Chen Ke's question was very direct, and Xu Fu's answer was also very direct.

"Brought it back."

He looked directly at Chen Ke and replied, "I found several grain crops in the Yin Shang Continent that I didn't have in Great Qin."

"The yield of these food crops is very high, and the most important thing is that it does not conflict with the rice and millet that we are growing in Daqin today."

Chen Ke's eyes were shining.

He could guess what these two grains were, the seeds of grain that came from the Americas and produced a high yield, weren't they sweet potatoes and potatoes?

Although the yields of these two things are high, the conditions under which they are cultivated are relatively low.

It is very suitable for the current situation of Great Qin.

Although today's Daqin seems to be in good weather and there is no shortage of food, for those who really know the inside story, they are actually worried in their hearts.

The twelve granaries of Daqin are now unable to make ends meet.

At the beginning, in the first year of the First Emperor, the grain in the granary was decreasing, and the consumption was far greater than the harvest.

Later, after the unification of Great Qin and the gradual stabilization of the world, the output of grain increased a little.

But it's still beyond its means.

Later, Chen Ke came to Daqin, implemented a new field system, and exterminated the nobles of the Six Kingdoms who held a large amount of land in their hands.

There is a lot of land in the hands of the powerful people in these places, but not all of their fields are used to grow food.

There are even some fertile fields, which they use to keep pets, and they don't go to cultivate.

There is very little land in the hands of the Qianshou.

Chen Ke distributed some of this land to the head of Qian, and the other part was in the hands of the government, and then leased it to the people for planting, and Daqin's grain production increased.

If you use the numbers, the original expenditure is 7, and the income is 4, which is a difference of 30%.

Then after the new field policy, the expenditure is 7 and the income is 5.

Later, the last forces of resistance of the six countries were also exterminated, and the grain production was further increased.

Barely 6, or even 6.5, almost on par with spending.

Chen Ke looked at the two things that Xu Fu took out of his sleeve, wasn't the yellow one a potato, and the purple-red one a sweet potato?

He said with emotion: "With these two things, Daqin's grain output will soar in a short period of time." ”

Xu Fu looked at Chen Ke with some surprise: "Sir, do you know these two things?" ”

At this time, Chen Ke looked at Di Lun who was sitting on the side, and said with a slight smile: "I saw it from an ancient book that has been lost. ”

He smiled silently and said, "But King Yin should know more about these two kinds of food, right?" ”

"If I'm not mistaken, in addition to these two things, King Yin should have something to offer to His Majesty, right?"

Xu Fu listened to Chen Ke's words, and the look of surprise on his face became even more.

He looked at Chen Ke in disbelief, at this moment he felt that Chen Ke seemed to be a god, and he could see every move of himself and others from thousands of miles away.

"How do you know, sir?"

The surprise in Xu Fu's voice had overflowed, and Di Lun on the side was also looking at Chen Ke, and there was another layer of vigilance and reverence for Chen Ke in his heart.

Chen Ke and Da Qin were certainly not his enemies, nor were they Yin Shang's enemies.

But he came to seek the help of Great Qin, and he also wanted to become an ally of Great Qin.

What if Great Qin saw their external strength and directly destroyed them?

So, he had to be careful and careful.

A lonely person in Daqin, at this time, Di Lun felt a little sigh of drifting on the sea.

He said cautiously: "Xu Lingling has been saying that Governor Chen has a clever plan all the way, and now I see that it is true. ”

Di Lun said respectfully: "Actually, what we brought back is another kind of grain seeds. ”

"This grain can be grown in the mountains, and it does not affect the cultivation of other good seeds."

"And this grain can also be used as a staple food."

"Xiao Wang originally wanted to present it to His Majesty as a tribute gift, but he didn't expect to be seen through by Mr."

Chen Ke shook his head with a smile.

He didn't ask, just looked at Dillen and said, "Don't worry, I just read that book and know that you should still have a kind of food there." ”

"This thing should be presented to Your Majesty by you."

Chen Ke looked at Di Lun with a calm expression and gentle eyes.

But Di Lun felt that he was naked in front of Chen Ke at this time.

He was seen through by Chen Ke all over his body, including his careful thoughts and all the worries in his heart.

