Since returning from the Great Wilderness World, Ye has become the master of the small world, and with the pseudo-law by his side, the Zerg is basically of little use. After all, no matter how the Zerg Dao soldiers develop, at most they will reach a combat power close to the level of the Law Phase. Moreover, every time he wants to use the Zerg Dao soldiers, he has to release them in advance to arrange a large array, which is always a little inconvenient.

In fact, this can't blame the Zerg for being too weak, the main thing is that Ye Zan has made many restrictions on the Zerg. In terms of the reproduction of the Zerg, Ye Zan almost only let the other party breed Dao soldiers and war soldiers, and the other species are only slightly supplemented. After all, what Ye Zan needed most at the beginning, that is, the fact that the Zerg could cultivate Dao soldiers, other kinds of insects were not of much use.

In addition, the Zerg do not have a good enough environment to survive and reproduce, and they can only be locked in a small jade ball space all the time. And being locked up in the jade ball space means that everything that the Zerg needs to reproduce and grow, from energy to nutrients, needs to be provided by Ye Zan alone. Although Ye Zan is "not bad for money", it is impossible for him to really let the Zerg consume it, so he naturally attaches great importance to "cost performance".

What is "value for money"?

That is, the changes of the Zerg in some aspects may play a key role in the development of the entire race. However, unable to provide more combat power and deal with the common problems of the monastic world, Ye Zan would restrict those aspects. It's like putting a mold on some fruit and making it grow just the way you want it to, or pruning a potted plant or something.

Of course, if the Zerg can evolve freely, they may not see any effect now, but they will show more powerful power in the future. However, Ye Zan didn't want anything in the future, he just wanted to use the Zerg to deal with the immediate problem. After all, although the "later" thing can be regarded as an investment or something, it is also possible to lose money when investing.

Many things, in terms of "input" and "output", have a gradual decay trend. For example, at the beginning, you can get a return of "ten" if you invest in "one", and it slowly becomes "one" to get "one", and later it may become "ten" to get "one".

Therefore, in the view of Ye Zan, who values "cost performance", there needs to be a limit to the investment in the Zerg, rather than unlimited investment. After all, his own strength is also increasing and powerful, and if he doesn't need the Zerg now, he may not need it in the future, even if the Zerg evolves.

Even now, Ye Zan used the Zerg again, in fact, he didn't value the combat power of the Zerg very much, but used the Zerg to make up for the shortcomings of his own side. If you really want to cultivate the Zerg to the point where you can compete with the Tongtian Supreme and even the True Immortal, Ye Zan might as well find a way to bring himself to that level.

While waiting for the Zerg to breed and develop, although Ye Zan did not save those giant natives, he was not completely idle. He took advantage of the waiting time to release more detectors into the savage world, and he expanded outward to explore the surrounding situation first.

Therefore, when the Zerg had a certain scale, Ye Zan already had a more and clearer understanding of the situation in the barbarian world. For example, on the territory of the three-ring tower they are now in, in addition to the two mobile fortresses that were knocked down before, Ye Zan also explored the location of several other mobile fortresses. Ye Zan also saw some of the things that the extraterrestrial demons of the Three-Ring Tower did during this period, such as the slaughter of the giant natives.

Fortunately, although the giant natives have not formed a civilization, they are not really like those beasts, stupidly waiting for the "hunters" to hunt and kill. Although they are powerless to resist, they will always run away, hide, and even lead some ferocious beasts to fight against the demons outside the sky. Therefore, although Ye Zan and the others stopped here for nearly a month, the giant natives in this area have not been completely wiped out.

Of course, there is also a reason here, that is, the evil demons outside the sky are not very careful in slaughtering. In other words, the demons outside the sky have used this slaughter as a game to kill loneliness and relieve fear. If the Outer Demons are really bent on exterminating the Giant Natives, and really regard this as a task that needs to be completed as soon as possible, I am afraid that no matter how much the Giant Natives struggle, it will be useless.

