Yang Yifei woke up from his twenty-square-meter bed, and Flavi and Kasha were sleeping soundly in his arms.

If it is defined according to the cognition of ancient China, Flavi and Kasha are equivalent to his main wife and peaceful wife, and other women are naturally concubines.

However, Yang Yifei is the emperor in this world, so Flavi and Kasha are equivalent to the empress and imperial concubines, and Nataya and Asila and others are concubines.

It's just that there is no such saying in this world, Yang Yifei's women, except for Flavi who is the queen, other women are called Mrs.

But it's not bad! Although the women also have their own small circles, they have a good relationship, Yang Yifei has always had a bowl of water and a flat bowl of water, rain and dew, and no one will compete for favor or anything.

The most important thing is that Yang Yifei's women are all professionals, they all have their own careers, their own areas of responsibility, and they also have to practice.

Naturally, it will not be the same as those women in the ancient harem of China who have nothing to do all day long and can't find anything else to do except Gong Dou.

The women all had their own residences, but Flavi and Kashya were the most intimate, and the two sisters always slept with Yang Yifei together.

For the others, the three Rog sisters, Hanna, Lysha, and Eliza, usually serve Yang Yifei together, while Asila and Nataya are used to being alone.

In the past fifteen years, with the help of Yang Yifei's projection, these women have successively comprehended the law, evolved super genes, and have a long lifespan.

Fifteen years have passed, and their looks have basically not changed, only become more feminine.

After Yang Yifei woke up in this world, the memories and abilities of the projection quickly merged with the ontology.

Fifteen years of cultivation and various laws needless to say, the projection of this world is the same, all the laws are comprehended, and even deeper than the projection of the mythical world, which makes Yang Yifei's strength increase significantly.

In addition, there are some new magic created by himself, which is better than nothing, because with the system engine, all kinds of magic methods are at his fingertips? It makes sense to play any way.

Then there is the question of the development of the world? The development of a world, or a country? It is nothing more than looking at the five major aspects of politics, military, economy, science and technology, and culture.

Nothing to say about politics? The entire dark world was unified by Yang Yifei, this continent with only two continents, east and west? The planet, which is no larger than the size of the Eurasian continent and has a population of less than 30 million, was named "Roger Star" by him.

Is the current form of government still a feudal empire for the time being? Because the conditions for the implementation of a constitutional monarchy are not yet ripe? He lacked talent in all fields, and the natives were not capable of meeting the conditions he demanded of a cabinet.

This aspect of the military is linked to science and technology and culture, fifteen years ago, after the unification of the Roger Star? Yang Yifei immediately opened the Roger Career Academy in Canduras? Rogge Compulsory Education Academy, and Rogge Institute of Science and Technology.

The dean of the Rog Profession Academy is Archangel Tyrell, and the heads of each department are Asila and others, there will be no shortage of professors, and now there is no threat of demons in the continent? The professional legacy flourishes.

Luoge Compulsory Education College includes four parts: primary school, junior high school, high school, and university, and the dean is Yang Yifei himself? It mainly provides compulsory education to the indigenous people of the mainland, and popularizes mathematics, physics, chemistry and biological knowledge.

The president of the Rogge Science and Technology Research Institute is Decca Kane? Chasi, Farah, Hera Tieli, Lessander, Zogeland and others are all professors at the Institute.

Twelve years later, the first gains in knowledge in Canduras? The first batch of high school students graduated? Except for a small number of people who go to university to continue their studies? Others were sent to Lu Gain, Kurast, Kartim, Kegistan and other places as teachers to carry out a new round of cultural popularization.

Now in its fifteenth year, the first batch of college students will graduate in one year, and they will enter the graduate school for further study, and at the same time join the research of science and magic.

Magical knowledge is a thing that is biased towards the side of science and technology, although it is not easy to master this power, but the principles of various magic can be explained by technology.

For example, the question of how lightning is generated, if you are a professional, he will tell you that it is to use magic runes to convert the magic elements emitted by itself into thunder elements, attract the thunder elements from the outside world, make them resonate, and finally lead the lightning down to attack the target under the effect of spiritual power.

And if it is a college student, he will tell the professional that there is negative electricity in the thunderclouds in the sky, and the thunder element formed by you with magic elements is positive electricity.

