Yinzhen's excitement subsided somewhat by evening. Having spent so much time with Yunrong, Xinzhen instinctively sensed that something was wrong with her, as if she was worried about something.

Yinzhen was puzzled. The successful trial run of the steam train was a cause for celebration, and he couldn't understand why Yunrong was so downcast.

Yinzhen suppressed his good mood and asked Yunrong, "What's wrong? You don't seem very happy."

Yunrong hadn't expected Yinzhen to be so sensitive; she had only been a little worried, yet Yinzhen had already noticed it.

Yunrong knew that steam trains were inevitable, but she still had to say what needed to be said. In her previous life, Britain, as the country of the First Industrial Revolution, enjoyed the fruits of the Industrial Revolution, but they also endured a century of harmful environmental damage.

They developed too fast, disrupting the harmony between humanity and nature, and they too have received punishment from nature.

Yunrong: "This should have been said earlier. Although steam technology is convenient and greatly improves production, especially in terms of communication, it also brings people closer together. However, everything has multiple sides. Although it is good, it is not without its harms."

Yinzhen frowned. He couldn't think of any potential harm. After all, he had only seen the result of the country becoming rich and powerful after the application of steam technology. As for harm? He really didn't know.

Xinzhen: "What harm?"

Yunrong: "Nowadays, the power source required for steam technology mostly comes from fire, and a large amount of coal is being mined. Coal is not an inexhaustible energy source, which will cause a shortage of coal resources in our area. On the other hand, burning a large amount of coal is also a problem in terms of environmental pollution."

Yinzhen understood that Yunrong's focus was on environmental pollution: "I understand what you mean by the shortage of coal resources, but what do you mean by environmental pollution?"

Yunrong didn't know how to explain it either, so she only told Xinzhen about the dangers of environmental pollution: "When a lot of coal is burned, gases that can warm the air will be produced. If the combustion is incomplete, toxic gases will also be produced, and there will even be some fine particles that can be inhaled by the human body. Moreover, once steam technology is put into use, industry will inevitably develop rapidly, which will only produce more toxic and harmful substances. They may not seem obvious, but the adverse effects are indeed numerous."

Yinzhen was someone who listened to advice, but the promotion of steam technology was indeed imperative, although how to plan it required further consideration.

Yinzhen: "You've thought this through very well. I was so eager to get results that I made a lot of assumptions. With you by my side giving me pointers, I'm spared from making any bad decisions."

Yinzhen was truly grateful to Yunrong. Without her, although he could have developed the Qing Dynasty, he would not have been able to avoid those hidden dangers.

Yunrong: "If I hadn't met you, it would have been fine. I just did what I was supposed to do and did things that I could be proud of."

Yunrong was unaware that, because of her reminder, the development of the Qing Dynasty was quite different from that of Western society. Although there were some inconveniences in the early stages of development, and some merchants even privately criticized the emperor for creating so many unnecessary regulations for profit.

However, in later generations, the Qing Dynasty changed its name to Huaxia. Although the Qing imperial family became a figurehead with little real power, the far-sighted policies of Emperor Kangxi were still admired, which is why the imperial family was able to survive.

Yinzhen: "The steam technology is not mature enough at present, and the laws to circumvent it have not been formulated. I will not allow the steam technology to be used in practice."

Yunrong looked at Yinzhen and her expression relaxed.

To be honest, Yunrong hadn't expected Yinzhen to go to such lengths. Yunrong also knew about Yinzhen's inner struggles. Frankly, Yunrong couldn't guarantee that if she witnessed the tragedy of national subjugation and saw her own people, who shared the same blood, being enslaved, she wouldn't be able to maintain the same patience as Yinzhen.

After all, the sooner the feud between family and country is resolved, the better.
