Sixteen beams of astral light from sixteen constellations. The Qin Wentian now, his soul had a total of sixteen astral gates.
Before this, his true self and avatar each had eight astral souls respectively. Now that they merged together as one, their astral souls actually stacked. Qin Wentian naturally was very satisfied. This meant that he had all the advantages despite fusing back into one. He was able to sense even more law attributes and gain more heavenly daos.
Naturally, this wasn't Qin Wentian's ultimate goal. Godking Xi had said that Qin Wentian had to be able to form an innate connection with all the constellations in the nine heavenly layers and absorb their energy. This was then his ultimate goal. This was clearly more extraordinary than having sixteen astral souls. Once he could accomplish that, he would be able to use all the laws in the world, there would be no cultivation arts and techniques he couldn't learn.
