ke it. What then”"Alas!"Liu Youcai sighed deeply.Liu Liang was stunned: "Dad, what do we do now""What else can we do Send people to learn! Whether or not it's profitable depends on luck. Let's learn f...Li Yiyiao and Liao Hongying, who were at the bandit camp, were also very excited when they learned that they had found the silver hidden by the bandits, and the amount was so large.

After carrying the twelve coffins back to the bandit camp, Yang Lin led his men to collect the remains of the two deceased and give them a proper burial. Only then did they hitch their horses to the carts and prepare to descend the mountain.

Thankfully, there are still four good horses on the mountain. Otherwise, with so much silver, we wouldn't be able to transport it back!

However, on the way down the mountain, Qin Shuang noticed something strange in the woods. She instinctively spoke up: "Lin Ge, look at that white line on the mountainside, it looks so weird."

Following Qin Shuang's direction, Yang Lin immediately saw the white line Qin Shuang had mentioned. He stopped and looked at it carefully for a long while.

Qin Shuang's "white line" wasn't a real line, but a white mark on the mountainside, like a white rope tied at the waist of the mountain, very conspicuous.

Yang Lin knew that from afar it looked like just a line, but in reality, it was a rocky outcrop on the mountainside!

Being able to appear so abruptly within the mountain, a layer of white rock... Yang Lin had already thought of a possibility...

"Come on, let's go check it out!"

Everyone was taken aback. They didn't expect Qin Shuang to simply say a word and then head over there

Qin Shuang was also a bit lost: "Brother Lin, I was just casually saying that. White lines are just white lines, it's probably just rocks. What's there to see"

Yet Yang Lin shook his head: "What if it's not an ordinary stone"

Everyone was confused, but they still followed Yang Lin and walked over.

As they came closer, the crowd could finally make out the "white line".

This is a layer of white crystalline rock reaching a thickness of two to three meters!

Yang Lin crouched down and picked up a finely forged iron arrow. He chipped off a small piece of it.

He first looked at it, sniffed it, and then tasted it.

After he tasted it and spat it out, his face was filled with delight!

"Well, is this another kind of useful stone" Li Yuyao asked curiously.

At the same time, she also picked up a small piece and looked at it from all angles, but no matter how she looked at it, she couldn't see what was different about this white crystal stone.

Yang Lin nodded. "Good, this is gunpowder!"

Li Yuxiang was taken aback and asked in confusion, "Herbs"

Though she didn't know what nitric acid was, she had heard of a kind of medicine called nitric acid.

However, Yang Lin shook his head and said: "What you said is saltpeter, saltpeter can be used as medicine, but this kind of stone, called fire saltpeter!"

"Fire powder" Liao Hongying asked curiously, "What can fire powder be used for"

Of course…

Firepower is of course used to make gunpowder!

But just as the words were about to leave his lips, Yang Lin stopped himself.

As the saying goes, one yellow rice flour, two yellow beans, three charcoal, add a bit of white sugar and Daiwan!

Making gunpowder is not complicated, but it's not as simple as "one sulfur, two charcoal, three potassium nitrate".

Yang Lin clearly remembered that the most reasonable ratio of potassium nitrate, sulfur, and carbon was 75% to 10% to 15%!

As long as you follow this ratio and experiment a few times, it's not a problem to create gunpowder!

When he first arrived in Dayan, he discovered pyrite and even yellow iron ore on the back mountain of a village called Koushan. The sulfur reserves were enormous!

Now that we've also discovered saltpeter, the material for making gunpowder, everything is in place!

However, gunpowder is a serious matter after all. If used well, it can change the world. So, how to make it and how to use it, one must still plan carefully.

It's not that Yang Lin doesn't trust the security detail, it's just that this matter is too important!

It's just like a bucket of plaster, worth ten taels of silver. The technical difficulty is extremely low; once people know how to make it, the price of plaster will collapse in an instant.

While gunpowder is far more important! And far more terrifying than plaster!

Yang Lin would absolutely never let the gunpowder formula leak out, not even a single ingredient!

"Of course it's used as fertilizer! This nitrate rock is rich in a substance called potassium nitrate, which is a very beneficial fertilizer for plant growth. As long as we process these rocks into powder and sprinkle them into the fields, even infertile land can become fertile farmland!" After Yang Lin's explanation, everyone was dumbfounded.

Stones can also be used as fertilizer, they are unheard of.

But Li Yuyao believed Yang Lin's words implicitly.

She just found it strange that Yang Lin knew all this. Especially the thing in gunpowder... potassium nitrate She had never even heard of it.

However, Li Yuxiang felt that things were not as simple as they seemed!

"This is a bit complicated to explain. Just hear me out when I get back!"

As she was deep in thought, she heard Yang Lin whisper to her softly from beside her.

Li Yuxiang's eyes lit up.

Indeed, there are more secrets to be uncovered!

And she started to look forward to it as well.

When Yang Lin and others returned to Koushan Village, it was already dusk.

The women who stayed at home, watching as large wooden chests were carried into the house, learned that so much silver had been brought back and were all astonished.

But they still told Yang Lin the good news about their home first.

Everyone is awake!

“Stay at home and take care of the injured younger sister,” said.

"Awake Great!"

Yang Lin is overjoyed.

The result looked like no one was home.

Si Mei hurriedly explained, "After they woke up, they were all taken back to their homes. Everyone knows our situation and that our home is already crowded. Now with so many injured people, it's inconvenient. They all said they couldn't add any more trouble for you."

Yang Lin sighed and nodded.

Whatever, it's good that the person is awake.

Have you told them about the wiretapping Yang Lin pressed.

"Well, I told them that when the wound starts to heal in a few days, come to our house to get the stitches removed," Si Me said.

Yang Lin also let out a sigh of relief.

He used ordinary cotton thread for sewing.

Even medical-grade suture cannot completely avoid rejection, let alone natural cotton thread.

So, it's crucial to remove the stitches as early as possible to avoid complications like rejection, infection, or inflammation later on!

"My husband, is all this really silver"

Wu Mei looked at the pile of boxes and asked in confusion.

The box was opened completely, revealing chest after chest of gleaming silver.

Even though they had seen a lot of silver before, they were still stunned at this moment.

After dinner, he began to count the silver.

It took a whole afternoon to finally count all these gold, silver and jewels.

Over 6,300 taels of silver!

Two hundred and twenty taels of gold!

In total, it's worth over 8,000 taels!

However, what Yang Lin didn't expect was that these weren't the most valuable things!

After seeing those jewelry, agate, pearls, jade, antiques, Li Yuyao confidently said: Those ancient jades and antiques together are worth at least over 10,000 taels of silver!

But that's not all.

What surprised Yang Lin the most was that among these treasure-filled wooden chests, he also found a dozen or so letters... laying the foundation this afternoon. I will finish the detailed drawings tonight and send them tomorrow."In the second phase, after relocating to the new design institute, the number of personnel at...
