The world of Azeroth, the Eastern Kingdom, in the midst of the Dark Swamp.

In the originally peaceful swamp, a huge stone gate with a height and width of several hundred meters suddenly appeared, and a huge statue of the same height as the stone gate was erected on both sides of the stone gate. In the middle of the stone gate, there is an orange-yellow light curtain with a diameter of 100 meters, which is a portal for teleportation across the world. This gate is what connects Azeroth and Draenor, and is known as the Dark Gate.

As for this side of the world of Azeroth, it was built by Medivan, the guardian possessed by the Burning Legion boss Sargeras, so the natives of the world of Azeroth do not know about this portal yet.

On the other side, the world of Draenor is different, and the Iron Tribe, led by Grom Hellroar, are entering the world of Azeroth through this portal. After surviving the discomfort of interstellar teleportation, these orc forces are now surveying the vicinity, logging in the nearby woodlands, and building a stronghold in front of the Dark Gate.

When this stronghold is completed, they will be able to rely on the stronghold to defend and begin to radiate to the surrounding area, and they will also be able to ensure that the follow-up troops in the rear can pass through continuously. The number of orcs who have passed through the darkness is still too small, and they must first establish themselves in this world, and then wait for all the troops to teleport over, and then conquer this world. So, now is not the time to engage with the indigenous people of this world.

And a week has passed since they came to this world, and after this period of hard work, they have carved out more than twenty camps on this land, most of which are still under construction. After all, after a few days of teleportation, nearly 100,000 orcs have been teleported from the Draenor world, and if it weren't for the fact that a large number of materials were transported at the same time, the number of people who had been teleported over now would be close to 150,000.

But unbeknownst to these orcs, their existence had been discovered, and Li Nan's men had already entered the world of Draenor through the Dark Gate.

When Li Nan took Skye to Azeroth for testing, and then learned of the orc invasion from Nova. It didn't take long for five stealth transport planes to take off from the harbor camp in Thorn Valley. There was an adjutant in charge of Draenor's affairs, as well as 100 Marines, 100 Medics, 100 Marauders, 100 Reapers, 90 Ghost Agents, 5 SCVs, and 4 Astral Explorers. As for why transport aircraft, and not more powerful battlecruisers? That's because of the size of the teleportation light curtain in the Dark Gate, which is only a hundred meters wide, so the battlecruiser can't pass through the Dark Gate at all.

The 5 stealth transport planes in a fully loaded state quickly came to the sky above the Dark Gate in an invisible state, and then quickly teleported through the Dark Gate from the air. Although the stealth function of these planes was briefly taken offline during teleportation, the force field generator in the aircraft was maintained all the time, and the stealth function of the defense force field was not affected by teleportation, so the five transport planes remained invisible.

And through the camera of the transport plane, you can see the huge tribal base behind the dark gate, and the dense number of orcs waiting to be teleported. There are no less than 300,000 orcs in the range captured by a few transport planes through the camera. As the overlord of the complete Draenor world, the number of orcs is still very large.

The planes didn't stay long, and then immediately flew off into the mountains in the distance. In this Draeno world, just by looking at the landscape, you can confirm that the Titans have visited here and transformed the landscape here. However, it may not be possible that this planet is not suitable for breeding new Titans, so there are no observers left here.

Finally, the transporter came to the left of Shadowmoon Valley and landed in the middle of the group separated from the rest of the map. This area is used to separate the two large lands, and the area stretches for tens of thousands of square kilometers, and it is a place where life is extinct. This kind of tens of thousands of meters high mountains, even most of the flying creatures can't cross it, and even the monsoon can completely block it, so this is also the reason why the climate of each land is different in the world after the transformation of Titans, and even the climate between these lands cannot affect each other.

And although the living conditions in these mountains are very poor, and they can be regarded as a forbidden area for life, as a force in the interstellar era, whether it is the humans of the Tyranid Empire or the star spirits, it is not very difficult to build bases and colonies in such a harsh environment.

Of course, Li Nan still likes this behavior of the Titans very much. The main reason is that in these tens of thousands of square kilometers of mountains, it is very easy to hide troops. Most of the mountains around Mogaolei have been completely hollowed out by Li Nan, and there are even thousands of battlecruisers hidden inside, and they are of all ranks. At the same time, Li Nan has also created a lot of the purifier fleet of the Star Spirit Clan, and of course this is also the main thing to do in the past ten years.

And with the landing of the transport plane, the troops transported inside also came out of the cabin. The first is the engineering robot SCV, one of the SCVs lifted a box more than one meter high from the cabin, and then began to take out parts from the inside and began to assemble them quickly, this is the fifth additional standard building in the latest front-line base, the force field generator, and the other four SCVs began to build the four major pieces of the front-line base. The rest of the infantry dispersed to the perimeter and began to guard and defend.

After ten years of development, Li Nan's technology has still made some progress, such as the five standard buildings of the front base, the force field generator only takes 5 minutes to complete the assembly, and the construction time of the other four pieces has also been reduced from one hour to 30 minutes, and the construction time has been reduced by half.

In less than two hours, a front-line base capable of accommodating the lives of five hundred battle elves, including the military area and living quarters, had been fully built, and the entire area was covered with a defensive force field, so nothing could be seen from the outside. Of course, these buildings are mobile, and their job is to build an underground base, and when the underground base has developed enough space, this base will be moved underground to serve as the main base of the world of Draenor.

At this time, the entire base has been protected by the alloy wall, and the sentry guns, defensive missiles, siege tanks, and these defensive facilities and machinery have been arranged on the wall in large numbers. At the edge of the living quarters of the base, a warehouse was built at the same time, and in the warehouse was a large hole that had been dug down, which would be the construction port of the underground base.

A total of 490 battle goblins in Dingyuan, 100 of them were left to put on various equipment to defend in the base, and the other 390 have entered the space of the underground construction site for construction, and the prototype of this underground base can be completed in about 2 or 3 days.
