The arrival of the Demon King

From the letter that he deciphered, Lu Qing clearly saw the person who had requested the three brothers to defend the city for half a year. The heavenly spirit blood eagle was their father.

This was indeed the case. The only thing that could make these three guys resist to the end without caring about their lives was the direct connection between their bloodlines outside the power of the demon race.

The heavenly spirit blood eagle, Yin Liang, was a peak level-four Great Demon King. According to the information that Lu Qing had received, this Great Demon King should have been fighting with Jin country on the Western battlefield of the northern wilderness forest.

If it was just this guy, he didn't have to worry too much.

Coming to the East with Yin Liang was 'White Night beard' lang Xi. This person's strength was on par with Yin Liang's.

Two peak Tier 4 mayflies were a little scary.
