My Basic Attacks Summon Undead: I'm the Dark Ranger, the Real Calamity

The short version: There are two buttons in front of you. Press the button on the left, and you can become a necromancer who summons undead with basic attacks, but has a very slow attack speed. Press the button on the right, and you can become a marksman with an extremely high rate of fire who shoots volleys of multishot arrows. “Only children have to choose. I want both!” You press both buttons at once. Congratulations, you’ve become a cheat-level powerhouse with an extremely high basic attack speed, capable of firing multishot volleys that summon vast undead armies! The full version: The world goes digital, games descend into reality, monsters run rampant, and the era of class advancement begins! When people awaken, they all have a chance to receive a random class badge and a piece of exclusive equipment. After being reborn, Chen Mo traded his SSS-rank class for an S-rank class that, in the eyes of others, seemed mediocre. It belonged to a young lady from a prominent family in his class! What no one knew was that this S-rank class, paired with Chen Mo’s exclusive equipment, could unleash limitless potential. The Dark Ranger class talent lets him enchant arrows with dark skill books. Firing an arrow releases the enchanted skill, but the effect is consumed after one use. Chen Mo’s exclusive equipment, the Endless Quiver, can record any arrow and copy it without limit. Enchant an arrow with [Undead Summoning], and every basic attack becomes a summoning skill! While others are still discussing how to balance their team’s classes, he has already summoned a densely packed skeleton army on his own and swept through dungeons! While others are still arranging their troops to defend the city, he looses a rain of arrows, and a vast army of dark wyverns fills the sky. One blast from their gaping mouths unleashes countless dragon breaths of death, devastating the battlefield more terribly than any forbidden spell!
