One could not simply assume that Troubled Times was a novel created by Dong Zhuo. In many novels set in the Three Kingdoms, the chaotic times at the end of the Eastern Han Dynasty were the result of many complicated factors. From the perspective of political structure, before Dong Zhuo, there were already power disputes between the royal family, relatives, eunuchs, party members, aristocratic families, and soldiers in the Eastern Han Dynasty. The struggle and strife between these forces caused the internal contradictions of the Eastern Han regime and the foundation of the rule was shaken. For example, during the reign of Emperor Huan, there had been serious political corruption and social unrest. From a social perspective, land annexation was serious, and the gap between the rich and the poor was huge. A large number of farmers lost their land and became refugees, which buried hidden dangers for the formation of troubled times. Dong Zhuo's appearance and actions had indeed pushed and intensified the chaotic times. He deposed the emperor, connived at the soldiers burning, killing, and looting in Luoyang, and had a fierce confrontation with the vassals, further disrupting the already precarious political situation and plunging the Eastern Han Dynasty into deeper chaos. However, he was more like the last straw that broke the camel's back than the sole creator of the chaotic world. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

I recommend Planet Escape. This book is super cool! The author loved to play Fight the Landlord, and he was still a high school student when he wrote this sci-fi novel. The story was about the Earth's deviation from its orbit, the outbreak of all kinds of disasters, the human race moving towards the era of black technology evolution, and then building a spaceship to escape. The protagonist Xiang Gan was reborn before the disaster and wanted to lead Earth to roam the sea of stars. This book had a big imagination. It combined the apocalypse and space escape into a super interesting story. It was like playing StarCraft with Earth. The beginning was well written. Although the end was a little broken and the ending was rushed, the flaws did not obscure the merits. There was a lot of sci-fi knowledge in the book, and it was easy to understand. Compared to " The Three-Body Problem," it was easier to understand and more interesting. There were also many unique settings, such as the evolution of human civilization and the collision with alien civilizations. The overall sense of immersion was strong. It was very cool in doomsday novels. Those who liked science fiction should not miss it. Forget about Earth No. 7 Guide, it was a ten-thousand-year-old pit.
