This express passage to and from the underground world is truly shocking!

He had thought they were just going to find a way to get back above ground, but now it seemed...

seem……

Is it to open a two-way channel? !

this……

Xu Xin's expression became slightly serious.

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

But this brings up a problem.

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

Or, creatures from the underground world... are also acceptable?

Is this an open channel or a channel controlled by them?

If it was an open passage, they would probably be in big trouble even if they got out.

but……

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

There is nothing we can do about this.

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, what did you see?" Wen Guixin asked curiously when she saw Xu Xin's interesting expression.

“…This key…”

Xu Xin told them what he had seen.

"Branches of vines?" The people around immediately thought of the six vines that brought them to this underground world.

"I'm talking about those bundles of vines outside. There are six keys in total, and there are also six branch prisons. The number matches exactly." Wen Guixin said immediately.

"That should be it." Xu Xin nodded. "The vines are branching out, so they must be those ones."

"Wait a minute," Zhao Xiaochuan looked at the key in Xu Xin's hand, a little confused: "What do you mean, a vine-bound branch prison? It can't be located in..."

"It's where the six vine branches connect to the ground!" Lou Feier reacted and exclaimed, then her face turned bitter, "No way!

So, should I go back?"

Thinking about her experience on the way here, she felt sick.

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

"Let's find all six keys first. By the way, I'm sure you've found a lot of goodies too, right?" Wen Guixin tossed a piece of ore in her hand and said with a smile, "Xu Xin, is this one in my hand also gold-grade?"

The metal ore in her hand was indeed emitting a golden glow.

"Yes, it is indeed gold-level." Xu Xin nodded, not only looking at the two of them a little longer, but also suppressing his curiosity, "Okay, let's just put everything else into the backpack and find the other five keys first. This place is not safe, so it's better to find what we really need as soon as possible."

Especially those stone statues, no one knows whether they will suddenly move, so it is best to find the keys they need as soon as possible.

"good."

"Separate our forces!"

Everyone now had their bearings and immediately scattered, searching for possible keys on the shelves.

“Bing!”

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

Then he turned around and ran two steps, looking back at Xu Xin: "Bing!"

Is this to make yourself catch up?

Could it be that Coco also found something?

He immediately followed Coco to a shelf.

"Ying!" Coco climbed to the top of the shelf in two steps, then with a push of her little paw, a key fell down.

Xu Xin immediately reached out to take it.

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

"Well done, Coco!" Xu Xin immediately rubbed Coco's little head as she jumped down from the shelf.

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

This little guy has been missing for so long, could he have found the keys?

He immediately continued to follow Coco and soon arrived at a corner of the warehouse.

There were no shelves in this corner, but the ground was covered with large sacks, which were bulging and no one knew what was inside.

The sacks themselves were very ordinary green-level sacks, but from the openings of some sacks that were not tied tightly, as well as from the gaps in some sacks that were damaged, purple light was revealed.

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

Xu Xin immediately stepped in and picked up the big sack that Coco pointed to.

Wow, it’s quite heavy!

[Growth Feed (Purple): This feed can rapidly grow juvenile organisms into adults, but it also shortens their lifespan. Use with caution on non-mutated organisms.]

Good job!

This is……

Feed that can accelerate the growth of mutant organisms!

Everything in this warehouse seems to be related to the cultivation and breeding of mutant creatures!

This is good stuff, let’s put it all away!

"Ying!" Coco crawled directly into the gap revealed when the sack was lifted up, and poked out her little head two seconds later.

At this moment, it was holding a large key emitting golden light in its mouth.

Wow, it found it again!

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

"Hmm!" Keke nodded her little head, then jumped out of the pile of sacks, wanting to take Xu Xin with her to look for it.
