(Thanks to the leader of "Ye Nianling" for his reward, three-in-one, the number of words is slightly less, and a big change will be added in the morning to make up for the number of words, from today onwards, be a person who does not owe more)

Cheng Mo swept away the tiles, and what appeared in front of Cheng Mo's eyes was a piece of golden bronze, even at night, it was in stark contrast to the black tiles next to him.

If a different person were here, there would be no reaction at all when he saw the bronze roof. Even if Cheng Mo hadn't read Professor Yang's book, if it weren't for his father, he would probably have studied the architecture of Qin Shi Huang's mausoleum, and he might have also ignored the past, and he would not be so surprised.

After all, bronze can be seen everywhere in the mausoleum of Qin Shi Huang, and the roof is made of bronze, which is not surprising, right? Bronze "elevators" have appeared, and the bronze roof is not at all mysterious, what is there to be surprised about?

It's just a fuss.

Even Cheng Mo, like most people, will take for granted all the "strange" things that happen around him because he is in the land of ruins, because this is the inner world.

But his father's investigation made Cheng Mo vigilant, so he had a trace of suspicion about the appearance of a metal roof above the Xiangtang, knowing that the situation in front of him did not match the description of the construction process of the Qin Dynasty buildings in the book. It stands to reason that what he saw should have been a gray gray back pressed from slag and lime, not such a shining bronze.....

For those who don't know about ancient architecture, they won't know that Huaxia has played the mortise and tenon structure to the peak, nor will they know that Huaxia architecture is based on wood frame structure as the main structural method, which is in stark contrast to the stone structure of the West.

There are many reasons why the East and the West will develop two completely opposite directions, one of which is that the Chinese people are too smart, and the ancient Chinese architects were able to make full use of the principles of mechanics to break through the limitations that wooden materials cannot support tall buildings.

Whether for the West or the East, waterproofing is a problem that must be solved in buildings.

Especially in China, the vast majority of areas are relatively rainy, the house structure is still a wooden frame structure, and if the problem of water discharge is not solved, there is no room for development of the wooden structure in China. Therefore, the waterproofing of ancient Chinese buildings is also at its peak, and it is still used by design architects from all over the world to this day.

The construction of Chinese roofs is an important part of Chinese architecture, and Cheng Mo has mentioned this in the "Ten Thousand Generations - Ancient Chinese Architectural History" that Cheng Mo is looking at today, and it can be said that the foundation and roof of Chinese architecture are born for waterproofing.

The thatched roof built by Homo sapiens from the late ancient Stone Age could not prevent leakage, let alone build a roof with a small slope and a large span, and it was necessary to create new waterproof materials to make this possible.

The birth of tile has brought great changes to the construction of houses in China, and has brought Chinese architecture into a new era. Judging from the unearthed cultural relics, tiles appeared in China as early as the Western Zhou Dynasty, and copper tiles and iron tiles were also developed, and these Europe did not appear until the 17th century.

At this moment, Cheng Mo is surrounded by a pile of black tiles carved with Benlu, Lima, Four Beasts, and Three Cranes, which are as dense as stones, and are like chimes, and the reverse side of the tiles is engraved with the small seal and number of "Zuo Si Xian Tile". Tiles are divided into slab tiles, cylinder tiles, and half-tiles. (The tile is laid on the roof, the tube tile is covered between the two rows of tiles, and the tile is the tile head of the tube tile in front of the eaves) Each tile has tile nails and tile rings to fix the position of the tile, and the tile nail and tile are still separated, which is completely different from the Qin Dynasty tile that Cheng Mo saw in the museum.

In short, it can be said that the production process of Xiangdian tiles is not outdated today.

However, this is not the focus of Cheng Mo's attention, the point is that the tiles cannot completely block the leakage, so there are supporting roof construction methods, and Cheng Mo did not take a serious look at the specific methods, but he knew that there was absolutely no roof made of bronze or bronze sheets, which was contrary to common sense.

At this moment, in front of Cheng Mo's eyes, the hanging tiles used to hang tiles above the roof are not the ancient traditional wooden hanging tiles, but the bronze hanging tiles, just this alone, it can only be said that Qin Shi Huang is rich and capricious, but if the entire roof is cast in bronze, it would be incredible......

