"Is this your new development?" Touron sat in the improvised shed, his hands laboriously lifting the iron cannonballs in the wooden box, "an iron ball?"

Rand was about to measure the thickness of the iron plate with the caliper in his hand, when he heard Touron's words, he cleared his throat and said: "Its name is *, it should be quite powerful, you should be careful, although it needs a flame to ignite, but it cannot be ruled out that the high temperature will cause the extremely adhesive fuel inside to leak." ”

"*?" Touron was a little puzzled, "haven't you already mobilized a large amount of tar and coal to the town of Cabin?"

Rand nodded, and after his deliberation, he found that the wall of fire made of tar and coal could withstand the onslaught of the beasts, but that method could only be a passive defense, and once the beasts were scattered, Rand could not fill every possible invasion location outside the cabin town with flames.

And *can indeed be used as a main attack weapon, Rand uses a thin iron plate with good toughness to condense the shell shell in the mold, and when the fuse is ignited, * explodes the moment the fuel is ignited, and the area within five square meters will be covered by sharp iron pieces and fire.

The means of projecting this cannonball are also very simple, Rand made a miniature version of the catapult overnight, and by adjusting the length of the fuse and the pull of the catapult, it can ensure that the herd and the commander of the alien can be attacked from a long distance.

"*, it's more flexible, it's more offensive than defensive, and I won't use the wall of fire outside the cabin town unless it is absolutely necessary!" Rand took a deep breath, "Coal and tar are very important heating resources, and they produce a lot of toxic gases when they burn, we need to watch the wind direction to determine the best time to use it." ”

Rand mounted a metal roulette on the fuel machine in front of him, and the edges of the metal roulette were evenly distributed with grooves and toothed edges, which were sharpened.

In the absence of precise tools, Rand made a measuring stick out of iron bars to his own standards and quickly got to work.

Rand has always been dissatisfied with the speed at which today's craftsmen make weapons and tools, and after his research, he found that the time spent polishing and cutting tools was a large proportion.

With the help of the huge power brought by the camshaft rotation of this fuel engine, this problem can be solved.

After the Rand filled the engine with fuel and started it, the expanding air in the cylinder drove the piston up and down rapidly, and as the amount of air filled increased, the metal wheel disc mounted on top of the camshaft reached its peak.

Touron felt a powerful air current, which only indicated that the metal wheel was revning at a terrifying level.

"This is my new little petrol engine, it's a little less powerful than the one in the mine, it only has three cylinders, but it's enough for simple cutting and grinding work!" Randt picked up the steel pipe on display next to him and approached the metal roulette with the marked mark.

When the steel pipe came into contact with the metal wheel, the fire flickered, and the tough steel was almost instantly broken in front of the machine, and in less than ten seconds, a hollow steel pipe with a wall thickness of seven millimeters was sawn off, and the fracture was polished extremely smooth.

Rand found that the power provided by the cylinder could be used on almost any machine, such as a hole punch or a cutting machine, and that it could be changed at will by simply changing the drill bit and cutter.

That's a lot faster than manual work.

It takes half an hour or more to polish an arrow by hand, while this machine only takes a few seconds.

The purpose of all the devices that RAND has made so far is to make production work faster, easier and easier to operate.

"My lord, forgive me for being rude, do you know what I've been thinking about lately?" Touron asked with some emotion as he looked at the magical machine in front of him.

"How to defend the territory at the hands of beasts and barbarians?"

"No, more often than not, I'm wondering where exactly you learned how to make these machines, I've read a lot of books, and I'm sure no alchemist or fabrication in the world can make this kind of machine, and judging by your previous performance, you've never learned anything like it. Touron thought for a moment, and said as if jokingly, "You feel like you've suddenly changed your soul." ”

Randt paused for a moment, then stopped the fuel engine as if nothing happened, looked at his subordinate, and asked seriously: "So do you think this transformation of mine is good or bad?"

"Of course it is good!" said Touron without hesitation, as he tried to explain, "My lord, I dare say that you are undoubtedly the most prestigious among the people of all the lords who have served in the Kongdu Domain, and you must have heard that in the eyes of the upper nobles the lives of their subordinates and commoners are worthless, but I think that unlike them, you are merciful to the people, and have great wisdom, and in time you will surely ascend to the throne of the supreme. ”

What kind of person am I?

Rand thought for a moment, feeling that he was not an idealist, that he was not fanatical about the pursuit of something or honor, that he did not have the consciousness of seeing himself as a savior, that he had not thought of changing the world in his own power, and that saying these words in his current strength would only cause others to laugh.

He can show his kindness to the people, but he can also show his ruthlessness to the enemy, and he is never soft on interests, as can be seen from the incident of Ziluo, Rand is not a soft-hearted person.

Benevolence and fraternity, these words are not suitable for the rand, and in fact, any qualified person in power has nothing to do with them.

It can be said that he is a person with a particularly strong sense of camp.

God loves the world and only the world that belongs to Him.

Rand was merciful to his subjects, and only to those who supported him.

So it is with God, and so it is with man.
