Someone opened the window, and the slightly cold spring morning breeze entered the room with the scent of earth.

The Duke of Winton, who had been awakened from his contemplation, slowly raised his head and asked the Deputy Minister of Intelligence, who had just walked in, "Hasn't there been any news yet?"

The deputy minister swallowed a mouthful of saliva, and when he saw the bloodshot and tired eyes of the Duke of Winton, he knew that the Duke had not rested well last night because of worry.

But he brought news that disappointed the Duke.

The deputy minister shook his head.

"You mean, after my son disappeared quietly for five days, you as an intelligence department monitoring the entire Tieliu Kingdom, don't even have any news?"

Duke Winton's words did not deliberately suppress his anger.

This made the deputy minister feel a wave of fear, who knows if this anger of the Duke is due to Bran's disappearance, or is it directed at his own incompetence?

"I'm sorry, sir. Our intelligence department has been hiding and protecting Lord Bran in the shadows, but once Lord Bran arrived in Tallinn, our people could no longer trace Master Bran. "It's full of Norrington gendarmes and troops, as well as some specialized spy services, and our men quickly lost contact with ...... after entering."

"So, the last time you saw Bran was in Tallinn?"

"Yes, but that was a few days ago, and we can't be sure if Master Bran left there. The deputy minister wiped the beads of sweat from his head: "There is no news from the caravan of the Blue Star family, and Lord Bran seems to have evaporated from the world." ”

"He must still be in Tallinn," the Duke of Winton guessed Bran's purpose almost without difficulty, if it was for the Norrington girl, then Bran would never leave easily until he achieved his goal, "Send some more people to find Bran and bring him back alive for me." ”

"This ...... If a large number of spies are dispatched, the Norrington family may consider us hostile, and in case of more serious consequences......," said the deputy minister, not without concern.

"More serious consequences?" Duke Winton suddenly laughed, shook his head and said, "Just that old fellow Rob? If it weren't for the Holy See, I would have gone east and turned the Norrington family into history!"

......

"Well, that's what you say, the ...... that can move on its own," the valet reached out and touched the strange-looking machine, and the first thing he thought was that it was very complicated and extremely cumbersome, and just looking at the numerous bolts and axles on it was enough to give him a headache.

"Locomotives. Rand sat aside, holding a strangely shaped iron rod in his hand, which was the "key" to the locomotive's start, because the method of changing electricity by hand was too cumbersome, and there was a shortage of electrolyte and pure lead and other materials needed to make batteries, so the machine that Rand completed was started by pure hand.

In order to reduce the occurrence rate of failures, Rand streamlined other unnecessary functions.

Due to the simplification of the function, the locomotive was not too difficult to build, but there were some problems in the manufacture of ball bearings, and this kind of parts that required stamping took Rand a full five days to complete.

"How is this thing going to move? Do you need to put two legs on it, and he'll stand up like a human and walk forward on his own?" the personal servant bent down, the thing looked very clumsy and heavy, he had just tried the feel, and used all his strength to push the iron lump, but it didn't move.

"The locomotive I built is not a Gundam. Rand gave her a blank look and pulled out an iron wheel from his assembly room, covered with a pitch-black rubber-like substance, "Put the tires on and you can move like a horse-drawn carriage, except that it is powered entirely by itself, without the need for livestock or manpower." ”

In order to make tires, Rand also spent a lot of effort, and it was difficult to get hold of the rubber used as a material for making tires, so Rand ordered people to go to Lindong City and buy a large amount of gum from merchants.

Dozens of barrels of gum can barely be used to equip four tires.

Fortunately, gum is cheap enough, and people haven't realized what the potential of this sticky stuff is.

In order to cope with the harsh traffic environment on the mine, Rand specially made the tread of the tires extremely thick, even if there are sharp stones, it cannot be punctured.

"Come over and help. Rand commanded the apprentices of the craftsmen, placing the tires outside the iron discs that served as brake discs.

The brake system Rand chose to be still old and excellent hydraulic brakes, the way to make a small hydraulic pump is much simpler than the gearbox, in the case of raw materials, any science and engineering dog who has studied mechanical engineering can easily complete the independent production.

Rand ordered the oil to be brought out in vats.

"It looks a little more translucent than the fuel used in the fuel engine. The valet soon noticed the difference.

"If there are too many impurities, it is easy to clog the oil rail, so I asked Miss Andy to do some decomposition and refining with her ability. Rand filled the fuel tank with an entire bucket, and then asked the apprentices to turn the oddly shaped iron rod into the engine and turn it vigorously.

As the apprentice spun the iron rod faster and faster, the engine eventually let out a heavy roar and billowing black smoke spewed out of the exhaust pipe.

"It seems that the starting method is no different from that of the fuel engine......" the servant muttered quietly.

"I'll show you!" Rand said, getting into the driver's seat before the servant could hold him.

Seeing Rand's excited look, the servant swallowed the words he had wanted to say back into his stomach.

Lord Lord, too, for some new type of unknown thing, you should let your subordinates try it when you experiment, what if there is danger?

Rand called the apprentices to his side and explained to them in detail the functions of each thing.

"Well, we have three pedals under our feet, press the leftmost one, and then manipulate the green joystick, push forward is forward, pull back is backward, and stop in the middle is stop. ”

"The pedal on the right is used to speed up, and the pedal in the middle is used to park, the operation method is very simple, I will cover it up for you. ”

In anticipation, Rand pushed the gear lever to the front and slowly released the pedal on his left foot.

The locomotive shuddered and roared, and after Rand's left foot was completely off the pedal, all four wheels slowly turned at the same time.

"It's moving! It's moving!"
