If it had been another Heavenly Connection realm cultivator facing these four Dao embryos that had already communicated with the Heavenly Dao, they probably would have been defeated utterly at the hands of the man with the split head.
That's because each of these four Dao embryos, taken separately, was very powerful!
Whether it was the Thunderclap Majesty that relied on brute force to win or the unpredictable Heartbeat System, without the appropriate countermeasures one would surely be killed.
Unfortunately, the man with the split head picked the wrong person. If he had chosen someone else from the Human Race, his ability would have been acceptable, but stripping a person of the Human Race of their system ability and then using it against Xiang Beifei was a dead end.
