In the second meeting with Hyacinth, Zhang Heng learned what the Balance Blade thought of him. Even if he took the initiative to warn Hyacinth that Altrus, who would be appearing next to Commodus tomorrow, was a fake, Hyacinth would be still unwilling to disclose more information about their next plan. She had made it clear that she did not fully trust Zhang Heng.
And there was nothing Zhang Heng could do about it. This was probably the negative impact of his disbelief in Kreis. It had caused the Balance Blade to doubt which side he was on in the upcoming war. Considering that he mingled with Commodus now, whether he was willing to abandon everything to join the Balance Blade to help them to maintain the balance was also a question worth discussing. And the Balance Blade clearly wasn't willing to bet on Zhang Heng's loyalty at this critical time.
