The moment he pushed the door open, Qiao Guang already felt the yin qi seeping into the place.

Shen Xiaoxiao ignored Qiao Guang's dissuasion, recklessly broke in, and almost suffered a big loss, but fortunately, the foundation of Jindan's mid-term was there, and he avoided it dangerously.

The sarcophagus erected by the wall slammed open, and the coffin door slammed to the ground, whipping up heavy dust.

Qiao Guang and Shen Xiaoxiao walked together, the two stood back to back, and at this time Shen Xiaoxiao had also taken out his sword, staring at the opposite ghoul with sharp eyes.

"These things...... I haven't seen it before. ”

Qiao Guang swallowed his saliva, this large group of skeleton legions, I don't know what the strength is, anyway, it looks quite terrifying.

One by one, they also raised heavy swords and carried ancient battle axes, and their momentum was overwhelming.

"That's because you robbed fewer tombs before, if you go to Tailing in the future, there will be more opportunities to see this thing. ”

Shen Xiaoxiao licked his lips, and his body burned with fierce fighting intent.

"Listen to your tone, you used to rob tombs often?" Qiao Guang was stunned.

"Ah, I started with this before, but then I came to the Fulu Sect, and I rarely did this kind of business. ”

Shen Xiaoxiao said it unabashedly.

"These ghouls survive on yin qi, the strength of a single individual is not strong, it can be said that it is very weak for us, the terrible thing is that they are like endless, as long as the source is not eliminated, it will continue to be generated, and people can be exhausted to death. ”

Shen Xiaoxiao was recalling his previous experience, and by the way, he handed a sword forward, and it was extremely simple to smash a large area of ghouls into ashes.

"Even if an ordinary martial arts adventurer comes to these places, he can beat two or three ghouls, but if he can't find the source, he will all be eaten in the end without exception. ”

"We, but what a huge tonic in their eyes!"

After that, Shen Xiaoxiao disappeared in a flash, rushed into the group of ghouls, and danced wildly with swords, and the sword light bloomed like petals on the land, forcing the tide of ghouls back in a few strokes.

"Hurry, hurry up!"

Shen Xiaoxiao shouted loudly, Qiao Guang responded, and hurriedly rushed over, following Shen Xiaoxiao's pace.

Now that he has met an expert, he doesn't need Qiao Guang to bother.

"The door not far in front should be the exit, the key you copied should be used there, hurry up, I'll hold it here!"

Shen Xiaoxiao's figure suddenly fell, his instep was bent like an eagle's claw, tightly clasping the surface, and his upper body fell backwards completely, galloping forward in a strange posture.

Along the way, the left and right hands rotated the hilt of the sword, handing out one sword after another in a dashing manner, the sword light came and went, but in just a few breaths, the ghouls around Qiao Guang and them all disappeared, turning into piles of useless skeletons on the ground, and then gradually scattered into ashes.

And these ashes are the basis for the continuous production of ghouls.

As long as there is a supply of energy, the ashes can be reshaped, and after a certain amount of time, new ghouls are formed again.

If you stay here, it's hard not to be consumed.

Qiao Guang recognized this, and also understood the reason why Shen Xiaoxiao made such a move, he was using all means to save energy, the yin qi here is heavy, the aura is thin, if you often use a wide range of attacks, the aura will soon be exhausted.

Fighting endlessly is nothing but self-destruction.

Soon, taking advantage of Shen Xiaoxiao's outbreak, Qiao Guang successfully came to the door.

It does have a keyhole.

But on top of the keyhole, what are those circles with strange patterns printed on them?

What's that?

It seems that there are several large dark gold turntables here, and the patterns carved on them are different, but Qiao Guang can't understand what it means.

He looked back, and soon the ghouls were gathering again, and the skeletons and ashes on the ground had already disappeared.

The next wave of ghouls is coming!

After the outbreak just now, Shen Xiaoxiao became more cautious, his face gradually became solemn, he didn't expect the ghouls in this place to recover so quickly, even better than the ancient monuments he had entered before.

"Qiao Guang! speed up!" Shen Xiaoxiao's eyes were awe-inspiring, his expression was full of excitement that could not be concealed, and he shouted, "I met something good this time, I have such a big vitality charge, I'm afraid that if I don't succeed, I will become a benevolent!"

"Good!"

Qiao Guang gritted his teeth, and he didn't care about carefully pondering the meaning of the patterns above again, although he had a faint feeling that these patterns had a lot to do with unlocking, but time didn't allow it, so he could only try it first!

He inserted the key in and twisted it without hesitation!

Click!

Qiao Guang was shocked, pulled out the key and quickly retreated, two flames erupted from the original position, and the breath was scorching and terrifying, as if the air was about to be melted out of a big hole!

"Shhh...... What's going on?"

Qiao Guang gasped, the danger came suddenly just now, the golden puppet battle armor was draped on its own, and the big joints of his arms were golden and burned to some places by the flames, but fortunately all of them were blocked by the golden puppet battle armor.

The armor was hot and hot, and the heat was red, and Qiao Guang hurriedly hit two clear water tricks to cool down.

"What just happened? Are you alright?"

