The first thing Todd had to do after closing the door to the laboratory was to confirm the state in his body.

He roughly calculated that there were currently more than ten abilities in his body, such as "Perspective", "Weakness", "Eagle Eye", "Speed", "Regeneration", "Strength Enhancement", "Underwater Breathing", "Metallic Skin", "Pain Suppression", "Soil Control", "Changing Appearance", and "Soul Link".

Due to the physical mutation caused by Sutherland archaea, the body's tolerance environment has been greatly strengthened, so that the upper limit of the capacity of the abnormal bacteria in Todd's body has been greatly increased, and the original limit of the number of abilities has been broken.

Mutations caused by archaea can evolve the body into a monster form that matches the ability, such as metal skin that turns a mutant's outer skin into a sturdy semi-metalized armor, and speed that allows limbs to evolve into monster forms that are more suitable for running and jumping. However, mutation can also cause all cells in the body to be attacked indiscriminately, eventually causing the organism to become a mindless monster.

The Tyrant Virus is mainly active in the nervous system, and its benefit lies in the fact that on the one hand, it can enhance the abnormal bacteria, and on the other hand, it can force the mutation in the body to be stopped. The harm is that if there are no mutated Sutherland archaea in the organism, then the tyrant virus will attack the entire nerve center.

The current task is to find a way to give them the evolved abilities of the tyrant on the basis of maintaining the consciousness of the heirs. Based on this premise, Todd wrote down the words "Sutherland archaea", "abnormal bacteria", "tyrant virus", and "monster form" in his notebook.

The first is the dosage of Sutherland archaea. At present, Sutherland's archaea have entered the mass production stage, and there are more than 50 volcanic environment simulators used to produce archaea in the Strange Factory, which can artificially breed about 60 inheritors every month, and there are now more than 800 inheritors in the entire Twilight City. So, the production of archaea is not a problem.

Todd made a cross on the Sutherland archaea.

Then there is the issue of "abnormal bacteria". In Twilight City, the kingdom will regularly organize xenomorphs to sample and extract abnormal bacteria, and build a special place to cultivate and store bacteria, so the stock of abnormal bacteria is not a problem.

Todd made another cross on the "Abnormal Bacteria".

Then there is the "Tyrant Virus", which is essentially a special bacteriophage that can multiply and expand by devouring bacteria, so there is no need to worry about the number of viruses at all.

The "Tyrant Virus" has been crossed.

Todd looked at the phrase "monster form" in his notebook and fell into deep thought.

If it is a successor who has not yet mutated and comes into contact with the Tyrant Virus, the nerve center will lose its function due to the devouring of the virus, but if it is a mutated successor and comes into contact with the Tyrant Virus, although the attack of the virus can be suppressed, all organs and tissues in the entire body will be destroyed and changed due to the mutation, and then become a mindless monster.

These problems, so that the use of the tyrant virus, into a dilemma.

If you don't mutate, you will die, and if you mutate, you will become unconscious monsters......

Todd threw away the pen in his hand, looked at the last word "monster form", and scratched his hair in annoyance.

Isn't there any way to protect the consciousness of the inheritor from being destroyed in the process of mutation?

Thinking of this, Todd's mouth opened slightly, and he froze in place.

He suddenly remembered that there was indeed an inheritor who had completed the mutation and retained consciousness after being exposed to the tyrant virus, and this person was Todd himself!

Todd rubbed his forehead vigorously with his hand and muttered to himself, "Think about it, think about it carefully, how did I come into contact with the Tyrant virus?!"

Memories of the past poured into Todd's mind like a tidal wave.

A life-and-death battle with Grass.

The underground temple of the Land of Shadows.

A huge whirlpool beneath the island.

A dark portal deep under the sea.

Finally, the Blackstone Beacon Tower of Jingjuku ......

Todd frowned, and secretly thought in his heart, could it be that the reason why he was able to preserve his consciousness in the process of mutation was because of the mysterious beacon tower?

If it were true, then applying the tyrant to the heir would turn into an almost impossible task.

Because if the kingdom wants to cultivate a tyrannical successor, it is necessary to let him go through a "trial of fate" that will kill him for a lifetime, which is simply a fantasy.

Todd thought for a moment, and then remembered that in the ruins of the North Island, there was an identical beacon tower, could it be used to complete the mutation of the heir?

Later, Todd rejected the proposal.

Jingsu once said that the beacon tower in the North Island has run out of energy and is no longer in operation. Moreover, allowing other people's consciousness to enter the space of the Beacon Tower means meeting Jingsu. Next, no one can predict what will happen, and the uncertain risk factor is simply too great.

Todd leaned back, looked at the ceiling, and let out a long sigh.

Trying to use the Beacon Tower to complete the mutation of the Successor seems to be an unachievable solution.

As a last resort, Todd resorted to other methods to achieve the tyranny of his successor.

The first thing that came to Todd's mind was the quantitative control commonly used in biochemical experiments. To put it simply, it is to control the mutation and evolution process of organisms by strictly controlling the number of archaea and viruses injected into the organism, and to achieve the purpose of successor evolution by using time difference and alternating reactions.

Next, Todd experimented with forty-nine mice and repeated experiments on the dosage and addition time of Sutherland's archaea, abnormal bacteria, and tyrant virus, and finally came to a depressing conclusion.

It is basically impossible to achieve the evolution of the inheritors by means of quantitative control.

Of the forty-nine mice used for experiments, thirty-one died, thirteen mutated but became "walking corpses", and only five mice survived with consciousness retained.

However, these five mice are all incompletely mutated, that is, some of their bodies have been mutated, but the rest of them are still in the state of normal rats, just like Jerome, the seventh in line to the "Clash Army", who has become the half-tyrant successor.

Todd, who had been experimenting for eleven hours in a row, had a splitting headache as he looked at the rat corpses in the experiment box with sore eyes open.

Placing a dead mouse on the dissecting table, Todd opened its skull with a scalpel, and closed his eyes in frustration as he looked at the brain tissue that had been slowly devoured by the black reticulum.

So far in the experiment, the results have been obvious.

The collapse of consciousness caused by the mutation of the Inheritor and the destruction of brain tissue caused by the Tyrant virus are like a pair of poisonous snakes biting each other's tails, and there is no perfect way to solve this dead end.

If you really want the Tyrant Virus to actually apply to the Inheritors, you can't solve the secrets behind the Beacon Tower. But the latter, in the current view, is undoubtedly a fool's dream.

Todd, who had nothing to do, dropped the scalpel on the table, got up from the chair, and reluctantly walked to the living room next to the laboratory, intending to rest for a while. As I passed by the thermostatic warehouse, I suddenly stumbled upon a wooden barrel where the keel parasite was stored.

Suddenly, a flash of inspiration flashed through Todd's mind.

The tyrant virus attacks brain tissue and neurons in living organisms, but what happens if it is injected into parasites that have no brains at all, only the most primitive nerve fibers?
