For Rand, the difficulty of making an agricultural locomotive is much higher than that of all the equipment assembled before, and he has been in the assembly room for half a month since the day he started, but the steel machine in front of him has not yet been assembled.

Compared with a separate fuel engine, the main difficulty in the assembly of agricultural locomotives lies in the driving aspect, which requires the combination of engine power and gearbox to fully transmit the power to the drive shaft, and then the drive shaft turns the wheels.

Theoretically, it's just a process of transferring engine power to the wheels.

It's easy to say, but it's hard to do.

Gearboxes require a large number of gears to be constantly tested to determine that a certain size meets the requirements of the RAND, and most importantly, the RAND requires more accurate ball bearings.

This accessory is technically demanding, and even with the help of Oak, it is difficult to increase its production.

The frame used to serve as the body of the locomotive had already been assembled, and given its purpose, Rand did not care about its appearance, but opted for the most primitive cockpit type, with the engine mounted at the front of the locomotive and the cargo compartment behind it.

This bizarre locomotive is based on the tractor of the former world of Rand.

Good value for money and extremely strong off-road performance.

In order to cope with the harsh driving environment, Lante wanted to make it a four-wheel drive, the ground of the mine is uneven, and when the front wheel of the locomotive is stuck in the pothole, it can also climb out on its own with the help of the power of the rear wheel.

Compared with front-wheel drive, four-wheel drive only has a differential between the rear wheels, which is connected to the drive shaft in the middle.

But Rand glanced at the gears and bolts all over the floor, and suddenly felt that his head was big.

"This guy, it's really hard......" The shadow leaned against the decorative stone pillars in the garden, basking in the sun comfortably, looking at Rand who was busy, and couldn't help but sigh.

Since he officially became Rand's personal guard three days ago, the shadow has been closely following Rand's side.

This guy is indeed a little different from other human nobles, not so much that he is a nobleman, but more like an alchemist, he always has some strange things in his head, and this morning he also said mysteriously, so that the shadow does not have to use that long knife in the future, he is ready to develop a weapon with more firepower and easier operation.

Shadow wasn't interested, he was confident in his skills given his childhood, and Randt's weapons such as flintlock pistols or* were still too dull in his opinion.

The time it takes to aim alone is enough for me to kill the opponent five times.

But Rand swore that Shadow would like the new weapon, and excitedly said a lot of technical terms, and Shadow was so dizzy that he didn't even remember a tenth of it, but simply remembered a few words......

What does it seem to be...... Free bolt, drum*......

Is the maximum * capacity of 71 or how much?

As for the name, Shadow remembers that Rand said it very tongue-twisting.

Bobosha*.

Shadow naturally didn't understand what these six words meant, and he only remembered the excited smile on Rant's face, as if he could sweep across the continent once this weapon was developed.

"Your Excellency. ”

As the shadow was boredly fiddling with the weeds under his feet, a soldier in a guard's uniform ran in, and although he tried his best to suppress it, the shadow could still see the joy in his heart.

"Huh, what's the matter?"

"The merchant ship of the Lanylus family arrived at the shallow waters. The soldier tried to calm his voice, but couldn't help but grin.

"Oh, then take them a little money and let them pass. Immersed in creation, Rand was completely unaware of the other things in the soldier's words, and he was worried that the crankshaft oil seal could not be installed, "It can't be that the size is not right, it should be fine, I obviously measured it with calipers." ”

"My lord, it's the merchant ship of the Rannyruth family!" the soldier reminded in a louder voice.

"What about the Lenilus family......" Rand said here, pausing suddenly, and then he seemed to remember something, and his mouth grew: "You mean...... Lanilus, Peruvian family?"

......

When Rand met Lanilus on the shallow waters, he felt his heart beat still, and after spending the winter, he was looking forward to the arrival of the Peruvian family every day.

Because the arrival of the Peruvian family represents the arrival of a group of excellent war horses.

Rand stood far away on the reclaimed land, the wind blowing from the direction of the shallow water with the smell of horse manure, and he looked at the large ship with more than twenty ships connected from end to end, as if he had seen his closest lover.

"Mr. Rand, my father values your cooperation very much, and since our last return trip, we have been actively scouring the major pastures in the south to select the best horses for you. Lanilus walked beside Rand and pointed in the direction of the shallow water: "When the river just began to thaw, we didn't delay for a day, and rushed from the south to the air ferry collar day and night, but the transportation of war horses and goods is different, these war horses are very poorly adapted to the water environment, and our crew also needs to divide manpower to take care of them, so the speed is much slower than usual." ”

"Thank you to your father on my behalf. Rand said sincerely: "War horses are by far my most scarce resource, and the air crossing without cavalry will be despised by other nobles. ”

"You solved this problem for me, and I don't know how to thank you enough. ”

"Your Excellency, you don't have to be polite, the Peruvian family has always kept their promises," Ranilus smiled, "and you have also kept our competitors out of the shallow water, as agreed in the cooperation agreement. ”

"I heard that a few days ago, the Bantu family had returned from the shallow waters in disgrace. ”

"The Capetian family has always kept their promises. Rand nodded.

"Let's take a look at the goods. Ranirus shrugged his shoulders, he pointed to the horses that were being pulled from the ship to the flat ground, and said: "These horses are pure Rudasia horses, one of the oldest classic horse breeds, with thick bones, good at jumping and running, with an average height of about 148 centimeters, and a docile personality, all between two and three years old, and there are no old horses or young horses. ”

"They come from the Dawn Ranch, which I have tested, and it only takes an hour to reach the 30-kilometre journey with a weight of 80 kilograms. ”

"Strong stamina is its strength. ”

"This is the most suitable breed for light cavalry. ”
