Yuchi Hanqing, standing before the golden gates, flushed. Of course, she could tell that Jiang Feng was deeply dissatisfied with this key.
And this key just happened to be one she had forged.
As the most proficient artifact refiner in the ruins, she had never imagined that her work would fail to catch Jiang Feng's eye.
Jiang Feng examined several more keys in succession. These were even worse—simply too ghastly to look at.
After looking them over, Jiang Feng had roughly understood.
Whether they could leave the ruins hinged on the keys. And the key to forging those keys lay in the colossal sword held by the statue—the inscriptions on it were the crucial point!
Clearly, Master Yungang and the others had realized this long ago, which was why they had never given up on using the giant sword's inscriptions as a breakthrough to forge keys. But with their method of refinement, they would never succeed even in a lifetime.
Master Yungang could also see that Jiang Feng had already grasped the crux of the matter. He spoke up:
"As long as we can forge this key, we can activate the core hub. Though we do not know what will happen then, one thing is certain: Heavenly God Burial will collapse."
"Then we will have a chance to leave this place!"
"However, this key is not easy to forge!"
"I have calculated that this key should be a spirit artifact, yet despite all our efforts over so long, we have not even touched the threshold of forging spirit artifacts."
"You possess two spirit artifacts. Given your cultivation and the environment you were in, it would have been impossible for you to obtain spirit artifacts elsewhere. Therefore, I deduced that you must be capable of forging spirit artifacts."
Jiang Feng smiled
