In the blink of an eye, five days went by in a flash. Grey and Klaus were still seated at the side of the small river.
Initially, Klaus was the first one to have a reaction while they were both trying to comprehend the mystery behind the heavy water, but due to Grey not being a noob to things like this, he quickly caught up.
Nevertheless, Klaus was still the one with the most elemental particles around him. Within a one-meter radius, everything around him felt extremely heavy.
Klaus' comprehensive ability was no joke, in a matter of five days, he had gotten a good chunk of what was needed. He could even exit cultivation now, but he wanted to ensure he got the best out of it.
