Summary

Katsuya Jonouchi and You Feng witness a chaotic battle, prompting Katsuya to want to intervene. However, You Feng insists on handling it himself and mistakenly attacks the brown-skinned boy, Ma Li Ke, whom they initially believed to be a victim. You Feng reveals that Ma Li Ke is the mastermind behind the Gurus Group, leading to a confrontation. Ma Li Ke, furious from the attack, orders his men to kill You Feng, but a burly man named Li Xi De intervenes, challenging You Feng to a duel. You Feng accepts, and they prepare for battle.

Katsuya and Kaiba Seto observe the duel, with Kaiba expressing concern over You Feng's strategy being hindered by Li Xi De's card. The chapter ends with Li Xi De summoning a monster, escalating the duel.
