However, through this ordeal, Li Zhirui also discovered that the Substitution Technique was far more formidable than he had imagined; even Tribulation-Transcending Cultivators couldn't detect any flaws!
Apart from danger, he also gained considerable benefits over these years, with substantial improvements in his realm and cultivation levels, especially his Dharma, which increased from twenty-five zhang to a full three zhang, bringing him one step closer to the thirty-three zhang barrier.
Among other gains, the most precious was eight-rank Taisui Meteoric Iron obtained from a meteor that fell from the sky!
It contained rich Wood Attribute Spiritual Energy and was incomparably hard, thus it was immediately merged by Li Zhirui into his Life-bound Magic Treasure, Thousand Spirits.
