The first generation of water droplet capacity storage, which can hold 100,000 cubic meters of water resources at a time, was also used by Xu Ran at the beginning, and he worked as a water delivery worker for a period of time.

The second-generation type can reach more than one million cubic meters at a time.

By the third generation, it had reached a threshold of 5 million cubic to 10 million cubic meters.

Today, the fourth generation has completely broken through the threshold of 10 million cubic meters, and the improved version can store up to 90 million cubic meters of seawater resources, and is still being researched and upgraded in units of more than 100 million.

It can also be seen through the second-generation research and development of the water droplet storage that the level of scientific and technological strength of the artificial intelligence experimental center is gradually increasing.

Just like in the past, there was no such type of flying robot as the fragmented city, but now it has been able to develop and produce flying robots, which is the result of the continuous upgrading of the scientific and technological strength of the artificial intelligence research center.

In addition, there is also the research of black technology, and there are already a lot of black technologies that have been researched and put into application.

For example, the improved third-generation aircraft in Xu Ran's hangar in the debris city has evolved towards the prototype of the space shuttle.

However, even if it is the second generation of the backward elimination of the fragmented city, that is, the last time Xu Ran carried out the helicopter piloting experience, the kind of comprehensive improvement of the second wave of piloting, if it is put on the earth, it also belongs to the high-end black science and technology achievements.

This second-generation aircraft, Xu Ran plans to put it in the underground base of Tridoran Island to use.

As for the first generation, there is also a helicopter with a traditional and ancient mode of operation, both in appearance and operation method, it is similar to the helicopter on the earth, but he has improved and upgraded the energy system, and no longer uses outdated things such as aviation kerosene, but uses a purple light energy pool.

Therefore, Xu Ran came this time to bring back this original helicopter and put it in the hangar in his manor for daily use.

And even if the secret of the purple energy pool as a driving energy source is exposed, it will not cause much impact, and it is a big deal to use the shell of the super battery as a camouflage.

Even if it's the original mod, it's a good thing for Earth, and if it's a collector's item in a fragmented city, it's a bit wasteful.

So this time, after Xu Ran sent the water resources in, he came to the hangar again.

There is another plane in the hangar, which is the third generation of samples created by the new research, he has completely departed from the category of ordinary aircraft, and has some prototypes of space planes, and the size is several times larger than the first two, like a house.

Xu Ran entered the interior of the third-generation aircraft and took a look, it can be said that Xu Ran is completely unfamiliar with the design and structure inside, as well as those functional facilities.

After all, this is a prototype sample made after the combination of black technology and current technology, although it can also be lifted into the air, and the performance and speed are hundreds of times stronger than the previous two generations.

But Xu Ran doesn't have much interest in experiencing it for the time being.

After all, this thing was already a little out of touch with the technology system he already knew, and he had to spend a lot of time learning again, and he didn't have that much time to learn about the technological creations on this earth that were impossible to expose at all.

Therefore, Xu Ran transferred a few robots over and asked the robots to unload the purple light energy pool used by the original modified helicopter to disguise the appearance of the super battery block.

The robot did the job with ease, was retrofitted in a very short time, and then reinstalled on the helicopter for another layer of protection.

After the final debugging was completed, Xu Ran asked the robot to paint the entire fuselage in black, and then began to package it as a whole.

After the packaging was completed, Xu Ran gave an order, and the artificial intelligence control system automatically called in an autonomous container truck.

This container truck is left over from the original fragmented city, but now all of them have been installed with intelligent terminals and intelligently modified, which is completely an information product controlled by artificial intelligence, and is completely a smart truck.

In fact, Xu Ran's cooperation with Liu Jingdong on Earth includes the project of this intelligent logistics truck and the provision of a supporting artificial intelligence management system.

After the smart truck drove over on its own, the robot loaded the packaged helicopter into the truck, and then the smart truck drove to the teleportation point as required to wait.

After finishing all this, Xu Ran went to the data center again.

The data center here is actually Xu Ran who has completed the exploration of the entire fragmented city, collecting all the remaining paper materials and books, as well as the relevant information stored in some electronic products, and storing them in a building.

It's just that the last time there was turmoil in the fragmented city, Xu Ran asked the robot to relocate all of them to the dungeon in order to prevent these information materials from being affected and destroyed.

Now the dungeon is also busy, and all the surviving human living facilities have been renovated, and now there is a large library that has been specially renovated, also called the resource center.

After going to the data center, there is a team of robots dedicated to these tasks, including retrieval, query, copying, archiving, ...... and all other related features.

Xu Ran entered the data center and was led by a robot to the data storage area related to film and television entertainment left behind by the Blue Star Civilization.

There are a lot of music CDs and DVDs collected here, and some of them are also available on memory.

The last time Xu Ran came in, he asked the robot to repair and read these discs, and provided the robot with a template of the script of the music and film and television works commonly used on the earth, and let the robot generate text scripts and music scores by reading and scanning all the music and film and television works left over from the Blue Star World.

The robot has already completed this work, and Xu Ran came over this time to prepare to take some back to Wei Zi's film and television company to use, so that they can develop smoothly.

After picking a few songs and a few TV and TV scripts suitable for Wei Zi to star in, Xu Ran copied them and saved them in a USB flash drive, which came out of the data center.

"Dear boss, wait a minute!"

However, after leaving the data center, An An quickly moved over with two robot assistants.

But An An's voice was so cute and glutinous, Xu Ran couldn't help but be a little puzzled, he remembered to change An An's voice control system's previous cute and coquettish voice to normal, how could this happen again?

However, this kind of voice is not the kind that gives people goosebumps, and it is comfortable to listen to, so Xu Ran didn't care about these small details, and asked, "What do you want to report to me?"

An An said: "Boss, the surface manor here has been completely rebuilt, and a staircase passage that can go directly to the dungeon has also been built there, and the underground manor villa where you live in this dungeon has been connected to one, do you want to visit it$article?"
