Bai Feng brought Geng Zhuzi and others back to Hanzhong, Geng Zhuzi also said to Bai Feng:

"Hanzhong Hou, now the first-hand data of the steam train test has been collected, and a lot of improvement work needs to be done in the future..."

"Then you also need to rest for a period of time, and then go to work on the improvement of the steam train. You have plenty of time, and your health is the most important thing!"

After Bai Feng listened to Geng Zhuzi's speech, he interrupted Geng Zhuzi directly.

Li Tiedan, Wang Gang and the others, who originally wanted to explain to Bai Feng that they didn't need a rest together with Geng Zhuzi, immediately swallowed the words they hadn't said yet.

After returning to the city, Bai Feng directly arranged Geng Zhuzi and others to rest in the Hou Mansion.

Before they rested, Bai Feng also personally used spiritual power to recuperate their bodies.

After Bai Feng's spiritual conditioning, the complexion of Geng Zhuzi, Li Tiedan, Wang Gang, and others improved significantly.

The feeling of exhaustion on the body also disappeared a lot.

"Thank you Hanzhong Hou, I'm waiting for He De He Neng..."

The older Wang Gang and Xu Dali were deeply moved by Bai Feng taking care of himself.

This was the first time when they were craftsmen, they were given such attention and courtesy.

Originally thought it was a great blessing to be able to work under Hanzhong Hou's men.

Now the craftsmen such as Wang Gang and Xu Dali all felt in their hearts that even if Bai Feng made them die from exhaustion, they would not have a single complaint.

Bai Feng listened to Wang Gang halfway through, then smiled at Wang Gang:

"Needless to say, you worked so hard for the steam locomotive built for me and the people of Hanzhong."

"I thank you in my heart that it's too late. It's just a trivial matter to help you to recuperate your body."

After Bai Feng's remarks, even Li Tiedan, who was a little insensitive to the world, was deeply moved.

Only under Bai Feng's subordinates and in the R&D center will they feel that all the results of their work are very meaningful and important.

Geng Zhuzi listened to the conversation between Bai Feng and Wang Gang, and in his heart he already thought that Bai Feng had the appearance of an emperor...

Then Bai Feng let Geng Zhuzi and the others rest in peace.

After Bai Feng returned to his room in the evening, Cao Jie smiled at Bai Feng and said:

"Husband, shopkeeper Chen from Yecheng has written a letter today!"

"Oh? If there is any good news in Yecheng, let's hear it."

Bai Feng asked with interest.

Then Cao Jie repeated the contents of the letter from Shopkeeper Chen to Bai Feng.

In Yecheng now, out of the ten soap workshops, five have already started production normally.

The remaining five soap workshops have also been completed.

Shopkeeper Chen is now busy training craftsmen in the soap workshop.

Even the time for drinking with the shopkeeper Zhao of the antique calligraphy and painting shop next door was much less.

The busy life of shopkeeper Chen makes shopkeeper Zhao also very envious.

Recently, shopkeeper Zhao's business has begun to fail again. At this time, shopkeeper Zhao still doesn't know that the battle for the prince of Yecheng is about to come to an end...

"According to the situation described by shopkeeper Chen, in another month, all ten soap workshops in Yecheng can start normally."

"Together with the thirty soap workshops in Hanzhong, we now have forty soap workshops."

"Every year, it's just an income from soap sales. After deducting the dividends for Yecheng's nobles who have invested in shares, there can be about 200,000 taels of silver!"

When it came to two hundred thousand taels of silver, the proud look on Cao Jie's face was already very obvious.

"Hahaha, this is all due to Ji'er. I will reward you for my husband tonight!"

Bai Feng smiled at Cao Jie after hearing the words.

"Well, what are you waiting for?"

Not to be outdone, Cao Jie said to Bai Feng at this time.

Bai Feng was stunned when he heard the words, good guy, are you so brave now? !

After a great harmony of life.

"After the steam train is completed, wait for the nitroglycerin/dynamite workshop to produce nitroglycerin/dynamite, and then you can mine and smelt iron, and the construction of the railway will be put on the agenda."

"Also, the shipbuilding industry in Yamatai needs to be arranged as soon as possible."

"In the future, we will not only need a lot of silver, but also a lot of raw materials..."

Bai Feng hugged Cao Jie gently, feeling Cao Jie's smooth back, and said softly.

Cao Jie quietly listened to his arrangements for future development in Bai Feng's arms.

"Husband, how much change can the steam train bring to Da Wei?"

When Bai Feng mentioned steam locomotives to Cao Jie, he told her that the appearance of steam locomotives was of great significance.

Now Cao Jie finally couldn't help asking Bai Feng.

"Jie'er, what do you think are the factors that restrict the battle of the army?"

Bai Feng did not answer Cao Jie's question immediately after hearing the words, and asked Cao Jie rhetorically.

Although Cao Jie did not understand why Bai Feng mentioned the battle of the army.

But as the wife of the Great Wei God of War, and Bai Feng also likes to tell Cao Jie what he has seen and heard, Cao Jie also has a general understanding of marching and fighting.

"There should be morale, food and grass, and generals. The most important thing should be logistical supplies. Should I remember correctly?"

Cao Jie said to Bai Feng while recalling.

"Well, these are basically these factors. Of course, in actual wars, each of these factors will have a different impact on winning the war."

After listening to Cao Jie's answer, Bai Feng said to her.

Then Bai Feng told Cao Jie about the changes that the steam train would bring to the Great Wei Dynasty through the perspective of war.

"Logistics is the basis for the army to have combat strength. Now it is necessary to transport 10,000 stone grains to the front line of the battlefield hundreds of miles away. During this transportation process, at least half of it will be consumed. food."

"If you encounter bad weather, or complex terrain, or you are at a disadvantage, you will consume more food in logistical supplies."

"But with the steam train, we can transport a large amount of food with almost no loss in the transportation process!"

When Bai Feng said this, Cao Jie already understood what Bai Feng meant.

"That is to say, if the food that could have supported the army for a month was used to supply grain and grass, this batch of grain might support the army for two or even three months?"

"Does this mean that the combat strength of this army can be improved by relying on the supply of steam trains without changing the number of people?"

Then Cao Jie explained his understanding to Bai Feng.

"Jie'er is really smart! That's what it means!"

Hearing this, Bai Feng praised Cao Jie and said that she had learned to draw inferences from one case.
