Though he thought this, the Heaven Devouring Demon King sent a message: "Second Brother, your heart is as clear as the sun and moon. I, your third brother, am ashamed that I can't compare. That little brat Wenjie may be useless, but I still can't bear to abandon him. In my view, we should wait a little. This turtle-shell formation relies entirely on those bastards sustaining it with their magic power. They'll run out eventually. Xu Yi's taking this opportunity to rush his breakthrough, but even if he succeeds, he'll only go from a little bug to a big bug. It's not as if he can become an immortal in one leap. We can let him continue, and lull him into thinking he has us over a barrel. Then we can catch the little thief off guard."
Demon King Kui Li found the argument convincing. Though Xu Yi had turned a hopeless situation around and shocked him, he had no doubt he could crush Xu Yi with ease. Even if Xu Yi really reached the fourth realm, he still wouldn't pose a threat. Waiting a little would cost them nothing.
Still, he knew the Heaven Devouring Demon King's plan. Even if they acted according to it later, he would be the one charging in first. The Heaven Devouring Demon King clearly had no intention of fighting; he wanted his son to live.
Xu Yi, evidently, was also happy to use Shi Wenjie to keep the Heaven Devouring Demon King in check.
In other words, after all this scheming, he, Niu Gangfeng, was the only one who would do any fighting, while the Heaven Devouring Demon King merely had to think.
Even brothers shouldn't scheme against each other like this. A trace of irritation stirred in Demon King Kui Li's heart.
