As for the depth of deepening the small lake, you can't do it at all.

Luo Yu learned through the big octopus that the bottom of the lake also exists like an air wall, which cannot be sneaked to the deepest.

It seems to be three options, in fact there is only one way in front of Luo Yu's eyes: the dam -making dam.

In fact, there is another advantage of building dams. A simple circle around the small lake can effectively reduce the loss of soil and soil, and it will not lead to the reduction of the fertility of the territory as a whole.

Nothing to say, make it.

Click on the architectural page, or the wall interface, Luo Yu intends to build a 20 -centimeter -high mini wall.

This is water blocking is not a blocking person. It is almost 20 cm, just stack it up.

When choosing the material, he was used together with stone bricks and iron ore.

Click to build, the mini wall began to spread along the shore of the Lake, but a moment was surrounded by a lap.

Don't look at the low cost of the mini wall, but it is made! This time, the 3W stone brick is 1W iron ore.

The consumption of this stone brick is really fast.

Fortunately, the small water spots are completed, so don't worry about the water level overflowing.

Take a look at the base score. The mini dam and the previous beautiful water tower gave another 1,000 points. Now the overall score has reached 21500.

"Do you want to build defense facilities?"

Luo Yu's eyes instinctively looked at the south of the territory.

In the wind and rain, the simple fortress stood up, and the automatic crossbow was lying quietly at the top of the stone pillar, ready to launch.

"Hey? The area of ​​the territory had become larger before, and the edge of the territory was beyond the coverage of the crossbow."

Luo Yu frowned slightly, and the area of ​​the territory will continue to grow. In order to consolidate the defense on the south, the crossbow arrow needs to be continuously extended. The cost of the crossbow is still a bit expensive.

He always feels that it is not a way to go on.

"Master, eat."

Xiao Jin walked on the balcony to remind Luo Yu that breakfast is egg milk and tomatoes. This does not require cooking, so breakfast is now prepared by Xiao Jin.

Luo Yu took back his thoughts, gently touched her head, and washed to eat.

In the morning, the rain did not decline, but Luo Yu received a reminder: [Your powerful thermal energy absorption station is in a state of not working]

Hurry up to the roof to see, good guy, this stone bowl is full of water, and there is a ghost if you can work.

Luo Yuhaha smiled, setting the stone bowl to the diagonal angle 60 ° like this, and the water inside flowed out most of the water, which did not affect the thermal supply.

Look at the power, thermal energy output: 1000

The power of the thermal energy collecting board next to it is only 100, and the effect of thermal function of the heat on the rainy days is much lower. This will stop the work of some firepower pumps.

This reminded Luo Yu.

How much water is needed every day is good. Now the wind is strong and there may be no problems, but when the weather is not windy, the weather is in a relatively cold situation, then the territory may fall into a state of water discontinue.

This is this thermal absorption device. The weather is hot, the power exceeds the standard, and there is no output when the weather is cold.

As soon as the weather was cold, the problem appeared again, and I had to find a way to solve it.

After opening the thermal energy technology, after looking for a moment, Luo Yu's eyes lighted up and found a solution.

[Thermal energy storage box: design drawing of thermal energy storage box*1, copper ore*10000, gold*5000, silver*100000]

This thing is slightly cheaper than the thunderbolt collection box, but it is also expensive.

But there is no way. The thermal energy storage box is a necessary device for automated bases, and it is also one of the front conditions for unlocking the thermal weapon.

Take a look at the mineral resources of the territory, copper ore 20,000, gold 7000, I have to say that the Golden Scorpion King is still awesome. Find a brick back every time.

I don't think so much gold.

Now there is a design drawing. Luo Yu searched at the auction house and did not find it.

He tried to shout in the world.

Human clan (anonymous): "The design drawing of the heat -collecting energy storage box, some costs."

It was originally shouting with the mentality of trying it. As a result, some people really sent the trading box.

Hei Shui (anonymous): "Are you receiving the design drawing? I have one, what are you going to change?"

To put it, put the design drawing on the transaction interface, the genuine price.

Luo Yu's eyes showed a hint of joy: "Of course you use silver to change, how much money, you open the price."

Hei Shui: "I don't want silver, I have element."

"3000 vegetarian food, I will trade the design drawing to you, buddy, you have made this wave of what you think of."

"Make it?"

Luo Yu laughed at the reply: "The price of vegetarian food will rise immediately, no, now it has soared. I am afraid that 3,000 vegetarian food can only be sold for 30w silver. Do you think of me?"

"Besides, do you think how many people can come up with such a vegetarian?"

Black Aquarius: "This ... is the reason you say, then what kind of trading method do you say!"

Luo Yu: "In this way, there are some inventory on my side. I give you 1500 vegetarian food. This is all of me at home, and then give you 5W silver, only so much."

Hei Shui: "Do you really have 1500 vegetarian food?"

Luo Yu did not talk nonsense, and put 1500 vegetarian food directly: "How do you, all kinds of varieties have vitamins and complete transactions, the heavenly world opens the secondary transactions of food. You should know what the price of these vegetarian foods can sell?

"

"If you can process it again ... You are a smart person, you should understand."

After the Black Aquarius was silent, I still replied: "Okay! Look at your variety such a complete part, I will trade with you!"

"But I want to remind you that you have traded all the vegetarian food to me and do it yourself!"

[Successful transaction, you get the design of the thermal energy storage box]

With!

Luo Yu smiled, and this time the picture was still very smooth. He was going to build a storage box.

And once the design drawing is used, there is no need to collect the design drawings after using the design drawing. This sale is still very profitable.

Click OK, the light in front of you flickered, and a square red box of one person appeared.

[Thermal energy storage box: stored 50,000 units of thermal energy, 1%of the daily escape thermal energy, placed in a closed space can greatly slow down thermal energy escape]
