Plop—

Ronald sat on the ground, feeling as if everything had lost its flavor, not even interested in the newly acquired original manuscript in his hand.

Uncomfortable.

It was too uncomfortable!

Though there wasn't any material loss, the mental blow was undeniably painful.

He was so close, himself...

"Sigh—"

Ronald couldn't help but let out a deep sigh.

Though he felt uneasy, the innocent citizens of Capen were truly blameless. So, quickly gathering his emotions, Ronald flipped open the not-too-thick thesis and read the contents of the first page aloud:

"In order to acquire new color variations for ornamental plants through artificial fertilization experience, the experiments discussed herein were initiated..."

The magic power of the original manuscript was drawn out by the incantation, and Ronald immediately understood the spell of the "Plant Hybridization Experiment". 𝙛𝒓𝒆𝙚𝒘𝒆𝓫𝙣𝓸𝙫𝓮𝒍.𝒄𝒐𝓶

The abilities provided by this original manuscript were surprisingly simple, with only two spells that matched the two stages of the manuscript trial.

——[Separation Law]

Using this spell on a selected target, one can deeply unearth the hidden traits within the target's genes and fully manifest them. Even if the caster ceases to interfere afterward, the manifested characteristics will remain permanently.

——[Free Combination Law]

This spell allows the selection of two target creatures, freely combining their genes to achieve a species optimized to a great extent, enabling the caster to manipulate the spell's target.

Besides, just like the [Separation Law], this spell can also have a permanent effect on the spell target.

"..."

"These two spells."

"Really overlap significantly with 'Origin of Species'."

Perceiving the effects of the spells, Ronald quietly exclaimed.

These two spells respectively correspond to the gene separation law and the independent assortment law from the three fundamental laws of genetics, coinciding with Mendel's ideas from the "Plant Hybridization Experiment".

Furthermore, as Ronald had previously thought.

The genetic modification capabilities provided by "Plant Hybridization Experiment" can also be accomplished by "Origin of Species", and can even surpass it through evolutionary advantages.

Only one point—

[Free Combination Law], due to the factor of human interference, added an extra effect to manipulate the spell's target, which is something "Origin of Species" cannot achieve well.

At this point, Ronald's gaze shifted again to the corpse at his feet.

The capabilities of the "Plant Hybridization Experiment" spell have already explained the reason behind those sea creatures' attacks on the city of Capen. Now to solve the problem, Ronald only needed to do something quite simple.

"Come forth—"

A light command, and the corpse on the ground instantly flew into Ronald's hand.

With the combined abilities of the "Origin of Species" and "Plant Hybridization Experiment" original manuscripts, Ronald quickly determined the situation.

The deceased caster actually had a very gentle character, so his control over the sea creatures was maintained at a low level. After discovering these rapidly evolving creatures in the ocean, he aimed to help them grow together.

So in the process of helping these marine creatures evolve, he strengthened their nature of advancing and retreating together, caring for each other.

But he never expected.

With the restraint of [Twelve Witches' Assembly], the people of [Dawn Spell Society] still acted so viciously, aiming to kill him and seize the original manuscript.

Then the caster died, and the parasitic body survived.

Left with only vengeful thoughts, the host triggered everything and transmitted information to the sea depths, intensifying the sea creatures' trait of advancing together, and then using interference capabilities to direct the revenge target towards human cities.

"..."

Strictly speaking, this was already a deadlock.

The enraged emotions, the gene-deep influence, and the number of sea creatures nurtured by the original manuscript holder during his time in the ocean.

These nearly unsolvable problems.

The only way out is for the human side to completely exhaust these vengeful beasts, ending everything with one side being annihilated.

But alas, the person standing here was Ronald.

And he possessed the "Origin of Species", able to modify the stabilized genes again, fundamentally changing this life-and-death situation.

Thus, upon deep inspection, Ronald's expression turned helpless once again.

While he began modifying the genes just obtained.

Ronald simultaneously flew into the air and returned to Capen, muttering:

"First pollinate the plants, then transform the animals."

"Today I just can't seem to get past this heavy labor work!"

"..."

And so, in the rainy night, a silhouette returned to the seaside.

Unnoticed by anyone, Ronald dove into the depths of the sea, relying on his perfect adaptability to restructure the state of each sea creature.

Indeed, this counted as luck.

If the sea creatures attacked the city purely due to vengeful emotions, Ronald's efforts wouldn't change the situation no matter what.

But as long as there was a genetic issue, once the restructuring was complete, there remained a chance for reversal.

...

Meanwhile, the night rain fell heavier.

The casters at Capen Port make every effort to maintain the defense, coming close to utter collapse several times.

Fortunately, they had Costate's aid.

This maid, despite acting alone, was able to summon a powerful flame as if reversing the weather, effectively restraining these aquatic species sea creatures.

Defenders retreat, Costate steps up.

Defenders regroup, Costate quietly retreats to the rear.

In this mental destroying tug-of-war, when a faint glimmer appeared in the cloudy sky, someone finally joyfully discovered—the sea creatures' attack had ceased!

The previously fast-spinning seawater gradually slowed down and visibly calmed. More wonderfully, the endless stream of sea creatures emerging from the water now stopped.

A common thought arose in people's hearts—

The battle... has ended?

And at this moment at the port, Il's figure quietly appeared behind Costate.

This 'girl', who had helped transfer residents all night, showed no sign of fatigue, instead contently hugging Costate from behind.

"Morning, Costate~~"

"I watched your performance last night from the rear, it was amazing!"

Costate shook her head.

The maid, observing the crowd who survived the calamity, contemplated with a unique brilliance in her eyes. Nonetheless, she couldn't refrain from speaking as usual:

"No, Il, this was the master's doing."

"I was here, only doing a very tiny job."
