Shang only had around 6,000 years left, and he couldn't waste any time.
Yes, summoning an Abomination King was extremely dangerous, and it might even open the door for more Abomination Kings, but Shang was willing to take the risk.
To reach supreme power, no sacrifice was too big, and no price was too steep!
"I am going to summon an Abomination King," Shang said.
Naturally, since this was the Lightning Emperor's Isolation Barrier, the Lightning Emperor heard him.
The Lightning Emperor didn't immediately answer, and five seconds of silence passed.
"Okay," he answered.
The next moment, a portal opened above the Isolation Barrier, and the Lightning Emperor stepped through.
An Abomination King was extremely powerful, and if anything went wrong, the Lightning Emperor would need to get involved personally.
