Although he said that, Ye Xiong had no confidence at all in his heart.
With the Third-Generation Gene Warrior's transformation, he was already struggling to cope. The Green-Eyed Monster in front of him was very likely a Second-Generation Warrior. If it transformed, Ye Xiong truly had no confidence at all.
Unless Ye Xiong also transformed himself.
The problem was, although Ye Xiong guessed he was also a Gene Warrior, and even a more advanced First-Generation one, he had no idea if he could transform, or what side effects a transformation might bring.
Ultimately the Green-Eyed Monster did not insert the syringe into Ye Xiong but put it away instead.
"You seemed so eager to get rid of us, what's the matter? Are you afraid of the side effects after transforming or, perhaps, you have a time limit on your transformation? You can't be sure whether you can kill me within the time of the transformation, can you?" Ye Xiong sneered coldly.
