Leaving this time, I don't know how long it will take to see Li Mochou again, because on the night after the reminder at the end of the experience sounded, Yang Yifei fell madly in love with Li Mochou several times, making her paralyzed like mud, and then after she fell asleep, she silently chose to return.

System space, Yang Yifei looked at the screen in front of him.

Experience the world: The Condor Heroes

Points in this world: 80000

World Story Change: 100%

Points earned in this world: 80,000

The plot of this world has changed by more than 51%, and it can be returned.

The world operates in the following ways: 1. Time pause 2. Create projections

Looking at the points value of this world, Yang Yifei's spirit was greatly lifted, with this income, his background is even deeper, and some plans can also be implemented.

It's just about the choice of the way this world operates, Yang Yifei is slightly entangled, the benefits of creating projection are obvious, projection can be used to cultivate Jiuyang Divine Skill, maybe next time he comes back, he will be able to have ten or eight years of power out of thin air.

But Li Mochou, like Alice, has never taken the elixir of life, what if she goes back next time, she is already old?

This is not the main thing, the main thing is that the main thing is still the question, projection sleeps with his wife, is that his own sleep, or is it someone else's sleep?

If the next time I come, a kid who runs out and calls him dad will be even more fucked.

A few years ago, because of the failure of the great cause, Yang Yifei and Li Mochou have always paid more attention to the problem of contraception, and every time they are done, they will use their true qi to refine the tadpoles, but what if they project their brains and decide to have children?

The more Yang Yifei thought about it, the more he felt that it was not suitable to create projections in a world with a wife, but this cultivation was indeed a loss, and it was a pity.

He thought about it for a while, looked up the problem in the system help, and the tangle finally disappeared.

It turns out that no matter what world you create a projection, as long as you fuse with the projection, what you have newly learned will enter the projection's memory on its own.

In other words, he has now learned the Jiuyang Divine Skill, as long as it is fused with the projection in the mythical world, then that projection is also equivalent to understanding the Jiuyang Divine Skill.

In this way, the problem was solved, and Yang Yifei chose to go to the mythical world first.

……

After fusing with the projection, a memory melted into Yang Yifei's mind, and eight years had passed since this experience, and Daqin had already completed the accumulation and started the battle again.

The land of Baiyue in the south was swept away with lightning speed, and the remnants of the Six Kingdoms were almost wiped out, and the territory of Great Qin almost reached the size of the Northern Song Dynasty in the later generations.

With a spaceship as a logistical support, the Daqin army did not have the slightest worries, even if it went deep into the grassland, it was not afraid to go to the desert for the time being, not to mention the sandstorm there, not to mention this kind of wooden spaceship, even the planes of later generations could not carry it.

The territory of Great Qin expanded outward at a terrifying speed, and in six years, the land scope of Great Qin had surpassed that of the Northern Song Dynasty and reached the level of the Great Tang Dynasty.

The Xiongnu were driven out of Asia and went to Europe to compete with the Roman Republic, and the northern steppes and the western Tibetan Plateau became the pastures of Daqin, with herds of cattle and sheep and majestic horses.

Then the First Emperor ordered to enter a new round of recuperation, and now the land area has risen sharply, but the population of Great Qin is somewhat unable to keep up.

Originally, the population of Great Qin in history was only between 25 million and 30 million, but when Yang Yifei left last time, the population of Great Qin had exceeded 40 million.

Since the advent of high-yield crops such as potatoes, sweet potatoes, and corn, the population of Daqin has grown wildly again in the past eight years, and has been infinitely close to 60 million.

But it is still not enough, according to Yang Yifei's estimates, the land of Daqin today has almost exceeded 13 million square kilometers, far higher than the 9.6 million square kilometers of the later republic.

You must know that in the 9.6 million square kilometers of later generations, there were 1.4 billion people living in them, and now there are only 60 million, where is enough?

Yang Yifei advised the First Emperor to make the next edict to encourage childbearing, and in view of the fact that the treasury has been repeatedly expanded, but it is always full, the First Emperor agreed to this edict.

His Majesty's Edict of the First Emperor of Great Qin: All the citizens of Great Qin, the strong should not marry old wives, the old should not marry young women, women should not marry seventeen, and men should not marry twenty, and their parents are guilty, regardless of whether they are high or low, they will be sentenced to one year of forced labor; The pregnant woman will give birth to the official and make the doctor keep it; Male born will be given ten gold and one ox, and female will be given ten gold and one sheep; gave birth to three children, two of whom were raised by the official, and two children were born, and one of them was raised by the official.

This decree seems to be very advanced, and even later generations have dared to issue such a decree, but in fact, similar edicts have appeared in the Spring and Autumn Period of China, and the first to be implemented was the Yue Wang Goujian.

In that year, the Yue Kingdom was defeated by the Wu State, and the Yue King Goujian was defeated and lost his teeth, so he wrote this decree, and the population of the Yue Kingdom really increased greatly in a short period of time.

However, in order to support such a decree, the country's economic level and food reserves must be sufficiently abundant, otherwise the decree will be a joke in the end.

But Daqin is now fully qualified to issue such a decree, a few years ago, potatoes, sweet potatoes and corn were only used to supply people, but over the years, because the output of this thing is too high, and it is not picky, it has gradually become more and more, and many of them will rot every year.

Therefore, in recent years, even domestic animals have begun to eat sweet potatoes and corn, so the number of civilian livestock is also increasing, and the meat quality is getting better and better.

As soon as this decree was issued, Daqin set off a vigorous man-making movement, and midwives became the most promising profession.

After entering the stage of recuperation, Yang Yifei basically no longer cares about military and political affairs, but focuses on invention and creation.

The four major inventions were made up by him one by one, especially the invention of papermaking, which made the first emperor very excited, laughing and patting Yang Yifei on the shoulder many times.

He can finally end the days of dealing with "more than 100 catties of government affairs" every day, and all kinds of previous reports are engraved with bamboo slips, which is not an exaggeration, and he really has more than 100 catties of government affairs to deal with every day.

If you want to approve it, you have to use a knife to engrave it, which is inefficient and laborious, but now that there is paper, Yang Yifei has made this kind of thing out, and the efficiency of handling government affairs has been greatly increased, and the first emperor is also a lot easier.

The invention of the compass marked the beginning of the Great Qin's Age of Discovery, which was of unparalleled significance to the Great Qin's global conquest.

Printing combined with papermaking made Daqin's collection of books from a pile of bamboo slips to a booklet.

And the most far-reaching impact on Daqin is naturally gunpowder, not only the army's combat power has increased greatly, but it is even more invincible in this era, and even the social productivity has also increased a lot.

In the past, when opening mountains and building roads, when encountering big mountains and rocks, they could only rely on manpower to knock and chisel a little bit, but now a bag of gunpowder can save dozens or hundreds of people a few days.

It's just that Yang Yifei is still hesitant to push the agrarian society to the industrial society now, after all, the pollution and damage to the earth by the industrial society is too serious.

In these major events that are enough to affect the whole world, projection will not make decisions without authorization, so after Yang Yifei fuses projection this time, he needs to think about this issue.

In the end, after Yang Yifei's careful consideration, he decided to let it go first, and wait for a few more worlds to look at it, maybe he will come into contact with the world of cultivating immortals in the future, and he can come to this world to spread the cultivation of truth, so that Xianqin can evolve into "Xianqin".
