Taking the keel parasite out of the container, Todd prepared the 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. After ten minutes passed, the keel parasite slowly fell into dead silence after a violent struggle, losing signs of life.

Todd cut open the parasite and took a slice sample, and the result was about the same as he expected.

As soon as the supernatural bacteria come into contact with the cells and tissues in the parasite, the latter will produce a severe allergic reaction (hyperentitive reaction), the host cells will die in large numbers, and the parasite and the bacteria will eventually die together.

In the second experiment, Todd injected the Sutherland archaea and the supernatural bacteria into the parasite at the same time, and the dose ratio of the two did not cause the archaea to mutate.

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

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

Todd found that the Sutherland archaea encased the psychic bacteria and filtered out the allergenic toxins. However, because the parasite's nerve tissue is different from the nerve centers of humans and animals, the former is just simple nerve fibers, which cannot provide a suitable host environment, causing the Sutherland archaea and heterobacteria to not form an effective infection, and finally excreted out of the body along with the secretion of the parasite.

The third experiment was still to inject Sutherland archaea and supernatural 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 mutations in Sutherland archaea.

The mutated archaea began to attack every cell in the parasite. With the characteristics of the regenerating bacteria, each limb of the keel parasite began to grow wildly. The parasite's limbs, which could only support human limbs, grew to a length of several meters in just two minutes.

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

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

Todd tied the mutated parasite firmly to the table with an iron chain, and when he regained his human form, he sat on the ground and panted heavily.

It seems that mutation is effective for parasites. Todd turned his attention to the Amber Stone on the material shelf: So, what effect will the tyrant virus bring?

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 his body gradually shrunk until it finally became a normal size. He let out a deep breath.

According to common sense, the keel parasite in front of him has completed the tyranny, and should have acquired the ability to evolve and transform.

But if you don't try it yourself, you can't be sure whether the experiment was successful after all.

So, Todd simply took off all his clothes and began to put on the keel.

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

With the help of the pain resistance ability, Todd, who gradually adapted to the existence of the keel, began to move his hands and feet.

Taking a closer look at the tyrannical 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'.

As Todd said this, he raised his arms, recalling the scene where the parasite mutated just now.

A scene happened without warning.

The upper limbs of the Keel suddenly grew rapidly, and the keel at Todd's wrist branched out into a brand new limb.

Todd was a little dumbfounded looking at the newly grown keel limb. He thought about it carefully, and wondered in his heart: Could it be that the thoughts in his brain were sent to the keel parasite along the spine hook just now, which caused the mutation?

Thinking of this, Todd decided to try again. He imagined the appearance of the long sword in his mind, and sure enough, the keels at the left and right wrists grew about forty centimeters forward, which looked like two boxing 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 the machete and shield in his mind.

The keel parasite in the heart of Todd's right hand grows rapidly towards the front of the palm, and finally forms a limb with a curvature. The lower part of the limb is sharpened into a blade, and the upper part is blunted into a blade back.

The keel parasite on the left arm, like the tentacles of an octopus, branched out into countless flexible and intertwined limbs, and these limbs eventually coiled into a thick and hard shield.

Looking at the Parasite Knife Shield in front of him, Todd was taken aback, and gradually understood the working principle of the tyrant parasite.

In the parasite, excessive regeneration bacteria caused the mutation of the Sutherland archaea, while the tyrant virus stopped the mutation and evolved the regeneration ability into enhanced regeneration ability. However, since parasites only have nerve fibers, they cannot freely control the transformation of form like organisms, so if there is no external stimulus, the parasite will maintain the general form and will not enter the evolutionary form.

And this so-called external stimulus is the neural 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 spine hook of the keel, and the latter will switch the position of the evolutionary form according to the host's neuron signals.

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

This discovery can completely increase the strength of the army of the successor of the kingdom geometrically.

For example, dragon bone parasite can not only be paired with improved regeneration ability, it can also be paired with improved metal skin ability to make heavy metal dragon bone. Metallized parasite limbs can effectively enhance the protection ability of parasites, and can also make the combination of tyrant equipment more diverse.

For another example, Dragon Bone Parasite can also be combined with Enhanced Flame Breath Ability to become Flame Breath Dragon Bone. Using this combination, the successor of the tyrant will change from melee attack to long-range fire-breathing attack. The scorching flames can be shot 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, keel parasites can be combined with enhanced debilitating ability to form venomous keel; combined with enhanced speed ability to form flash keel; combined with enhanced acid ability to form strong acid keel; combined with enhanced freezing ability to form frost keel...

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

The fundamental reason for the failure is that the total amount of supernatural bacteria that can function in the parasite is fixed, and the supernatural bacteria that exceed the upper limit of capacity will be excreted by the parasite. Moreover, the type of supernatural bacteria in the parasite is inversely proportional to the strength of the power of the Tyrant Keel, that is, the more types of supernatural bacteria, the lower the strength of the power released by Tyrant Keel; the fewer types of supernatural bacteria, the higher the strength of the power released by Tyrant Keel.

Is it a bit complicated to understand?

It will be more intuitive to illustrate with practical examples.

If only enhanced regenerative bacteria is added to the keel parasite, then the deformation and growth speed of the parasite's limbs will reach the fastest; but if enhanced inflammatory bacteria and enhanced weakening bacteria are added to it, although the keel parasite can use the three abilities of enhanced regeneration, enhanced inflammation, and enhanced weakening at the same time, the deformation and growth speed of the parasite's limbs will be greatly reduced.

Therefore, after Todd's repeated tests, the best type of supernatural bacteria for Tyrant Keel is two, and no more than three.

After finishing the above-mentioned experiments, Todd began to write down the conclusions of the experiments word by word in his notebook.

1. Keel parasites can be mutated by archaea, and the mutated form is directly related to the type of supernatural bacteria. (such as regenerative bacteria, which can cause the rapid growth and deformation of the keel)

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

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

4. The host of the keel can send neuron instructions to the parasite through the neural connection between the two, and then freely switch the form of the parasite, and use the enhanced ability in the parasite.

5. In order to maximize the supernatural effect of the tyrant keel, the types of supernatural bacteria injected into the parasite should be limited to two or three. (Todd: As the successor of the tyrant, I have more than a dozen kinds of strengthening abilities. If I can remove the useless strengthening abilities and simplify the types of abilities in my body, will I also increase the strength of the abilities like the keel?)

6. At present, only the tyranny of the keel parasite has been tested, and other parasites have not been tried. (Todd: Comparing experimentally feasible parasites, including hive parasites, Tesla parasites, and berserk parasites, after these parasites are tyrannized, will they form creative effects with different types of enhanced abilities?)
