Sailing with Luo Chong to Weishan Commandery, Niu Wei's feelings were complicated. Although he had spent only a year in the Han Tribe, everything he had seen during that year frightened him. The Han Tribe had developed far too quickly.

When he had first arrived a year ago, Niu Wei had attended school in Hanyang City. Every day, when he returned home, he could only light a tung-oil lamp for illumination. Back then, he had thought, This thing is so advanced. I wonder where they get all this oil. It definitely isn't animal oil of the kind I've seen before. If they had been in his own tribe, who would be willing to burn animal oil in a lamp? They barely had enough edible oil for people to eat, let alone waste it on lighting. What was more, they had never even imagined that lamps existed. When they needed light at night, they could do no more than light a torch, or simply build a bonfire. But now...

As he watched the beams of light from the towering lighthouse before him sweep constantly across the darkness, Niu Wei felt a deep sense of inferiority and powerlessness. His own oil lamps had not even become widespread, while the Han Tribe had already switched to the more advanced Calcium Carbide Lamps. He did not know how the things were made, either. They merely tossed in some crushed stones, added some cool water, and could use them as lamps—and they were so bright.

The Calcium Carbide Lamp brought more than merely a technological gap. Some things even the natives of the Han Tribe had never thought of, yet Niu Wei had. A single Calcium Carbide Lamp had already given the Han Tribe more time to develop.
