After that, another day or two passed, and there was no news from the Zongfu about the negotiation of "Yuanyang Guo's request to recover Bolangsha", which undoubtedly means that Zhao Hongrun's non-violent threat had an effect, and after weighing the pros and cons, Zhao Wenkai, the king of Yuanyang, still made the choice as Zhao Hongrun expected, and finally chose to acquiesce.

It can be seen that Zhao Wenkai, the king of Yuanyang, is also a more rational king, although he is angry or unwilling in his heart, he still chooses a situation that is also beneficial to himself, which makes Zhao Hongrun remember this distant uncle in his heart.

After all, it is indeed not an easy task to make such a rational choice.

For example, if two people are walking on the road together and they find a 100-dollar bill, but one of them asks for 99 yuan and only gives the other person only 1 yuan, will this "other person" choose to accept this unfair distribution, or simply break up and simply hand over the note to the police?

From a rational point of view, even if it is only "one yuan", it is a free profit, which is beneficial to "the other person", but in fact, I believe that the vast majority of people will choose the one that no one can profit because of their mental imbalance.

However, Zhao Wenkai, the king of the original yang, curbed the unwillingness in his heart when he was threatened, and rationally chose the option of common profit, which made Zhao Hongrun realize that this distant uncle was probably not good at it.

Comparing his son Zhao Chengxiu, perhaps this is a typical example of the so-called tiger father and dog son.

"When the construction of Bolangsha started, don't neglect the precautions against Yuanyang."

Zhao Hongrun told Cheng Lin, the official of the Smelting Bureau who is responsible for the construction of Bolangsha River Port.

Thinking with his knees, he could guess that Zhao Chengxiu, the prince of Yuanyang who thought he had taken advantage of but caused him a huge loss to Yuanyang, would most likely not be willing to face this matter, and would deliberately do something during the construction of Bolangsha River Port.

But then again, before the other party causes something. At most, Zhao Hongrun could only tell Cheng Lin to take precautions.

In mid-May, after receiving the silence of the Zongfu and the Yuanyang Wang's family, the Metallurgical Bureau and the Ministry of Industry cooperated to start the project, which could take a long time, in Bolangsha.

They first set a fire in the reeds of Bolangsha, burned all the reeds in the marsh, and then used the ashes of the plants. and the sand around Bolangsha, which condensed the marshland as much as possible.

After that, there is the time-consuming and costly piling process, which is undoubtedly the most difficult part of the process of building a river port on this land.

At this time, the smelting bureau's furnace outside the city had been completed, and Langguan Xunxin obtained a large number of unsalable copper ore from the warehouse under the jurisdiction of the Ministry of Households. The ore was transported to the furnace outside the city and smelted into pillars of copper that needed to be surrounded by adults.

In the smelting process, the craftsmen of the Smelting Bureau borrowed from the copper smelting process of the Chu State, after all, Bolangsha is a humid place, and pure copper is very easy to oxidize in a humid environment, in order to make the life of these copper pillars as long as possible, at least more than a hundred years, Zhao Hongrun must not throw the problem of preventing the oxidation and decay of copper pillars to the craftsmen of the Smelting Bureau.

I have to say. In the context of contemporary processes, how to delay or even prevent copper oxidation in a humid environment. It's a very difficult thing.

However, in comparison, it is more difficult to create a copper pillar of corresponding length.

You must know that the bottom of the swamp of Bolangsha is not flat, some places are deep, and some are shallow. This makes it extremely difficult to smelt copper pillars.

Even in the end, they could not come up with the best way to solve this problem, and the craftsmen of the Smelting Bureau could only choose to learn from the process of copper welding in the Chu State, and adopt top welding for those copper pillars that had fallen deep and were not high enough.

The limitations of the technological level of the great era make the smelting bureau can only adopt this most stupid method.

But anyway. The Bolangsa project is finally on the right track.

At this time, Zhao Hongrun took Wang Fu and other officials and craftsmen of the Smelting Bureau to Xiangfu Port, which is located on the south side of Daliang.

Xiangfu Port is also an important port in Zhao Hongrun's blueprint, and it differs from Bolangsha only in the water area it faces.

If the water area facing Bolangsha River Port is mainly the big river (Yellow River), then Xiangfu Port is facing the Yingshui waters.

At the same time as Bolangsha was put into construction, the Metallurgical Bureau and the Ministry of Industry also expanded Xiangfu Port.

Yes, Xiangfu Port was originally the only important river port near Daliang, and almost all the materials that the household department supported Yanling were transported on ships in this river port, and then transported to Yanling.

According to visual observations, there are a total of four docks in Xiangfu Port, which can allow eight ships to berth or carry supplies at the same time, which is not small in terms of scale, but even so, Zhao Hongrun is still not satisfied with its scale.

After all, the ships moored here in the past were all ships with a length of only five or six zhang (one su zhang is about two meters), which was the transport ship commonly used by the warehouse department in charge of transportation under the jurisdiction of the household department, and after seeing the large transport ship of more than ten zhang long in the Chu State, the small boat of five or six zhang in the original Wei State had long been eliminated in Zhao Hongrun's heart.

