my fortress

Chapter 460 "The Age of Steel"
After reading all the contents of the dialog boxes that popped up, Yifei found that after the fortress was upgraded to two stars, only 2 of the benefits he got could see the actual effect immediately.

One is the improvement of personal strength.From the previous holy-level combat power to the current king-level peak.As for how much he has improved, after sorting out the information instilled into his brain by the system, he immediately knew that with his current strength, he could basically run rampant in the Western Continent.

Hahaha, super god-level combat power!At this time, Yifei thought of Yiyi whom he first met in the Khajid Mountains, and heard people talk about his glorious past, and how he drove away all the troops by himself.Immediately, Yifei became a little proud. With his current strength, he can finally go out and pretend to be 13 openly, without worrying about any danger!
Thinking of this, he was very proud, and immediately went to check another benefit that could be effective immediately, which was the so-called energy guardian product of the three-star civilization. He really wanted to know whether it was powerful or not.

Energy Guardian: The city guardian formation produced in the age of mana, with sufficient energy, can resist any attack below the three-star civilization!

Fortress formation!Looking at the introduction of the energy guardian, Yifei immediately thought of where to place it.This kind of weapon for guarding the house, of course, must be placed in Wild Wolf City, a city that is inland but has a precious fortress!
As for Chang'an City, he is quite at ease. After all, it is suspended on the sea, and its geographical location is more advantageous. Moreover, the sea is guarded by a fleet, and the sky is guarded by those sky monsters of the Iron Cliff tribe and a large number of air riders. As far as Wild Wolf City is concerned, its safety factor is unknown how many times higher.

After appreciating the two benefits that can be seen immediately, he opened the system interface, wanting to see what new changes will be made to the system interface after entering the Iron Age!
As the system interface opened, at first glance, he found that the things in the system interface were still the same as before, without any essential difference.But with the opening of one column after another, he found that a new building appeared in each of the town buildings and military buildings!

Inscriptions of Steel: town buildings, wonders, records of the discoveries and developments of all major civilizations in the Iron Age.The number of buildings that can be built is 1, and the prestige value of the city is +1000.

Iron and Steel R&D Academy: Military building, where various steel research and development can be carried out!
After reading the introduction of the newly added buildings in the system interface, he found that there was a small spherical mark on the small map on the left side of the system interface.A little curious, he directly clicked on the small sphere, and a virtual frame popped up in front of him.

Kowloon Space Topographic Map!
Looking at the line of words displayed on the top of the virtual frame, he immediately knew that the small ball was used to view the map of the Nine Dragons space he had just obtained, so he opened it, and the map of the Nine Dragons space came into his eyes. At the same time, a brief introduction also appeared in front of his eyes.

The spatial area of ​​Kowloon: the land area is 320 million square kilometers, and the ocean area is 130 million square kilometers.Among them, the plain terrain accounts for 78% of the land area, and the mountains are rich in antimony ore.

After reading the brief introduction that popped up in front of him, Yifei immediately discovered that this Kowloon space is simply a very good base camp, with the size of its land, hundreds of millions of people can live in it.Especially here is also rich in antimony ore, it is simply a treasure!

Thinking of this, he placed the newly acquired fortress in the Jiulong space, and at the same time set the function of the guardian statue of the jade rabbit standing outside the wild plateau, so that it only guards those who are loyal to him.

Now that the agreement between the three parties has been voided, he doesn't mind occupying the wild plateau and making it a hidden base, which can be regarded as leaving a way out for himself.

What's more, this space is not only fertile, but also rich in such important strategic resources!

Now he doesn't know what role antimony ore can play in the Iron Age, but he knows very well that once he raises the kingdom to level four and enters the technological age, the use of antimony ore will be revealed.

As the fortress replaced the previous black castle, rows of city walls rose from the ground, coiled layer by layer on the mountain. From a distance, the entire mountain was like a nine-story pagoda with distinct layers.Immediately afterwards, various town buildings rose from the ground, and a large number of residents poured out of the fortress and entered the houses and town buildings everywhere. An hour later, a huge city appeared on the map.

Seeing this scene, he pointed to the open space on the top of the mountain and said, build the inscription of steel!Immediately, a dialog box popped up in front of his eyes.

[Registrar: The inscription of steel, a two-star civilization wonder building, it takes 60 days to build this building, is it going to be built, is it?no? 】

yes!Looking at the prompt given by the system, he chose yes in his heart!Immediately, a large group of people appeared in the open space of the mountain, busy there.

Seeing this scene, he chose an open space again and built the Iron and Steel Research and Development Institute.

Looking at the Iron and Steel R&D Academy that appeared on the map in an instant, he clicked in, and a virtual frame was displayed in front of his eyes, and he immediately knew what the Iron and Steel R&D Academy was for.

Ordinary steel research and development.

Ordinary steel research and development: strength research and development, hardness research and development, density research and development, corrosion resistance research and development...

High-quality steel research and development: strength research and development, hardness research and development, density research and development, corrosion resistance research and development...

Research and development of special steel.

High-quality carbon steel: strength research and development, hardness research and development, density research and development, corrosion resistance research and development...

Alloy steel: Same as above.

High alloy steel: Same as above.

At this time, Yifei discovered that the Institute of Iron and Steel Research and Development turned out to be a place purely for the study of various steel materials. After understanding the role of the Institute of Iron and Steel Research and Development, he couldn't help but have a bad guess in his heart. It was different from the Iron Age he had imagined.

According to his thinking, the massive application of steel should be the arrival of the industrial age.And the advent of the industrialization era indicates that he can enter the era of hot weapons from the era of cold weapons.

If he really entered the era of hot weapons, it would be a breeze to think of conquering this world.However, the various functions displayed in this newly added building made him feel disappointed. All of them were research and development technologies of various steel materials. It really deserves to be called the Iron and Steel Research and Development Institute. There is only one place for steel research.

Just as he was complaining in his heart, a dialog box popped up in front of his eyes.

[Registrar: Your Majesty the King, in the era of industrialization, heavy industry is the most important criterion for measuring the strength of a country, and steel is the foundation and pillar of almost all heavy industries, and is also a necessary material for construction, so...]

System, I understand what you said, I just want to know how to step from the era of cold weapons to the era of hot weapons!Looking at the explanation given by the system in front of him, Yifei asked directly in his heart.

Immediately, a large amount of information flooded into his mind. After sorting out all the information in his mind, Yifei found that the hot weapon era defined by the system was completely different from what he remembered.

According to the definition given by the system, as long as he upgrades the fortress to 4 stars, that is, enters the era of technology or the era of biology, he will officially enter the era of hot weapons.

And before 4 stars, they are laying the foundation! At 2 stars, that is, the age of steel, the focus is on the research and development of various materials, mainly steel; At the same time, the achievements of the previous three eras can be combined to formally enter the stage of comprehensive application.

After understanding what was going on, he suddenly discovered that after entering the Iron Age, he may have more advanced steel technology than that of his previous life, but he could only make the steel armor of his soldiers stronger and their weapons sharper.

Violence!Thinking of this, he couldn't help sighing in his heart!

But the result of the matter is already like this, and he can only bear it very aggrieved, hey, with such a high-end steel craft in his hands, he can only watch, anyone who has this kind of thing is aggrieved!
　I'm so depressed, I'm so busy today that I didn't even log in to the background. I just logged into the background and found that the automatic setting has not been sent yet. When I was wondering, I found that the setting was 05-18, and I fainted!Sorry, my friends! !
