Let You Compete for the Holy Grail and You Raise Pigs in Einzbern

[Shape Moon + Steel Refining + Farming + Relaxing and Cool Writing + Invincible Flow] "If you want to get something, you must pay the same price." This is the truth that Linn learned in that world full of alchemists. But when he opened his eyes again, he found that he had turned into a stone shining with scarlet light, and was being held tightly in the palm of a little loli with silver hair and red eyes. This is Fuyuki City, on the eve of the Fifth Holy Grail War. The little loli in front of me is Illya, a tragic girl who is destined to become the container of the Holy Grail and die. Lin En smiled. As a genius who had made the "Philosopher's Stone", he decided to rewrite everything. Not enough magic power? It doesn't matter, buy a pig farm next door, the souls of three thousand pigs are enough to activate a forbidden refinement! Body collapse? It's a small problem, I've perfected the human body to ensure you live a long life! Jin Shining Who is that? Can you withstand my particle cannon that compresses the souls of 50,000 pigs? Looking at the stunned Emiya Shirou and Tohsaka Rin, Lin En controlled the red stone to float in the air: "Don't get me wrong, we are not here to compete for the Holy Grail, we are here to teach you what 'scientific cultivation of immortality' is."
