Actually, even without the Artifact Peak Master's invitation, Ying Huaixu would have ground out his Artifact Refining level.
He needed Artifact Refining proficiency for many of the custom Magic Treasures he would make later.
Even back when he had farmed for money, most of his income had come from custom magical equipment.
Every instance and raid had been about farming materials for custom crafting.
Some good custom Magic Treasures or pieces of magical equipment could even sell for millions or tens of millions.
A Magic Treasure with no level requirement and three empty affix slots would sell for an astronomical price.
Ying Huaixu had wanted to grind all along, but Artifact Refining Peak had always been packed.
Now he finally had a chance to grind some proficiency.
At that thought, Ying Huaixu started taking off his shirt.
But the Peak Lord stopped him.
"Sister Ying, isn't this a bit inappropriate?"
Ying Huaixu: "???"
"Are you fucking sick in the head? The Artifact Refining Room is that hot, and you expect me to go in with my shirt on? And why the hell are you blushing? I'm a man!"
The Peak Lord froze, then coughed. "Oh, right. It's mainly because your looks are a little too striking, and everyone calls you Sister Ying. I forgot for a moment."
Ying Huaixu took off his shirt, revealing muscles that were not particularly chiseled but well-proportioned, and rolled his eyes as he walked toward the Artifact Refining Room.
As it turned out, Artifact Refining was even easier than Ying Huaixu had imagined.
"The system gives instructions the whole way. Three strikes with the small hammer, five with the big hammer, add..."
"Clink, clink, clang, clang, clang, clink, clink..."
A string of hammer strikes rang out, and Ying Huaixu soon crafted a low-grade magical longsword.
