Sun Jian was born as a melon farmer, much more unbearable than Liu Bei, Sun Jian and Sun Ce both generations started by attacking and killing court officials, and the original lord was still the number one rebel and thief Yuan Highway in the late Han Dynasty.

Therefore, Sun Quan is political foundation is not good, reputation is not good, he can't be a righteous person who helps the world at all, he can only be a warlord in troubled times, the territory is a little bigger, and the secession can be a few years, when the situation is critical, he is cheeky to Cao Cao or even Cao Pi to call his ministers, even if he calls Liu Bei "Your Majesty" it doesn't hurt at all.

And Liu Bei's ambition is by no means more than that, measured by the eyes of a warlord, he really looks down on him, Cao Cao Sun Quan can use the covenant and faithfulness as papyrus, but Liu Bei resolutely can't, because political reputation is the foundation of his struggle for half his life, and the foundation of the soldiers and generals can always fight against Cao Cao.

Think about the serious damage to Liu Bei's political reputation in the two steps of taking Yizhou and claiming to be the king in historical facts, Sun Quan easily attacked the three counties of Jingzhou, and tens of thousands of field elites were attacked by Lu Meng, and Guan Yu was awarded the head without a fight, you are Liu Zhang's first year, he is Guan Yu's fifteenth, and sooner or later he will have to pay it back, what is there to complain about?

Look at Cao Cao's rear has always been unstable, the uprisers have risen one after another, and the trouble of "coercing the princes of the Son of Heaven" is that his own subordinates and courtiers loyal to the Han court have not been clearly distinguished, and even Xun Lingjun, the number two person in the group, finally broke with it, not to mention anything else.

It can be said that many Han courtiers at that time, almost in a group of grass-headed kings in troubled times, faced with Liu Bei, who was the emperor of Yuanzhou, and the Sun warlord, who attacked and killed legitimate officials, had no choice but to reluctantly accept the final fact that Cao Wei was the Han dynasty.

If deduced according to this strategy, Liu Bei really held high the banner of recovering the Han Dynasty, successfully unified China, or at least collected the three states of Yongliangyi, and returned the capital to Chang'an, so as to achieve a three-legged stand in the true sense, no longer the six armies were mourned and cried blood White Emperor, leaving a state foundation to Kong Ming and ending up with hatred.

So even if the general trend of history is irresistible, one or two generations after him, the power is still usurped by the Shi clan gatekeeper, and the heroic deeds of his life are written in the history books and are worthy of the name of Emperor Zhaolie of the Han Dynasty, and can be worthy of the three ancestors of the Han Dynasty side by side with Gaozu Liu Yuan and Shizu Liu Xiu, rather than just being recorded in the official history in the name of "Shu Han Ancestor".

In history, Liu Bei died of illness in the White Emperor City, and Zhuge Liang realized the importance of this strategy after fully mastering the political situation of Shu and Han, so he devoted his efforts to Wu, gave up his territorial claims to Jingzhou, and also put aside the grudge that nearly 100,000 troops were defeated in Jingxiang and Yaoting, and even did not hesitate to recognize the legitimacy of Sun Quan's claim to be emperor to maintain the alliance with Wu, thus giving up the assumption of "crossing the two states and establishing the Northern Expedition" in Longzhong in the early years, and went north to fight for Yongliang.

It's a pity that at this time, the situation in the world has been decided, Cao Wei has been based on the world's Kyushu, two-thirds of the world, the Cao family has been operated for two generations, and the people's confidence in their own family has been basically determined.

Su Yu said the truth, Liu Yuan smiled, hugged Su Yu, and hummed and said, "With your ability, there will be nothing to do with Wu Cao in the Tang Dynasty, but well, it is now the Three Kingdoms, and you can always draw perfect conclusions from the perspective of God, historical figures should be analyzed in the historical environment, and now, it is time to use my strategy to go." ”

During this time, Liu Yuan was also accumulating strength, and Su Yu planned to directly copy the traditional traverser mode mode and upgrade the farming to fight the world.

The first is the production of chemical fertilizers, coal coking coal will produce a small amount of ammonia in the coking process, this is because the coal itself contains a certain amount of nitrogen-containing heterocycles, in the coking process these nitrogen elements will be released in the form of ammonia gas, mixed in the coke oven gas.

