"Thank you!"
Zhou Tian was not an ungrateful person. Even though the other party owed him a debt of gratitude, Zhou Tian wouldn't exploit his "benefactor's" status to make unreasonable demands. After all, Zhou Tian knew that while his benefactor was a person who valued repayment, someone who had reached the current level that individual had must not be naïve or simple-minded. Even if that Deity genuinely intended to repay him, it did not necessarily mean they would tolerate all of Zhou Tian's requests.
Therefore, although he didn't have any special motives, when facing the Deity, Zhou Tian still instinctively placed himself in a lower position.
In truth, Zhou Tian's deference at that time wasn't just because he realized his status and strength were inferior to that of the Deity. The imposing presence of the Deity itself played a considerable role in influencing Zhou Tian's behavior.
