Playing intrigue is worse than engaging in infrastructure

Lian Ti looked at the person in front of him. In the night, his eyes were shining brightly, as if he could suck people's hearts and souls in.

He sat up and said softly, "Did your Highness think of something?"

Seeing his calm expression, Song Qingyuan gave a "tsk" and said, "You can grow tea trees there."

He had just carefully recalled the scene when he saw that valley.

At that time, there was a lower mountain between him and the valley, and the mountain was covered with dense jungle, so he couldn't see the situation below the mountain clearly.

But just looking at the vegetation at high altitudes should be a relatively humid monsoon climate.

Song Qingyuan is fairly familiar with the growth habits of tea trees. They like temperature and humidity, fear cold and waterlogging, like acid and alkali...the climate in the valley should be able to meet these conditions.

When he saw the valley for the first time, he also felt very magical.

Among the vast snowfields and glaciers, there is such a unique place with a mild climate, no severe cold in summer and no severe heat in winter.

He was only surprised at the time, but now that he thinks about it, it is simply the best choice for planting tea trees.

The only thing that made Song Qingyuan unsure was the high altitude.But after thinking about it, the Yigong tea farm in the previous life was close to 3000 meters above sea level, so it would not be a big problem to come here.

The more he thought about it, the more he felt that it was feasible, but Lian Ti raised a fatal question: "But there are high mountains and dangerous waters in that place. If you want to enter the valley, it may be very difficult."

Song Qingyuan took a deep breath and asked very puzzled: "Can't we open a way out?"

Song Qingyuan's doubts were so straightforward that he even froze for a moment, and began to wonder why he didn't build a mountain road in the first place.

But soon, Lian Ti reacted.It's not that they don't work hard at all, but that there are layers of mountains, and the difficulty of road construction is too great.

After explaining the difficulties to Song Qingyuan, the person opposite fell into deep thought.

After a long time, Song Qingyuan raised his head and said to Lian Ti: "Let me think about this matter first, there should be a way."

After speaking, Song Qingyuan bid farewell to Lian Ti and returned to his palace.

In fact, when Song Qingyuan mentioned the phrase "the cliff is steep and steep", he had a way to deal with it in his mind.

In later generations, opening up mountains and opening roads is simply a simple matter for people.

The reason why it is difficult now is nothing more than because the production level is still too backward.

Just imagine, using the most primitive tools such as shovels and sickles to excavate rocks, how can the efficiency be compared with various heavy machinery now, and the most important thing is that they still have gunpowder.

The method Song Qingyuan just said was the latter. It was too difficult to build an excavator, but it was not difficult for Song Qingyuan to make gunpowder.

Like the most basic black powder, it is nothing but potassium nitrate, sulfur, and charcoal mixed in a certain proportion.

These three things are not difficult to find now, even in the medicine cabinet in Zhou Qiao's medical center.

But Song Qingyuan paused the moment he blurted out.

He suddenly remembered that apart from being used to open mountains and roads, gunpowder is mainly used for war or to make guns and weapons.

That night, Song Qingyuan almost didn't sleep all night, thinking about whether the ratio of gunpowder he configured was good or bad.

But Song Qingyuan didn't think about this problem until the sun rose in the east and the light hit the bed curtain through the window.

In fact, there is no right or wrong gunpowder itself. It can be used to open mountains and build roads, it can also be used to fill guns, and it can even be used to make fireworks. It all depends on how the person who uses it chooses.

In the end, Song Qingyuan got up and told Jiang Duo to find these three ingredients.

He leaned against the window, watched the sky gradually brighten, and thought: The gunpowder used in mining is not the same as the gunpowder used in Chinese medicine. There is no need for him to think pessimistically that what gunpowder brings must be blood, tears and pain. .

Because he was thinking about Song Qingyuan's strange expression when he left Zhanxing Pavilion last night, he even mentioned that he came to his palace early this morning.

