"Jump down." Li Mu said again and looked at Miao Xiaobai.

Miao Xiaobai frowned and said, "Brother, I think we should try another method. After all, we jumped down from the ground when we came here. It's not scientific to go back and jump down from here again. According to the law of conservation of energy..."

Before Miao Xiaobai could finish his words, Li Mu jumped down. Miao Xiaobai opened his mouth slightly, sighed helplessly, and then jumped down with Li Mu. Jiang Yun watched Li Mu and Miao Xiaobai fall into the abyss with a look of horror on her face. Watching the world return to peace again, and thinking about having to endure such lonely days in the future, Jiang Yun gritted his teeth, closed his eyes and jumped down.

Feeling the whistling sound of the wind in her ears, Jiang Yun was extremely frightened and closed her eyes tighter. Although she was already a super-powered level 11 warrior, she had been living alone here since she acquired this powerful ability, and her character had not been tempered, and she was not much different from an ordinary little girl.

An unknown amount of time had passed before the whistling wind in her ears gradually stopped and she felt her body falling slower. Jiang Yun then dared to carefully open her eyes. Although it was still pitch black all around her, Jiang Yun was not an ordinary person and could still see the surrounding cave walls with her ability.

She found that her descent speed had indeed slowed down. Strictly speaking, she actually felt a downward gravity pulling her down. The reason why she was still moving forward was just due to her previous inertia.

"Stupid woman, why are you still in a daze? Hurry up and grab the cave wall next to you!" Meow Xiaobai shouted.

Jiang Yun looked carefully and saw that not far ahead, Li Mu and Miao Xiaobai were "standing upside down" on a protruding stone surface on the cave wall, looking at her.

While Jiang Yun was hesitating, she felt that she had completely lost her "falling" speed, and her body quickly fell towards the direction she came from.

"Ah~" Jiang Yun, who hadn't figured out the current situation yet, couldn't help but scream.

At this moment, a rope suddenly appeared in front of her. Without any hesitation, she reached out and grabbed it firmly.

"You're too dull, and your reactions are too slow." Miao Xiaobai's words were full of ridicule.

Jiang Yun didn't pay any attention to Miao Xiaobai's ridicule. He glanced at the other end of the passage he came from with lingering fear. Then he raised his head and looked at the other end of the passage, his mind full of confusion.

"Let's go, the exit should not be far away." Li Mu said lightly.

After hearing what Li Mu said, Jiang Yun came back to her senses and thanked Li Mu. If Li Mu hadn't thrown her a rope just now, she wouldn't know where she would be now.

Then the two men and the tiger used all four limbs to move quickly along the wall of the cave. They were not ordinary people, and it seemed as if they were walking on flat ground in this cave. About half an hour later, a ray of light appeared above.

The few of them sped up, and soon they came out of the underground passage and appeared on Mount Everest again.

Looking at the boundless blue sky and the endless snow, Jiang Yun was dumbfounded and murmured, "Here... is this the center of the earth?"

"Little girl, I'm not looking down on you, but is it possible that the world where your ancestors lived is the center of the earth, and this place is the big world outside?" Meow Xiaobai said slowly.

"This... this..." Jiang Yun was powerless to refute. In fact, she had the answer in her heart the moment she saw the world in front of her. However, the inner world was where she had lived since she was a child. She still couldn't accept that the world was a small world in the center of the earth. This completely collapsed her worldview.

While Jiang Yun was still immersed in shock, Li Mu had already taken out the flying car.

"Get in the car. Do you want to fly by yourself?" Jiang Yun came back to her senses at Miao Xiaobai's urging.

"Oh, okay." Jiang Yun responded quickly and got into the car. She was already exhausted after coming from the center of the earth, so she had no intention of flying now.

Sitting in the car, Jiang Yun looked left and right. Until now, she didn't know what the small box in front of her was used for, but from what Miao Xiaobai said, this thing could be used to travel, like a luxury version of a chariot. But what she didn't understand was that this thing didn't have an animal to pull it, so what would be the power?

Li Mu looked at Miao Xiaobai lying leisurely in the back seat and said unhappily, "You go drive."

"Ah? Boss, I'm so tired. Now I just want to have a good sleep." Miao Xiaobai looked bitter.

"So you want me to drive? Do you think this is appropriate?" Li Mu said.

Miao Xiaobai became deflated upon hearing this and looked at Jiang Yun again.

Jiang Yun didn't know what he was thinking about. He kept shaking his head and pretended to be determined to die rather than surrender.

Miao Xiaobai sighed and had to walk towards the front driver's seat obediently.

"Little Tiger, you've gone to the wrong place. You should get off the car and stand in front of the sedan chair." Jiang Yun reminded.

"Don't call me little tiger! Also, why should I stand in front of the car?" Miao Xiaobai asked unhappily.

"You...you are not standing in front of the car...how can you tow the car? If you sit on the car, you cannot provide power for the car. This is illogical." Jiang Yun said seriously.

Seeing that Miao Xiaobai was about to continue the argument, Li Mu said calmly, "If you don't leave, you will still be my mount."

Miao Xiaobai's momentum lost most of its momentum when he heard that. He snorted coldly, started the flying car and flew away.

The moment the car took off, Jiang Yun opened her mouth wide. She couldn't understand how this iron box could move without the traction of an animal like a horse, and even flew directly into the sky.

However, what made her even more confused after the iron box went up to the sky was why this world was so big, and this world was very strange. Unlike the inner world where she had lived since she was a child, where she could see the ground whenever she looked up or down, in this world, except for the land under her feet, there was nothing above her head and all around her.

The car was completely silent. Finally, Miao Xiaobai couldn't help but say, "Brother, there is one thing I can't figure out. Why can we jump directly from both ends of the tunnel to reach the center of the earth and the surface of the earth respectively? This is really unscientific!"

"There are too many things in this world that cannot be explained by science, such as a cat driving a car. Is this scientific?" Li Mu said lightly.

"Brother, I am a tiger!" Meow Xiaobai protested.
