"Huh" by the sea, Zhang Hao looked at the vast ocean alone and breathed a long sigh ......of relief.

I haven't relaxed for a while, and I'm not even in a good mood to practice. And all this is because Zhang Hao is conceiving the 'Dayang Group'.

Now, with the help of many parties, especially with the help of the critical moment of the political situation change in the country of Qixia, the expected goal has finally been achieved. However, now is not the time to relax, because there are still bigger challenges ahead, and there are many more.

In the short term, this is advantageous, because the Zhang family can greatly rely on the power of the Dayang Group to rise and influence the whole country through the Dayang Group, but in the long run, it will make the Zhang family fall into a certain passivity.

Therefore, in the next period of time, Zhang Hao still needs to be cautious and carefully control the big ship of "Dayang Group".

In addition, the official launch of the stock market, the future stock trading is bound to appear, so the bank also needs to be built, but in this world, how to do the bank, there are many problems to be solved. The first is currency.

In another world, banks need not money, but credit – money as a vehicle for credit. Gold, oil, etc., are all guarantees of credit.

In ancient times, money was the embodiment of productive forces, but in the financial age, money was the embodiment of national strength and national credit.

Therefore, it is very difficult to hold up real banks without issuing credit money such as paper money. But the issuance of banknotes ...... Zhang Hao expressed skepticism. With the ability of a cultivator, tons of banknotes can be copied in minutes.

"Is it possible to use gold and silver as currency?" Zhang Hao said about Adamantite Gold and Mithril, which is made with the value of Pure Gold and Mithril itself, which is of high value and widely recognized, and is inherently creditworthy, so it seems to be a good choice of currency for the time being.

But Adamantite Mithril is too little!

Moreover, once Adamantite Gold and Mithril are circulated, I am afraid that most of them will be made into magic weapons or collected by cultivators, and they will inevitably lose the circulation attribute of currency. This cannot be tolerated.

"Headache......" Zhang Hao hugged his head, and was a little entangled for a while.

Seeing that Hou Shangzhuo and others had completed the inspection of the ironclad ship model, Zhang Hao also returned to the research base.

In addition to currency, there are also a large number of semi-finished steel weapons and armor provided to the city lord, which should also be paid attention to, and with the death of the Great Emperor in battle, the national situation of Qixia is becoming more and more critical, and the construction of the Iron Legion must also be accelerated.

In addition to the Iron Legion, Zhang Hao is more concerned about artillery. Huang Mingshan and others worked tirelessly, constantly overcoming one technical difficulty after another.

When he came to the research base of Huang Mingshan and others, Zhang Hao saw that Huang Mingshan and others were tinkering with an artillery. The gun has a caliber of about 10 centimeters, an outer diameter of about 16 centimeters, a barrel length of about 1.8 meters, and the gun carriage is a four-wheeled type, which can be pulled by a horse, and the lifting is controlled by a screw.

The overall design is rather bulky.

However, thanks to Zhang Hao's guidance, coupled with the relatively solid foundation of Huang Mingshan and others, and the assistance of cultivation ability, the first artillery design was a breech gun, with three rifling lines in the barrel.

The barrel is cast from steel with a certain toughness, and it is bored in the later stage. The machining process is more complicated.

And the shell is directly a structure with a shell. The primer is made of ordinary gunpowder, and the propellant is mainly ordinary gunpowder, mixed with a little high-grade gunpowder, so as to ensure the safety of the gun chamber under the premise of ensuring sufficient power.

Among them, Huang Mingshan and others are carefully and rigorously adjusting and experimenting.

Ordinary gunpowder is sensitive, but not powerful enough, while high-grade gunpowder is powerful enough, but not sensitive enough. For the time being, Huang Mingshan and others solved related problems by collaborating with each other.

The shell is made of high-explosive steel that is hardened at high temperatures, and the steel is hard enough and brittle enough to be shattered like glass, and shrapnel is terrifyingly lethal.

However, up to now, Huang Mingshan and others have only been in the research base, under the protection of the enchantment, on a small scale, and have been kept secret from the outside world.

Zhang Hao looked around the artillery, thanks to the increasingly mature thread technology, the breech of the gun adopted a threaded type, which also solved the sealing problem on the premise of ensuring safety and reliability.

However, for the sake of safety, a latch structure was added.

In terms of the firing pin, the crossbow machine style was adopted - the spring technology still needs to be improved, and for the time being, the firing pin system can only be designed by borrowing the principle of the bow and crossbow.

As for the fuse of the shell, the impact type was used. The front end of the fuse is the firing pin, and the rear part is the hammer, which is attached to the rear end of the fuse when fired, and once the shell encounters an obstacle, the rear hammer will move forward under inertia and hit the firing pin, detonating ordinary gunpowder, and then detonating high-grade gunpowder.

And for the study of artillery and shells, there are new machine tools next to it that are being intensively studied and commissioned.

Zhang Hao watched for a while and was very satisfied with the progress of Huang Mingshan and others. It should be said that the progress of Huang Mingshan and others is beyond imagination.

Finally, Zhang Hao patted Huang Mingshan's shoulder and said with emotion: "Work harder, after finishing the artillery, you will probably be able to rest and relax, and make up for your cultivation."

In order to make up for the lack of your foundation, I have already purchased the Three Turns of Zhujidan from Xinglintang.

You've got everybody!"

Huang Mingshan and the others' eyes brightened instantly. This world, after all, is a world of cultivation!

Then Zhang Hao, Huang Mingshan and others discussed related issues together. Zhang Hao has been a little struggling on specific technical issues, but in the direction of technological development, Zhang Hao can still give some guidance.

During the discussion, Zhang Shengye ran over in a little panic: "Little mouse, the big thing is not good, the border pass is lost, and the governor of Jinyang is driving straight in."

More than half of the 'Jianwu County', the easternmost county bordering the country of Jinyang, has fallen.

And Xingchang County, which also borders the country of Jinyang, that is, where Xinglintang is located, is also a little dangerous. With the strength of Xingchang County and Xinglintang, they can't stop hundreds of thousands of legions. ”

Zhang Hao was suddenly stunned, "It's lost so soon!"

Zhang Shengye nodded, and his words were solemn: "The crown prince has just ascended the throne, but I am afraid that it will be difficult to bear the heavy responsibility." The current country of perched ...... It's dangerous!"

Zhang Hao breathed slowly, calmed himself down, and finally thought slowly: "I'm going to the City Lord's Mansion." The current Ninghe County ...... There may be some big decisions to be made. ”

............

In the east of the country of Jinyang, on the border with the country of Canglan, two embarrassed figures quietly appeared.

"The front is the Burial Soul Valley, and after crossing the Burial Soul Valley, you will enter the country of Canglan!" Wang Ruiyang said in a low voice, his face a little pale.

And Guan Zhengqing looked at the masters of the Jinyang Kingdom who were patrolling around, and whispered: "It doesn't seem to be easy!"
