A little spoiler exists. Chinese here. In my opinion, this is one of the best novels ever. I saw some reviews complaining about that the novel is so boring and decided to give up. Well I have read more than 1700 chapters and I agree that so far it is literally boring, no doubt. But don't give up and stick to it please because actually the exciting part has not come and later the first excitement will come in chapter 230+. It's a story about a civilization which is suffering from the lack of energy and matter. That's not because of they wasted too much of them but due to their bad luck. Their planet is the only planet on their solar system and their solar system is the only one around hundreds of light years. You'll be shocked by how the civilizations tried to struggle, survive the frustration and how they finally got saved or elimated. This will also make you think about ourselves, the human race. Y'zaks in the novel once said, "I just can't understand you human. You have a perfectly beautiful solar system and rich matter and energy around you. You'll have much more opportunities than the unlucky ones. But you humankind don't unite together and even war for all kinds of boring reasons. That's not good. Why don't you keep peaceful and study the space and universe? You'd be one of the strongest civilizations in this universe. "We should think about this.