Seeing the person coming, Song Qingyuan smiled, waved at him and said, "Can your majesty help me find a place that is sparsely populated? Then send troops to garrison nearby to prevent anyone from approaching."

Lian Ti agreed without any hesitation.It is very difficult to find a place with a lot of people in Mobei, but there are more or less barren places that are inaccessible.

Just looking for such a place for what purpose?Lian Ti looked at Song Qingyuan with some doubts.

Song Qingyuan could see what was going on in his heart just from the expression on Lian Ti, raised his eyebrows and said: "Your Majesty will know later."

Taking advantage of the gap between preparing materials and looking for an open space, Song Qingyuan began to think about the ratio of gunpowder.

The best ratio of black powder is about 75% nitrate, 15% charcoal, and 10% sulfur, which is the ancient "one nitrate, two sulfur and three charcoal".

However, the gunpowder made with this ratio is used in firearms. If it is used for mountain blasting, then this ratio needs to be adjusted again.

Song Qingyuan remembered that he didn't know where he read it. If the proportion of sulfur was increased, the gunpowder produced would be more suitable for mining.

However, how much to increase specifically still needs to be known through experiments.

Jiang Duo has always been very efficient in handling affairs, but after a while, he brought the materials Song Qingyuan needed.

Lianti took them to a wasteland, and surrounded Lianti's pro-army outside to ensure that no irrelevant people would break in.

Song Qingyuan looked at the few soldiers who were sent to run errands for him, and said solemnly: "This thing is extremely lethal, and you may even lose your life if you are a little careless. Remember to do what I say. Don't be careless."

All the people present were soldiers who had been on the battlefield for many years. After hearing this, apart from being a little nervous, no one showed the slightest sign of fear or retreat.

The saltpeter and charcoal that Jiang Duo brought over were raw materials in chunks, and Song Qingyuan asked someone to grind them into powder first.

The saltpeter in this era still contains a lot of impurities, but Song Qingyuan didn't have time to consider the issue of purification.

If it is purified first, and then the ratio is tested, by the time the gunpowder is made to open up tea gardens, the day lily will probably be cold.

After grinding all the raw materials into powder, Song Qingyuan asked them to prepare a small amount of gunpowder with a total weight of not more than one tael according to the best ratio of black powder tested by later generations.

He didn't know how powerful the gunpowder was. If too much was mixed for the first time, after it was ignited later, not everyone would have to explain it here.

The prepared gunpowder is packed in a cloth bag, and a small opening is left at the top to pass through a long, grease-soaked cotton thread.

The person who installed the gunpowder lightly placed it in a crevice in the rock, quickly ignited the fuse, and then rushed back towards the crowd.

After a while, there was a loud noise from the rocks in the distance.

After the dust and smoke from the explosion dissipated, Song Qingyuan took a closer look, shook his head, and said to himself: "Sure enough, this ratio is a little less powerful than mountain opening, and it should be more suitable for propelling projectiles."

Different from Song Qingyuan's calmness, everyone behind him looked pale, and they couldn't hold back their breath even when they mentioned it.

With such power, even mountains and rocks can collapse, what if it explodes among the crowd?

For a moment, everyone's spine felt a little chilled.

Seeing that all the people present looked dull-eyed, Song Qingyuan shook his head, patted and raised the arms around his waist, stepped forward, and added [-]% of sulfur into it.

He was about to take the cloth bag containing the gunpowder and bury it under the rocks when Lianti hurriedly stopped him and said seriously, "Your Highness, don't do it yourself!"

Song Qingyuan was about to explain to him that this thing would not explode unless exposed to open flames or violent shocks, but when he raised his eyes, he saw that Lian Ti's amber eyes were full of worry.

He suddenly seemed to be scalded by Lian Ti's gaze, subconsciously lowered his head to avoid it, and silently handed the cloth bag to the soldier beside him.

