"This isn't meant for intellectual leisure or entertainment."
Old Kui appeared sometime unnoticed and said quietly. Then, glancing at Mr. Zhuang with a hint of hesitation, he added,
"At least not for ordinary people."
Mr. Zhuang frowned slightly, "Have you ever seen a cultivation technique like this?"
Old Kui lightly shook his head, "I've seen stranger cultivation techniques, but one as peculiar as this, I haven't…"
"I've encountered bottlenecks involving Spirit Stones, Spiritual Roots, Spiritual Objects, meridians, bloodlines, and even techniques that require killing people, slaying Monster Beasts, or Demon Cultivators, and ones that rely on living blood qi, Spiritual Power, and Divine Sense. But a bottleneck tied to a Mystery Formation within the Sea of Consciousness—this is the first time."
Old Kui added calmly, "These ancient obscure cultivation techniques are likely only found among your Ancient Sect types who stubbornly stick to the old ways."