The so-called positive and negative attract, the two are attracted to each other by the magnetic field, so the thunder and lightning in the sky fall to the ground, forming a connected electric snake between the heaven and the earth, in which the role of spiritual power is to determine the landing point of the lightning.

Look! Magic and technology are inherently interconnected, they don't need to understand why magic runes can convert pure elements with no attributes into thunder or other elements, they just need to know that magic can do this.

The biggest role of these scholars, who do not have professional qualifications and cannot cultivate the inheritance of professionals, is to create various scientific and technological products, and then cooperate with professionals to integrate magical magic into various scientific and technological products.

However, the students are still learning, and the research institute is mainly Dekka Kane, who is tinkering, and under the leadership of Yang Yifei, they have created magic motorcycles, tractors, cultivators, large and small ships, and the like.

There is also a large-scale magic power station with the magic array as the core, and magic lamps have been popularized throughout the continent.

All kinds of machinery, such as lathes, punches, milling machines, bench drills and other machinery have also been created, but at present, they are still manual for the time being, and the CNC is not yet available, which requires the productivity and scientific and technological level of the whole society to be improved.

At present, the level of magic technology of Roger Star is about the level of the Earth during World War II, and Yang Yifei is sure that there should be no big problem in entering the digital information age of pre-nuclear civilization within a hundred years, and two hundred years is enough to enter the aerospace age.

They must also enter the Space Age, because the Rog Star is too small, and there are only so many resources, if they do not enter the Space Age as soon as possible and obtain the resource planet, their resources will soon be depleted at their development speed.

Tyrell's vision is still very long-term, after all, he understands the situation of some advanced civilizations in the universe, and knows that future development resources are the top priority, so he even had the idea of hell.

In less than fifty years, they will be able to build a nuclear bomb and truly enter a pre-nuclear civilization, and by that time, the demon of hell will be their younger brother in front of them.

In fact, the current Hell Demon is already a younger brother in front of them, and the tanks, armored vehicles, and helicopters left by Yang Yifei have all evolved into the magic version.

Not only energy, but also many other magic circles have been carved on those war machines, such as those that strengthen defense, increase speed and sensitivity, never wear out, increase fire damage, explosion damage, and so on.

Nowadays, even an infantry fighting vehicle with the weakest combat power can be called an artifact, if there were these things in the past, where would Yang Yifei still need to run on two legs? Directly drove the tank and helicopter all the way and ran over it.

With the current combat power of the Luoge Liberation Army, if you want to fight hell, the demon really has no power to resist.

Even all of the guns have been turned into magic guns, and although the guns are too small to solidify the magic circle that will never wear out, one of the magic circles is called "Restore durability in 33 seconds".

In other words, the wear and tear of the barrel and parts of the gun will recover every 33 seconds, which is not much different from never wearing.

After all, it is impossible for soldiers to fire 24 hours a day, as long as they rest for one night, the durability of the guns will return to their peak value, and the wear and tear will be restored.

In addition, the guns are also solidified with the runes of magic bullets, which are derived from Amazon's magic arrows, and although the rate of fire cannot keep up with the rate of fire of automatic weapons, it can also be used as a semi-automatic weapon.

Originally, the fighters often used semi-automatic mode to shoot AKs, shooting single shots, so that even the logistical pressure did not exist, because the gun did not need ammunition.

So it's still reliable to fight hell, and now there are only two demon kings left in hell, Azmodan and Belil, and no matter how many they are, they can't withstand the attack of their demon guide army.

The Hell has a huge amount of magic crystals, mythril, and gem ores, as well as metals such as gold, silver, copper, iron, tin, etc., which are exactly what they need.

Yang Yifei put this proposal on hold for the time being, and he didn't say that he wouldn't adopt it, but at present, Luo Gexing has just stabilized, and the people's good life has not passed for a few years, so it is not appropriate to start the war at this time.

So he planned to wait for a few more decades, when magic technology was further improved, at least after he had a nuclear bomb, and then it would not be too late to invade hell.

The so-called Hell is just the definition of the world where the demons are located by the Rogers, but in reality it is just another planet.

According to the definition of that world in the supergod universe, it seems to be called a giant civilization.

