In Yu-Gi-Oh, but Mechanical Ascension (1-148).

Summary

You Feng performs a series of powerful XYZ summons, starting with "Shining No.39 Hope Emperor Hop" and using a Level Up Magic card to overlay it with "Chaos No.102 Light Fallen Angel - Gui Mo," which has 5 XYZ materials. He then summons "Chaos XYZ - Ji Wang Huang - Alien Crystal Being," a Rank 7 monster with an attack power that increases based on the number of XYZ materials it has. You Feng reveals that this monster can copy the effects of a "No." monster from his graveyard, specifically "No.86 Ying Hao Guan Jun - Gun King," allowing it to gain powerful effects including immunity and lockdown against summons. The president, Kaiba Seto, recognizes the challenge he faces but vows to find a way to counter You Feng's overwhelming power, despite his lack of cards. The crowd is captivated by the duel's intensity and You Feng's strategic prowess.
