"If I knew it earlier, I wouldn't have designed it to be easy to install and not easy to dismantle." Luo Huai muttered while repairing the machine.

But he was also in a hurry at the beginning, and if the design was easy to disassemble, the difficulty of manufacturing and assembling would definitely increase.

The design of his current machine is to simplify the difficulty of manually making the magic array board. After assembly, the magic array will further react and combine, so as to integrate and synthesize a complete magic array. What is the problem of dismantling.

The situation of the elves is a bit embarrassing. The dwarves have learned the technology of making this machine, and they have received a few from there, but these machines are all useful, so this is the only one that can be used for research.

Then there is no more, once the shell is removed, the whole elf is stupid.

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

As for making another one... Now that everyone is in a hurry to use the machine, how can they have the time and energy to make a research one for them.

Originally, Mir was planning to go to the site to observe the production process, but when he heard that the inventor himself was coming, he rushed over in a hurry.

"I don't know if there is such a possibility." Mir asked, watching carefully from the side.

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

"The reason why the machine can purify food is not only its precise control system, but also because the food is dead. In other words, if some details are not handled cleanly, you can increase the force to achieve the effect, and you don't have to worry about causing harm to the food. Too much damage, after all, they are dead anyway, even if they are skinned, it's just a matter of eating less."

But living organisms can’t do it. Increased purification power is likely to cause harm to life. It’s like high-temperature sterilization can be used to sterilize dishes and chopsticks, but it can’t directly sterilize hands, unless you are determined not to use them. Then No one stops you.

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

But he seemed to have some clues and looked around.

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

"Yes, that's it." Mill's eyes lit up, and he gave the medicine to Luo Huai, regardless of the compliment.

"this is…"

"This is the latest potion we've researched for dispelling evil energy. It's softer, but the effect isn't that strong. I'm wondering if it's possible to cooperate with the machine."

"Yes, the medicine is mild, and maybe it can be used to alleviate the damage of machine rays to living organisms." 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 all the elf research institutes were also night owls, and they had a lot of time to do various experiments. Anyway, the machines are now Someone can fix it already.

…

At night, the demon's arrogance still could not be quelled.

The offensive and defensive battle of Black Rock Mountain has been going on for several days, and the demons rushing here have surrounded the mountain peak, making it impenetrable.

Although the dwarves have stronger protective powers, they never stop fighting day and night. Even though they have infinite energy for blacksmithing, they can't keep swinging hammers to smash the heads of annoying demons.

And to make matters worse, they were cut off from their main sources of food and water.

The entrances and exits on the surface have long been unusable, and some narrow underground tunnels, shallower ones have also been discovered by demons, only the deeper small passages leading to the distance are still there, but even if you like mining and blacksmithing The dwarves can't stay in the deep underground for too long, otherwise bad things will easily happen.

They are now mainly supported by stored food and some groundwater.

But the dwarves have always had a lot of food. They are always hunting in the fields near the Blackstone Mountains. They also like to eat seaside and seafood, but now these are gone. Drinking water alone can't fill their stomachs!

The morale of the dwarves took a blow.

"There are too many demons, and the elves can't break through..." Inside the fortress, the dwarves who had their turn to rest sat in a circle in front of the stove.

It would be great with the help of elves, they can use magic to make a lot of food, although they are all vegetarian, it is better than nothing.

As for the teleportation magic... there are so many demons outside, and the evil energy is soaring into the sky. The energy position around the Black Rock Mountain has become unstable.

It just so happens that Black Rock Mountain is full of walls.

In addition, teleportation spells generally need to be a powerful arcane mage. There are not many such guys here. Elves are more good at natural spells, and they can't support the transmission of waste energy after a few times.

"Ugh…"

Hungry, one word runs through the hearts of all the dwarves here. Since yesterday, the food available to everyone has begun to decrease.

Many dwarves even came up with a bold idea... Many demons are transformed from wild creatures corrupted by evil energy. To some extent, they can also be regarded as a kind of food contaminated by evil energy?

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

But this has been written down as a reserved option, and if there is really nothing to eat by then, then you can only take such a risk.

The shadow of the Dragon Clan has not been seen for a long time, alas... In the end, how can the races on the ground have any ability to resist demons, and the killed demons return to the void to resurrect, UU reading www. uukanshu.com and then made a comeback, the only loss during this period was a little soul fragment scraped off by the guardian array.

According to this rate of consumption, all races may not be able to consume more people than demons.

In the end, the demons had to be completely killed by the existence of the strength of the first echelon.

Heart tired.

There were more and more sighs, and they became one piece.

The bad news came one after another—a very powerful existence appeared among the demons besieging the city, and its shape was like a dragon!

"what?"

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

However, the facts are in front of us. The dwarf warriors on the walls of the fort clearly saw a flying dragon full of evil energy flying towards this side, and there was still a trace of dragon power in the roar blurred by the evil energy!

"My beard, tell me it's not true..." The dwarves were almost dumbfounded.
