[Southern Song Dynasty] Splendid mountains and rivers

Autumn rain began to patter in the sky.

The autumn harvest has passed, and there are only crops of rhizomes left on the ridges.It has become a habit for the Jin people to run horses in the fields, and now few people go back to criticize them-after all, even the Liao Kingdom has been destroyed, what can they say?

This is the saddest thing.

The sixteen prefectures of Yanyun have been ceded for too long, and the people who have lived in Yandi for a long time have become accustomed to being Liao people.At the beginning, Tong Guan was eager to "recommend" him, but he just left in a disheveled state.It wasn't until the golden cavalry swept the Liao Kingdom and went south to attack the Song Dynasty that people in Yandi gradually heard about the fertile soil and water in the south.

However, today's rain is a bit unusual.

The garrison guards who were used to drills and horse races in the countryside were the first to notice something was wrong.No matter Jin people or Khitan people, there is a kind of vigilance of wild beasts in their bones.There was a pungent smell in the air, and the raindrops fell on the iron armor, and white smoke rose from it.The crotch. The armored horse even began to neigh to the sky, completely uncontrollable.

This is not right.

The vanguard and scouts in the army squinted their eyes and looked out through the rain curtain. There seemed to be a strange army not far away.They wear rhinoceros armor, felt hats and red tassels...

Song Jun! ?

What a ghost, how could Song Jun appear on this vast white land for thousands of miles!Still wearing rhino armor!

As we all know, armor is an extremely terrible thing.When the two armies are at war, whose armor is harder can withstand more swords and guns and reduce casualties a few times.Thin and tough rhinoceros armor is synonymous with courting death on the battlefield.

Gradually people found something was wrong.

The sergeants who came back from the drill stomped their feet and scolded their mothers, their armor already had ugly iron bumps.The carefully selected war horses in the Northland were whistling whitely, and almost died without rolling their eyes.Everyone said that the rain was weird, maybe it was the God of Sirius who graciously helped the Liao people to restore their country.

——It’s really his mother’s country!Even Emperor Tianzuo was forced to hide in Tibet, how capable the Liao people thought they were!

Both the golden soldiers and the golden generals stomped their feet and cursed, and the scouts were dispatched wave after wave.Some people said that they saw a strange white mist on the big river, and there was a fairy ship vaguely in the mist; some people said that all the Song soldiers in rhinoceros armor covered their mouths and noses, and started to light fire near the garrison camp.As long as people find it, they will run away immediately, faster than rabbits; some people say that the smell is a bit like realgar, and they are drowned in realgar wine the next day.

Really, hell!

Damn it!

The top general of the Kingdom of Jin, who was in charge of staying in Zhuozhou, went out in person. Before he left the city gate, he saw a letter shot from the opposite side, and almost shot him in the eye.Jin Jiang resisted the urge to scold his mother and took down the letter, only to find that his mother's letter was actually a letter of war!

This is not only a letter of war, but also a letter of war written by the people of Song Dynasty!

It's really his mother who met a ghost!

General Jin couldn't remember how many times this was the first time he scolded his mother today, so he immediately returned to the city after grabbing the letter, and called an emergency military meeting.A group of people discussed for a long time and decided to fight.

But on the second day of the battle, I saw a ghost.

Although the rain was still lingering, the pungent smell in the air was even worse.The raindrops splashed on the skin, and even some small red spots and red marks appeared.Song Jun on the opposite side had already wrapped his whole body tightly with rhinoceros armor, not even pulling off his fingers.Immediately afterwards, after they waved their knives in this direction twice mockingly, the soles of their feet immediately smeared with oil.

Do you want to fight or not!

Do you dare to fight!

Jin was so angry that he jumped up and down again and again, only to find that the armor on his body had corroded more severely in the raindrops.If this continues, the people of Song may not even have to wield a knife, just kick up and smash the entire armor.

This is a very serious matter.

Although the rain lasted for only two or three days, all the generals of the Kingdom of Jin stationed in Zhuozhou felt a chill, a chill that rushed from the soles of their feet to the top of their heads.

They decided to borrow troops.

The sixteen prefectures of Yanyun are connected together, and Zhuozhou is just in the southeast.And the closest to Zhuozhou is Yanzhou.

So they decisively borrowed troops from Yanzhou.

But the terrible thing is that this year Jin Guo repeatedly ran into ghosts, and the soldiers and horses from Yanzhou came, and the armor was still corroded to nothing.What's more terrible is that the soil has begun to clump, and some experienced farmers can tell that this land will soon be unusable for planting.

Natural disasters, absolutely natural disasters!

No matter how many people cried for their father and mother, the rain basically never stopped.The weirdest thing is that the range of the rain was neither big nor small, just near the state capital.As for the small towns and small villages in the lower reaches of Zhuozhou, there is no place where the Jin soldiers are stationed, and there is no smell at all.

After about half a month, Jin Ren received another letter full of irony: surrender or not?

------------

Zhao Yuan has been very busy recently.

The cold snap from Siberia should sweep across this land in two months.If there is no way to win Zhuozhou by then, then the acid rain must stop.If it doesn't stop, the Siberian cold current will bring the rain to the south, and the gain will definitely outweigh the loss.She has been wondering how much time the Jinren have left, and how much time they have to spend with her.

It is gratifying that wherever the acid rain falls, the golden man will retreat.Now most of Zhuozhou has become a thing in the bag, and the Zhuozhou defenders are retreating to Yanzhou step by step, and they are almost defeated.

As for how this rain was made...

S+O2=SO2

SO2 + H2O = H2SO3

2H2SO3+O2=2H2SO4

The three chemical equations in high school textbooks are enough.

——However, this method is too disastrous for the country and the people, children must not learn it.

In the end, Jin Bing submitted a letter of surrender.

Zhao Yuan immediately stopped producing acid rain and began to order the fields to be burned.

——She deliberately waited until after the autumn harvest, just for this day.

All that remains of the fields are harvested stalks, barnyardgrass, and other things.At this time, it is just right to burn the field.

Alkaline plant ash can neutralize the acidity of sulfuric acid and restore the pH of the soil to normal.In places where acid rain is severe, she even ordered quicklime to be sprinkled directly.Although calcium sulfate is also not a good thing, it is much better than soil polluted by sulfuric acid.

Song Jun, who had long regarded Zhao Yuan as a god, naturally had nothing to say. The only one who had a bitter face in front of Zhao Yuan was Zhang Bangchang, Mr. Zhang:

"Wow, Diji, they will backtrack on their promises—"

"I know."

"I have dealt with Jin people a lot before, and they didn't 'keep their word' at all...you know!?"

"I know." Zhao Yuan looked at the sky worriedly, "You can't be a sinner of history, can you?" If the whole land was destroyed by acid rain, later historians might poke her in the back and scold her. .

As for the gold soldier...

"I thought of a better way, do you want to try it?"
