Chapter 301 Unknown Copy

This sound immediately made Su Yue's nerves tense.

The source of the sound pointed to the dark passage deep underground leading to an unknown destination.

Su Yue and Lu Wei followed the sound until they came to a huge reinforced concrete door.

Two months have passed since the end of the world, and the underground area behind the door is isolated from the world like an isolated island.

Su Yue had no idea what kind of alien creatures were hiding inside.

Su Yue put his hand on the door, and saw a layer of dark blue barrier rising out of thin air.

Like an invisible barrier, it blocked their way forward.

Then, a cold and mechanical system prompt sound came.

[Ding! The special copy shortcut is ahead. The system detects that you have not opened the copy yet, so you can't enter directly! ]

Facing the situation in front of him, Su Yue couldn't help but frowned and felt a little tricky.

"It seems that I have to go through the main gate of the nuclear power plant this time. It's really a bit tricky." He sighed helplessly.

There is such a high-difficulty copy, and they will set up a save point in the middle.

Then go through the shortcut door and return to the real world.

If you want to open this type of door, there is no other way unless you activate the save file in the copy.

Su Yue glanced at Lu Wei who was wolfing down food beside him, and suddenly felt hungry.

Since landing in the early morning, they have walked all the way to the nuclear power plant.

There is almost no time to stop to rest and eat.

So, Su Yue took out a Beijing roast duck and a bottle of ice beer from his bracelet.

He elegantly tore open the wrapping paper of the roast duck, picked up a piece of tender roast duck and put it in his mouth.

At the same time, he took a sip of the cold beer. This delicious enjoyment temporarily relieved his fatigue and helplessness.

Then, Su Yue took out the three legendary treasure chests.

Two of them were as a reward for his and Lu Wei's survival.

And the remaining one was the trophy just won from the leader-level alien sandworm.

"Let me see, what can be found in these three legendary treasure chests?"

The chance of getting high-level items from such legendary treasure chests is as rare as phoenix feathers and horns.

Therefore, Su Yue did not have too much expectation.

"Alas, as expected, they are all ordinary things!" Su Yue opened two treasure chests in succession without hesitation.

As he expected, none of the items inside could catch his eye.

When Su Yue's eyes finally fixed on the last treasure chest.

Golden Legend!

A long-lost, mythical consumable appeared inside.

It was a mythical [Master Key].

[Master Key]: Mythical consumable. Yokohama Locksmith, there is no lock that cannot be opened! After using it, you can open locks or mechanisms below the mythical level.

The rarity of the mythical master key is beyond words.

Its appearance often triggers countless competitions, but it is often unsalable.

After all, its wide range of applications covers almost all hidden copies within the scope of Blue Star.

Whether it is an ancient ruin hidden deep in the jungle.

Or a mysterious palace hidden in the deep sea.

Even a door to a fantasy world suspended above the sky.

As long as there are locks and mechanisms, they cannot stop the magical power of this master key.

It really is what you think, and it will come true!

With this "master key", he can break through the many obstacles brought by those barriers and freely shuttle between various secret realms.

Obviously, the door in front of Su Yue can be opened with the master key.

"Sorry, I was too loud just now!"

Su Yue's face was filled with joy, and the food in his hand was quickly swept away by him.

When his fingers touched the mysterious door again, the master key suddenly flashed a dazzling golden light.

[Ding! The front is a special area. Do you want to use the "Master Key (Mythical Level)" to force it open? Please note that once used, the master key will no longer exist. 】

Su Yue nodded without hesitation and said firmly: "Confirm to open!"

With a creaking sound, the door of the underground passage slowly opened.

A strong and pungent smell mixed with high temperature hit people's faces, making it almost impossible to breathe.

And at this moment, the Houyi Sun-shooting Bow in Su Yue's hand seemed to sense something.

It suddenly shook violently, as if telling some unknown story.

This time the reaction was stronger than any previous time.

Obviously, the place where the Yamata no Orochi is about to appear is undoubtedly here.

Su Yue took Lu Wei and stepped into this copy without hesitation.

As soon as they entered, the door behind them closed with a bang.

Su Yue looked back, and the passage door that originally led to the outside world had also disappeared in the air.

The environment they are in at the moment is a spacious cave.

There are oil lamps hanging on the walls of the cave, and they seem to be able to sense Su Yue's presence.

Every time you get close, an oil lamp will light up.

And when people leave, the oil lamp will go out.

"It seems to be here!" Mu Gui's voice sounded in the silent cave, with a hint of certainty and expectation.

At this moment, Su Yue's ears suddenly rang with a system prompt:

[Warning! Warning! The system detected that "Lone Wolf" entered the unopened dungeon area by unconventional means, and the data is being urgently readjusted. 】

This sudden news surprised Su Yue.

Even though he has rich experience and broad knowledge.

However, the term "unopened dungeon" is unheard of to him.

Could it be that this is related to the fact that Yamata no Orochi has not yet appeared in the world?

Since this is an unopened dungeon.

Then its difficulty is so high that it is probably beyond the ability of the Sakura people at this stage to cope with it.
