As a Villain, How Can I Be so Respected?

My name is Bai Xiaozhou. I grew up in the Demon Sect since I was a child. The Demon Sect intends to control the world, and the world will naturally eliminate demons and defend the Tao, so the people of the Demon Sect have become the targets of everyone's shouting and beatings. One day, the Demon Sect issued a mission, and an immortal from the Qingshan Sect ascended to the throne. This sect had great potential in the future, and the Demon Sect wanted to control and annex it, so it arranged for the Demon Sect's spies to infiltrate it. And I am one of them. My body has been unusual since I was a child, and I can absorb other people's attributes through contact. Therefore, everyone in the Demon Sect is wary of me, but they have never succeeded. Until now, I have entered the Qingshan Sect and become an undercover agent. I am not familiar with the place here and I can use my fists! But I didn't know that the person being absorbed would receive rare compensation. So under my troubles, more and more people from the Qingshan Sect came to me and wanted to practice, and they even became famous. Some people came to visit me. I was very confused, why did the Qingshan Sect become more and more powerful despite my efforts? Many years later, I contacted my Demon Sect Master. Master: Can you close the network if you contact me? Bai Xiaozhou was sweating profusely: No, Master, I feel like we can't defeat him.
