Collapse of Iron: Summon Xi Lian at the Beginning to Participate in the Holy Grail War

I, a time-traveling pioneer, woke up in the strange Holy Grail War, and the "Archer" class lighted up on the back of my hand. The summoned servant Xi Lian is gentle and powerful, but always shows a familiarity that spans time in his conversations. I thought this was just a life-and-death survival game among seven groups of masters, dealing with powerful enemies such as sand gold, black towers, and Rakshasa. Until I paid all the price, defeated miserably and made a wish to "end the war", the Holy Grail disappeared, and Xi Lian turned into a point of light in the kiss goodbye. ——I actually returned to before the war started with all my memories. But this time, the command spell on the back of my hand was "Berserker", and it was no longer her who was being summoned. When the robin's call for peace resounded through the city again, I knew that I must use this foresight to reverse everyone's tragedy and find her who saved my memory time and time again in endless reincarnations.
