Refining Pangu's Heart Blood was an extremely lengthy process, and Sha Chen was prepared for a long-term refinement. However, as he refined it, the strength of his physical body continuously grew stronger, and his power became immense. It was as though he was cultivating his physical body, and the rate of cultivation was even faster than before. This was because he was refining Pangu's Heart Blood; a single drop could penetrate mountains and rivers and span through ages. Not to mention, Sha Chen was refining a whole cluster of it, an amount unprecedented and rarely seen throughout history. If he could completely refine it, Sha Chen felt that even if his physical body had not fully reached the Great Perfection of Primeval Chaos, it would not be far off. By then, under the heavens, perhaps only Saints would be his match. Even Tathagata could be challenged without defeat. The formidable power granted Sha Chen tremendous confidence, as well as a powerful belief and hope.
