Starting Weapon System! Bringing My Sister-in-law to the End of the World

[Apocalyptic underworld + hegemony + sister-in-law at the beginning + modern warfare + zombies + system + no rebirth + many beauties + decisive killing + no superpowers but evolution.

[The underworld style of the end of the world, first the rivers and lakes and then the hegemony, invincible without abuse. 】

A mysterious blue fog enveloped the cities of Blue Star, order collapsed and zombies were rampant. Three years after the catastrophe.

After overcoming the initial chaos, humans launched a counterattack against the zombies.

Qi Shikai, a man of swords and guns from the Northeast, rose up in the end times with his sister-in-law.

Faced with the bully who wanted to seize his sister-in-law, Qi Shikai awakened his weapon manufacturing system.

[Ding! Reward weapon blueprint - inferior rapid-fire shotgun.]

[Ding! Reward ammunition blueprint - 12-gauge shotgun bullets.]

[Ding! Reward weapon blueprint - m1911a1 pistol. ]

[Ding! Reward ammunition blueprint - .45 pistol bullet. ]

[Ding! Reward grenade blueprint - Type 67 grenade.]

[Ding! Reward explosive blueprint - black powder.]

Faced with the increasingly powerful system, Qi Shikai's eyes showed excitement.

There are people, food, guns, and loyal brothers.

Qi Shikai said that I was timid before I had the system, but after I had the system, I struck hard.

When all human forces were still fighting in retro and modern modes, Qi Shikai made a brilliant appearance.

Please wait a moment.

What are those swarms of drones all over the sky?

Why is there still a steel torrent?

Is this a mechanical tiger?

There is Gundam!

What happened to Star Wars?

Qi Shikai - The end of the world gave me a pair of eyes, and I use the system to find light.
