As Rand had guessed, the hyena didn't last long in front of the ancient torture instrument, which also confirmed the terrifying rumors about the Iron Maiden, who could make him succumb no matter how hard the bone was.

When the bloodstained road map was placed on Rand's desk, it had been less than an hour since Rand had left the dungeon.

The hyena is described very clearly, so detailed that Ziluo marks which inn he will stay at night, he has been tormented by that thing and has a mental breakdown, and only wants to die to get rid of it.

"Send this map to Payne. Rand carefully marked a few points in ink on the drawing, and instructed the warden, "Take care of the hyena, I am ready to execute him publicly on the school grounds in three days." ”

"Yes. The warden nodded, took the map marked by Rand, and asked, "Do you have any other orders to bring to Lord Payne?"

"Let him lead the cavalry immediately! Be sure to intercept Ziluo before he enters Lindong City!" Rand said very seriously: "Tell him that you don't have to show mercy!"

In the secret duel between the two, Ziluo was already at a disadvantage, and Rand had no intention of continuing to stay, he planned to follow his father's example.

Although he was reluctant to think of a certain fact, he still couldn't deny that after the fusion of this body, his personality had changed somewhat, perhaps because of the blood inherited from his body, he had become more ruthless and iron-blooded than before.

This transformation is not good or bad, but in the current environment, Rand feels that it is still very necessary, he is not in a calm and prosperous world, but full of war and sword fire, cowardly and gentle character can not command the army and deter the enemy, only strong means can achieve control.

Don't be merciful.

In just six words, the fate of Baron Ziluo has been determined.

......

Versailles was carefully taken care of, and he himself may not have realized what his actions represented, but Rand was very careful to realize that this was a good start, and that the current air crossing army needed such a benchmark figure, and Rand decided to promote Versailles to the rank of commander of the recruit corps.

In today's low morale situation of recruits, they need a hero to motivate them, and as long as they see a series of rewards for their actions, they will train and fight harder.

Recently, the harassment of the air ferry territory has become more and more frequent, except for the troops necessary to maintain law and order in other villages and towns, Rand has thrown the rest of the army into the wooden house town, and after the nobles left the air ferry territory, Rand immediately sent people to take over the mines sealed by the nobles and capture the guards left behind by the nobles.

Since they want to turn against the nobles, now is the best opportunity, they left their hometown, and put the treasure mountain full of gold and silver in front of Rand, if he does not grasp this opportunity, Rand feels that even God will not forgive him.

During this winter, the farmers were unable to carry out the farming work, and Lan had to gather a large number of farmers and train them in the technical knowledge of mining minerals, and he had to race against time to develop.

The pace of digging the caverns by hand was too slow and dangerous, and Rand remembered some kind of powerful steel machine and felt the need to improve the mining technology for the time being.

Thermal power device, which is a machine that appeared as a heavy mechanical engine in his previous life, is called a thermal engine, and the working principle of this machinery is to use the heat energy generated in the combustion state of fuel, and then convert it into power and mechanical energy.

To put it bluntly, it is a fuel engine, and although it is not very difficult to replicate it in terms of the technology of the previous life, it may take some effort to give it the current state of the air ferry territory.

The main problem in front of Rand is the tightness, whether from the piston to the air pressure tappet or the water-cooled pipe in the engine body, there can be no leakage, if the cooling fluid leaks into the cylinder body, it will cause the tappet to break and break, and it takes more energy and time to repair it.

Precision to the point of being almost exacting is the source of the problem.

I'm afraid that it still needs to be solved by Oak.

As long as the seal is fine, the assembly step is irrelevant, the suction pipe needs to be installed with a filter to avoid causing sand or water to enter the cylinder block, the most ideal material for manufacturing the cylinder block is aluminum, this metal is very lightweight, and easy to fire and easy to form, but the embarrassing thing is that until today, Rand has not found any trace of this metal.

This kind of machine is simple to say, but it requires a lot of preparation, and in terms of heat dissipation, exhaust gas from fuel conversion, and ignition, none of which can be easily solved.

In his previous life, he graduated from an engineering major in automotive engineering, although his professional knowledge in that world did not help him, but here, it came in handy.

Like the distribution of the number of fuel in the four cylinders, it is necessary to manufacture a kind of nozzle like a shower head, each cylinder occupies one, and the four nozzles are welded side by side on a steel pipe with a middle pass, and the air pressure is created in the steel pipe to inject the fuel into the cylinder barrel to complete the combustion conversion.

This is not difficult, as long as the pipe is welded like the barrel of a gun gun, and polished with steel until it is smooth and unobstructed.

As other small parts of the engine, they can be made in the workshop of the melting furnace, and in addition to fastening parts such as bolt rivets, the workshop can also make the drill bits and arms that are used with the engine, which is the most important thing.

Rand carefully drew 3D drawings on the drawings, the engine can control the combustion speed and the size of the conversion kinetic energy by inhaling the amount of air, and the air intake port should be equipped with a fast and reversible iron plate, and the opening and closing degree of it can be mastered by pulling the wire, so as to cope with the needs of various working conditions.

If this kind of machinery is manufactured, the mining rate of minerals will be increased several times, and Rand is confident that the overall military strength of the air crossing will be more than increased next year.

In the years of perennial war, steel, gold and silver were the hard currencies on the mainland, and with a steady stream of iron ore, it was difficult for the air to become rich.

With money, he can recruit troops and expand his territory, and with the Duke of Winton as a solid backing behind him, Rand doesn't have to think about other big warlords starting wars against him because of their technology and assets.

After a long period of development, the title of duke does not seem to be completely hopeless......
