I do research in ancient times

Feng Kang had a good idea, and the guard did hold his breath.

He had expectations for his eldest son, and Feng Kai did not disappoint him, and even grew faster than he expected.

But this time, with regard to the Liushan Iron Mine, the guardian really didn't want to understand.

He knew that his son liked Ning boy, so it was so easy to come back from the adventure, not only did he not go home, but he ate and lived in other people's homes, his intentions should not be too obvious.

Okay, I'll be a cub when I grow up, and I'm going out to build a nest and a shed by myself.But boy Ning is good, but he doesn't need to send mines to others!

I don't know what they are thinking about transferring my family property to others. I'm afraid it's not about stealing chickens or losing rice.

No, the stupid one is twelve, the boss is not stupid.

So Feng Daduhu couldn't figure it out.

The little bastard dared to speak like this, probably because he had made a decision in his heart.

In detail, the Liushan Mine was also dug by the little bastard. If the salt and iron were not related to the military situation, it would be difficult for him as a father to hold things in his hands.What's more, Mo Zong owns mines, and his family is not short of iron ore, so why make such a fuss?

That night, Chief Protector Feng didn't fall asleep, and spent the whole night thinking about the cub.

When it was dawn, there were also a pair of dark circles hanging on his face, and his spirit was slightly weak.

By the time Feng Kai walked into the study, Chief Guard Feng's depression was mostly discouraged, and the rest was just unreasonable doubts.

Why did the boss suddenly want to mine?

"Father, the mine is for the saltworks."

Feng Kai cut straight to the point, and directly solved the doubts of Chief Protector Feng.

He saw a small wooden box placed on his father's desk, Feng Dadu didn't know why, but he opened the lid anyway.

"This is……"

"It's salt."

Feng Kai said softly.

"Feidi helped Donghu build a salt field in Keteng Mountain, and this is the precious salt produced there."

Originally it was called Blood Salt, but the name was too sinister, so I simply changed it to Precious Salt.

The pink crystals are so magnificent that they look like precious stones, so the name of "treasure salt" is worthy of its name.

Hearing that it was salt, Chief Protector Feng didn't think much about it, he picked up a pinch and put it in his mouth, savoring it carefully.

"what?"

He raised his eyebrows.

The grains of this salt are fine, and the taste is pure salty, much purer than ordinary salt, almost without any miscellaneous taste.

"It's good salt."

Feng Dahu nodded.

"However, if you make salt for Donghu, you won't be afraid that it will be snatched by Xihu?"

Feng Kai shook his head.

"Of course there are concerns."

"However, the three tribes of the Donghu are now trapped in the Keten Mountains by the Xihu people. King Zuoguli has blocked the waterway on the Amur River. The Donghu cannot go to the sea to fetch seawater to refine brine. It will be a matter of time before they are trapped to death."

"At that time, Feidi and I were both in Donghu. If the salt shortage in Donghu could not be resolved, it would be almost impossible to return to the city. So Feidi built a salt field near the lake. It took about half a month to produce such Refined salt."

Hearing this, Chief Protector Feng didn't feel anything unusual.

Salt pans have existed since ancient times. Every family in the coastal towns set up pots to cook salt.

But what his son said next was completely beyond his cognition.

"Feidi found the brine lake in Keteng Mountain, but the three tribes of Donghu have ancestors' precepts that future generations should not burn the mountain to get firewood, and they should swear by the gods, so Feidi thought of a way to not burn firewood."

"What?"

Now, most of them couldn't calm down.

"You said the salt wasn't burned? How did that happen?"

So Feng Kai told his father about the construction process of the Blood Pond Salt Field, which made Du Hu amazed.

"Scary, there is such a strange method in the world?! Wouldn't it be possible to directly dry salt by enclosing a piece of land by the sea?"

Hearing what he said, Mr. Feng smiled slightly.

He knew that with his father's sensitivity, he would definitely be able to discover the doorway inside, and it was impossible not to be tempted.

"nature."

He nodded.

"The Donghu Salt Field is built by the lake, and all it produces is this kind of refined salt. The output is limited. Except for your own consumption, there is still a small amount that can be sold."

"If you want to circle the beach to dry salt, you can release the production as much as possible. I discussed with Feidi that Bailukou and Heyue's Tangzikou are separated by Heifeng Mountain. Unless Heyue's family detours from the sea, it is impossible to enter the coast. Bailukou is a suitable place for drying salt.”

"It doesn't matter if you are seen drying salt. Sun drying can't be achieved by drying salt alone. If you don't know the trick, it's useless to just learn the tricks."

Hearing what he said, Feng Dadu touched his chin.

"Then what if the old man He Yue took a boat to rob him?"

"It is to keep the use of the mountain mine."

Feng Kai slowly whetted his father's appetite.

"My brother Fei and I want to build ships, and we want to bring Donghu boatmen to Jiuling Lake. We also want to use the skills of Donghu boatmakers to build warships as soon as possible."

"However, it takes a lot of money to build a ship. Feidi estimates that it will take about ten years for the fleet to become successful. After all, this ship was built for my Feng family. Materials and labor are all consumed. My Feng family can't do nothing. The Liushan Iron Mine is just a waste of money. It's just a deposit."

He said it easily, but Chief Protector Feng's heart beat fast.

