When the Qin army was in the middle of the battle with the Five Nations Alliance outside Hangu Pass, Li Yunze was trying to grow new crops in a farmland outside Liyang City.

After these years of field investigation of Daqin, he has the most intuitive understanding of the agricultural production and needs of the people of Middle-earth in this era.

The most important thing is carbohydrates, which are commonly known as staple grains, and corn grown after years of cultivation and cultivation can already meet the demand with the blessing of water conservancy facilities and three fertilizers.

After all, the population of Daqin is only a few million, and with the combined efforts of water conservancy, three fertilizers, new farm tools, and cattle from the grassland, the corn produced is enough.

In Li Yunze's view, at this time, Daqin needed the most non-staple food and meat supplements.

Although it is said that outside the city in this era is a large swamp, a large forest, and full of wildlife.

But wild animals are not stupid, they will take the initiative to avoid the terrifying Homo erectus, and when they can't avoid it, they will choose to fight hard.

Not only is it very difficult to obtain, but the body carries many germs and parasites, which is very harmful.

On top of that, the meat is too chai and doesn't taste good.

Therefore, Li Yunze proposed to beat the nomadic tribes of the steppe, rob their pastures, and rob their cattle, sheep and horses to provide Daqin with a sufficient supply of meat, so as to improve physical fitness and average life expectancy.

Other than that, there is no side food left.

The so-called non-staple food is a broad term.

From chicken, duck, fish, fruits, vegetables, milk and eggs, and even seasonings, candies and so on, they can be called non-staple foods.

Li Yunze is also too lazy to collect seeds all over the world, and he has no time and energy to breed them from generation to generation.

Naturally, he brought the seeds directly from the modern world.

The first to appear is naturally the chili pepper, which is considered the favorite foreign seasoning of the Middle-earthers.

At this time, Li Yunze was squatting in this farmland full of peppers, wearing a straw hat, like a farmer carefully taking care of the crops in front of him.

"Actually, the king intended to let you lead your troops to Hangu Pass to fight against the Five Nations Alliance."

Li Si on the side, boredly, reached out and pinched a chili pepper and fiddled with it in his hand, "What a great opportunity, I don't understand what you think, you even refused such a good opportunity." Could it be that you can't fight? ”

Li Yunze, who was busy removing insects, responded without looking back, "I have fought more battles than you have ever heard of." For no reason, I'm just tired of it. ”

For this, Li Si naturally scoffed, thinking that Li Yunze was really capable of bragging~~~

What he didn't know was that what Li Yunze said was true.

If you want to talk about war, after so many worlds, you really have already fought enough.

And he has little interest in the princes fighting for the world or something.

As for fighting foreign enemies, whether it is the nomadic tribes in the north or the barbarians in the south, they are all like primitive societies, and most of the weapons used are still wooden sticks or something, so they are not interested at all.

These little Karami, it's enough for Yingzheng to deal with it.

Li Si is still chattering and complaining, "Those old Qin people are now becoming more and more domineering, not only grasping the military power and not letting go, but also meddling in political affairs and fighting each other everywhere."

Li Yunze, who was in addition to the insects, clapped his hands, picked up the basket from the ground and began to pick the red peppers.

When Li Si finished complaining, he said leisurely, "They like to fight, so let them fight." Anyway, it's the people of the Chu family who are fighting with them, what do you have to do with it? ”

"But if the Chu system is defeated, then it will be my turn to wait for these outsiders." Li Si said unwillingly: "Don't be at that time, those of us who have made great contributions have ended up being a lackey." ”

"Heh~~~"

Li Yunze, who had picked half a basket, got up and walked to another vegetable patch on the side, which was full of vitamin-rich carrots.

"The king is not a fool, how can he let the old Qin people control the military power and control the court. If that were the case, wouldn't the king have become a puppet, and the dethronement would be in the hands of others. ”

Li Yunze, who plucked the radish, comforted Li Si, "You just watch the old Qin people fight with the people of the Chu family, anyway, even if the Chu system collapses in the end, the king will support the new power." ”

Speaking of this, Li Yunze took a carrot and stuffed it into Li Si's hand, "You are now more and more reused by the king, and you will definitely be supported to ascend to the throne when the time comes." ”

Hearing this, Li Si, whose face was full of excitement, even twisted a little.

He actually understands what Li Yunze said, but he just wants to be affirmed and supported here.

It was only at this time that he expressed his true thoughts with a little twist, "If you can be reused by the king, you should do your best to assist the king." It's just."

Li Si's careful thinking, where can he hide Li Yunze's magic eyes.

Li Yunze, who has gone through the heavens and worlds, has tried with countless hearts and eyes.

After pulling out another half basket of carrots, Li Yunze walked to the house not far away, and then responded, "It's just that you are alone, I'm afraid it's difficult to fight against the old Qin people, right?" ”

"Exactly."

Li Si hurriedly followed, "Although there have been many people who have joined the sect recently, but there is nothing brilliant"

"You are a disciple of the Legalist family, or an apprentice of Xunzi." Li Yunze, who was walking forward, waved his hand without looking back, "Don't tell me, you are the only disciple under your teacher's disciple, and you are the only descendant of the entire Fa family!" ”

Liston paused, and a figure came to his mind, a classmate of his classmates and friends when he was a student.

When passing by the tomato field, Li Yunze also reached out and picked two tomatoes, "You happened to come here today, and I will make you a scrambled egg with tomatoes." ”

With the advancement of iron technology, things like iron pots will naturally appear under Li Yunze's suggestion.

With an iron pot, there is naturally stir-frying.

