In the bedroom, rose petals were scattered like fallen red leaves.
Lu Li lay on the bed, glanced at Liu Kexin, who had gradually fallen asleep, and revealed a slight smile.
Reaching his current state, theoretically speaking, no matter what he does, he shouldn't feel fatigue, nor need to rely on sleep to recover.
Yet at this moment, he felt somewhat exhausted.
Because a significant amount of energy had been expended.
"I probably used up ten percent of my energy, and considering the ten percent used today to sustain myself, that's a total of twenty percent."
Lu Li instinctively took a deep breath, "The fortunate thing is, I've already ensured Kexin is pregnant."
In fact, doing certain things doesn't consume much energy.
The reason he used so much energy was entirely because he wanted Liu Kexin to conceive "cross-species."
Indeed, evolving to this extent, he had created a "reproductive isolation" with ordinary humans.
It couldn't be strictly called reproductive isolation.
