After Maxing out all Classes

.
He saw the dwarf leader standing by the stone stool and waiting for him.
As soon as he saw him, he said anxiously, “ah, you're back.”

Robb asked, “how is it going?”

The dwarf leader said, “the monsters haven’t launched an attack yet.
It's just that a small group of scouts are close to our underground village.
Our race is very experienced in underground war, so we easily defeated the small group of scouts without letting any of them escape.
However, if these scouts don't go back, the demon king will definitely be on guard, and there will be more scouts coming later.”

Robb, “Okay, I happen to need the monsters to cooperate with my movie.
I’ll take this opportunity to go down and have a look.”

The dwarf leader took a look at the sewer lid beside him, and his face was a little embarrassed.
“You want to go down? But…
The sewer is now full of dirty water and stinky…”

“It doesn't matter.
I don't mind the stench!” Robb said with a smile.

The dwarf leader laughed happily and said, “humans are good in this respect.
They can be clean when they are clean, and when they are dirty, they can also be dirty.
They are not like elves who can't bear any dirt at all, and they are not like us who don't like to be clean.”

Humans were the most flexible of all races.
This might be the reason why humans could occupy the largest area of the continent.

The dwarf leader opened the sewer lid and jumped in.

Robb fetched the “goblin disguise” from a distance and didn't wear it for the time being.
He held it in his hand and slowly climbed down the stairs with his other hand.

Since the sewer was put into use, Robb had never gone down.
As soon as he went down, he smelled an unpleasant odor, which was the combination of shit and urine, very unpleasant.

Robb couldn't help but pinch his nose and said, “Wow, the smell inside is really bad.
It's spring now.
I dare not imagine it during summer.
It seems that the sewer needs some ventilation, or the stench in summer may cause an explosion.”

The dwarf leader said, “explode? How will that happen?”

Of course, the dwarf leader didn't understand this kind of chemical knowledge.
Robb didn't explain the principle, but said directly, “in a word, you should find a few places that can be ventilated, dig through to the upper ground, and make a vent.
The vent should be placed in a far place to not let out poisonous gas into the town.”

The dwarf leader wrote down Robb's request.

The two of them walked in the sewer for a while and arrived at a fork.
This was the place where the monster army dug out the sewer.
Now the fork was sealed by a heavy iron door.
It was specially made by the dwarves to separate the sewer from the village.

The dwarf leader pushed open the big iron door and went in, followed by Robb.

Then they walked through a long and dry tunnel.
Instead of the unpleasant smell of sewer, they smelled hot, steel and fire works.

After turning a corner, they arrived at the village.

A few months ago, this place was still the territory of the crypt lord.
There were many poisonous mosquitoes and beetles crawling around, but now, it had become a lively village underground, and a relatively large underground factory.

The cave was surrounded by strange small caves, and there was a dwarf living in each of them.
In the middle of the cave, there was the public worksite of the dwarves.
There was a huge factory, with red furnaces, huge hammers, and big gears.

A half built steam tank was tilted to the side, and a group of dwarves were adjusting its steam engine.
Seeing Robb, the dwarves jumped up together and said, “ah, grandmaster blacksmith, welcome to the dwarf village.”
