Sato's hands were covered in fresh blood, yet his face was twisted into a bizarre smile.
He ignored Gu Yuexi, quickly crouching down. Using the blood from the two still-steaming hearts, he rapidly drew an incredibly complex, blood-red sigil on the ground!
The sigil looked like a writhing snake, exuding an ancient, evil, and nauseating aura.
"What is he doing?!"
Outside the arena, in the Great Xia mentors' section, Chen Shanhe shot to his feet. He stared intently at the bloody sigil, his pupils constricting.
"Is that... the Sakura Country's Forbidden Technique—Blood Contract Summoning?!"
"This is bad! It's a Forbidden Technique that uses the blood of a Divine Beast as a catalyst, sacrificing the flesh, blood, and soul of living beings to forcibly summon a powerful Demon Beast!"
"Quick! Gu Yuexi! Stop him!"
Chen Shanhe roared in desperation, nearly charging in himself.
But he couldn't get through.
