What are the illogical plots in The Legend of the Condor Heroes?

I remembered that in The Legend of the Condor Heroes, Huang took his wife Feng to cheat the old urchin's nine spirits. This plot is modeled after the plot in Romance of the Three Kingdoms in which Zhang Song tricked Cao Cao into tearing up Meng De's new book. Mrs. Huang and Zhang Song both recited the original works in a short time, and then after testing each other, the original owners were furious and tore up the original works.

But the difference is that in The Romance of The Three Kingdoms, Zhang Song only said that The New Book of Meng De was widely circulated in Shu, which did not change the essence of the book (or The Art of War), so Cao Cao just thought that his painstaking efforts coincided with those of his predecessors. However, Mrs Huang lied to the old urchin that the second volume of Jiuyin Zhen Jing, which recorded various martial arts moves, was an astrology book. The old urchin looked at the book and said, "The books are all about the practice methods and secrets of various martial arts."

The ages of Huang Rong and Guo Jing. Huang Rong has always called Guo Jingjing's brother, and the decimal number should be that Guo Jingjing is bigger than Huang Rong by default. However, when Guo Jing was born, Qu Lingfeng was kicked out of the house by Huang in Peach Blossom Island, and Huang also kicked several disciples out of school because of the sadness of his wife's death during childbirth. Thus, Huang Rong should be bigger than Guo Jing.

If there is anything wrong with the logic of the story, I think the first thing is that some things in the story happened at a different time from the real time in history, such as Temujin's entry into the customs and Guo Jing Huang Rong's stationing in Xiangyang City. Secondly, in the new edition of With the Boss, the description about how Mu Nianci gave birth to Yang Guo is not accurate. In some versions, Mu Nianci was arranged to jump off a cliff, but Mu Nianci was injured on such a high cliff. How can he survive after jumping off the cliff? Even if it can survive, even the baby in the belly can be born safely, which is a bit unreasonable.
