What is down here, they have wanted to know for a long time.

Only by truly solving the underground problem can their teleportation array truly be considered a safe facility.

Otherwise, you will be on tenterhooks every time you use it, which is really uncomfortable.

Several people came to the iron gate.

Coco had already run up to the iron door and tugged on the iron door a few times with her little paws.

"I'll drive it."

Xu Xin lifted Coco onto his shoulders, then squatted down and tentatively held the handle of the iron door with his hand.

The handle is still very cold, but it's much better than before.

He pulled the handle upward hard.

As a result, there was no pull.

"Huh?" He frowned and increased his strength.

The cold iron door only shook slightly, but it still could not be pulled up.

Can't pull it up?

wrong.

This iron gate should have been opened.

Because this time, unlike last time, there was a beep to indicate that the iron gate was blocked, and there was no bone-chilling chill that would directly freeze the palms of the hands.

Last time, the prompt also said that the iron gate would open after the formation is unlocked.

"Can't open it?" Wen Guixin was a little confused, "Is this door locked?"

"You can't open it either?" Ji Chaoyang frowned slightly, "I tried it once before and couldn't pull it open."

"It's probably not blocked." Xu Xin stood up and looked at the red mark on his palm caused by excessive force. "Maybe it's because it's too heavy and I can't pull it open with my strength."

"Too heavy? Let me give it a try!" Wang Lei immediately stepped forward, gearing up.

Xu Xin nodded and made room for him.

Wang Lei immediately squatted down, held the handle of the iron door with both hands, took a deep breath, and then pulled it upward!

Then, under the surprised gazes of everyone, the seemingly heavy iron door seemed to have no weight in his hands. He was directly pulled up, opened, and flipped to one side.

"Oh!" Wang Lei used too much force and fell to the ground without being able to stand firmly.

"boom!"

The iron door hit the ground heavily on the other side, raising a cloud of dust!

"Hey!" Coco immediately jumped off Xu Xin's shoulders, jumped in front of the opened iron door, and looked down.

"It's not very heavy." Wang Lei stood up from the ground and patted the dust on his butt.

Isn't it? In his hand, the iron door looks like a plastic door.

That's right, he is a strong man who can lift five hundred times his own weight.

Perhaps the iron gate is already hundreds of times heavier, and is completely unable to be pulled by Xu Xin and Ji Chaoyang.

But for Wang Lei, this weight is very easy.

"Oh! You are still strong!" Wen Guixin stood behind a few people and clapped her hands.

All five people gathered at the underground entrance. She didn't dare to get close, so she could only stand behind a few of them.

Xu Xin and Ji Chaoyang had already started standing by the opening of the opened iron door, looking inside.

In fact, the two of them were initially aware that blood-red mist might emerge from it.

After all, this entrance is very similar to the entrance to the underground world.

The same iron door, the same rust, the same door handle.

However, after opening it, there was no red mist, which made both of them breathe a sigh of relief.

But after the two of them took a look inside, their hearts began to lift again.

Inside the iron gate is a square iron passage that can only be accessed by one person.

An iron ladder is fixed on the wall on one side of the passage.

Whether it is an iron wall or an iron ladder, they are all covered with dark red rust and exude a fishy rust smell.

When you look down, you can't see the end at all.

It was pitch black.

Xu Xin was very familiar with this kind of passage.

Isn't this the same passage as the entrance to the underground world and the place where the golden treasure chest was found?!

this……

"Huh...? Huh!" Keke, who was standing by the passage with her little head tilted, thought of something and screamed, immediately crawling along Xu Xin's body and onto his shoulders.

It also followed Xu Xin through this passage, so it naturally recognized it.

At that time, Coco was very afraid of the super-large underground monsters when he was underground. Now that he thinks about the scene at that time, he is naturally a little scared.

Xu Xin touched its little head and comforted it, then turned to look at Ji Chaoyang: "In your prediction, it was going down the stairs, right?"

Influenced by Ji Chaoyang, he subconsciously believed that there would be stairs under the iron door.

Ji Chaoyang also looked solemn: "In my prophecy, I was indeed going down the stairs, and it was a spiral staircase, but... I was already on that spiral staircase at the beginning of the prophecy. As for how I got to that spiral staircase

I don’t know about the style.”

Unexpectedly, there is actually such a passage under the iron gate.

Xu Xin looked down with some solemnity.

"What's wrong?" Several other people also came over and looked inside.

"Isn't it just a passage that needs to be climbed? Is there any need to be so nervous?" Wen Guixin looked indifferent.

"You can't say that," Zhao Xiaochuan said, "If you climb on this kind of passage, if there are any traps, there is basically no way to dodge."

Xu Xin and Ji Chaoyang looked at each other and wanted to say something, but they hesitated.

Can you tell them about this?

"I have seen this passage before." Xu Xin still spoke.

"Have you seen it?" Several other people were surprised.

"It was through this passage that I found the golden treasure chest," Xu Xin said. He did not mention the underground world.

"Ah!" Wen Guixin opened her eyes, "You mean, there is a treasure down here?"

"It can't be that simple." Ji Chaoyang shook his head, "I don't know if the scene in the passage this time is the same as last time, but..."

If it really leads to the underground world, then after these people go down, it is equivalent to knowing the secret of this world?

If that was the case, he wanted to bring Li Wenxi and a few others over.

Lou Fei'er had been staring at the entrance of the cave for a long time. After being silent for a while, she walked to Xu Xin and whispered to him: "There should be that kind of red mist in this passage."

oh?

Is there also red mist?

"How did you know?" Xu Xin asked.

"Although the smell is very bland,... for me, no matter how bland it is, I can smell this smell." Lou Feier pointed to her nose.

Her words were heard by several people around her.

Others were a little confused, but Ji Chaoyang understood what it meant.

Now, the two of them are basically certain.

There is a high possibility that this passage is really connected to the underground world!

The two people who were still determined to go down were a little hesitant.

Do you want to go down and take a look?

If it's really an underground world, wouldn't it take a long time to climb down?

"Do you have a new combat force over there?" Ji Chaoyang suddenly turned to look at Xu Xin, "It's Zeng Tao, do you want to ask her to come with you? Since I have signed a contract with you, I should be able to trust you.

Bar?"

If you really want to enter the underground world, you should naturally bring all your strong combat capabilities with you.

"No." Xu Xin shook her head, "She is still in a weak stage, and..."

She cannot be involved in this matter for the time being.

She has just mutated. Although she is very strong, her mutation level is low.
