I do research in ancient times

Ning Fei's idea is very simple. The main investment in the early stage is the hydraulic equipment and the first batch of raw materials. After the oil workshop is in operation, the raw materials and finished products can be exchanged for operation.

Yes, in order to expand the influence of technological achievements, Ning Fei is going to use the barter model to promote vegetable oil.The price of beans is low and the price of oil is expensive. If the two are replaced, it is definitely much more popular than simply relying on money to buy.

What's more, the world is already in chaos. In a chaotic world, materials are king, and money is scrap copper and rotten iron. It is better to use resource rotation to feel at ease.

What's more, borrowing the power of the river water to extract oil can greatly reduce the cost of oil extraction, and bartering should also be profitable.

Feng Kai naturally had no objection to his idea.

For Yu Feng's family, it is a great thing to have a property to house disabled soldiers and prevent meritorious people from being displaced.According to the current system of the imperial court, if disabled soldiers can no longer go to the battlefield, they can only take the money issued by the imperial court to go home and fend for themselves.

However, Fujin was held in the hands of the officials of the aristocratic family, and there was not much left after the layers were peeled off in the hands of the soldiers.Most of those who could not go to war had serious physical disabilities, and it was not easy to go home to fend for themselves.

Basically, it was left to its own devices.

The frontier army has been fighting Hu Qi for many years, and there are many disabled soldiers. In addition to the imperial court's compensation, the Feng family will subsidize some money from their own pockets, and this money is often the most that the soldiers can get.

But the money is always running out one day, some are seriously injured, and they will not be able to bring their family far away, so they quietly leave home by themselves and take the old road of Mo Zong to go up the mountain.

There is an old saying in the army, "It is better to die in battle than to be disabled." If you die in battle, you can get a lot of money, and the old mother, wife and children in the family can live better.If you are disabled, not only will you have less money, but it will also increase the burden on your family, which is not worth it.

It's not that Chief Protector Feng is ignorant of these things.

In fact, several generations of the Feng family have tried their best to solve it.From the old guard to Feng Bosheng, the men of every household are subsidizing the soldiers under them.But their power is limited after all, and they are not like aristocratic families who can extort money and accumulate riches and wealth. Most of the money to protect themselves is owed by the court, and they spend money like water, which is an out-and-out moonlight.

If this hydraulic oil press can really be successful, it can solve the big problem of the frontier army, and it can directly increase the prestige of the Feng family to the highest level.

In the future, when the frontier army joins the army, they can make meritorious deeds by fighting the enemy bravely, and there will be a way out if they are loyal to the country. How can anyone be afraid of fighting?

"Okay! Great! That's it!"

Feng Dadu slapped his hands, and walked around the study room three times excitedly, smiling so hard that his teeth could not see his eyes.

"Okay, okay! When will it be built? How much money will it cost, you old man and I..."

He just wanted to say "Your father, I'll take care of it", but the words stopped suddenly, and Dadu touched his withered purse, feeling a sudden sense of sadness in his heart.

By the way, now that the imperial court is falling apart, and the financial power of the central government is falling apart, most of the guards have not received their salary for more than half a year, and they are so poor that their sons even need to subsidize the money for drinking.

Da Duhu felt his face was dull and touched his nose.

"Damn it! I want me to run fast, but I don't want to eat grass for me. I'm fucking the three dog kings!"

After scolding, he still felt uneasy, so he picked up a piece of cloth on the table, tore the rags twice, threw them on the ground and stomped his feet twice.

"Look, it's just this Xihe King, who pretends to be orthodox, and wants me to send troops to seek rebellion for him."

"Why the fuck do I get involved in their shit?! Did someone give me a ration and a knife for the frontier army? Throwing a piece of rag is like letting the frontier army do their best. Who cares about the Hu army in the north? Don't want so many cities in the frontier?!"

"Damn it, you have the guts to wipe out the barbarians first, what kind of ability is there in the nest?!"

Having said that, he stopped abruptly, his brows locked.

"I heard the wind, saying that there was movement at Bailukou, is it true or not?"

"is true."

Standing in his father's study, Mr. Feng's expression was calm, even a little laid-back.

"The Yesaha sailors at Bailukou have changed recently, probably because they saw Fei and I sailing when we returned to the city, and wanted to learn from us and go upstream against the current."

"The spies sent back the news that Yesaha mobilized new paddle boats and dispatched two teams of sailors. In the past two days, taking advantage of the high tide at the mouth of the egret, we can reach the Black Wind Beach."

"What?! Arrived at Wufeng Beach!"

Feng Dahu slapped his hands.

"These bastards are quite strong, they can rush up to Wufeng Beach in one breath..."

"Passing the Black Wind Beach is Duanhun Cliff. The waterway here is so fast that boats cannot sail, but once you get here, there are no barriers to go up the river. You can go all the way to Jiuling Lake."

"We don't have a boat now, if the bastards touch it, our hometown will be taken away!"

Having said that, he suddenly stopped and looked at his eldest son suspiciously.

"You kid is so calm, do you have some bad water prepared?"

Hearing what his father said, Mr. Feng raised his eyebrows slightly.

He could be considered to have found the root cause of Twelve Lang's inability to speak, and it was also a skill for his father to be able to speak such ugly words of praise.

"Father forgot, I have shore cannons."

Well!

Feng Dahu was taken aback.

"Have our cannons been installed on Broken Soul Cliff?"

Feng Kai shook his head.

