Infinite Manifestation: My Soldiers Are Impossible to Kill

[Apocalypse + Unlimited Soldiers + System + Invasion + Skills] After losing his loved ones while trying to help someone in need, Qin Han finds himself powerless to avenge them against his enemy's overwhelming power. Then the apocalypse breaks out, and a mysterious Military Lord interface appears in his mind, giving him hope for revenge: [Reservist] [Spearman] [Greatsword Infantry] [Sword-and-Shield Infantry] [Heavy Infantry]… A million zombies are a lot? My soldiers… outnumber them. There are too many kinds of enemies? My soldiers… come in even more varieties. (Soldier summons are limited early on. The author will address this around chapter 100.)
