Save the World but Be Tall

Lin Yelan is an ordinary tall man who fears society. He has the classic long bangs that cover his eyes, lowers his head when walking, stutters when he talks, and looks like a mushroom when he squats in a corner. Like a quiet shadow walking on campus, not attracting anyone's attention.

"You will be beheaded here." Special Talent Team:...? The next second, the sharp sword was unsheathed, reflecting a bright white light in the moonlight. The blood burst out.
