I Accidentally Killed an Immortal Emperor from the Start, Now I Sell Weapons in the Immortal Realm

[Technological Weapons + Cultivation + Uncomplicated Wish Fulfillment + No Saintly Heroics + No Female Lead]

Ye Heng transmigrates to the Immortal Realm and awakens a sign-in System, but the System traps him inside the Guardian Pavilion. It claims it must protect its Host and that he can only leave once he reaches the Mahayana Stage.

At first glance, that seems reasonable. But what on earth are these System rewards?

First day of sign-in: Desert Eagle.

Second day of sign-in: AK-47.

Third day of sign-in: 98k.

Fourth day of sign-in: grenade launcher.

As he keeps signing in, he receives all kinds of modern weapons, including a heap of hydrogen bombs and nuclear bombs. But what do any of these have to do with cultivation? Without even a single cultivation manual, how is he supposed to cultivate? How can he reach the Mahayana Stage?

Then, by pure chance, Ye Heng accidentally takes down the Flame Emperor with a Barrett. Only then does he realize just how powerful these weapons are!

An idea occurs to Ye Heng: he can sell these weapons to immortals in exchange for cultivation resources!

But how can he let the outside world know? First, he’ll set off a hydrogen bomb to give the Immortal Realm a little shock!

What does it matter if the world is engulfed in war? I just want to grow my business bigger and stronger!

At my shop,

with enough money, you can get weapons capable of killing an Immortal Emperor!
