This is My Heroic Path

An Zhiyu traveled to the Land of Shadows and trained with his master Skaha day after day, year after year. Later in the evening, at the end of the martial arts training, Morgan Le Fay taught him magic. At first, he and Morgan Le Fay got along very well. , which also gave him a good impression of Morgan Le Fay.
Until one day, Morgan Le Fay suddenly said to him: "It will be the time to choose the king in a week. My sister Arturia will draw the sword in the stone and become the king... I need your help with something."
"What?" An Zhiyu asked.
"Be one step ahead of her, pull out the sword in the stone, and marry her."
"???"
"The curse is launched, starting today, you must find a way to take Arturia as your wife!"
This is a world where time lines are intertwined. He has drawn the sword in the stone, solved the struggle between Skaha and his sister, and helped Gilgamesh. An Zhiyu thought he would continue to take risks like this.
Until one day, he was summoned by the Holy Grail.
Looking at the group of old acquaintances in front of him, An Zhiyu waved his hands awkwardly: "Hello..."
Arturia smiled and raised the holy spear in her hand:
"Shine on the spear of doom!"
