Destroying The Barrier

A whole hour passed by and the energy accumulated by the red Skystone kept increasing. 

Huo Shihong was already having a hard time on his task to keep the whole formation active. The energy kept increasing, getting so powerful and unstable, that he was almost losing control of the red Skystone. 

He decided that it was already enough, since the capacity was already reaching the power a Mana Control late-stage realm expert would release when attacking. If he decided to use this cannon on anyone here, it would be a sure-kill move. 

"It's enough! I thank for all the help you guys gave me to activate this formation, but I would recommend that everyone get a bit farther to protect against the impact." 

The practitioners could feel the intensity of the energy inside the red Skystone, it was pulsing and emitting a bright crimson light. All of them decided to move to at least a kilometer away from the cannon.
