Chemical Engineering in the Tang Dynasty

One month and 11 days have passed since the protagonist traveled to the present time. He went to Chang'an three times, moved twice, went to the county three times, and five small towns. He made soap, alcohol, glass, got a girl and got engaged, opened a shop, caught thieves, killed people... Bought cows and horses, and found many people to do things without spending any money.

I urge all my fellow readers not to try this poison.

This protagonist is the stingiest person I've ever seen: he doesn't pay for things, he doesn't pay for things made, he doesn't pay for bodyguards—I can tolerate all of that, but he can't stand it when people have to kneel and beg for money! What's the author's mentality? Is this even interesting?

I couldn't stand listening to the audiobook anymore, I had to rant. The average farmer in the Tang Dynasty lived better than the average farmer in modern China in the 1990s; they only ate meat once every ten days—impressive! Another merchant offers you good tea but serves you ordinary tea, and you, an ordinary farmer, think ordinary tea isn't good enough for you? You're too magnanimous!

I've been reading for over ten years, and I've read countless novels, but I've never seen one this long-winded. For example, when you're negotiating with a merchant, if you're not going to talk about the bag's design, why explain so much? And what about the marketing ideas? Are we ancient people? Are we ancient people? Why explain all this stuff? The whole thing is just a long, drawn-out mess with neither side saying a word. 😡

This protagonist is so stingy!!! He refuses to pay for anything that's clearly a bargain, yet he expects people to kneel and give him horses, insists on paying rent to rent a place, and even gets begged to buy from unfamiliar wineries—it's all so inexplicable! Making porcelain bottles is free too... He just wants to take advantage of every little thing!!! Is the author having a fit of petty miserliness?

I can't continue reading this book. Its values ​​are warped. It challenges even filial piety in the Tang Dynasty and tries to view ancient human relationships with modern concepts. You're really something.

Various popular science articles. 25% Of each chapter is the main text, and 75% is various popular science articles. Extremely long-winded. Things that other authors can gloss over in a few sentences are dragged out in this book. Various ramblings. Apart from the 75% of copied and pasted popular science articles, the rest is just whatever comes to mind, without regard to whether it was relevant to the context.

The author lacks basic scientific knowledge and literacy. Liberal arts students shouldn't write things that are beyond their comprehension.

Why do I keep finding that the author always writes that the emperor of the Tang Dynasty must be Li Er (Li Shimin)?