Cheng Mo stood up from the roof full of doubts, and couldn't wait to lift the tiles of a whole inclined roof, and sure enough, the entire roof used a one-piece bronze roof, which was connected to the bronze ball at the top of the spire, which made Cheng Mo a little dumbfounded.

You must know that the fully enclosed metal coil "lead tin back" did not appear until five hundred years ago, but it was only the lead tin alloy melted and cast into a plate about one centimeter thick, welded into a whole, also known as "tin back" or "tin back", the Qin'an Hall in the Imperial Garden of the Forbidden City is the use of this waterproof technology, which is already rich enough, there is technology (metallurgical technology) willfulness, I did not expect that 2000 years ago, Huaxia built a more capricious building.

Cheng Mo stood on the spire and overlooked, through the bronze hanging tiles above, the entire bronze roof was as smooth as a mirror, and even a blurred moonlight could be seen, which was really a bit more than cognition, modern people looked at such a large area of copper and felt nothing, but in ancient times this was not an easy thing, first of all, the casting level was not high, it was difficult to control the flow of molten copper, causing the roof to be out of shape, especially if this is still a slope.

This alone will kill other civilizations of the same period.....

It's incredible.

Cheng Mo squatted down again and knocked on the bronze roof, even more unexpectedly, this is not a copper sheet, its sound is not crisp at all, it is very dull, and in an instant Cheng Mo judged that the roof is very thick, at least more than fifteen centimeters, such a heavy roof, how can the wooden structure withstand it?

You know, it's still a three-eaves building.

No wonder my father went to Professor Yang.

Cheng Mo jumped off the roof of the Xiangdian Palace, and quickly ran into the Xiangtang, inspecting the wooden columns in the room one by one, the wooden frame structure of the house, the walls are not load-bearing, all the weight of the house is concentrated on the columns through the beams, such a heavy roof, ordinary wooden columns can never support it.

Cheng Mo tapped hard a few times with his knuckles on the red-lacquered wooden pillar that surrounded the entrance of Xiangtang, listening carefully to the sound, it seemed a little weird, with the carrier's current mastery of sound waves, Cheng Mo could easily hear the two frequencies. The pitch that reached his ears first was higher, and the latter was lower, which means that the cylinder in front of him was composed of two objects, one with a low density and the other with a high density.

Remembering that the last time he was kicked by Bai Xiuxiu and leaned on the column, the column was actually tattooed and did not move, and it was a little unexpected, Cheng Mo was even more puzzled, looked around, and saw a lot of bronze swords and crossbows falling in the corridor, so he ran over and picked up a bronze sword from the ground, returned to the column, waved his hand and slashed directly towards the red lacquer column, and suddenly the bronze sword slid deeply into the wooden column.

Cheng Mo pulled out the bronze sword, chopped it a few times, sawdust splashed everywhere, and soon heard the sound of gold and iron, Cheng Mo threw the bronze sword at his feet, peeled off the thick wood, and saw that the wood was wrapped in a golden "bronze core".

Cheng Mo was stunned, it turned out that this hall of enjoyment was a traditional Chinese wooden structure on the surface, but in fact it was an out-and-out bronze hall, or a "golden hall......

————————————————————————

Cheng Mo later used a pulsed laser beam to cut through the bronze roof and explore the starting method of the bronze elevator, and sure enough, it was a winch driven by "manpower" to connect the pulley block device. Each set of elevators requires four people to push the handles and wrap the ropes around this vertical axle. There is a rope between the winch and the main crane, and this rope is wound around the main wheel over there, which is the most basic principle of the conveyor system. When the rope on the winch is wound around the big wheel, the small wheel on the axle will wrap the rope on the "cage" and pull it up......

It is not surprising to think that the Qin Dynasty could lift huge stones into such a deep underground to create this kind of "human-powered elevator", which is included in Zhang Yimou's "The Great Wall". And the reason why this system is not popular, probably because it is not necessary, except for the tomb of Qin Shi Huang, which is buried hundreds of kilometers deep buildings need this kind of elevator, other buildings really do not need to be thankless.

