After seeing Chi Yan's forging skills, Sha Mo's admired five bodies threw himself to the ground, and followed behind Chi Yan step by step, if he wasn't a kobold, Lu CD would have thought in a lewd direction.

"My lord, I think the shipyards in the realm could be improved to increase productivity." Leah said.

After the weapon forging competition, Jona, Pute, Shamer and others all recognized Chiyan's ability, and no one doubted that Chiyan, who was a perfect-level weapon, could barely tolerate Chiyan's previous contempt, after all, a person with such a strong ability could accept it if he was a little arrogant.

After seeing Chiyan's ability, Lu Cheng also paid more attention to Liya's opinions, so he took a group of people to the shipyard to listen to Liya's suggestions for improvement.

"There are waterwheels in the territory, which is a natural power, and in the processing of wood, waterwheels can be transformed into processing equipment, which can improve the efficiency of cutting, bending, and drilling of wood dozens of times." "Also, it's too time-consuming to put the ships on the ground right now, so a dry dock should be built for the production of the ships, so that they can be built much faster." ”

"It is feasible to convert the waterwheel into processing equipment, but we don't have the corresponding design drawings." Haaschi wondered.

"Ahhh Leah smirked.

"As long as it's as effective as you say, I'll reward you with 50 gold coins, you see." Lu Cheng knew that Liya was more greedy for money, so he directly gave a high price.

"Deal, high-five, swear." Liya ran to Lu Cheng and took his hand and slapped him, making Lu Cheng cry and laugh.

"So how should the dry dock be built? I can't make a dock door. Lu Cheng asked.

"It's not difficult, with the current technology, you can make a self-floating docking door first." Leah explained.

"Self-floating dock door?" Although Lu Cheng is a scientist, he does not understand many ancient mechanical facilities.

Leah took out paper and charcoal and sketched on the spot.

"You see, we first dig a pit with a narrow cross section on the land near the sea, and then dig a deeper box pit on the side near the ocean, and then make a box buoy with the same length and width as the box pit but different heights, this box buoy is the self-floating dock door we need, and then the dock door and the inner wall of the dock are linked with steel rails to ensure that it will only move up and down, and then the buoy itself should be relatively strong, at least the main structure should be made of steel bars, preferably an all-steel structure, Of course, the cost is high, the manufacturing is difficult, and the effect will be better. ”

Leah stumbled on a sketch.

"Usually the self-floating dock door is floating on the water, that is, it will block the seawater from the dock, because it is necessary to seal and waterproof, at this time, it is necessary to block the waterproof material along the perimeter of the self-floating dock door, and I think you can use the viscose produced by the alchemy workshop to waterproof. Then when you need to introduce seawater into the dock, you just need to fill the water inside the dock door and sink it, and when the dock door is about to sink to the bottom, seal all the openings of the dock door, and then add a heavy object to the hook outside the dock door to let the dock door sink, so that the seawater can enter the dock. If you need to raise the dock door, throw away the heavy objects hanging outside, and the dock door will float up the track, and when the dock door is raised, the seawater in the dock and the dock door will be discharged with the power of a water wheel. ”

Lu Cheng was amazed after listening carefully, Liya's idea is completely feasible, it is nothing more than that the final discharge of seawater will be slower.

"Yes, this is indeed feasible, but the final discharge of seawater may be relatively slow, each waterwheel discharges only a few tons per hour, and there are thousands of tons of water in the dock, wouldn't a waterwheel take ten days and half a month?" Lu Cheng asked.

"Ahh "The dock should be connected to a long aqueduct to the south side of the river, parallel to the river, and then a row of large two-wheeled waterwheels should be built on the riverbank, and the big wheels are in the river, and the wheels are on top of huge wooden planks, and the water hits the planks on the planks to drive the waterwheels to turn, and the other side is set up in the drainage ditch, and the wheels are loaded with containers for taking water, and the water is discharged into the river by the rotation of the waterwheels." ”

"Miss Ben has estimated that if you set up a row of 10 waterwheels with a diameter of 20 meters, you can discharge 1,000 tons of water per hour according to the flow rate of the river, and when you don't need to drain water, these waterwheels can be used for the processing of boat parts, killing two birds with one stone."

"10 large water wheels with a diameter of 20 meters!" Lu Cheng was sweating profusely, the cost of a 10-meter diameter waterwheel in the territory was more than 50 gold coins, and the cost of a 20-meter diameter waterwheel was definitely not as simple as doubling, and it was also a two-wheeled waterwheel, and the cost of a waterwheel in the most ideal state had to be more than 10 times that of the original version, that is, 500 gold coins, 10 units were 5,000 gold coins, which was also a huge investment for Lu Cheng, who had deep pockets.

"Well, if the dock is to be expanded, more needs to be built in order to speed up the drainage, and the more waterwheels are built, the more ships can be built at the same time." Leah continued, "The largest hundred-ton ship that can be built right now can be built with more than 25 ships in a standard 100×30 dockyard at the same time. Moreover, the dry dock is easy to expand in the later stage, such as expanding to 200×30 large, and can build more than 50 100-ton ships at the same time, or more than 4 100-ton ships. As long as you want, you can also expand to 300 meters in length, 500 meters in length, and the increase is nothing more than the number of waterwheels and the cost of basic materials. ”

What Liya said makes sense, Lu Cheng's goal is to build a large and strongest fleet, and the investment of 5,000 gold coins is nothing.

