Next, Todd conducted repeated experiments on forty-nine white mice, repeatedly testing the dosage and timing of the addition of Sutherland archaea, mutant bacteria, and tyrant virus, ultimately arriving at a frustrating conclusion.

It is virtually impossible to achieve the evolution of an inheritor using quantitative control methods.

Of the forty-nine white mice used in the experiment, thirty-one died, thirteen underwent mutation but became "walking corpses," and only five white mice survived while retaining their consciousness.

However, these five white mice were all incompletely mutated. That is, parts of their bodies had mutated, but other parts remained normal mice, just like Jerome, the seventh in line of the 'Dissidia Legion,' who became a half-tyrant successor.

After conducting experiments for eleven consecutive hours, Todd, with aching and sore eyes, stared at the rat carcasses scattered all over the experimental chamber, his head throbbing with pain.

Todd placed a dead white rat on the dissection table, opened its skull with a scalpel, and closed his eyes in despair as he watched the brain tissue being slowly devoured by the black reticular formation.

The results of the experiment are now quite clear.

The consciousness collapse caused by the mutation of the inheritor and the brain tissue damage caused by the tyrant virus are like a pair of venomous snakes biting each other's tails. There is no perfect way to break this deadlock.

If the Tyrant Virus could truly be applied to the Successors, the secrets behind the Beacon Tower would need to be unlocked. But the latter, at present, is undoubtedly a pipe dream.

Having exhausted all other options, Todd tossed the scalpel onto the table, got up from his chair, and reluctantly headed towards the living room next to the laboratory, intending to rest for a while. As he passed the temperature-controlled warehouse, he inadvertently caught sight of the wooden barrels storing the 'Dragon Bone' parasites.

Suddenly, a flash of inspiration struck Todd.

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