Jiang Wei was excited about Great Wei's preparations for overseas expansion, and it took a long time before he fell asleep.

At noon the next day, Jiang Wei, Cao Chong and Deng Ai all came to Lin Chuan's study.

"The teacher called you over this time to talk to you about the changes and adjustments that the Hanzhong Chamber of Commerce will make after the maritime trade in the Great Wei."

After the development of maritime trade, Lin Chuan was able to take out the drawings that could not be directly produced and manufactured in the system lottery and handed them over to the R&D center for development.

The reason for this includes not only the shortage of raw materials for production, but also the shortage of manpower in the production base.

If you want to produce a commodity on a large scale, one is inseparable from manpower, the second is inseparable from the production of raw materials, and the third is inseparable from technology.

Now because of the existence of the system, Lin Chuan has the most important thing in his hands is technology, but whether it is the manpower for the mining of raw materials for production, or the manpower for processing and manufacturing, there is a relatively short of manpower.

Because Dawei is based on agriculture, Lin Chuan must increase the output of the production base as much as possible without affecting agricultural production.

After the development of maritime trade, the production of raw materials that are relatively restricted to the Hanzhong Chamber of Commerce will be greatly supplemented.

"After the Great Wei began maritime trade, the Hanzhong Chamber of Commerce will usher in a major change."

After Lin Chuan finished speaking, he put the three drawings in front of Jiang Wei, Deng Ai and Cao Chong.

"Steam engines, trains, naval guns?"

Jiang Wei looked at the three drawings that Lin Chuan showed them, and softly read out the names of the items each of the three drawings represented.

"Teacher, what are these three items used for?"

Cao Chong asked Lin Chuan puzzled.

"The steam engine can be simply understood as the power obtained by boiling water.

Trains are cars powered by steam engines that do not need to be pulled by horses to move forward.

As for the naval cannon, it is an improved version of the Kamui cannon, and it is suitable for the Kamui cannon to be used on the treasure ship! ”

Lin Chuan briefly explained the situation of these three new inventions to Jiang Wei, Deng Ai and Cao Chong.

"Old, old, teacher, a car that can run without relying on horses, why is that?"

Deng Ai was more interested in the train, so he asked Lin Chuan.

So Lin Chuan explained to Deng Ai in more detail how the train works.

"It turns out that trains need special 'railways' and steam engines to run, which is really amazing!"

After listening to Lin Chuan's explanation, Jiang Wei said excitedly.

"Hahaha, these steam engines and trains can only be produced in large quantities after the maritime trade has begun.

However, naval artillery can be developed now. ”

Lin Chuan smiled and continued to Jiang Wei and the others.

As a result, Jiang Wei, Deng Ai and Cao Chong looked forward to the upcoming maritime trade.

Lin Chuan let Jiang Wei, Deng Ai and Cao Chong see the drawings and explain to them, and then continued to tell the three about the changes that the Hanzhong Chamber of Commerce and Great Wei would face next.

"After the start of maritime trade, with the various commodities of the Hanzhong Chamber of Commerce, we can trade all over the world and obtain all kinds of materials needed by the Hanzhong Chamber of Commerce and the Great Wei.

For example, steel, coal, rubber, gold and silver and other minerals.

With these resources as raw materials for production, the Hanzhong Chamber of Commerce can carry out the research and development and production of steam engines and trains.

In addition, it can be used to produce more tools for the people of Dawei to use. ”

Lin Chuan said this, Jiang Wei, Deng Ai and Cao Chong were already a little unable to keep up with Lin Chuan's train of thought.

However, the three of them did not interrupt Lin Chuan's narration, and Lin Chuan continued to say to the three: "At that time, the Great Wei will not only become the center of the whole world, but the lives of the people of the Great Wei will also undergo even greater changes.

This change is certainly going to get better.

However, we also need to be prepared for this change in advance.

Therefore, this time the division was preparing to go to Yecheng, precisely for the upcoming maritime trade, to explain the benefits and disadvantages to the King of Wei, so that the Great Wei court could prepare early. ”

At the end of speaking, Lin Chuan's tone changed from the previous brisk tone to a lot more serious.

"Teacher, after the development of maritime trade, there are many benefits to Great Wei, but how did this harm come about?"

Cao Chong couldn't help but ask Lin Chuan.

"Cangshu, you said, the construction of Hanzhong Vocational Training College has obvious benefits to Dawei, but at the beginning, why did the scholars in Yizhou unanimously oppose the construction of Hanzhong Vocational Training College in Yizhou?"

Lin Chuan did not directly answer Cao Chong's question, but asked Cao Chong rhetorically.

Cao Chong heard his teacher Lin Chuan mention the construction of Hanzhong Vocational Training College in Yizhou, and he understood why Lin Chuan explained the benefits and disadvantages to his father Cao Cao, and made preparations early.

Jiang Wei and Deng Ai also understood what their teacher Lin Chuan meant to them.

The Hanzhong Chamber of Commerce will be able to make greater profits from maritime trade, and the production base will be able to upgrade its production capacity.

In this way, every Hanzhong branch, every production base, and every student about to graduate from Hanzhong Vocational Training College will become more valuable.

The officials of the Great Wei clan, in the face of such huge interests, how many people can be indifferent?

Therefore, it is very important for Lin Chuan to let the Hanzhong Chamber of Commerce continue to develop normally after the development of maritime trade, and to get the full support of Cao Cao and the Great Wei court.

Lin Chuan saw that Jiang Wei, Deng Ai, and Cao Chong all understood what he wanted to express, so he stopped explaining Cao Chong's questions.

"The construction of the Hanzhong Vocational Training College, the renovation of water conservancy facilities, and the upcoming construction of Hanzhong branches and production bases at various ports in Yangzhou are all preparations for the Hanzhong Chamber of Commerce to meet the maritime trade.

We have to be one step ahead to better cope with the changes that come next. ”

Jiang Wei, Deng Ai and Cao Chong also experienced a trace of unusual feelings at this time.

They felt that Da Wei was about to undergo another great change, but the three of them were more expecting the arrival of this change than worrying.

Because they believe that with the presence of teacher Lin Chuan, there will always be a way to solve the difficulties and problems that are about to arise.

After Lin Chuan finished talking to Jiang Wei, Deng Ai and Cao Chong about the next plan of the Hanzhong Chamber of Commerce, he began to prepare to go to Wujun in Yangzhou.

Lin Chuan planned to go to Wujun to see the launch of the treasure ship for trial voyage with his own eyes, and then go to Yecheng to meet Cao Cao.

As for whether the treasure ship can really complete the test of launching sea trials this time, Lin Chuan actually has to put a question mark in his heart, after all, this is the first time that the entire Great Wei has built this kind of large ocean-going vessel.

Although there are complete manufacturing drawings and processes, there is no 100% guarantee that the first treasure ship will be able to meet the final requirements.

"I hope that this finished treasure ship will not have any major problems when it is launched for sea trials......"

Before Cao Jie, Jiang Wei and Cao Chong packed up their salutes and prepared to leave, Lin Chuan thought in his heart.

Deng Ai, who really wanted to experience the scene of the treasure ship launching and sea trial, could only stay in Hanzhong to deal with government affairs in the end.
