"Soul Core? What is that?" Qian Renxue asked in confusion. "Though from the name alone, it does sound similar to the effects of Dugu Bo's dan bead."
"A long time ago, my family had a Soul Douluo expert who had just entered Rank 90. While hunting soul beasts, he encountered a severely wounded Hundred-Thousand-Year Soul Beast. That beast traded the secret of Soul Cores for its life." Shi Yueyi explained, "In other words, this can be considered a blind spot in the cultivation of human soul masters."
"The reason Hundred-Thousand-Year Soul Beasts are so difficult to kill is because they have Soul Cores supporting their strength." Shi Yueyi spoke as she recalled the details.
"This is your family's secret. Is it really appropriate for you to tell me so casually?" Qian Renxue hesitated. She would be lying if she said she was not tempted.
But everyone in the world of soul masters was selfish. Any secret technique or other treasure was passed down to one's children, never to friends, no matter how close they were.
Shi Yueyi's face reddened.
How could this be her family's secret technique? It was merely knowledge she had brought back from ten thousand years in the future. But to make Qian Renxue believe her, she could only put it that way for now.
Still, she had not claimed it was her family's original creation. She had said it was learned from soul beasts.
In fact, that might truly have been the case. Over ten thousand years of development, humanity had learned about Soul Cores from soul beasts, allowing human soul masters to gradually become more adept at facing Hundred-Thousand-Year Soul Beasts.
"It's fine, it's fine. I'm the only one left in my family anyway. Who I pass it on to is entirely up to me.
