The Demon King of Bull, who had arrived ahead of schedule, had already failed three times under Qin Jun's feet. This time, due to the system's forcible modification, his loyalty had changed to eighty, and who knows what he was thinking.
Qin Jun was looking forward to meeting the Demon King of Bull again.
"Tsk tsk, if Tathāgata or Donghuang Taiyi were summoned, that would be even more dramatic…,"
Qin Jun thought with a bit of mischief, and right after that, the system doused his enthusiasm, "With the host's cultivation, summoning the Demon King of Bull and making him loyal to the host is no problem, but if it were Tathāgata or Donghuang Taiyi, that's not a certainty."
To this, Qin Jun just curled his lip.
This principle is the same as summoning a god and demon that's too powerful; the system's influence is not stronger than their true nature.
