Two Worlds: Building Immortality by Reselling Medicine

Modern aluminum electrolysis technology makes silver worthless. In ancient times, without this technology, silver could only be extracted from silver mines. Going back to ancient times to earn silver is incredibly foolish... Even exchanging it for gold would be much simpler, wouldn't it? A tenfold increase in value!

Silver can be exchanged for gold or jade! What is silver worth in modern terms?

This protagonist is being chased like a dog for some ridiculous medicine prescription. He has no power or influence after over a hundred chapters. He should either be building his own power, unifying the world, collecting various martial arts techniques, etc. What use is ancient money to him? If you want to unify the world, go dig for gold and silver yourself. This whole thing feels so petty.

After reading the first dozen or so chapters, I think the author is truly talented. As modern people, we've wasted our time learning mathematics. In ancient times, the ratio of silver to gold was probably less than 1:100, more like 1:10, while in modern times it is more than 100 times.

He's truly run out of ideas. It abruptly shifts from a martial arts world to a cultivation world with secret realms after only 140 chapters. We've begun the endless, nested dungeon crawling. Even the level of a small town can be written poorly.

The Li and Lu families have tried to kill the protagonist time and time again, and he's always let them go so easily? And he's even thinking of cooperating with them? Who would cooperate with a coward like that? Wouldn't it be far more profitable to just rob them?

The biggest fear when writing a book about two worlds is that the author's knowledge, life experience, and social experience are inferior to the reader's, which naturally leads to more flaws.

The plot is drawn out and not satisfying at all; there's absolutely no research on modern medicines and weapons; and the ancient world feels completely unsafe. It's like they just started writing on a whim.

There are too many flaws; it's unwatchable. Can you even call it cooperation if you're working with someone of unequal strength? You're just a gold digger. And joining someone else's family, living right next door under their noses—how do you explain the source of your resources? Besides, your resources are all incredibly valuable. I don't believe that in a lawless, high-martial-the-world ancient world, anyone could resist the temptation of such immense wealth and not mess with you.

The protagonist is too naive and innocent. Did the protagonist actually experience the ancient environment? Did they study history or watch movies? And stop using Desert Eagle so often. It's just so-so.
