My Junior Brother Has a Big Problem

After traveling through time and space to a senior brother who was a villain, Lu Sheng originally thought of being more decisive and cowardly, showing off to the protagonist's junior brother, and then slowly and peacefully practicing. But I accidentally used too much force. Then this junior brother seemed to be a little abnormal... "Brother, I just caught a magical beast cub and gave it to you." "Senior brother, I just obtained the ancient inheritance. Please help me take a look." "Senior brother, I just made a furnace of Daluo Jindan. Who else would it be better to give it to besides you?" Wait, why do I feel like I'm more dangerous than the villain now? [This work is also known as "The protagonist's junior brother is my licking dog" and "I am surrounded by licking dogs"]
