In fact, when Project X was gathering his clones and his powers were raging, Zhao Yao had prepared a Spicy Cat Strip. He wanted to wait for Time Freeze to cool down and use the enhanced Time Freeze with Ultra Rapid Regeneration to run over and stuff a Spicy Cat Strip into his mouth.
Sleep Medusa was Zhao Yao's first trump card. He had planned to use it after Project X gathered his clones.
If the plan failed, it would be a disguise.
The Spicy Cat Strip was the real trump card.
No matter how much he overpowered him, no matter what Project X did, before Project X had gathered all his clones, he did not use the Spicy Cat Strips.
He knew that he only had one chance, if couldn't get rid of him once and for all, the Spicy Strips would be useless.
However, the sudden appearance of Mango spoiled the chance. Zhao Yao watched Project X take Mango's powers and intelligence but he could not stop Project X.
