A look of shock also appeared on Xiao Zhentian and Wen Wanrong's faces.
They had not expected that their youngest son had just promised to get along well with his elder brother, only to try to kill him the moment they met!
"Zhentian, stop Lingtian, quickly!"
Wen Wanrong tugged at Xiao Zhentian's sleeve, her face full of anxiety.
A trace of hesitation flashed through Xiao Zhentian's eyes.
With his strength, stopping him would naturally be easy. But his youngest son had repeatedly tried to kill his elder brother and was on the verge of developing a heart demon. If he stopped him this time, it might greatly affect his future cultivation.
At the same time, he did not want to watch his eldest son die on the spot!
For a moment, he was caught between two impossible choices!
Xiao Zhentian's moment of hesitation caused him to miss the best chance to act. Xiao Lingtian had already charged in front of Xiao Chen.
"Zhentian, you..."
Seeing that Xiao Zhentian still had not moved, Wen Wanrong looked at him in astonishment.
The people in the arena were stunned as well.
A tragedy of brothers slaughtering each other was about to unfold, yet the Zhenbei King simply stood by and watched? Was he really going to watch his youngest son kill his eldest son with his own eyes?
What a cruel heart he had!
Just then, Xiao Lingtian leapt into the air, raised his saber with both hands, and hacked viciously down at Xiao Chen.
A terrifying black saber aura clung to the blade like flames, radiating a dreadful presence.
As the saber fell, a violent killing intent filled the area within ten meters.
The long saber came crashing down at incredible speed, intending to split Xiao Chen straight down the middle!
