In a 100-Level Underground Otherworld, I Solo as a Necromancer

A passage to an underground world opens, and humanity enters the age of supernatural abilities.

Zhang Yifan gains a Growth System and changes class to become a Necromancer. Monsters he kills are summoned to fight for him.

He kills a Goblin King and summons an elite Goblin King boss.

"Its stats are actually twice as high as an ordinary goblin's!"

He kills the Hell Lord Diabaton and summons a rare elite Hell Lord Diabaton boss.

"Its stats are actually twenty times higher than those of others at the same level!"

A passing adventuring party: "We heard that big shot fought his way through the 75th floor alone. I can't imagine how he manages without teammates."

The Demon King's Guards on the 99th floor: "General, our ten-thousand-strong army has been crushed by a human leading twenty monsters! We request reinforcements!"

On the 100th floor, the Demon King kneels before Zhang Yifan, begging desperately.

"Please, don't open that door!"
