Eren's spirit beast was a blue-scaled fish.
It was a distinctive blue-scaled fish that resembled a salmon, except for its horned head and large size.
Measuring approximately a meter in length, the fish possessed a dainty physique and exuded an alluring aura when motionless. Its movements in the water were graceful and captivating to observe.
The fish appeared to possess a body made of mana, yet its mana signatures resembled those of a living organism. One could only define it as a conscious fragment of the world's will.
The spirit beast would seek the Red Fire generated by the Red Fire Sardines before devouring it as if it was the most delicious fish food. Of course, the spirit beast didn't hurt the Red Fire Sardines while devouring their flames.
It seemed that the Red Fire Sardines could also understand that the spirit beast meant them no harm. And that he was part of something that bore no ill will toward them. As a result, the Red Fire Sardines started swimming around the horned spirit beast, offering him plenty of red fire to digest.
And as the spirit beast shared a connection with Eren, the secrets behind the Red Fire's creation were also being processed by Eren.
By the time he ejaculated deep inside Nysa, he had strengthened his fire-element abilities in a new way. The butcher also unlocked the elemental fusion of fire and water because of this unique experience.

Fire and water were two opposing forces of nature. Unlocking an elemental fusion between them should have been impossible for a mere Expert ranker like him. Yet, Eren managed to do that, thanks to the conscious fragment of the world's will.
Eren was inspired by Red Fire Sardines' inherent abilities. But what he unlocked was not a simple elemental fusion. Rather, it was a compound elemental fusion.
The butcher couldn't achieve the elemental fusion of fire and water normally found in the Red Fire Sardines. He couldn't follow their examples to a T. His elemental attainments as an Expert ranker were still lacking to fuse the two opposing elements together.
Therefore, Eren introduced a third element into the equation that could act as a mediator between the two opposing elements and keep them together. Of course, this element was the space element.
Eren's space element attainments had just seen a huge boost, thanks to his mating with Nysa under Mist of Lust. Plus, his experience of unlocking compound elemental fusion was still fresh. This was something he had unlocked while dueling with Demonmir at the Edinnica Arena.
As a result of all of these factors, Eren was able to unlock another compound elemental fusion for himself. One could say that Eren received another blessing from the river Lithe just by being near it.
Eren's spirit beast disappeared silently. It left no traces of its existence in the River Lithe.

Freya was ruined.
It almost looked like an underwater ghost ship with its torn furls, broken mast, and destroyed deck. The only two passengers aboard, however, were too busy to care about the ship's well-being.
Eren was seen lying on a water bed. Nysa rested her head on his chest, listening to his calm heartbeat.
The butcher smiled, his eyes closed in deep thought. He had quietly absorbed his gains. When he thought he was ready, Eren raised his right hand and channeled his mana.
A red flame danced over his forefinger. This flame had a higher potential than normal flames while carrying liquid properties. It was as if a droplet of water had been injected with condensed fire before being hammered to act like a flame.
Eren's red flame had an additional property. It could integrate itself with spatial layers, intermittently disappearing from the naked eye.
Eren could tell that the new compound elemental fusion he had unlocked could play a significant role in countering the Enderflames. His blue fire could absorb the heat, giving him a way of defending himself against the Enderflames. Red flames, however, could be a viable offense due to their combination of elements. Since they also included the Way of Water in their creation, these flames would be difficult to counter with water-based spells and attainments alone.
Eren could use the two flames intermittently for his offense and defense. Or he could find a way to incorporate them together in his battle style. This would make him one of the greatest fire element specialists the land of Anfang had ever seen.
Breakthrough into the Expert rank. Various Abilities and elemental attainments are obtained in the Sansara World. The Sage Legacies. And lastly, these fusion Red Flames. The butcher had made a lot of progress since he left White Raven to come to the capital city. He needed to consolidate these gains at this point.
Nysa felt the red aqua flame's distinct mana pulse and opened her eyes to learn about its origins. She was shocked to see Eren had unlocked a compound elemental fusion for himself during their underwater time.
Nysa could feel that Eren's red flames were inspired by the Red Fire Sardines swimming around the ship. But they were not the same. She could also feel some familiarity with the flame because of the way it incorporated the space-element attainments.
"Those... those are my spatial attainments. How did you do that?"
Eren smiled when he heard Nysa's question. He chuckled before replying cryptically.
"How indeed. Kekeke. I guess I'll have to thank you properly for this."
Eren declared before getting on top of Nysa again. The latter welcomed him by spreading her arms, wrapping her legs around his waist again.
The couple spent quite some time together, lost in each other's company. Freya returned to the surface two days after her supposed disappearance, poor and battered.
Eren and Nysa both received a notification message on their spectral screens when they decided to show themselves in Edin again. It was related to their commencement ceremony.
The ceremony was to be held in a week and it was only natural that they'd be invited.
