The biggest danger in the underground world comes from the darkness, this is the consensus, and because of this, many races in the underground world have evolved abilities such as dark vision and infrared vision, even if they don't have these abilities, they will at least have a skill like "blind fighting", otherwise, it will be difficult to move an inch in the underground world.

And this is especially true for those rivers and waters that extend in all directions in the underground world, even with those abilities above, people still have no way to take those waters, and the darkness there is beyond their capabilities.

Langdon currently has no way to crack the seemingly bottomless darkness of the Blackwater River, so he can only develop the Blackwater River briefly.

Of course, this will certainly not satisfy him, in fact, he had already started thinking about it when he hit the idea on the Blackwater River, and by the time he and Avina made it public, he already had a complete plan.

However, there is another problem with this plan, and that is population.

Langdon had co-opted the goblins and lizardmen, and captured dozens of bear goblins, and by this time all the lords had gathered in Yuanwang Town, but all of them added up to 300 people, including 80 soldiers, and such a number would not be completed in ten years.

Langdon didn't want to wait so long, so after deciding to develop the Blackwater River, he also began to find a way to get people.

In particular, the Maas region is large, but the number of creatures is scarce, and the few intelligent populations have all been under Langdon's command, and the rest are beasts like rock lizards, and it is okay to catch dozens of them for transportation, and the rest is useless.

Therefore, Langdon decisively set his sights on the periphery of the territory.

The five dark elves were sent out, and Mihai returned to Solrenod to find the Mistress Isis to see if he could get some slaves from her.

Ibaka went to Langdon's third sister, Helena, who was born shortly apart and was close in age, and was the best of Langdon's three sisters, and the only one who had ever helped him.

The Larry brothers and Dedmon infiltrated the territory of other forces, which controlled their cities so much that they couldn't buy a lot of slaves even if they bought slaves from them, and they cost a lot of money, so the three of them only had to target the wild races that had not been co-opted by the major powers.

Most of these ethnic groups are too weak to even be slaves, so they are disliked by the major forces, and they don't even bother to recruit or arrest them.

However, they are very suitable for the current Langdon, no matter how weak the race is, as long as it is not to the point where the whole clan is crippled, it can still work, the difference is only that they do more and do less.

And Langdon has no one to work at all, and the difference is still huge.

Anyway, because of the existence of the heart of the city, Langdon's subordinates are not short of food at all, so they directly gave the three dark elves an almost impossible recruitment ceiling - 1000 people, as long as it does not exceed this number, whatever you want, even those green-skinned goblins Langdon!

Of course, even if he could recruit someone, it would be at least a month later, and Langdon didn't want to waste it.

The most powerful bear goblins were sent to dig the waterways, and not only them, but Langdon also drew a hundred people from the goblins and lizardmen to do it together, of course, not all of them went to dig the waterways.

In this era, there is no such thing as female workers and child laborers, as long as they have the strength to do it, and they are not old or sick enough to move, they can be regarded as labor.

The straight-line distance from the Heishui River to Yuanwang Town is actually not too far, less than five kilometers, and there are still some small broken stones, no big stones blocking the way, plus Langdon only wants a small river that can divert water and carry out basic fishing, and it is not too deep, so the amount of work is not so large.

At this time, the importance of the blacksmith shop was highlighted, and taking advantage of the system to build a blacksmith shop, Langdon used all the metal given by the blacksmith shop at the beginning to make shovels and hoes, which were not much, and could only make do.

These first shovels and hoes were not used to dig rivers, but to mine, of course, so that the blacksmith shop could continue to produce more tools.

Langdon's territory is barren and there is no iron mine, but fortunately there is still a copper mine, and because of the lord system, Langdon doesn't have to go to prospecting, he took less than twenty lizardmen to a place, and pointed down with his hand, "Down from here, dig!"

After more than a day's work, the mine was released.

The production of copper meant that the blacksmith shop could continue to produce tools, and the excavation of the river began a few days later.

Langdon strolled down the central street of Lookout Town, followed by Avina.

Just out of the blacksmith shop, the black dwarf blacksmith has good skills, it doesn't take long for a piece of copper ore to turn into a mine ingot and finally become a finished product, at this rate, it won't take a few days, all the workers will be able to complete the tools, and even if the dark elves bring people back, they don't have to worry about not being able to do work without tools and eat dry.

"Lord, aren't we really going to take a look?" Avina asked behind Landon.

"It's just a waterway, what's there to see, didn't I say it, you can go if you want, you don't have to follow me, don't you see Hogg just go" Langdon said leisurely.

Avina pursed her lips, but didn't say anything in the end, and honestly followed Langdon.

Because the tools are almost complete, the river channel of the Heishui River to Yuanwang Town was officially excavated today.

The only dangerous time to dig such a waterway is when the waterway is to be connected to the Heishui River, and only at that time can some things in the Heishui River have a chance to come out and make trouble.

So, Langdon simply asked the workers to dig from that side first and dig out a safer head.

The reason for this is that the Goblin Knight and the Lizardman Spearman are both in their free time at the moment, and the workers will be much safer with their protection.

It was just digging a waterway, which was much worse than the high-rise buildings that Langdon had seen before, and it didn't interest Langdon at all, but the two girls were very interested.

Hogg simply found an excuse to lead the goblin knight and ran away, but Avina was ashamed to find an excuse to stay, of course, maybe she thought it was more interesting to stay with Langdon than to see the waterway......

This matter was not only interested in the two girls, but even the lazy goblins who wanted to come to the scene were interested, so the old, weak, sick and disabled goblins and lizardmen also found various ways to watch, and the whole town was almost empty, and at this time, the streets of the town were only Langdon and Avina wandering, and it seemed extremely empty.

"When there are more people, a large group of people are working at the same time, it is considered interesting, and then they will understand what is the most glorious work. ”

Langdon patted Avina on the shoulder and said with a smile.
