Eight years ago, the first emperor resurrected in the sand dunes with full blood, and wiped out Zhao Gao, Li Si, and Zhao Kuang by thunderous means, and killed Hu Hai, but forgave the soldiers who rebelled with Zhao Kuang, but all the soldiers under Zhao Kuang's command were demoted to three levels.

Meng Jie was promoted, taking Zhao Kuang's position, Meng Yi Nangong Yan escorted meritorious, each promoted to one level, and then he ordered to set off to continue the eastern tour, and finally completed the eastern tour.

On the way, the First Emperor asked Yang Yifei to continue to tell him about extraterritorial things, and now that the First Emperor has recovered his health, Yang Yifei has no scruples and tells him about extraterritorial things in great detail.

After returning to Xianyang, the first emperor began to reorganize the imperial court in a bold way, set up a system of three provinces and six ministries, and under the suggestion of Yang Yifei, a series of benevolent policies were issued from Xianyang Palace to further win the hearts of the people.

One of the most important decrees was that the people would no longer be forcibly conscripted to build the palace, and those who voluntarily participated in the construction would receive corresponding remuneration.

In this way, what was originally a disaster for the country and the people and caused a lot of complaints has become a good thing, which has made many young people find a way to support their families.

Although this depleted some of the treasury reserves, it was absolutely cost-effective to win the hearts of the people, and the peasant uprising that should have occurred that year was not in sight.

The world is not chaotic, and Xiang Yu and Liu Bang and others naturally have no stage to play, and they honestly stay in Jiangdong and Jiangnan to live together.

After that, the first emperor ordered Xu Fu to be summoned and wanted to order him to refine some more elixirs, but the herald rushed to the East China Sea, but Xu Fu had already gone to the empty building.

According to the herald's report, Xu Fu sailed with 3,000 boys and girls, leaving only a letter to the First Emperor.

The letter stated that he had expected that the First Emperor would let him refine the elixir again, but the refining materials had been exhausted, and he could not do anything, so he led three thousand boys and girls to the sea to find the alchemy materials, and if the materials were found, he would return to Daqin and refine the elixir for His Majesty.

Seeing this, the First Emperor had no choice but to let him go.

In the next few years, the First Emperor gave Great Qin a recuperation, vigorously developed agriculture, and accumulated grain and grass to prepare for the next conquest.

Now that he has an immortal body, time is no longer a problem for him, so he is steady and steady, not in the slightest.

In the past few years, Yang Yifei has repeatedly made new inventions, such as cranes with pulleys, waterwheels to irrigate rice fields, etc., which have greatly enhanced the social productivity of Daqin, but the most epoch-making invention is a little fart from Yang Yifei.

But it was a hot summer day, and it was still difficult to make the First Emperor comfortable just by Bingjian, so Yang Yifei made a hand-cranked iron fan, which was erected behind Bingjian, and ordered the inner servant to shake it.

And the appearance of this fan gave Yang Yifei an inspiration, and he asked the First Emperor for the meteorite, saying that he would build a spaceship for the First Emperor that could fly into the sky.

The First Emperor listened to Yang Yifei's description and was very interested, so he generously handed over the meteorite to Yang Yifei to tinker with.

Yang Yifei first designed the gears, and then ordered the craftsmen to build a large wooden boat with a helicopter-like landing gear below and a cabin roof on it, extending the Daodao wooden arm outside the hull, and the top of the wooden arm was equipped with a bronze card shell.

Then a hole was made in the wooden bottom, and a large hand-cranked propeller was installed in the bottom, one in the stern and one on the roof, and one in the bow on the left, one on the right.

After the wooden boat is built, it is the last step, the meteorite block is stuck into the jam shell on the wooden arm around the wooden boat, so that all the rays of the surrounding meteorites can only be shot into the wooden boat, but will not affect the inside and around the boat, and the wooden boat enters a weightless state without accident.

Then Yang Yifei took several sergeants to board the ship for a test flight, and after he got on the boat, he ordered the sergeant to shake the fan at the bottom of the boat, and the wooden boat slowly rose.

This meteorite is only a ray that can cancel out gravity and create a state of weightlessness, but it does not create a vacuum environment.

There is no air in a vacuum environment, not to mention whether people can survive, there is no air that naturally does not produce wind, and the propeller does not produce thrust, so Yang Yifei's idea is impossible to realize.

The wonderful thing is that this meteorite can create weightlessness, but there is still air in the air, and when there is air, wind will naturally be generated, and the propeller can also have propulsion.

After Yang Yifei let the wooden boat fly to a height of 100 meters in mid-air, he asked the sergeant to stop shaking the fan at the bottom of the boat, and instead shake the fan at the stern, and the spacecraft stopped rising and began to fly forward.

The three fans in the bow of the ship control the direction on the left and right, and the middle one produces a thrust revers, allowing the ship to brake in the air.

