"I think this is it." The mage said after comparing the map for a long time.

The strong man looked around and said, "But the area of this place is not small, didn't the map say where it was?" ”

"You don't have to bring so many people to look for it." Cook said as he threw a shovel to the strong man. "Go dig around, since there is a task to save zài, there must be clues nearby."

"Hey, really. My big bear was even reduced to being a miner."

"What? Do you despise miners? Cook asked in an unkind tone.

"Hey, I didn't mean you." As he spoke, the strong man raised the shovel in his hand and said with a dry smile: "Dig a pit and dig a pit."

After the strong man and Cook started digging the pit, the mage asked the others around him to start digging the hole together. It was the first time I had seen more than 400 people digging a pit together, and although there were more people digging a trench than there are now, I had been looting materials all day long, and I had never seen a pit dug at all.

I have to say that although the methods of these Russians are a little stupid, the effect is good. It took more than two hours to dig from afternoon to evening, and the gang finally found the clue at the last moment when the sun set.

When an NPC goes down with a spade, it doesn't shovel out the rocks, but instead bounces the spade up, and there is an echo similar to the sound of metal hitting under the ground. "Team leader, there's a situation here." The NPC screamed as soon as he realized something was wrong.

After digging for more than two hours, Cook and they were already annoyed. Now, as soon as they heard that there was a situation, everyone threw their shovels and rushed to the NPC who was shouting.

"Did you find anything?"

"I don't know yet, but I didn't move the shovel just now, and it looks like it's metal underneath."

"Metal?" When the mage heard this, he hurriedly called the strong man over. "Big bear, you dig it."

"Okay." The brawny man said yes and quickly took the shovel and began to dig, but he also shoveled the metal as soon as he went down, and only after Cook reminded him to dig along the topsoil did he lift up a large area around him.

Originally, Cook thought that what they dug up would not be too big, but what they didn't expect was that as the bear cleaned up, the exposed part of the metal under the ground turned out to be part of a door panel.

"This looks like a door, huh?" Big Bear said, looking at the small area he had dug up.

"There must be a tunnel down here, and this is probably the entrance to the tunnel." The mage said, "Looks like we've found the right place." Let's go up together and dig out the entrance, quick. ”

At the mage's command, the stronger men around them began to dig in the earth, while the alright mages lit illumination to illuminate them. Thanks to the efforts of several hands-on diggers, a large part of the ground was soon opened, but the more they dug up, the more frightened they became.

Originally, the mages just thought that what they had just dug up was only a part of the gate, and everyone thought that they would soon be able to dig out the whole door and open it, but as everyone dug up, the exposed part showed that the area of the door was a bit scary. Before, they thought it was a door mainly because they found the knocker, but now they found that it was not the knocker at all, but the decoration on the door. This huge pure copper door panel is neatly inlaid with huge door knockers at intervals of one meter, just like the copper nails inlaid on the gates of ancient Chinese palaces, but the copper nails here are hung with rings.

"Is this for giants? That's too big, isn't it? Looking at the part that had been dug up, Da Xiong said in surprise: "According to this volume, this door is at least thirty meters wide."

"No, we're on the wrong side." The Master said: "Thirty meters is the height of a door panel, and Chinese doors are all double door panels, and the door height is generally slightly shorter than the width. This door panel should be thirty meters high, and the width of a single door panel should not be less than forty meters, otherwise it will not conform to the architectural habits of the Chinese. ”

"Isn't this gate more than eighty meters wide?" Big Bear asked in surprise.

"Not necessarily." Cook said: "Although the building habits usually don't change much, after all, this thing is a thousand-year-old thing, and who knows what specifications it was made to?" But one thing is for sure, this one is definitely not that small. ”

In fact, as Cook said, the door was indeed not much smaller, and after they cleared it completely, they realized that it was not built the way they imagined it to be. In fact, the door is neither open horizontally nor vertically, but in four directions. It was confirmed that the whole door was composed of four door panels, and the middle door gap happened to be an H-shaped lying horizontally, and this door was not an ordinary opening and closing door panel, but a telescopic one. At the bottom of the gate is a 100-meter-wide and 30-meter-high panel, which opens downwards rather than inwards or slides side-to-side. On top of this bottom door panel are two door panels 50 meters wide and 30 meters high. Combined, these two panels are identical to the one below, but they are made up of two panels and open in a way that slides open in both directions. As for the top panel of the door, its structure is exactly the same as that of the bottom one, except that it opens upwards.

