Entering Gantz

"That's right. That's the fishy part."

Chen Chen nodded. "According to the plot of the original comics, humanity had defeated the aliens. This is pretty far fetched. After all, humans have manufactured spacecraft, yet their weapons are still stuck at the level of conventional firearms and cold weapons… Even putting that aside, I prefer the aliens who have weapons of mass destruction as a trump card. Even if they can't destroy Earth, it'll be a piece of cake to destroy humans.

"But now, it seems that human civilization has not gone extinct because of war. In other words, either the aliens used some superior method or something else destroyed the human race."

"So, do we still head to Gantz's dimension to search for more advanced technology?"

Little X said, "I'm worried that their technology was annihilated along with human civilization."

"Nah, that's good news for me."
