Sure enough, there was no wall behind the waterfall, so he went straight in.
Ji Chaoyang, Yin Wang and Coco had already come in when he was picking up the purple crystal.
Silver King and Coco crossed the waterfall. Coco's body was also soaked. The two beasts were shaking off the water on their bodies at the entrance, which happened to splash all over Xu Xin's face as he came up.
Xu Xin rubbed Coco's wet head and stood up from the ground.
When he stood up, he staggered and almost fell.
"……iron?"
The ground was a smooth iron surface, which became very slippery after getting wet, which caused Xu Xin, who had not been paying attention, to almost slip.
Behind him, a soft yet penetrating white light filtered through the thin curtain of water from the waterfall, illuminating the entire room clearly.
"This room..." Xu Xin's expression changed.
He originally thought that there would be a stone cave space like the Water Curtain Cave behind, but unexpectedly, it was actually an iron room!
The room is not big, only a few dozen square meters, but it is about five or six meters high, and all six sides, front, back, left, right, top and bottom, are made of pure iron.
It's an iron lump completely surrounded by iron!
He was very familiar with this structure, and it even reminded him of some not-so-nice memories.
The memory of being chased by the red fog and climbing the ladder in a panic.
After coming to this world, he had only seen an iron room once, which was at the bottom of the passage at the entrance to the underground world!
At that time, he climbed down a long rusty iron passage and finally entered such an iron room!
At that time, there was a skeleton wearing adventurer's clothes in the iron room. The skeleton was carrying things brought from the earth, and on the back of the skeleton, there was a sentence engraved, but it was in Greek, which he really couldn't understand.
"Ah!" Keke also screamed and climbed onto Xu Xin's shoulders in two moves.
It also recalled the experience at that time.
At that time, it went to the underground world with Xu Xin, and was frightened by the giant monsters in the underground world!
Xu Xin touched Coco's little head and subconsciously looked at the crack in the floor of the iron room.
Last time, it was from the cracks in the floor of this iron room that thick red mist gushed out, forcing Xu Xin to climb up desperately. Finally, at the critical moment, he escaped from the iron passage and closed the iron door.
Thinking back on it now, he still feels scared.
Thinking about the location here...
Could it be that the red fog that suddenly filled the entire salt mine cave just now came out from the cracks in the ground of this room?
Xu Xin looked at the junction of the floor and the wall of the room, and indeed, he could see a tiny black gap!
Maybe, it was really as he imagined!
Then behind one of the walls of this room should be the salt mine cave!
Xu Xin looked at the four walls.
The place where he climbed in from the lake through the waterfall was the door of this iron room. It was the same door that he had pried open with his hands, except that this time the iron door was completely open.
The four walls looked nothing special. The room was completely empty, with bare walls, and it looked like a tin prison.
In the previous room there was a skeleton sitting in the corner, but this room was empty.
But Xu Xin suddenly became alert. He remembered that he had closed this door by himself in that iron room.
Ji Chaoyang had already walked around this iron room and observed every corner.
"How is it? Is there anything special about it?" Xu Xin asked.
"No," Ji Chaoyang shook his head. "There's nothing in this room, not even a single inscription. All the walls are spotless."
After hearing this, Xu Xin came to the iron wall facing the iron gate.
Judging from the location and direction, if there is a wall here that is the wall that just cracked in the salt mine cave, it is this wall.
Combined with the situation just now, the faint white light emanating from the cracked wall just fits the environment of this room. Moreover, recalling that when he fled towards the salt mine entrance, the sound of the wind he heard behind him seemed to be the sound of mist gushing out from the cracks in the floor of this iron room!
He was now almost certain that behind the cracked wall of the salt mine was this iron room!
However, why is there such an iron room behind the waterfall in this paradise-like place?
He told Ji Chaoyang his speculation.
"You said..." Xu Xin looked at the wall, "If we break it down, can we return to our original position?"
"Maybe? There is no exit nearby, so we should give it a try. However, no matter whether it is possible or not, let's go outside first and collect those resources." Ji Chaoyang said, looking at the waterfall.
"Yeah, that's true. However, this iron room is basically the same as last time," Xu Xin pointed to the door at the waterfall. "Even the style of the door is exactly the same."
"Yeah." Ji Chaoyang looked up at the top, "There's no escape route for us this time. If the door is closed and the fog is released again, it will be difficult to deal with."
Ji Chaoyang had the same experience as Xu Xin. In the end, the door was closed and red fog was released, and they climbed up in a panic as if they were escaping.
So both of them had some concerns about the combination of the foul-smelling thick red fog and the closed room.
However, Xu Xin had a guess.
If they close the door and let the mist in...will the wall crack? Will they be able to enter the salt mine?
Well, the entrance to the salt mine will also be closed as the wall cracks, so this probably isn't a good idea...
After taking another look at the smooth iron wall without any marks, Xu Xin turned around and said, "I feel that we shouldn't stay here for long. Otherwise, we will be locked up again like we have been through. We should hurry out and get the resources outside first."