"Although the Outer Heaven Demon doesn't seem to be very attentive, in the past nearly a month, less than a tenth of the giant natives in this area have left. Fortunately, the Zerg has also become a scale here, and then I will let the Zerg expand outside this area, and we will go and deal with the extraterrestrial demons in this area first. Ye Zan told everyone what he was going to do next.

With the strength of Ye Zan's side, if he simply dealt with the demons outside the world of this "Three-Ring Tower", it would not be much difficult. The reason why there is a shortage of manpower is mainly because Ye Zan is worried that when he and the others deal with the "Three Ring Tower", they will attract the attention and participation of other demonic forces outside the sky.

Therefore, Ye Zan's task to the Zerg was not to help himself deal with the "Three-Ring Tower", but to find trouble for the forces of other demons outside the sky.

"Are you finally going to act? We can't wait!" Cassalo and the others said excitedly. It's not that they're belligerent, and even though there are belligerent reasons, it's the fact that they really get so excited because it represents the credit of "preaching."

"However, Brother Ye, can these zergs really buy us enough time?" Lin Mumu said with some concern.

"Don't worry, don't look at the individual strength of the Zerg, but let them develop into a scale, the number will definitely make people desperate. Moreover, they will adjust their abilities according to the situation, and their adaptability is far beyond that of our human race. Perhaps, they don't have the ability to deal with other extraterrestrial demons, and it will definitely give the other party a lot of headaches. Ye Zan said with confidence.

At this time, after less than a month of development, the Zerg not only has a huge number, but also a very complete species. It can be said that what flies in the sky, runs on the ground, runs in the water, jumps in the grass nest, and it really has everything. Some bugs are like tanks, some are the size of bullets, some are like bombers flying in the sky, and some are like submarines in the dirt.

Although it is only a zerg, relying on genetic adjustment, it has created a trinity of sea, land and air bug army. Although such an army is not enough to overthrow the demons outside the world, it should still be possible to just make trouble for the demons outside the world, so that the other party has no time to take care of other situations.

Moreover, there is another advantage of using the Zerg, that is, it will not expose the news of the arrival of Ye Zan and his party on the side of the evil demons outside the sky. After all, in this world where everything is "gigantic", there are all kinds of huge bugs, and the Zerg will not be so conspicuous. Therefore, in the face of the attack of the Zerg, the Outer Heaven Demon is likely to simply think that these insects are just the indigenous creatures of this world.

"Brother Ye, I don't know if these insects will pose any threat to those giant natives? In case, the giant natives who were not exterminated by the demons outside the sky were exterminated by these insects, then ......" Lin Miaomiao thought of another important question.

With my control over the Zerg Mother Emperor, these insects are actually very obedient and will not pose a threat to the natives. In addition, I have also made a set, after solving the evil demons outside the sky, except for some bugs that will be taken back by me, the other bugs will be automatically cut off, and they will not continue to stay in this world. In order to reassure everyone, Ye Zan said his disposal of the Zerg.

After some inquiries and answers, Ye Zan and his party finally had no worries, and rode the war fortress to the outer demons of the Third Ring Tower.

At this time, in this area, the extraterrestrial demons of the Three-Ring Tower were hunting those giant natives everywhere, so several mobile fortresses were scattered everywhere. Originally, it was impossible for the power of the three-ring tower to compete with Ye Zan and his party, not to mention that the power was dispersed like this, which gave Ye Zan a chance to break through.

Ye Zan clearly grasped the whereabouts of the demons outside the sky through the detectors that were released, so he quickly found one of the mobile fortresses.

This mobile fortress was constantly blasting out cannon lights to the ground at this time, forcing the giant natives on the ground to flee in all directions with a wail. It was obvious that the demons outside the sky were "having fun" again, and they could kill those giants and natives very happily, but they only shot the cannon light at their side and feet.

"It's really hateful and hateful, you can kill them happily, but you want to play it like this!" Seeing the scene there, Casaro and the others on the war fortress couldn't help but say with disgust on their faces.

"Lao Ka, what you said is not right, if they didn't do this, we might not have a chance to save these natives. Ye Zan's words cannot be regarded as relief, but they are also facts that cannot be denied.

