(WARNING: VIOLENCE >>> I think describing the situation after or during the explosion may cause discomfort)
The innocent citizen holding the bomb is inside Nadira's mental barrier!
Nadira had to think fast and pull back from her mental barrier to cover herself, Mu Liang, and the few citizens who were next to her.
Mu Liang became very anxious and ended up releasing some of his mental power, but even some of his mental power was too great and the tunnel floor shuddered, luckily the bomb's force was mitigated, which caused some relief for Nadira who she shuddered to think if the bomb had exploded so close to her.
