Xiling Chen did not go back to the base of the Purple Moon Guild directly, but went to the place where the sea was sleeping, and he wanted to tell the zombie maid the news.

This space gate has something to do with the seal, and although he doesn't know a lot of the situation, he can guess some based on the current information.

The seal is generally fine, but there should be some loopholes.

The Demon Tide Monster, that is, the Chaos Monster that the zombie maid said, took advantage of these loopholes, whether it was the previous red space crack or the current space door, it all showed that there was a little problem with the seal.

Of course, there are other possibilities, such as this time it has something to do with the Annihilation Sect.

After hearing this, the zombie maid just nodded and said, "Fortunately, the situation is not that serious, this kind of spatial gate also appeared in the era of the Undead Empire." ”

"But if the space door is not closed, then the monsters will continue to appear." Xiling Dust Road.

"No way." The Two-Faced Monarch shook her head and said, "Although we know about the seal, we don't know exactly where the seal is, but my idol should know something, but she hasn't woken up yet." ”

This girl refers to the sea that is still sleeping.

"Well, then I'll go first, and if there's a situation we'll contact each other." Xilingchen said.

Back to the Purple Moon Guild, he told a few people in the guild about this matter, although the space gate temporarily has two empires and various top forces in charge, if there are really a large number of monsters emerging from it, it will be difficult to defend with the current defensive team.

And the space gate can't be sealed, so this matter is tricky.

"Do you have any plans?"

Su Miao'er looked at the young president who was thinking in front of her, she believed that Xilingchen had a way, and Xilingchen did have a way, but it was not for the space gate, but for the guild.

"Let Sky City find a way to lift into the air, the defense facilities will not be built for the time being, I have a feeling that the Black Dragon Plain may be very chaotic after that." Xilingchen said.

"Then I'll arrange it." Said the android girl D-5226.

……

The formation that Xiling Chen arranged near the space gate could delay the chaos monsters, but it couldn't last long, and the major forces also understood this.

So the battle now, that is, to resist it, to buy time for the team in the rear.

If it is lost, then the first to face the attack of the demon tide will definitely be the two human cities, so the two empires will definitely have to buy enough time for the city to enter the battle state, and the other forces on the Black Dragon Plain and the continent will naturally not just look at it, everyone has their own plans.

Time passed day by day.

A week later.

The formation arranged by Xiling Chen lost its effect, which was already within the calculation of the major forces, and after the formation lost its effect, the legendary powerhouses of these forces made a move, and they protected their respective teams and retreated.

Although the space door has been open, the chaos monsters that come out of it are not intelligent, although the number of these monsters is large, they do not know how to cooperate.

Even if there are legendary high-level units in the monsters, they can be killed quickly by joining forces with the legendary powerhouses of these top forces.

This scene on the ground was naturally seen by the Purple Moon Guild.

Xilingchen's flying villa is watching from the air, although the villa is his laboratory, but after such a long time of transformation, the villa has also become a small aerial platform, with little combat ability, mainly responsible for monitoring.

Intelligence is very important, and there are no satellites on this planet, so it can only be monitored with flying villas.

In this way, if any monsters come towards the territory of the Purple Moon Guild, the villa can also serve as an early warning.

In short, the situation that can be taken into account, the guild has already made the best preparations in advance, and now it is up to the situation after the Black Dragon Plain, if the cities of the two empires can block the attack of the demon tide, then the Purple Moon Guild will have time to develop, if it can't be stopped, it can only run away.

Fortunately for the time being, after the major forces retreated, the monsters that came out of the space gate began to wander around, and these chaos monsters did not attack the nearest city as soon as they came up.

But this situation lasted only two days.

On the morning of the third day, a group of legendary-level chaos monsters walked out of the space gate, and the aura emitted by these monsters could be felt from a long distance, ranging from level ninety to ninety-nine.

As soon as these monsters appeared, they split into several groups, and the chaos monsters that gathered near the space gate also began to act.

Half an hour later, three powerful magic tides formed.

These three demon tides all have ninety-nine level chaos monsters, and there are more than a dozen legendary units, and the number of ordinary monsters is between five thousand and ten thousand, which is quite terrifying.

Two of the demon tides are targeting the cities established by the two major human empires in the Black Dragon Plain, while one of them is heading towards the guild's side!

That's right!

According to the temporary path of this monster, it is estimated that it will be able to reach the Purple Moon Guild in one day.

"There's nothing on our side that's attracting chaos monsters, is it?" Moonlight Virginia asked suspiciously, standing on the Flying Villa.

Xi Lingchen thought for a moment and then shook his head and said, "It's nothing, it should be just a coincidence." ”

In fact, there is one thing, and that is the space spar that was seized before.

However, Xiling Chen didn't think that the monster was aimed at the Purple Moon Guild, it should be just a coincidence.

His guess was right, this monster changed direction after advancing for a few hours, rushed towards the lair of one of the forces in the Black Dragon Plain, looked at the map, and found that this strength was quite famous, called the Beiwu Chamber of Commerce.

The Beiwu Chamber of Commerce started by manufacturing weapons and equipment, and has developed in the Black Dragon Plain for more than two hundred years, although it is not a top force, but it is also close.

"Shall we help?" Moonlight Virginia asked.

"No, no."

No matter what the other party said, they have also developed in the Black Dragon Plain for more than two hundred years, and they still have some friends, and the Purple Moon Guild is not familiar with them.

Leaving a few maids to watch, Xilingchen and Moonlight Virginia returned to the guild base.

The guild base is busy because of Xilingchen's plans, and Sky City is making final preparations before takeoff, because many facilities have stopped construction, so now just let Sky City take off, which can still be done.

His idea was simple, that is, to fly first, and the later construction was completed in the air.

As long as there are legendary powerhouses in charge, there is no need to worry about defense.

A sky city can't accommodate so many people from the Purple Moon Guild, so after this sky city takes off, the construction of a second sky city will begin.

There is no shortage of resources for the time being, and some technical problems have also been obtained from the library on the side of the sea underworld, so now is the time, as long as there is time, the Purple Moon Guild can make Sky City take off.
