This quick passage to and from the underground world is really shocking!

He originally thought that they just wanted to find a way to get back above the ground, but now it seems...

seem……

Are you going to open a two-way channel?!

this……

Xu Xin's expression became slightly serious.

This means that after opening this channel, this channel will always exist, and they can travel to and from the underground world through this channel.

But this involves a problem.

Are they the only survivors who can travel to and from the underground world through this passage?

Or could it be that creatures from the underground world...are also possible?

Is this an open channel, or is it a channel controlled by them?

If it was an open passage, I'm afraid they would be in big trouble even if they went out.

but……

A trace of helplessness flashed in Xu Xin's eyes.

This is also something that can't be helped.

Even if it's an open passage, they have to open it.

Otherwise, the activity cannot be completed, and the six of them will... "leave this beautiful world forever."

Let's save our lives first.

"So, how is it, what did you see?" Wen Gui was pleased to see Xu Xin's expression was very interesting, and immediately asked curiously.

"...this key..."

Xu Xin told them the information he saw.

"Branches of vine bundles?" Several people around them immediately thought of the six vine bundles that brought them to this underground world.

"What I'm talking about are the vine bundles outside. There are a total of six keys and six branch prisons. The number is exactly right." Wen Guixin immediately said.

"That should be right." Xu Xin nodded, "It must be those vine bundle branches."

"Hey wait," Zhao Xiaochuan looked at the key in Xu Xin's hand and was a little confused: "What do you mean, vine bundle branch prison? The location cannot be..."

"That's where the six vine bundle branches connect to the ground!" Lou Fei'er reacted and exclaimed, then her face turned bitter, "No!

Then should I go back..."

Thinking of what she had experienced when she arrived, she felt bad all over.

"If there are six keys in total, are the other five also in this warehouse?" Wang Lei looked around.

"Let's find all the six keys first. By the way, you must have discovered a lot of good things, right?" Wen Guixin tossed an ore in her hand and said with a smile, "Xu Xin, this one in my hand is also

Gold level?"

The piece of metal ore in her hand was indeed emitting golden light.

"Yes, it is indeed gold level." Xu Xin nodded, not only looked at the two of them more, but then suppressed curiosity and said, "Okay, let's just put all the other things into the backpack and find the other five first.

Let's talk about the key, it's not safe here, it's better to find what we really need as soon as possible."

Especially for those stone statues, no one knows whether they will suddenly move or not. It is best to find the keys they need as soon as possible.

"good."

"Split up!"

Everyone now found their way and immediately spread out, looking for keys that might be on the shelves.

"Hey!"

Before Xu Xin started looking, Coco suddenly emerged from the group of stone statues and grabbed Xu Xin's leg.

Then he turned around, ran for two steps, looked back at Xu Xin and said, "Hey!"

Are you asking yourself to follow?

Could it be that Coco also found something?

He immediately followed Coco and came to a shelf.

"Hey!" Coco climbed to the top of the shelf twice, and then with a flick of her paw, a key fell down.

Xu Xin immediately reached out and took over.

Sure enough, this is the second [Vine Bundle Key]!

"Good job Coco!" Xu Xin immediately rubbed the little head of Coco who jumped off the shelf.

"Hey!" Coco raised her head and continued to lead the way.

This little guy has been missing for so long. Did he find all the keys?

He immediately continued to follow Coco, and soon came to a corner of the warehouse.

There are no shelves in this corner, but the floor is covered with large sacks one after another, bulging inside, and I don’t know what they contain.

The sacks themselves were very ordinary green-grade sacks, but from the untied mouths of some sacks and the damaged gaps in some sacks, purple light was revealed.

"Hey!" Coco climbed into the pile of sacks and pushed a large bag among them.

Xu Xin immediately stepped in and picked up the large sack pointed by Ke Ke.

Oops, quite heavy!

[Growth feed (purple): Feed that can make juvenile organisms quickly grow into adults, but the relative life span will also be shortened. Use with caution for non-mutated organisms.]

Good guy!

This is……

Feed that can accelerate the growth of mutated organisms!

Everything in this warehouse seems to be related to cultivating mutant creatures!

This thing is a good thing, put it all away!

"Hey!" Coco got directly into the gap exposed after picking up the sack, and poked out his little head two seconds later.

At this time, in its mouth, it was biting a large key that exuded golden light.

Good guy, it found him again!

Xu Xin immediately put the keys away and asked, "Keke, have you found any other keys?"

"Hey!" Coco nodded her little head, then jumped out from the pile of sacks, wanting to take Xu Xin with her to find it.

"Wait." Xu Xin stopped Coco.

"Huh?" Coco turned around and tilted her little head.

Xu Xin turned the bracelet and released the Mimic.

Since there is a Mimic, there is no need for him to go to great lengths to collect these things.

"You swallow all these things and keep them, be careful."

The Mimic's lid clicked twice, then opened its bloody mouth, and countless vines sprang out.

Xu Xin followed Coco and continued walking, while shouting to others: "Coco can find the key. We have found the third one. Leave the key to us. Please try your best to collect the things on the shelves!"

"Ah, that couldn't be better!"

"Holy shit, is that Brother Xin's Mimic Monster? It looks so interesting!"

"Hurry up and collect your things. Who knows if these stone statues will suddenly wake up!"

Others were not too surprised about this magical red panda raised by Xu Xin.

Soon, Coco led Xu Xin through the group of stone statues, arriving at one location after another, and pulled out a golden key from various corners.

I have to say that these locations are really hard to find. Basically, you can’t find them unless you collect all the resources and things.

The Mimic is also very efficient. After quickly eating the pile of feed and keeping it, it follows Xu Xin. Basically, the resources that exist wherever he goes are sucked into the Mimic's belly.

Along the way, he also saw a lot of resources.

In addition to the mutated biological agents, growth feed, and metal bombs he had seen before, he also saw a kind of metal ore.

These metal ores come in blue grade, purple grade, and gold grade.

Is this the ore that Wen Guixin just threw in his hand?

He picked up a piece of gold-grade ore.

[Meteorite ore (gold): A kind of extraterrestrial meteorite that came to this world with dozens of meteorites fifty years ago. It is extremely difficult to smelt. 】

There was not much introduction, but Xu Xin was slightly surprised.