In fact, in the era when human beings did not make synthetic ammonia, this is the easiest way to get ammonia, as for the production equipment, this is actually not a problem, the soil method of coking is not difficult, as long as the coke is piled up, and then covered with soil, just light a fire.

Simple soil method coking device, in order to facilitate the collection of gas, may need to make a little modification to the way of coke accumulation, it is best to retain a gas outlet, in order to improve the efficiency of the best way or to make a coke oven, which can be done in ancient times, because there was a blast furnace in the Eastern Han Dynasty, and in the later period, in order to burn ceramics, the kiln technology is absolutely passable.

With ammonia, the next thing to do is to find an absorption medium, absorb the ammonia, and then make nitrogen fertilizer, the absorption medium is nothing more than acid, the common ones are sulfuric acid, hydrochloric acid and nitric acid.

Sulfuric acid is most convenient here, and the production of hydrochloric acid is more complicated, requiring electrolysis of salt water, and then it is necessary to make burners for hydrogen, chlorine and gas, which was more difficult in ancient times.

As for nitric acid, this is even more complicated, either by discharging the air at high pressure to obtain nitrogen oxides, or by oxidizing with ammonia, which is obviously very technically difficult. In summary, it is most convenient to use sulfuric acid for absorption.

The production method of sulfuric acid can use the lead chamber method, which is an ancient chemical production method, mainly using sulfur has been burned with saltpeter, sulfur combustion to produce sulfur dioxide, saltpeter combustion to produce nitrogen oxides, nitrogen oxides oxidize sulfur dioxide to form sulfur trioxide, and further obtain sulfuric acid.

Of course, there is a more ancient method in this time and space, that is, the minerals formed by sulfate are directly distilled, and concentrated sulfuric acid can also be obtained.

As for the container problem, this is also very simple, sulfuric acid is highly corrosive, and the iron pot must not work, but it is not possible to stand the development of ancient ceramic technology in our country, and the iron pot is not successful, and it is very easy to get a ceramic water tank.

After the dry distillation of green alum, concentrated sulfuric acid will be obtained, at this time, you need to mix some water into it to make it into dilute sulfuric acid, and then make a pipe, and pass the coking gas into this water tank, ammonia will be formed after contact with dilute sulfuric acid, and finally the solution of ammonium sulfate can be obtained.

In fact, a solution of ammonium sulfate can be used directly as fertilizer.

The next step is to improve the way crops are planted, the use of chemical fertilizers and pesticides to achieve a substantial increase in production, food is the primary problem to be solved by the traverser, to solve the problem of eating for the people, naturally can be supported, there is food in the hand of the heart is not panicked.

Only enough food can be supplied to a large number of craftsmen and even workers who have left agricultural production, in exchange for raw materials for production, to make bows and crossbows, armor, expand the territory, enough people to upgrade, small-scale production of firearms, and at the same time to start to establish a production line of daily necessities and decorations and luxury goods, and earn money through export trade, and part of the profits earned will be used to expand production, and part of the profits will be used to invest in education and train the younger generation with modern knowledge, so as to achieve a virtuous circle......

Su Yu was ambitious, wanted to replicate Yang Pingfan's successful experience, and also wanted to fulfill his dream of transforming the old world as a traverser, but he didn't expect to start only the first step and solve the food problem, and other work was stopped by Liu Yuan.

The members of the crossing team scattered in various places gathered in Wuchang because Cao Cao was here again.

During this time, Cao Cao solved the secession forces in Guanzhong, Guanxi and Yongliang, and was supplemented by the surrender forces of Zhang Lu in Hanzhong, and felt full of confidence, and re-raised an army of 400,000 to the south to confront Eastern Wu in the Huainan area.

Liu Yuan gave himself the title of Governor of Water and Land, Li Donglai was the left general, Guo Xiong was the right general, and led an army of 70,000 to the north to fight against Cao's army.

The two sides confronted each other across the river, and no one dared to challenge first, Li Donglai and Guo Xiong still had two brushes, and they brought a group of men and horses to a neat appearance, and they did not hesitate in the face of the black and oppressive Cao Jun.

