The Era of the Myriad Heavens

Author, the world-building and power system of your book are very similar to those of the Age of Exploration. You could refer to their settings if you like, and learn from their strengths. Like your story about how after Earth collapsed, a spacetime tower appeared, and the universe itself was as vast as it is. There should be other places like that too, right?

Recognizing Whitebeard as one's father??? While he was good to his children, it's not enough to just recognize him as one's father upon meeting him. Although many viewers of One Piece recognize Whitebeard as their father, that's a difference in perspective. As a Chinese person, do you know how significant the meaning of recognizing someone as one's father is?

What's going on with this dimensional invasion of the world?

Ten thousand years later, when humans are able to invade other worlds, why do they seem to be in a worse situation than they are now, with even food being a scarce resource?

This currency system: one copper coin buys ten buns, one time-space coin buys one million copper coins, one time-space coin buys ten million buns, and one goblin buys one time-space coin. The entire family's income can't even afford food for a first-tier protagonist. Wow, that's incredibly stingy! Is this family really that bad?

This book is a mess! A single animal hide is only worth a few hundred or a few thousand copper coins when recycled. You spend dozens of time-space points to bring back one hide, and then you claim one time-space point can be exchanged for a million copper coins. What idiot would do that? What were you thinking, author?

There are too many flaws, the data is simply incomprehensible. The protagonist kills a wild boar for 30 time-space points, worth 30 million copper coins, then slowly collects and sorts the materials from the boar, bringing them back to exchange for a few dozen copper coins. This feels like someone who can earn tens of millions in less than a day still has to scavenge scraps to earn a few dozen coins to supplement their household income.

The name is wrong. It's not "Descending into the Celestial Era," it's "Descending into the Japanese Era." I don't watch Japanese anime... Okay, I'll be honest, I don't understand it.

This book feels like a mere chronicle of events, not a novel! All the characters are emotionless robots.

The author's failure to focus on the joy of the gains is a major mistake. The gains from each battle are vaguely mentioned, even though they are highlights that are overlooked. This is a major flaw.
