In front of countless abyssal creatures, a thin layer of steel is no longer enough.

Fortunately, Gu Chen once again conducted five consecutive draws through the system, and the five draws were drawn to the meteorite alloy wall, which literally means a wall made of meteorite alloy.

Under the siege of those abyssal creatures, the meteorite alloy door failed to leave even a single scratch, which shows how strong the meteorite alloy door is.

At this time, five meteorite alloy walls were drawn.

In order to place the meteorite alloy wall, Gu Chen and the others left the steel basement again, and carried out an annihilation of the abyssal creatures within a radius of a hundred miles.

Immediately afterward, Gu Chen removed the meteorite alloy door and abandoned the steel basement that was almost torn apart.

A hundred meters away from the original stronghold, Gu Chen released five meteorite alloy walls.

The five meteorite alloy walls are very large, and after enclosing four of them on the wall, and leaving the remaining one as the ceiling, a small steel fortress is completed.

This steel fortress is about the size of a villa, the four sides and the ceiling are made of meteorite alloy walls, after completion, in order to prevent abyssal creatures from digging in through the ground, Gu Chen asked Xuan Mo to release the third soul technique ten times in a row, leaving a full ten meters of steel ground below the steel fortress.

Even if the Black Emperor descends, I'm afraid he won't be able to penetrate the ten-meter-thick steel in one blow.

The huge steel fortress was empty, but Gu Chen and the others were self-reliant, and the fourteen people cut down the dead wood within a radius of 100 meters in just two days, and they could see it at a glance.

These dead woods were selected by Xuanmo, who has a carpenter's background, and made into staircases, floors from the second to the fourth floor, and various furniture.

At the same time, with the powerful golden dragon claws, Gu Chen forcibly opened a hole in the meteorite alloy ceiling for only one person to pass through, and built a lookout platform out of dead wood on it.

At this point, a fully functional survivor base has been constructed again.

On the twentieth day of the month, the number of abyssal creatures in the Nameless Mountains had nearly doubled compared to twenty days earlier.

And Gu Chen also took out the armed drone rewarded by the system, and told the rest of the people the role and use of this armed drone.

Luo Chen and the others have unconditional trust in Gu Chen, and it is the kind of trust that they don't care about.

And Gu Yuena looked at him with a puzzled face, after all, as the same dragon king, she knew very well that the dragon god did not have so many treasures.

However, the IQ of a woman in love is almost zero, and although Gu Yuena did not say it explicitly, she has obviously fallen.

She was just confused, and didn't say much.

With the help of armed drones, powerful control forces suppress nearby abyssal creatures.

If there are fewer abyssal creatures outside the survivors' base, they will go out together to clean up the abyssal creatures, and Gu Chen and Gu Yuena absorb the energy of these abyssal creatures.

If the number of abyssal creatures is too large, resulting in an abyssal tide, or an abyssal bomb swarm appears, then Gu Chen will release an armed drone to strafe the abyssal bomb swarm and suppress the advance of the abyssal tide.

The flight speed of the armed drone is so fast that even the Abyss Bomb Bee can't catch up, and the firepower of the armed drone is so fierce that it has become a nightmare for the Abyss Bomb Bee.

I'm afraid that these abyssal bomb bees killed by the armed drones, after returning to the abyss plane and resurrecting, even if they come to the Douluo Continent through the space tunnel, they will not dare to find trouble with this armed drone again.

Since the dead trees within a hundred meters were all cut down by Gu Chen and the others, General Meng, who was secretly protecting, could only observe from a hundred meters away, and even he, who was a Title Douluo, was shocked by the efficiency of this armed drone in killing abyssal creatures.

He couldn't wait to get this armed drone and put it to work for the Great Wall Guardian Army.

It's a pity that his mission is to secretly protect Gu Chen and Gu Yuena, so he can't come forward. But this form obviously doesn't need his protection anymore, right?

After an abyssal tide was repulsed again, General Meng returned to the barracks in half a day, found the commander, and told the commander Gu Chen about the powerful weapon of armed drones.

The commander pondered for a long time before he said, "That is his own property, and we have no right to interfere." At the end of the half year, you can ask him to buy it, but you can't force it. ”

"Yes!" General Meng retreated and returned to the Nameless Mountain Range to secretly observe Gu Chen and the others.

The second month ended quickly, and before leaving the steel fortress, Gu Chen and his party first completely destroyed the watchtower outside the meteorite alloy ceiling, and then Gu Chen took out the piece of meteorite alloy that he had deducted before, and installed it in the position of the hole.

Fourteen people rushed to the exit after observing that the survivor base no longer had any loopholes for strangers to enter.

Due to the abyss tide, even if Gu Chen and the others did not snatch other students this month, their scores did not drop but increased, and even more than three times the original.

After exchanging the resources needed for the next month, Gu Chen returned to the cadet camp, at which point he found that the number of surviving cadets had become even more scarce.

Turning the score bracelet, it was clear that there were only two hundred and thirteen surviving students left at this time.

At this time, the rest of the surviving students also seemed to realize the seriousness of the matter, and the leaders of some small groups jointly initiated a so-called survivors' meeting.

These were also the things that Gu Chen only knew about after the members of these small groups came to invite Gu Chen to participate.

"Survivor meeting, kind of fun." Gu Chen touched the black hair of his shawl and said with a smile.

The place where the survivors' meeting was held was in the middle of the cadet camp, and a few tents were removed to make room for an open air.

The bosses of these small groups did not put on a show and occupy high positions, but arranged more than 200 chairs around an open space.

Gu Chen and the others came here with great interest, and at this time, most of the chairs were already seated, and fourteen people found chairs to sit down.

At this time, the leader of a small group walked out of the students, came to the open space in the middle, cleared his throat, and said, "You all be quiet, as you know, the number of abyssal creatures has suddenly increased for some reason, and our survival rate has been greatly reduced. ”

"We're not just competitors, we're the same kind, we're the same human race, instead of fighting against that damn abyssal creature, we're doing the opposite, we're starting infighting, isn't that like a word?"

"Why don't we form a big team of more than two hundred people, divide labor and work together, and jointly resist the invasion of the abyssal tide, what do you say?" The leader of the small group asked loudly.

At this time, a hundred meters away, a Titled Douluo General saw all this at a glance, he stood on the high wall, looked at the other general beside him, and said with a smile: "It's only been the second month, and they have already comprehended." Do you remember when the children of 50 years ago understood this truth? ”

"Seems like the eighth month, right?"
