Seeking a novel title

I only remember a few scenes:
It's a time-travel novel
[Fragment: The main character competed with a woman dressed as a man. In the end, the main character won with a dolphin voice. Then, a woman competed with the main character in a dance competition. In the end, the main character won with M's space dance. Can anyone remember the name of this novel?]
This novel is a kind of sh * t transmigration novel.
The protagonist had traveled through another world, not the modern world.
There was also the main character who sold things with a red-robed cardinal from the Holy See. In the end, the red-robed main character became the Pope with the money he earned from selling things.

Answer 1

Do you want the title of the novel to be 'Tower of God'? If so, it was a Korean story about a fantasy world called "Tower" between humans and beasts. The novel was published in 2011 and received widespread praise.