Seeing that there was an emergency situation on Qiao Guang's side, Shen Xiaoxiao was taken aback, and burst out with all his strength and slashed horizontally, the sword light was like a line between the sea and the sky, and the ghouls in front of him fell in pieces.

When this sword went down, only a few ruined ghouls could still stand trembling, as if they were about to fall down in the next moment, which showed the great power of Shen Xiaoxiao's sword.

"Are you alright?!"

Shen Xiaoxiao jumped back, instantly came to Qiao Guang, and asked with concern.

Qiao Guang's heart warmed, and he took out some pills given by Yu Bao from the storage ring, handed them over, and said, "It's no big deal, these are some pills that can restore aura, it's better than nothing." ”

"Good. ”

Shen Xiaoxiao was also polite, this was a fateful thing, and he didn't dare to be careless for a moment, so he took it.

"There are so many strange patterns printed on that door, and I haven't seen any mystery hidden there. ”

Qiao Guang told Shen Xiaoxiao what he had just seen, and Shen Xiaoxiao followed him to the door and observed carefully.

He tried to press his hand on one of the patterns, and Qiao Guang instantly became vigilant, in case something suddenly appeared and hurt Shen Xiaoxiao.

Shen Xiaoxiao frowned, and his right hand pressing on the stone suddenly exerted force left and right, only to hear a dull "click", and the stone actually turned!

Shen Xiaoxiao was overjoyed, his courage was enlarged, and he made more efforts again, and the strange pattern went down and fell into the hole, and at the same time, a new pattern came out!

"Is this really a turntable-like thing?"

Qiao Guang was stunned, he was surprised to see this kind of thing for the first time.

He paid attention to Shen Xiaoxiao's expression beside him, and was a little surprised, but he quickly recovered, Qiao Guang couldn't help but sigh, he deserved to be a man who used to rob tombs often!

If you count the keyhole as the innermost, there are seven floors from the inside to the outside, and the top floor is directly attached to the ceiling, so you have to jump up slightly to reach it.

After passing one of them, Shen Xiaoxiao tried the others as usual, and found that each layer had a certain number of patterns, and they increased layer by layer, and there was only one pattern in the innermost layer, not a turntable like the others, that is to say, the pattern of the first layer had been decided.

Outside there are two patterns on the second floor, three on the third floor, and so on, and seven strange patterns on the seventh floor.

Qiao Guang even wondered if these were patterns, or just some strange stripes, many of which he couldn't name at all, but just looked like some kind of fierce beast, with the shape of a beast, but he had never seen them before.

Some of the patterns between the layers are repeated, and some are completely unseen, Qiao Guang probably observed, some fierce beasts only appeared once, and some had almost every layer.

It looks like a mess, and I can't figure it out at all.

"Even if you use the exhaustive method, you can't exhaustively enumerate it in a short period of time...... And that's a lot of possibilities!"

The factorial of seven, that is, if not ruled out by any clues, there are five thousand and forty possibilities.

It is almost impossible to successfully open a door with just a few inspections.

And before you know it, the number of ghouls has increased again.

There was a knocking sound behind him, Shen Xiaoxiao was startled, looked back, and another sword was handed out, and the ghoul who rushed over with a heavy sword fell to the ground, and the skeleton still rushed forward by inertia and rolled to Shen Xiaoxiao's feet.

Shen Xiaoxiao was secretly frightened and said, "When did these ghost things learn to run?"

Qiao Guang chuckled in his heart, and had a bad premonition: "Wouldn't they run just now? Could it be because you wiped them out before, and then they jumped out even more powerfully?"

Shen Xiaoxiao saw that there were still a few more who could gather momentum to rush over, and after slashing out a few more swords to kill them, he shook his head and said: "These ghouls are equivalent to the guards of the core treasures inside, and only when they feel that the treasures are threatened, can they evolve." ”

"That is, it's not because of my attacks that they get stronger, it's because of ......"

Shen Xiaoxiao looked at the key in Qiao Guang's hand and said, "Because of it." ”

"Every time the lock is unlocked, the trap will be triggered, making these ghouls even more powerful!"

After listening, Qiao Guang was dumbfounded, what kind of intelligent protection mechanism is this?

At this time, how could Shen Xiaoxiao still have the same appearance as before? He looked at this group of unfinished ghouls with a solemn face, and now there are still a few ghouls who can speed up, and most of them are still stunned.

But even if it is, it's very serious.

Shen Xiaoxiao deliberately observed the door where they came in just now, and found that a new formation had been generated there, black and dark, deep and deep, if they didn't break the formation again, they could only be trapped inside and couldn't get out.

So, now this door is the only way for them to go, and they can only go all the way forward, and there is no way to go back. If you want to break this door, trial and error are indispensable, and it is almost impossible to find all the clues at once and then unlock this kind of lock.

Because many times, the reason why there is this kind of lock is not so that you can open it, but to stop you, so it is not certain whether you can find clues in this place.

With each mistake, the ghoul gets stronger, so how far can it go?

Shen Xiaoxiao's eyes were jumping with excited fireworks, and the belligerent factors in his whole body were about to burn.

It's a big gamble of life.

The stakes are big, and the prizes are only more enticing.