Because there is no shortage of livestock in Daqin at this time, there is also a lot of animal oil, and when stir-frying, there is enough oil, enough salt, and condiments or something, and the level of color and fragrance has jumped more than a step compared to before.

Li Simei ate a delicious meal, and was so addicted that he wanted to pack and take a few cars back to the mansion to enjoy.

"We'll talk about it in a few years."

Li Yunze chuckled and refused, "This is a breeding place, and when it is fully rolled out in a few years, and every household has the seeds, you can eat as much as you want." ”

When Li Si left, he still took half a cart of things, mainly seeds, and he said that he would go home and pull out all the flowers and plants in the garden and plant these good things.

Li Yunze didn't say much about this approach, because he knew very well that Li Si, who was gradually reused by Yingzheng, was no longer the Li Si who was worried about the cost of leaving the Qin State in the Zhaoxian Pavilion.

Speaking of which, Li Si himself understands the truth and things, and coming to him is just a temptation.

After all, as long as Li Yunze is willing to come forward, the candidate used by Yingzheng to balance the court must be Li Yunze, not him Li Si.

Li Yunze has seen too many of these scheming in the world of the heavens and all worlds, and he has long been accustomed to it.

Seeing Li Si's huge convoy gradually moving away, Li Yunze shook his head, put on a straw hat, and continued to go to the fields to do farm work.

In the following days, Li Yunze stayed in the countryside and did not go out in the craftsman's prison, except for the occasional visit by Ying Zheng and Zhao Ji, outsiders did not even know where this Taifu was.

Correspondingly, the Yan State meticulous workers squatted in the Taifu Mansion, and even arranged for people to enter the mansion, but there was no useful information.

Time flies, and in a blink of an eye, it has come to the eighth year of the reign of King Qin.

In this year, Zhao Ji officially handed over the Great Seal of Qin to Yingzheng, and the king finally completely controlled all the power of Qin.

It was also in this year that Ying Zheng came to the craftsman prison and saw the original version of the steam engine.

"The principle of the steam engine is actually to boil water."

Li Yunze dutifully fulfilled his duties as a taifu and taught Ying Zheng that "after boiling water, high-pressure steam will be generated, and the expansion force of this high-pressure steam will be used to promote the movement of the piston to obtain energy conversion." ”

As early as BC, there was a Greek mathematician Hero, who invented the most primitive prototype of the steam engine, which was called the air spinning ball, and its principle was basically the same as that of the steam engine.

Even the real steam engine was not an invention of Watt, the steam engine had already appeared before him, and had even been used in practical applications in mines and other places.

What Watt did was to make improvements and promote its popularization in industry.

Ying Zheng was stunned and looked at the big guy in front of him who kept whining, and his heart was agitated, "Such an artifact."

"I told you!"

Li Yunze immediately interrupted his words, "This is not the work of God, this is the power of science!" ”

"Yes."

Ying Zheng, who cleaned up his mind, immediately looked at Li Yunze with a straight face, "Thank you Taifu for your warning, it's the widow Meng Lang." This is what I have done as a scientist, and it is a practical application of mathematics, physics and chemistry. ”

Well, in Ying Zheng's view, all the schools of thought are useless, they are all rhetorical about the mind, that is like us scientists, talking about practical application, which can bring practical benefits.

Li Yunze nodded with satisfaction, "The son can be taught." ”

Li Yunze had already taught him about this, and even made some parts together, and Ying Zheng also knew the specific principles and compositions.

It's just that it's the first time I've seen a steel monster that can move on its own, and I'm a little distracted for a while.

"Taifu, what can I do with this thing?"

After being shocked, Ying Zheng asked for specific uses.

"There are many uses, but now, it's mainly used in the mining and transportation industries."

Li Yunze began to make on-site scientific explanations for Ying Zheng, which can improve production efficiency when used in the mine.

In this era, most of the mining was to mine surface minerals, and it was only after Daqin had gunpowder that it was mined.

Now with the steam engine, the natural efficiency will increase again.

Ying Zheng, who nodded again and again, quickly raised his doubts: "It is indeed good to increase production, but so much can be produced, where is it used?" ”

"The widow thinks that iron ore is indeed good, and can be used to smelt and make a large number of iron tools. You can dig up so much coal that you can't use it up. ”

There are many coal mines in Guanzhong, and some of the coal produced is used as coking coal for iron smelting, some as fertilizer, and some for heating.

It's still the old-fashioned coal stove briquette honeycomb coal or something, after having these cheap coals, the winter of the people of Qin is really much more comfortable.

Not only the Qin State, this kind of thing with little technical content, coupled with the large-scale popularization, the countries of the Kwantung region naturally learned it back, and quickly spread it in various countries.

"Coal is very useful, we have a lot of coal reserves in Middle-earth, and we should have started industrial innovation with all the barbarians."

Li Yunze shook his head and turned the topic back: "Coal can be used to drive these steam engines, and the calorific value conversion ratio is very high. ”

Ying Zheng looked at Li Yunze seriously, waiting for his next words.

"On the Western Regions, they have already hit Khotan." Li Yunze changed his words here and began to say that the Western Regions were over, "Khotan is thousands of miles from Xianyang City, and the traffic is very difficult. ”

"Exactly."

Ying Zheng immediately nodded in response, "It takes dozens of days to ride a horse, and if you walk on foot, it will take at least a year to make a trip." ”

"This steam engine can effectively solve this problem."

Li Yunze, who was smiling, stretched out his hand to signal the whining steam engine, "In front of it, Maxima will also be eclipsed!" ”
