One night is not enough, and there are several nights in a row.

Lack of sleep at night and energy during the day went to school, so much so that her sister-in-law saw the clues.

What's even more embarrassing is that a "strawberry" was planted on his neck without knowing it.

Shame on the country of Java!

Xu Suizhu snorted angrily in his heart: Starting tonight, punish him for being pure and lacking desires for a week!

"No wonder, then you catch up on sleep, it's still early before dinner anyway. It's time for me to go back, too. ”

Wu Meili patted her trouser leg and got up and said.

On weekdays, I was afraid that someone would look for me after coming out for too long, so I didn't plan to sit longer. It's almost time to chat for a while.

Xu Suizhu knew that her cousin-in-law had a lot of things on hand, so she didn't keep her, so she packed a bag of pastries and snacks that she bought on Antique Street before she came, and asked her to take them with her.

"You're really, every time you come to buy food for everyone, you're about to raise the mouths of those people. Wu Meili feigned.

Xu Suizhu smiled and said: "Everyone has worked hard for me on the island for many years, and there are few opportunities to go out. ”

Wu Meili knew that she was polite. I really want to go out, it's not that I don't have no days off, at least one day off a week, but everyone is used to life on the island, and on the days off, I would rather stay in the dormitory to wash, wash, dry, sew and mend, chat, and occasionally tinker with some delicious food, and the interest in going out of the island is not great.

After sending off her cousin-in-law, Xu Suizhu released the octopus cleaning guard, cleaned upstairs and downstairs, took the engineering kit, and went to Qi Hui.

Qi Hui learned that the kit had been cashed out, and he hurriedly took it in his hand and said, "Not bad! It's a pity that when my uncle sent you the lottery system, the latest model has not yet come out, this should be the old model three years ago, it is a little clumsy, and it can't be upgraded. But compared to the ...... Ahem, the tools here are still a lot easier to use......"

Xu Suizhu glanced at him with a smile, how could she not hear the disgust in his words.

But who made him complain about the truth, with the current technology and productivity of the earth, even if it is given an extra hundred years, I am afraid it will not be able to catch up with the Federation system.

Qi Hui was afraid that she would be angry, because he had promised her a long time ago that he would not call the earth a star, touched his nose, rubbed against her, and said flatteringly: "Eldest sister, why did you come here today? Isn't it a holiday yet? Oh, are you here to see the progress of the art museum? Don't worry, I'll keep an eye on it for you, and by the way, I'll help you change a few small details to ensure that it is more practical......"

Xu Suizhu didn't expect this, but when he mentioned it, he wanted to go and see the art training base.

"Let's go, I'll go with you!" Qi Hui put away the toolkit and said earnestly.

"Aren't you busy?"

"I don't care if I'm busy for a while. Qi Hui excitedly took her to the art training base under construction, and introduced to her the architectural style and function modified by his hand as if pointing out the country, what voice-activated lights, rain collectors, and umbrellas were.

Xu Suizhu couldn't laugh a little: "You took out the baby from your upgrade device again? Didn't you say that you won't take it out casually anymore? When someone else comes to you to customize the exact same, how are you going to deal with others?"

Ordinary people are not worried, and they say that they will not take orders if it is a big deal, but what if someone is sent to the door?

"Ah!" Qi Hui waved his hand, "It's all transformed, and it's not impossible to use local materials, but the project is more complicated." I also want to ask you if you want to get these in the underwater city, forget about the rain collector and umbrella, it doesn't rain on the bottom of the sea, and the light has to be artificial, but the voice-activated lights can be considered, it's quite fun......"

Xu Suizhu couldn't help but hold his forehead: "Why don't you take it easy!"

I'm really worried that if he continues to be so high-profile, he will lose his freedom one day.

The country is relatively fine, but it is worried that the news of the undersea city will spread to foreign countries and attract the attention of some international organizations. Although he has a lot of weapons for self-preservation, after all, the enemy is in the dark and I am in the open. In case with the help of intoxicating drugs or something, Qi Hui was stunned and taken away, and then locked up in a hidden small black room so that he could invent all kinds of advanced products all the time, and he would cry without a place to cry.

Qi Hui shrunk his neck, probably recalling some of the potential dangers that Lu Chixiao had informed him: "The earth is so scared, I want to go back to my home planet." ”

“......”

I won't have to wait until now to get back.

Xu Suizhu pinched a sweat for him: "What if I can't find the shadowless tracker you said and never go back?"

"No!" Qi Hui was full of confidence, "I can't find the old one, my brother will launch a new one." It's nothing more than a few more days of waiting. ”

He still likes it here, the food, the beautiful scenery and the company of his eldest sister, so he doesn't want to go back right away.

"Eldest sister, don't you never look at the barrage area in the live broadcast room? Maybe the old man or brother has a message. It's a pity that my optical brain was damaged while traveling through the black hole, otherwise I would have started a live stream, it would have been fun......"

Xu Suizhu heard the words and twitched the corners of her mouth.

She wasn't really the eldest princess, but he didn't believe it when he explained it, insisting that it was because she had amnesia and didn't remember it, not that the system was bound to the wrong host. Because when it was originally customized, it was set that only the eldest princess would be recognized. Except for the eldest princess, no one can use it.

"Gong Gong!"

As he was talking, Lou Zhenghao, who had been following them from afar, answered the phone call and ran towards them quickly, "Something happened to the undersea city." ”

"What's the situation?"

Lou Zhenghao also felt incredible, but the person in charge of the No. 1 construction site did say this, "It is said that there are a group of turtles to make trouble, surrounding the seawater isolation layer, constantly making trouble and impacting, no matter how to drive it away, it is useless." The turtles are the size of boulders, and they are worried about whether the isolation layer will ......"

When Xu Suizhu heard "a turtle as big as a boulder", the first thing that appeared in his mind was the elderly turtle ancestor of the drama turtle, and he immediately said that he would go with Qi Hui to take a look.

Speaking of which, it was the first time she had come to the construction site of Undersea City.

The seawater barrier like the canopy of the sky will cover the entire underwater city in the future. With it, the workers who dig the foundation and build high-rise buildings at the bottom of the sea not only do not need to wear diving suits and diving headgear, but also breathe and move freely.

The freedom to breathe is due to the placement of several ventilation fans invented by Qi Hui, with two fan blades, one side inhaling carbon dioxide, and the other side blowing out a fresh breeze containing oxygen for people to breathe freely on the seabed.

But this is also temporary. After the foundation is dug up, it will be like laying a submarine cable, and a set of ventilation pipes like a fresh air system will be laid. That is the real core technology of the underwater city in addition to the "sky canopy". The "canopy" allowed the underwater city to be built, and the "ventilation tube" allowed people to live freely under the sea.