"Okay, I'll take care of this matter, and if you need anything, just come to me directly." Lu Cheng no longer hesitated, and decisively agreed to Liya's seemingly crazy dry dock construction plan.

"Ahaha, thank you, lord, I'll arrange it! Let's go to the site first. Liya happily high-fived Lu Cheng and swore an oath, and then ran away with a smoke, and Lu Cheng's expected scene of asking for a reward did not happen.

"Hehe, that's a crazy plan, but I like it." Chi Yan looked at Leya's distant back, and the corners of her eyes flashed, "Lord Lord, I find that I like you a little, if you can let this little girl toss around like this, it seems that the territory will become more interesting in the future." ”

"Compliment, what Liya said makes a lot of sense, I think her plan is still quite feasible." Lu Cheng said confidently.

"Do you know how many sets of ingots are required for that box-shaped dock door if it is made of all-steel?" Red Flame asked with a smile.

"Huh? How much? ”

"2000 sets of ingots!"

it!

Lu Cheng knelt down, the price of a group of steel ingots on the exchange cost more than 5 gold, and 2,000 sets of steel ingots cost 10,000 gold coins! His sister's is twice as expensive as a waterwheel!! Why didn't Lyati mention it! It's over, I've all agreed, can I still regret it now?

"Do you know how many sets of cement are needed for a shipyard of 100×30?"

"How much..."

"5000 groups!"

呲~

Lu Cheng was stimulated to vomit blood, the price of a group of cement is more than 2 gold, and the price of 5,000 groups is 10,000 gold, why didn't you mention it! Why!

"Do you know how long it takes to dig such a big hole?"

"Say it, I'll hold on!"

"Based on 2 cubic meters per person per day, you need 500 people to dig for 20 days, 1,000 people to dig for 10 days, and 2,000 people to dig for 5 days! The cost of labor and tools is more than 5000 gold coins! ”

"Others, such as steel rails, dockyard equipment, etc., cost more than 5,000 gold coins."

Lu Cheng was almost unsteady, and asked with difficulty: "Say, how many gold coins do you need?" ”

Chi Yan shook his red hair and looked at Lu Cheng with subtle eyes: "Based on the above, I judge that according to Liya's plan, you have to be mentally prepared to pay more than 32,000 gold coins, which is still the cost of the current scale." ”

Lu Cheng knelt directly, now his daily income is less than 2,000 gold, and he has to go without food or drink for 20 days to afford the cost of building a dry dock, which is simply crazy! Lu Cheng hadn't felt so poor for a long time, and he had to sell more than 500 dwarf suits to make so much money! How do you have to fill such a big gap, and you have to increase your income significantly, at least your daily income must reach more than 5,000 gold coins!

"Red Flame, what level of blacksmith are you?" Lu Cheng's first thought was to increase the sales of dwarf suits, and Red Flame's blacksmith level was obviously much higher than Shamer's, so Lu Cheng asked tentatively.

"Oh, is the lord finally going to attack me?" Red Flame squeezed her eyes coquettishly.

"Don't make a fuss, I'm serious, I don't mean anything else." Lu Cheng supported his forehead, Chiyan's personality was really unbearable.

"Haha, Lord Lord, it's really interesting, do you want me to help you build equipment and make money?" Red Flame put away his joke and asked with a serious face, "Lord Lord, before I answer your question, I want to ask you a question. ”

Lu Cheng nodded: "No problem, you ask." ”

"Why do you pay your people? They don't need to be paid to work for you. Brown eyes stared at Lu Cheng tightly without blinking.

"Because I want to share the joys and hardships with the citizens, so that everyone can live a prosperous life is my goal, and I will not let my citizens not even be able to afford a bowl of noodles, even the most ordinary clothes, and even the most basic food and clothing." Lu Cheng said seriously.

"Haha, why are you so serious, I'll tease you, okay, I'll help you make some weapons when I have time, but all this will be after I clean up the bandits outside the territory." Chiyan suddenly laughed, "By the way, I'm a little hungry, I haven't had a good meal until now, it is said that the food in the noodle restaurant is very good, I will go to fill my stomach first and then work, you won't charge me for food, right?" I'm poor! ”

After Chi Yan finished speaking, he patted Lu Cheng's shoulder hard, Chi Yan, who was almost the same height as Lu Cheng, had a lot of strength in his hand, and Lu Cheng felt that his shoulder was about to be dislocated.

"I'll go first, you go on, Shamer, you go to the blacksmith shop first, I'll come to you after I'm rested."

"Hey, Red Flame, you answered me, what level of blacksmith are you!" Lu Cheng shouted as he looked at the red flame who was striding away.

"So-so, Heavenly Rank Epic!"

it... Epic?

it... Epic!

Kneel!
