The roar of digging lasted for about three hours, and Thorin soon drove the construct to open up a cave for the newcomers to live in.

The constructs' intelligence level is somewhat weak in judging rock structures. Carl is worried that their unauthorized digging may cause collapse, so he only lets Thorin, who has relevant experience, be in charge of this matter.

After the fire elementals and drow who had traveled for three or four days fell asleep in the dungeons, Karl gathered everyone together to discuss how to deal with them.

"Those fire elementals should have a good talent for smelting, Thorin. They will work with you first. As for the rest of the drow, you can decide for yourselves who needs help."

After a period of running-in, Carl and his team have formed several working groups including scouts, logistics supplies, metal smelting, parts assembly and magic pattern drawing.

The two spellcasters, Carl and Carian, are the only two members of the magic pattern drawing team.

Hope brought a few drow to be responsible for cooking for everyone.

The addition of these new members actually does not help much to the overall efficiency. After all, what currently restricts the speed of construct manufacturing is mainly Carl's efficiency.

Jialian's magic pattern drawing speed can only be considered better than nothing.

"I'm fine!"

After hearing what Carl said, Thorin immediately raised his hand.

In fact, he had wanted to ask for some help a long time ago, but he felt that the drow were clumsy in smelting and forging, so he never said it.

"Should we assign some weapons to those drow? I feel like they could be of some help if we have to fight the fire dwarves or the elemental monsters in the tunnel."

At this moment, Bain on the side expressed his opinion.

As the leader of the scout team and the guard team, Bane actually has no other colleagues except Scorpion.

Carl assigned all the crude constructs that had been created previously to his control.

50 all-terrain construct tanks are quite intimidating no matter how you look at it.

But at the moment, it seems that Bain wants to recruit a few drow to work for him.

"Well, that's fine. You can discuss it among yourselves. However, Hope's logistics and Ying's assembly team must be given priority. When there are more people, we must prioritize food supply and weapon production."

Nodding, Karl simply let them discuss it themselves.

The next morning, the appointment of new members was announced.

Everyone is working hard in their own position, and everyone is working hard to get out of this hellhole.

But just when things were going smoothly, an accident happened.

…

"Lord Karl! The scout team discovered a group heading this way. They are all drow who have surrendered to the fire giants and warlocks."

In the underground arms workshop, Carl had just finished the fusion of souls and the drawing of magic patterns for another construct when he heard some not-so-good news.

Galian on the side trembled subconsciously. The magic pattern that had been drawn halfway quickly dissipated as the magic power was interrupted, and he had to draw it again.

The corners of Carl's mouth twitched slightly twice, and then he asked the member of the scout team who came to report:

"Where are they now?"

Bowing his head respectfully, the drow continued to report:

"We'll be here in about half an hour."

This distance is actually quite close, but in order not to attract attention, Carl and his team did not build a higher watchtower for reconnaissance, so the observation distance is limited.

But what puzzled Carl was how these people came here.

"Could it be that he relied on the traces left by this guy and the marks of the truck? No way? How many days have passed? The lava rivers should have made these traces disappear! "

Seeing Carl looking at him, Jialian also thought of his previous behavior and quickly stepped forward to explain: "They may be a team that came to check the situation of the Fire Dwarf Fortress and bring back the escaped slaves.

There were quite a few drow and fire genasi who escaped twice before. They haven't returned in such a long time. The people in the city probably think that the fire dwarves hid them."

After hearing Jialian's explanation, a flash of inspiration suddenly occurred to Carl's mind.

"Wait! Is that team different from you in appearance or other aspects?"

If there was no difference, Carl felt that he and his men might be able to use this information gap to trick open the fortress gate.

Because from the current situation, there is no direct channel for information exchange between the Fire Dwarf Fortress and Obsidian City.

His initial worry that "attacking the fortress without authorization might attract the fire giant" did not happen.

In fact, this kind of thing should have been asked to Galian and the others, but their rank in Obsidian City was not high, and apart from the city defense map, they did not have any valuable strategic intelligence.

After hearing what Carl meant, Galian thought about it carefully and found that judging from their appearance alone, these ordinary drow were no different from the drow that were about to arrive nearby.

The most they had was better equipment, and they all rode Phantom Horses.

