A Trial of T4 Structure

I am neither a demon nor an angel, I am neither good nor evil. Yes and no, no and no. I only know that I am T4, I only know that we are all T4, and we are all loyal to T4. Not in the world, not in the world, not seeking the world, not seeking the world. You can call us T4, you can also call us demons or gods. We are nameless and do not seek fame. Looking up is the sky, looking down is the abyss, looking back, there is a sea of ​​flowers everywhere, and ahead is death. I don't want to look back, I am willing to move forward and die, both are T4. ——The update time is uncertain, and it is not certain whether it will be completed. After all, I'm really too lazy. Too tired.
