Half a month later.

Strange vulture-like creatures the size of pterosaurs with smooth heads kept screaming, spreading their wings and flying in the sky on the edge of a cliff.

If you look at the ground from the sky with the cliff as the center, you will find countless large and small holes hidden and densely spread throughout the grassland.

From time to time, strange creatures will emerge from these holes, and the closer you get to the center of the cliff, the larger and more terrifying the creatures appear.

At this time, in the entire grassland, except for these strange creatures, there are basically no animals that are familiar to humans.

At the bottom of the cliff, there is a huge bottomless cavern.

At this time, in the deepest part of the cave, with a roar of slight pain, Xu Jing took the initiative to break free of the ovipositor, and then walked towards the ground under the escort of a group of aliens who were slightly larger than him.

At the same time, in the large and small holes in the grassland, countless aliens of all kinds ran to the ground and gathered in pieces.

In the past half a month, Xu Jing first hid in the old nest by the water source, laying a large number of alien eggs, and after hatching, countless face-hugging insects entered the water.

These face-hugging insects hide under the water, and when the animals come to drink water, they will suddenly pounce on the water and carry out face-hugging pregnancy.

Although some animals were killed on the spot by agile animals, as the number of face-hugging insects increased, the number of successes increased.

Antelope alien, zebra alien, lion alien, cheetah alien......

As Xu Jing's control became stronger, he shifted his focus to large animals such as rhinoceros, hippos, elephants, and giraffes.

In order to parasitize such animals, he came up with a parasitic method of instilling pregnancy from the buttocks or genitals after many experiments through capture and many experiments.

Compared to these large animals, the small face-hugging insects will burrow into their excretory or reproductive* organs, directly into their bodies, and then begin to conceive.

After conquering all the land creatures, Xu Jing turned his attention to the sky, small birds are not suitable for parasitism, so he set his sights on vultures, and finally obtained the desired flying class.

In addition, after a lot of experiments, he found that alien parasitism is actually doing species subtraction, or even species division.

That is to say, if you parasitize a wildebeest and parasitize a zebra, although the appearance of the alien is somewhat different, in the system display, the strength of the two is exactly the same.

There are many kinds of creatures on the grassland, and after trying all the animals that can parasitize, Xu Jing got six kinds of aliens in total.

The first is the aliens around him at the moment, these aliens are mainly hosts to creatures such as rhinoceros, hippos, bison, etc., they are huge, have bloated heads, have hard defenses like armor metal plates, and are strong in hand-to-hand combat, but the disadvantage is that they are not agile enough, slow speed, and cannot climb.

In the system display, the strength and special exoskeleton of this kind of alien have generally reached the level of seventh, and they also have a strong self-healing ability, the only deficiency is agility, only a mere level two.

Moreover, the system suggests that due to genetic limitations, this alien will inevitably lead to a weakening of abilities such as strength due to enhanced agility.

So Xu Jing didn't continue to strengthen, he simply left these aliens by his side and acted as his own guard.

The second type of xenomorph is generally hosted by antelopes, zebras and other herbivores that resemble the size, and this type of xenomorph is two levels stronger than the xenomorphs with humans as the host, and the abilities are very balanced.

What's more, these aliens are numerous, and they are the backbone of Xu Jing's alien army, and they are indispensable, and he calls these aliens warriors.

The third type of alien is based on creatures such as lions and cheetahs, and compared to the second alien, their abilities are equally balanced, but more prominent.

However, the number of such aliens is much less than that of warrior aliens, and Xu Jing assigned them to the warrior aliens as the captain of the leading warriors.

The fourth type of xenomorph is a host of large, heavyweight creatures such as elephants and giraffes, and their characteristics are similar to those of the Praetorian Xenomorph, but they are less agile and only level 1.

However, on the other hand, their strength, exoskeleton defense, and self-healing ability are also more powerful, basically reaching the level of ninth, and their body size is extremely large, with a height of about ten meters.

Xu Jing called these aliens tanks, in his estimation, there are not many, as long as one of these aliens can rampage through the human city, and the ordinary human beings cannot cause any harm at all.

The most powerful thing about the alien is the super corrosive blood in the body, it is good if it does not break the defense, if the defense is broken, the blood splash caused by such a behemoth is enough to melt the land of death into a sinkhole.

The fifth type of alien is the vulture alien flying in the sky at the moment, they are agile and prominent, their strength is not weak, and more importantly, they can fly.

There is also a sixth type of alien, which is born with jackals and hyenas as hosts, this alien is slightly smaller, agile and prominent, and has a strong sense of perception, is good at surrounding prey, and cooperates tacitly with each other.

Known as scouts, these xenomorphs are better at using their small size to conceal themselves than other xenomorphs, and can also give their enemies a lethal sneak attack if necessary.

During this time, Xu Jing has accumulated enough strength, and this area of grassland is not all his strength.

As early as a week ago, he went to several grasslands, each of which established nests, laid countless alien eggs, and a large number of aliens, which he assigned to disperse all over the world through the sea.

Of course, he also released a large number of face-hugging insects into the sea and parasitized the sea creatures, but after absorbing the genetic characteristics of those sea creatures, the main characteristics of the aliens that broke out of the cavity were that they tended to survive in the water, and many of them even degraded their legs.

As a result, Xu Jing could only give up the idea of moving to the sea.

In addition, there will always be some unexpected visitors from the human world on the grassland, and he has no mercy for these humans, and they are all captured and parasitic into aliens.

But after a long time, there are more people missing, and he is about to lose his sights.

Xu Jing had been in this world long enough, and now that the time was ripe, he didn't want to wait any longer, and if he wanted to complete the third task, he needed to make a big move to attract the attention of the Iron Blood Clan.

And the reason why he is so sure that he can attract the Predator is also because the system gave a hint a few days ago.

"Assemble!"

Out of the cave, Xu Jing gave an order, and a large number of aliens rushed to the ground from the underground hiding place, gathered together, and formed a mighty one.

This day is destined to be a historic moment.

All the human beings in this world, will be shocked by what happened on this day, remember this day, because from this day on, they will truly know that they are not overlords in this universe.
