The 'Dragon-slaying power' should have been given to him by the laws of heaven and earth, but song qingxiao did not hide it from him at the critical moment. After experiencing the forgotten soul-subduing clan and uncle Xiang's greed for immortality, he once again had a good impression of the human he 'protected', and thus gave her this power.
Such a heaven-defying power did not return to the world with the disappearance of their clansmen. Instead, they were concerned that after the Chang clan was exterminated, their inheritance had fallen into the hands of song Qing Xiao.
Even though song qingxiao's strength was limited, she could only use a small part of the true power of the 'Dragon-slaying power'.
However, the 'power of Dragon extermination' was a heaven-defying power that could restrain ancient demons. Even if song qingxiao could only unleash one-ten-thousandth of its power, the beast King already had a bad feeling.