And these deep wells must have been filled in after the construction of the mausoleum was completed, and the reason why there was no record was also because Qin Shi Huang and Qin II killed all the craftsmen who built the mausoleum.

After figuring out what he wanted to figure out, Cheng Mo took a lot of effort to return to the fifth underground floor of the mausoleum, re-set the activation point and returned to the main body.

The discovery of the bronze hall let him know why his father would look for Professor Yang, whether for historians or anthropologists, the appearance of buildings with craftsmanship beyond the times more than 2,000 years ago is a shocking event, but it is a pity that the bronze hall only exists in the land of the ruins of the world, in reality, it should have been demolished by Xiang Yu and become his own property.

However, although the bronze hall is very magical and incredible, it is also within the scope of imagination, and it is reasonable for the Qin Dynasty to cast such exquisite bronze carriages, bronze tripods, and bronze weapons.....

In addition, Cheng Mo has always believed that the cognition of a thing is piled up by some trivial things, and the vast majority of people do not have the ability to see through the essence of things at a glance, and can only explore the path to the "root" by observing some "appearances".

Some appearances may seem insignificant and perhaps important, while others appear important but insignificant. The answers to these questions must be found in practice, not just by feelings and impressions.

During this day, Cheng Mo went to Professor Yuan Zhongyi again, consulted him a lot about the mausoleum of Qin Shi Huang, and asked Professor Yuan what books he needed to read if he wanted to understand the mausoleum of Qin Shi Huang.

However, there are not many books in China that specifically introduce the Mausoleum of Qin Shi Huang, except for a book written by Professor Yuan himself, "Archaeological Discoveries and Research of the Mausoleum of Qin Shi Huang", there are not many other books to refer to, compared to the Mausoleum of Qin Shi Huang has not been excavated, only the Qin figurines and bronzes have been written by Professor Yuan, and there is no need for others to publish a separate book, including Professor Yang, who has not published a separate book for the Mausoleum of Qin Shi Huang.

So Yuan Zhongyi recommended "The Tombs of Chinese Emperors" and "Ancient Tombs" to Cheng Mo, and gave Cheng Mo a complete version of the documentary on the Mausoleum of Qin Shi Huang filmed by CCTV, saying that many interviews were not broadcast on TV.

Cheng Mo was very grateful and said goodbye to Yuan Zhongyi, and when he left, Yuan Zhongyi told Cheng Mo that it was okay to write about tomb robbery, but remember that the property must be handed over to the state......

Cheng Mo paused for a moment, and he didn't know if Professor Yuan Zhongyi was joking or serious, so he could only nod his head and agree.

With the full version of the documentary given to him by Yuan Zhongyi, Cheng Mo went to the Drum Tower Bookstore again to replenish two books, and also bought a laptop with an optical drive, and then went back to the hotel and began to frantically supplement his knowledge of the mausoleum of Qin Shi Huang.

After watching the documentary given by Yuan Zhongyi, especially the part where the reporter interviewed Yang Hongxun, and listening to Yang Hongxun's description of the underground palace in his imagination, Cheng Mo felt more and more that things were not so simple, and a single bronze hall seemed to be just a part of this huge mausoleum.

However, Cheng Mo felt that this was just his own whimsical conjecture, his idea was too crazy and unrealistic, if it weren't for the existence of the Chosen One system, he would definitely only think it was a joke, and now he thinks that everything can only be found when he arrives in the underground palace to know if there is a trace of possibility.

Although Cheng Mo was not hopeful, he was also looking forward to the moment when he arrived at the underground palace......

—————————————————————————

Finally getting closer and closer to the day of arriving at the dungeon, the fifth and sixth layers of Cheng Mo and they brushed for two days, but when they reached the third floor, there were fewer and fewer rooms in the labyrinth, and the difficulty of each room became more and more difficult.

However, judging from the kill list, the progress of the four squads is about the same, but Jin Zihan of the first squad is far ahead, and he throws a lot of values at Du Leng, who is currently in second place.

