Traveling Through Douluo, Tang San Became the Second-In-Command for a Thousand Years?

Good news: I traveled through Douluo and was bound to the Heaven-defying Golden Finger! Bad news: My golden finger is specially designed to steal the protagonist's tricks! This system is so unbelievable that I don't have to work hard at all. As long as I "get along well" with Tang San, what's his will be mine. Tang San: "Lin Feng, we are brothers!" Me: "Yes, brother, can you lend me your Purple Demon Eyes?" (Inner os: You have to borrow it even if you don't want to) Result: His purple demon pupil disappeared, and I gained the "Eye of Insight". Everyone: "Lin Feng is so awesome! What happened to Tang San?" Tang San: "I still have the Tang Sect's secret skill!" Me: "That's just right, I'm missing some hidden weapon skills." (Smile) Result: His Zhuge Divine Crossbow failed, and my fingertips flickered with cold light. Xiao Wu: "Lin Feng, you are much stronger than Tang San!" Tang San: "You can't steal my fundamental technique!" Me: "Oh? Really? The analysis progress is 99%." (Playing) Result: He vomited blood and fell to the ground, his foundation shaken. Master: "Tang San, you are in very bad shape recently." Me: "Tang San, don't be discouraged, we will continue to "discuss" tomorrow! After all, we are brothers."
