The vast amount of Dragon-type energy Kingdra had absorbed mixed with the energy inside its body, becoming extremely volatile.
Kingdra had experience dealing with this situation. It used its own power to forcibly suppress the restless energy, then compressed the Dragon-type energy inside its body and released it in a powerful attack.
Deep yellow Outrage energy erupted from Kingdra's mouth and swiftly struck Slaking's body.
Outrage proved highly effective, dropping Slaking's HP directly below half when it hit.
"Great job, Kingdra! Seize the chance and use Outrage again!"
The effectiveness of Kingdra's Outrage came as a pleasant surprise to Zhang Cheng. Having witnessed its power, he continued directing Kingdra to attack, hoping to gain an even greater advantage.
Following Zhang Cheng's instructions, Kingdra continued expelling the restless Dragon-type energy inside its body.
However, Kingdra was in terrible condition, and that volatile Dragon-type energy was not easy to control.
The Outrage energy broke free of Kingdra's control and shot wildly in every direction, leaving it unable to hit Slaking at all.
"Here's our chance! Slaking, use Feint Attack!"
Seeing Kingdra's attack fail, Du Ling immediately ordered the newly rested Slaking to attack. As long as he could defeat Kingdra quickly, he still had a chance to turn the battle around.
Once rested, Slaking was quite willing to cooperate with its Trainer. Upon receiving Du Ling's command, it swiftly gathered Dark-type energy and unleashed Feint Attack.
Feint Attack was more effective against an unprepared opponent, and Kingdra was completely unprepared at that moment.
The runaway energy already had Kingdra overwhelmed, leaving it no time to deal with Slaking's attack.
Slaking's massive body appeared behind Kingdra. Dark-type energy burst from its hand as it delivered a powerful blow.
After Slaking's attack struck Kingdra, the uncontrolled energy inside Kingdra began to backlash as well.