Dilen lowered his head, a hint of reverence in his voice.

"Thank you, Governor Chen."

Chen Ke looked at Di Lun's expression and smiled dumbly, he understood the worry in Di Lun's heart, and he knew that he could not alleviate this worry.

This is sometimes the case with state-to-state interactions.

Even if he came with good intentions, he would be wary and afraid, after all, not every country wants to be a vassal.

but

Let the Yin Shang of the Yin Shang Continent become the vassals of Great Qin, this is a thing that must be done.

No one can stop it, no one can stop it.

The resources on the Yin Shang Continent are too important, and they must occupy them in advance—or rather occupy the mineral exploitation rights there.

When all the silver and gold mines were mined there, it didn't matter if they were no longer used by them.

This is Chen Ke's plan.

At this time, Chen Ke just smiled gently: "Okay, King Yin, don't worry so much. ”

"You Yin Shang and Great Qin are originally from the Central Plains, the Zhou Dynasty is originally a fire virtue, and Qin is a water virtue, coincidentally, Yin is also a water virtue."

"You and I are from the same origin, and we will not do anything to you."

His expression was calm: "What you should know is that people in China are obsessed with their hometowns and will not leave their hometowns easily. ”

"If it weren't for the destruction of your country by the Zhou Dynasty, your ancestors wouldn't have traveled thousands of miles and migrated to the Yin Shang Continent with nine deaths, right?"

"Now that Great Qin is in the middle of the day in this Central Plains, dominating the world, how can he want to go overseas again?"

"Around Great Qin, there are countless lands that are close by."

"Ruling these lands is enough for Great Qin to bother, and Great Qin doesn't have that much ambition to rule all the continents."

"Those are not the wishes of His Majesty the First Emperor."

Chen Ke's words were sincere and reasonable, and Di Lun gradually relaxed after listening to it.

He felt that what Chen Ke said was very reasonable, if there was a choice, who would leave his hometown?

So, Di Lun said with a little shame: "Xiao Wang is ashamed. ”

Chen Kewan smiled: "Why bother? ”

He turned his head, looked at Fusu and said, "Fusu, you take King Yin to the dormitory where he rests." ”

"Xu Lingfang has just returned from overseas, and I chatted with him for a while, and also talked about the scenery and folk customs along the way."

Fusu immediately stood up and looked at Di Lun with a smile.

"King Yin, please come with this hall."

And Xu Fu on the side also understood what Chen Ke meant in an instant, and immediately said: "King Yin, this is the eldest son of Great Qin, His Royal Highness Fusu." ”

Emperor Lun's divine light flashed, this is the eldest son, the future crown prince, the future second emperor?

Immediately stood up enthusiastically and leaned over.

After these two people left, Xu Fu and Chen Ke's expressions became serious.

Chen Ke looked at Xu Fu and said, "Let's talk about the situation on the Yin Shang Continent." ”

Xu Fu immediately took out a small roll of paper from his sleeve, which had been hidden close to his body.

"Look, sir."

Chen Ke took the paper and listened to Xu Fu while reading it.

"Sir, after our people arrived at the Yin Shang Continent, they were divided into three teams according to your orders."

"One of the teams followed me to find the Shang Kingdom and help them defeat some of the other natives in the area."

"One of the other two teams went to find some food, some species, some plants, some animals that existed on the continent as a record."

"The other team is looking for all kinds of ores, as long as they have not seen them, and they are not stones, all of them are chiseled out in small pieces, and then they are marked on the map and brought back."

Xu Fu looked at the map that Chen Ke unfolded, and then glanced at the guards who followed him.

The guard understood it instantly, and then found the person who had been hiding outside, and got a bag.

"Whoa-la-"

A large number of strange stones fell in front of Chen Ke, all kinds of colors, messy.

"Sir, that's all the stone minerals we've found."

Speaking of this, Xu Fu said with some hesitation: "Our people have actually discovered another kind of resource, but it is not a stone mineral type. ”

"It's liquid."

There was a hint of fear in his face.

"This liquid is black and very viscous, and there was a person who accidentally landed a spark on it while exploring, and then it instantly burst into flames."

"There was only a small piece of that thing, and even if it burned, it didn't burn for too long, and it was extinguished."

