Starting with the Sword Ancestor System: Xiao Yan, Your Harem is Mine!

207: The yin is melted and the yang is forged, and the blade blank is initially solidified.The pure white earth core fire marrow, like a furious seraph, tightly enveloped the dark, deep nine nether cold iron that emitted a Soul-freezing Evil Qi.

”Hiss—!!!!”

Extreme heat and extreme cold, ultimate Yang and ultimate Yin, these two existences with completely opposite attributes but terrifyingly high energy levels, erupted in an unprecedented fierce conflict the moment they made contact!

It wasn’t a deafening explosion, but a more heart-pounding, insane annihilation and confrontation on an energy level! The white light of the earth core fire marrow and the faint light of the nine nether cold iron intertwined and eroded each other, emitting a strange sound, as if countless tiny ice crystals were thrown into a furnace, or as if billions of vengeful spirits were screaming in raging flames! A large amount of white steam and black smoke rose, which was an anomaly produced by the extreme consumption of energy.

The black platform trembled violently, and even the entire magma lake below it churned endlessly!

Li Ao stood at the center of the storm, his expression as solemn as water. His hand seals changed like flying, and his Soul Power poured out with unprecedented intensity, like the most precise controller, firmly restraining the violent earth core fire marrow, precisely concentrating its heat and destructiveness on the nine nether cold iron, ensuring that it would melt while also preventing the Yin-cold Evil Qi from being completely incinerated by the ultimate Yang fire.

This was an extremely dangerous balance. If the heat was slightly weaker, the nine nether cold iron would not melt; if the heat was slightly stronger, the Evil Qi would be completely lost, and the nine nether cold iron would become ordinary iron.

Veins bulged on his forehead, and beads of sweat were instantly evaporated by the terrifying high temperature as soon as they seeped out. The nirvana star core rotated at an unprecedented speed within his Qi Sea, continuously providing pure Nirvana Power. This power was not used for destruction at this moment, but as a supreme ”rule” power, forcibly intervening in the conflict between the Fierywhite and the faint dark, harmonizing, suppressing, and guiding the two towards an incredible—Fusion!

Gray-gold Qi flow spread out from Li Ao’s body, like a third force, wrapping around the core of the fiercely conflicting energy.

Time seemed to become thick and slow at this moment.

One hour, two hours... Under Li Ao’s relentless consumption of Soul Power and Nirvana Power, the fierce confrontation finally gradually subsided. The indestructible form of the nine nether cold iron, under the continuous scorching of the earth core fire marrow, began to slowly soften and deform at the edges, like solid ice encountering warm sunlight, seeping out tiny drops of dark black liquid.

These liquid drops were not evaporated by the flames, but instead, as if possessing life, flowed slowly under the guidance of the gray-gold Qi flow. The Yin-cold Evil Qi within them was perfectly preserved, and even became more pure and concentrated under the refining of the extreme high temperature!

The smelting was progressing towards success!

But Li Ao dared not relax in the slightest. He carefully controlled the process, adding auxiliary Materials used to stabilize the energy structure into the gradually melting dark black liquid according to a specific sequence and proportion.

”void crystal stone”, transformed into specks of silver light, merged into it, imbuing it with an affinity for space.

”Earth Mother Qi”, like a wisp of condensed yellow flowing light, seeped in, increasing its profoundness and toughness.

Various rare auxiliary Materials, one after another, transformed into pure medicinal power or energy flow, harmonizing the conflicts between the main Materials and stabilizing the structure of the Saber embryo that was about to take shape.

Another long hour passed.
