Bai Feng, who learned about the latest production and profit of the soap workshop, really felt a lot better.

For the time being, the anxiety caused by Dawei's possible attack on Yamatai was covered up.

Soap workshop has now become the most profitable industry in Bai Feng's hands.

The output of steam engines is limited by steel and craftsmen, and there is only one production line, although the efficiency of the current steam engine production line has been improved three times compared to the beginning, reaching the point of producing three steam engines per day.

However, the profit brought by the sale of steam to Bai Feng is still not as big as that of the soap workshop.

Another very important reason for this is that the nobility in Hanzhong and Yizhou who bought steam engines, after the scale of their steam loom workshops could not be expanded, their willingness to buy steam engines dropped significantly.

Not all nobles had the means to sell steam engines to other states and counties at high prices.

Also, the replacement of steam engines is not so fast.

The second-generation steam engine was first applied to the steam train. It was transformed on the basis of the existing steam engine by craftsmen such as Geng Zhuzi in order to improve the power of the steam train.

Not only can it not be mass-produced, but the cost is also high.

With the profit of the soap workshop as the support, Bai Feng can rest assured that the research and development center and the nitroglycerin and explosives workshop will continue to develop.

Cao Jie has become Bai Feng's logistical support.

If it weren't for Bai Feng's limited energy now, he would also plan to launch more new products.

The incident in Yamatai came to an end, and Bai Feng began to care about the progress of the steam train transformation in the R&D center, as well as the production progress of the nitroglycerin and dynamite workshop.

Bai Feng first came to the R&D center.

Geng Zhuzi, Li Tiedan, Wang Gang, Xu Dali and other craftsmen are nearing the end of the transformation of the steam train.

"Hanzhong Hou, in about four to six days, the renovated steam train can be tested for the second time."

"According to your request this time, the power of the steam train has been strengthened, and there should be little problem in transporting ore and iron ingots in the future."

Geng Zhuzi reported to Bai Feng the progress of transforming the steam train.

Because the steam train will be applied in the mine first, the main direction of this renovation of the farm column is to enhance the power of the steam train, so that the steam train can load more ore and iron ingots.

At the same time, the carriage of the steam train is also in full swing.

Before the first test run of the steam train, Geng Zhuzi and others made a carriage for people, and this time they remanufactured the carriage for transporting ore and iron ingots.

The manufacture of the carriages is progressing rapidly and will be completed when the steam train is commissioned again.

After Bai Feng learned about the transformation of the steam train from Geng Zhuzi, he was ready to start building rails in the mine.

In the current mine, the roads used to transport ore have been refinished and rails can be laid on them at any time.

"Very good, when the second test drive is settled, let me know directly."

Before leaving the R&D center, Bai Feng said to Geng Zhuzi.

Geng Zhuzi nodded immediately, and after Bai Feng left, he devoted himself to the reconstruction of the steam train again.

For Geng Zhuzi, everything about the steam train is a kind of enjoyment, and the transformation process is the same.

Bai Feng left the R&D center and then went to the Nitroglycerin and Dynamite Manufacturing Workshop.

In the workshop, Wei Boyang is leading his disciple Zhen Cheng to complete the improvement of the container for storing nitroglycerin and dynamite.

Zhang Daoyi and Fang Yuan and other alchemists are constantly optimizing the manufacturing process of nitroglycerin and dynamite to reduce the possibility of accidents.

"Mr. Wei, how is the safety improvement of nitroglycerin and dynamite going?"

In the workshop, Bai Feng asked Wei Boyang.

"Reporting back to Hanzhong, regarding the improvement of storage containers for nitroglycerin and dynamite, my disciple Zhen Cheng and I have completed it. Please take a look."

Wei Boyang took out a completely airtight glass container and said to Bai Feng.

After Bai Feng took over the container, he found that it contained yellowish nitroglycerin oil.

"Because nitroglycerin oil itself tends to emit a pungent odor, people will feel dizzy after inhaling too much, so the container must be completely sealed."

"Also, we found during the experiment that the nitroglycerin oil is in danger of explosion whether it is supercooled or overheated, so when transporting the nitroglycerin oil, it is necessary to wrap the glass container with linen. …”

Then Wei Boyang began to introduce their experimental results and safety measures to Bai Feng.

"...It's just that the mixture that can stabilize nitroglycerin oil has not yet been tested, so in the last step of preparing nitroglycerin oil, on-site operations are still required, and there are still certain dangers. ."

Finally, Wei Boyang said to Bai Feng.

After Bai Feng listened to Wei Boyang's introduction, he simply summed it up in his heart.

This nitroglycerin oil does not have a suitable mixture as a stabilizer, so it needs to be configured on-site into an explosive with greater explosive power, so the transportation problem is solved for the most part.

"It seems that the use of nitroglycerin and dynamite will be done by Mr. Wei and other alchemists in the short term."

Bai Feng thought in his heart.

Sure enough, if you want to make the complete body of nitroglycerin and dynamite in a short time, it is not so easy to do even by relying on the formula.

Some of the materials required in the formula are really difficult to manufacture at the current level.

However, the nitroglycerin and dynamite that could be put into use made Bai Feng very satisfied.

As long as you pay attention to safety in the process of using nitroglycerin, there is no major problem.

"Very good, UU reading www.uukanshu.com worked hard, Mr. Wei and Zhen Cheng, this container is very good!"

In the end, Bai Feng said to Wei Boyang and Zhen Cheng, and Zhen Cheng had a big smile on his face when he heard this, looking very happy.

In the process of making nitroglycerin and dynamite, Zhen Cheng felt that it was much more interesting than alchemy, although this process was also much more dangerous than alchemy.

Then Bai Feng and Wei Boyang came to Zhang Daoyi and Fang Yuan who were improving the manufacturing process of nitroglycerin and dynamite.

At this time, the two of them and several other alchemists in the workshop were doing summary records.

After seeing Bai Feng and Wei Boyang coming together, Zhang Daoyi first said to Bai Feng:

"Hanzhong Hou, we have tried our best to make a complete record of all the problems that need attention in the manufacturing process of nitroglycerin."

"And some dangerous operation steps have also been improved and optimized. This is our record, please take a look!"

After Bai Feng took the record book from Zhang Daoyi, he began to read it carefully.