Listening to Xu Fu's description, Chen Ke's mouth opened wide.

Black, liquid, burnable, viscous.

Isn't this oil the?

For a while, Chen Ke was a little dazed, he hadn't found oil from the Zhongqin Continent, so he first found oil from the Yinshang Continent?

In an instant, he even wanted to laugh.

If this is the case, then he has found two of the most widely used resources in this world before he returns.

Coal mines, oil.

When he has the most basic resources, maybe he can really consider starting the development of productivity.....

Of course, before doing this, the "foundation" must be laid.

Every excellent building, a towering high-rise building, must have an excellent foundation, otherwise the building will collapse before it is built.

Xu Fu looked at Chen Ke, who was thinking, and was a little uneasy: "Sir, but what's wrong with that kind of thing?" ”

He thought to himself, could it be that kind of resource was actually used by the immortals, and was accidentally discovered by himself?

Chen Ke, who came back to his senses, smiled and said, "It's nothing, it's just that I have seen that kind of resource in the book, and it is a very important thing." ”

He squinted his eyes: "I don't care what method you use, deceive, coerce and lure, you must let Di Lun take the initiative to ask the Great Qin garrison to be in the Yin Shang Continent before you arrive in Xianyang City." ”

"Let him know that Great Qin is interested in oil and minerals, and they can use these things in exchange for some of the things that Great Qin has as a reward."

Xu Fu was stunned for a moment, and then said solemnly in an instant: "Oh." ”

He knew that once Chen Ke said such a thing, then this thing must be very valuable, and it would even affect the entire Great Qin.

In the face of this kind of thing, Xu Fu knew in his heart that he had to get his hands on it!

As Chen Ke said, do whatever it takes!

After Xu Fu also left, Chen Ke was the only one left in the palace, he leaned on the table and pressed his forehead silently.

In his mind, he was constantly looking for the information he wanted, and those information was very hidden.

He's been looking for three or four days.

Outside the main hall, a sound of footsteps sounded quietly, and Fusu walked to the hall, his steps were light, and his expression was a little cautious.

He knew that his teacher had been thinking about "coinage" lately.

Nowadays, Daqin's coinage method is not satisfactory to the teacher, because the current method of forging "Qin Half Liang" is okay, but forging the "Qin coin" envisioned by the teacher is not good.

Qin coin is the general term for the kind of currency that the teacher envisioned.

"Whew."

Just when Fusu was bored, Chen Ke opened his eyes.

He thought of a good idea.

Technology that can be used in this era.

"Ceramic mold stacking method" and "mother money sand casting".

The former is simple, the latter is efficient, both are very simple and easy to use, and more importantly, the coins forged in this way are very durable.

The method of forging bronze coins is not too difficult, only slightly improved.

Forging silver coins requires modification of the material of the silver coin, silver is soft, and if it is forged into a silver coin, it can be easily broken.

This is not a good thing for Daqin, who wants to use this coin as the base currency.

Therefore, some "copper" juice should be added to the silver, and the two should be mixed together to forge the coin hard.

But another problem with this is that if more copper is added, the coin will become dark and black, and it is easy to be regarded as white copper by the folk leaders.

What's more, such a coin is not good-looking, and it is easy to affect the majesty of Great Qin.

Therefore, it became a new question to wonder how much silver should be and how much copper should be there.

Chen Ke can only find out from his memory, and the 925 silver in the later life is a pound of silver and thirteen coins of copper.

If there is more, it is easy to darken, and if there is less, it is easy to break.

However, the technology of refining silver in ancient times is different from that of modern times, and the content of silver in silver is not as pure as in modern times, so this is only a rough and model standard, and it needs to be considered by the craftsmen of the Manufacturing Department.

Chen Ke stood up and stretched silently.

It's August now, and the sunset is getting closer and closer.

If they want to return to Xianyang City before the twentieth day of the lunar month, then they must set off in October, otherwise it is easy to miss the sunset.

Therefore, there are still two months left for him to stay in Penglaizhou.

If Fuso's silver arrives before October, he will be ready to mint copper and silver coins.

Otherwise, he will only be able to set up a situation and wait until next year to deal with this matter.
