From Aslan's words, Elijah heard Aslan's attitude and determination to environmental protection.

The first pollution created by Terran cities is water resources, and then the desire for land burns the woods, and then the fertility of the land gradually declines under long-term cultivation, and finally reaches the Merlot area, and then as time goes on, It will be completely reduced to a desert.

This kind of situation has not been found in the Merlot area, especially the fruit trees and plum poplar cassava. There is no damage to the fertility of the land. Instead, the soil is solidified and the surrounding environment is gradually improved.

In particular, Aslan and the others produce something called chemical fertilizer, which has greatly improved the fertility of the land. It is said that a farm is already using chemical fertilizer to rebuild the land on a large scale.

"You're here!" Aslan didn't look back, the scent of fragrance alone let Aslan know the identity of the person.

Elijah nodded. When Concas saw Elijah, who had a beautiful face, they were shocked, and then they bowed their heads obediently.

"Lan Mallok troubles you."

Hearing Aslan's words, Elijah couldn't help frowning.

She had hidden her strength for most of her life, but it was completely exposed because of this time.

Because Aslan handed Lan Mallok to her before leaving, he also pointed out her hidden strength.

This was the first task given to her by Aslan, and she had to do her best to complete it.

"You are welcome, you have helped us a lot after all." Elijah said this from the heart.

At least now the elves and half elves have slowly integrated into the life of Merlot.

"That's great, there is just one thing that needs your help." Aslan said bluntly.

Elijah wants to say, you really think of me as a free worker.

"The destruction of the human race to the environment lies in water resources, followed by land, and then the sky." Aslan said casually.

Elijah nodded approvingly.

As for the sky, it is actually air pollution.

"If you want to change all of this, we must work together. I know that your elves have a lot of magic to transform the environment, and I have also researched a lot of magic technologies to improve the environment. As long as we combine forces, we can create perfect human and elves. A paradise of coexistence." Aslan began to draw the pie.

Elijah also listened attentively, and she couldn't help but look forward to her eyes.

"What are you going to do?" Elijah quickly stabilized and said with a smile on her face.

The magic of changing the environment is not difficult. In fact, many human magicians have also developed that kind of magic, but most of them play as tricks and are mainly used to transform their own living environment.

Therefore, the leakage of environmental transformation magic does not have much impact on the elves.

Moreover, the environment can really be transformed successfully, and the natural power can be slowly restored. For their elves, there are only advantages and no disadvantages.

"Land reconstruction is already in the experimental stage. I hope you will take the time to pay attention. Sewage treatment is the main problem now. The daily sewage produced by hundreds of thousands of people should not be underestimated. A little carelessness will destroy the surrounding area of ​​Melo Town. Existing environment." Aslan said solemnly.

"What about the sewage treatment plant you are talking about?" Elijah asked curiously.

"The domestic sewage in the entire Merlot Town will be discharged from the sewer to the sewage treatment plant, and then the sewage will be treated through several processes. I divide the sewage treatment into three levels."

"First-level treatment: I call it physical treatment. Through mechanical treatment, such as grille, sedimentation or air flotation, the stones, sand, fat, grease, etc. contained in the sewage are removed."

"Secondary treatment: Magic element treatment, the pollutants in the sewage are degraded and converted into sludge under the action of microorganisms."

"Third-level treatment: the advanced treatment of sewage, which includes the removal of nutrients and the disinfection and purification of the sewage through the light magic."

Elijah's eyes brightened when she heard it, and this set came down again, and the originally filthy water could be recycled again.

After all, Sinoland does not have so many chemicals, and a lot of sewage can be used without going through tertiary treatment.

"Then what do you need me to do?" Elijah asked urgently.

"Help me plan the sewage treatment plant and supervise the environmental pollution in the Merlot area. Any large-scale environmental pollution behavior must be severely cracked down." Aslan said firmly.

Elijah glanced at Aslan and said slowly, "Then how to deal with the pollution in your industrial areas?"

Aslan asked in a word, speechless.

It is absolutely impossible for the cement plant and steel plant to stop production, it is related to the rapid development of Merlot.

"I will install waste gas pollution treatment equipment in the steel plant as soon as possible?"

This did not make Aslan feel embarrassed, because in his previous life he worked with an elven tribe to restore the environment of the Merlot area to a standard suitable for elves to live in. At that time, he also developed a lot of pollution treatment equipment.

The biggest pollution of the steel plant is the exhaust gas emitted by the huge chimney every day. Because the scale of the steel plant is still small, Aslan did not care too much. Since Elijah proposed it, then he showed his determination to prove it. Show him.

"I discovered a special material two years ago. I call it activated carbon. The activated carbon is made into a huge adsorption device, and the organic waste gas is sent to the adsorption device by the exhaust fan. The organic waste gas is adsorbed by the activated carbon device in the adsorption device. The gas is purified, and the purified gas is discharged to the atmosphere to complete the purification process." Aslan said confidently.

Elijah was in a dull state.

Everything Aslan said today, the knowledge contained in them is richer than those of the elves who have been studying and protecting the environment for thousands of years, or even longer.

"Are you really a human?" Elijah asked subconsciously.

"Of course, but I am a human who loves nature." Aslan laughed loudly.

Elijah also looked at Aslan with a smile, with a different look in her eyes.

"I will establish an environmental sanitation department as soon as possible. You will be the chief environmental sanitation officer, responsible for environmental sanitation throughout the territory, and all personnel will be recruited by you," Aslan said.

Elijah nodded.

"Then I will go back and make plans. Two days later, I won't give it to you in three days."

Aslan nodded, and Elija left quickly.

Konkas talked and stopped, only Kluzer and the others took it for granted.

In a short while, a group of tall people in heavy armor came.

Just at the first glance, Concas can't do without his eyes.

He had long heard that Lord Merlot had subdued a group of barbarians, and now it seems to be true. Look at the terrifying armor on them, at least one or two hundred catties!
