The countries of the pan-human camp are united on the surface, and because of their different races, beliefs, and cultural inheritances, it is destined that it will be difficult for them to urinate in a pot when there is no strong foreign enemy.

A hundred years ago, because the gods launched a divine war without a word, there were many broken things that led to subordinate kings following the war.

Now that Barbarossa is wide to the north, Karak does not have the devil's mouth to bleed it for the time being, and the other kingdoms are a little frightened. Arms expansion is inevitable.

Cervantes is not weak, and coincidentally, as a kingdom with a lot of mountains, it is also quite rich in mineral resources. It just so happened that Barbarossa's demand for iron ingots increased rapidly.

Cervantes remembered the idea of introducing lighting to increase mineral revenue.

I don't know if I don't ask, and I'm shocked when I ask.

Today, the Cervantes used soybean oil lamps instead of the legendary kerosene lamps, sometimes even with torches.

Not only is the light not good, but it is also prone to various accidents. For example, the torches are not maintained well, and several torches are extinguished in a row, trapping the miners underneath.

In a sense, this gives races with [Dark Vision] such as the Dwarves an advantage when it comes to mining.

And there is no such thing as railroad tracks in this world, and the ore below is all brought up by hand with two-wheeled carts.

There is a reason why the mineral output of human countries cannot go up at all.

In the past, the rotten mining level corresponded to the slag-like smelting level, and it was okay. Now that smelting and forging have been strengthened, it is a mining jam.

The Sevatis had iron ingots so much that at least Wren couldn't even pave some rails for them first.

So a series of gadgets appeared, starting with a wheelbarrow.

Tools are not necessarily good if they are big. Don't look at the large cargo volume of the two-wheeled cart, for many narrow mines, this thing is not easy to use. Secondly, the cargo capacity of each car is actually very particular, too much, which will waste the physical strength of workers. Sometimes it's smoother to be smaller, run two more times, and the efficiency is here.

Then, according to the physique of the miners, Rennes uniformly formulated the size of shovels and chisels. This thing involves ergonomics, and it has to be described in words, not a 10,000-word paper? Wren simply and violently made the Cervantes do what he said.

They did so, although they didn't understand it, and that didn't prevent the visible efficiency gains.

Then, Rennes began to buy the coal mines of Cervantes.

He's going to get a piston steam engine.

In fact, the steam engine has a history of more than 300 years before the crossing of Rennes, and can be traced back to the 18th century.

Wren can't handle the steam generator that is too complicated, and the simplified version is still fine.

But if Wren was ruthless at the beginning, it was not impossible for him to make a steam engine in the valley, but all kinds of materials were estimated to be ugly, such as the sealing of the piston, there was no rubber or anything, and he figured out that he could only make do with hemp rope.

Since Wren had Barend, the perfect tool-type disciple, the creation of parts or something, given a size and material requirements, Barende would get him properly, a set of boilers, cylinders, pistons, connecting rods and crankshafts, and the experiment of the steam engine had already been completed in the academy.

All Wren had to do was ask Barend to send the drawings to the Iron Hand Clan for expanded production.

Not every place has the conditions to engage in mixed wind and hydropower power generation.

These clean energy sources are good, but they are also greatly affected by environmental factors. Even if rivers do not freeze in winter, their flow is often drastically reduced, and power generation is very unstable without the increased wind to supplement it.

To put it bluntly, even before Rennes crossed, thermal power generation was the most stable source of power for the Celestial Empire.

Of course, pollution is another issue.

Since Wren decided to tinker with the steam generator, he unknowingly raised a group of mechanical engineers.

As a result, there were more people willing to join the physics school.

When a school can fully meet the needs of people in the three grades of high, medium and low, this scene falls in the eyes of those who care, that is...... The prototype of a perfect sect.

Highlight – from the point of view of faith!

This kind of sect that can perfectly meet the needs of believers is the most terrifying.

Some are noncommittal, others are worried.

For those rather contradictory comments from the outside world, Wren ignored them.

Just as Wren was ignoring what was going on outside the window and was bent on running wild on the road of the engineering dog, several big things happened in the world of Kaos.

Downs rushes to the workshop and finds Wren and Barend.

"Master, something happened all over the mainland at the same time."

"Huh? Let's talk about it. ”

"News broke out in many parts of the Southern Federation that underground races had invaded the surface. Several provinces in the eastern part of the Karak Empire are infested with colorful dragons. The western part of the Barbarossa Empire was actually invaded by orcs, because the mountains were covered by heavy snow and the transportation was inconvenient, so that the third town of 10,000 people was slaughtered before it was discovered by the center of the empire. Downs paused when he said this: "The most important thing is that a large number of people are missing in many places in the Kingdom of Cervantes. ”

"Missing?" Wren finally frowned: "What do you mean?" ”

"It's literally, more than 2,000 people in the whole town, and it's very strange that all the people have disappeared. According to the loiterers in charge of the survey - there are almost no traces of the battle. ”

"Almost?"

"Because of the heavy snow everywhere and the roads are impassable, it is easy to judge whether there is an invasion of foreign enemies. There was no snow yesterday, and there was no sign of a large number of people walking on the road to the town of Antina. The wanderers did not find any bodies. When part of the house entered, the stove was still burning. ”

Barende couldn't help but sigh, "What the hell. ”

Well, what this apprentice said might be hell in the physical sense.

"There is no trace of undead creatures and shadow creatures. ”

Wren blinked, thought for a moment, and finally held back: "We don't care." ”

"This ......"

"Have you forgotten? We are a school of order-neutral. If it doesn't mess with us, that's not our problem. Let the kings of the nations and their first sect be troubled. "Wren, who is obsessed with mechanical engineering and can't extricate himself, really doesn't want to care about these things.

Wren looked at his legend and thought to himself: In other words, under the reputation of the physics faction for 'restraint', there shouldn't be a stupid real jumping face, right?

Wren's apprentice felt more than once that his own [neutrality] was really flexible like his master's moral bottom line.

That's the reason, why does it sound so harsh at this time?

Wren didn't speak, and Tang Si, who was bent on helping a few juniors and disciples to impact the legendary realm, could only reluctantly retreat: "I will let the disciples in the school be careful." ”

However, Wren doesn't want to cause trouble, which doesn't mean that no one dares to jump his face.

A very sudden news came -

Elizabeth is missing!
