The tribulation lightning was terrifying, and the lightning tribulation unleashed by the Lord of the Universe possessed the power to destroy heaven and earth. Even now, while the Lord of the Universe was weakened, his lightning tribulation was more than Sky-Breaking Bow could withstand, even if the latter recovered to his peak.

After all, the Artifact Spirit dwells within the material. With the material protecting him, he'll take much less damage," Su Ying suddenly said.

Seeing the amused expressions on Ling Tian and the others' faces, Sky-Breaking Bow added meekly, "Of course, lightning-attribute materials are difficult to refine, so fusing them in might be a little tricky. But the Essence of Thunder is a different matter. If I absorb it slowly and refine