"Your Highness, please see."

Wang Fu, the director of the Metallurgical Bureau, took Zhao Hongrun to the vicinity of a dock in Xiangfu Harbor.

I saw that this dock had been blocked at this time, and many craftsmen from the Metallurgical Bureau were building a transport ship more than ten zhang long here.

I saw this big ship, the design style is obviously different from the ships of the Wei State, if nothing else, this should be a transport ship built in imitation of the warships of the Chu State, after all, when Zhao Hongrun returned the warships captured from Chen County to Xiong Tuo, the king of Xuancheng, he had specially detained two ships.

As for the purpose, it is self-evident to look at the transport ship in front of you that imitates the warship of the Chu State.

"Have you eaten it thoroughly? The shipbuilding technology of the Chu State? ”

Looking at the transport ship in front of him that had completed the construction of the keel base and was laying the deck board, Zhao Hongrun asked Wang Fudao beside him.

Wang Fu hesitated for a moment and said in a low voice: "We have drawn drawings based on the actual objects of those two ships, which seem to be quite clear at first glance, but in fact, some of the parts on the ships, we have not yet figured out why the Chu people designed them like that......

As he spoke, he took out a large stack of drawings of the ships of the Chu State from his arms.

Zhao Hongrun took a general drawing and looked at it a few times, only to see that it was no longer a square-headed ship in the original sense.

The so-called square-headed ship is the design of ships commonly used by the Wei State today, and the first two ends of the ship are square, which looks like a rectangular shape from a bird's eye view.

However, the ships of the Chu State have abandoned the design of the square-headed boat, and in order to reduce the resistance of the water when sailing, the bow position of the ships of the Chu State has gradually evolved towards a narrow one, and it has to be said that this kind of ship has begun to take on the prototype of those general-purpose ships in Zhao Hongrun's memory.

For another example, the Chu people have designed sails that can be adjusted by using ropes, and the sails have also added foresails and tail sails from the old mast sails, so that the maneuverability of this kind of ship to adjust the direction with the help of wind power has been greatly enhanced.

It is no exaggeration to say that if the ships of the Wei State fight with the ships of the Chu State on the spacious water, I am afraid that the probability of total destruction is greater than the chance of defeating the land by luck, and even the number of archers will not be able to recover the difference in strength caused by the backwardness of the warships.

"The copper smelting process is also counted, but this shipbuilding process has also been thrown too far by the Chu State......

Sighing slightly, Zhao Hongrun handed back the drawings in his hand to Wang Fu, and said in a somewhat emotional tone: "For the time being, let's build it by imitating the warships of the Chu State...... The Chu people were not wrong in their design, they shortened the distance between the bows and curled the hull, all to reduce the resistance from the water when sailing...... As for the foresail, it was to quickly turn the boat around......"

Wang Fu looked at His Royal Highness King Su in front of him in surprise, after all, why did the Chu people design the ship like this, the Smelting Bureau thought hard for a while and failed to come to a conclusion, but His Royal Highness the King Su in front of him, as if he knew the truth from the beginning, saw through the benefits of such an improved ship at a glance.

"Human...... Is there anyone who is born to know?'

Wang Fu blinked in confusion, and then said cautiously: "Then...... Built a ship according to this drawing? ”

“…… Not. ”

Zhao Hongrun nodded.

To be honest, he could actually draw a ship design that was more suitable for navigation than the ships of the Chu State, but he eventually gave up.

After all, the improvement of the process needs to continue to accumulate experience step by step, whether it is a successful or failed experience, it is useful, the most taboo is to pull out the seedlings to help grow, so ambitious.

For example, now that his smelting bureau has not even been able to understand the more advanced Chu warships, and he can't understand the reason why the design was improved like that, Zhao Hongrun suddenly threw the design drawings of the ironclad ship to the smelting bureau, what effect can this play?

There is no seamless welding, there is no iron plate manufacturing process, even if the Metallurgical Bureau is desperately trying to build it, most of it is just a concept ship that cannot be launched and sinks as soon as it swoops.

In this kind of thing, the most important thing is that the Metallurgical Bureau has to understand the process by itself, and Zhao Hongrun plays a role in guiding the direction at most.

After all, he is not very clear about this aspect of things, and cannot explain it to them systematically, so it is better to let them accumulate valuable experience on their own than to give them a wrong idea, after all, the most critical factor in the material change of things still depends on the quantity.

"Just imitate the ships of the Chu State. …… After the completion of the project, it will be delivered to the warehouse, and they will be given a cost price for the time being. ”

"......" Wang Fu looked up at Zhao Hongrun in shock, and said in his heart, isn't this a benefit to Kurabe for nothing?

As if to see through Wang Fu's thoughts, Zhao Hongrun reminded with a smile: "Don't forget the original intention, whether it is to build a river port or build a ship, our original intention is not to make money......

Hearing this, Wang Fu suddenly woke up and nodded with relief.

Indeed, the purpose of their smelting bureau in building river ports and shipbuilding was only to increase the transportation capacity of ore and other raw materials to the girders. (To be continued.) )
