Along the way, birds are very scarce and there is a great silence beneath the dense green jungle. This scene of sparse animals is not very comfortable to watch.

Lu Yiming just licked his dry lips, paying attention to the heat of the ceramic fragments on his chest at any time.

There is no fever.

The helicopter flew up the river for about 80 kilometers, then found a fairly flat clearing, and after a successful landing, all the expedition members stepped off the helicopter.

"Report, this is the second team, and we arrived at our destination safely."

The voice in the headset said: "The first team has also reported that everything is safe." ”

Lu Yiming carefully stepped on the ground full of fallen leaves under his feet. The leaves made a "creaking" sound, and as the rate of decay could not keep up with the speed of falling leaves, a large layer was piled up.

Some small centipede-like bugs crawled out of the fallen leaves in a panic. Each of them wears protective clothing, which is a little hotter but can effectively avoid insect attacks.

He breathed a sigh of relief, and then took out the drone in his backpack, and his mind was attached to it, the drone started, flew to an altitude of more than 30 meters, and carefully scouted around.

"For the time being...... No problem. Lu Yiming made a gesture to his teammates.

"Everyone should bring their own protective masks...... Don't let up! Shi Dayong screamed softly in the headphones, and waved his hand again: "Let's go!" ”

The whole procession dispersed in the shape of a swallow, and soon arrived at the site of the wisdom civilization, where people found all kinds of cars parked on the side of the road, piled with leaves, as well as rusty steel bars, billboards, and so on.

The remnants of this intelligent civilization are too big!

It's the size of a big city!

A team of 25 people can only explore a small corner in a day, and even three or five months may not be able to explore it all.

Their priority targets were naturally those large buildings that were relatively well preserved.

"How do I feel here, this flat square is a former pier? You look at these boxes, it's kind of like a shipping container...... These are supposed to be ...... Cranes? Only the dock needs so many cranes. And this, probably...... No, the structure of these mechanical creations is a little different from ours. ”

"These machines ...... Is it a truck? It looks a bit like that. ”

The machines of the parallel world are a little different from the ones of the Earth civilization, for example, the steering wheel of some cars is on the right. It's just a pity that due to the passage of too much time, coupled with the wind and rain, these rusty machinery have long been unable to start.

The concrete pavement of the square cracked completely, and some of the hardy plants emerged from the cracks and grew wildly into the sun, some of which were at least fifty years old, judging by the thickness of the trunks.

Buildings are collapsing everywhere, and this scene of ruins is reminiscent of the apocalyptic catastrophe that once occurred.

"Fifty years, maybe seventy or eighty years."

A geography professor seemed to have stepped on something, and he shoveled it out with a few strokes of his shovel and patted the dust on it. He seemed to think of something: "Look, this is the robotic arm of the crane...... I see, this was originally a coastal city! ”

"Due to the large amount of water resources in the ocean entering the Yang River, over time, the amount of sea water on the planet has decreased, and the coastline has increased by more than 80 kilometers."

"After the sea water decreased, and the original coastal cities became inland cities, the geography of the planet has changed because of the appearance of the Yang River."

In the next 100 years without human beings, will abandoned cities become like this?

Lu Yiming sighed in his heart, perhaps, the disappearance of human beings is a good thing for other species...... At least all the plants are free to grow as they please.

After walking for about half an hour, the expedition team finally found a building that looked fairly intact. A glass door in the middle is hidden, and there are several large cracks in the middle, and the whole glass seems to shatter directly when touched.

Lu Yiming made a gesture to signal everyone to remain vigilant, and then he took a deep breath and gently pushed the glass door open.

"Squeak" a soft sound!

Dust was falling from the door.

Dozens of guns were aimed at the gate, ready to fire at any time.

After waiting for a while, the dust fell back to the ground, and nothing came out of it.

After making a few gestures, Lu Yiming controlled a small drone and flew into the glass door.

Lu Yiming said softly: "This may be a former office building, we have a front desk on the left, and there are some scattered documents on the cabinet. On the right-hand side of the direction were a few coffee tables and chairs, but they were all rotten and useless. ”

Intelligent life in parallel worlds is most likely homologous to humans, and has a lot in common with earthlings from a cultural level.

For example, sofas, beds, dining tables, chairs, etc., except for the differences in details, the general structure of these furniture is basically the same.

This is called cultural commonality.

Under the control of Lu Yiming, the small drone carefully reconnoitred in this building, and there was no big problem on the first floor, and then flew to the second and third floors, and reconnoitred the rooms with open doors one by one.

Just as he was heading to the fourth floor, Lu Yiming suddenly heard a strange sound of "plopping", and his brows immediately furrowed.

Naturally, the configuration of this small drone is quite high, there are as many as six cameras alone, and it is equipped with a high-end sound wave receiving device, which can hear sounds that cannot be heard by the human ear.

The voice...... How is it a bit like ...... The sound of a heartbeat? ”

As the drone explored, getting closer and closer to the sound source, Lu Yiming's face turned pale, and he felt his heart beat with this sound.

It's uncomfortable, as if the heart is merely held by an invisible hand!

Lu Yiming controlled the drone and stopped in place, not daring to move forward rashly.

"There's something here! Do you feel the same way? ”

Teammates gathered in front of the operation screen can also see the information feedback of the drone.

Zhong Peng nodded, his face was not very good-looking, and he took the lead in saying: "I heard that voice, my heart is not very comfortable, it seems to be beating with it...... It's bearable, though. ”

“…… There may be something in the house. ”
