Northern heaven cold star Iron

“嗞! Northern heaven frigid Star Iron! It's actually the northern heaven frigid Star Iron!"

When Yunxiao discovered the material of the pillar, the shock in his heart was even greater than freezing his soul. He was so shocked that his eyes almost fell out of his head!

"W-what? This is the northern heaven frigid Star Iron? You're not joking, are you?"

Yuan gaohan was also startled and hurriedly came forward to check it carefully. He immediately sucked in a few breaths of cold air and felt that he couldn't stand steadily.

He looked at these seven towering stone pillars in a daze. They actually contained ninth-tier materials that were extremely difficult to find in the world.

That was something that could be refined into a ninth tier profound armament as long as it was the size of a fist!
