Rean then looked by the side as an assistant brought a bucket with him. Inside, there was dirty water from the sewers. Obviously, the formation masters narrowed their eyes since the smell was anything but good.

"Hahaha! It's quite filthy, I know. However, this formation can take care of it."

​​

Rean quickly poured the water into a tank linked to the formation. Little by little, the formation absorbed the Spiritual Energy of the surroundings as it worked. On another side, there was another tank where clean water fell.

Rean really liked the cultivation world. The runes worked perfectly in this place. As long as the formation was set up correctly, it would give back only pure water, which was nearly an impossible task back on Earth. However, Rean didn't do that. He at least knew that 100% pure water wasn't good for one's health. He also made sure to keep the balance of minerals inside the purified water similar to that of river water.

On the other side, the impurities from the sewer water were separated. After all, Rean couldn't make it simply disappear, nor did he want that. That kind of impurity was great for the soil, which could be used for farming. Farming was the foundation of ordinary people's lives, so it was beneficial for them.

Turin looked at the process and couldn't help but ask.

"This is quite slow, no?"

Rean nodded.

"It is. I can tell that you don't seem to like it very much. However, I didn't do it for the cultivators. Any cultivator, even those with no Water Element Affinity, can still use the Water Element to create some water. But the truth still stands that the majority of people can't do that. Only at the Foundation Establishment or above would you have enough control for that. Besides, it's a very boring and exhausting task if we had to use cultivators to generate water. Otherwise, the cities wouldn't use rivers, wells, etc. No cultivator wanted to spend their time doing such a thing."

"This kind of self-working formation would be life-changing for the ordinary people. Besides, the formations themselves are very simple, so it can be made to be moved around."

Rean looked at the examiners' expressions and couldn't help but sigh inwardly.

"Are you disappointed because only those at the bottom can use it?"

He already made his mind up that he wouldn't care if he lost because of such a reason. Nevertheless, it was sad to see these high-level cultivators ignoring the fact that they were ordinary people in the past.

However, Turin shook his head as he replied.

"No. It's just that I can't understand how you got the water separated from the filth. This set of runes... seem somewhat different."

Saya agreed with him as she said.

"It somehow reminds me of the Communication System, but how..."

"Ah!"

Only now did Rean notice that they were right. He did use an approach similar to the Electrical Formations. No wonder they couldn't understand. After all, it probably didn't exist before, to begin with.

"The elders are right. It does use a similar structure."

Saya couldn't help but ask.

"But why? Wouldn't it have been better to focus on water type purification formations instead?"

Rean scratched the back of his head in response.

The truth was that he planned to transform it into a Circuitry Formation in the future. In the end, he made it in a way that such an upgrade would be more straightforward. However, it did really look that it had many unnecessary points because of that.

"Well, it's as I said. This Water Reclaimer Formation is far from perfect. I intend to use a similar system in it in the future."

Turin was surprised after hearing that.

"Can the Lightning-type Communication Formation be used in a Water-type Formation? Would it work?"

Rean shrugged his shoulders as he responded.

"How would I know? This is just an idea. However, it does work, as you can see. I'm confident that I will make it more energy-efficient in the future."

Rean finally sighed in relief, seeing that these elders were just puzzled about his approach and not that they found it useless.

"Can you see the practical uses of it? It is possible to set up huge water reclaimers in the city. Although more Spiritual Energy would be necessary, it would save a lot of time moving water around. Nonetheless, this formation is focused on those who live outside the cities, like the tribe I came from."

Saya nodded, quite satisfied.

"That's a good formation. We must never forget that ordinary people are the foundation of the world we live in. If their quality of life is improved, so would the strength of the empire. It's hard to see which one is better, yours or Havek. Havek's formation is more suited for big cities, while yours is a must-have to those who live in the wilderness like the tribes."

Havek watched the master talked from a distance and nodded. He could also tell how useful such a formation would be. However, Rean's formation had an effect that his own didn't. It was directly linked to people's lives. People could go without light for the night. After all, the next day would always come. Worst case scenario, they could still use torches. However, clean water wasn't easy to acquire anywhere, especially in a medieval place like the cultivation world.

The examiners then began to ask more questions regarding Rean's Water Reclaimer Formation. They also pointed out what they thought to be wrong and what could be improved. Finally, they complimented his idea before moving onto the next one. They wanted to ask more questions as to how Rean would implement something similar to the Communication System into this kind of formation. However, more people were waiting to have their formations judged, so they had to move on.

Rean then returned to the area where the other participants stayed with a smile on his face. His opinion of the Formations Guild, especially Saya, had improved after what she said.

Qia then quickly hugged him, not caring about everyone's gazes.

"You did great!"

Rean laughed in response. He knew that it would be impossible to stop this girl when there were more people around.

Havek also came forward to talk.

"As expected. I'm looking forward to what that thing can turn into."

Rean then looked at Havek as he pondered over something.

"Havek, I have a proposal for you after this competition is over."

Havek showed a puzzled expression, but nodded in the end.

"Fine. This god shall give you some of his precious time to hear what you have to say."

Qia couldn't help but ask.

"What about me? Don't you have anything to say?"

Rean felt helpless as he nodded.

"Of course, my love. Your Multi-teleport Formation System was incredible. I couldn't be happier to see such a marvelous invention. I'm sure that many companies in the world would be interested in it once you finish improving its size and energy consumption."

Qia nodded with a smile as she said.

"But of course. How can I fall behind my husband when it comes to formations? I can already see how many impressive formations we can create."

The examiners continued on their tests as many good ideas appeared. Of course, there were failures as well. But in the end, the Formations Masters were satisfied.

"Very well. We will discuss between ourselves to decide who the ten cultivators with the best ideas are. The results will be announced in one hour. Look forward to it."
