Noah could move his attention on the battlefield now that the two platoons were trapped inside his techniques. Killing those privileged cultivators would help his side, but he wanted to see if he could do more than just that.
His eyes inevitably went on the six leaders among Heaven and Earth's army, but he felt forced to exclude some of them right away, especially Caesar. The latter wasn't a problem for now.
The old man couldn't be a potential target either. Sword Saint was having a hard time dealing with him, but Noah didn't believe that his companion could lose.
Divine Architect was also out of reach. It was probably better to kill her right away, but Noah couldn't butt in when King Elbas was handling her. He had to leave that fight to his companion to allow him to improve.
