Alien Invasion, I Use My Sickle to Protect the World

Six thousand years ago, meteorites fell, greed tore the seal, the void eroded, and alien species ran rampant! Human civilization staggered forward in blood and fire. It was thousands of gods who fought with blood and temporarily stabilized the shaky seal. In the twentieth century, the seal is broken again, and the end of the world is coming! Ordinary people are completely unaware, but only those who have awakened their powers bear the burden of the survival of the race. Xie Tianlan, codenamed "Shadow Scythe", was originally a mote of dust, but unexpectedly became the sole successor of the ancient god of death. He started with a scythe and possessed the power of shadow. Starting as a G-level rookie, he has experienced the bloody battle in the Bohai Sea, the desperate situation in Iceland, and the defense of the Great Wall... He has been tempered in the sea of ​​​​blood and corpses, and has broken through on the edge of life and death! When the S-class falls, the Great Wall is in danger, and Antarctica ends! Can he collect the five runes, reactivate the ancient seal, and use his mortal body to kill all the gods, demons, and alien species? This is an epic about courage, sacrifice and inheritance, a sickle-wielder who cuts the path to the dawn of mankind in the apocalypse! (PS: The protagonist appears in Chapter 6. The first five chapters are the prologue and the plot of the heroine. Readers who don't like it can skip it)
