The world is shocked!You call this a small desert island

Soon, Lin Feng returned home.

Once the door is closed, quickly open the task panel.

[Task: Garbage disposal]

[Task introduction]: There are many islands in the Mirage Islands, far away from the mainland, and the natural ecological environment of the islands is relatively fragile.

And because of the small land area, it is difficult to carry out large-scale centralized treatment of garbage on islands like land.

With continuous development, garbage must increase significantly.

Cleaning up the garbage has reached the point of no delay.

Please master solve this problem as soon as possible.

[Mission Objective]: Establish an all-around clean garbage disposal station (buildings or blueprints can be purchased in the Charm Store)

[Task Reward]: Depends on the completion time (to be collected)

"Get the reward!" Lin Feng said decisively.

[Ding, the house renovation mission package has been successfully opened, and the rewards are as follows:]

1. Construction - island sewage treatment system

2. Special - hot spring agricultural technology

3. Special - hot spring eye*1
very simple.

The simplicity of this award can be felt from the name.

Let alone the first two rewards!

The third reward is a spring eye, which is a bit of a show.

If it appeared some time earlier, maybe I would be happy.

But recently, more than ten springs have been discovered in the entire Mirage Island.

In this case, it's meaningless to reward another spring eye!
Lin Feng revealed an expression that was as expected.

"It doesn't look like it's useless, it's more or less useful."

Obviously, compared with the 'renovation of residential buildings', this award is much, much shabby.

Even compared with the task of 'guaranteeing power', it is much worse.

However, it is also psychologically prepared.

Lin Feng did not feel any disturbance in his heart.

Instead, quickly open the first reward.

【Name】: Island drainage system
【Type】：Building
【Status】: not used

【Introduction】: Provide drainage system for an island.Including sewage treatment stations, sewage pipes, etc.
Soon, Lin Feng introduced him to him.

Muttering to himself: "Sure enough, it's as shabby as I imagined, but it's more or less useful, saving millions of charm points."

Basically, this reward is to help an island build a sewage treatment system.

After receiving the reward, the sewage pipes of the existing buildings will be connected to the sewage treatment plant.

I have to admit that this sewage treatment plant is also a black technology.

All kinds of sewage on the island will be completely purified to be harmless.

As for the various impurities contained in it, they will be pooled together.

It can be transported to the waste treatment plant for secondary treatment.

It can also be regarded as a very practical black technology.

Thinking of this, Lin Feng set his sights on the second reward.

The use of hot spring water for agriculture is nothing new.

Lin Feng had already studied this point when he dug the hot spring.

In the Tang Dynasty, there was a precedent for using hot springs to cultivate vegetables.

Wang Jianzai, a poet of the Tang Dynasty, said in his poem "Early Spring in Front of the Palace": "There are [-] high-rise buildings with wine mantles, and flowers in front of the Yangliu Temple in front of the palace. The inner garden is allotted with warm water, and melons have been planted in mid-February."

It can be seen from this that the hot spring agricultural technology has been quite exquisite.

After all, more than 1200 years ago, our ancestors were able to use hot springs in Chang'an to grow melons and fruits for the court in the cold winter.

What he was curious about was the difference between the technology provided by the system.

【Name】: Hot spring agricultural technology

【Type】：Building
【Status】: not used

[Introduction]: Using this technical solution, hot springs can be effectively used, and crops can be grown throughout the year and tropical aquaculture can be effectively realized.
It took Lin Feng a lot of time to finish the introduction.

But in fact, this technology has only a few characteristics:

1. Use hot springs to build natural greenhouses to achieve off-season planting.

2. Use hot spring water for direct aquaculture to realize tropical fish farming in winter.

3. The ocean hot spring water can be desalinated and then used for irrigation and other operations.

4. The hot spring water contains a lot of minerals that are beneficial to animals, which can greatly improve the individual immunity of animals and aquatic products, and at the same time, eliminate most parasites.

5. It can speed up the growth rate, and at the same time ensure the plumpness of the meat, which is also of great benefit to the eater.

"It's interesting, but it's a pity that it doesn't have much impact on Mirage Island."

Lin Feng shook his head helplessly: "The hot springs for the last reward should be placed on Dangkang Island. It can be regarded as an added gimmick."

For this reward, Lin Feng really didn't feel very good.

In his plan for Mirage Island, agriculture accounted for a very small proportion.

After all, in the absence of land resources, no matter how good the development is, the potential is very limited.

Given the current situation of Mirage Island, it is naturally the best choice to put the new hot springs on Dangkang Island.

After all, this thing still has some propulsion effect on livestock like pigs.

As for other types of technology, we will see the situation in the future.

When Lin Feng checked the information, Han Han posted a Weibo!