After Liu Yuan took Eastern Wu, the two broke up the original Suzaku Army and the surrendered Wu Army, focusing on training their physical fitness, fighting and queue and other basic subjects of modern infantry, and at the same time paying close attention to battlefield discipline.

There is a shortage of horses in the southern water network, mainly the infantry army, and the infantry army in the era of cold weapons can only resist the cavalry charge by forming formations, Li Donglai followed Yang Pingfan in the Jin Dynasty, and he was experienced, he once boasted in front of Liu Yuan that he could build an eastern version of the Macedonian army, and the Cao army went south, which was a good time to test the results of training.

It's a pity that they won't have the opportunity to perform today.

The wind and waves on the wide river are calm, the breeze blows with the earthy smell and the dampness of the south of the Yangtze River, the weather is gradually cooling, the edamame leaves stretched on the shore have revealed the yellow color, the white wild chrysanthemum, a cluster of heads from the grass, and the small yellow flowers tremble in the cool autumn wind, deep in the forest, a lonely bird gently and timidly chirps, it feels that winter is coming, in the light mist, there is a whistling sound of apes in the distance, whimpering, as if from the depths of their hearts....

In the distance on the heart of the river, the two small boats are separated from each other by nearly ten zhang, and they are scolding each other with loud voices, which is a necessary program before the war in this era, called going out of the city to fight, but both sides can't figure out each other's strength, and the so-called provocation has become a daily program to greet each other's families.

Liu Yuan slowly descended from the sky to the camp alone, and the soldiers of Eastern Wu had long been surprised by the various behaviors of the immortals, and continued their own affairs, passing through the group to meet him, looking at him with their eyes, you must know that Liu Yuan is sitting in Wuchang to overview the logistics, and at this time, he suddenly came to the front line, there must be a big event.

Liu Yuan's eyes swept around, and he said with a big grin: "I have already arranged everything, ordered people to go down, build more rafts, and prepare to cross the river and the Northern Expedition." ”

Li Donglai was stunned for a moment, "What? What about Cao Cao's 400,000 army on the other side?"

Liu Yuan showed a smile that he thought was evil and crazy, and he didn't explain, and went straight away.

Everyone was confused, so they could only continue to blow the wind and fish by the river.

Guo Xiong squatted beside Su Yu and asked her if she could guess what arrangements the boss had made, Su Yu was also confused, he had a handful of thatch in his mouth, and said that according to the historical trajectory, Cao Cao and Sun Quan had been facing each other for more than a month, and they withdrew if they couldn't find the fighters.

"But why did the boss say that he was going to cross the river?"

Su Yu shook his head, "I don't know about this." ”

Guo Xiong couldn't ask for the reason, and was about to return to the camp, but suddenly felt that the twilight sky that had already fallen into twilight actually became bright again!!

He subconsciously turned his head, and then he was stunned to see a brilliant flash of light piercing the northern sky, and then, accompanied by the exclamations of the soldiers in the large camp, an extraordinary white light swept from the end of the distant horizon, so bright that people could not open their eyes.

The soldiers of Eastern Wu first saw that the earth was submerged in a strong light, and many of them had an ancient legend in their minds, which was volleyed in the sky for ten days.

The momentum of the light lasted for about fifteen seconds and vanished, as a loud bang sounded as if the earth was exploding beneath its feet.

The person who raised his head found that the originally dark sky turned blue, and the blue sky was in a circular area with the center of the explosion, which was rapidly expanding outward, and it was the shock wave of the nuclear explosion that dispersed the clouds, and later the other traversers knew that the clouds within a radius of 100 kilometers around the explosion were dispersed.

In the middle of this blue sky is a mushroom cloud that stands tall in the sky, and the mushroom cloud is initially divided into two parts, one part is two thousand meters in the air, and it is a large white ball of smoke wrapped in flames after the initial cooling of the fireball.

The other part on the ground is the dust stirred up by the shock wave, like a huge pyramid with a gentle slope.

The spire of the pyramid protruded a thin strand upwards, and finally joined it with a large white orb, which absorbed the dust from the pyramid, and the color immediately darkened, and the flames in it appeared in a part of the sphere from time to time.

