Sinos didn't use the Flashing Technique.
The Flashing Technique couldn't possibly break free from the blockade of the Four-sided Blood Prison.
After all, the Flashing Technique is only a First Tier skill. Normally, the places it can reach are only within the line of sight or within the range of the Spatial Perception skill.
The Flashing Technique has strict distance constraints; the farther the distance, the greater the consumption. Even for Death Dragon General Sinos, escaping from this range is by no means an easy task.
This must at least be the Second Tier skill, Space Transmission Skill!
Space Transmission Skill is similar to Flashing Technique, both are teleportation skills. The former's feature is its extensive teleportation range, and it can perform blurred teleportation, making it a very powerful escape divine skill.
Hang Yu couldn't determine Sinos's location temporarily.
