Although the Lord of the Universe said he could attack Ling Tian at any moment, he didn't actually make a move. He also promised not to burn his soul after being defeated, which was an unexpected boon for Ling Tian.
It made sense. Ling Tian had always been quite interested in the Lord of the Star Domain. He knew very well that after defeating the Lord of the Universe and obtaining Guixu, he would inevitably come into conflict with the Lord of the Star Domain.

Since the Lord of the Universe had promised not to burn his soul, Ling Tian could learn about the Lord of the Star Domain by searching his soul or fusing with it.
Even if Ling Tian and the others had a chance to defeat the Lord of the Universe, it would still be easy for him to burn his soul or even self-destruct. Ling Tian and the others might not have any chance at all to stop him. If that happened, they naturally wouldn't be able to learn about the Lord of the Star Domain from him. Now that the Lord of the Universe had promised not to burn his soul, that was undoubtedly an unexpected boon for Ling Tian.
