Qin Zhenzhen wasn't surprised at all. She was well aware that Su Bin had been suspicious of her, especially considering that she had specially modified the Immortal Pill. She also had a hunch that he might have detected something unusual in his food.
Su Bin himself had become aware of the subtle changes in his body. He had initially believed he was ill-suited for martial arts, yet in just one year of training, he had surpassed those who had trained for three years or more. This transformation wasn't due to his diligence but rather a profound change in his body.
What was once the physique of a frail scholar, unsuitable for martial arts, had now evolved into that of a martial arts prodigy. Besides learning from his two secret guards, he had also received guidance from Qin Zhenzhen. After a year, he could hold his own against his secret guards in combat, and facing ordinary adversaries posed no challenge. Running away was the last thing on his mind.
