Su Yu's eyes flickered. "Let's first make the exchange. As for how many strikes of disastrous thunder it can withstand, you can test that afterwards as you please."
Zi Qianchou nodded at him, then stood with the other two Divine Masters between Su Yu and Gu Taixu. From this action alone, it could be seen how wary he was of him.

Gu Taixu believed that Su Yu would surely return to the Jiuzhou Continent's Mysterious Heavenly Stage. After he returned there, with Gu Taixu's current strength, which was at the later stage of the Divine Master Realm, he wouldn't be able to obstruct him if he wanted to steal the blood of a Real Dragon.
Moreover, they still had an important task that they hadn't yet accomplished. That was regarding the divine egg of a Real Spirit that the Divine Master Tu Mo had stolen.
