Chapter 400: System's Merged World - 6

It wasn't the drastic change they expected for level sixteen, but as he observed the new interactions, Elio understood that this "small" world still held surprises, each new element adding its own signature to the complex chemical dance surrounding him.

The tunnel descent proved almost routine. 

After handling potassium and studying sodium's reactions in the outer world, the reactive barriers barely presented a challenge. 

The new element behaved similarly to its predecessor but with more predictable, controlled reactions. Each barrier dissolved with precision, a testament to Elio's growing mastery over these chemical interactions.

The real surprise awaited in the final chamber.

They had doubled indeed.

Two thousand forty-eight creatures awaited him, their long curved necks and brilliant white feathers reflecting light as if crafted from pure sodium.
