Removing the Dragonbone parasite from the container, Todd prepares the Anomalous Bacteria, Sutherland Archaeaea, and the Tyrant Virus and begins a series of experiments.

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

A syringe was injected into the keel with a certain amount of regenerated bacteria, and ten minutes passed, and after a violent struggle, the keel parasite slowly fell into dead silence and lost signs of life.

Todd dissected the parasite and sliced it out, and the results were pretty much what he expected.

As soon as the parasite comes into contact with the cells and tissues in the parasite, the latter produces a severe hyperentitive reaction, and the host cells die in large quantities, and the parasite eventually dies together with the bacteria.

In the second experiment, Todd injected both Sutherland archaea and paranormal bacteria into the parasite, and the ratio of the two doses did not cause archaeal mutations.

After injecting the two bacteria into the parasite, Todd waited for almost an hour or so, and everything was fine with the parasite, as if nothing had happened.

The parasites are then dissected and samples are taken for observation.

Todd discovers that Sutherland's archaea encapsulate the paranormal bacteria and filter out allergen toxins. However, because the nerve tissue of the parasite is different from the nerve center of humans and animals, the former is just a simple nerve fiber, which cannot provide a suitable hosting environment, resulting in the Sutherland archaea and paranormal bacteria not forming an effective infection, and finally being excreted from the body along with the secretion of the parasite.

The third experiment was to inject Sutherland archaea and parabacteria into the parasite, but this time, the doses of both exceeded the red line of mutation.

Todd did not use a variety of bacteria to cause mutations, but instead caused the mutation of Sutherland's archaea by increasing the injection dose of regenerated bacteria.

The mutated archaea began to attack every cell in the parasite's body, and with the characteristics of the regenerative bacteria, each limb of the keel parasite began to grow wildly, and the parasite limbs, which were originally only able to support human limbs, actually grew to a length of several meters in just two minutes.

With the lessons learned from the first trial accident, Todd reacted quickly, and when the parasite began to mutate, he entered a monster state and pressed the parasite into a frenzy on the table.

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

Todd chained the mutated parasite to the table, and he returned to his human form and sat on the ground gasping for air.

"It seems that mutation works for parasites. Todd turned his gaze to the Amber Stone on the material shelf, "So, what will happen to the Tyrant Virus?"

Five minutes later, the tyrant virus in the syringe was slowly injected into the mutated parasite, Todd looked at the mutated "keel" on the operating table, stopped struggling violently, and gradually shrunk in size, and finally became an ordinary size, he exhaled deeply.

According to common sense, the 'dragon bone' parasite in front of him has completed its tyrantization and should have gained the ability to evolve and transform.

But if you don't try it yourself, you can't be sure if the experiment will be successful.

So, Todd simply stripped off his clothes and began to put on the "dragon bone" on his body.

When the sharp spurs of the vertebrae pierced Todd's body, the sharp pain nearly made him faint on the spot.

With the help of the "Pain Resistance Ability", Todd, who slowly adjusts to the presence of the "Dragonbone", begins to move his hands and feet.

After taking a closer look at the tyrant-like 'Dragon Bone Armor' on his body, Todd was a little disappointed, as if it was no different from before.

"It stands to reason that this set of keels should have the ability of 'Enhanced Regeneration.' ”

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

Without warning, a scene happened.

The upper limb of the "dragon bone" suddenly grew rapidly, and the keel on Todd's wrist branched off into a new limb.

Todd was a little dumbfounded when he looked at the newly grown keel limbs, he thought about it carefully, and said suspiciously: Could it be that the thoughts in his brain just now were teleported along the spine to the keel parasite, so it caused the mutation?

Thinking of this, Todd decided to try again, and he imagined in his mind what it would look like to start the long sword, and sure enough, the keels on the left and right wrists grew forward about forty centimeters, looking like two fist swords attached to the body. (Shaped like the Hidden Blade in Assassin's Creed)

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

The keel parasite in the center of Todd's right hand grew rapidly towards the front of the palm, and finally formed a curved limb, the bottom of which sharpened into a blade, and the top became blunted into the back of the knife.

