The energy beam passes through the raw stone, and the covalent bonds between the carbon atoms dissociate instantly. The excess part falls off directly, revealing a smooth but dull cut surface.
Cutting is only the first step. Polishing is required to bring out the true brilliance of the diamond. After successfully polishing the first finished diamond, Xia Yu handed the job of watching the machine over to Walter, and he himself went to the underwater dock.
The U-2526 on the berth revealed a silver-white exterior, which was its color before painting. Xia Yu would repaint it after the final internal upgrade was completed and tested.
After climbing onto the 11-meter-high U-boat, the twin 20mm anti-aircraft guns on the hatch were completely out of service. Fortunately, Xia Yu had found the same anti-aircraft gun in the antique weapons market. He waved his hand and asked two maintenance robots to remove the old gun directly from the base.
After opening the hatch, Xia Yuxin returned to the interior of the submarine. Because the external power supply was connected, all the lights were on and the vision was still clear.
The cleaning robot wiped out all the footprints he had left behind, and the entire cabin was very clean.
Xia Yu quickly walked to the main diesel engine room. While looking at the blueprint, he asked the maintenance robot to remove the screws. It was a big project to take out the two 6-meter-long diesel engines, but for him it was just a matter of waving his hand.
"Swish~~"
After the two diesel engines were unloaded, Xia Yu directly put them into the space, and the originally cramped main diesel engine room suddenly became spacious.
He first cleaned the oil stains and conducted non-destructive testing on the cabin. After confirming that there were no problems, he waved his hand again.
"Swish~~"
Two brand new MAN V12-2000 main engines appeared out of thin air. Due to their compact size, the extra space is used to install the AIP system.
Diesel-electric submarines, as the name suggests, use diesel engines to charge batteries. Many U-boats were sunk when they surfaced to charge.
With the development of modern technology, nuclear-powered submarines have been developed, and conventional-powered submarines have also introduced AIP systems, which allow diesel engines to operate normally underwater without having to surface for recharging until the diesel is exhausted.
Of course, Xia Yu chose to increase the underwater endurance of U-2526. Such a system costs only a few million US dollars. Coupled with the main engine vibration isolation system, even an antique from the last century can enjoy the riding experience of the 21st century.
Leaving the maintenance robot here to be installed and debugged, Xia Yu went to the battery compartment next door and packed up all the antiques inside.
By the way, there are also those antique torpedoes in the torpedo room. The bullets can still be fired decades after their expiration. Since the torpedoes have been expired for so long, it’s better to run as far away as possible for fear of being exploded!
The remaining torpedo tubes were still brand new, but it was difficult to equip them with torpedoes of the same caliber.
No, maybe we will have to drive the U-2526 out to fish in the future. If we don’t have torpedoes, will we use anti-aircraft guns to fish?
After careful consideration, I decided to dismantle one, study it and imitate a few hundred rounds. It would be best if I could add a remote-controlled detonator and wait for it to explode when it hits a school of tuna.
"Bang~~"
All the stunned fish floated to the surface of the sea. Isn't this more convenient than fishing?
This is illegal in the country, so it can only be done abroad, but he doesn't make any profit from it.
With the help of robots, Xia Yu modified the submarine much faster than expected, and all three major components, namely the diesel engine, motor and battery, were upgraded.
After software simulation, the original speed of 17.2 knots was increased to 37 knots for a single system, and the dual-system hybrid can reach a maximum speed of 47 knots.
Although it is only half of the Shirayuka, it is a modification of a real-world antique submarine, so such data is already very good and one cannot ask for more. In addition, the Shirayuka is suitable for two people to travel, while the U-2526 (modified) is suitable for family travel.
If you are not married, you can still enjoy your two-person world, but once you are married and have many children, you will have to consider this issue.
It's like a man buying a car. When he's young, he thinks about buying a sports car in the future, or at least a coupe. But when it comes time to buy or replace a car, it's either an SUV or a station wagon, the bigger the better.
Rich people also have their own worries. A plane that is too small cannot do, a yacht that is too small cannot do, and a submarine that is too small cannot do either.
The large capacity comes at the expense of a low diving depth. Before the U-2526 (modified) and the upgrade, the maximum diving depth could only be 240 meters. After all, the hull structure cannot be changed.
This depth is enough. With the Aquaman buff, you can dive into the seabed without a submarine.
A few days later, Xiao Jiang's complete set of diamond jewelry was completed and was ready to be given to her on June 12th.
They should have returned to China by this time, and once his U-2526 (modified) was completed, they would set off back to China.
With this in mind, Xia Yu took the Amber Room back to the main castle. It was just dawn outside and everyone on the island was asleep except for the maid on duty, including Xiao Jiang from next door.
He immediately had a bad idea and opened the secret door between the master bedroom and the second master bedroom. Sleeping Beauty was lying on the big bed in the middle and snoring loudly!
Last time you played tricks on me, this time I have to play tricks on you.
Xia Yu tiptoed closer, then pounced on Xiao Jiang like a hungry tiger, crashing heavily into his body.
"Bang~~"
The mattress absorbed the impact and bounced back onto Xiao Jiang who was in a sweet dream.
Jiang Baiying only remembered that her body suddenly became lighter, as if she was floating in the clouds, and then she fell into a bottomless abyss in the next second.
“No~~”
I woke up suddenly and saw that I was not falling, but was being held in the arms of my senior, wrapped in a quilt.
"Really? You can't even sleep well. Is this a nightmare?"
The movie star came online, and Xia Yu asked with concern.
"Senior, why are you here?"
"I came to see you. You've been so busy these past two days."
My dear, there is more to this chapter. Please click on the next page to continue reading. It will be even more exciting later!
