"I had known it, I wouldn't have designed this type that is easy to install but not easy to disassemble." Luo Huai muttered while repairing the machine.

But he was in a hurry at the beginning, and if it was designed to be easy to disassemble, the difficulty of manufacturing and assembly would definitely be higher.

The design of his current machine is to make it easier to make the magic array board manually. After assembly, the magic array will be further reacted and combined, so as to synthesize a complete magic array in one piece. Otherwise, it will not be able to install it, so there is no need to consider disassembly.

The situation of the elves was a little embarrassed. The dwarves learned the technology of making this machine. They received several of them from there, but the machines were all useful, so this one could be used for research.

Then there was nothing. Once the shell was removed, the entire elf was stunned.

This level of damage cannot be repaired. The crash course only learns how to make and assemble it. The magic array that has been changed twice can't be repaired.

As for making another one... I am eager to use machines everywhere, so I don’t have the time and energy to do a research project for them.

Originally Mill was going to go to the site to observe the production process, but when he heard that the inventor himself had arrived, he rushed over to inquire all the way.

"I don't know if this is possible." Mill asked carefully from the side.

"Some difficulties." Luo Huai himself was also thinking about the possibility, but this involved a question he was thinking about at the beginning.

"The reason why the machine can purify food is that it has a precision control system is that food is dead. In other words, some details that are not cleanly processed can be achieved by increasing the intensity, and there is no need to worry about causing too much damage to the food. After all, they are dead anyway. Even if they are covered with a layer of skin, they are just a matter of eating two bites less."

But living creatures are not good. Increased purification power may cause damage to life. It is like high-temperature sterilization can be used to sterilize bowls and chopsticks, but it cannot be sterilized directly by hand. Unless you are determined to ignore your hands, no one will stop you.

"Indeed, this is a question." Mill thought for a moment and agreed.

But he seemed to have some clues and looked around.

"Teacher, is that?" An elf seemed to have guessed his thoughts and picked up a bottle of potion.

"Yes, that's it." Mir's eyes lit up. Without even having to praise, he gave the potion to Luo Huai.

"This is..."

"This is our latest drug for elimination of fel energy. It is softer, but the effect is not that strong. I'm wondering if it's possible to cooperate with the machine."

"Yes, the medicinal properties are mild, and it may be used to alleviate the damage caused by machine rays to the active body." Whether it is research or invention, the effect of teamwork is always reflected in mutual inspiration.

So Luo Huai did not choose to go to the front line with other support teams, but stayed in this laboratory for a day. It just so happened that the elf's research institutes were all night owls. They had plenty of time to make various attempts. Anyway, someone could repair the machine now.

...

At night, the demon's arrogance was still not able to calm down.

The offensive and defensive battles in Black Stone Mountain have been going on for several days. The demons rushing to this place surrounded the mountain, and it was irritated.

Although the dwarves had a stronger protective power, they fought day and night without stopping. Even if they had endless energy to smash the iron, they could not keep wielding the hammer to smash the annoying demon's head.

And even more deadly, they were cut off from the main sources of food and water.

The entrances and exits on the surface have long been useless, and some narrow tunnels and shallow ones have been discovered by the demons. Only the deeper small passage to the distance is still there, but even dwarves who like to mine and iron, they cannot stay deep in the ground for too long, otherwise bad things will easily happen.

They are now mainly relying on stored food and some groundwater to support them.

However, the dwarves have always had a lot of appetite. The fields near the Black Rock Mountains are always indispensable for hunting. They also like to eat seafood by the sea, but now they have nothing left. They can't fill their stomachs by drinking water!

The dwarves' ambitions were hit.

"There are too many demons, and the elves and the others cannot break through..." Inside the fortress, the dwarves who were resting sat around in front of the stove.

It would be great if there were help from the elves. They could use magic to create a lot of food. Although they were all vegetarian dishes, it was better than nothing.

As for teleportation magic... there are so many demons outside, and the evil energy soars into the sky, and the energy position around Black Stone Mountain has become unstable. If you use teleportation randomly, you may get stuck in the wall without a level.

It just so happened that Black Stone Mountain was full of walls.

Furthermore, the teleportation spells usually require high-powered Olympiad mages. There are not many such guys here. The elves are more good at natural spells and transmitting waste energy. They can't hold on if they can't go back and forth a few times.

"well……"

Hunger, a word permeates all the dwarves here, and since yesterday, the food that everyone can get has decreased.

Many dwarves even had a bold idea... Many demons have been transformed by evil energy, which eroded wild creatures. To some extent, is it also considered a kind of food contaminated by evil energy?

Well, just thinking about that smell is a bit disgusting.

But this has been recorded as a reservation option. If you really have nothing to eat then, you can only take this risk.

The shadow of the dragon clan has not been seen for a long time. Alas... After all, the races on the ground have no ability to resist the demons. The murdered demons returned to the void and resurrected, and then made a comeback. The only loss during this period was that they were scraping off a little soul fragment by the guardian formation.

At this consumption rate, all races may not necessarily consume more people than demons if they pile up.

The final ending must be to completely kill the demons by relying on the existence of the first echelon.

Tired.

Sighs are getting more and more, and they are connected together.

And bad news comes immediately - a very powerful existence appeared among the demons who siege the city, and its form is like a dragon!

"What?"

The dwarves couldn't believe that the dragon clan is the incarnation of the power of order, and the body eroded by evil energy will only be dissolved, and it is absolutely impossible to coexist.

However, the facts were in front of me. The dwarf warriors on the fortress wall clearly saw a flying dragon full of evil energy flying towards this side. There was still a trace of dragon power in the roar that was blurred by evil energy!
