Dragon Ball starts, looking for love and traveling through the heavens!

The surface of the wandering planet is really extremely cold. Except for Hao Ren, Yzaks, and Bekai's family of four, everyone else has to wear a special life collar to adapt to such a harsh climate and environment.

"In such a harsh environment, are mom and dad okay?" Nangong Wuyue began to feel sad again.

"Sirens can survive as long as there is water. Although it is very cold here, there is still water, so mom should be fine, but dad is probably miserable!" Nangong Sanba just closed the life collar. After only one second, he felt suffocated and severely hypothermic.

"The environment here makes it impossible for me to maintain my human form!" Yzaks turned back into his true form of the Flame Demon.

If the temperature in the environment where the sirens are located is too low, they will put themselves into a state similar to hibernation, and the demon hunters also have some trump cards that can barely save their lives in extreme environments, so it is highly likely that the parents of the Nangong brothers and sisters should still be alive!

"Everyone, don't rush to analyze, let's go in the direction of those planetary engines first!" Kaisha interrupted the heated discussion.

In this way, everyone moved towards the direction of the interstellar engines of the wandering planets, but the speed of their movement showed a very obvious difference:

Beike and the other two took the lead and walked in the front, followed by the Beiyu sisters, followed by the calm Yzaks, and then after a distance of several dozen meters, it was the barely calm Hao Ren and Vivian, and after another distance of several dozen meters, it was Liu Lili who was a little unable to walk, and finally after a distance of more than 100 meters, it was the Nangong brothers and sisters who had difficulty walking.

After the group moved forward for about seven or eight kilometers, Hao Ren finally remembered that there was a Beidouxing car in his accompanying space that could adapt to any environment.

Next, Hao Ren drove the Beidouxing car, which had the most complete functions except that it could not transform into an Autobot, on the surface of the wandering planet. Through the car window, everyone saw one after another huge steel buildings full of historical vicissitudes, standing on the desolate and strange land.

Presumably, before entering the doomsday, this planet had already developed into a metal-based architectural style. Stone and wooden houses have become a thing of the past. Such a civilization should have entered the space age!

The rocket device that pushed the planet forward was like an erupting active volcano. The black energy transmission pipelines, with each "active volcano" as the center, were spread all over the vast planetary surface. They were like human blood vessels, providing a steady stream of power for the planetary engine.

The surface of the planet was already so desolate, and there were no stars in the starry sky as an energy source, but these planetary engines could still continue to work, indicating that their energy source must be underground.

After arriving in front of one of the planetary engines, Hao Ren and his team were looking for facilities such as tunnels that could lead to the underground.

The underground passage that Hao Ren and his team could not find was simply nowhere to hide in the eyes of Beikai's family. The engine located in the middle of many planetary engines had a door and passage that could lead to the underground world at its "feet".

Just as Kai Yu was about to use the half-broken Eye of Insight to open the door to the underground world, the outer shell lights of many engines on the surface of the planet actually lit up by themselves.

"Human traces have been found, and we are contacting the main brain... The main brain has authorized the dispatch of the third transport convoy to welcome humans to move into the underground city!" Then, an electronic voice prompt sounded into the ears of Hao Ren and his team.

After a moment, a taxi-like vehicle arrived in front of Hao Ren and his group in an orderly manner. There were ten people in their group, and then the so-called mastermind sent ten cars, and these ten cars were floating cars without wheels.

Each car had only one seat, so Hao Ren and his group had to board one car each, and according to the size of the passengers, the car carrying Yzaks was wider than the other nine cars.

"Disinfection procedures are being carried out, and harmful elements are being detected. Please wait..." After everyone boarded the car, it did not start immediately, but first started a series of inspections for the passengers."The test is complete. The physical values ​​are normal and the spiritual world is not polluted... It meets the requirements of the main brain. Start the vehicle and head to the underground city. I wish you all a pleasant journey!" After testing the physical condition of Hao Ren and his party, ten vehicles set off in unison to the underground.

After passing through a tunnel leading to the underground world, Hao Ren and his party came to the underground city of the planet. Here, they even imitated the appearance of the starry sky, built an artificial sky and an artificial dome, so that it can simulate the scene of day and night, and even the alternation of four seasons.

The scale of the entire underground city is much larger than many metropolises on Earth. The people on this planet seem to have hollowed out the core of the planet before finally building a city of this scale. The underground city is like the steel ruins on the surface. They are all buildings made of various metals, but it seems to be empty here.

"Are my parents really here?" Nangong Wuyue looked at the brightly lit underground city, and she was always infinitely melancholy in her heart, because she was afraid that everyone had worked in vain again.

"They should be here! According to the memory of the King of Wraiths, when he brought your parents to this planet, there was still the burned sun in his field of vision, which means that at that time, the wandering planet was still in place. It should be the arrival of your parents that started the planetary engine!" Hao Ren said a set of theoretical knowledge.

In short, if there is no one on the planet, the planetary engine will not start. When there are people on the planet, the engine will start. This feels like some kind of intelligent program, which is set to take humans to escape immediately after discovering humans.

While Hao Ren and others were still having a heated discussion, Bei Kai's family had already adapted to the operating rules of this underground city. When humans want to go out, they only need to stand under a certain road sign without saying anything. After just a few seconds, an unmanned car will come, and the style and size of the car will be different according to your size and gender.

After getting in the car, it is also voice controlled. Just say where you want to go, and the car will take you anywhere in the city, and you don't have to spend a penny. In this way, the Bei Yu sisters each took a car and drove straight to the store selling snacks.

It's called selling, but it's actually a literal zero-yuan purchase, because any product in the mall can be freely selected by you. When you take a product, a robot with four small wheels at the bottom will come over to replenish the product that has been taken away.

It's just that these replenishment robots are numbly executing orders, because no matter what you say to them, they will not give any answer.

For the food with a shelf life in the mall, once it is over the shelf life, a replenishment robot will come to take it away in just one minute, and then replenish it with fresh products.

This is the first time that the Beiyu sisters have filled their stomachs by eating snacks, and they both ate the top snacks. The taste of the snacks here is basically no different from the snacks on Earth.

The overall operation program of the underground city is also very mechanized. After the simulated 10 o'clock in the evening, a full-time robot will come outside and "invite" the humans who are still wandering outside back to their respective houses.

Next, there will be a butler robot urging you to go to bed early... It must be after 8 o'clock the next morning before the butler robot allows humans to go out.

And every morning for breakfast, there are dedicated cooking robots to prepare breakfast for humans. No matter what type of food you want to eat, you just need to use voice commands!
