When he brought the underground plant kingdom from the surface to Wedel, Haisong was in a coma, unaware of his journey through the center of the earth.

By the time he left, he was finally able to experience this thrilling and fantastical long journey.

After bidding farewell to Professor Li Zhengsong that night, he walked around the primeval forest, and returned to the villa with a heavy heart with the purple apricot leaves left as a souvenir. The owner of the villa is gone, and in a few hours, the only one left here will be the robot cook.

Before leaving, Aunt Lucy meticulously dressed Hai Ge. It was a beautiful black backpack with food and water, a change of clothes, and simple toiletries. Of course, the most important thing is the hard drive left by Weddle and the box containing the pro-firebug, which are hidden in the mezzanine and cannot be easily discovered.

In the past, when running around with the Wolf's Den Circus, Hai Ge was only qualified to "pack up" for the herd, and he and Benlong were like two vehicles with the car, and the tools did not need to carry luggage.

When he escaped from the wolf's den, there was no such thing as "luggage", the most important thing at that time was two legs, as long as he could run forward, he could not stop, and what he needed, whether it was food or use, could only be found from the garbage heap, and he had nothing of value except for the wolf's head dagger.

Now, like an ordinary person in the city, he has to carry a backpack to travel! It felt strange and new, he was a little unaccustomed to it, but he liked it very much, and in short, he was quite conflicted.

Standing on the edge of the bed, watching Aunt Lucy busy going around, he wanted to do something but couldn't intervene, so he had to be in a daze. Aunt Lucy packed up and handed over the backpack with a smile, and the only thing he could do was accept it in silence.

The backpack was heavy in her hand, looking at the dark and round face of the fat cook, Hai Ge thought that when she was leaving, she should say a few words of thanks to her. Of course, not only to thank her for the delicious meals she cooked, but also to take care of herself like a mother.

He reached out to squeeze Aunt Lucy's thick fat hand, but changed his mind halfway through and hugged her tightly with open arms.

"Mom~" Hai Ge called quietly, but his throat was choked so badly that he didn't say anything.

Aunt Lucy reminded him that in addition to the necessary items, there was a communicator in his backpack, which Mr. Weddle had repeatedly instructed him to keep before leaving.

"A small communicator, so important?" Haige was curious, so he took it out and looked at it.

The shape of the communicator is quite chic, short and chubby like an owl. The two pointed ears are erected, and the antennas are presumably hidden inside. There are screens on both sides of the front, and when you light up the screen, a button panel will appear.

Hai Ge couldn't figure out why he had to set the communicator on two sides after watching it for a long time. Isn't it just for phone calls? One side is enough, right?

When he reluctantly said goodbye to the small villa, boarded the AI-controlled Doji aircraft, and flew to the port on the coast of the Earth, Li Zhengsong called, and he understood that the two sides of the communicator do have different purposes.

The front is dedicated to making calls, and there are three communication channels to choose from: underground, above-ground, and cosmic areas. The Redeeming Light's communications network has fully covered all three places, but calls must be strictly separated to prevent signal leakage and eavesdropping.

The effect of the reverse screen is extremely powerful, and it can be said that all the activities that Haisong will carry out in the future, including controlling the launch and berthing of the Huoyiren, and the transformation of the form between the yacht and the spaceship, can be completed through it.

It turned out that this was a multi-functional communicator, which had many more uses than "making calls", and Hai Ge shook his hand slightly, thinking that if it was accidentally lost, it would be a big trouble.

Li Zhengsong talked to him remotely, instructed him on which Earth-to-Earth variable star spacecraft to board, and showed him a navigation map from the center of the earth to the ground, and how to get to the train station after reaching the ground.

The entrance to the old garage in the western suburbs of Xijin City has been blocked, and Haige can no longer get out of there, in fact, four of the five underground entrances that Wedel has dug with the U-star drill have had to be abandoned, and the only one left is in western China. In that place, there are constant sandstorms all year round, and thousands of grottoes are carved on the high mountains adjacent to the desert, and the Buddha statues that have been sharpened beyond recognition by time are erected in the grottoes, which is an excellent hiding place.

Wedel does everything he can, and the same goes for the underpasses. The Western Desert Passage was a backup, and he never mentioned it to anyone, so even the people in the Light of Salvation thought that there were only four paths from the underground to the surface. After Li Zhongyuan defected and died in the molten iron and nickel, Weidel pointed out the fifth passage to Li Zhengsong, from whom he himself had gone a few days earlier, before leaving.

The underground plant kingdom's harbor, located behind the factory of the Light of Salvation, occupies half of the vast offshore platform.

Viewed from the air, the Ground Harbor is a huge seashell, buckled upside down on the platform, and you can faintly see the neatly arranged spaceships through the transparent glass canopy.

According to Li Zhengsong, most of them are space engineering spacecraft that will go to the solar system to build triangular orbits, and the number is as high as 30,000, and the number is still increasing. The rest are small ships that resemble Doji Vehicles, which can be used both to navigate the Underground Plant Kingdom and to serve as supply ships in space. The largest Doji vehicle can seat ten people and has a carrying capacity of twenty tons.

Looking at the large-scale ground port, Haige always felt that something was missing here, and during the Doji landing, he suddenly remembered that what was missing was a combat spaceship.

Li Zhengsong explained: "Yes, there has never been a single combat spaceship in the underground plant kingdom's underground harbor, and this is Wedel's decision. He is a scientist who has vowed that he will not be involved in war in his life, so there will be no fighter jets in the type of spaceship he develops. ”

Haige had never seen Weddle piloting the U-Star variable spaceship to Earth, which disintegrated when it landed in the Australian desert. However, Li Zhengsong said that it was the predecessor of the Earth Voyage Variable Star spacecraft, and according to the original spacecraft drawings, Wedell improved the temperature resistance of the hull and the penetration of hard rock formations, and subtracted the function of the cargo compartment, and transferred the power of the special supply compartment to the main engine, thus greatly increasing the speed of the spacecraft.

Although the new variable star spacecraft still has a limited speed, it is quite close to the Blue Whale 700, which has a speed of 350 kilometers per second. Sitting in the spacious cockpit, Haige's heart was beating suddenly, and he felt that his once pale and colorless life was about to open a new chapter. The new pages are full of challenges and hopes, there must be adventures between the lines, but there will also be gains, in short, from this moment on, he has taken the first step steadily in the journey to save the planet.
