"Still haven't moved?" Lin Feng walked up to Zhan 3, who was in charge of observing the movements of the undead army, and asked.

"Leader! Since the army of the undead retreated to the Gates of Hell three days ago, led by the Alien Commander, they have been stagnant around the Gates of Hell, and there is no vision of attacking again. Battle 3 reported.

"Well, keep watching, don't let up!" Lin Feng said.

After finishing speaking, Lin Feng left the forward base and came to the Great Wall of Steel, looking at the endless snow-capped mountains in the extreme north outside the Great Wall of Steel and the dark gates of hell where thunder and lightning flashed from time to time among the snow-capped mountains.

At this time, a large area of black and oppressive undead creatures gathered in front of the Hell Gate, and even the undead dragon stayed on the snow at this time, relying on the infernal aura emanating from the Hell Gate to restore and recuperate their injured bodies.

"The Great Wall of Steel on the way to the south has been built!" At this time, Section 2, who was responsible for transporting nuclear weapons, walked over to Lin Feng, and after Lin Feng saw Section 2, he asked casually.

"Leader! The engineering robots brought by the transport ship rushed to the south of the Gates of Hell three days ago to build the Great Wall of Steel, and now it should have reached the completion stage. Ko2 replied politely with a smile.

"Well, that's good, so that the place of Hell Gate will be completely besieged, and after a period of time, the arsenal, battleship factory, and weapon factory in the sub-bases scattered on the continent of Westeros and Essos in this world will be built, and then there will be a steady stream of combat units of various levels that can fill the guards on the Great Wall of Steel, and the army of the undead will no longer be able to threaten us."

After Lin Feng listened to Ke 2's reply, his mood improved, and the depressed and angry mood of being made by the army of the undead in the past few days gradually disappeared, now the entire magical world has been conquered, and the engineering robots are also scattered on the Westeros continent and the Essos continent in this world under the leadership of the relevant authorities to build sub-bases, mine resources, and manufacture various types of combat units, as long as they survive the early stage of development, then Lin Feng has more war robot army than the huge number of undead army in front of the gate of hell in front of him.

At that time, Lin Feng felt that he could even organize an expeditionary force to expedition to the Strange Hell, but this idea only flashed in Lin Feng's mind and was snuffed out by Lin Feng.

Now as long as he guards the portal of the Gate of Hell and completely besieges these undead army here, as for the expedition to the Hell of the Strange Ghosts again, Lin Feng feels a little powerless.

And it has just occupied this magical world, and the next wise choice should be to climb the technology and develop peacefully for a while, rather than immediately turning to the hell of the ghosts.

Now Lin Feng feels more and more that the civilization level of his immortal civilization is still too low, although he has entered the category of first-level scientific and technological civilization, but the civilization index has only just broken one, you must know that the civilization index of first-level scientific and technological civilization includes 1 to 100, and the immortal civilization whose civilization index has just broken 1 is actually very weak in the first-level civilization.

Just as it is difficult for nuclear weapons to deal with more and more powerful enemies now, some powerful enemies will even be immune to nuclear weapons in the future, and the dark alloy warhead and the Godkiller No. 1 warhead may still be able to cause fatal damage to enemies below the eleventh order, but what about the twelfth order or above? The current Restricted-level weapons of the Immortal Civilization can only inflict a slight damage on these existences, but it should be impossible to deal with them as calmly as the Tenth Order and Eleventh Order.

Thinking of this, Lin Feng extinguished the idea of constantly conquering and expanding the world in his mind, the immortal civilization is actually the kind of mechanical civilization that can be developed with only enough resources, and the desire for territory is actually not so great.

Now that the abundant resources of this conquered first-level primary magical world are enough for the development of the immortal civilization for a long time.

"Leader! The scout bot in charge of detecting the Alien Hell has information coming back, so you don't need to check it now. At this time, Lin Feng, who had been staying in the forward base, said.

"Hmmm! Load the relevant intel onto the screen of the forward base, and I'll go over now. Lin Feng replied to Battle 3, and after ending the communication, Lin Feng walked in the direction of the forward base.

At this moment, the situation has eased, Lin Feng is not as busy as before, and Lin Feng is ready to develop in a low-key manner for a period of time, so although he is still interested in the information of the Strange Ghost Hell, he is not in a hurry to get it.

Returning to the forward base again, Lin Feng saw that the idle war authorities were also staying in the forward base at this time, Lin Feng looked at these authorities and nodded slightly, and then came to the main seat of the conference table in the base to watch the relevant information about the strange hell.

The basic situation of the Hell is that it has a black and red earth and a blood-red sky, the weather conditions are very bad, some places are hot and unbearable, and some areas are extremely cold hells, and the weather conditions are irregular, this moment it may be extremely dry, and the next moment it will suddenly rain blood.

The regular creatures that live in the Unoryd Hell are the corpses of the dead creatures that have invaded the world by the Unholy Hell and various other creatures native to the Unholy Hell as well.

Moreover, this Strange Hell is not only at war with the magical world where Lin Feng is located, but also with several other worlds, and the corpses of dead creatures in these worlds have become cannon fodder for the Strange Hell's outward conquest.

It can be said that the army of the undead now gathered near the gates of Hell outside the Great Wall of Steel is just one of the many invading armies of the Alien Hell.

The re-evaluation of the level of the Strange Ghost Hell indicates that the Strange Ghost Hell should be regarded as a first-level intermediate or above world, but because the Strange Ghost Hell is at war with many worlds at the same time, the military strength is dispersed, so that the undead army that Lin Feng dealt with is assessed as the strength of the first-level primary civilization army.

In terms of resources, through the exploration of reconnaissance robots, it was found that there are actually very few basic resources, which is not comparable to the number of basic resources possessed by this continent, but the Strange Hell has a lot of rare resources generated under harsh conditions, but most of these rare special resources are occupied by the powerful forces of the Strange Hell.

After Lin Feng saw the general situation of the Strange Ghost Hell, his eyes were distracted, and he was silent, and after a while, Lin Feng said to all the authorities present: "In the next period of time, our immortal civilization should develop well, develop and create more war weapons, and after a while, reinforcements from all sides will arrive one after another, so it is difficult for the undead army at the Great Wall of Steel to threaten us anymore."

Battle 3, Battle 4 and Hazelwind, you wait for the reinforcements to arrive and sit on this Great Wall of Steel, as long as these undead creatures don't break through the Great Wall of Steel and cause trouble on the continent of Westeros. ”
