Taking the "keel" parasites out of the container, Todd prepared supernatural bacteria, Sutherland archaea, and tyrant virus, and began a series of experimental procedures.

The first experiment was to inject supernatural bacteria into the body of the keel parasite.

A certain amount of regenerative bacteria was injected into the keel with a syringe. Ten minutes passed. After a violent struggle, the keel parasite slowly fell into death and lost its vital signs.

Todd dissected the parasite and took a slice and sample, and the result was similar to what he expected.

As soon as the dysfunctional bacterium comes into contact with the cell tissue in the parasite, the latter produces a severe allergic reaction (), the host cells die in large numbers, and the parasite and the bacteria eventually die together.

In the second experiment, Todd injected both Sutherland archaea and super bacteria into the parasite at the same time. The dosage ratio of the two did not cause archaeal mutation.

After injecting the two kinds of bacteria into the parasite, Todd waited for more than an hour, and the parasite was all normal, as if nothing happened.

Then the parasites were dissected, and samples were taken for observation.

Todd discovered that Sutherland archaea encapsulated the supernatural bacteria and filtered out allergenic toxins. However, the nerve tissue of the parasite is different from the nerve center of humans and animals. The former is just a simple nerve fiber and cannot provide a suitable lodging environment. As a result, Sutherland archaea and dysfunctional bacteria do not form effective infections. The secretions of the parasites are drained out of the body together.

The third experiment was still to inject Sutherland archaea and superb bacteria into the parasite, but this time, the dose of the two exceeded the red line of mutation.

Todd did not use a variety of bacteria to induce mutations, but increased the injection dose of regenerated bacteria to cause Sutherland archaea to mutate.

The mutated archaea began to attack every cell in the parasite. With the characteristics of regenerated bacteria, each limb of the keel parasite began to grow wildly. The limbs of the parasite that could only support human limbs were actually short. Within two minutes, it grew to several meters in length.

With the lessons of the first test accident, Todd reacted quickly. When the parasites began to mutate, he entered a monster state and pressed the frantic parasites on the table.

After more than ten minutes of wrestling, the keel parasite that grew crazily finally stopped growing, but at this time its body shape had become seven times its original size.

Todd used an iron chain to tie the mutated parasite firmly to the table, regaining his human form, sitting on the ground and gasping for breath.

"It seems that mutation is effective for parasites." Todd turned his attention to the "Amber Stone" on the material rack: "So, what effect will the Tyrant Virus bring?"

Five minutes later, the tyrant virus in the syringe needle was slowly injected into the mutated parasite. Todd looked at the mutated "keel" on the operating table, stopped struggling violently, his body gradually shrank, and finally became ordinary. Size, he sighed deeply.

According to common sense, the "dragon bone" parasite in front of us has completed its tyrant transformation and should have acquired the ability to evolve and transform.

But if you don’t try it yourself, you still can’t be sure whether the experiment is successful.

So Todd stripped off his clothes and began to put the "keel" on his body.

When the sharp spine spurs into Todd's body, the intense pain almost made him faint on the spot.

With the help of "Pain Resistance Ability", Todd slowly adapted to the existence of "Dragon Bone" and began to move his hands and feet.

After carefully checking the tyrannical "Dragon Bone Armor" on his body, Todd was a little disappointed, as if he was no different from before.

"It stands to reason that this set of dragon bones should have the ability to "enhance regeneration"."

Todd said as he raised his arm, recalling the scene of the parasite mutation of Shizue.

A scene happened without warning.

The upper limb joints of "Keel" suddenly grew rapidly, and the keel on Todd's wrist diverged into a brand new limb joint.

Todd looked a little dumbfounded at this newly grown keel limb, he thought about it carefully, and wondered: Could it be because the idea in his brain just passed along the spinal barb to the keel parasite? That's why it caused the mutation?

Thinking of this, Todd decided to try again. He imagined the appearance of a long sword in his mind. Sure enough, the keel on the left and right wrists grew forward about forty centimeters, looking like two swords connected to the body. . (The specific shape is similar to the Hidden Blade in Assassin's Creed)

Seeing this scene, Todd was overjoyed and quickly imagined the shape of a scimitar and shield in his mind.

The keel parasite on Todd's right palm grew rapidly toward the front of his palm, and finally formed a curved limb. The lower part of the limb was sharpened into a blade, and the upper part was dulled into a blade.

The keel parasite on the left arm is like the tentacles of an octopus, branching out countless flexible and intertwined limbs. These limbs finally form a thick and hard "shield".

Looking at the "Parasite Knife Shield" in front of him, Todd was taken aback, and gradually straightened out the working principle of the tyrant's parasite.