Warships, fleets, he thought about this thing when he was dreaming!Helplessly, the Feng family has no sailors, nor does it have a boat builder, so they can't keep the coast and can only worry about it, watching the two families in the Central Plains guarding the Haikou River and frantically amassing money.

The impoverished Duhu shed tears of jealousy countless times.

Now his son tells him that he can have a boat, and it can be a boat that can become a battle force in ten years. How can this not make him excited!

"Son."

Feng Bocheng wiped his face.

"Did you ask Ning boy, let's build a warship...how much money will it cost?"

"Feidi said, it depends on the size."

Feng Kai thought for a while and said a number.

"If it is made bigger, the cost will be even higher."

Hearing that, Da Duhu's heart went cold.

"Son."

Feng Bocheng swallowed.

"It seems that our family... can't afford that much money for a while."

Feng Kai nodded.

"My son knows, that's why we built the salt farm."

"Using the sun-dried salt method to make salt requires only a little firewood to purify the refined salt. If you don't pay attention to the quality, you can eat it just by drying it in the sun, which can greatly reduce the cost of purchasing salt for the frontier army, and sell it even more profiteering."

"It may be sustainable to maintain a ship with the benefit of the saltworks."

As he spoke, he took out a piece of paper from his pocket and spread it flat on the old man's desk, with a calm and calm tone.

"This is the salt principal estimated by Feidi, and the other side is the current salt price, please take a look."

Bah——!

After just one glance, the guard jumped up excitedly and knocked over the desk.

"Son! You didn't lie to me, did you! Kid Ning is really willing to help us build a field to dry salt?"

The impoverished Feng Dahu was used to careful calculations, and he was not usually sensitive to numerology, and he could see the huge profits contained in this piece of paper with just a glance.

Where is this fucking saltworks, this is simply a gold mine!It is still a big gold mine that can't be dug and spent, and it can produce as much as it wants, endless!

With this gold... Ah no, in the salt field, one Liushan Mine counts as a bird, and all ten of them will be given to Ning Xiaozi for fun!

But Feng Bosheng was battle-tested after all, he calmed down after being happy for a while, and soon thought of the shortcomings.

"We built a salt farm to make a lot of money. What if He Yue, who is a dog day, finds out that they send a boat to rob Bailukou?"

Feng Bosheng frowned and began to sort out his thoughts.

"Tangzikou is separated from Bailukou by a black wind mountain. It is not difficult for us to take down Bailukou, but it is not easy to prevent He Yue bastard."

"And the Lu family."

"The salt road has always been the ancient waterway of the Nanjiang River. The Lu family has earned wealth for several lifetimes on it. Our salt is good and cheap, so we must rob others of their wealth. That kid Lu Bei has a sea boat in his hand, and Good at water warfare, I'm afraid Bailukou will make a wedding dress for someone before our boat is built."

Hearing what he said, Feng Kai actually nodded his head.

"Looking at the current situation, the Lu family and He Yue's family cannot be defended. Once the sun salt market opens, the two families will definitely come to snatch it."

"I know!"

Feng Bosheng slapped off another corner of the desk that he had just lifted up.

"You son of a bitch, you don't need to say such frustrating words to me. You must have a plan, right? If you have a fart, you should let it go!"

Feng Kai raised his eyes and spoke softly and calmly.

"It's still the same sentence, that's why I want to keep the mountain mine."

"The minerals in the Liushan Mine are pure and suitable for forging weapons. Before our fleet has formed combat power, we can only rely on coastal defense weapons to protect the salt fields."

"This kind of weapon requires a lot of iron and stone, and the Liushan Mine is enough to last for ten years."

He walked to the window, took the cold tea soup from the low table, dipped his finger in it, and then drew something on the desk.

"It's this thing, it's called shore cannon. Inject special powder into the iron ball, put it into the gun chamber with fire powder and ignite the fuze, and the fire powder will push the iron ball out of the gun chamber, hit the ship at sea, and kill it Sink."

The idea of ​​the shore artillery was proposed by Ning Fei. In order to solve the defense problem of the coastal saltworks, the shore artillery is the only weapon that can be relied on under the condition that there are no sea ships to fight against.

The inspiration comes from some gunpowder cans thrown by the crossbow of the sailing boat when riding the tide at Bailukou. In fact, they are already considered miniature shells, and the lethality is beyond Ning Fei's estimate.

Now that there are shells, why not build artillery?

Mozong has a blast furnace for iron smelting, which can directly produce molten iron. Sand casting has been popularized in Modao casting. The proportion of gunpowder is ready-made, and all technical conditions are met.

The Bailukou Salt Field is not only important to the Feng family, but also to him, Ning Fei.The Feng family guarded Bailukou, and the river section from Bailukou to Jiuling Lake was safe. Not only could the big boats of Mo Zong and Donghu come in and out freely, but he also didn't have to worry about one day his identity would be exposed, and Lu Bei's fleet would directly enter Wuzhi. river pier.

Kill two birds with one stone, a win-win business, both foxes and wolves with big tails like it.

"That's it."

After Feng Kai finished speaking, his slender fingers slowly wiped away the tea stains on the desk, and also wiped away his father's reluctance and drooling saliva.

"Father, how is it?"

Young Master Feng smiled meaningfully.

"Can we do this business?"
