Daddy also had a good harvest today, recovering more than a dozen waste energy boxes from outside, as well as some other messy waste products, and piling up a lot in the corner of the small courtyard.

"Does this still work?"

Anan came over and picked up an energy box and looked at it, "This is much older than the energy box in our house, you can see that it has rusted like this!" ”

"It's okay if you can't use it,"

Dad was afraid that Ye Huang would be disappointed, so he hurriedly said, "Anyway, it's all waste, and if you can't do it, you won't lose anything!" ”

Ye Huang smiled and said, "How do you know if you don't try?" ”

"Ah, this is a mineral crystal energy box!"

At this time, Anan suddenly snorted softly, "Fourth-order energy box!" ”

"Fourth-order?"

Ye Huang's eyes flashed.

Interstellar habits are graded, and civil energy boxes are generally divided into nine orders, with the ninth order being the highest, and the first and second orders are called low-level energy boxes.

Like Dad's small courtyard, it used to be the cheapest first-order energy box.

This kind of fourth-order energy box can generally support the electricity consumption of a villa for three months, including the overall electricity consumption of various domestic electricity!

"Wow, Daddy, are you going to collect scrap in the main city?"

Anan was surprised, "No one here can afford to use a fourth-order energy box!" ”

"It's the auxiliary city,"

Dad hurriedly said, "It took me fifty star coins to recover, it's too old, but even if it can't be used, I can sell it to the scrapyard for seventy or eighty star coins, no loss!" ”

As he spoke, he rummaged through the pile of waste again, took out a round mound-like thing, and said, "I recycled it with this one, and this one also used more than fifty star coins!" ”

"Smart housekeeper?"

Mu Hong and the others shouted excitedly on the side.

Ye Huang put down the old fourth-order energy box in his hand and came over to take a look at it curiously.

Intelligent housekeepers are interstellar intelligent robots, and civilian intelligent robots are generally called little housekeepers, which can handle a family's housework according to certain procedures.

To put it bluntly, it is a robot nanny, which is very practical, and generally medium-sized families in the interstellar world will be equipped with an intelligent housekeeper.

"Old model,"

Dad smiled, "At present, this one has been eliminated from the market, it is too energy-consuming, and the family bought a new one, so they sold this for scrap, saying that as long as the energy box is carded, it can still be used." ”

"This kind of butler must use at least a third-order energy box,"

Anan looked at the model, pouted and said, "A third-order energy box is stuck in, I'm afraid it won't take a month to run out of energy, and I can't afford it!" ”

This kind of outdated smart housekeeper with high consumption and low configuration, the rich don't like it, the poor can't afford it, and it can only be disposed of as a waste product!

"Who says you can't afford it?"

Ye Huang picked up the fourth-order energy box just now and shook it, "Wait!" ”

She was curious.

After all, the scientific and technological level of country Z is not as developed as interstellar, and she only used sweeping robots when she was in country Z, and she really wants to see the level of interstellar robots.

"Bear it, you!"

Anan was a little skeptical, "This is not a low-level energy box, it's not something that you can stimulate a little energy by just scratching it!" ”

Ye Huang raised his eyebrows: "A little energy? ”

Anan immediately closed his mouth.

The energy box that Ye Huang got last night, but it has been used until now!

Yesterday and today, everyone took a shower more than once, not to mention, her broken airship was also charged a lot, and there was no warning of insufficient energy in the energy box!

Ye Huang smiled, returned to the room with the fourth-order energy box, found out the tools and began to carve runes on the energy box.

Anan and Mu Hong surrounded them curiously.
