Developing Across Time: It Started with Stealing a Phone from Emperor Renzong of Song

So far it's alright, but Chapter 13 has a major flaw: the "equivalent exchange" tactic. Exchanging rebar and helmets is one thing, but then they inexplicably give away expensive cigarettes, leaving us with a lot of rebar. What's so great about cigarettes? What's the point? Chapter 16 is full of pointless jokes.

The only things that modern times can do to ancient times are advanced productivity, scientific knowledge, and advanced political systems (a clash of ideologies). It's very difficult for a single emperor to change the face of a dynasty, unless they are powerful emperors like Zhu Yuanzhang or Li Shimin with real military power. Otherwise, it's all like water—easily soluble in water.

A feudal dynasty with powerful military force would be a huge disaster for the world and the Chinese people.

This is utterly disgusting... Sending rebar to the Song Dynasty as weapons? Do you think the Song Dynasty were primitive? The claim that the Song Dynasty had the best military in the world is a joke? He was the emperor! The simplest way to help him is with the explosives formula: catapults firing explosives—what city couldn't they take?

Chapter 29: The protagonist refuses to exchange for Old Zhu's muskets, citing the fear of making a spectacle of it? Wouldn't it have been better to exchange with the Song Dynasty or the Shu Han Dynasty? Even later on, wouldn't it have been better if different dynasties could exchange goods, with the protagonist acting as an intermediary or a platform charging fees?

It's a haphazard, incoherent mess. Safety helmets, stainless steel pipes, threaded steel—none of it is practical. A flintlock pistol needs seamless steel pipes; anything else will explode. This stuff isn't regulated; the author, who claims to have worked on construction sites, should know this. As for the other two items, they're even less useful. And are you sure you want to issue paper money? Never mind, I can tell you have ideas. Good luck.

Later on, we could explore establishing a rudimentary industrial system in the ancient world, and then depict the changes that modernity brings to ancient society, including military and political aspects, as well as the lives of ordinary people.

I couldn't stand reading the part about the steel bars for the Song Dynasty. Was this written by an elementary school student? So brainless! Did the Song Dynasty really want a few dozen steel bars? Even a history book of the Song Dynasty would be better than this. What the hell? Do people write books without using their brains these days?

Is things getting better, guys?

It's really a bit difficult for me; my historical knowledge is too limited.
