But it can be basically concluded that this is the mechanism, and the use of this method is very consistent with the modern way of opening the safe in an emergency. However, even the person who built this stone chamber had to prepare two extended keys and know the rules.

In this respect, it is also unique, otherwise it would be impossible for those who strayed into this place to open these two doors without special extension equipment.

After Nangong Yue turned the button counterclockwise, the door immediately creaked.

Without waiting for a message, Nangong Yue immediately ran out, jumped on Mai Xiaoji's palm, and then jumped down from it!

"Xiaoyue!" Mai Xiaoji broke out in a cold sweat, but Nangong Yue in the air had already changed the size of the cost, and made a victory gesture with a smile, "Hehe, am I also proficient in mastering mobile phones now?"

"I'm scared to death, don't try this kind of thing in the future, if you don't change back, you won't fall to your death if you jump off my hand?"

"Hmph, when you put away the submarine and then teleported, I'm much more worried than you. Nangong Yue pouted, and Mai Xiaoji smiled and hugged her shoulder.

"If you have anything to say, the door is open!" Zuo Ci said happily.

Yes, the door was opening inward, very slowly, and Mai Xiaoji hurriedly ordered everyone to dodge to the side and not face it.

Bang Dang!

A boulder fell from above the gate, smashing a hole in the ground.

At this moment, if someone happens to enter, they will definitely be smashed to the head and bleed, and they will die on the spot.

"Thankfully, I didn't get in by teleporting. Mai Xiaoji said depressedly.

"It's in disrepair, it's just a normal collapse. Guan Yu saw the clue.

Ban Chao carefully went over and picked up a few stones and threw them inside, the sound of the stones falling to the ground came, and no hidden weapon was suddenly launched.

Mai Xiaoji breathed a sigh of relief and was about to enter, Zuo Ci also picked up a stone and threw it over, but he was a little short of it, he didn't get in, but it happened to hit a door.

Boom!

This was followed by a series of clanging explosions, visible to the naked eye, with many bumps on the gate and even a few metal arrows exposed.

It's dangerous!

Mai Xiaoji's forehead was sweating, but it was conceivable that Zuo Ci accidentally hit and triggered the mechanism, otherwise, he would definitely be pierced by these arrows and die miserably.

"Hehe, I knew there was a mystery in this door. ”

Zuo Ci put gold on his face, and threw stones at another door, but the result was the same, the gate was attacked again, this time it was even more excessive, and there was an arrow that pierced directly and landed on the ground in front of him.

After so long, the arrow was still very sharp, unexpectedly, Guan Yu took a step forward, put on gloves, picked up the arrow, weighed it in his hand, it was very heavy, and speculated: "When it was built, it may contain gold." ”

In terms of corrosion resistance, gold naturally surpasses steel, and Mai Xiaoji took out his mobile phone to collect the gold circle, and he really collected fifty grams of gold.

The weight became a lot lighter, and it was thrown out by Guan Yu again, pierced on the gate, this time, there was no more sound, and the mechanism should have been released.

Mai Xiaoji cautiously approached the gate and collected again, and the arrows inserted in the two gates actually collected five kilograms of gold, which can be described as an unexpected joy.

Something even more unexpected happened right in front of my eyes, the gate made a clattering and cracking sound, it was literally torn apart, and it collapsed with a bang, turning into two piles of black stones.

There are some steel-like things exposed, which were used to set the opening mechanism, and at that time, it was considered a very advanced technology.

"It's not enough for a punch. Xiang Yu sneered.

"Fight, fight, fight, fight, your fist fell, ten thousand arrows pierced your heart, and we have to bury you!" Zuo Ci said, but he shuddered, remembering that he had died like this once, and he was very faceless.

It's worth trying again!

The generals threw some more stones into it, and after making sure that there was no danger, everyone went inside. Of course, Mai Xiaoji is always ready to go against the clock, which is the last guarantee to escape death.

In this stone room, there is nothing to gain, Mai Xiaoji uses a perspective shot, but he finds that the mechanism settings inside are very ingenious. The photos must be saved and can be provided to Yu Wenkai for reference in the future.

After passing through the stone room, there was another road, and after walking for a long time, a red light appeared in front of me.

At the same time, I also felt the scorching breath, and when I passed through the passage, the scene in front of me stunned everyone on the spot, dumbfounded and speechless.

There was a deep ditch in front of it, about 100 meters wide, the length was unclear, and under the deep ditch, there was actually hot magma.

Is this a volcano? Who would be perverted enough to hide a treasure in a place like this?

A stone bridge, across the deep ditch, is the only way to the other side, and in the middle of the stone bridge, there are two stones missing, as if it has become a broken bridge, but also a dangerous bridge.

"Xiao Ji, if this falls, there will be no bones left. Nangong Yue said in shock.

"Isn't there a bridge!" Zuo Ci pretended not to care, took a few steps forward, was smoked in the face by the heat, and hurriedly retreated.

"Wait here, I'll rush over first, as long as one person passes, the rest can teleport!" Ban Chao said proudly.

"Dingyuan Hou, I'll go first. Wang Dayuan scrambled.

"Dayuan is in charge of driving, you can't be without you on the sea, it's still me!" Guan Yu slapped his chest loudly.

"I'm here to break off. "Xiang Yu didn't compete for the lead this time, he was the biggest and weighest, I was afraid that if he crossed first, the stone bridge would collapse.

Just as the four of them were scrambling, whoosh, a white figure flashed quickly, Mai Dao Chang had already jumped onto the stone bridge, leaving a beautiful white line in the air, only one more jump at the break in the middle, and by the time Mai Xiaoji reacted, he had reached the opposite bank steadily.

"Beautiful, handsome!" Mai Xiaoji was happy and gave a thumbs up.

"Wait a minute!"

Zuo Cizhi frowned, and came to assist before going to the bridge, in order to be faster than Mai Dao, and in the blink of an eye, he also reached the other side, and waved proudly to this side.

Despite the light movements of both of them, there were still stones falling from the bridge, sinking into the magma and disappearing completely, without even a bubble coming out.

The road to take, not a single step, Mai Xiaoji did not choose to escape, but bravely faced it.

"I, I can't do it, I'm going to fall, I can't even find the ashes!" Nangong Yue screamed, her legs were so frightened that she didn't dare to board the stone bridge at all, Mai Xiaoji dragged her two steps, struggling and screaming, just afraid that after going up, she would delay time, and the stone bridge would not be able to bear it.

In desperation, I had to shrink her into a villain and put it in my pocket.
