Jiang Shuyi sent a composed smile as she sat on the mat next to Lu Shu. Everyone turned their heads to look at Jiang Shuyi, where the sound had come from. Those words seemed like thunder in an empty room, shocking everyone into silence.

Unraveling the mystery for A-level students, it took them three hours to complete a minor heavenly cycle. For B-level students, they could finish one in just a day—specifically, one night. Everyone was now aware of this fact.

According to theory, 24 hours were enough time to complete two minor heavenly cycles. But after a full day's practice, everyone realized that the efficiency of practicing at school paled in comparison to doing so at home.

Some people had vague knowledge about what might be happening, while others remained clueless. They couldn't understand how Jiang Shuyi managed to complete two minor heavenly cycles in just one day—this was a speed increase of almost double Ruli's rate. Going higher still, only someone like Cao Qingci, an A-level student, could match this pace!

Lu Shu smiled. His classmate had made such a startling debut without a sound. No wonder she knew so much about paradises and theories. Perhaps... she found a great place to practice?

Xifei looked around the classroom with a calm voice: "The speed of cultivation I mentioned was under standard conditions, but there are other factors as well. For example, your living environment might be rich in natural energy."

"A place abundant in natural energy is not just beneficial for human cultivation; it can also affect animals and plants. This is an established fact—we have discovered that all such places will result in anomalies among plants and animals. Jiang Shuyi must have found a suitable place. His home's location might be unique, which is entirely normal," Xifei explained. The others fell silent, realizing... the environment for cultivation was not fair either!

Xifei continued speaking: "Not just the environment, but also the resources available. When I gave out spiritual stones, you all saw those glowing rhombic stone pieces? That's what they are called—spiritual stones. Each piece contains a great deal of natural energy and is easy to absorb. Practicing with a spiritual stone, even a B-level cultivator can match the speed of an A-level one. Of course, it cannot be used indefinitely."

"Other resources include medicinal pills and foods that grow in areas rich in natural energy. These also play similar roles, but medicinal pills are the most effective. As long as you follow the progress of Dao Yuan Class, excellent students will receive a regular and quantified quota from the state to aid your cultivation. However, both spiritual stones and medicinal pills have some side effects, so they won't be given in large quantities to prevent any regression in cultivation."

After such a long explanation, it essentially meant: "Be good boys and girls, and you'll get more treats later!"

But there was something Lu Shu didn’t quite understand. He could see why medicinal pills had side effects—after all, they were drugs with toxic properties. But spiritual stones? Why would they have side effects as well?

He wondered about the standard for distribution; he himself was at F-level and wasn't sure if his chances of getting one were high.

At this moment, Lu Shu recalled a post on the forum saying that many mountain mines had been sealed off—might it be to collect spiritual stones? This rhombic shape didn’t seem natural. It might have been cut for easier measurement?
