Chapitre 713: Chapter 713: The Celestial Clan's Arrangement, Infinitely Close to Sacred Arms

Thunder Palace!

This was the top-level spiritual treasure that Ye Feng was about to craft.

It wasn't a Sacred Arms, and as for the exact grade of spiritual treasure it was, even Ye Feng himself wasn't quite sure.

He felt that it had to be at least a Four Star transcendent spirit treasure.

If it weren't for everyone's help, as well as a Heavenly Dao Remnant's gift of an Origin of Heavenly Tribulation, he would have had no confidence in crafting such a supreme grade treasure.

Having inscribed these three characters, Ye Feng continued to inscribe.

He drew a pattern-like rune in mid-air, then led molten refining materials over and fused them with the pattern-like rune.

Crackle!

In an instant, lightning flashed, causing everyone's faces to change.

"It's worthy of being the Thunder Palace, even though it's a Heavenly Dao object of inferior quality, even just a single rune contains immense lightning energy," whispered an old artifact refiner from the Divine Map Mountain Range.