Yang Yifei flew around Xianyang City in the sky a few times, and drove the spacecraft back to Xianyang Palace smoothly, and the landing was simple, just shake the propeller on the top of the cabin.

When the spacecraft lands and wants to be docked, you only need to push the stuck door to block the meteorite rays, and the spacecraft can be firmly parked on the ground and will not float.

The test flight was a great success, and the First Emperor was already excited when Yang Yifei had just taken to the sky, what was the significance of the existence of this spaceship to Daqin, he thought a lot in an instant.

The first is transportation, the spaceship built by Yang Yifei is 20 zhang long and 5 zhang wide, which is enough to transport thousands of soldiers or thousands of stones of grain and grass at a time.

The second is that the terrain will be very small and very small in the restriction of the Qin army, regardless of whether it is a high mountain or a big river, I will sweep through the air.

The third is the combat aspect, with this spaceship, fighting a war is equivalent to being invincible first, flying at a height of hundreds or even hundreds of zhang, what means can attack so high?

But they can calmly smash things from the sky, and without any too powerful equipment, they can load a boatload of stones and throw them down, and they can beat the enemy.

When Yang Yifei flew down, the first emperor told him about this, and Yang Yifei immediately sent it to him, and he was willing and convinced.

The three points put forward by the first emperor basically include the effects of transport planes and bombers, and they are indeed worthy of being the first emperor of the ages, and this brain is turning fast, and as soon as he sees something, his thinking immediately spans two thousand years, and he has figured out the form of future warfare.

The most important thing is that this kind of spaceship is the only one of its kind in this era, and only Daqin has it, and no other country has it.

The First Emperor immediately ordered Yang Yifei to lead people to build all the remaining meteorites into spaceships, and after a year of construction, Daqin finally got 12 large spaceships of 20 zhang, 5 small spaceships of 10 zhang and 8 micro spaceships of 5 zhang.

Yang Yifei also modified the spacecraft and added movable sails, so that it is the same in the sky as on the water, and a lot of manpower can be saved when there is wind.

Of course, it is much more dangerous in the sky than on the water, so Yang Yifei attaches great importance to safety, and he has built the guardrail of the spaceship to a chest-high level, so that unless he can't jump the ship, it is difficult to fall down.

As long as the absolute stability of the meteorite is ensured, the chance of a plane crash is not great.

The second is the propeller, and he will regularly urge the "ground crew" to replace the propeller and gear to ensure that the ship is not affected by wear and tear.

With these 25 spaceships, Daqin's transportation efficiency really increased greatly, and after the First Emperor took a few large spaceships and experienced the thrill of flying, he rarely took them again.

After all, he is the emperor, although the reliability of this spaceship is very high, and the probability of an accident is very small, no matter how small it is, it is also risky.

Therefore, except for the occasional miniature spaceship and a banquet in the air closer to the ground, he rarely flies high on a large spaceship.

Eight years have passed in a blink of an eye, the world is still peaceful, and Daqin is getting better day by day, but this time after Yang Yifei's body came, he secretly did something.

A few months later, the farmers around Xianyang planted two new grains, which are not only soft and delicious, suitable for vegetables and grains, but also the most important thing is that the yield per mu can reach thousands of catties, and the names are sweet potatoes and potatoes.

This incident soon alarmed the household department, and the household department Shangshu personally led Si Nong to investigate, and found that the matter was indeed true.

When asked about the farmers who planted them, they all unanimously said that one night a few months ago, a mysterious man in black gave them sweet potatoes and potatoes and taught them how to grow them.

After the first emperor got the report of the household department and offered sweet potatoes to the first emperor to taste, he immediately issued an edict to find the person who offered these two kinds of food, but after several months, there was no result, but many swaggering people came.

When the court officials asked them where their seeds were obtained and under what circumstances, they could not explain why.

These people were naturally imprisoned, and finally Yang Yifei persuaded the first emperor to give up, since the other party did not want to show up, it must be a worldly master with the world in mind, so the first emperor gave up and withdrew the edict.

It's not that Yang Yifei doesn't want to get this great achievement, but he himself can't tell the source of the seeds, and besides, he is now the most noble person in Great Qin except for the First Emperor, and he is also the most trusted person of the First Emperor, even if he gets this credit, it is of no substantive use.

Subsequently, the First Emperor ordered the cultivation of potatoes and sweet potatoes throughout the country, and the grain of Daqin was more abundant and there was no longer the risk of famine.

After that, Yang Yifei took advantage of the night to fly to the city hundreds of miles away with his ability, and spread all kinds of other vegetables and grains, the food of Daqin became more and more abundant, the people became more and more wealthy, and the rivers and mountains of Daqin were naturally more stable.

After the 250-day break, Yang Yifei returned to the system space, he was looking forward to coming over next time, and he didn't know what earth-shaking changes he would see in Daqin.

He sincerely hoped that he could see the day when Daqin created the "Great Wall Railgun".
