I Was in Douluo as a System, and Tang San Was Ruined by Me.

Chen Qingqiu traveled through the Douluo Continent and neither became a god nor a titled Douluo. Instead, he became the "weird weapon system" in Tang San's body! As long as the host is given weapons with [causal side effects], it can continue to cause trouble and become stronger. [Xuanzhong Ruler]: Hit the enemy, and the opponent will be forced to laugh "Jie Jie Jie"; the host must look up to the sky and roar "Thirty years to the east of the river, thirty years to the west of the river, don't bully the young to be poor!" [100% Chance of being caught with bare hands]: A sword strikes down, regardless of level, all the gods and Buddhas in the sky have to kneel on their knees and clasp their hands to catch the sword! [Square Dance Aunt's Speaker]: Pick up the speaker, no one can beat me in my BGM! [Dad's Dried Fugu]: Get away from the monsters and use magic to defeat the soul! At the Continental Advanced Soul Master Academy Elite Competition, Tang San took the photo with a ruler, and the Wuhundian team laughed wildly: "Jie Jie Jie!" Tang San raised his ruler with tears in his eyes and shouted in shame: "Don't bully a young man into poverty!" The entire audience was stunned, and Douluo's style of painting began to completely collapse. As the system was upgraded, Chen Qingqiu began to bind more hosts... Tang Hao: "Martial Soul Palace! Listen to this song "The Most Dazzling National Style"!" (Carrying a large speaker on his shoulder, smashing the Pope's Palace with a hammer) Ning Rongrong: "Grandpa Sword, Grandpa Bone, take the sword!" (Li Tianwang is possessed, and the two titled Douluo are forced to kneel down to catch the sword) Qian Renxue: "The key that hides the power of angels, transform!" (The magical girl form shocked Qian Daoliu for a whole year) A crusade by the Council of Gods? Chen Qingqiu fired a bunch of causality weapons with his backhand, including Shura God and Poseidon God, all within the set rules!
