Chapter 1188 Making Soap

After Bai Feng collected all the drawings, he was ready to go to the R&D center.

Bai Feng, who was about to go out from the study, was seen by Cao Jie.

"My husband, it's almost time for dinner. Are you going out?"

Looking at Bai Feng who was walking hurriedly, Cao Jie asked.

It's almost time for dinner?

Bai Feng didn't expect time to pass so quickly.

"Yes, I just had some new ideas in the study, and I have to go to the R&D center."

"Don't leave me dinner in the evening, I'm staying at the R&D center tonight."

Then Bai Feng said to Cao Jie.

Cao Jie heard it and reminded:

"Well, remember to eat early and rest early when you go to the R&D center!"

"Okay, I know."

After Bai Feng finished speaking, he hurried out to the R&D center.

In the city, Bai Feng bought some raw materials for making soap.

As for the equipment, there are some that Bai Feng can use in the R&D center.

After arriving at the R&D center, Bai Feng found that the craftsmen in the R&D center were not in the factory now.

Geng Zhuzi was not in the factory either.

Bai Feng remembered Cao Jie asking him to eat on time, so he came to the cafeteria of the R&D center.

In the cafeteria of the R&D center, more than 50 craftsmen and students were eating together.

After Bai Feng came over, he found Geng Zhuzi in the crowd.

"Sir?"

Geng Zhuzi said in surprise when he saw Bai Feng.

Bai Feng had just come to the R&D center in the afternoon, so why did he come to the R&D center again in the evening?

Geng Zhuzi was puzzled.

Bai Feng sat next to Geng Zhuzi, and the blacksmith who had been eating with Geng Zhuzi and discussing steam engine manufacturing took the initiative to give up his seat to Bai Feng.

"These two drawings are for you!"

As soon as Bai Feng sat down, he took out two drawings from his arms and handed them to Geng Zhuzi.

Geng Zhuzi took the drawings and saw that one was a mineral distribution map of Hanzhong, and the other was a special steel smelting method.

After reading the two drawings given to him by Bai Feng, Geng Zhuzi's eyes lit up.

"Sir, these two drawings were delivered just in time!"

Recalling the experiment done today, the steam engine parts cast were still relatively brittle.

There were no bubbles inside.

This was a very important breakthrough for Geng Zhuzi and the blacksmiths.

Now Bai Feng has sent Geng Zhuzi a special steel smelting method, which just solved the problem Geng Zhuzi faced next.

There is also the Hanzhong mineral distribution map, which is also very important to Geng Zhuzi.

With the special steel smelting method, plus the Hanzhong mineral distribution map.

He can smelt steel suitable for casting steam engines in a short time.

Seeing Geng Zhuzi's excited face, Bai Feng couldn't help but smile to Geng Zhuzi:

"Now the manufacture of the steam engine should be completed within this month without any major difficulties!"

"No, absolutely not! Please rest assured, sir, the steam engine will be manufactured this month!"

"Hahaha, that's good."

After hearing Geng Zhuzi's very confident answer, Bai Feng also laughed happily.

Then Geng Zhuzi asked Bai Feng:

"Sir, where did you get this special steel smelting method and Hanzhong mineral distribution map?"

Geng Zhuzi held the two drawings as if he had found a treasure, curious about where the drawings came from. He didn't believe that Bai Feng could write them down with his own talent.

Bai Feng was naturally not convenient to explain the source of the two chapters of drawings to Geng Zhuzi, not to mention that the system did not allow Bai Feng to tell the existence of the system.

"Hahaha, you don't have to worry about this, Zhuzi, just make the steam engine as soon as possible!"

"You and the craftsmen in the R&D center will be busy later."

Bai Feng smiled at Geng Zhuzi. The drawings of the train were still in the study of the Hanzhong Marquis' Mansion, and he didn't give them to Geng Zhuzi.

Otherwise, Geng Zhuzi would probably be so excited that he couldn't sleep all night.

It was Bai Feng's idea to let Geng Zhuzi make the steam engine and then give him the manufacturing drawings of the steam train.

After handing the two drawings to Geng Zhuzi, Bai Feng ate something in the canteen of the R&D center to fill his stomach.

Then Bai Feng took the various raw materials for making soap that he had prepared and returned to the factory of the R&D center.

After dinner, the craftsmen were ready to rest.

Geng Zhuzi was carefully studying the special steel smelting method.

So now in the R&D center, no one else came to disturb Bai Feng from making soap.

"It's a pity that there are no generators and electric lights now."

The sun has completely set now.

In addition, there is no glass in the windows of the entire R&D center, so the factory of the R&D center is dark.

After Bai Feng lit a candle, he began to make soap.

"Animal fats, spices, heating, boiling"

According to the method on the drawing, Bai Feng started the first soap making.

Two hours later, Bai Feng completed the making of the first soap.

Because the essential oil has not been made by Bai Feng yet, Bai Feng uses cloves as the source of fragrance for this first soap.

Put the whole soap under your nose and smell it, and the fragrance of cloves fills Bai Feng's entire nasal cavity.

"Well, not bad!"

Now that Bai Feng is satisfied with the scent and appearance of the soap, all that's left is to test the cleaning effect of this soap.

In Bai Feng's opinion, the cleaning effect of this soap should not be comparable to that of later soaps.

But it will definitely have a much better cleaning effect than the current plant ash, soap locust and bath beans.

Bai Feng brought a basin of water and then randomly found a rag in the factory.

Bai Feng put the dark rag in the basin and soaked it, then applied soap on it. Bai Feng began to clean the rag.

After washing it three times, Bai Feng smiled with satisfaction when he saw that the rag was obviously much cleaner in the candlelight and also had some clove scent.

"The effect is really good. The fragrance remaining on the rag is not much different from the original soap."

Bai Feng said softly.

This soap making was a complete success!

Bai Feng then put away all the tools and raw materials used to make soap, and then left the R&D center factory.

At this time, the moon was already high in the sky.

"Well, at this time, the plowing column in the dormitory of the R&D center should have gone to bed. It seems that I will have to sleep in the Marquis Mansion tonight."

Bai Feng then remembered that he had forgotten to ask Geng Zhuzi to prepare a dormitory for him. Now it was too late and Bai Feng didn't want to disturb Geng Zhuzi's rest.