In the parasite, excessive regenerative bacteria triggered the mutation of Sutherland Archaea, and the Tyrant Virus stopped the mutation and evolved the regenerative ability into an "enhanced regeneration ability". However, because parasites have only nerve fibers and cannot freely control the transformation of form like organisms, if there is no external stimulus, the parasites will maintain their normal form and will not enter the evolutionary form.

And this so-called "external stimulus" is the nerve command of the host of the parasite-human beings.

When the host puts on the keel parasite, the instructions in the brain will be transmitted to the parasite through the spinal barb of the keel, and the latter will switch the part of the evolutionary form according to the neuron signal of the host.

At this point in the experiment, Todd discovered a new and creative way to use the tyrant virus, which is to turn the parasite into "tyrant equipment".

This discovery can completely increase the strength of the kingdom's successor army in a geometric form.

For example, the Dragonbone Parasite can not only be matched with the "Enhanced Regeneration Ability", it can also be matched with the "Enhanced Metal Skin Ability" to form a "Heavy Metal Dragon Bone". The metalized parasite limbs can effectively enhance the parasite protection ability, and also make the combination of "tyrant equipment" more diversified.

For another example, the Dragonbone Parasite can also be matched with the "Enhanced Flame Breath Ability" to become the "Flame Breath Dragon Bone". The tyrant successor who uses this combination will switch from a melee attack to a long-range fire attack. The scorching flame can shoot out through the parasite secretion glands in the palm of the hand, and the range can reach more than ten meters.

In addition to these, dragonbone parasites and "enhanced debilitating ability" can be combined to become "venomous dragon bone"; combined with "enhanced rapid ability" as "flashing dragon bone"; combined with "enhanced acid ability" as " Strong Acid Dragon Bone"; combined with "Enhanced Freezing Ability" to form "Frost Dragon Bone"...

With so many choices, Todd began to think about whether it is possible to inject all the abilities of bacteria into a set of "Dragon Bone Parasites" to create a "Tyrant Dragon Bone" that can use all the enhanced abilities. However, this attempt failed in the end.

The root cause of the failure is that the total amount of capable bacteria in the parasite is fixed, and the capable bacteria that exceed the upper limit of the capacity will be excreted by the parasite. Moreover, the type of supernatural bacteria in the parasite is inversely proportional to the power of the "Tyrant Dragon Bone", that is, the more types of superb bacteria, the lower the strength of the power released by the "Tyrant Dragon Bone"; the type of superb bacteria The less, the stronger the power released by "Tyrant Dragon Bone".

Is it complicated to understand?

It will be more intuitive to illustrate with practical examples.

If only "Enhanced Regeneration Bacteria" is added to the Dragonbone Parasite, the deformation and growth rate of the parasite limbs will be the fastest; but if you add "Enhanced Inflammatory Breath Bacteria" and "Enhanced Weakness" to it Power bacteria", although the dragonbone parasite can use the three abilities of strengthening regeneration, strengthening inflammation breath, and strengthening weakness at the same time, the deformation and growth rate of the parasite’s limbs will be greatly reduced. The use of the other two abilities will also Will be far inferior to the effect of only injecting a single species of bacteria.

Therefore, after repeated tests by Todd, "Tyrant's Dragon Bone" has two types of bacteria with the best abilities, and no more than three types at most.

After completing the above experiments, Todd began to write down the conclusions of the experiments in his notebook.

1. The keel parasite can be mutated by archaea, and the mutated form is directly related to the type of super-powerful bacteria. (For example, regenerative bacteria can cause rapid growth and deformation of the keel)

2. The mutated keel parasite ~lightnovelpub.net~ can be restored to its normal form with tyrant virus.

3. The tyrannical keel parasite can switch to an evolved form and use enhanced bacterial abilities.

Fourth, the host of the keel can send neuronal instructions to the parasite through the neural link between the two, and then freely switch the form of the parasite, and use the strengthening abilities in the parasite.

5. In order to maximize the effect of the tyrant's dragon bone, the types of bacteria injected into the parasite should be controlled to two to three. (Todd: As the successor of the tyrant, I have more than a dozen power-up abilities. If the useless power-up abilities can be removed from it, will the types of abilities in the Jing Simplified language also increase the strength of the abilities like the dragon bones? ?)

6. At present, only the tyrantization of keel parasites has been tested, and other parasites have not yet been tried. (Todd: There are more experimentally feasible parasites, including hive parasites, Tesla parasites, and rampant parasites. After these parasites are tyrannized, will they have creative effects with different types of enhanced abilities? ) Still worrying about not being able to find the latest chapter of the novel?
