The Heavenly Serpent Beast Emperor often cultivated in the Divine Land and has always been mentoring the Qing Sheng Beast King... Their relationship was extremely close.
As for the Hei Jing Beast King? He too was considered his junior.
"Agreed,"
"The Beast Emperor only ordered us not to invade the human main city," said Chi Yen Beast King, "I will gather another group of Beast Kings... specifically to ambush him."
"Good," the Qing Sheng Beast King's eyes lit up.
He was well aware that even Hei Jing had died at the hands of that human Martial Artist; if he relied solely on himself, winning was impossible.
But with Chi Yen Beast King's help, there was hope.
The Qing Sheng Beast King remembered what his father had said before, that Chi Yen Beast King was the most likely in the entire world to become the fourth Beast Emperor.
"However, once this human is slain, you must return with me to Ming Mountain," Chi Yen Beast King intoned deeply.
"No problem."
Very soon.
