In the earth cabin.

"Underworld troops? Are you talking about those aliens just now?" Miao Siaojun asked doubtfully.

Chen Kai sat on a chair, crossed his legs, crossed his arms, and said in a calm tone: "That's the Lion King's army. The soldiers of the underworld are still in the fifth parallel universe, but if they want to come, they will only take a few breaths."

time."

"Then...then if they attack the earth, can our earth's army be able to withstand it? Also, what is the fifth parallel universe?" Huo Linfei looked at Chen Kai who was leisurely crossing his legs in confusion and asked.

"With the current strength of the earth, it will take about three and a half hours at most. After that, they will lose all resistance, and then ground transportation will be completely paralyzed. As for the fifth parallel universe, I can't explain this very well."

Chen Kai's tone of reply was calm and his expression was leisurely, as if none of this was his business.

When Huo Linfei and Xiaopangdun heard this, their expressions changed, and they shouted in unison: "Then it's the end of the world for our earth, ah, help!"

"Don't worry, as long as I am here, I will not let the earth be threatened by alien artillery fire." Chen Kai exuded a kind of domineering aura, a domineering aura belonging to a king. The earth has special meaning to Chen Kai, although this

It is not the Earth of the original world, but this is also what the Earth is not.

A man must not forget his roots. Chen Kai has a clear distinction between good and evil, and he is also decisive in killing. If the army of the underworld really comes to invade the earth, he will not mind letting them sleep here forever!

Tianyu looked at Huo Linfei and Xiaopangdun, covered his face helplessly, shook his head randomly, and said to Xuan Yizi: "Master, are these two guys really the people we are looking for? They are really useless, right?

."

"Baboo, baboo!" Baboo flew out, agreeing very much with Tianyu's point of view.

"Pah!" Little Fatty slapped Baboo on the body and said, "What's the fuss about? The adults should speak, and the children should not interrupt."

Xuan Yizi walked to the bookshelf, turned a desk lamp next to the bookshelf, and then the bookshelf opened to both sides, and a display screen appeared.

"Huo Linfei, have you all forgotten the parallel universe?" As Xuan Yizi finished speaking, the screen opened.

"Parallel universe? Does this have anything to do with the fifth parallel universe?" Huo Linfei asked, looking at the screen in confusion.

"I hope this is a lively physics class." The little chubby boy's tone began to fade. He was unwilling to learn boring knowledge.

"In fact, our universe is composed of several parallel sub-universes. These universes usually maintain a parallel state. There is no intersection and there is no way to travel through them. Things in parallel universes have a high degree of symmetry, or similarity. For example

It is said that in another parallel universe, there will be people who look exactly like you, Huo Linfei." Xuan Yizi explained to Huo Linfei and Miao Shoujun in a slow tone.

"ah!"

Huo Linfei felt incredible.

"Then in another parallel universe, is there Slim Jun who looks exactly like me?"

Little Fatty was also very curious and asked Xuan Yizi what he thought.

"certainly."

Xuan Yizi felt very cute about this child and answered him.

"Then if he comes here to find me, I won't be in much trouble."

Little Fatty said.

"Impossible. Because parallel universes cannot be traversed under normal circumstances."

While Xuan Yizi was answering, several flat graphics also appeared on the big screen, connected by a cylinder in the middle.

"What about the second-case scenario?"

Little Fatty asked a very funny and boring question.

"Good question."

"Every 100,000 years, the parallel universes will experience space-time distortion due to their strong gravity. As a result, the parallel universes that do not intersect will have a seven-day space-time intersection. During these seven days, if there is a strong enough force,

With different energy, you can travel between these parallel universes."

Xuan Yizi looked at the big screen and gave Xiaopangdun answers.

"And yesterday was the first day of these seven days."

Tianyu stepped forward and answered.

"Oh, I understand. Those underworld warriors must be from other parallel universes."

Huo Linfei finally had an enlightenment and expressed his inner thoughts.

"Yes, they come from the underworld. A fifth parallel universe infinitely far away from here."

"Then why does that Lion King know me? I don't seem to have met him. Also, why did he give me this? Why is this?" Huo Linfei looked at the power lock in his hand and asked.

road.