"That's right!" Cassalo nodded and said to a few of his companions, "However, this is also an example for me and others, you can't make the same mistakes as them!"

"My sword is sharp!" Hartlane replied in a cold voice.

Immediately afterwards, after receiving Ye Zan's notice, Casaro and the others flew out of the war fortress, and the six of them surrounded the mobile fortress of the demons outside the sky. Maybe Casalo's words worked, or maybe everyone wasn't interested in making any games, so they all came up and threw out their ultimate.

The mobile fortress of the Outer Heaven Demon, although it was not comparable to ordinary law-level powerhouses in terms of attack and defense, but when it suddenly faced the siege of six law-level powerhouses, it could not escape the fate of being broken after all. Casaro and the other six law-level powerhouses, after surrounding the mobile fortress, only one person bombarded it with one big move, and the defense outside was bombarded.

Some blasted through the gates of the Mobile Fortress, some broke through the walls of the Mobile Fortress, and some broke through the cannon doors, in short, instantly turning the Mobile Fortress into a broken lantern. Then, Casaro and the other six law-level powerhouses rushed directly into the fortress from the holes they had blasted open, and a one-sided slaughter unfolded in an instant.

As mentioned before, the power left by the Outer Demons in the Savage World is not every mobile fortress that has a law-level powerhouse. After all, with the power of the mobile fortress, even if an ordinary Yuanshen-level person controls it inside, it can still exert a combat power that surpasses that of a law-level powerhouse. And this means that after the mobile fortress is breached, when the people inside face the law-level powerhouse, they can only rely on slaughter.

In just a few minutes, Casaro and the others flew out of the mobile fortress and flew back to the war fortress one by one refreshed.

"Ye, it's all settled!" Cassalo replied to Ye Zan .

"It's just little minions, if it weren't for the mobile fortress, I really left them with those giant natives, I don't know who played with whom. Hartlane said with some emotion.

"Probably, that's why they take pleasure in it. Ye Zan responded to everyone as he incorporated the mobile fortress into the small world.

The behavior of those demons outside the world is probably also a bit of "being proud and rampant", after all, not everyone has the opportunity to abuse an existence that is stronger than themselves.

It's like some people like to watch geniuses fall, like to watch rich people go bankrupt, like to watch goddesses meet scumbags, and so on. They stood on the mountainside, not having the courage to step to the top of the mountain, and comforted themselves with the person who fell from the top of the mountain, but fortunately they were "smart" to stop here.

"Go on, try to clean up the power of the Three-Ring Tower as soon as possible!" Ye Zan didn't pay attention to the giant natives below, but led everyone to continue to move towards the next goal.

When Ye Zan cleaned up the power of the Three-Ring Tower, the power of the Zerg had also spread beyond the territory of the Three-Ring Tower, and launched an attack on the extraterrestrial demons in those places. With the reconnaissance information provided by Ye Zan's side, the Zerg didn't need to look for the enemy at all, and several Zerg armies directly pointed to their respective targets.

A mobile fortress on a mission to hunt giant natives treats the slaughter as a game. However, just as they were about to end the game, they saw a black cloud rise from the forest not far away, sweeping towards them with a "buzzing" sound.

The Outer Demons in the mobile fortress were a little surprised by this scene, but they quickly took countermeasures. The Moving Fortress unfolds its defensive armor, activating the energy protection field while turning the muzzle of the Crystal Cannon from the ground to the black cloud.

"What is that, it's a group of flying insects, such a big flying insect!" said the extraterrestrial demon in charge of the observation, after seeing the true face of the black cloud, he was a little inexplicable.

"Is it just a bunch of bugs? then there's nothing to worry about, fire!" Knowing that it was just bugs that were being faced, most of the Outer Demons regarded this as a continuation of the game, and they all showed very indifferent expressions.

The magic crystal cannon on the moving fortress instantly spewed out a series of cannon lights, straight into the oncoming black clouds. In the face of the cannon light, the flying insects in the black cloud did not look very abnormal, and they were almost powerless to be blasted into ashes by the cannon light.
