"Green, three streaks of green energy above my head, ha ha ha!" Bingbing laughed.
"Green energy?" I chuckled. "It seems you still haven't learned precisely. Mine is red energy. Green energy is the fourth rank. It's impossible for me to have advanced to green energy this quickly."
"But... it's clearly green energy," Bingbing said, her eyes crossed, looking at the void above my head.
"It is indeed green energy," Yao Yao stated definitively. "But before you went to the underworld to deliver bullets, you were yellow energy. Now you've directly ascended to the intermediate stage of green energy. It's very clearly green."
I scowled, feigning anger. "Is it because someone cuckolded me during this time?"
The two girls burst into laughter. Naturally, I was pleased. I hadn't expected my true energy level to increase so rapidly. Most likely, it wasn't because I had improved quickly, but because of the dual demon cores of the Whale God and Da Ji within me.
By one o'clock in the afternoon, the sunlight began to weaken, and Bingbing's eyes also became sore, tearing up. Yao Yao then stopped training her energy-reading technique and began to teach us the basic principles of circulating and directing energy.
Bingbing's body had very little true energy and couldn't be mobilized. Yao Yao thought for a moment and asked if I was willing to lend her one of the demon cores.
"...Can this thing be lent?" I furrowed my brow.
"Theoretically... it should be possible, but it requires the recognition of the demon core's owner. Although the demon core is within you, it is actually still controlled by its owner. It's just that they are currently unwilling to manage you," Yao Yao explained.
I took out my phone and called Da Ji in the castle to ask for her opinion. Da Ji's demon core was weaker than the Whale God's and her temperament was more gentle, so Bingbing wouldn't experience rejection.
Da Ji said it was fine. The demon core was mine to give, and whoever I wanted to lend it to was my decision. However, she specified that transferring the demon core required her presence and hands-on guidance. Otherwise, the recipient might suffer qi deviation.
Before Bingbing and I could go down, Da Ji, with her usual gossipy nature, came up, rubbing her palms together, urging us to hurry. She wanted to watch!
Under the vast sky, thankfully, there were many stones on the mountaintop that could serve as cover. Bingbing shyly completed the demon core transaction with me. In the process, Da Ji used the excuse of needing to guide them to join in, driving back the restless demon core of the Whale God.
The entire process left me feeling dizzy, and I didn't remember many details.
However, the final result surprised me greatly. After obtaining Da Ji's demon core, Bingbing also directly reached the intermediate stage of green energy!
"What about me?" I quickly asked Yao Yao.
"Your energy is still the same. Even if both demon cores were removed now, you would still be at the intermediate stage of green energy. This won't change," Yao Yao replied.
"Then why did she..." I looked at the top of Bingbing's head and realized something was wrong. The grass-green of the intermediate stage of green energy had now turned into a light green. Before long, it changed back to yellow. As her energy level descended step by step, it finally turned into ordinary red.
I guessed that when I first traded demon cores with the Whale God at Tianchi, my complexion also underwent such a change, but I couldn't see my own energy level, so I didn't notice it.
With the support of the demon core, Bingbing's ability to circulate and direct energy also improved. After an afternoon of training, by evening, Bingbing's energy had begun to show a faint orange hue.
Yao Yao explained that the pure yin constitution, when present in females, had a doubled effect, as females themselves possessed yin attributes. It was somewhat a waste of immense resources when it was on me.
Coupled with Bingbing's already excellent physical condition, Yao Yao predicted that Bingbing could catch up to my energy level within a week and then reach the bottleneck of green energy. However, she would likely break through the bottleneck first and enter the cyan energy stage.
In the demon realm, cyan energy and above were considered "great demons."
After a day of training, I ate a lot at dinner, feeling as though it wasn't just me eating, but the sea of qi within my body was also absorbing energy.
After dark, the energy in the sea of qi began to backlash against me again, making me feel incredibly restless. I pulled Yao Yao over to balance my yin and yang energies.
