Alex had long since reached the Immortal Origin 6th realm. And then, one day, he consumed a Sunheart and not a single bit of its energy passed into his body at all. It was all turned into Qi.
That was all he needed to realize that he had consumed all the Sunheart he needed. Meaning, his body had improved as much as it could now. The Sun God's Celestial Yang body was now at the peak.
After nearly 18 years since meeting the Tree, he had done it.
He rested for a long moment, surveying his own body.
What had changed?
Something had, but he couldn't put a finger on it. He had long since finished eating the fruit from the Tree of Life, which had improved everything about him from blood to physique. All those improvements were permanent to him now.
And so, whatever had changed now had been after that.
