Liu Xuan and the others got on the spaceship and followed the Black Armor Lady to the depths of the forest.

"Where are we going?" Liu Xuan asked, and the old man said;

"To Blackwater." The old man said;

"Blackwater? Is it a city built in black water? Liu Xuan felt that this name was too strange.

"Yes, a city built in black water." The old man said;

"This... Liu Xuan suddenly had nothing to say.

The spaceship passed through the forest and came to a lake, and when you looked down from the sky, there was a large black lake in the middle of the forest.

Suddenly the lake was churning, and a big platform came up in the middle of the lake, and the old man asked Dr. Qiu to park the spaceship on it, and the flying dragon Xiaohua saw that the spaceship had landed, so he also landed next to it, and suddenly an elevator lowered the spaceship and Xiaohua, and went down to the lake, and after a while, the platform also sank to the bottom of the lake, and after a while, the lake surface returned to calm, and the forest also returned to calm.

Liu Xuan was surprised to see that a city had been built under the lake.

Liu Xuan and the others sat on the elevator all the way down, and it took a long time.

As soon as you get out of the cabin, you will see a huge underground world, with many high-rise buildings below. When Liu Xuan saw this scene, he couldn't help but think of the dungeon in Neon Genesis Evangelion, but the scale here was far greater.

"Tsk, it's hard to see this Blackwater City." Dr. Qiu was the first to sigh;

"Wow, it's huge, this underground city is really big." Feng Yu couldn't help but sigh.

"Wow..." The fat man's mouth grew in surprise, and saliva flowed down his mouth.

Even the dragon flower looked around and felt a magical underground world.

"You are really a group of people who have never seen the world, what is this big, it is less than one percent of Xuancheng" Wenwen saw a group of people making a fuss and couldn't help but complain.

"Come with me, all of you." I don't know when, the Black Armor Lady has already come to everyone.

Liu Xuan followed the black armor lady to a huge hall, there were two rows of red armor guards standing at the entrance of the hall, the hall was very large, dozens of meters high, the wall was metallic, there were eight metal chairs in the center of the hall, forming a circle, and there was a table in the center of the circle. In each chair sat an old man who looked older, all of them looking weak, and even older than the old man.

As soon as the old man came in, he and the black armor lady saluted the eight old elders, while Liu Xuan and the others were all standing at the door.

"Hehe, the little sand is back." One of the elders said;

"Little fool? It turned out that the grandfather was called the little fool. Liu Xuan heard the muttering;

"You're a little fool, you're sand." Wenwen glanced at Liu Xuan and said;

"Fools?" Liu Xuan asked;

"Sand, the sand of the desert." Wen Wen glared at Liu Xuan fiercely and said;

"Oh, it's called Grandpa Sha." Liu Xuan said;

"Little Sand, did you bring these people?" Another elder asked;

"Time Particles." Grandpa Sha said.

"What? Are there really time particles? When the elders heard the particle of time, they were shocked and began to talk.

"Do the people of Xuancheng know about this?" Another elder said;

"I don't know, it's said that the person who discovered the particle of time was a scientist from Xuancheng, but he was killed, but I brought the scientist's assistant." After the old man finished speaking, he immediately called Dr. Qiu over.

Dr. Qiu told the elders everything he knew, and then called Liu Xuan in.

After Liu Xuan came in, he found that the people in the chair were all holographic projections, and they looked so real.

The elders could only sit in their chairs and look at Liu Xuan, but they didn't see anything special about Liu Xuan.

"Time particles are on this young man right now?" One elder asked;

"Yes, according to Pablo's theory, it should be in Liu Xuan's sea of memory." Dr. Khoo explained;

What the hell is the Bablo theory, Liu Xuan doesn't understand it at all, and he doesn't know what the Sea of Memory is. Dr. Qiu and the elders discussed for a long time, but Liu Xuan didn't understand the whole process at all, and his knowledge was too profound.

"Okay, you go back and rest first, let's discuss the countermeasures with a few old men, and then I will notify you to come over." The elders all disappeared from their chairs as soon as they finished speaking.

Liu Xuan and the others came to a rest place, and each went back to the room to rest, on the way Feng Yu told Liu Xuan what they were talking about, Liu Xuan said with a blank face that he didn't know, and in exchange for Feng Yu's contempt.

What Liu Xuan has always wanted to understand is what is the relationship between this Xuancheng and this Blackwater City, and why Grandpa Sha refused to stay in Feilong Village when he heard about Xuancheng and fled to this Blackwater City.

And this time particle, how can it make time restart, I don't understand, it's mysterious.

Early the next morning, Dr. Qiu hurriedly ran to find Liu Xuan to go to the Hall of Elders, and he was in a hurry, and he didn't call the fat man and Feng Yu, nor did he explain what was going on, Liu Xuan followed Dr. Qiu to the Hall of Elders with a confused face.

Of course, the eight old guys were all sitting on the chairs, as well as Grandpa Sha and Lady Heijia.

An elder called Liu Xuan to the side, Liu Xuan walked to a chair, and sighed, this holographic projection technology is also too good, seeing that these old people are the same as real people, Liu Xuan touched the face of the old man next to him, so real. If this technology is used on some adult dolls, it will definitely sell well when it is brought back to Earth.

"You kid, what are you touching my face, we're all real now, not holographic projections." As a result, the old man who was touched by Liu Xuan next to him spoke.

The atmosphere became awkward for a while.

"Hello grandfathers, my name is Liu Xuan." Liu Xuan said in order to ease the atmosphere;

"I called everyone to come over for an emergency gathering today, to announce one thing, with the intelligence of the inside line, Xuancheng has already begun to investigate the matter of time particles, and has also found a trace of Liu Xuan, and may soon find us here in Blackwater City, when the time comes, I am afraid that there will be a huge disaster in Blackwater City." An elder opposite Liu Xuan said a little anxiously;

"It's not just Blackwater City, it's probably our entire tribal race that will perish." Another elder also said worriedly;

"It's so serious, what should I do?" Grandpa Sha couldn't help but say;

"Make the particles of time disappear." One of the elders looked at Liu Xuan with strange eyes and said;

"You can't kill me, do you?" Liu Xuan said a little worriedly;

"That's not true, according to Pablo's theory, because the time particles are scattered in your memory, you need to go back to your memory and collect the time particles, theoretically the time particles will be reactivated, time will be restarted, and then you will go back to the earth 100 years ago, and the time particles will disappear completely." Dr. Khoo explained;

"How can you go back to memory? How do you collect it? Liu Xuan still didn't understand, this logic can't be explained.

"It's to put you back in the peace elite." Dr. Khoo said;

"Back to the Peace Elite?"
