Green Meteor: Pangea Era

My name is Lu Chen and I live in Wuzhou. The endless land beneath our feet is now called Pangea. The older generation always talks about the old world - there were different continents, there were things called "countries", and there were clear borders. But since the green meteorite fell, everything was shattered. The continent was smashed into one piece, and borders, order, and civilization were all lost to the old world. Nowadays, there are meteorites everywhere, and the law of the jungle is the only way to survive. No one dared to go to the deep sea to find the meteorite that caused the accident. As time went by, it became a legend that no one had ever seen, only flickering in the old people's chats. I was just like everyone else in this wasteland, dawdling around and looking for a way to survive, until I repeatedly rubbed the old metal plate around my neck. The brand is made of matte black titanium steel, narrow and long. When my adoptive parents picked me up, they held it in my little baby fist. The word "Lu Chen" is engraved on the front, and the writing is thin and thin, as if it was written by someone. On the back corner, there is half a shallow and almost flat scratch of a sycamore leaf, as small as a speck of dust. I watched it for years. The name is mine, but who carved the words? What does the sycamore pattern mean? Why is it that every time my fingertips rub against the scratches, my heart feels empty for no reason, as if I have lost something very important. No one can give me the answer. Just like no one knows what is hidden in the legendary green meteorite deep in the far sea.