This also cast a shadow over Cheng Mo's plan.

At this moment, the five of them completed today's monster farming plan and were about to return to the main body, but they were stopped by Guan Bojun's "all wait".

Guan Bojun saw that everyone's eyes were focused on him, and then he said, "The problem now is that there are not many monsters in the first and second layers, and if the five people are divided equally, Du Leng may not be able to catch up with Jin Zihan..... Shouldn't we figure it out?"

In fact, this question is known, but Du Leng, who is in second place, Zhu Lingqi, who is in third place, and Cheng Mo, who is in fourth place, deliberately ignored this matter, Cheng Mo and Zhu Lingqi because they didn't want to mention it, and Du Leng was inconvenient to mention it.

"Then why don't we also concentrate our resources, change the output order, put Du Leng at the end, and let him complete the kill?" But Xu Jiyun, who was ranked ninth, didn't care, compared to her own ranking and experience points, she wanted to see Gu Feifei and Jin Zihan deflated, so she said directly without hesitation.

Xu Jiyun's proposal is not difficult for Cheng Mo and them to operate, the monsters of the nine-layer labyrinth, except for the small boss, most of them are the same, and now Cheng Mo is accurate enough to know what kind of monster to use with that set of skills, and they can naturally control who is killed in the end. In the first few layers, the mobs take turns to brush.,BOSS by luck.,The distribution is still relatively even.。

Cheng Mo had to brush the maze for an hour every day, and he also relied on an extra hour to make up for the original lack of kills, so he took the initiative to say: "I have no problem, as long as you agree, I don't care." ”

However, Zhu Lingqi didn't want to, he suffered a lot more humiliation than Du Leng, and he urgently needed to prove himself with his ranking, so he shook his head, "To be honest, I don't think even if I give it to Du Leng, unless I give Du Leng all the monsters that I snatched from the first team, and then Du Leng also performed very well when he passed the Golden Man Array and fought Qin Shi Huang, then he had a chance....."

Du Leng naturally heard from Zhu Lingqi's tone that he was unwilling, although Du Leng hoped that everyone could help him win the first, he could only pretend not to care at this moment and said: "Actually, it is good to be the first, even if you don't get the first, it doesn't matter, as long as you can brush the monster of the first team and let out a bad breath." ”

But Guan Bojun wanted to completely slap Gu Feifei in the face, and said with some anger: "I'm afraid you haven't read the WeChat group! Gu Feifei has been jumping too much recently..... MD, talking is also crazy and boundless....."

Recently, Gu Feifei often joked about Guan Bojun, saying that Guan Bojun not only upgraded the tail of the crane, but was also sold by his teammates without letting go of a single fart, in addition to praising Zhu Lingqi for his courage, knowing that he could not beat him again and again, compared to others, he was too inferior.

Gu Feifei finished the people of the fourth squad at one time, and naturally the momentum of the fourth squad has been a bit fierce recently, not to mention that the 2nd, 3rd, and 4th teams are all from the fourth team, and even Guan Bojun has been promoted to the eleventh place, so he is deliberately creating contradictions.

Guan Bojun also regretted that he didn't keep his mouth shut after he was resurrected that day, and scolded Cheng Mo and Du Leng on the public screen, but now he can't explain that they are carrying out the secret plan of "robbing monsters", and he can't explain it, so he can only lie down and laugh at it.

But when a few people with a good relationship got together in private, everyone advised him not to take anything to heart, saying that Gu Feifei would take the bird virtue and let him calm down, but Guan Bojun couldn't help it anymore, and said in front of a few people: It will definitely make Gu Feifei look good, and he will definitely not let Gu Feifei win Jin Zihan to the first place if he wants to....

A few people are also used to joking, and they made fun of Guan Bojun for ruining her if he couldn't get Jin Zihan....

Unexpectedly, these jokes reached Gu Feifei's ears again, so Gu Feifei directly lashed out at Guan Bojun in the WeChat group, and directly @ him, saying that he would only put a mouth cannon behind his back, a kind of face-to-face gambling, and scolding Guan Bojun for being a dead otaku, he would be obscene, lick the screen or something, it was really disgusting.

