If I know the stories of Ni Kuang's Blue Blood Man and Return to Tragedy, please help me! Help! Twenty minutes!

Blue Blood Man is one of Ni Kuang's famous science fiction Wesley series, in which aliens appeared for the first time. Because the whole story is particularly long, it is divided into two volumes, the first and the second. The second half of the story is called "Return to Tragedy". The original book said that the blue-blooded man came from Saturn, but in Wesley's memoirs, Wesley decided to improve all his mistakes, so the real source of the blue-blooded man was Titan. When they are nervous, happy and sad, their faces will turn blue, just like people on earth will blush. Note: there are plots, endings or other related contents below, which may reduce the interest in enjoying the original work. Wesley's college classmate Tian Fang is of noble descent. Anyone who sees this secret will involuntarily have suicidal thoughts, even Wesley is no exception. Fortunately, I survived when I was discovered by my classmates at a critical moment, and I didn't know what to do from then on. Until many years later, in a ski resort in Japan, Yoshiko Kusoda slipped when she saw that Tanaka was bleeding with blue blood, and then she killed herself and was rescued. The situation is the same as that of that year. In pursuit of the truth, Wesley was hit hard by radiation from Tian Fang. It turns out that Tian Fang is an alien from Saturn. Although his appearance is no different from that of the earthlings, his aristocratic lineage and high scientific wisdom are the biggest differences between him and the earthlings. Tian Fang was trapped on the earth because his spaceship was hit by a meteorite, but another companion fell from the sky to a fishing village in Japan. Fishermen mistakenly thought he was the moon god, and later set up the largest organization in Japan, the Moon God Society, and gave the solar system flight director around him to Inoue's family, hoping to return this instrument to Tian Fang and return to his hometown Saturn one day. This instrument has become the target of competition between Luna and the Soviet Union, and it must be obtained in order to return to Saturn. This story has also been adapted into a radio play and a film. Return to Tragedy is one of Ni Kuang's famous science fiction Wesley series, and it is the sequel of Blue Blood Man. According to the author's preface, the name of the next episode means that "Blue Blood Man" Tian Fang tried his best to return to Saturn, but he didn't know that his planet had suffered a tragedy. Note: there are plots, endings or other related contents below, which may reduce the interest in enjoying the original work. With Wesley's help, Saturn, who lives on the earth, was able to retrieve the flight navigator. However, the invisible flying demon that has been threatening Saturn's people has also been mixed into the earth. Although he finally succeeded in boarding the rocket, he also sacrificed Wesley's close friend Nelson and was invaded by the "cannonball to the poison room". When Tanaka set foot on his way home, Wesley learned from the information sent by Tanaka through the cosmic communicator that his hometown Saturn had completely changed. Because of the development of weapons between countries, the human form of Saturn has been turned upside down, and the brain tissue has been seriously damaged into * * *, and some have become like octopus. At the same time, the communication with Tanaka was interrupted by the exhaustion of power supply, and the news of Tanaka's going here could no longer be known.
