Popular science physics, teach a magic god?

The countries in the meta-human camp are ostensibly united. Due to their different races, beliefs, and cultural heritages, it is destined that they will find it difficult to urinate in a pot when there are no powerful foreign enemies.

A hundred years ago, it can be said that there were many incidents where the gods launched divine wars at the slightest disagreement, causing subordinate kings to follow suit and start wars.

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

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

Cervantes came up with the idea of ​​introducing lighting to increase mining revenue.

If you don’t ask, you won’t know. If you ask, you will be shocked.

Nowadays, Cervantes people use soybean oil lamps for mining instead of the legendary kerosene lamps, and sometimes even use torches to deal with them.

Not only is the lighting poor, it is also prone to various accidents. For example, if the torches are not maintained well, several torches go out in succession, trapping the miners below.

In a sense, this makes races with [dark vision] such as dwarves quite advantageous in mining.

Moreover, there is no such thing as railroad tracks in this world. The ore below is all brought up manually using two-wheeled carts.

There is a reason why the mineral production of various human countries cannot increase at all.

In the past, the poor mining level corresponded to the slag-like smelting level, which was just fine. Now that smelting and forging have been strengthened, mining is stuck.

The current iron ingots of the Servatis people are so at least that even if Ren wants to lay some rails for them first.

So a series of gadgets appeared, starting with the unicycle.

Tools are not necessarily good if they are big. Despite the large cargo capacity of the two-wheeled cart, it is not easy to use in many narrow mine tunnels. Secondly, the cargo capacity of each vehicle is actually very particular. Too much will waste the workers' energy. Sometimes it's smoother if it's smaller. If you make two more trips, that's where the efficiency lies.

Next, Wren unified the sizes of shovels and chisels based on the miners' physiques. This thing involves ergonomics. It has to be described in words. How about a 10,000-word thesis? Renn very simply and violently told the Cervantes to do exactly what he said.

They did it, even though they didn't understand it, it didn't hinder the efficiency improvement that was visible to the naked eye.

Wren then began acquiring Cervantes' coal mines.

He planned to build a piston steam engine.

In fact, steam engines have a history of more than 300 years before Ren's time travel, and can be traced back to the 18th century.

Wren couldn't handle the overly complicated steam generator, but the simplified version would be fine.

If Ren had been more ruthless, it would not have been impossible for him to tinker with the steam engine in the valley, but the various materials would probably be ugly, such as the piston seal, which had no rubber or anything like that. He figured he could only make do with hemp rope.

Since Renne has Barend, a perfect tool-type disciple, he can give him the size and material requirements for making parts, and Barend will make it perfect for him, including a set of boilers, cylinders, and pistons. , connecting rod and crankshaft were removed, and the steam engine experiment had already been completed in the college.

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

Not every place has the conditions for hybrid power generation from wind and hydropower.

Although these clean energy sources are good, they are also greatly affected by environmental factors. Even if the rivers are not frozen in winter, the water flow is often greatly reduced. Without the enhanced wind to supplement, the power generation is very unstable.

To put it bluntly, even before Ren's time travel, thermal power generation was the most stable source of electricity in China.

Of course, pollution is another issue.

Since Lane decided to tinker with steam generators, he has unknowingly cultivated a group of mechanical engineers.

As a result, more and more people are willing to join the physics school.

When a school of thought can fully meet the needs of people in the high, middle and low levels, this scene will fall into the eyes of those who are interested, and that is... the prototype of a perfect sect.

Highlights - look at it from the perspective of faith!

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

Some were noncommittal, while others were worried.

Rennes ignored the rather contradictory comments from the outside world.

Just when Ren was turning a deaf ear to what was going on outside the window and was running wildly on the road of engineering dogs, several major events happened in the world of Kaos.

Downs rushed to the workshop and found Renne and Barend.

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

"Huh? Tell me."

"News of underground races invading the surface broke out in many places in the Southern Federation. A large number of colorful dragons were raging in several eastern provinces of the Karak Empire. The western part of the Barbarossa Empire was actually invaded by orcs, because the mountains were blocked by heavy snow and transportation was inconvenient. The third town of 10,000 people was massacred before the empire center discovered it." Downs said this, then paused: "The most important thing is that a large number of people are missing in many places in the Kingdom of Cervantes."

"Missing?" Renn finally frowned: "What do you mean?"

"In a literal sense, there are more than two thousand people in the entire town. Strangely, all the people have disappeared. According to the wanderer in charge of the survey - there are almost no traces of battle."

"almost?"

"Because there is heavy snowfall everywhere and roads are impassable, it is easy to judge whether there is an invasion by foreign enemies. There was no snowfall yesterday, and there were no traces of large-scale people walking on the road leading to Antina Town. And the wanderers did not find it either. Any bodies. Part of the house was entered with the furnace still burning."

Barend couldn't help but sigh: "What the hell."

Well, what this apprentice said may be a ghost in the physical sense.

Downs said: "There are no traces of undead creatures or shadow creatures."

Ren blinked, thought for a moment, and finally said, "We don't care."

"this……"

"Have you forgotten? We are a [Lawful Neutral] school. If we don't get into trouble, it's not our problem. Let the kings of various countries and their first sects worry about it." Lei, who is obsessed with mechanical engineering, can't help himself. Well, I really don’t want to deal with these nonsense.

Renn looked at his own reputation and thought to himself: By the way, given the reputation of the physics department as a 'restraint', there shouldn't be any silly people who would really make a fool of themselves, right?

Ren's apprentice felt more than once that his [Neutral] was just like his master's moral bottom line, it was really flexible.

This is the truth, but why does it sound so harsh right now?

Ren didn't say anything. Tangs, who wanted to help his juniors reach the legendary realm, had no choice but to retreat: "I will ask the disciples in the school to be careful."

However, just because Renn doesn't want to cause trouble, it doesn't mean that no one dares to make trouble.

A very unexpected news came——

Elizabeth is missing!
