Blood Sea Thunder Formation.
When the formation was activated to the extreme, the blood lightning above and the blood sea below would explode, shattering all the enemies trapped in the formation.
However, due to the impact of the blood sea below, the explosion of the blood lightning above would be limited to a certain range.
Therefore, the blood-red lightning would not fall on the ground and harm the commoners.
In the eyes of the world, it was like a series of thunderbolts exploding in the air.
It was precisely because the power was concentrated in the Blood Sea Formation and attacked from top to bottom that it was so powerful that even a peak Martial Saint at the eighteenth realm might not be able to escape unscathed.
Those who were slightly weaker would have no chance of escaping. Even Martial Saints would only have death awaiting them.
The Little Sword Immortal Shen Tianzhao's sword broke the lightning ball in advance.
