The moment the room exploded, a huge shockwave was released from the room.
Varian teleported in front of the giant room or where the room once was. Now, it's filled with dust and pieces of metal lying all around.
The shockwave was also just exiting the room, but in a single second, it'd reach every corner of the ghostship. Even though it was only a fraction of the energy responsible for blowing up the walls, it was strong enough to wreak havoc in the ghostship's interior.
To prevent chaos, Varian folded his hand and channeled his powers.
The space around the room solidified and the shockwave that was just exiting the room suddenly slowed down. Then, a hemispherical ice barrier sealed up the whole area and a lightning net was suspended as an additional guarantee.
The shockwave was contained and Varian was about to sigh in relief when lights of myriad colors lit up in the ghost ship.
