"When did that happen...?"
Xin Ya's voice was chilling. Despite the beautiful weather, it made people inexplicably shiver. Xiao Hei instinctively ducked his head, but the next second, he suddenly came to his senses...
Why the hell am I feeling guilty?
"Ahem..." Xiao Hei sighed. "I reached Level 5 ages ago. It's been almost two months—didn't you notice? Then again, you haven't trained since coming back, and you're not even Level 4 now. It's normal that you didn't notice..."
"I..." Xin Ya's breathing caught. She bit her lip. "But... you haven't done anything either. Usually, it looks like you don't do anything at all. How did you level up so quickly?"
"Who said I haven't done anything?" Xiao Hei immediately perked up. "Look at those fields outside. They're being taken care of so well. Those are active plants—they have to be cared for like babies, and their trace elements have to be replenished constantly. Who do you think's been doing that? And who do you think has been keeping this estate in such good condition?"
"Aren't the Elemental Spirits doing it?" Xin Ya asked blankly.
"Come on..." Xiao Hei covered his head. "Then who do you think is controlling the Elemental Spirits?"
"They need to be controlled?"
"What, do you think they're robot vacuum cleaners?" Xiao Hei laughed. "Once they're charged, you can just leave them alone? Besides, even robot vacuum cleaners need to be charged. Where do you think the Elemental Spirits get their energy from?"
"There's a reason Flower Spirits get tired so easily..." Chen Shanshan explained from the side. "A huge amount of Mental Strength has to be used to maintain the stability of the Elemental Spirits. If you want them to do things, you also have to spend a great deal of energy operating them carefully.
