It might be because it had previously devoured the flesh and genes of many magical beasts, along with many different kinds of elixirs.
Finally, through the stimulation of dragon's blood grass.
The Zerg army is now gradually developing an internal skeleton!
The internal skeleton is also a crucial factor that limits the size of an organism.
Small insects only have an exoskeleton because they are small and do not need an internal skeleton to support their muscle tissue and various organs.
Therefore, by growing some exoskeleton, one can fully protect oneself and support one's body.
However, once the body size increases, the weight will also increase. Faced with the influence of gravity, without the support of the internal skeleton, it is easy to collapse into a pile of flesh.
Therefore, despite Zhao Zi'an's continuous efforts, the size of the Zerg army could only grow slowly and could never become too large.
Zhao Zian reluctantly shifted his gaze away from Xiao Yi.
Consciousness returns to the original body, opening the gene modification option from the perspective of a god.
These internal skeletal genes were all automatically integrated into the gene templates of various Zerg units.
Zhao Zian didn't need to do any modifications himself.
Because some genes with a particularly high degree of fusion can fuse directly on their own.
It seems this endoskeletal gene is a perfect match for his Zerg army, Zhao Zian thought to himself.
The formation of the endoskeleton meant that giant creatures finally had a basis for formation.
It's no longer the time when insects that are only a few tens of centimeters long can be called giant units.
In the past, the genes of insects, no matter how much they were enhanced, had a limit.
If you really want to evolve into a super-giant creature that is tens or even hundreds of meters long, you still need an endoskeleton.
The development of exoskeletons is unlikely to make much of a difference in body size; it can only be developed to increase defensive and combat capabilities.
It's not just that the endoskeleton genes have fused automatically.
Previously, it had devoured the corpses of various core areas of magical beasts, and the genes of these magical beasts were highly integrated.
They automatically merged with each other, forming two completely new units.
Zhao Zian originally planned to use genetic modification to obtain new types of soldiers.
This time, without any cost, they directly obtained two new units for free, and they couldn't stop smiling.
The first new unit in this comprehensive evolution is a giant unit that is over three meters long, nearly four meters long, and two meters tall.
Although this unit is only a little over two meters tall now, it has already laid a dual foundation of endoskeleton and exoskeleton.
The foundation is already solid, the potential is huge, and the ceiling will be very high.
Using giant soldier ants as the initial genetic template, it incorporated the genes of bovine magical beasts that it had devoured on the battlefield, along with a trace of dragon blood.
Two enormous chitinous exoskeletons protrude outwards from the front of the head, forming two incredibly ferocious super ramming horns.
Its sharp horns, combined with its massive body, constantly exuded a chilling aura of slaughter.
Below the ram are two scythe-shaped jaws. While charging and ramming the enemy, you can also use the jaws to harvest the enemy like scythes cutting wheat.
Its skin was pitch black, and its entire body was covered in exoskeleton armor, with only its eyes showing.
The legs are no longer as slender as they used to be on worms.
With the support of the endoskeleton, the six legs became stronger and were no longer as easily broken as before.
Furthermore, there are barbs attached to the joints, and there are no toes in the traditional sense, only claw-like spikes formed by protruding exoskeletons.
If you get stepped on, you're doomed.
Zhao Zian named this unit "War Beast".
This thing is indeed powerful, but the consumption is too great, and the Zerg army certainly can't produce too many of them.
It serves as the vanguard, leading the charge and disrupting the enemy's formation.
Producing just a few at the front of the line is enough.
The second type of unit is a smaller unit.
This uses giant worker ants as the initial genetic template.
It incorporates the genes of the mantis monster found on the battlefield.
Actually, this monster is quite different from a real-life praying mantis...
It's mainly because they look similar, so that's how Zhao Zi'an got his name. The two large cleavers in front are quite descriptive.
It also incorporates some Warcraft genes from grasshoppers that jump very high.
It is about 30 centimeters long and its body is similar to that of a worker ant.
However, its chest and head were no longer lying on the ground, but were slightly raised like a praying mantis.
The six limbs, also supported by an internal skeleton, became thicker and were all concentrated in the lower body.
Two new growths appeared on the front of the raised chest, resembling two sharp cleavers.
However, the edges of these two large cleavers are not as sharp as those of a normal kitchen knife.
Instead, it's like a saw, full of barbs, capable of instantly controlling enemies and then harvesting them with its mouth, or damaging enemies by constantly cutting back and forth.
The two scythes at the front of the mantis are not actually for the purpose of winning, since those two scythes are just things that grow on the mantis itself and cannot be compared with real iron weapons.
It can't be chopped down like a kitchen knife, cutting in two with a single stroke.
Its main function is to hook its prey with its dense barbs, making it unable to escape.
The praying mantis's strongest attack capability is actually its mouth; after controlling its prey, it often needs to use its mouth to finish it off.
When I was a kid, I was just captivated by the two mantis spirits in the show "Seer" and their constantly flashing blades and sharp cleavers.
When I was little, I really thought that mantises had very sharp sickles...
Actually, the mantis's two large cleavers aren't sharp at all...
This new unit still has a very sharp beak, and coupled with the grasshopper's genes, it jumps very high.
They move quickly by constantly jumping, and their mobility is much faster than that of ordinary Zerg.
However, to enhance its mobility, the exoskeleton armor of this new Zerg unit is not as thick as that of the worker ants.
On the contrary, they are similar to flying insects and belong to the category of light armor units.
However, although its defense is low, its agility is greatly increased, making it difficult for enemies to attack it.
And although it grew two new pairs of large cleavers, its exoskeleton armor became thinner, so its energy consumption was actually not much different from that of the giant worker ant.
Incidentally, the giant worker ants are now 30 centimeters long.
Zhao Zian simply named this new unit "Flying Bug".
With its powerful attack capabilities and exceptionally agile mobility, but also its fragile body, it's a real shame it's not called a Zergling.
After learning about the two new units, Zhao Zian looked at the old combat units.
Other old units haven't changed much in appearance, basically just with the addition of endoskeletal genes and a trace of dragon bloodline from dragon blood grass.
Their physical appearance has improved to some extent.
