[Zong Ying Mei] Laughed Wildly and Said He Is My Brother

[The main text is completed, the extra chapter is being updated] My brother has been taking care of me since I lost my memory. Even if the laughter of clown-type creatures kept ringing in my ears, he would never leave me. So I listen to him very much. He asked me to go to Arkham for treatment, and I went. He told me to have some fun, and I did. He told me to gain the Bat's trust and backstab him, and I... Something seems amiss? But for him, I did it anyway. I found the Dark Knight, worked hard to gain his trust, and was determined to betray him at the critical moment and fall into the arms of my brother. I always thought that my brother was Gotham's biggest villain, the Dark Knight's eternal enemy, the peer of the Joker... Until that day, my brother smiled and said to me: "Dear sister, actually they usually call me the Laughing Bat." I finally found out that he had been cheating me: "..." So I am the biggest clown in Gotham? ! In order to prevent me from becoming the biggest clown in Gotham, I decided to take revenge on my brother—— The way he taught me :-D I will take advantage of his trust, betray him at the critical moment into the arms of the bat, and then ask him: "Why don't you smile, brother?"

[The copy of "[Comprehensive British and American] After Becoming Damian's Mentor" is as follows:] Damian Ogo's mentorship is a high-risk profession. Because the League of Assassins asked him to kill his mentor on graduation day. This means that you are not only criticized by students in class, but also monitored by students on a daily basis, and you are also assassinated by students after teaching is completed... You didn't become Damian's mentor by choice. When you came over, the man who was supposed to be his mentor died in front of you. The devil's son who came to apprentice found you. You explain: "I just passed by..." The knife in the hand of the young man with black hair and green eyes was still stained with blood. He raised the knife, "Since he is an irrelevant person, then——" "To be honest, I am your apprentice's disciple, haha. The kung fu you master is far superior to him. If you want to become your apprentice, I will be happy to teach you. Anyway, don't be impulsive, little brother, ah, I mean big brother!" The above lies come from you who do not want to travel to a different world where you will die on the same day. All in all, you survived and became his mentor. "The sound of your thinking disturbed me." The traitor standing in front of you spoke, dissatisfied that your thoughts were wandering in front of him. You can probably guess what he is thinking. He wants to quickly learn skills from you, and then kill you with a knife to find the next mentor... So on the day he was assigned to carry out his graduation mission, you simply escaped. In the end, he didn't attack you or let go of your hand. ... It seems like something is wrong? Intention: Believe in justice.
