"Just a few drops of blood, huh?" Bai Jingshen nearly laughed out loud. "I wonder if you would say the same if you knew the significance of those few drops of blood."
"Significance?" Alex got curious. "It's just White Tiger's blood anyway. If I ever want it again, I'm sure I can get it some other way."
"Can you?" Bai Jingshen smiled at Alex mysteriously.
"What do you mean? Why can't I?" he asked. "Is it White Tiger's blood? I know it's rare here, but if I ascend, I should have many ways to get it, right? Whether it be by using money, or maybe even other nefarious means if need be."
"I'm afraid if you lose this blood now, you will never get a White Tiger's blood essence this good," Bai Jingshen said and then he spoke directly into Alex's mind. "After all, these few drops of Blood Essence are comparable to the Blood Essence of the progenitor of the White Tiger, the very one that was blessed by the gods."
"What?" Alex shouted out loud in disbelief.
Whether you guessed it already or not, this book crosses over a little with my other book 'Reincarnated as an Energy with a System'. You can go check out chapters 875-900 to see what Ning Ruogong was doing while he remained in this universe. Although I would prefer it if you read the entire book, you don't need to.
Beware that it does contain some slight spoilers for future plot points too. If you only wish to experience Bai Jingshen's storyline, you can start at 896.
If you want the whole experience, including Bai Jingshen's journey on earth, you will have to read till 941. You will even get a hint as to why Alex's family is as crazily overpowered as it is. No definite answers tho.
