Before, it was going up the mountain, and the speed of the journey was not much faster. After turning around and heading south, the long slope made everyone move much faster.

At first, Li You was going to ask where the location of this place was the original earth, but he swallowed back when the words came to his mouth, after all, this world may not be the same as his.

Descending down the mountain, a rushing river with a splash of water appeared before their eyes. Above the river, there is a bridge made of giant trees and grass, and the skin is carbonized, and the black paint is very conspicuous.

"You guys go over, and my team and I will stay here." After Sister Hua finished speaking, she began to assign the route of the team's patrol.

Peng Lao walked towards the bridge without looking back, and said to Li You after crossing the bridge: "Don't talk too much for a while, these old guys have a very strange temper." ”

Li You nodded, and said in his heart that you are not much better.

As the old and young walked along the wide avenue, Li You noticed, and none of the buildings were covered in moss, probably because of the sunshine.

On both sides of the road, all of them are one-piece buildings made of concrete, which were frozen apart due to the ice age, and only a few buildings still retain their intact structure, but there is no sign of human life.

When I walked inside, the surroundings became more spacious. Li You first noticed two rows of huge radars not far from the left, as well as a cylindrical object tens of meters long in front of him, and was immediately amazed.

"How's that, spectacular! This is now the only well-preserved astronomical telescope on Earth. Peng Lao walked forward excitedly, and Li You hurriedly followed him.

Walking up to what seemed to be a circular square, Peng Lao opened his mouth again and said, "What we are stepping on now is the launch pad that launched the spacecraft back then. Be careful, don't go in the middle, this port isn't so sturdy. ”

After hearing this, Li You hurriedly flashed to the side, and asked curiously, "How deep is this?" ”

"You'll find out in a moment."

After crossing the square, I saw two strong men walking out of a white laughing house, and after seeing Peng Lao, he nodded respectfully, then looked at Li You, and asked, "Peng Lao, who is this?" ”

"Traveler of time."

"Time and space...... The traveler? ”

Peng Lao said impatiently: "You can't understand it, is Lao Yuan down there?" ”

"Yes, I'll open the door for you."

As they spoke, Li You heard a strange voice coming from the left, and when he turned his head, it turned out that the two rows of radars were spinning, as if they were adjusting their positions.

"Peng Lao, are there still artificial satellites around the earth now?"

Peng Lao said while waiting to open the door: "Yes, but now the earth's atmosphere has been reset, and the signal is relatively weak. The current earth should be in the late stage of the ice age, and I am afraid that I will not live to the day when the earth is completely reborn. ”

"It's still in the Ice Age, so it's no wonder that I don't feel warm when I stand under the sun." Li You looked at the sun hiding from the cat, and fastened the top button of the collar.

When Peng Lao saw the door open, he said to Li You with a smile: "It is also a rare experience to be able to feel the cold on the equator. ”

Equator? Li You was speechless in surprise, feeling that he was now closest to the sun, if this was somewhere else, I am afraid it would still be covered with ice and snow.

The two took the coat and hat and other warm clothes handed over by the guard, and after putting them on, under the leadership of Peng Lao, the two walked quickly inside.

Seeing the bottomless staircase, Li You finally understood what Elder Peng meant just now. Sighing helplessly, Bai Huahua's sigh told him that he was being given a warning about how low the temperature was in it.

When Li You's legs began to tremble, he finally saw the ground covered with frost, and hurriedly walked two steps to stand on it. After the two of them were let into the house by the guards, the sharp rise in temperature made Li You's ears itch a little.

"Eh, Lao Peng, I've finally looked forward to you."

Li You was still taking off his coat and hat, he heard an unfamiliar voice in his ears, and when he looked up, an old man who was also wearing a white coat was greeting Peng Lao warmly.

According to Li You's analysis, this person should be European, blonde and blue-eyed; His face was full of wrinkles, but he could tell that he must have been handsome when he was young. I just don't know why, people in this world are speaking Chinese.

He approached Peng Lao and asked curiously: "Peng Lao, I wanted to ask from the beginning, why everyone is speaking Chinese." ”

"Hahaha, this young man is the 'Time Traveler' you mentioned! Young man, let me explain to you, in fact, we all speak our own mother tongue, but after the formation of the coalition government, a translation chip was installed in the language center of everyone's brain, and this bad habit has been passed down to this day. ”

"Bad habits?"

Peng Lao took off his clothes, straightened his waist and said: "Hey, Lao Yuan has always opposed this kind of behavior that restricts imagination and changes the structure of the human body without authorization, so all human modification experiments are called rough habits. ”

"I'm right, people are what they should be, how can they change without permission?"

Peng Lao shook his head with a smile and said, "Forget it, I can't compete with you." To introduce, this young man is what I call a traveler who has traveled through time and space. Young man, this is the Yuan Lao and Yuan Aida who I mentioned to you, who is proficient in quantum physics. ”

"Hello, I'm glad to see you!"

A European, with a Chinese surname, made Li You awkward for a long time, but he still shook hands politely.

"What a mastery, it's fur. To be honest, I still often have the feeling of being in a primitive society, a lot of questions that I can't figure out, and I don't know how to figure it out. ”

As they spoke, the three of them walked to a gate in front of them, and Yuan Aida pressed the button next to the door, and the airtight door opened.

"Old Yuan, we've been in for a long time, why haven't you seen anyone else?" After entering the airtight door, Peng Lao hurriedly asked.

Yuan Aida took out three pairs of disposable gloves and masks from the drawer, handed them to the two and said, "I heard them say that they seem to have received a signal, and they are studying whether it was sent by the group of people who left." ”

"Really?"

When Li You saw Peng Lao say this, he didn't show any joy, but that worried expression. There was a bad premonition in my heart. Logically speaking, this is definitely a good thing, the expression is flat, but it is the kind of nervousness and worry.

It's definitely not that simple. Although he suspected that there was a conspiracy here, he did not show it, put on his gloves and mask, and walked to the test bench not far away.

"Hey, it's not good to say, I said a long time ago, their methods are too cruel, in case they ......" Yuan Aida didn't finish his words before he was interrupted by Peng Lao, and the two looked at each other meaningfully and walked to Li You's side.

Yuan Aida adjusted the electron microscope and asked Peng Lao to take a look. After reading it, Peng Lao asked in surprise:

"How did this cell get encased in a fungus?"
