As Zhang Cheng ordered Swampert to attack, Li Han also commanded Delphox to counterattack.
Since Swampert was a Water-type Pokémon, Fire-type moves would not be very effective against it, so Li Han chose to have Delphox use its signature Psychic-type move.
Delphox focused and rapidly gathered a large amount of Psychic-type energy. The energy converged into a Psybeam that shot toward Swampert.
Both Pokémon used ranged attacks. Water Pulse and Psybeam launched simultaneously, each striking the opposing Pokémon.
Swampert reeled from Psybeam, its head spinning. The attack dealt heavy mental damage, reducing its HP by two-fifths.
Delphox was also hit by Water Pulse. Struck by the Water-type move, it cried out in pain as its entire body was sent flying.
However, Delphox was not defeated outright. It had originally had one-third of its HP left, and after taking Water Pulse, it was left with less than one-tenth.
"Swampert, use Mud Shot!"
Seeing that Delphox could still fight, Zhang Cheng did not hesitate. He immediately ordered Swampert to finish it off as quickly as possible before anything else could go wrong.
"Gana~ Gana~"
Upon receiving the command, Swampert began absorbing the abundant energy of its own type from the ground. Under its control, the dense Ground-type energy formed clumps of mud.
Once the mud had taken shape, Swampert slammed the ground, sending the clumps formed from Ground-type energy hurtling toward Delphox.
Although the badly wounded Delphox had not yet fainted, it was barely hanging on and could offer no resistance. When Mud Shot struck, it immediately lost the ability to battle.
"Delphox, come back and rest." Li Han took out a Poké Ball and recalled the defeated Delphox, then sent out Medicham, her last remaining Pokémon.
"Medicham, you're up!"
Zhang Cheng and Li Han now each had only one Pokémon left.
