After digesting the merits bestowed by the barbarian world, Ye Zan and his party divided into four teams and began to completely wipe out the remnants of the demons outside the sky. Whether it is Ye Zan who has a war fortress, or Casaro and others who are in groups of two or two, it can be said that it is quite easy to deal with those extraterrestrial demons now.

Not to mention that there is a war fortress on Ye Zan's side, Casaro and the others are also at the peak of the law level, and they also have the merit power bonus of the barbarian world. Although Casaro and the others did not choose to become gods and let Ye Zan help filter out the elements of the gods in the merits, they are still people of great merit who are favored by heaven and earth.

Therefore, with the Extraterrestrial Demons who have assimilated the origin of this realm, Karosa and the others will not only not be suppressed by the will of the origin, but will also receive additional preferential treatment. After all, although the origin of the world was assimilated by the demons outside the sky, making the law of power biased in favor of the demons outside the heavens, the will of the origin still had the instinct to choose the interests and disadvantages.

With such an advantage, the three teams composed of Casaro and the others can also be said to be like a bamboo, constantly clearing out one after another extraterrestrial demon strongholds along the way. Of course, there is another very important reason why it is so smooth, and it is needless to say that the Zerg has continued to suppress the evil demons outside the sky before.

Due to the large area of the savage world, even if Ye Zan had a war fortress, even Casaro and the others could fly, but the extermination of the demons outside the sky still lasted for nearly half a year. In fact, in the past half a year, they have not really fought against the demons outside the sky for a long time, and most of the time has been spent on "hurrying".

In the past six months, one Extraterrestrial Demon Stronghold after another has been cleared, corpses have been thrown on the ground to be devoured by insects, and mobile fortresses have been left in place. It's not that Casaro and the others can't control it, it's mainly that the flight speed of the mobile fortress is not faster than their own, but it consumes a lot of energy.

Therefore, although Casaro and the others have always wanted to have a mobile fortress that truly belongs to them, they will not seem so impatient. Moreover, Ye Zan had promised before that when he handed them over to the mobile fortress, he would also help them make some modifications to the mobile fortress. After all, they wanted a mobile cave, not a crude war machine.

Over the south coast of the savage world, a massive fortress of war hung steadily in the sky, as if it were just a painting, without a trace of trembling. Several streamers flew from afar, and when they came to the outside of the war fortress, they were none other than Casaro and the others from the other three teams.

Although they have experienced a "long journey" and many fierce battles with the demons outside the sky, the appearance of Casaro and the others is still the same as before, and there is not much fatigue between their eyebrows.

Ye Zan took Casaro and the others into the fortress, and the group gathered in the "battle room" and watched what was displayed on the screen.

"Before, we basically defeated the demons outside the sky one by one, and the Zerg has always maintained their suppression, so it took almost no effort to win. But then, what we have to face is no longer a small stronghold, but a real war, a decisive battle against the remnants of the demons outside the sky. Ye Zan pointed to the content on the screen and said to everyone in the conference room.

At this point, an island in the deep ocean is displayed on the screen. The island is not small, about the size of several war forts, and is surrounded by steep cliffs, and there is hardly any place to land from the sea. At the same time, most of the trees on the island have been apparently cut down, and mobile fortresses are being parked in the vacant space.

Obviously, the Outer Heaven Demon is not a fool, and in the face of the constant harassment and siege of the Zerg, he will not really stick to the same place. It's just that those extraterrestrial demons stationed in the depths of the interior have no chance to escape to the sea under the siege of the Zerg. Only the Extraterrestrial Demons who were stationed not far from the sea had a chance to break through the encirclement of the Zerg and escape all the way to the depths of the sea.

In addition, after these alien demons escaped to the sea, it was clear that they had strengthened their bond with each other, until they finally united as they were. Although they may have belonged to different forces, when faced with the same situation, how can the grievances between the forces be better than life and death.

As a result, in this not very spacious island, there are now sixteen mobile fortresses. In addition, although not every mobile fortress is bound to have a law-level extraterrestrial demon sitting in the town. But even if it's half and half, there must be at least eight law-level powerhouses here, and there are even more extraterrestrial demons at the Yuan Infant and Yuan God levels.

That's why Yeazan would say that it was going to be a decisive battle.

"They were quite clever enough to escape to such a place, and they didn't seem to be affected by the Zerg Lord. Lin Mumu looked at the several mobile fortresses on the screen, and just by the comparison of the appearance of those mobile fortresses, he could guess that the other party's life during this time must be much better than the ones he had seen before.

"It's true that although the Zerg can breed aquatic insects, this place is too far away from the mainland after all. "Ye Zan has pervasive monitoring methods, and he is naturally more aware of the situation here.

Although the Zerg are powerful, they are not omnipotent.

According to the needs of the environment, the Zerg can adjust the genes and reproduce the insects that meet the requirements. However, they can only breed bugs that favor one aspect, and it is impossible to breed all-round bugs. Therefore, when they are on land, they can breed bugs suitable for land warfare, and when they are at sea, they can also have bugs suitable for naval warfare, but it is difficult to do both.

Or to put it another way, just like the bonus points in some games, the free points of the Zerg are basically a fixed value, and the key depends on where these points are added. For example, there are ten points: if you add ten land and zero water, it means that the land battle is extremely strong, if you add ten water and zero land, it is pure aquatic insects, and if you add five land and five water, then you can take both, but it also means that neither aspect is outstanding.

Therefore, if the Outer Heaven Demon escapes to the deep sea island, although it will still be harassed by the Zerg, it is really just harassment. It is so far away from the mainland, even if the Zerg have flying insects, they have almost no combat ability after flying from the mainland.

Of course, the Zerg side is also wise, and now they have occupied some of the surrounding islands, but they can use those islands as aircraft carriers.

