Fortunately, Davis Loret was indeed Tian Long's next incarnation. Otherwise, the result wouldn't have come out positive. He was not kicked out, nor did any untoward thing happen after the formation activated. The flash of blue light obviously meant that his soul contained the similarities; that he was undoubtedly an Alstreim not only at the level of the blood but also at the level of the soul.
His own soul, which is Tian Long's soul, possibly couldn't have a relation to the Alstreim Family. Only Davis Loret's soul has a relation to the Alstreim Family. However, he was not aware of what happened to it when he possessed this body with the help of Fallen Heaven, whether it had disappeared or assimilated into him, at least until now, where it became apparent.
It became clear!
