Starting with rogue ninjas, building the insect kingdom.

The eighth cell contains the Corrosive Worm.

It is an excellent variety induced and differentiated from the carrion parasite. More accurately, it is a new variety born from its hybridization and fusion with the original carrion parasite and external induction.

They possess all the abilities of parasites, have an extremely high reproductive capacity, and eat anything. When they are extremely hungry, soil and minerals become their food.

Although they do not possess any attributes and do not release toxins, their genes are extremely unstable and easily differentiate, which is also their greatest advantage.

The ninth cell contains the Stink Bug, a superior variety selected by Yu Nu Zhicheng through numerous experiments.

These are insect species that undergo induced mutations by feeding on large amounts of toxic fungi and putrefactive bacteria.

After a long period of targeted induction and accelerated evolution through the work of Aburame no Cheng, this insect species that can reproduce stably was eventually formed.

The only downside is the price; only a little over a hundred of these insects can be bred at a time, and each one costs the equivalent of five thousand ordinary worms.

The tenth cell contains the floating insect.

Its full name should actually be called the "Arc-Shaped Skeleton Internal Vacuum Water-Air Insect." It has only one function: to regulate the air density within its body, and in conjunction with the Insect Pad technique, to aid in flight.

It is entirely white, relatively large, and hollow inside.

It is the most docile of all insects, and can live as long as there is water.

It is also the most genetically stable of all insects, which means that it has almost lost any possibility of induced differentiation.

Therefore, it is the least promising of all insects.

The remaining two slots are empty, and these ten types of insects are all the insects that Shisei Aburame currently possesses.

"The parasitic insect can be eliminated."

He wasn't sure if his cheat system could evolve further, but it had remained at twelve slots for years and was unlikely to change.

Parasites like these can be bred later, so keeping them is just taking up space. It's better to clear out the space sooner rather than later.

He manipulated his mind to transfer all one hundred parasitic worms in the compartment into a petri dish, where some were broken down into materials and others were converted into energy.

After making slight adjustments, the internal environment was altered, the time change was accelerated, and the evolution was observed.

As early as six months ago, Shisei Aburame realized that he had entered a bottleneck period: his bones had taken shape, his body had matured, and the growth of his chakra had also entered a slow and stagnant state.

As is well known, chakra is refined from spiritual energy and cellular energy in a one-to-one ratio.

The fact that his chakra is growing slowly now means that his physical body is nearing its limit.

For a normal ninja to significantly increase their chakra, there are usually only two ways: one is a spiritual transformation, and the other is a physical transformation.

In terms of physical attributes, the Lightning Armor of the Hidden Cloud Village, which uses Lightning Release to stimulate cells, can barely be considered half a type, as it still has flaws and is not yet perfect; the others are mostly body modifications, but at this time Orochimaru has not yet begun to explore the true meaning of life.

As for methods of cultivating spiritual power, they almost never exist in the ninja world.

The vast majority of ninjas hone their bodies and temper their will through constant battles, or strengthen their beliefs, thereby transforming their mental strength, causing their chakra reserves to surge, and making their chakra more concentrated and imbued with personal will.

This is also the ninja way that some strong ninjas often talk about.

Aburame Shisei clearly did not possess such qualities, nor did he want to adopt such an inefficient method of self-improvement.

Therefore, he chose to cultivate two types of insects: one that could enhance his spiritual power through itself or its products, and the other that would assist in the physical transformation. He planned to cultivate them as food, consuming their products or bodies.

He chose the second option.

After six months of targeted cultivation, more than a dozen kinds of insects with strong vitality have differentiated in the petri dish.

These insects have been tested on mice and have indeed shown that they can improve physical fitness to some extent, but many problems still exist.

This time he has a thousand years and plans to use directed evolution for selection. These are not things that can be done overnight; they may even take several years.

While pondering, Yu Nu Zhicheng injected a certain amount of life energy into the petri dish to accelerate time and promote evolution.

Over thirty years, fifteen species of insects were completely eliminated in the course of evolution, leaving only five species capable of self-reproduction in this specific environment.

One hundred years later, a type of insect began to undergo reverse evolution. Its vital nutrients disappeared, and it evolved weapons such as armor and sharp forelimbs. It also began to fight for leadership of the insect swarm.

Since the evolution of life failed, Shisei Aburame could only manually erase it, restoring it to its original energy to minimize the loss.

Two hundred years later, the other four types of insects underwent irreversible mutations, no longer accumulating life energy, but instead began to arm themselves.

Aburame Shisei sighed, "It seems this targeted training has failed. But it's not a complete failure; at least I've managed to select five insects with training potential."

Just as he was preparing to change the environment, reintroduce the insects, and start over, all the insects in the petri dish experienced a large-scale physical breakdown at the same time.

To find out the cause, he stopped what he was doing and slowed down the flow of time.

It was discovered that an extremely tiny worm had been parasitizing the bodies of four other worms. Now, these worms had undergone some mutations, which caused them to collapse instantly.

These creatures have an extremely high reproductive capacity. After they die, they quickly invade other insect bodies. Most insects continue to collapse, and only a small portion undergo metamorphosis.

"Is this a special parasite that has differentiated itself?" Aburame Shisei frowned in thought.

But he quickly realized something was wrong; these weren't insects at all, but a virus derived from certain insect bodies.

With the acceleration of time, this virus iterates extremely rapidly, and the divine worms he originally cultivated have become unrecognizable under its influence: most of the worms devour each other and collapse, eventually leaving only two types.

One type consists of pairs of extremely small, soft-bodied parasites. Although their specific function is unclear, based on their appearance and the state of their chakra, they are most likely failures.

The other type is larger in size and has many insect-like features, resembling a hybrid product, but it contains rich life energy. It is currently uncertain what unknown changes it will bring after consumption.

In addition, there is the virus itself.

During its evolution, Yu Nu Zhicheng retained the original virus and stored it in one of the cells.

He didn't give up on the other two insects either, but placed them in two other slots, intending to test their effectiveness.

If it's useful, keep it and continue to study it; if it's not, just delete it.

The space inside the petri dish is then completely restored to energy, returning to its initial state.

At this point, the original energy in the petri dish was only a little over five hundred years old.