The gunpowder with increased sulfur ratio was indeed several times more powerful than before. Song Qingyuan looked at the gravel and dust scattered on the ground and nodded with satisfaction.

"Do you all remember the proportion of gunpowder you just prepared?" Song Qingyuan looked at the people who first prepared the gunpowder.

Several people nodded slowly, obviously not recovering from the explosion just now.

It turns out that this thing is called gunpowder.Everyone thought.

"Is this the method His Highness said yesterday?" Lian Ti had regained his composure, and turned to look at Song Qingyuan.

Song Qingyuan nodded.Using explosives to open mountains and build roads can greatly reduce the speed of opening tea gardens.In this way, the tea trees should be planted before summer.

"This thing is called gunpowder?" Lian Ti turned his head and glanced at the rocks that had been blown to pieces, and said with half emotion, "It's so powerful."

Song Qingyuan replied absently.All his attention is now on the first explosion, even mentioning the subconscious movement of pulling himself into his arms, it was an obvious and protective movement.

And the worried look in his eyes just now made Song Qingyuan a little upset.

He remembers hearing the phrase, "A fire exposes what people hold most dear."

At the moment when the explosion sounded, Lian Ti's subconscious reaction was the most impossible to conceal.This also made Song Qingyuan have to face up to this feeling.

Ever since he got drunk that day and pierced the window paper between the two of them, Song Qingyuan was at a loss.

But after mentioning it, he behaved too naturally, no difference from when he was with himself before, so he ignored this question as if to avoid it.

When Lian Ti hugged him, the muscle lines on his arms tensed up.Even through the thick clothes of the two of them, Song Qingyuan could still clearly feel the warmth of his body.

He was a little confused, so he subconsciously looked into the distance and said, "If conditions permit, the power of gunpowder can be even greater."

After not hearing Lian Ti's response for a long time, Song Qingyuan asked eagerly, "Your Majesty, don't you believe it?"

Did Lian Ti discover his anomaly?

Song Qingyuan's throat rolled, and just as he was about to say something more, a voice with laughter came from his ear: "I certainly believe in Your Highness."

As for the difference between believing in yourself and believing that the power of gunpowder can be greater, Song Qingyuan ignored it because he was flustered.

He thought to himself, sulfur dioxide can be produced by burning sulfur, and sulfurous acid can be produced by passing it into water; sulfurous acid can be produced after sulfurous acid is oxidized, and nitric acid can be produced after sulfuric acid evaporates water to make concentrated sulfuric acid.

Nitric acid can be added to cotton to make smokeless gunpowder, and glycerin can be added to make TNT...

If he continues, he will be able to repeat the path that Nobel took.

Song Qingyuan didn't know the use of thinking about it now, but it seemed that only these emotionless chemical reactions could make him temporarily ignore the chaotic thoughts in his heart.

The author says:

Today's speech is a bit long, and it is an explanation of some of the content in the article.

The first is "one nitrate, two sulfur and three charcoal".There are mainly two different versions of this.One is that at this time, we have not mastered the proportion of gunpowder that can achieve an explosive effect.Because obviously, the amount of potassium nitrate in this recipe is too small.

而另一种说法则是这里的「一硝」是指一斤，而硫和木炭的单位都是两。古代一斤是16两，那16:2:3这个比例就非常接近后世的75%、10%、15%了。文中参照的就是第二种说法。

The second is specific knowledge about gunpowder. emmmmmmm...there is really very little information that can be found on the Internet, such as adding sulfur during mine blasting, this statement can be found, but I have not found the specific principle for a long time, so the authenticity is doubtful.

If there are any mistakes in the article, please forgive me, and welcome treasures who know it to tell me in the comment area.

Finally, "The fire will expose what people cherish most". This sentence comes from the British drama "Sherlock", which I also like very much.

And, thanks to the little angel who irrigates the nutrient solution: Miaoji. 45 bottles; 3 bottles of Nezhaye; thank you very much for your support, I will continue to work hard!
