The Sovereign Lord had other issues to deal with. A most pressing concern required his necessity to attend this tournament: he needed his wife to change her mindset about cultivation. He needed Li Meirong to practise diligently in order to attain godhood, and had even gone so far as to attempt to coerce her into joining this dull, boring mortal competition.
Furthermore, even if Li Meirong would win the tournament and acquire the pill, it would do her no good, since she wasn't at the right level to use it.
The reason which motivated his actions more than anything else, was his impatience. While he was known to be tolerant, when needed, when it came to his wife, he did not possess the patience required to wait for who knows how long for her to decide to achieve immortality.
