Link focused on the phrase "the end and the beginning anew, all things renewed."
The lifespan of Sage Michelle was coming to an end, which could very well be described as "the end."
If, with the help of the Immortal God Tomorrow Court, Great Sage Michelle managed to change his cultivation path and successfully ascend, that would be "the beginning anew."
Everything would then be "all things renewed."
So, Lotson was reminding Link that today and tomorrow were the most important days for Great Sage Michelle.
In the calendar of the original World of the Immortal Gods, where the tradition of "celebrating the new year" began, today is nothing special, but tomorrow is New Year's Eve, or what is commonly referred to as "the great year."
From this perspective, the day when Great Sage Michelle completes his ascension must be tomorrow!
