Chapter 349 Reaching the Surface
There is no way. Although Han Ziang is already a grandfather, he still has entertainment needs. Therefore, the virtual reality game Oasis naturally meets Han Ziang's entertainment needs.

Early the next morning, Han Duoer excitedly came to the school with the equipment given by Liu Qi, and then changed into winter clothes under the guidance of the teachers.

Of course, as the leader of this team, Han Duoer's class teacher also put on winter clothes. After putting on a helmet, the class teacher said to the group of junior high school students who were already wearing winter clothes:
"Students, please remember, after putting on your cold-proof helmet, your voice will be transmitted via wireless radio. Press once for in-car synchronization, press twice for local broadcast, and press three times for private frequency!"

After the head teacher simply taught the students the basic functions of winter clothing, he led the students to the underground city's ground elevator.

Since they were special cases and belonged to the third-year junior high school students who were going to visit the surface, they naturally did not need security checks. The teachers took the students directly through the security check and entered the elevator.

However, after entering the elevator, Handuoer's head teacher still pressed the communicator next to the helmet and said to the students:
"We are now entering an elevator that goes directly to the surface. We are now five kilometers away from the surface, so it will take fifteen minutes to take the elevator. The reason why we dug the underground city so deep, in addition to being able to resist meteorites, the most important reason is to use geothermal heat to keep warm!"

That's right. If we don't build an underground city but build it on the surface, the temperature required for heating and insulation will be an extremely huge amount of energy. However, it will be different if we build the city underground.

You should know that the core temperature of the blue star is as high as more than 6,000 degrees. Although it is nothing compared to the core temperature of the sun, it can at least ensure that the deeper you dig, the hotter it will be.

Ten minutes passed in the blink of an eye. As the elevator door opened, a biting cold wind blew into the elevator.

As a result, the comfortable temperature of 18 degrees on the thermometer suddenly dropped to minus 82 degrees. The temperature on the surface and the underground city differed by 100 degrees.

Fortunately, although it looked very cold, the winter clothes were still very comfortable, so Han Duoer's head teacher walked out of the elevator first in the cold wind, and the rest of the students naturally followed suit when they saw the teacher had walked out.

After the class teacher left the elevator, he led the students to look for car number 373.

Soon, Han Ziang was seen waiting next to car number 373.

At this time, Han Ziang's original No. 373 mining truck had transformed into a sightseeing vehicle towing a sightseeing carriage.

As for the truck bed originally used to load ore, it was naturally left in the mining truck maintenance workshop. This is the advantage of the trailer truck. It can be immediately transformed into any trailer vehicle whenever needed.

For example, if you need to transport large items, such as construction vehicles, you can tow a flatbed truck to turn it into a trailer flatbed truck.

However, just when the head teacher and Han Ziang were confirming the handover, all the students in Class 8 of Grade 9 where Han Duoer was located were looking up in a daze at the planetary engine jet nozzle more than ten thousand meters high in the distance!

There is no way to say it, it is so spectacular. It is hard to imagine that human beings have such power to build more than 12,000 planetary engines that are taller than Mount Everest.

However, the head teacher looked at the students who were in a daze and reminded them:
"Okay, students, you have to get in the car now, otherwise the battery of the winter clothes will run out, and if that happens we will be in danger!"

When Han Ziang heard what the class teacher said, he cooperated and opened the stair door of the sightseeing car, allowing the students to enter one by one.

However, Han Duoer never entered and didn't even join the queue. So when only Han Ziang and the class teacher were left outside the car, Han Duoer was needed.

The head teacher immediately shouted to Han Duoer:
"Han Duoer, why don't you come over now? If you stay outside for too long, the battery of your winter clothes will be used up!"

However, Han Duoer shook her head and said:
"Teacher, I want to sit in the front of the car with my grandpa. The sightseeing car is too crowded!"

"Your grandpa?"

After hearing what Han Duoer said, the head teacher couldn't help but look back at the driver standing next to him, and asked in confusion: "You said you wanted to sit in the front of the car with your grandpa, could it be that your grandpa is the driver?"

Just as Han Duoer was about to speak, Han Ziang said to the head teacher with a smile on his face:

"Yes, class teacher, I am Han Duoer's grandfather. I even attended Han Duoer's parents' meeting!"

The head teacher also remembered it, so he looked at Han Duoer, then at Han Ziang, and finally agreed to Han Duoer's request.

There was no other way. After all, they still had to rely on Han Ziang to drive them to visit the planetary engine!

So, amid Han Duoer's cheers, he followed Han Ziang into the driver's cab of the car.

The driver's cab at the front of the train is actually not small. After all, although the sightseeing car towed behind the train is bigger, don't forget that there are more than 50 students sitting in the sightseeing car. Therefore, relatively speaking, the driver's cab at the front of the train is naturally much more comfortable than the car at the back.

Of course, when Han Duoer entered the cab of Han Ziang's No. 373 truck, she was also shocked. After all, the vehicles inside the underground city are simply incomparable to the mining trucks on the surface!

Of course, what shocked Han Duoer the most was that there was actually an independent small toilet in the cab of the mining truck to solve the driver's three urgent problems. If you ignore the properties of the front of the car, there is no problem in treating the front of the mining truck as a motorhome.

Of course, there is actually a small bathroom in the sightseeing car towed behind the front of the car. After all, it is so cold in the weather, and you will probably freeze to death if you get off the car to take care of personal physiological problems!

Therefore, unless you can't hold it anymore, you won't solve physiological problems outdoors in temperatures of minus 80 degrees Celsius.

However, while Han Ziang was taking Han Duoer and a group of students to visit the planetary engine, Liu Peiqiang was also carrying out his final work in space 100,000 miles away.

Because as long as the Blue Planet successfully escapes from the gravity of Jupiter, it will be time for Liu Peiqiang to retire.

At this time, Liu Peiqiang and his partner Makarov were checking the normal operation of the navigator space station.

At this time, Liu Peiqiang was carrying out his normal work with Makarov and asked Makarov:

"Are we going to enter Jupiter's orbit today?"

Makarov replied:

"Yes! All the requirements for emergency plan number three have been prepared!"

However, after hearing Makarov's words, Liu Peiqiang sighed:
“I always feel uneasy!”

However, Makarov said helplessly:

"There's no other way. Blue Star must rely on Jupiter's gravity to fly out of the solar system, so we have to take this risk! God will bless us! As long as we get through this hurdle, we can go home!"

In response to Makarov's words, Liu Peiqiang just smiled and didn't say anything else!
What can we do? Makarov has already said that escaping the solar system with the help of Jupiter's gravity is something that must be done, so there is no choice.