Even Jin Zihan, who has never spoken in the group, came out to ask Guan Bojun, where did she offend him?

Although Guan Bojun wanted to stand up and say "gamble on it", and he also wanted to say to Jin Zihan very domineeringly that this was a matter between men, he also knew that he couldn't startle the snake, so he forcibly held back and didn't bubble.

watched Gu Feifei make fun of him in the group, and didn't reply a word, but Guan Bojun always held his breath in his heart, and waited for the time to rob the monster of the first team and break Gu Feifei's plan to win the first place with gold, so he laughed back.

However, if there is no plan to make Gu Feifei win the first place in gold, just rob a few monsters, then the effect of the face slap will be greatly reduced, which is not what Guan Bojun expected, so he deliberately left everyone behind and brought it up solemnly, but he didn't expect that not everyone thought like him.

Zhu Lingqi said with a cold expression: "I'm closed, I've never looked at it> Du smiled bitterly, "I saw it, but what can I say?" He didn't even make me sarcastic..... Whoever calls him strong, has a hard background, and there is a reason for others to be arrogant. ”

Xu Jiyun sneered: "Bear it, then I won't bear it, if Zhu Lingqi is unwilling to let it, I can give mine to Du Leng." ”

"Mine is also ....." Although Guan Bojun has no eye for things between men and women, he is not without emotional intelligence, seeing that Zhu Lingqi is so obvious, he immediately said to Zhu Lingqi: "Old Zhu, don't think we are forcing you, we are voluntary, mainly for Gu Feifei, not for you, I also know that you are in a bad mood after being defeated, and you are in a hurry to raise the level.... So you still follow the rules and continue to brush yours. ”

Zhu Lingqi stood aside and did not speak.

Seeing Guan Bojun and Xu Jiyun looking at him, Cheng Mo said lightly: "Mine can also be made." "He doesn't care, anyway, he can make up for the experience in an extra half an hour, so there's no need not to do this favor.....

"Then it's decided!" Guan Bojun said impatiently, with a hint of excitement on his face, as if he had seen the scene of slapping Gu Feifei in the face two days later.

Du Leng pretended to smile bitterly, "Actually...... There's really no need to let it, when we brush the monster of the first squad the day after tomorrow, I don't think we will necessarily be able to catch up. ”

"We want to make sure everything goes wrong!" Guan Bojun said quickly.

Xu Jiyun also nodded, looked at Du Leng and said, "Du Leng will rely on you this time! When the time comes to fight the Twelve Golden People and Qin Shi Huang, we will all cooperate with you, you have to come on! Don't let us down!"

Seeing that the gesture had been made, Du Leng no longer refused, nodded and said, "No problem, I won't let you down..... I've been trying to find a relationship to borrow a powerful skill recently.... C-class high-frequency electromagnetic waves.... The other party hasn't replied yet, but there should be no problem. ”

Xu Jiyun said: "You borrowed it from Xie Minyun?"

Du Leng didn't answer positively, but said with a smile: "It doesn't matter who you borrow it.....

Guan Bojun smiled "haha" and bumped Du Leng's shoulder, "It must be looking for Xie Minyun..... Don't be embarrassed to admit it....."

At this time, Cheng Mo interrupted the small talk of several people with an expressionless face, "You gossip or go back to the main body to chat, don't waste time here." ”

Everyone moved their eyes to Cheng Mo, who suddenly destroyed the atmosphere, but Cheng Mo turned around and walked directly to the maze.

"It seems that ZERO is a little unhappy? Is it because we think we forced him to let him experience?" Guan Bojun said a little inexplicably.

Du Leng lowered his hand, "No one forced him..... He himself said at the beginning that it didn't matter!"

"Maybe I really think we're delaying too much time!" Guan Bojun touched his head and said puzzled.

Only Xu Jiyun looked at Cheng Mo's back thoughtfully, and felt that Zero's mood was a little strange, not like he was angry about the experience.....

"Let's go!" Zhu Lingqi chose to return first, so the others lit up the DNA light pillar one after another.