The creatures of that world, except for a few races, such as the Styx Doll Clan, the other demons are all developing towards gigantic, and the larger the size, the stronger the strength, including the Sinking Demon Clan.

As I said before, the Sinking Demon Clan became so short because they were angered and cursed by the Demon God, and the original Sinking Demon was also very tall and mighty.

The plan to invade Hell has been put on hold for the time being, and the resources of Rog Star are enough for them to use for hundreds of years, and in a few decades, there will be no time at all.

Fifteen years later, as food became plentiful and the world's population grew, the world itself was home to a variety of high-yielding crops, with potatoes being the main food.

With the seeds of other crops provided by Yang Yifei and the invention of the magic cultivation machinery, the grain output naturally increased greatly, and Luo Gexing was no longer in danger of being short of food.

In short, the development of this world is very rapid, and its unique environmental advantages are incomparable to the mythical world, magic plus technology, it is not as simple as one plus one is greater than two, and the development speed has increased at least several times.

After all, although technology is just beginning, magic has been developing in this world for thousands of years, and it has long been too mature to be mature, and even has entered the stage of prosperity and decline.

After the demon was defeated by Yang Yifei and the lost inheritance was recovered, the magical civilization entered the era of revival and flourished again.

Among them, the various magical knowledge of the Heradic clan collected and preserved by Dika Kane played a crucial role.

If Yang Yifei is a generation of great men who liberated the whole continent, then Dika Kane is a generation of sages who revived magical civilization.

During the rest of the dark world for most of the year, Yang Yifei installed the red queen that he had specially copied in the biochemical world, installed it in the research institute, and gave Dika Kane and several people second-level permissions.

Knowing that he was going to come to the dark world, he would naturally not be unprepared, although he didn't do anything else when he went to the biochemical world this time, he made several copies of the supercomputer of the red queen, so that in the future, the red queen will have the opportunity to travel all over the heavens and all the worlds.

Then he used a memory memory downloader to download the knowledge of mathematics, physics and chemistry and passed it on to every college student, so that they could graduate a year early.

Now that there are university professors, Yang Yifei can be liberated to do something else, and the knowledge in the Red Queen database is very high-end, and it has reached the level of the 21st century.

With the Red Queen, the scientific and technological progress of Roger Star will be further accelerated, but Yang Yifei is very cautious about the knowledge of biochemical technology in the Red Queen database, especially the use of the Perfect T virus.

It's definitely going to be used, but it's not for a lot of use, and only the most loyal people who have stood the test of loyalty will get the perfect T-virus with super genes.

Viruses are different from other drugs, they can divide and multiply on their own, and they can multiply indefinitely as long as they are provided with enough nutrients.

In other words, he only needs to take one perfect T-virus and turn it into 100, 1,000, or even countless of them.

……

At the end of the break, Yang Yifei returned to the system space with great expectations, I don't know what level this world will develop to next time, I hope that the satellite belonging to the Rog Star has been lifted off!

Back in the main world, Yang Yifei is still obscenely developed, and now all 1225 clones have not been cloned, and the individual strength of the clone corps is not enough, and the genetic evolution caused by the perfect T virus takes time, so at present, it is still mainly based on the development of armaments.

Yang Yifei has been in the dark world for more than half a year, and he has changed all the weapons and equipment he pulled at the end of the last experience, this is the real magic change, transformed into a magic version, isn't it a magic change?

After returning to the Overworld this time, he built a large arsenal again, and last time he pulled 50,000 sets of individual equipment, and took 5,000 sets out and put them in this arsenal.

In addition to this, there are 10 Apaches, 10 Black Hawks with 100 bases each for ammunition, 50 assault vehicles, 30 infantry fighting vehicles, 20 tanks with 50 bases each for ammunition.

In terms of military integrity, one base of ammunition contains 16 rounds of Hellfire missiles and 1,200 rounds of 30mm M-230 chain gun shells.

In other words, the ammunition alone contains 1,600 Hellfire missiles, 120,000 30mm chain gun shells, plus tanks, armored vehicles, and individual weapons, which is enough to fight a large-scale battle that lasts for several months.

Even if the enemy is a martial artist and a cultivator, and the cultivation does not reach a certain height, he will only be deflated in the face of these magic equipment.