"It's not Broken Soul Cliff, but it's already at Heifeng Beach."

"The Xiaoqi Battalion of the Black Armor Army has deployed defenses at Heifeng Beach. The checkpoints spotted two fast-oared warships of the Xihu people in the middle of the night yesterday. However, because they were going upstream against the current, the sailors seemed to be very tired. We must find a place to rest."

Speaking of this, Feng Kai paused, and reached out his hand to point at the topographic map of Yongxi Pass on the wall.

"I think it can only be in Yazicao. There is a shoal here, and the big ship will not be washed away when it anchors, and it is just in the middle of Heifeng Beach and Duanhun Cliff, so it must stay here."

"I have deployed ten coastal defense guns here, both on the top of the mountain and on the half-cliff, distributed on both sides of the river valley, condescending enough."

"Ten gates!"

Feng Da Duhu slapped the table, grinning in distress.

"Why do you put so much?! Boy Ning only gave a few doors...that's all treasures!"

At this point, Feng Dahu paused and muttered softly.

"It's good to put it on the ridge. I think the cannon is very good at guarding the pass. It's accurate to hit Hu Qi."

Feng Kai's face was darkened.

Coastal defense guns are stationary and useless once out of range.In particular, Hu Qi is good at riding and shooting, and has excellent equestrian skills. He can ride his horse to avoid the range of shore artillery.He discussed it with Brother Fei, and they both felt that the coastal defense artillery was not effective against this kind of mobile warfare.

My father just watched the gunfire on the bank, and wanted to pile up all the good things on the defense line of the mountain.

"Father, it's not suitable."

Young Master Feng pressed his forehead that was beginning to throb in pain.

"Duck concave is a must pass. There are shoals and reefs, which are suitable for deployment. On the contrary, Duanhunya and Heifengtan have complex terrains, which are not conducive to operating shore artillery."

The fact is exactly as Feng Kai expected, after three trials against the current, the Xihu people's clipper finally decided to head towards Broken Soul Cliff.

The leader of the team this time is the little leader who confronted Donghu against the wind boat at Bailukou before.His warship was hit by skyfire and lightning, and he survived by chance, but the sailors who followed him died and were injured very tragically.

The boat is the value of the head. Without the warship, the little boss's status in Bailukou has plummeted, and he almost became an ordinary sailor.

Fortunately, he had voted for King Zuo Guli earlier, and relying on King Zuo's relationship to recover, he got a new boat customized by a southern merchant.Although the boat was in hand, the little boss was holding a sigh of relief in his heart.He challenged the patriarch of Yesaha many times, wanting to rely on his bravery to avenge his shame and regain the right to speak in Yesaha.

This is also the task assigned to him by Zuo Wang.If he can't establish prestige in a short period of time, then he is worthless to King Zuo.

He proposed the plan to forcibly cross Broken Soul Cliff.Inspired by Donghu's sailing boat, the little boss reported in detail the astonishing features of Donghu's sailing boat to Zuo Wang's envoy.The new warship sent this time is the result of the Southland merchants learning from the reverse sailing ship. They also used the triangle sails and masts, and the speed of the ship has indeed increased.

But the secret of how to adjust the mast and sail is still not understood. The new warship cannot rely on the mast and sail alone like the Donghu ship, and must be supplemented by manpower.Even so, the triangular sail saved a lot of effort, making it possible to travel against the current and wind to Heifengtan.

"Since we can reach Heifeng Beach, then it is also possible to cross Broken Soul Cliff!"

The little leader looked at the leader stationed at Bailukou with a determined face.

"There is a shoal between Heifeng Beach and Broken Soul Cliff. We can rest there for half a day. When the sailors regain their strength, we will head straight for Broken Soul Cliff. After passing the cliff, there is a river beach where we can camp!"

For the barbarians in Bailukou, this plan is undoubtedly radical.After so many years, I have never heard of anyone who can go up the Wuzhi River against the current and penetrate deep into the hinterland of Yechao's frontier army.

But that day when the Donghu sailboat entered the river mouth, many Hu riders saw the power of the reverse sailboat, especially the Donghu people also took out the sky fire thunder, which really gave a huge blow to the Xihu people who claim to be the people of the gods.

How can it be?Isn't the Holy Witch of Huo Lei protecting the Xihu tribe?Why do those alien races have supernatural powers!This kind of doubt gradually dissipated after the shamanism came from Ximo Zhihai.

——The shameless businessman stole the sacred weapon of the holy witch, and the despicable Donghu people deceived the gods and borrowed the power of the gods. These are all plots of aliens and traitors.

revenge!revenge!revenge!

It is the will of the Holy Witch of Huo Lei to destroy the aliens and traitors!

For the sake of the gods and the tribe, we must rush to the upper reaches of the Wuzhi River and chop off the heads of those blasphemers!

This was their fourth attempt, from Bailukou to Heifengtan, and today they advanced to the shallows only a few miles away from Broken Soul Cliff.

Further on, there is the gate leading to the middle reaches, Broken Soul Cliff.

The sailors were already exhausted from sailing all the way, and it was impossible to cross the customs again today anyway, so they could only stop the boat to rest according to the scheduled plan.

The little boss wiped his beard and looked at the towering and steep mountains around him, his eyes filled with burning ambition.

He shouted to the sailors.

"Leave the boat to the shallows, find a suitable place to anchor, and tomorrow morning, sprint to Broken Soul Cliff with all your strength!"
