Shock!The beginning is a land, and the crit strikes a miracle

Second: increase or deepen the overall volume of the small lake.

Third: build dams.

First of all, the first choice is safe, but according to the explanation of Tiandao World, draining the water in the small lake will cause the loss of aquatic resources.

There are big octopuses, big snakes and many turtles in the lake, and more will be raised in the future, all relying on aquatic resources, and Luo Yu does not allow loss.

The project of increasing the area of ​​the small lake is ridiculously large, and it will encroach on the land area.

Chapter 113 Dams, Thermal Energy Storage Tanks

As for deepening the depth of the small lake, it is simply impossible.

Luo Yu learned from the big octopus that there is an air wall at the bottom of the small lake, and it is impossible to dive to the deepest point.

Seemingly three options, there is actually only one way in front of Luo Yu: building dams.

Building a dam actually has another advantage. A simple circle around the small lake can effectively reduce soil erosion, and will not lead to a decrease in the overall land fertility of the territory.

Not to mention, build it.

Click on the building page, still on the fence interface, Luo Yu plans to build a 20 cm high mini fence.

This is to block water, not people, 20 cm is almost enough, if it is not enough, just stack it up.

When choosing materials, he used stone bricks and iron ore together, which can strengthen the mini-dams and prevent them from being washed away by waves.

Click to build, and the mini-wall began to spread along the shore of the small lake, but it surrounded the small lake in a moment.

Don't look at the low cost of mini fences, but there are so many of them!This time, the stone bricks that consumed another 3W were 1W iron ore.

The consumption of this stone brick is really fast.

Fortunately, the small water discharge dam has been completed, so there is no need to worry about the water level overflowing for the time being.

After looking at the base score, the mini dam and the beautiful water tower have increased by 1000 points, and now the overall score has reached 21500.

"Do you want to build defensive facilities?"

Luo Yu instinctively looked to the south of the territory.

In the wind and rain, the simple fortresses stood erect one by one, and the automatic crossbow arrows lay quietly on the top of the stone pillars, ready to be fired at any time.

"Huh? The area of ​​the territory became larger before, and the edge of the territory was beyond the coverage of the crossbow arrows."

Luo Yu frowned slightly. The area of ​​the territory will continue to grow, so in order to consolidate the defense in the south, it is necessary to continuously extend the crossbow. The cost of the crossbow is still a bit expensive.

He always felt that going on like this was not the way to go, and it seemed a bit stupid to build a bunker in such a defensive way.

"Master, it's time to eat."

Xiao Jin went to the balcony and reminded Luo Yu that breakfast is eggs, milk and tomatoes, which does not require cooking, so Xiao Jin will prepare breakfast now.

Luo Yu withdrew his thoughts, touched her head gently, and went to wash and eat.

In the morning, the rain did not show a downward trend, but Luo Yu received another reminder: [Your powerful heat absorption table is not working]

I hurried to the roof to have a look, good guy, this stone bowl is full of water, if you can work, you must be a ghost.

Luo Yu laughed, and placed the stone bowl at an oblique angle of 60°, so that most of the water in it flowed out, so as not to affect the heat supply.

Looked at the power, heat output: 1000

The power of the thermal energy collecting board next to it is only 100, and the thermal function efficiency is much lower in rainy days, which will stop some of the thermal water pumps from working.

This reminded Luo Yu.

How much water the territory needs every day is a good idea. Now that the wind is strong, there may be no problem. But when there is no wind and the weather is relatively cold, the territory may fall into a state of water shortage again.

This heat absorbing device is like this, the weather is hot, the power exceeds the standard, and there is no output in cold weather.

As soon as the weather cools down, the problem reappears, and we have to find a way to solve it.

Click on Thermal Energy Technology, and after searching for a while, Luo Yu's eyes lit up and he found a solution.

[Thermal Energy Storage Box: Thermal Energy Storage Box Design Drawing*1, Copper Ore*10000, Gold*5000, Silver*100000]

This thing is slightly cheaper than the Lightning Collection Box, but it's also quite expensive.

But there is no way, the thermal energy storage box is a necessary equipment for an automated base, and it is also one of the prerequisites for unlocking thermal weapons.

I took a look at the mineral resources in the territory. Copper mines cost 20000 and gold costs 7000. I didn't realize there was so much gold.

Now there is only one design drawing missing. Luo Yu searched the auction house, but couldn't find it.

He tried to shout out to the world.

Terran (anonymous): "Receive the design drawing of the thermal energy storage tank, and there will be a price."

I originally shouted with the mentality of giving it a try, but someone really sent a transaction box.

Heishuizu (anonymous): "You accept the blueprint, right? I have one. What do you plan to exchange for it?"

As he said that, he put the design drawing on the trading interface, it was genuine.

There was a gleam of joy in Luo Yu's eyes: "Of course it was exchanged for silver. How much is it, you ask for a price."

Black Aquarium: "I don't want silver, I want vegetarian food."

"For 3000 vegetarian food, I'll trade the blueprints to you, buddy, no matter how you look at it, it's a profit."

"made money?"

Luo Yu sneered and replied: "The price of vegetarian food will skyrocket soon, no, it has already skyrocketed now, I'm afraid that 3000 vegetarian food can be sold for 30W silver, do you think I'm being taken advantage of?"

"Besides, at this juncture, how many people do you think can come up with such vegetarian food?"

Blackwater Tribe: "This...you are right, so what kind of trading method are you talking about!"

Luo Yu: "Well, it just so happens that I also have some stocks here. I will give you 1500 vegetarian food, which is all my belongings, and then I will give you 5 silver, and I can only pay so much."

Black Aquarium: "Do you really have 1500 vegetarian food?"

Luo Yu didn't talk nonsense, and directly put the 1500 vegetarian food on it: "How about buddy, all kinds of vitamins are complete, Tiandao World has opened the secondary trading of food, you should know what price this batch of vegetarian food can sell, right? "

"If you can reprocess it...you are a smart person, you should understand."

After being silent for a while, the Heishui tribe still replied: "Okay! Seeing that you have such a complete variety, I will trade with you!"
