Gu Qihang is the son of Gu Yu's lover.
Gu Qihang never calls Gu Yu father, only uncle.
Later, when Uncle Gu got older, he was confessed by Gu Qihang.
When he collapsed, an accident sent him to a mysterious ancient country. Gu Yu became the only surviving prince besides the emperor in this ancient country.
The skills he had developed over thousands of years are now put to use here.
History was full of ups and downs, the palace was turbulent, and everything about the dynasty subverted Gu Yu's imagination.
Walking through the bustling place, there is only this sound in my memory.
"Uncle, I like you."
"Uncle, I really like you."
"I've liked you for a long, long time."
…
The child once held his hand and walked forward step by step.
Yes, no matter how difficult, complicated or dark the future is, those bright moments still exist in the memory and gradually take root.
