This swampy terrain also seems to be the product of goblin experiments, Xia He's aircraft emits induction waves, and can detect that there is a huge void under the swamp, just like the underground world of the main world.

It is estimated that it is also a dangerous place, but in the swamp, there is still a road, and it is a railroad track built by early goblins.

Humans have never been here, so Xia He sent a robot to dismantle the railroad tracks, and he needed a lot of metal. The metal he brought from the main world was far from enough, all he brought were special alloys, and he basically didn't bring much ordinary steel, hoping to replenish it in this world.

It's a pity that this world is different from what I thought, and there is no goblin city in the place where it comes.

If there were a city, countless steel could be torn out, and in the goblin city, there was always an astonishing amount of metal.

However, there are no goblin cities in this vicinity, which will limit the development of Xiahe. The prospecting robot has also been released, and Xia He is estimated to have no good results.

Because if there was an iron mine nearby, the goblins would have discovered it a long time ago, and there was a coal mine here, and if it was found, no matter how small the iron ore was, it would be mined and refined on the spot.

On the side of the human stronghold, Xia He also sent people over.

The necromancer's magic tower is only three floors, which is very pitiful, and of course it can't communicate with the undead world.

Xia He didn't let people build any new magic towers, but went to the eastern lake to choose a site.

The large lake in the east, the water of the lake is clear, and the submersibles who repaired it found that ten miles away from the shore, the lake water became very deep, and the deepest depth may be more than two miles.

Not surprisingly, some small worlds have particularly deep lakes, probably on geological fissures in ancient times.

However, the lake is so deep and vast that it is necessary to build ships, but not too much. Now that Xiahe has no metal, it has to be solved first, otherwise nothing can be done.

"Teacher, we have found a new ore, which is obsidian. "A magician ran over and reported to Xia He.

Xia He doesn't have much nature, obsidian is one of the best materials for building magic towers, much better than artificial stone made from cinders. However, this thing is widely distributed, and there is no problem of lack of quantity. The world is so big, and the goblins don't mine it anymore, so the amount of obsidian will be very impressive.

But there was always a good thing, so he ordered that the obsidian be mined first, and that a good site be chosen by the lake to build a city.

This side of the mine is not conducive to life, it just exists as a large-scale alchemy factory, and it can also establish coordinate points, relying on the huge coal mine, there is no need to worry about consumption, the next time the world channel is opened, Xia He will be reversed, and the resources on this side will be directly used.

However, if this world passage wants to be opened for the second time, the safest thing is two years later.

If Xia He wants to go back, he needs to open a portal alone, which costs a lot of money, and he can only pass alone.

His advantage is that he can contact Lucifer, and if he wants to go back, he can supply the coordinates and go directly to the safest place in Cape Storm.

This is an advantage that other expeditionaries do not have, and Xia He is not too worried about problems on his side, he can return at any time.

He also gained something from going to the technological world of Snowvis, and he had a lot of experience in how to travel between the two worlds.

As for the cost of the teleportation array, he now has two veins of magic primordial stones in his hand, and he can't afford to spend it.

The information of the iron mine soon came back, and more than four hundred miles north of the swampy area, there was an iron mine, but there was a small town nearby, and there were many goblins in it.

And there are only narrow railroad tracks in the swamp, and the transport capacity is not good.

Another location is on the north shore of the great lake to the east, and about 1,200 miles from the west shore there is an iron mine, although it is farther, but it is much easier to transport the ore back from the water.

If the lake is safe, Xia He can build huge wooden boats to transport ore back, and send machines to complete this task, even if it is risky, at most build some small warships to protect the ships.

After the news was confirmed, Xia He ordered to continue to dismantle the railroad tracks in the swamp, and then build boats to prepare for the north shore of the Great Lake. The number of demonic goblins over there is even larger, with a medium-sized city.

Although the goblins are demonized, the current wisdom has not yet degraded cleanly, and it is not easy to win hundreds of thousands of goblins.

The flying battleship passing by at high altitude also aroused the alarm of the demonized goblins, which means that there are at least legendary-level goblins in that city.

Xia He didn't have much to do, so he had to give priority to the resources here to build warships.

This inland giant lake can completely accommodate giant warships at sea, but Xiahe now has high-grade materials, and the battleships don't have to be built so big, and they can accommodate enough formations.

The alchemy factory began to produce day and night according to the drawings given above, and the address by the lake was also chosen, directly following the appearance of Sun City, except that the city was closer to the shore.

All the magicians threw themselves in, prioritizing the construction of ports, dockyards.

Abigail was not good at making it, so she led her soldiers to the southern forest to see if there were any villages with goblins hiding in the forest.

