Dai Yan: "Old Deng, give me some gold coins. Mr. Raymond is waiting for me outside!" Tololo: "I'm going to the observatory with the old man and won't be back tonight. What? You're going too, so you can get some help." Lightning: "I'll tell you later about how I gave the Raymond pendant to Dai Yan. What's wrong with taking the blame for your best friend? If you keep talking nonsense, it won't be the little thug who'll blow you up next time, Old Deng!" Facing the ultimate insult from Xixizhong, Cheng Chunan was furious. He decided not to pretend anymore! Showdown! I am the only commander of the Azur Lane port area! The agent of the Church on the Ash Front! The captain of the exploration team that tore apart the Mecha God on the Cross Front! Xixizhong, how are you going to face me, the three-line integration! How are you going to face it! Not only Griffin, I want the whole world to see what the commander's wrath is!
