Exchange Marriage? Not a Puppet? Don't Even Think About Taking Back What You Gave Me!

An alternative to "marriage exchange"? Talk about cheating after marriage or domestic violence within marriage, just talk to my worm! After Cheng Shian finally got out of the army, he originally thought about showing off his skills with his baby Gu, but was reminded by his "dear master" with a guilty look on his face, "Now is the modern society. If you are infected with parasites, you will go to the hospital to attend the Gastroenterology Department, Infectious Disease Department, etc., And then take medicine, injections, and surgery..." Huh? No? Forget it doesn't include distribution. Why didn't you remind me of this before? ! Angry and angry, Cheng Shian woke up and arrived in the "future". It is almost the same as the Western magical world in the novel. There are dragons, elves, orcs, dwarves, etc. Here. The Sacred Heart City where Cheng Shian is located is the capital of the Shengyao Kingdom. It is said to be the capital of a country. In Cheng Shian's eyes, it is not as big as their city in his previous life. Those who take the name of Holy belong to the Holy See. Similarly, those who take the name of Dark belong to the Dark Church. The two major religious forces of the God of Light and the God of Darkness divide the human camp. Cheng Shian has no affinity with the light element and has been considered an ordinary person. He is also ready to travel the world as an adult. Who knows the "engagement" between the two great forces descended from heaven. The Dragon Clan and the Elf Clan are designated to seek the son of his family. Oh, yes, he can barely be considered a prince. Although he is not so favored and not so famous, he is the only two princes in Shengyao Kingdom. Did the arranged marriage fall on me? Cheng Shian remembered it later. ​Wait, that's not right! I have Gu insects and can control them. This is... The puppet assigned to me! Take care of the work, here I come! Intention: There is plenty of strength and means!
