Freshly Switched to Summoner: Unlimited Summoning Space from the Start

[Everyone changes class + fast-paced + wish fulfillment + comedy + ensemble cast + System + invincible protagonist] [Guided by a summoner, with no baseless assumptions and rigorous data] Beast hordes invaded, the world underwent a transformation, and everyone entered the age of class changes! Chen Yuan changed into the universally mocked class of [Undead Summoner]. Summons stabbing him in the back? Awaken [Absolute Loyalty]: his summons will never betray him! Not enough space? Awaken [Infinite Space]: his summoning space can hold an unlimited number of summons! Too fragile? Awaken [Shared Fates]: all damage he takes is divided among his summons! When truly indescribable outsiders arrived, all of Huaxia was plunged into crisis. Yet one person stepped forward. “When I descend... death will no longer be the end. It will be the starting point of my army.”
