I Am the Villain: Stealing the Fate of the Protagonist's Younger Brother

Lin Tianhao traveled through time and became the eldest son of the Lin family, but he did not expect that his younger brother was the legendary chosen one. There is also an unreliable system around him: "What? All the protagonist's friends are going to lose their registered permanent residence?" "The main character who just started is the Holy Body of Chaos. Can I plunder it?" "How could I, a decent gentleman, do such a disgraceful thing!... My stupid Ou Doudou, my brother is doing this for your own good!" "Brother, you can't jump off this cliff. Let me bear the pain for you." Lin Tianhao came to the cave on the cliff and got a shocking secret. As long as you take your silly brother with you, you can encounter adventures in the cave, and when you encounter an opportunity, you can pretend to sacrifice yourself to protect your brother to gain a wave of favor. Lin Tianhao: System, that girl of destiny who seems to be the protagonist is not good for me, right? System: There is so much nonsense, just do it if you are asked to do it. If you don't do it, the system will just commit suicide. It's up to you. Lin Tianhao: Well, in that case, I will fight for the system this time. This novel and its characters are purely fictitious.
