I Merged with the BOSS Body

Lin En only wanted to be an ordinary doctor in the apocalypse, until he cut open his own chest and discovered that beating inside was a golden heart from a legendary monster. From then on, the weak doctor became the fat in the eyes of all forces. The Iron Slayer Guild wants to investigate him, the black marketeers want to take advantage of him, and the iron skeletons outside the city wall seem to be particularly "enthusiastic" about him. In order to survive, he picked up the scalpel and began to perform the most dangerous operation on himself—— Put those fatal things into your body one by one. While others were still struggling against the erosion of iron, Lin En had been silently dismantling the strongest monster and calmly transforming himself into a dangerous weapon in the world.
