Even with a helmet protection, it is easily broken and the juice is splashed like a watermelon that has been dropped downstairs.

To do this, extremely terrifying power is required.

This shows how strong a mouse man has become.

The Senn couldn't even withstand his punch!

Seeing that his compatriots were killed one after another within a few seconds, and their deaths were miserable, the Mechanical Divine Cult Army was very angry.

They immediately fired at the Rat King under the priest's order to open fire. At the same time, they also fired grenades at him!

Although the Rat King's reaction speed was extremely rapid and he immediately began to dodge, several grenades still exploded beside him.

The violent impact makes it difficult for it to stand firm for a while.

This reduced the ability to dodge against artillery fire. Then, two grenades exploded on his torso, and a loud bang of steel breaking out.

The shell of the armor was destroyed.

The Rat King completely lost his balance and swayed his body staggering backwards.

Therefore, the direct hit of the third grenade was directly blown into the chest and pushed it away two meters away.

Even so, it did not fall to the ground, but instead kicked and rubbed hard in time with huge force when it was about to fall to the ground, and braked its huge body.

The rough stone brick floor was crushed into ravines by steel boots carrying about one ton and a half tons of weight.

Accompanied by a roar of unknown origin, the Rat King turned around and retreated.

He bought enough time for his subordinates to retreat into the castle. Then, he rushed into it.

The heavy castle gate, which was originally pushed by several people at the same time, could slowly close the door, was grabbed by the Rat King and pushed forward at the same time, and closed in an instant.

This wooden door is made of a mixture of wood and steel, and is extremely sturdy.

However, this strength is just to defend against their low-purity powder barrels.

In the face of such blasting grenades, it is still not enough to see.

Even, due to the different blocking mechanisms, there is no need to use grenades to bombard the surrounding area of ​​the door panel, and directly concentrate the firepower on the door panel to break it.

Luo Zixuan felt that the rat people in this plane still have some prospects.

Although they invented powder kegs mainly to explode mines and open up new mining and residential areas.

However, if you can make a powder barrel, you can make a medley gun sooner or later.

There is no hope that there will be further shell bullets.

The natural development of science and technology emphasizes gradual progress.

As long as the direction is right at the beginning, you can at least achieve success in a certain range.

Of course, Luo Zixuan could also see that if this plane continues to be so isolated, even if there is no intervention of the Supreme God, the development of technology will end when it reaches a certain level.

In the view of the God of Machinery, the upper limit of technological development of each plane depends on these four points.

1: Does this plane have sufficient resources to support the development of civilization?

Including wood, food, mineral deposits, etc.

The type and reserves of minerals are the most important.

Although the resources of each plane can be regenerated, it is still a bit slow after all, and the reserves are too small to satisfy the consumption.

2: Is the race in this plane stressed?

This includes whether the natural environment is harsh and whether there are a large number of monsters and hostile intelligent races in the country.

Survival pressure can force races to complete their own evolution.

Since there is no spiritual energy in this universe, there is no collective genetic mutation, and magic must be learned by believing in God, so when there is no favor of gods, the only evolutionary route is to develop technology.

Each plane will give priority to inventing mechanical technology that will improve its own survival status.

For example, there are many plains and mountains in the Sain field. After they created internal combustion engines and boiler rooms, they gave priority to steam trains to help them conduct more convenient long-distance transportation and cargo.

Since there is no large area of ​​water, when they encounter a lake and other terrain, they may only think of circling the railway along the edge, or building a bridge, laying railways on it to open traffic, without building steamships.

The Turtle Man, the ancestor of Orlani, whom I saw before, gave priority to building steamships because they had many waters in the divine realm and urgently needed water shipping.

According to the land area of ​​their field, it is normal to build steam trains at all.

Let’s take the lizard men of Darna as an example. The reason why they first created steam mining machines was because they did not have open-pit mines, and they were mines with very dangerous structures in the mountains. Most of them were still in the snow-capped areas.

This kind of mining efficiency is extremely low, so they urgently need machines that can mine safely and quickly, so they first applied internal combustion engines to this.

3: The average intelligence of the intelligent race in this plane.

There is no need to force it to be high. As long as it is not too low, you can create some very basic things.

For example, internal combustion engines are not too difficult, and they can be built sooner or later if they continue to develop.

In Luo Zixuan's view, the most important factor restricting the development of rat people lies in the second point.

In their field, sparrows are small and have all the internal organs.

There is no shortage of natural resources.

Moreover, the intelligence of the rat man is D. Although it is slightly lower, it is far from the level of E and F that is basically inseparable from the development of technology.

Then the problem lies in the pressure of survival.

Although I don’t know the details, based on the information I have collected so far, Luo Zixuan learned that the only enemy of the Rat Man is just some monsters that survive in the mine.

Some of these monsters can be easily dealt with with cold weapons, and some of them are slightly tricky. They can also directly move the powder barrel to blow up the passage and seal the monsters they found in the nest. Even if they really encounter any mutant individuals that are particularly difficult to deal with, the Rat King can easily solve them as soon as they come out.

They simply and easily deal with every crisis with this panacea method, and it can be solved smoothly.

Of course, there is no survival pressure.

If cold weapons are enough and can solve all the problems of the race, then naturally there will be no motivation to develop hot weapons.

No one would have thought that gunpowder had other uses - such as using propulsion to shoot iron sand bullets. The Senn was beaten to a mess by monsters, so he tried hard to find more efficient and powerful weapons under tremendous pressure, and finally invented the medron.

It can be said that the birth of the Match Rope saved the Sain civilization and saved it from being destroyed by monsters.

However, the subsequent scientific research triggered by this attracted the attention of the Supreme God. If Luo Zixuan had not taken time to save him, the Saen people would have become extinct.
