Surprise Hotel

The man smiled and took out the badge pendant hidden under the worn-out clothes.

When he saw the emblem above, old Jason's eyes suddenly brightened.

"Er Dongchuan, a researcher in the 81st District of the Underground City, focuses on water purification and microbial technology. But this is all many years ago." The man smiled.

"I was also a member of the 81st District of the Underground City, engaged in mechanical design and development." Old Jason stretched out his hand, "They all call me Jason, and my proper name is Lu Yuanjie!"

"The developer of the heavy mecha [patrol guard]? Disrespect and disrespect!" Er Dongchuan was inexplicably awe-inspiring, making Lu Xing and Xianuo puzzled.

After thinking about it carefully, Lu Xing guessed that it should be the old Jason's unknown past, and perhaps there are many great achievements hidden in it, and people will be awed when they hear the name.It is not so surprising to think that he can easily repair a mech that only the high-ranking commander of the camp can drive.

"Back to the topic." Lu Xing interrupted the conversation between the two, "Mr. Er Dongchuan, these days, have you just planted green algae to purify water?"

"Of course it's more than that, please follow me." Er Dongchuan smiled mysteriously and led the way.

In just a few days, the agricultural base has undergone many transformations.

Several giant water tanks were installed in Lab 1 and connected by pipes.

"What is this?" Xia Nuo asked, pointing to the jugs.

"The filtering of radioactive substances in the pool is just a basic experiment. These are the equipment officially put into use. Grand Duke Lu Xing once said to other assistants that I will try my best to satisfy whatever I want. This allows me to do this here smoothly. In the filtered water tank, I added more than one kind of algae, which can adsorb iodine, cesium, plutonium, strontium and other radiation materials, and the filtration degree is as high as 95%, and then the water with traces of radiation materials is transferred Enter the next water tank for secondary filtration. In this step, the main methods are electrolysis, microbial technology, super compression, etc. I won't explain to you the steps that are too detailed because they are too complicated." Er Dongchuan As he walked, he said, "After that, the water is transferred to the third-stage tank for physical filtration, so that the contaminated water is filtered into pure water. The fourth-stage tank is distilled, and the water coming out here can be directly drunk. I Knowing that drinking water for residents in the city-state is also a big problem, so I reserved a water intake here."

"This is really great!" Lu Xing gave Er Dongchuan a thumbs up, "Solving the drinking water problem means solving most of the people's livelihood problems!"

"So as long as the groundwater is brought in, it can be filtered?" Xianuo asked.

"Theoretically, there is no problem. Water that takes 30 years to naturally attenuate radiation can be consumed normally within three days after passing through a complete set of water purification equipment. However, due to storage issues, it is not yet possible to produce purified water on a large scale. "Er Dongchuan answered.

"It's a pity that I haven't taken a shower for a long time, and I wipe it with the dry cleaning foam of chemical bath detergent every day. I really want to experience the feeling of being watered!" Xianuo grumbled.

"I didn't dare to make promises before, but now with Mr. Er Dongchuan, as long as we expand the water purification production line, we can do it with extravagance!" Lu Xing laughed.

"I have a question." Old Jason pointed to the fifth water tank and said, "The fourth level has already been distilled, and it can even be used. So what is the fifth level water tank for?"

"The fifth-level water tank is filled with nutrients and can be directly led to the test shed." Er Dongchuan said, pushing the door at the end of the laboratory open. After the door was opened, it was an endless planting shed.

The three were dumbfounded.

The planting shed is divided into multiple areas, and each area is divided into the types of plants grown.

But basically all edible crops are grown.

For example, the cabbage test field is the closest to the three, followed by the potato test field, and then the corn test field, next to it is the peanut planting field and the sunflower planting field... There are more than a dozen species in total.

And these seeds, obviously, Durdongchuan brought them from the underground city.

The water pipes that extend from the No. 1 laboratory are directly connected to the water tanks placed underground in the test shed. The water tanks are flat and connected to each other. Above the water tanks are regularly arranged seedling holes, and green plants exist in each hole.The water flow will eventually circulate back to the filtration system and be reused.At the same time, the planting shed is equipped with water collection equipment, and the water evaporated to the roof of the shed can be recycled.

This is simply an ingenious design!

"It's amazing! These plants have grown so big in such a short time! These cabbages can already be fried with mushrooms!" Lu Xing said in surprise, "Right, do you have mushrooms?"

"Not yet, and follow-up research is needed. Cultivating bacteria is not difficult." Er Dongchuan replied.

"You are a genius!" Lu Xing excitedly looked at this experimental field, "I am going to add you as a special talent in the camp. You can live in the palace room in the future. Food and water are all special supplies. If you have any requirements, please follow me. To your assistant to mention it!"

"I won't live in the palace. I live in the agricultural base and feel more at ease. Because the nutrient solution is better prepared, vegetables can be supplied to the market within a week at the earliest, potatoes need about two weeks, and cereals need a month. "Er Dongchuan said, "In addition, if there is a need to build a new pure water treatment plant, I am also willing to help."

"Great! You are simply my lucky star!" Lu Xing held Er Dongchuan's hand excitedly.

And Er Dongchuan's eyes also had some admiration, and said, "I am also grateful for your kind acceptance and generous gift of food. This camp is the most humane I have ever seen, and civilians are eligible to participate in the proposal. I am very happy to be able to use my abilities here!"

With both hands tightly clasped, Lu Xing realized the power of kindness and trust at this moment.

Er Dongchuan decided to live here, and he did not stop him. A person who is obsessed with his career is worthy of respect.

When he left, Lu Xing instructed his subordinates to arrange room, furniture and daily necessities for Er Dongchuan, and asked the craftsman to tailor new clothes for him.

[The task of planting crops has been completed, and one thousand energy spars will be awarded.

Good guy, I actually rewarded so much this time!Sure enough, the harder the task, the more generous the reward!

[New task 1: Find a way to get 10,000 bottles of purified water.

[New task 2: The city has a dry climate and creates an artificial rainfall.

Seeing these two new tasks, Lu Xing couldn't help but raise his mouth slightly.

With the new water purification system, these are no problems at all!

Only one day later, the water treatment plant was put into rapid construction...