The four panels were a rectangular gate 100 meters wide and 90 meters high, but it was not erected on the ground, but inclined at an angle of 30 degrees according to the slope and water level of the hill on which it was located, and covered with a layer of soil and rock. The previous NPC dug up to the top of the door, which is the thinnest layer of soil, so after digging two shovels, it touched the door panel, and the bottom of the door below was almost buried more than two meters deep, if it weren't for the upper door panel extending all the way, it would be really difficult to find it from the bottom of the door.

In order to dig out the gate completely, Cook and the others dug from the time the sun went down until about ten o'clock in the evening, thanks to the fact that there were more of them. Otherwise, it would not be so easy to dig such a large door completely.

After finally opening the door completely, the mage immediately took the map and searched for it, and finally he found a small hole in the middle of the top of the door. The hole, which could not even fit a human arm, was so small for the size of the entire door that it would not be noticeable without noticing.

As soon as the mage found the hole, he rolled up the map in his hand and turned it into a scroll, then looked down and shoved it into the hole. When the scroll was completely submerged in the hole, there was only a sound of metal striking, and the brass rings hanging from the copper nails on the entire gate suddenly stood up en masse.

"Okay, the gate has been activated, and now it's a matter of unlocking." The mage stood up and said.

"Don't tell me that this is a combination lock." Looking at the brass rings that stood up, Cook said with a bitter expression. However, as much as he did not want it, the mage told him an answer that he did not want to hear.

"That's right, this is a combination lock, but a three-dimensional combination lock, which is much more difficult than opening a safe." As he spoke, the mage pointed to the rings and said, "These rings are all standing up now, but we can manually tilt them up ninety degrees, or downwards ninety degrees, or we can twist the rings to rotate the nails under the rings at an angle. There are also those copper rings that also have scales, and turning the copper rings to change the scale displayed on the connection point with the copper nail is also part of the password. ”

Big Bear looked at one of the rings and exclaimed, "I'm X, isn't it?" The upper, middle and lower three angles of the knocker are equal to three possibilities, and the rotation angle of the copper nail has six gears, and the combination of the two is 3 times 6 equals 18 possibilities. The copper ring itself also has a circle of 36 scales, which corresponds to the previous 18 types and may form a total of 648 combinations. There are 648 combinations of this copper nail, and there are a total of 89 by 99 copper nails on this entire door, even if this door does not need to rotate the mechanism in order, these 8811 copper nails alone can combine more than 5.7 million combinations, even if we don't do anything, don't expect to open this door if we try it here for a lifetime."

"It's not a quilt, even if it's a thousand lifetimes, you don't want to count on it." The mage said, "Because this door requires a copper ring to be turned in order, and the order is still crossed, it is useless to turn from which side to which side in one order. ”

"Such a complicated lock? So how do we open it? ”

With a smug smile, the mage took out another roll of bamboo slips from his body, and then let the two NPCs fully unfold it and smiled, "In complex locks, having a password is not a problem. ”

"Damn, you don't say it sooner if you have a password, I thought I'd have to try them one by one."

Cook said beside him: "If I really don't have a password, I won't try one by one, I might as well blow the door open quickly when I have the time." ”

"You can't blow it up." The mage said: "There is a protective circle attached to this door, and brute-force cracking requires the cooperation of three main gods and above to have any hope. We can't break it. If there is an eternal sword of the purple sun, you can consider it, I heard that there is a cutting law on that thing, which can cut off a qiē thing. ”

"Damn, his sword itself is worth a treasure trove, and there is no need to open this door with that thing." Big Bear urged: "You better read the password quickly, and I'll open the door." ”

"Don't worry, this door can't be opened by one person. Wait until I'll get the people lined up first. ”

The platoon that the mage said was to let 200 people stand on the door, and then instruct them to guard a few copper nails around them before obeying the order to turn the copper ring. Although there are more than 8,000 rings on this door, most of them are useless, and only a thousand of them are needed to open the door, and each person needs to turn five rings on average, so that the workload can be smaller, and because some rings need to be rotated at the same time, and some have interval time limits, so you can't open the door even if you know the password by one or two people alone.

After everyone was standing, the mage stood in the distance, holding a loudspeaker, and shouted according to the codebook, "Teucer, go ahead, and grab the ring on your left." Harvis, down a square, yes, it's the ring, grab it. I'll count one, two, three, you two for me to press down the ring to the level of the door panel, the door knocker should lock automatically, and when the rotation is complete, Harveys you have to turn the copper nail under the ring two squares clockwise, and you will stand up as soon as you finish the turn. Teucer, as soon as you see Harvey standing up, you immediately adjust the scale of the ring in your hand to eighteen, forward and reverse can do it, but you only have five seconds, and all the knockers will automatically return to the initial state after the timeout, and the front one will be completely white. That Locker, pay attention to the ring at your feet, yes, that's it. As soon as Teucer finishes turning, you have to push the ring up parallel to the door panel, quickly turn the scale on the ring to thirty, and then stand up and shout to Harvey that you're done. Harveys, you see Lockell signaling and immediately restore the ring you just turned to a zero-scale state, and then push the brass ring back up and make it stand up. Only you have to run as fast as you can to the ring that is spaced one by one on your right, then push it upwards and shout out to Sù Sivi. Sivi, when you hear it, you ......."