By this time, the fog below had been dispersed along with the clouds, and the bold hand took away the hand covering his face, and he could clearly see the scene on the other side of the river, and the earth suddenly blurred, as if it had become liquid, into an endless flood, and those small hills were like islands and reefs in this flood.

More and more people took away their hands to cover their eyes and looked at the tall mushroom cloud in the sky across the river, which had now turned a deep black, and the afterglow of the sunset in the twilight had just shone on the top of the mushroom cloud, outlining a changing golden outline, and the large circle of clear blue sky around it was still slowly expanding......

Guo Xiong, the right general who was caught off guard, was naturally almost dazzled by the strong white light.

A moment later, another gust of wind with a scorching breath suddenly blew, causing him to stumble and fall straight to his stomach. When he finally regained his vision and raised his head again, he suddenly saw a bright and dazzling fireball, rising from the end of the horizon in the direction of Cao's army camp on the other side of the river, reflecting the entire world in the twilight extraordinarily——

Such a violent visual impact immediately caught everyone in the crossing group off guard and made them feel dizzy.

A thought arose in everyone's hearts: Oh my God, isn't this the mushroom cloud created after the explosion of the nuclear bomb? But how could it appear here? What did Liu Yuan do when it appeared in the Three Kingdoms era?

Liu Yuan appeared triumphantly in front of everyone again, and Li Donglai was the first to rush over and grab him by the collar, the corners of his mouth trembled, "You actually used a nuclear bomb on Cao Jun?"

"Let go, I won't use that kind of thing to kill a thousand enemies and damage eight hundred. ”

Liu Yuanyi pushed Li Donglai away and tidied up his crown clothes.

Li Donglai was unrelenting, "What is that, such a big mushroom cloud, what else can there be besides a nuclear bomb?"

"Who said that only nuclear bombs have mushroom clouds, don't worry, it's just an antimatter bomb for testing, no pollution and no radiation, which can be called a must-have product for traversers to kill people and destroy the city. ”

Li Donglai loosened Liu Yuan's collar, holding back a bunch of words in his heart, but he didn't know how to complain.

Antimatter is the anti-state of normal matter, electrons have a positive charge, protons have a negative charge, and when the positive and antimatter meet, the two sides will annihilate each other and cancel each other, an explosion occurs and a huge amount of energy is generated.

Although as early as September 18, 2000, CERN announced that they had successfully created about 50,000 low-energy antihydrogen atoms, but there is still a long way to go before the real macroscopic state of antimatter, no one expected Liu Yuan to come out and bring it to the Three Kingdoms without everyone knowing, and what's even worse is that-

Special meow actually used it directly without everyone's opinion.

Li Donglai put Liu Yuan's identity as the boss behind him, his eyes showed a fierce light, and he stared at Liu Yuan, "Why do you do this?"

"I'm tired of it,"

Liu Yuan shrugged his shoulders very meaninglessly, "I used to think that it was a very interesting thing to travel through the past and change my life against the sky, but when it was really my turn to do it, I realized what a troublesome thing it was."

This is by no means like three or five years can be successful, the end of the Eastern Han Dynasty is too poor, and it is impossible for me to spend more than ten or twenty years in this time and space to start from scratch and establish a modern industrial system, education system and civil service system, so I have to end this copy quickly.

We've changed the course of history, and in order not to have an impact on the base plane, we can only greatly distort history and create a parallel plane, so you know. ”

Li Donglai's lips trembled, "Then you shouldn't use nuclear ...... Antimatter weapons, so many lives...... "He is a soldier, and he is naturally resistant to this weapon of destruction.

"Generating parallel time and space, they are people from another world, not the ancestors of the baseline time and space, their birth, old age, sickness and death, just like the NPCs in the game, you shouldn't have feelings for them, you will be lost in history. ”

Li Donglai was speechless for a while, and he didn't know how to refute, so he could only leave sullenly.

The corners of Liu Yuan's mouth were slightly raised, but his heart was extremely uncomfortable, the tirade just now was actually just an excuse, the real reason was that he found that he couldn't control the overall situation.

After winning Dongwu and becoming the lord of the eighty-one counties in six states, Liu Yuan was also full of ambition and prepared to have an addiction to the world and the Central Plains.
