The upgrade of the level 3 iron-making room is successful, not only can you build siege building vehicles, but also adds 3 additional military power technology points to Lei Zihao!

Coupled with the military force technology points accumulated in the first two levels, Lei Zihao already has a full six military force technology points!

The military power technology point can be from the total war system, the consumption of the limited technology provided by the exchange system, after the completion of the level 3 iron-making room, Lei Zihao's military technology exchange list appeared in a few inconspicuous military technology!

Lei Zihao couldn't help but think of the situation that after he saw those low-level military technologies, he didn't waste a little bit of military power science and technology in independent research and development, I wonder if he can continue independent research and development this time?

[Shield Resistance (Military Technology Requirement 3): On the battlefield, when the infantry is still in place, the impact damage from the enemy cavalry will decrease, and the troops with large shields will learn to use the 'Tortoiseshell Array', and turning on the 'Tortoiseshell Array' can reduce the casualty ratio caused by the enemy's arrow shots.

Unification of Military Orders (Military Tech Requirement 3): Mercenaries in the army have a reduced chance of "defection". 】

These two extra military technologies are too low for Lei Zihao!

Needless to say, Lei Zihao had already handed over to the soldier instructor Antonio, and now the soldiers who came out basically learned this trick, and there was no need to exchange it at all!

The unification of military orders was even more when Lei Zihao set up a servant army, and the planning of the establishment was completed and the military orders were unified!

These adjustments and progress that still need to be made in ancient times, for Lei Zihao from the 21st century, it is really not a difficult problem, after all, Lei Zihao is a mercenary, and he knows more about military knowledge than the generals of this era!

Therefore, not long after the appearance of these two technologies, the words "completed" appeared in the back, and Lei Zihao once again completed the 'feat' of not losing a little military force technology points, but unfortunately, this time Lei Zihao did not have the slightest sense of achievement......

"Hey, I hope that the military technology that appears next time will be something I won't, otherwise, these accumulated military force technology points will be wasted......"

Different from civilization technology points, military power technology points have no other role except for the military technology provided by the exchange system, while civilization technology points are non-depleting technology points, when a certain number is reached, a certain stage of people's livelihood technology will be automatically activated, according to the explanation of the total war system, when the civilization technology points reach a certain number, the entire total war system will be evolved!

It's just that today's Lei Zihao only knows that upgrading to a level of academy building can increase a little civilization technology points, this academy building is still the only one, Lei Zihao has only two poor civilization technology points so far, even if he completes the upgrade of the level 3 library, it is only 3 points, and even the lowest-level people's livelihood science and technology long bricks need 3 civilization technology points to open!

Obviously, the real way to obtain civilization technology points is not simply to rely on the upgrading of academy buildings!

Therefore, Lei Zihao can only forget about this civilization technology point that is not clear now, the most important thing for him is to upgrade and riot soldiers, and other things will be talked about after she grows stronger......

A few days after the completion of the Level 3 iron-making room, the Level 3 Library, which was also opened by Lei Zihao, was completed!

At the moment when the library was built, Lei Zihao got the prompt tone of Zhuge Liang's attribute promotion, which was directly subordinate to the civilian class in the library, and Zhuge Liang got an additional attribute of a science enthusiast!

At first glance, this attribute is useless, but it only increases Zhuge Liang's love for the study of objective things, and develops his brain circuit a little, that is, it makes Zhuge Liang a little smarter......

However, in the notes of the system, it is shown that science enthusiasts are a prerequisite for the appearance of rare affairs officials such as scientists!

It's the kind of real scientist, not a scholar who studied Bagu literature and philosophy in ancient times!

That's not a lot of good news......

Before the level 3 library is upgraded, the level 3 stone brick avenue and the level 3 ground drinking water canal have been completed, and only the gladiatorial arena has not been built for the regular upgrade buildings!

This also made Lei Zihao confirm that the building upgraded from the original building has a much shorter construction period than building out of thin air!

When only the gladiatorial arena was left in the regular buildings, those additional separate level 3 buildings were also built one by one, and the first to be completed was the mint that Lei Zihao was looking forward to the most!

Lei Datou can finally start casting! And Lei Zihao can also collect some more seigniorage, which is invisible, and it is all done with currency, which will not cause any fluctuations in public opinion!

After all, the exquisite shapes and patterns are worth the quality of the gold and silver precious metals that are missing!

After the completion of the mint, Lei Zihao carried out a large-scale restructuring of the monetary system of the entire Longhan City!

The mint mainly produces three kinds of currency, one is a small copper coin, which is a round copper coin, which is similar to the original copper plate, but the copper content in it is inevitably reduced......

The small copper coin is the most basic currency, and it is also the most commonly used currency by civilians!

The higher level is the small silver coin, which is much smaller than the original silver coin, but the pattern is more exquisite, and the official exchange rate given by Lei Zihao is that 10 small copper coins can be exchanged for a small silver coin!

On top of the small silver coins are the big silver coins!

It is said to be a large silver coin, but it is actually not much larger than the original silver coin, and it is printed with a delicate profile bust of Lei Zihao, which belongs to the largest currency under the reign of Lei Zihao in the future......

As for gold and gold coins, they have naturally become official precious metals that only enter and cannot be exported!

The proportion of gold coin resources converted from gold is very high, Lei Zihao will never allow gold to circulate in the market, he wants to collect all the gold for upgrades and riots!

The most important thing is that gold coins are too valuable for civilians, and only merchants will use them for bulk trade, so canceling gold coins and replacing them with large silver coins whose value is far inferior to gold coins has no impact on the lives of civilians, and it is not a big problem for merchants, it is a big deal to carry more thunder heads......

The metal currency produced by the mint is very fine and corrosion-resistant, and it is also easy to carry, which is convenient for the people's lives, and Lei Zihao is not a black-hearted businessman, so the precious metal content of the currency is infinitely reduced......

Lei Zihao just earns a seigniorage, whether it is a large silver coin or a small silver coin or even a small copper coin, the precious metal content is relatively conscientious!

One large silver coin equals 10 small silver coins equals 100 small copper coins!

The completion of the mint allowed Lei Zihao to ban the circulation of gold currency in the real sense of the word in Longhan City and Megara City!
