Within the Pill Realm, Xiao Fan narrowed his eyes as he watched Old Man Mu Gu flee, a trace of regret flashing through them.
Xiao Fan had originally intended to finish Mu Gu off right there. Only after they exchanged blows did he realize just how difficult it was to kill a Dou Zun. Dou Zun experts had honed their command of spatial force to perfection. Unless the gap in strength between them was enormous, once one side decided to flee, they might not escape unscathed, but their chances of escaping alive were still very high.
When Old Man Mu Gu first appeared, Xiao Fan had tried to lock down the surrounding space, intending to kill him on the spot. But once Xiao Fan made his move, he discovered that the energy upheaval caused by a battle between Dou Zun experts was simply too powerful. Sealing space during such a battle required an exceptionally profound mastery of the spatial path. Otherwise, the seal simply could not withstand their clash.
That was also why Xiao Fan had not immediately stepped in to help when Old Man Mu Gu attacked Yao Lao. He had been busy sealing the surrounding space, but the final result was clearly a failure.
Thinking back now, when the Heaven Demon Phoenix Clan and Wind Lightning Pavilion had encircled him, his success in killing that Heaven Demon Phoenix Clan Dou Zun expert had owed something to luck. His opponent had also underestimated him, giving Xiao Fan an opening. By the time that expert reacted, the assault of the Five-Wheel Flame Disk had thrown the space around him into utter chaos, leaving him unable to escape. In the end, he had taken Xiao Fan's attack head-on, never expecting that he could not withstand it at all, and had died
