950 Yin and Yang grinding plate

Taichu, Dutian, Pure Yang, and the Yuan Tu and Abi swords of the Ancestor of the Underworld River were placed together by Jiang Chen, allowing these five top-tier Innate Slaughtering Swords to sharpen each other and refine their sharpness, enhancing their power.

The supreme Sword Realm around Jiang Chen was exactly the place where these five Innate Slaughtering Swords refined their sharpness.

For hundreds of years, the five swords mutually honed one another, and their sword intent had already escalated to a terrifying level, flowing with a sense of flawless smoothness, indicating they had reached the realm of the Daluo Jinxian of the Primordial.

As the Sword Realm evolved to this point, it was almost becoming Jiang Chen's greatest method of killing, with the current unsurpassed sharpness of the five swords, even a Daluo Jinxian of the Primordial who fell into the realm would be slain and turned into ashes.
