As a mid-tier Transcendent.
He had the ability to fly, in addition to the skill to envelop thoughts.
And because he was mid-tier, this ability hadn't been perfected.
He could barely "monitor" a circle.
He couldn't use "consciousness" to observe every single person's actions within the city.
But simply confirming who was leaving or entering the city was still a piece of cake for him.
Therefore, the moment the family of four left Hecheng, he sensed something and immediately plummeted from a kilometer high in the air, hovering behind Chen Yu and his family.
As Chen Yu turned around.
The Transcendent servant activated his power, his voice cold, "Those who leave the city, die."
Chen, in shock and panic, quickly pushed her unconscious father behind Chen Yu, shivering violently. She had the faint feeling that her incisors were going to grow again...
"My lord."
