The End of the World: the Iron-Blooded Order Listens to My Orders

[Apocalypse ➕ Zombies ➕ System ➕ Explosive Soldiers ➕ No Heroine ➕ Civilization] Bloody meteors pierced the sky, electronic equipment around the world was instantly paralyzed, and zombie viruses swept through human civilization like a tsunami. The once prosperous city has turned into a devouring hell, and the survivors are struggling to survive in despair. Lu Chen accidentally awakened the "summoning system". The initial summons, only one squad of fully armed infantry, became his first line of defense in the wasteland. From sporadic firepower to clusters of heavy weapons, from squad size to torrent of steel, Lu Chen used orders as a blade and summoned troops as a shield. In the end of the world where zombies and mutated creatures are rampant, he will build a fortress of human survival step by step, making "obey my orders" the most awe-inspiring declaration in the wasteland.
