章 381: Chapter 374: Trouble_1

As a Grandmaster Refiner, Su Xin could tell that Gongshu Yu also possessed the strength at the peak of the Divinity Transformation Realm.

Of course, as a Grandmaster Refiner, strength also guarantees a part of the artifact refining process.

Since ancient times, a powerful martial artist may not necessarily be a formidable Grandmaster Refiner, but a Grandmaster Refiner must certainly be a powerful martial artist.

If that were not the case, Gongshu Yu's act of increasing the temperature of the furnace would be untenable without a strong inner strength foundation.

Moreover, if your strength is weak, you would never be able to forge a sword like Gongshu Yu does, swinging a hundred-thousand-pound hammer.

Furthermore, for some swordsmiths, if you don't understand swords, how can you create them? Therefore, every great grandmaster refiner who has researched sword forging rigorously is a master of Sword Tao, just like Li Daoan.
