System vs Rebirth

"So, because the poison concentration in the lake is beyond your expectation, you have to take another approach?" The Valley Master frowned, falling into deep thought.

"Yes. We are measuring everything right now, but of course, I'm here not to bring only bad news."

"Hoh? What is the good news?"

"One of our members has the ability of water purification. He might be a Spirit Wielder right now, but after some testing, we can ask him to purify the water. This way, we don't have to drain the lake."

Water Purification ability caught the Valley Master's eyes. "Are you sure about that?"

"Yes. We first divide the lake into fifty sections and ask him to purify fifteen sections per day. If we can ask him to start earlier, then we will only have one day's delay. On the plus side, the city won't be harmed in any way, considering you can use the water immediately."

"But how can I know that his purification ability is working?"

Paul glanced at Ben as the latter brought forth a container filled with water. "This is the sample of the water lake along with the purified one. As the Water Lord, I'm sure that you are capable to test the water whether it still has the poison or not."

Paul nodded. "And if you still can't believe us bringing the right sample, you may check our progress directly. This way, you will be able to see whether the purification works or not."

"That's certainly tempting." The Valley Master thought for a moment. "With your previous plan, the lake needs a few months to recover, but if you can purify it, then the water can be used immediately."

The Valley Master closed his eyes as if he was imagining the entire process. "I'll give the approval if you can prove to me that your idea works. If I'm not wrong, you haven't started the work yet, right?"
