Mark just finished dispersing the last of the formation and left the remaining to his shadow undead. He exhaled deeply and wanted to move towards where the rank four was when he suddenly felt danger. He squinted his eyes and quickly looked around when he saw three people emerging from the corner of his eyes. From the abundance of the blood energy in their body, he knew that they were demonic cultivator.
He rushed towards them, and when the three got close to him he suddenly felt over-rolling blood energy coming out from them and it began to slow him down.
"Blood art level one, 1st seal unlocking. Body transformation" he suddenly felt their energy became more abundant. The guy suddenly turned shorter and more bulky while the remaining two had a pair of wings growing out from their back.
"Blood meridians, Great" Mark muttered
"Whoosh" Just flapping their wings, they arrived in front of Mark.