The mage instructed these players step by step, and it took nearly an hour to explain the order, but it may be that the action is too complicated, and it requires the linkage of two hundred people, and this error rate is really high. Even though they knew the order, they still tried more than ten times in a row and failed to open the door, and every time someone made a mistake, all the previous steps would be zeroed, and the complexity was simply perverted.

At first, when someone made a mistake, the mage could still hold a loudspeaker and call people around to correct the mistake, but later he even shouted hoarse, and the more than 200 people were also dizzy one by one. Big Bear complained beside him: "I shouldn't have agreed to the detachment if I knew it, otherwise we would have a thousand people standing up, each responsible for a knocker, so that the steps would be much easier." ”

"You're thinking beautifully, even if we don't have a team, we will have to reduce the number of people by at least a few hundred before passing through the forest, but more people can indeed be much faster." As he spoke, the mage sent all the remaining men as well. Before, he only sent 200 people because he thought it was a good arrangement, but he didn't expect that he underestimated the unexpected difference rate caused by the large number of people, so he didn't complete it until now.

After sending all the people who were still present into battle, each of the more than 400 people only needed to be responsible for two or three rings, which was much easier for everyone. Even so, it took them five more times to get the right step. When the last person successfully turned the copper ring, he heard a bang, and the gap in the middle of the gate suddenly popped open, and then the four gates began to rumble and slide in all directions.

"Come down, come down" Seeing that the gate finally moved, the mage hurriedly shouted excitedly in his hoarse voice. But even if he didn't scream, these people wouldn't stand still stupidly, after all, the vibration was very obvious when the door was opened, and the fool would stand there in a daze.

As the door slowly slid open, a puff of purple smoke rose from inside the door and quickly spread out in all directions. Cook screamed at the sight of the color of the gas. "Stand back and cover your noses, there might be something wrong with this smoke."

I don't know if there was no problem with the smoke itself, or if Cook shouted it more timely, but after ten minutes, when the smoke completely dispersed, no one among the Russians fell.

"Looks like it should be fine, let's go in now, shall we?" One player said to the three of them, Mage and Cook.

Okumamoto came with the intention of going in immediately, but before he could speak, the mage preemptively said, "No, pay attention now." The NPC troops immediately set up a defensive line to guard it. The player divided me into two batches to eat and go to the toilet, and then came back to camp here to recover my fatigue, and we waited until tonight to explore the underground passage. ”

In fact, making such a decision, the mage himself has no choice. They have worked so hard to find this place, and now they can complete the task by going in and exploring it, and who doesn't want to go in and complete the task right away? But the mage can't decide like this, he has to forcibly suppress his ** and let everyone go offline to rest first. After all, the original plan was that they should have entered this underground passage last night, but due to many accidents, they have been tossing until now. The sun hasn't risen yet, but it's not far from sunrise. In other words, these people have been online for more than sixteen hours in a row, and there will definitely be various dangers waiting for them after entering the underground passage. In the event that someone is forcibly kicked out of the game during a battle due to real-life physical fatigue, it will not be cost-effective. So even though he knew that waiting here for one more day would be dangerous, the mage still gave the order for everyone to rest. As for why you would want to camp in the game instead of sleeping in real life. Although the camping state is sleeping, the person is still online, and the NPC in charge of vigilance can wake them up at any time if they find out about the situation. Second, the assisted sleep system of "Zero" itself is better than the sleep effect in reality, even if camping in the wild cannot achieve the same good effect as sleeping in the city, it is still much better than sleeping in reality.

Standing on a mountain peak in the distance, I saw the Russians building a camp, and I immediately understood what they were up to. After all, I've been following them for more than 12 hours, people like me don't need to sleep, it's okay to be online for a long time, they are ordinary people, and they must have reached the physiological cordon long ago if they didn't go offline for such a long time. It is estimated that if they don't sleep again, at least half of this group will have to be forcibly kicked offline by the system within an hour.

Originally, seeing that this group of people was starting to prepare for camping, I planned to sneak into the underground passage before them while they were sleeping, after all, that thing has such a complicated lock, and it must not contain ordinary things. Before I could act, though, I spotted a sneaky group of Russians cautiously approaching the camp.
