is formed, and an appropriate amount of sulfur is added to the liquid soap, and sulfur soap can be produced when the liquid solidifies.

Tang Chuxue and Su Zhuohua were extremely interested in novelty things, staring at Ling Motang's every move.

"Borrow a fire." Ling Motang winked at Su Zhuohua, Su Zhuohua was a fire attribute and his proficiency in using fire was much better than Ling Motang's.

Under Ling Motang's guidance, Su Zhuohua saw that the caustic soda and oil in the porcelain bottle had a chemical reaction, and the white crystals in it mixed and melted with the oil to form a thick and greasy liquid.

Ling Motang stirred with a porcelain tube, and finally put the large porcelain bottle in a wooden basin filled with water to cool, after an hour, the liquid in the wide-mouth porcelain bottle solidified, Ling Motang knocked out the solid in the porcelain bottle, cut it on the soap body with a dagger, divided the irregular large soap body into regular sulfur soap, and finally carried out decorative polishing.

"It's amazing." Tang Chuxue picked up a palm-sized piece of sulfur soap and looked at it, and then approached and sniffed: "There is no sulfur choking, it is slippery and greasy, you said that the cleaning function of this sulfur soap is very good?" ”

"You can try." Ling Motang threw a dirty handkerchief into the water, Tang Chuxue used sulfur soap to scrub the handkerchief several times, and then washed it in clean water, and the stained handkerchief returned to its original cleanness.

"It works so well." Su Zhuohua also squatted down and looked at the white handkerchief in Tang Chuxue's hand, turned around and asked Ling Motang, "How much does it cost to make this sulfur soap?" ”

Ling Motang smiled like a profiteer: "Such a large jar of sulfur only costs ten yuan, and the production of a can of caustic soda only needs fifteen yuan, plus sixteen yuan of glycerin, but the raw materials of this jar can make no less than twenty yuan of sulfur soap, what do you say is the cost of a piece of sulfur soap?" ”

"Oh, Hua Gu's Fenghuafang sells ten taels of cleaning supplies, and it is not convenient to have a long effect, but this sulfur soap works quickly and has a low cost, so it is very profitable." Su Zhuohua got up, the smile in his eyes was very genuine, and he seemed to be happier than Ling Motang.

"If it's limited to Fenghuafang, won't it be a loss?" Ling Motang blinked: "Good things naturally want to make him famous all over the world." ”

"You mean, selling it down the hill?" Su Zhuohua immediately understood: "That's fine, but you're not an inner disciple yet, I'm afraid you won't be able to go out of the Cloud Sect." ”

Ling Motang dragged Tang Chuxue, who was still studying sulfur soap, from the ground and pulled a girl with one hand: "Come here." ”

Su Zhuohua and Tang Chuxue followed Ling Motang to the courtyard, Ling Motang mobilized the aura in her body, pinched her fingers, and the green light floated around her, she led the aura to the dead tree, and in an instant, the dead tree sprouted, and it was she who used the wood attribute to urge the rebirth of the tree.

"Can you transport the aura?" Tang Chuxue shouted.

"Three layers of Qi training." Su Zhuohua smiled on his lips: "When I came, I found that there was a faint aura flowing on your body, but you once told me that you couldn't transport the aura, so I didn't ask you about it, did you suddenly practice aura last night, and you entered the third layer of qi cultivation all of a sudden." ”

"Yes, I once gathered spiritual energy in my body, but I couldn't transport it out, but last night's few copies of "Spiritual Luck" solved my dilemma, and I found a method suitable for my own cultivation, and the spiritual energy that had been gathered in my body entered the stage of qi cultivation after it was transported out." Ling Motang smiled lightly, she just released a little aura, creating the illusion that she had already practiced low-level aura, if she told Su Zhuohua and Tang Chuxue that she had broken through the ninth layer in one night and she could use the spiritual power of the five attributes, then it would not make these two people drop their jaws?

Therefore, Ling Motang decided to keep quiet for the time being, and use his spiritual power proficiently before the inner gate competition, and strive to win the qualification to enter the inner gate.

"However, the wood attribute is the most useless of all the attributes, and you are only practicing the third layer of qi, I'm afraid it will not be easy to enter the inner door." Su Zhuohua frowned: "I have a few pills, I will give them to you when you go to my place at night, you strive to enter the eighth layer of qi cultivation before the competition, and the eighth layer can only compete with the spiritual power of other fifth-layer attributes for the wood attribute." ”

"Don't worry, I am bound to win this inner door test, if I don't get the qualification to enter the inner door, how can my ambitions be realized in the future." Ling Motang was in high spirits, Tang Chuxue was sincerely happy for Ling Motang, and took Ling Motang's hand and jumped up: "Motang, I knew that you were so smart, you would definitely be able to practice Qi Sense, it's just a matter of time, it's great that you can break through the third layer overnight, and you will definitely be able to reach the eighth layer of Qi cultivation in the next two months." ”

Su Zhuohua also nodded to Ling Motang in affirmation: "I'm waiting for you to show your ambitions." ”

"Do you want to invest in my research first?" Ling Motang raised her eyebrows, the silver tickets that she originally planned to buy the shop were all taken away by Shen Yuan, and she had already spent all her savings to buy raw materials, and now she was penniless.

Su Zhuohua chuckled: "This is natural." Originally, I thought you were just talking, but I didn't expect that the sulfur soap you invented was really profitable, so I can contribute a part of the raw material investment of sulfur soap next, but we have to share the profit of the silver. ”

"Cheng, since the three of us are in the same boat, then I won't make a lot of money, you are thirty percent, the first snow is thirty percent, I have technical input, so I forty percent, no opinion." Ling Motang's peach blossom eyes were full of smiles: "I'm mean enough." ”

"Deal." Tang Chuxue and Su Zhuohua spoke in unison, and the three of them high-fived each other, and then looked at each other and smiled, full of tacit understanding.

"Now, it's time for me to take the cash cow of Hua Gu." Ling Motang stretched his waist, and he could finally get a good night's sleep tonight.
