Dean Sima scoffed at that. "Old Du, stop letting your imagination run wild. Leaving aside the fact that it's only a legend, there are plenty of holes in the story. Just think about it—how could there be immortals in this world?"
Du Yile retorted, "If there are no immortals, then given the technology of the Qin Dynasty, how could they have forged such a miraculous sword?"
Dean Sima said, "What's so strange about that? That period wasn't far removed from the Spring and Autumn and Warring States periods, when a hundred schools of thought contended. Some technologies that seem inconceivable to us now hadn't completely disappeared yet. It was perfectly normal for them to forge such a sharp weapon. As for why it seems inconceivable to us now, that's because modern technology hasn't advanced to that level yet. Once technology develops further in a few years, the mystery will naturally be solved."
Du Yile shook his head with a laugh. "Anyway, I find it pretty incredible that modern technology still hasn't reached the level of more than two thousand years ago."
Yu Renpeng also sided with Dean Sima and said, "You can't put it that way. If technology back then was really so advanced, why couldn't they make some of the machines and equipment we have today? At the end of the day, those were merely rare exceptions."
Chu Chen chuckled. "There's no point arguing about it. It happened thousands of years ago, and we can't go back in time. Who knows what really happened back then? I think aliens may have visited our planet and brought the technology with them."
Hearing that, everyone laughed as well. As Chu Chen had said, there was nothing wrong with researching things from the past, but trying to get to the bottom of
