Leon had seen firsthand the strange shapes and aberrations created by the creatures in the mission world.

The aberrations, though ugly and ugly, are impressive enough to handle some tough tasks - and that's if the biological master doesn't have an individual consciousness and is spontaneously created.

If the creatures that already exist on the earth can be transformed into biological weapons through guidance, mutagenesis, mutation, etc., then Li Ang can completely form an army by himself.

Wearing a chemical protective suit, Leon stood in the [Automated Pet Breeding Tank] woodland built by him, and muttered to himself, "The most critical problem is that the animal should be selected as the prototype of biological modification..."

He thought for a moment, and quickly circled several groups of animals.

First, the earthworms of the oligochaeta of the phylum Annelids,

Second, planarians of the planarian class Planarians

Thirdly, the neozoa of the phylum Neomorpha

Fourth, there are all kinds of insects of the class Arthropoda.

As a kind of lower annelid, the earthworm's body is roughly cylindrical, symmetrical on both sides, like two fusiform pipes set together, its outer layer is a body wall connected by a ring, the inside is a digestive tract, and the two fusiform pipes are filled with body cavity fluid.

When the earthworm is cut in two, the muscle tissue of its section will contract inward, and part of the muscle will self-dissolve to form a cell mass, and at the same time, it will cooperate with the white blood cells to form an embolism, so that the wound will be closed quickly.

At the same time, the protocytes located in the body cavity will cooperate with the lysed muscle cells to form regenerative buds in the cross-section, and the cells of the digestive tract and nervous system in the body will grow in the direction of the regenerated buds through mitosis, and finally the earthworm will return to its original state.

There are about 2,500 species of earthworms in the world, and not all earthworms have the ability to regenerate, and there are huge differences in the ability to regenerate between different species - Li Ang chose earthworms because there are enough earthworms sold on a treasure to find them one by one.

Unlike the corded nervous system of earthworms, planarians have a ladder-shaped nervous system - this more primitive central nervous system allows planarians to have the characteristics of "retaining their original memory after division", which can be used for rapid iteration of biological weapons.

The Nematode is the most powerful animal in the world to divide and regenerate, and the Nematode Lineussanguineus, which lives on the two coasts of the northeastern Atlantic Ocean and North America, can be cut repeatedly, even if it is chopped into 1/200,000 pieces, it can be reborn into a new individual, which is not much different from the blood rebirth in the fantasy.

These three types of invertebrate worms have their own advantages and disadvantages, and Leon decided to transform them in groups and guide them to see which player can be the first to qualify and become a qualified biological weapon.

Come on, irons, this is the last elimination system, and if you can't evolve, you will be thrown into the forging furnace by Leon as garbage.

As for the fourth category of insects, the range of options is quite large, ants, bees, beetles, flies, fleas, butterflies... Each insect has very distinct advantages.

It's a pity that the internal time flow rate of the [Automated Pet Breeding Tank] is consistent with the outside world, and the killing game will not give Leon more time to develop, so he designated the key target of biological transformation as the Hymenoptera bees.

There are a total of 37 orders under the insect class, including Coleoptera, Diptera, Lepidoptera, Hemiptera, and Orthoptera, among which the bees of Hymenoptera are far inferior to other insects in terms of body strength and development potential.

But bees have three advantages.

First of all, it belongs to the complete metamorphosis development, through the egg, larva, pupae and adult and other 4 stages, in the process of pupation, the vast majority of somatic cells in the larva will be programmed to die, disintegrate the cell-forming soup, and then the original adult disc will be rapidly produced, in the cell soup to differentiate the various parts of the adult.

In other words, the larvae and adults of a completely metamorphosed insect are two different individuals... It's a little scary when you think about it.

In short, in the process of pupating, Leon can use the [Biological Master] to intervene, causing it to differentiate the parts he wants in advance and directly produce new insects - this can save a lot of sanity value.

Another advantage of the bee is that it is itself a highly specialized species with a socialized division of labor.

The queen bee has a big belly and relies on worker bees to feed, and can produce 800 eggs a day, and if she is fully producing, she can give birth to more, which perfectly meets the needs of Leon who needs a large number of experimental individuals.

The former is responsible for sacrificing their lives for the reproduction of the population, while the latter is responsible for collecting honey, keeping warm and incubating eggs, raising larvae, waxing and creating a spleen, and defending the nest door.

Finally, bees can communicate through pheromones, and as long as Leon differentiates himself with a glandular organ that specializes in the production of pheromones, he can communicate directly with the bee and facilitate his control.

After selecting these four main players, Li Ang began to use the [Biological Master] to transform and differentiate.

He first picked dozens of earthworms with good nutritional status, cut them in two, and took advantage of the time when they writhed to recover, and used the master to "blow" their regenerated buds, so that the two earthworms newly grown half of the halfway were larger than the original half.

After the two top-heavy earthworms got used to it for a while, Leon swung his knife and cut off the original half, and concocted it again, making the earthworms bigger and bigger.

Subsequently, he made various modifications on the hundreds of giant earthworms, either to grow four soft feet connected to the corded nervous system, or to specialize in a strong carapace on the head, or to enhance its photoreceptor organs, or all of these advantages.

In total, Leon divided dozens of groups of various earthworms and threw them into all corners of the woodland.

One of the major features of [Automated Pet Breeding Box] is that it will use the most advanced life form inside it as a limited feeding object.

After these earthworms have undergone transformation, their ecological level has risen in a straight line, and they have become the priority objects of terrarium care - the boxes will subtly ensure the survival of earthworms to the greatest extent by means of soft ground and breeze to accumulate humus in front of earthworms.

Leon also did the same with planarians and newworms, creating dozens of different groups of specialized species that were scattered all over the woodland.

The last bee, Li Ang, bought a few boxes directly from a certain treasure like an earthworm, and piled them all up in the corner of the woodland - it doesn't matter if there is no nectar source, you can feed it with white sugar and pollen anyway.

Making biological weapons is a long-term investment, and even if it fails, it will not lose money.

Leon takes care of everything in the [Automated Pet Breeding Tank], waits until the queen bee starts laying eggs, makes minor adjustments to the eggs, and then teleports out of the box and back to the real world.

Calculating the time, it's almost time for the next script mission.