"It's no different. If you can kill them, we can try to trick them away..."

"Since the group of fire dwarves can't call for reinforcements from the fire giants, why are we still being so cautious here? Just run over them! The secret passage has been dug near the fortress. As long as we are well prepared, we can break into the fortress from there!"

With a "bang", Carl slapped the machine tool next to him, scaring Zhuoer and Jialian who came to report so much that they trembled all over.

"Go inform Baine to kill all the drow that are affiliated with the fire giants, and give all their equipment to Galian!

Galian, after you get the equipment, take the required number of drow to the fortress to check the specific defense map of the fire dwarves!

Once you have finished your investigation, we will destroy the fortress!"

"Yes!"*2 The two drow stood straight and turned away.

As they informed Baine, the orc, along with his wife and construct troops, ambushed in the surrounding hills and valleys.

…

Some distance away from Bain's ambush site, a team of 12 drow were riding on phantom horses created from magic props and heading towards the fire dwarf fortress.

The two groups of people who escaped some time ago have not returned to Obsidian City yet. This made the fire giant who had originally reserved several of them to be his slaves feel dissatisfied, so he sent people to check.

When they reached the hilly area, the twelve drow dismounted one after another, intending to take a rest here and replenish their strength.

The terrain around Obsidian City is always changing, as the flow of lava can be different every three or four days.

One of the drow in the team had been to this area before. At that time, there were no hills or valleys here, just a flat lava wasteland.

"Hey! Look around here. If someone were to ambush a group of people here, all it would take is one volley of fire and we would probably die here!"

With a slightly teasing tone, a drow pointed at the place where Bain was ambushing and joked.

Bane, who was hiding nearby by melting into the stone, was startled when he heard this, and then suddenly walked out of the stone where he was hiding.

"Who is it?"

This sudden change immediately aroused the vigilance of the drow, but when they picked up their weapons and prepared to act, Baine suddenly fled in the direction they came from.

Just as these drow were about to summon Phantom Horses to chase after them, a group of things surrounded by white mist suddenly fell from the sky.

That's nitrogen that's been compressed and frozen into a solid state.

When these things are fired from the muzzle of the construct, they begin to absorb the surrounding heat frantically.

The alert Zhuoer first felt a little cool, and then found that a strong wind was blowing around him.

That was the strong wind formed by the confluence of cold and hot air currents, and along with it, there was more solid nitrogen.

“Bang!”

A piece of solid nitrogen hit the arm armor of a drow. When it hit the drow, it shattered into a mixture of gas and liquid, and then quickly dissipated.

The drow did not feel any pain at all, but when she was about to raise her arm to block something falling from the sky, she found that her arm had lost feeling.

She tried hard to raise her hand, and then, with a "crack" sound, her arm broke from the place where it had just been hit.

The arm seemed not to be made of flesh and blood, but some special stone statue.

The feeling of fear rolled in the chest of this drow. She tried to scream, but more solid nitrogen fell from the air one after another.

I don't know how much time passed before the shelling stopped.

The lava field that was originally glowing with a reddish glow had now completely dimmed.

Part of the underground lava seemed to be blocked by the sudden cooling of the earth, so it began to change direction so that it could continue to flow.

This has caused the ground nearby to gradually rise. It won't be long before it erupts magma and gradually turns into a small active volcano.

As the white mist gradually dissipated in the scorching heat surrounding him, Bane, who had run away earlier, came back.

"One, two, three... twelve. Hmm, it looks like no one escaped. I thought one or two of these guys might be able to get away, so I went to cut off their retreat, but in the end, all of them were wiped out?"

Counting the bodies and equipment on the ground, Bane muttered to himself with a look of regret.

He had originally thought that these drow were very powerful, but they were just like this? "Alright! Take off all the equipment before they thaw! I don't want to get myself covered in blood."

On the other side, Scorpion stood with her hands on her hips, scolding her husband.

However, her technique was quite skillful, and it looked like she often did similar things.

Taking away twelve sets of armor from Obsidian City's senior soldiers and the reins for summoning the Phantom Horse, Scorpion simply buried these fellow soldiers and then followed Bane back to the temporary base.

That afternoon, a twelve-man drow team ran towards the fire dwarf base in the distance.
