In the R&D center, Lin Chuan was asking Master Fang about Dawei's existing shipbuilding technology in detail.

According to Master Lu, although he had not participated in the manufacture of large sea ships in the Soochow period, he had heard from craftsmen who had made large sea ships about the styles and manufacturing methods of sea ships.

"Returning to the Hou of Hanzhong, a large sea ship that can sail on the sea, about fifty meters long, divided into three layers, with both sail pulp, and a waterproof compartment at the bottom of the ship, which can sail long distances above the sea."

Master Fang recalled the style of sea ships he had heard of and described them to Lin Chuan.

When Lin Chuan heard this, he couldn't help but admire the shipbuilding technology of the Han Dynasty, and it seemed that even if he was not prepared to manufacture seagoing ships, the existing shipbuilding technology of the Great Wei Dynasty was the world's leading level.

"Does that master know that sea ships have keels?"

Lin Chuan asked the master again whether the big ship had a keel, which was a key structure related to the size and strength of the ship.

"Keel? I haven't heard of this before, but I don't know much about the manufacturing methods of sea ships, and all the information I know is from the mouths of the craftsmen of the shipyard back then, and there must be something missing. ”

Master Fang had never heard of keel structure, and he was blunt about his lack of knowledge about seagoing vessels.

Lin Chuan nodded with some disappointment when he heard this, and then asked Master Fang to continue his research and improvement work.

"Lord Hanzhong, are you planning to build a large sea ship?"

Chen Yuan, who had been listening, asked Lin Chuan at this time.

"Yes, Benhou really wants to build a large sea ship that can sail far away.

Now that the Hanzhong Chamber of Commerce and production bases have spread across all prefectures and counties of the Great Wei Dynasty, the production of raw materials has now become a major problem restricting the development of the Hanzhong Chamber of Commerce.

All Benhou wanted to build large ships and trade with other countries in order to obtain more raw materials for production. ”

After Lin Chuan heard Chen Yuan's inquiry, he explained to Chen Yuan why he suddenly thought of building a large sea ship.

After hearing this, Chen Yuan admired the foresight of Lord Hou of Hanzhong, but unfortunately he had never dabbled in related technology in the manufacture of large sea ships.

However, Chen Yuan still knew something about the Great Wei and Han dynasties, and some things about navigation.

"Lord Hou of Hanzhong, although I don't know how to build ships, I have heard that there have been sea voyages during the Han Dynasty."

Since the Marquis of Hanzhong wanted to engage in ocean trade, Chen Yuan felt that the situation he had heard about back then might be able to help Lin Chuan.

"Oh? Master Chen, let's talk about it! ”

When Lin Chuan heard this, he suddenly became interested.

"Back to Lord Hanzhong, I have heard that during the time of Emperor Wu of the Han Dynasty, our sea ships once arrived in Dongying and the Kushan Empire, selling silk and all kinds of treasures!"

Next, Chen Yuan told Lin Chuan everything he knew about ocean navigation.

"At this time, you have already come into contact with India and India?"

After listening to Chen Yuan's story, Lin Chuan once again admired the wisdom and courage of the ancients.

Then Lin Chuan felt a burst of ecstasy in his heart, it seemed that he was ready to open up ocean trade, and he didn't need to start from scratch at all, Dahan had already laid the foundation for ocean trade.

"So good! It seems that the Hanzhong Chamber of Commerce will be able to develop abroad in the near future, hahaha! ”

Lin Chuan said excitedly to Chen Yuan, Chen Yuan was not as excited as Lin Chuan, but it was indeed a good thing that the Hanzhong Chamber of Commerce could continue to expand.

After returning to the Hanzhong Marquis Mansion from the R&D center, Lin Chuan began to think about plans for seagoing ship construction and maritime trade in his study.

Regarding the manufacture of sea ships, Lin Chuan decided to find craftsmen who really know how to make sea ships, and after fully understanding the manufacturing technology of Dawei sea ships, he decided whether to establish a sea ship manufacturing base for sea ship manufacturing now.

Thinking of this, Lin Chuan sent someone to call Deng Ai to the study of the Hou Mansion.

After Deng Ai arrived, he saw Lin Chuan thinking in the study, so he said loudly: "Old, old, teacher, the student is here." ”

"Okay, Taxi Ride."

After Lin Chuan saw Deng Ai, he explained to Deng Ai his idea and purpose of wanting to build a sea ship.

"Now we need to find craftsmen who have participated in the manufacture of sea ships in Han, so that we can decide when to start the construction of the sea ship manufacturing base."

In the end, Lin Chuan explained to Deng Ai the purpose of calling him over this time.

Deng Ai heard that Lin Chuan wanted to use a large sea ship to do the business of the Hanzhong Chamber of Commerce to foreign countries, and he admired Lin Chuan's ideas and courage even more.

"Old, old, teacher, the student, through the officials of the scholar clan in Hanzhong County, as soon as possible for the teacher to find a craftsman who participated in the manufacture of sea ships, please rest assured, teacher!"

Then Deng Ai told Lin Chuan that he would go back to find someone immediately, and Lin Chuan had always been relieved of Deng Ai's execution ability, so he asked Deng Ai to bring the craftsmen who had experience in building sea ships to the Hou Mansion as soon as possible.

After Deng Ai got Lin Chuan's arrangement, it only took two days to find two masters from Hanzhong County who had participated in the manufacture of sea ships.

Soon the two masters were invited to the Hanzhong Marquis Mansion and received by Lin Chuan in person.

After these two masters came to Hanzhong County, their lives are getting better day by day, and their sons and daughters are also craftsmen in the production base, and their grandchildren are also studying in Hanzhong Vocational Training School.

Hearing that Lord Hanzhong wanted to know about the manufacture of sea ships, the two masters immediately agreed to solve Lin Chuan's doubts.

"Old decay to meet Lord Hanzhong!"

After the two masters came to the Hanzhong Hou Mansion, they said respectfully to Lin Chuan at the same time.

"Hahaha, the two masters don't have to be polite, Ben Hou asked you to come this time just to learn about the manufacture of sea ships."

Lin Chuan saw that the two masters should be over sixty years old, and their words were more cordial.

"Lord Hou of Hanzhong, the old master and apprentice must know everything."

The older master replied to Lin Chuan, Lin Chuan didn't expect that these two masters were still masters and apprentices, it seems that the two should have been craftsmen in the shipyard for a long time.

Next, the two masters explained in detail to Lin Chuan the manufacturing method of large sea ships, and Lin Chuan also listened very carefully and seriously.

After listening to the two masters, Lin Chuan already had a general understanding of the performance of the existing sea vessels.

Nowadays, most of the sea ships are three-masted or four-masted ships, which can sail on the sea, but can only sail within the coastal range.

Therefore, the current sea ships cannot really cross the ocean, and due to the limitation of cargo warehouses and the lack of maritime navigation technology, it is impossible to leave the coast for real ocean voyages.

Fortunately, the existing sea vessels were enough to support the raw material collection work that Lin Chuan wanted to carry out, so Lin Chuan was very enthusiastic and left the two masters to dine in the Hou Mansion, which made the two masters really flattered and respected Lin Chuan even more.
