"Ian NOOOOOOOOOO!" Clark screamed as the wave had gotten too close to Ian.
"Done" Ian said in his mind and the symbol he was drawing with his steele came to life, drawing in a lot of spiritual energy, even from the wave,and eventually formed a large shield made entirely from spiritual energy shining a white hue. Just in time to stop the wave, the shield withstood the wave even until it died down albeit making it harmless for the researchers behind Ian.
"Huh?" Clark along with the other researchers looked dumbfounded. More dumbfounded was the man who made the attack, because after the attack had died and the dusts had settled down he saw Isabelle running towards him and disappear from his field of vision. He copped a hit to the back of his head. "Thank you" Isabelle said facing Kai, who was in front of her.
Flashback:
After kai had finished with the enemy group, he ran to where Isabelle was facing the man. "On time" He said in his mind and proceeded to carry her right after she moved away from the point of attack. He started running as the wave started spreading out and was able to stay ahead. He carried her back after the wave lost the power to harm and before the dusts settled. Isabelle teleported to the man's back by performing a lightning flash and proceeded to knock him out.
After gagging their opponents up. They got to work and mined enough terassium they need. Before they left, they set up devices that will alert them if other shadowhunters come around there to mine their terassium.
Back at the Institute....
"Is this necessary?" Ian asked from inside the tube he was suspended.