"Because, eternal reincarnation." This problem of Huo Linfei cannot be regarded as a problem at all. Everyone except Huo Linfei knows it.

"It's eternal reincarnation again. What is this eternal reincarnation?" Huo Linfei was upset and angry. He had heard about this eternal reincarnation either once or he didn't know the answer.

"Eternal reincarnation means that our universe will repeat itself every hundred thousand years. However, within this repetition, there is non-repetition, and within the non-repetition, there is constant repetition." Xuan Yizi spoke slowly.

: "And now, one hundred thousand years have passed, and the underworld wants to come back again, and the first thing they do is to get the key to unlock Hades' seal."

When Xuan Yizi said this, his eyes stayed on Chen Kai for a while.

Chen Kai was wondering why this old dirty turtle would stay on his body. Did he really do something earth-shattering a hundred thousand years ago?

"Wait a minute, isn't it possible that what Chen Kai gave to the Lion King just now is...?" Huo Linfei seemed to have remembered something and asked.

"The Key to Xuan Ming!" Tian Yu glanced at Chen Kai, his tone full of helplessness.

"Ah! It's not such a coincidence!" Huo Linfei looked like his parents were dead.

"Chen Kai, why did you give such an important thing to the Lion King yesterday? Now we are going to have a big adventure in the universe, okay!" Huo Linfei held his head in his hands and shouted at Chen as if crying for his father and mother.

Kai yelled.

Chen Kai frowned when Huo Linfei yelled, and his expression was obviously not good-looking.

At this moment, Xuan Yizi poked the ground with his spiritual snake staff, making a thumping sound, which attracted everyone's attention, and then slowly said: "Okay, okay, everything is doomed.

, even if Chen Kai doesn't give them, they will have other means to obtain the Key to the Mysterious World. There are some things in the world that we cannot change."

"Come with me." Xuan Yizi stood up and walked towards a place in the room.

Chen Kai and Tian Yu both stood up and followed. Huo Linfei and Xiao Pang Dun also looked at each other and followed.

Little Fatty even ran to Xuan Yizi and asked, "Senior, where are we going?"

Xuan Yizi looked at Slim Jun and smiled mysteriously. Finally, they stopped in front of a cabinet, and everyone stopped as well.

The spirit snake staff in Xuanyizi's hand quickly clicked on different drawers. The drawers that were clicked glowed in the order that Xuanyizi clicked. Then the cabinet opened to both sides, and a lifting platform appeared.

"Come with me." Xuan Yizi waved and walked onto the lifting platform. Then Xiaopangdun, who was closest to Xuan Yizi, walked up second. Tian Yu, Chen Kai and Huo Linfei left almost at the same time.

Go up.

The lifting platform began to move and kept moving downward. After an unknown amount of time, the lifting platform stopped and the safety door on the platform opened.

Xuan Yizi walked in front, Xiao Pangdun followed Xuan Yizi, Tian Yu, Chen Kai, and Huo Linfei followed behind.

Xiao Pangdun looked at the darkness all around and asked Xuan Yizi: "Senior, your basement is so hidden, you must have hidden a lot of secret weapons, right?"

"Haha, there is only one old spaceship." Xuan Yizi chuckled and replied.

"Oh, old spaceship, how old is it?" Huo Linfei said.

"Older than me." As he said that, Xuan Yizi walked to the operating table not far away. After a while of operation, all the lights in the basement came on.

A huge green spaceship also appeared in front of everyone.

"What a ship..." Huo Linfei looked at the huge Xuanwu in front of him, slightly surprised.

"Old spaceship!" Xiao Pang Dun answered Huo Linfei's words. He really is a good friend.

"Is this the Xuanwu? I didn't expect it to be so new in this dark basement for a hundred thousand years." Chen Kai looked at the Xuanwu, which exuded a brand-new light, and couldn't help but sigh.

The technological content of the Xuanwu is higher than that of the Iron Dragon World. If nothing else, the super artificial intelligence system Lisa is no worse than Cortana.

"Yes!" Xuan Yizi reached out and stroked the Xuanwu as he spoke, and said in a very nostalgic tone: "Old man, we have to fight side by side again this time."
