Cao Cao immediately drafted an edict to start building cement straights across the country after the spring plowing was completely completed.

After writing the edict, Cao Cao suddenly discovered a new problem!

"Mr. Lin, the whole country has started to build cement straights, I wonder if this cement can be enough?"

Cao Cao, who thought of this, asked Lin Chuan.

"King Wei, relying only on the cement produced in Hanzhong and Xuchang is naturally far from enough."

Lin Chuan also directly answered Cao Cao's question.

"Does Mr. Lin have a solution?"

"Of course there is, but like building a concrete straight, the effect is not immediate."

Lin Chuan gave Cao Cao a preventive shot in advance this time.

Without waiting for Cao Cao to ask again, Lin Chuan immediately said:

"The Hanzhong Chamber of Commerce can help the prime minister solve this problem!"

Cao Cao came to the spirit again this time, he didn't expect the Hanzhong Chamber of Commerce to develop so rapidly, and now it can affect the whole country?

"Mr. Lin, this king knows that the Hanzhong Chamber of Commerce has now built branches in important towns in various states and counties, but with so much cement, sand and gravel need to be transported, how can a state and a county be successful with only a few branches?"

Cao Cao did not hide the doubts in his heart.

Lin Chuan told Cao Cao about his latest plan for the Hanzhong Chamber of Commerce.

"King Wei, don't be impatient, I'll talk to you in detail."

"Okay, Mr. Lin, please speak!"

So Lin Chuan continued:

"King Wei, the thirteen states and nearly 100 counties under the jurisdiction of this world, the Hanzhong Chamber of Commerce branches in these places will be completed before the autumn harvest next year."

"After that, plus the time it takes to recruit people, these clubs will be up and running before the Chinese New Year!"

Hearing this, Cao Cao couldn't help but nodded, he knew that it was very fast to build a house with red brick cement.

"And the nine production bases in Hanzhong are now in full swing!"

"Nine production bases?!"

Cao Cao's eyes widened in surprise.

In addition to the secret workshop in Xuchang that has been expanded after the Battle of Chibi, the production base in Yecheng is still under construction.

So Cao Cao couldn't understand why Lin Chuan's production base could expand so quickly!

At this moment, the door of the side hall was pushed open, and Xun Yu walked in.

Xun Yu was in Xuchang before to deal with the mobilization of grain and grass for disaster relief, and at this time, he had just rushed back from Xuchang, so he came directly to the Wei Palace to report to Cao Cao.

Seeing Lin Chuan, who was discussing with Cao Cao, Xun Yu was also quite surprised.

"The Marquis of Hanzhong is also there?"

"Wen Ruo has worked hard all the way, first sit down and drink some tea and rest."

Cao Cao first said to Xun Yu, and then talked about Lin Chuan:

"Mr. Lin only arrived in Yecheng yesterday, and now this king is talking to Mr. Lin about disaster relief."

Xun Yu was in Xuchang to deal with disaster relief affairs, and when he heard Cao Cao say that he and Lin Chuan were talking about disaster relief, he did not directly take out the disaster relief records in his arms, but planned to listen to what Lin Chuan could do.

Cao Cao briefly mentioned to Xun Yu that Lin Chuan attached great importance to cement straights, and that he was ready to carry out a national plan to build cement straights.

After hearing this, Xun Yu said to Lin Chuan:

"The Marquis of Hanzhong is far-sighted and points to the root of the problem!"

Lin Chuan smiled and waved his hand:

"I'm just making suggestions, if you want to talk about the big and small things of disaster relief, you still have to be able to arrange it clearly by Mr. Xun."

After exchanging polite words, Lin Chuan continued with the question that Cao Cao had just discussed:

"In today's Hanzhong production base, all products have been produced by assembly lines."

It was the first time Xun Yu had heard the word assembly line, so Lin Chuan briefly explained to Xun Yu again.

Xun Yu, who figured out what assembly line production was, had a new understanding of Lin Chuan's talent.

"And the parts produced by each assembly line all have a unified standard, and the people only need to learn to make one part."

"So in the Hanzhong production base, as long as the people have a little training, they can directly produce!"

"Now there are nine production bases, which can produce tens of thousands of parts and assemble thousands of products every day!"

Speaking of this, Lin Chuan also took out two copies of the recruitment notice that was printed at the beginning from his arms.

After handing the notice to Cao Cao and Xun Yu respectively, Lin Chuan had the opportunity to take a sip of tea and moisten his dry throat.

Cao Cao and Xun Yu read Lin Chuan's recruitment notice, and they were both very emotional.

"Mr. Lin, according to what is written in this notice, isn't it true that most of the people in the entire Hanzhong can enter this production base to work?"

Cao Cao couldn't help but ask.

"Yes, it is indeed as King Wei said!"

"No wonder Hanzhong can build nine production bases at the same time in a short period of time!"

At this time, Cao Cao finally understood the secret of the rapid expansion of the Hanzhong base, that is, the assembly line operation!

However, in order to build a production base on a large scale in a short period of time, it is necessary to have enough craftsmen as masters to train the people who enter the production base to work.

And everyone also believes that working in the production base can really live a better life than farming!

Cao Cao could only sigh that Lin Chuan's preparations were very sufficient, and it was impossible to replicate Hanzhong's practices in Xuchang and Yecheng.

Then Cao Cao put the notice on the table.

In addition to understanding the reason for the rapid expansion of the Hanzhong production base, Xun Yu also keenly found that the notice on the table was exactly the same as the one in his hand!

Whether it's handwriting or anything else, it's exactly the same!

Lin Chuan originally planned to give the two notices to Cao Cao together, so that Cao Cao could find that the two notices printed by movable type printing were the same.

And Lin Chuan planned to use movable type printing as a surprise gift to Cao Cao when he came to Yecheng.

After Lin Chuan saw that Xun Yu had discovered the secret of the two notices, he did not directly tell the movable type printing.

"I wonder how the Marquis of Hanzhong wrote these two notices so similarly?"

Xun Yu couldn't help but ask the doubts in his heart.

After Cao Cao heard Xun Yu's inquiry, he also took these two notices in his hand at the same time for observation.

After a closer look, Cao Cao also found that the two notices were exactly the same!

"Mr. Xun has good eyesight!"

"These two notices were printed by movable type printing!"

"Movable type printing?!"

After Cao Cao and Xun Yu heard Lin Chuan's answer, they both exclaimed, what kind of novel invention is this Lin Chuan?

So Lin Chuan popularized what is called movable type printing for Cao Cao and Xun Yu.

"Mr. Lin, this movable type printing technology can be described as a major invention for the benefit of the country and the people!"

"Hanzhong Hou, this is a convenient door for the world's scholars!"

Both Cao Cao and Xun Yu instantly understood the importance of movable type printing.

"The movable type used in movable type printing has been mass-produced in the Hanzhong production base."

"I also brought some to Yecheng this time as a gift for King Wei!"

After Lin Chuan finished speaking to Cao Cao, he heard Cao Cao's hearty laughter:

"Hahaha, this king has Mr. Lin, the Hanzhong Chamber of Commerce, what are you afraid of natural disasters!"