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

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

In the parasite, an excess of regenerating bacteria caused the Sutherland archaea to mutate, and the Tyrant Virus aborted the mutation and evolved the regeneration ability into "enhanced regeneration." However, since parasites only have nerve fibers and cannot freely control morphological transformations like organisms, parasites will remain in their normal form without external stimuli and will not enter an evolutionary form.

And this so-called "external stimulus" is the neural instruction of the parasite host, the human being.

When the host wears the dragon bone parasite, the instructions in the brain are transmitted to the parasite through the hook of the dragon bone's spine, which will switch the part of the evolutionary form according to the host's neuronal signals.

At this point in the experiment, Todd discovered a new and creative way to use the Tyrant Virus in the application of the Tyrant Virus, that is, to make the parasite into a "Tyrant Equipment".

This discovery is completely capable of increasing the strength of the army of the successor of the kingdom in a geometric upward form.

For example, the Dragonbone Parasite can be paired not only with "Enhanced Regeneration", but also with "Enhanced Metal Skin" to become "Heavy Metal Dragonbone." Metalized parasite limbs can effectively enhance the parasite's protective ability, and can also make the combination of "Tyrant Equipment" more diverse.

For example, the Dragonbone Parasite can also be paired with "Enhanced Firebreath Ability" to become "Firebreath Dragonbone", and the Tyrant Successor who uses this combination will switch from melee attacks to ranged fire-breathing attacks. 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 away.

In addition to these, the Dragonbone Parasite can be paired with "Enhanced Debilitation" to become "Toxic Dragonbone", "Flash Keel" with "Enhanced Speed", "Acid Keel" with "Acid Enhanced", and "Frost Dragonbone" with "Enhanced Freeze......

With so many options, Todd began to wonder if he could inject all of the ability bacteria into a set of Dragonbone Parasites to create a Tyrant Bone that could use all of the power-ups. However, this attempt ultimately failed.

The root cause of the failure is that the total number of abnormal bacteria that can function in the parasite is fixed, and the abnormal bacteria that exceed the upper limit of the capacity will be excreted by the parasite. In addition, the type of abnormal bacteria in the parasite is inversely proportional to the ability strength of the "Tyrant Dragon's Bone", that is, the more types of abnormal bacteria, the lower the power strength of the "Tyrant Dragonbone", and the fewer types of abnormal bacteria, the higher the power intensity released by the "Tyrant Dragonbone".

Isn't it a bit complicated to understand?

It would be more intuitive to illustrate with practical examples.

If only the "Enhanced Regenerative Bacteria" is added to the Dragon Bone Parasite, the deformation and growth rate of the parasite's limbs will be the fastest, but if you add "Enhanced Inflammatory Breath Bacteria" and "Enhanced Debilitating Bacteria" to it, although the Dragon Bone Parasite can use the three abilities of Enhanced Regeneration, Enhanced Inflammation and Enhanced Weakening at the same time, the deformation and growth rate of the parasite's limbs will be greatly reduced, and the use of the other two abilities will be far less effective than just injecting a single type of bacteria.

Therefore, after Todd's repeated tests, the best types of abnormal bacteria in the "Tyrant Dragon's Bone" are two, and no more than three.

After doing all these experiments, Todd began to write down the conclusions of the experiments in his notebook, word by word.

1. Keel parasites can be mutated by archaea, and the mutated morphology is directly related to the type of abnormal bacteria. (For example, regenerative bacteria can cause rapid growth and deformation of keels)

2. The mutated keel parasite can be restored to its normal form with the Tyrant virus.

3. The tyrantified dragon bone parasite can switch to its evolved form and use the enhanced bacterial ability.

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 enhancement ability in the parasite's body.

5. In order to maximize the effect of the Tyrant's Dragon's Bone, the types of bacteria injected into the parasite should be limited to two or three. (Todd: As the Tyrant's Successor, I have more than a dozen enhancement abilities on my body, if I could remove these useless enhancements and streamline the types of abilities in my body, would I also increase the strength of my abilities like the Dragonbone?)

6. At present, only the tyrantization of the keel parasite has been experimented, and other parasites have not yet been tried. (Todd: Compare the experimentally feasible parasites, including the Hive Parasite, the Tesla Parasite, and the Berserk Parasite, if these parasites are tyrantized and combined with different types of power-ups, will they have a creative effect?)
