Hymn of Sincerity

AI Blue Whale's cold voice continued to sound in Su Yu's ear:

"The actual timeline goes like this:

A year and a half ago, the Skrull people defeated the Blue Star Humans and became the winners of the Civilization Ascension Project.

But this was just one of the countless battles among lower civilizations and didn't catch the hymn's attention.

At the moment of your death, space-time suddenly reverted! Time returned to one year before the war, and everything on both planets reverted to the state they were in at that time!

Even Donna and Lin Ke, the siblings, were not exempt.

Donna and Lin Ke were originally planning to return to the academy to report on their duties, but because of the time reversal, they found themselves back to a year and a half earlier, just like when they first arrived on the Blue Star.

This situation, of course, caught the attention of the hymn, who then speculated that a four-dimensional space-time creature must have been born.