It's just that the island chosen by the demons outside the sky obviously put a lot of thought into it, and there are almost no real "islands" around, at most there are just some "reefs". On those islands and reefs, there are almost no resources, let alone directly moving to make insect nests, and even the flying insects are difficult to find enough food to rest.

All in all, despite being at war with the Zerg for the first time, the Outer Demons still managed to choose a good place to deal with the Zerg with their experience and wisdom.

"This also means that the state of the Outer Heaven Demon at this time, whether it is a person or a mobile fortress, is much better than what we encountered before. Therefore, in the next battle, everyone can no longer have any idea of underestimating the enemy, and even be prepared for a hard battle. Ye Zan then reminded everyone.

Ye Zan and them, including Casaro and the others, had dealt with the extraterrestrial demons before, and they had all been tortured by the Zerg and were about to collapse. Not only is the various damage to the mobile fortress, but the demons outside the sky inside are also extremely consumed, and the mana may be relatively easy to recover, but there is no other way to rest the energy. Therefore, when dealing with those extraterrestrial demons, Ye Zan and their side were quite easy, even if they were facing opponents of the same level.

But now, the extraterrestrial demons on this island are not only united, but they are still in good shape. In the face of such an enemy, if Ye Zan and their side still have the same idea as before, it is really possible that the gutter will capsize.

"Well, we'll take care of that. Cassalo and the others nodded in agreement.

"Okay, then next, let's assign the task ......" Ye Zan said, calling up more information on the screen, all of which were enemy intelligence collected through monitoring.

On the side of the demons outside the sky, when they saw a huge war fortress appear in the sky, they naturally reacted quickly at this time. Through communication tools, they sent a message to the war fortress, asking if the comer was a reinforcement from their own side, and at the same time did not relax their vigilance at all.

And as the mud cow entered the sea with the information asked, the evil demons outside the sky naturally understood that this was obviously not reinforcements from their own side. Although they couldn't figure out why the enemy had a war fortress, now that the facts were already in front of them, what could they do if they couldn't figure it out.

The sixteen mobile fortresses lit up their defensive fields one after another, and rose into the air and gathered together, forming a flying object that was not inferior to a war fortress like an assembly game. And with this convergence, the respective defensive force fields of the mobile fortress quickly seemed to merge into one, and it seemed to be much stronger than the defense of the individual when it was separated.

After Ye Zan received the information from the demon outside the sky, he did not pretend to be reinforcements to deceive the other party, but directly threw the information aside. After all, the Outer Heaven Demon is not a fool, and he doesn't think that if he replies a false message, he can really let the other party let him enter the island defenselessly.

Therefore, from the point of view of Ye Zan , this decisive battle is destined to be a head-to-head showdown.

By the time the mobile fortresses had risen into the air and converged their defenses into one, Yezan's side had already finished their battle meetings and launched the first wave of artillery attacks against the demons outside the sky.

Those levitating turrets like giant eyes gathered on the side of the fortress to face the enemy, and a stream of cannon light sprayed out from the muzzle of the cannon in an instant. The various colors of light were dazzling, like a straightened rainbow bridge, extending from this end of the war fortress and landing on the defensive force field of the mobile fortress group.

And with the arrival of the cannon light, the defensive force field of the mobile fortress group also became more dazzling in an instant. Originally, it was just a barrier of energy, but at this time, it seemed as if it had substance, and it looked like a crystal wall with a thick crystal. At the moment when the attack and defense came into contact, the crystal walls condensed by those defensive force fields were like tempered glass that had been hammered, and soon they were densely covered with cracks of various colors.

"It's not good, the defense must be broken, notify to increase the energy output, and charge the magic crystal cannon to prepare for a counterattack!"

"Crystal Cannon Charge!" the commander-in-chief's order was teleported to the other mobile fortresses, and then quickly reached the ears of the gunners.

So, the sixteen mobile fortresses opened their cannon doors like waves, pointing the muzzles of the magic crystal cannons at the war fortress. The muzzles of those magic crystal cannons, while also being revealed, lit up with clusters of light, even under the reflection of the "Rainbow Bridge", they still flickered like stars.

"Although they are put together, they are not a real whole after all, so let's see how far you can go!" Ye Zan's side naturally noticed the changes in the enemy, but he did not have a special reaction to this. It's not that he despises it, it's really this move of the enemy, and it is impossible to pose a threat to the fortress of war at all. After all, the outer defense of this war fortress was built by the bone fragments of the True Immortal-level Extraterrestrial Demon.

In fact, the sixteen mobile fortresses are gathered together, which is just a bit bluffing, but they are not really fused into one. For example, if you face a steel shield and a single wooden spear can't pierce it, can ten or a hundred wooden spears pierce it?

Quantity is just quantity, and although quantitative change may cause qualitative change, it also depends on the extent to which that quantity can reach. At least for now, just sixteen mobile fortresses combined, just the salvo of thousands of magic crystal cannons, is not enough to reach the level of qualitative change.

Thousands of magic crystal cannons finally fired, and one after another cannon light shot out from the cannon doors of the mobile fortress, densely packed like countless silk threads, shooting straight towards the war fortress. In just an instant, those cannon lights fell on the outer defensive force field of the war fortress, but it was as if countless rains were falling on the surface of the lake, and they only stirred up some small ripples.

"The other side's defenses are too strong, even beyond the defenses of the war fortress in our memory. "On the side of the demons outside the sky, seeing that this wave of shelling had no effect, although it was already expected, it still couldn't help but feel a little incredible. After all, even if this wave of shelling is impossible to bombard the fortress of war, it is necessary to make the other side "tremble" a few times.

In the face of such an opponent, the Outer Heaven Demon fell into a short silence, and for a moment he couldn't even think of how to take the next step.
