Xu Xin walked to the iron door that looked extremely heavy.
The design of this iron door was like the door of a vault, and he was inside the door at this moment.
Xu Xin had seen how the vault door was opened in movies and games. It was done by rotating a circular disk outside the door that looked like a reverse disk. After a deflation sound, the circular door would push outward and then move horizontally to the left or right.
But he was in this room at this time, so there was no disc-like switch, so he could only try to push the door with his hands.
"Zizi-" a harsh sound of metal friction was heard, and with Xu Xin using all his strength, the door was slowly pushed open.
"There's hope!" Xu Xin was delighted when he saw the door being pushed, and continued to push hard.
"Click!" With a crisp sound, the round iron door was completely pushed out of the door frame, leaving a gap of two fingers wide between the door frame and the door.
Xu Xin did not rush to open the door, but looked outside through the gap.
He thought that there would be a modern room like a vault outside, but to his surprise, what he saw through the gap was a wall made of reddish soil, as if he had entered a cave again.
"Is there a cave outside again?" Xu Xin was a little confused.
Doesn't it mean that, buried alone underground, there is a square iron room that looks like a vault, and a European who came from their world in the 1980s died in the room
So strange.
"Keke, there is danger outside... What are you doing!?"
Xu Xin looked at Coco, who was lying on the ground and scratching the skull with her claws, and his eyes twitched.
The poor skull was rolled on the ground by Coco as if it were a ball, and slapped left and right. The scene was very weird. A cute little panda was playing with a skull.
"Hmm?" Coco looked at Xu Xin puzzledly.
That's right, Keke is a red panda, you can't expect it to be afraid of human skulls. Xu Xin shook his head helplessly: "I have to give you a good bath after we get out!"
"Bing!"
However, the little guy's fuss did help to dissipate a lot of his inexplicable fear of the skeleton.
"Coco, is there any danger outside?"
"Hmm." Coco shook his little head, indicating that he did not feel any danger.
Xu Xin took a deep breath, put his fingers into the gap, and pulled the door to one side with force.
With a sharp sound, the door was slowly opened halfway.
Xu Xin stopped, just enough for him to pass.
He walked through the door and looked outside.
Seeing everything outside the door, Xu Xin was stunned. He rubbed his eyes and looked again.
He thought it was a cave, but he was wrong, very wrong.
"Ah!" Even Coco let out a cry of surprise.
Xu Xin subconsciously took two steps forward, then suddenly stopped.
He suddenly found himself on the edge of a cliff.
That's right, on the edge of the cliff.
Small pieces of stone and soil rolled down from the edge of the cliff. Xu Xin looked down and couldn't help but clench his teeth. His facial muscles twitched and a bead of sweat slid down his forehead.
Below the cliff, at a depth of almost a thousand meters, is a huge underground world that stretches as far as the eye can see.
With the help of his night vision, he saw everything in the underground world.
"Is this... true...?" Xu Xin's lips trembled slightly as he stared blankly at everything in front of him.
He saw countless green and blood-red vines dancing wildly below.
I saw a giant carnivorous plant with its bloody mouth open, swallowing an animal that looked like a dinosaur.
I saw a huge monster covered in green seaweed, dozens of meters tall, tearing off the blood-red vines and stuffing them into its mouth.
I saw countless flying insects as big as cars with dazzling light at their tails flying around the carnivorous plant.
Demons are dancing wildly.
The scenery before him was so unreal and the amount of information was so overwhelming that he was completely stunned.
He looked around blankly again.
At this moment, he was in a cave at the top of the underground world. The top of the entire underground world was right above his head and he could touch it with his hand.
If the underground world is regarded as a huge room, then he is now a small insect in the gap between the lampshade and the ceiling, looking down at this huge room, and those monsters are the masters of the room living in this room.
The dense red dots on the map made him feel a little fear and despair.
Congratulations, you have discovered one of the hidden secrets behind this world and become the first person among this group of survivors to discover the underground world. The reward will be issued after the end of this jungle exploration activity.
Survivors please do not share the secrets of the world with people who do not know the secrets, otherwise you will be severely punished.
Don't panic. The underground world is not something the survivors can handle at this stage. How to deal with the beast riots is what the survivors need to consider now.
Survivors, please continue to work hard, strengthen yourself, and strive to live in this world.
Once again, a warm reminder: never abandon your tree house, it is your only support.
The mysterious voice sounded in his ears again, bringing him back to his senses.
Against the backdrop of these monsters, he actually felt that this mysterious voice was so familiar.
"Wait a minute! Where exactly is this place? Why is there such a large space underground and so many monsters?" Xu Xin asked the question he wanted to ask most.
The secrets of the world need to be explored by the survivors themselves
The mysterious voice only answered him with this one sentence, and no matter how he asked, it would not speak again.
At this time, Coco had already crawled into Xu Xin's arms, buried her head and shivered.
There were so many monsters below that even at a depth of a thousand meters, Xu Xin could still feel the oppression of those huge monsters, not to mention Coco.
Fortunately, the mysterious voice just said that they don’t need to deal with these huge monsters now, and they have to consider how to resolve the beast riot first. In other words, these monsters will not come out now. He just knew the content of the later version in advance.
This really made Xu Xin feel relieved.
He suddenly thought of something.
"Coco, didn't you say that the treasure chest is here? Don't tell me the treasure chest is down there, right?"
Let's find the gold treasure chest first. Xu Xin eased his current mood and rubbed the little guy's head in his arms.
"嘤!" Coco suddenly remembered this incident, jumped out of Xu Xin's arms, tugged at Xu Xin's trouser leg, and motioned Xu Xin to follow it.
Outside the huge round iron gate was not just a small hole on the cliff, there were other holes on the wall of the cave, but Xu Xin was completely shocked just now and did not notice them.
Following Coco, Xu Xin soon reached the end and saw the golden treasure chest at the end.
Even in the dark underground world, this treasure chest still emits a faint golden light, illuminating the surroundings at the end of the cave.
Xu Xin looked at the treasure chest. He first confirmed the pattern on the treasure chest. It was indeed the head of an animal, but it was different from the Qilin he had imagined. It seemed that the three treasure chests were not printed with Qilin.
Xu Xin decided to open the golden treasure chest here.
He took out the key, inserted it into the keyhole of the golden treasure chest and twisted it. A mechanical sound was heard and the treasure chest was opened.
"Ying!" Coco climbed to the edge of the golden treasure chest and looked inside.
Inside the gold treasure chest was a bottle of grey potion and a thin card.
