Start with a dumb system and travel back and forth to another world

A missing grandfather, a father in an accident, a mother forced to death, and only a broken him is left!

Jiang Fan's life had been unhappy ever since the misfortune at home, until he accidentally obtained a system that opened the passage to another world!

From then on, he embarked on a strange life of reselling goods between the two worlds, and the gears of fate began to turn!

He constantly obtains the items he needs from the two worlds and exchanges them for resources that can improve his strength!

As all the mysteries of the past are revealed one by one, the enemy is right in front of us, and new and old grudges are settled together!

Bullying me because I am weak? The moment I brought back the alien forces, they were all consumed by fear!

The whole world trembled!

Do you regret it now? It's too late!

……

Huh? So there are so many other worlds?

What is that? Orcs?

What is that? Zombies?

And what is this? Is it really that outrageous?