It took several months to build a ship, and Xia He was building a city by the lake at the same time.

He started work according to the Daomen standard, and most of the large vehicles passed, leaving a few for the alchemy factory. Various machines were manufactured on a priority basis, and a complete renovation project was carried out around the lake.

First of all, to deal with the bottom of the lake, the Xia River needs a deep-water port, and the depth of the lake is only a few meters. This is a huge amount of work, and if there is no underwater machinery, it is not known how long it will take to rely on manpower. However, the quality of the water in this lake is quite good, and there is no radiation.

The silt at the bottom of the lake is cleaned out and treated with technology to be used as high-quality soil, which can be selected on land and arranged as farmland.

The underwater underneath the harbor is all reinforced by magic, and there are hidden caves, which are actually warehouses for underwater golems.

In Xiahe's naval system, there are various underwater puppets that can cooperate with ships in battle.

The entire quay area, dug several meters deep, flattened the terrain, and then covered with cinders, which were fused into artificial stone. There is a large amount of cinder in the original coal mine, which should have been a fire when the goblins were still in business, and the pit within a radius of thousands of kilometers burned out.

It is just used to transform the surface, the geology of the lake is not very good, at least a few meters above the surface is not suitable for building houses.

Xiahe is to dispose of all the silt and solve the problem completely.

Behind the pier is the city, and a few hundred meters behind the planned city walls, tall buildings have risen. In front of the building is the parade ground, and there is a high platform on the left. The high octagonal platform is built around the inner ring stone tower. The exterior is all wood, and the main structure of the obsidian inside is not visible.

This high platform is more than 20 meters, and there is a flagpole on it, and the huge flag on the flagpole flies without wind.

A bright red fire crow pattern, lifelike.

Xia He gave priority to erecting the flag, this battle flag is used to protect the city, and the Daomen equipment that Freya personally refined in Storm Corner is all provided by Xia He himself.

The fire crow on the battle banner can be summoned, but it is not a one-time thing.

Under this high platform, the formation nodes of the entire city will be built, and the battle banner will be tempered by the city's large array every day, and sooner or later, the fire crows above will become extremely powerful.

This day will not be too long, as long as Xia He is willing to invest.

When the fire crow grows up, if Xia He doesn't meet the level standard, he can also challenge the goblin demigod.

Xia He was not originally this plan, but when he found that this world was so rich and did not have any great power, he immediately changed his plan and decided to upgrade his battle banner. This is the fastest way to gain combat power.

But if you can win this world, what is it to invest a hundred times the resources?

Xia He knows that time is running out. If you don't seize such a good opportunity, it may belong to someone else. He has not completely severed the relationship between this world and the main world, and theoretically speaking, this world can still be discovered.

Once discovered, he simply doesn't have the strength to have it alone.

Not only did he erect the banner, but he also made a chart of burning seas, which he laid on the docks, so that he could turn the city into a sea of fire if needed.

This burning chart is not to protect against goblins, but to prevent the world from being discovered and other people invading.

On this day, Xia He combed through the entire city's underground array, and when he was sure that nothing was missing, suddenly more than a dozen underwater puppets cut off contact.

To the east of the docks, a giant monster is approaching at a rapid pace.

As soon as Xia He turned around, he soared into the sky, and flew onto the high platform, he stood under the battle flag, stroking the flagpole with his hand, and rejoiced in his heart.

I need powerful creatures to sacrifice the flag.

The fire crow on the battle banner needs to devour powerful souls to stimulate spirituality, otherwise if you want to speed up your growth, you can only continue to invest in jade, or increase the consumption of magic raw stones more luxuriously.

On the water in the distance, a waterline suddenly broke, and in the blink of an eye, the surface of the lake seemed to explode, and huge waves surged towards both sides.

Xia He patted the flagpole and heard a crisp and loud voice on the battle flag.

Rise!

The crimson figure pounced out, and in an instant it was on the surface of the lake. The Divine Fire Crow swooped downward, the third foot of its abdomen opened, and it grabbed fiercely. A huge figure was caught out of the lake by it.

Those who noticed this scene can now see nothing.

The temperature on the body of the Divine Fire Crow was too high, and a huge steam mass was formed in an instant, and the steam burned again, exploded, and spread, and it was like a sun rising on the water.

Everyone was distracted, except for Xia He and his war Taoist.

The chirping of the fire crow echoed in their hearts for a long time.

What the Divine Fire Crow grabbed out of the water was an old turtle with giant spines on its back, and the claws of the Divine Fire Crow directly penetrated its back shell, which was harder than steel.

Legendary creatures have fallen meaninglessly.
