The Qin Dynasty opened the Hengqu Four Sentences, sweeping away all the schools of thought

It is human nature to like beautiful things, such as good wine, delicious food, and beautiful women.

The Analects of Confucius also said, "Food, sex, and love are the greatest desires of human beings."

After tasting fine wine and admiring beautiful women at Changping Jun's mansion, Su Xuan returned to the Violet Chamber of Commerce and started to taste delicious food with Ying Zheng.

Ying Zheng had arrived early and waited in the private room for a while. Su Xuan naturally would not neglect him and had someone serve him good wine and food so that they could enjoy it together.

Freshly cooked delicacies were placed on the table. The rich aroma almost hit you in the face, and the attractive golden color made you want to eat more.

Ying Zheng looked at the steaming boiler, which contained mutton and a kind of food he had never seen before, a bright yellow, diamond-shaped block of something.

"Your Majesty may wish to try it." Su Xuan smiled slightly, and without caring about any etiquette, he picked up the chopsticks and started to taste it.

Seeing Su Xuan eating with relish, Ying Zheng couldn't help swallowing his saliva, picked up a piece and put it in his mouth, then his eyes lit up, it was so soft and delicious, tender and juicy, with a light spicy and fresh fragrance mixed with the rich soup, the aroma of mutton and the softness of potatoes blended perfectly, making it irresistible.

He ate with relish, and even after he was full, he still felt a little unsatisfied.

"Sir, what is this?" Ying Zheng asked curiously.

"Your Majesty, this thing is called potato." Su Xuan asked with a smile, "What do you think of this thing?"

"What a rare delicacy." Ying Zheng exclaimed in admiration.

"If this thing can produce 1,000 catties per mu, and if it is good farmland, it can produce 2,000 to 3,000 catties per mu, what do you think the value of this thing is?"

Three thousand kilograms per mu?

Ying Zheng's eyes widened in shock. How could the production of this thing be so high?

What followed was ecstasy. He looked excited and asked, "Are you serious, sir?"

"I have tried growing it in Xiaoshengxian Manor, and it is true." Su Xuan said with certainty. He had been learning skills in Xiaoshengxian Manor for four years and signed in on the system every six months. Apart from martial arts skills and elixirs, the rest were these miscellaneous things.

Potatoes appeared in the second year he signed in, and he did reclaim an acre of land to conduct a small experiment.

"Great! May God bless our Great Qin!" Ying Zheng laughed and then asked where this thing came from.

Seeing that they had finally reached the critical link, Su Xuan began to take it seriously, "This thing came from outside Kyushu."

"Outside the Nine Provinces, there are fertile lands stretching for thousands of miles, with natural resources and treasures, all-encompassing, dazzling, fertile fields, and fertile lands." Su Xuan exaggerated as much as he could, "On the coast of the East China Sea, there is an island country thousands of miles away, and it is covered with mountains of gold and silver."

"If Your Majesty only wants to conquer the six kingdoms, then this is enough for now. But if Your Majesty wants to conquer the world, then you need to build strong ships and powerful weapons as soon as possible."

Tens of thousands of miles of fertile land?

Ying Zheng couldn't help but imagine a picture in his mind. It turned out that conquering the six kingdoms was just to stay in a corner?

Is this world so big?

Without any hesitation, the first thing he thought of was to conquer these places.

If it is not conquered, then thousands of years later, wouldn't there be endless fighting like in the Warring States Period?

And if the world is really that big, how many scripts and languages ​​would there be?

Differences in cultural beliefs and disputes over national interests will inevitably lead to war!

Instead of this, it would be better to let the Qin Dynasty unify the world.

There is only one country, only one language, and everyone can live together in harmony. That is the supreme paradise that Ying Zheng wants to create!

As for whether he could accomplish it in his lifetime, he didn't care. His ancestors had fought for six generations and made Qin a strong country that unified the six kingdoms. If he couldn't unify the world, then his descendants would do it. If six generations didn't work, then ten generations would do it! A hundred generations!

To accomplish all this, we must have a more perfect system!

Thinking of this, he turned his gaze to Su Xuan, "Sir, conquering the world is what I must do. If you have any good ideas, please speak up. I will definitely support you."

Su Xuan said calmly, "If you want to cross the ocean, the ship must be sturdy and reliable. Your Majesty can call together skilled craftsmen who are good at shipbuilding, brainstorm, and reward those who contribute with a large sum of money."

"In addition, I have heard that Gongshu Clan's mechanical skills are extremely ingenious, and the head of Gongshu Clan is even better than his master. His mechanical skills are as exquisite as those of his master Lu Ban. Your Majesty can hand this matter over to Gongshu Chou."

"Let's leave this matter to you, sir. I will order Gongshu Chou to come to you and follow your orders." Ying Zheng waved his hand and handed it over to Su Xuan. "As for the money you need, you can go directly to Zhisu Neishi to withdraw it. I will inform him in advance."

Su Xuan agreed. If Gongshu Chou followed him, he could tell him some shipbuilding principles of later generations, which should be of great help to the progress of shipbuilding.

Moreover, this old man has superb skills in mechanical engineering. He can create things like mechanical snakes and Potu Shichiro without the need for energy. If there is an engine in the future, Su Xuan will definitely let this old man build a Gundam for him.

Mecha is the eternal romance of men!

The thought of flying through the sky in a mecha is fascinating.

At this time, Ying Zheng discovered his previous blind spot and asked, "Sir, you said before that the world is round, doesn't it mean that the world is round?"

During the Warring States Period, there was a common view that the sky was like a pot lid, covering the flat earth. Later, this view was gradually overturned, and the cosmological view of the round sky and square earth became popular.

In the "Circular Way Chapter" of Lüshi Chunqiu, there is a saying that the way of heaven is round, and the way of earth is square. This includes the Qin Dynasty's half-liang coin, which is round and has a square hole, and also contains the principle of the round sky and square earth.

When Su Xuan heard Ying Zheng ask this question, he felt a bit of a headache. It was a well-known fact in later generations that the earth was round, but in the present time, without the foundation of physics, his explanation would be like talking to a cow.

He understood it, but Ying Zheng didn't.

Since it was difficult to explain, Su Xuan simply let Ying Zheng see it with his own eyes.

He brought Ying Zheng to the courtyard, and he pretended to take the astronomical telescope, but actually kept it in his storage space.

"What is this?" Ying Zheng looked at the astronomical telescope curiously.

"This is an enhanced version of a magnifying glass, an astronomical telescope." Su Xuan's words were concise and insightful.

Under Su Xuan's guidance, Ying Zheng quickly figured out how to use it. He looked through the astronomical telescope at the stars in the sky. The vastness of the universe gave him an inexplicable sense of shock.

The stars in the sky were so clearly visible that he could even clearly see the surface of the moon, which was bare, uninhabited and desolate.

He looked at the Betelgeuse, Aquarius, and the Big Dipper one by one, immersed in them.

Su Xuan also looked up at the boundless starry sky. In fact, there was something he had always kept hidden in his heart.

The exploration of the earth was almost complete in the previous life.

Their journey is to the sea of ​​stars!
