Because everything happening in front of him can be fast-forwarded at will, and after the same work is completed, it can be completed in batches like "copy and paste".

This is a bit like in some city construction games. To build a road, you only need to select the starting point and drag it to the end point; and as long as a certain area is circled, you can directly fill it with floor tiles.

Therefore, the step of laying floor tiles is not difficult. Although there are various different units such as railings, bridges, white marble steps, etc., it can be completed as long as you are patient.

A lot of repetitive work can be done by copying and pasting. And some specific components only need to be assembled for the first time.

Special attention needs to be paid to some of the special units, such as the previous boulder weighing more than two hundred tons with a five-clawed golden dragon carved on it, which needs to be properly placed in the center of the two rows of stone steps.

Seeing a large number of craftsmen and civilians returning these materials one by one, Li Hongyun felt an inexplicable sense of accomplishment.

During this process, Li Hongyun also saw many construction methods used by ancient craftsmen, which was an eye-opener.

But then, a more difficult challenge came.

Because he is going to start building a large palace.

There are nearly 9,000 houses in the entire Forbidden City. Among them are some small rooms for eunuchs and palace maids, but there are also some very large buildings.

For example, the largest Jinluan Hall, Fengtian Hall, has a construction area of ​​3,000 square meters and a height of more than 30 meters. It is supported by 72 huge pillars, six of which are gold-wrapped dragon pillars.

In fact, the existing Jinluan Hall is only over 2,000 square meters. This is because Fengtian Hall was often struck by lightning and destroyed by fires after it was built because it was too high. Therefore, it has been repeatedly rebuilt and repaired.

In the process of reconstruction and repair, on the one hand, it was because the national power was declining and it could no longer support such a huge project. On the other hand, it was also possible that it was worried about being struck by lightning again in the future. Therefore, during the reconstruction, both the area and height were reduced from the original ones.

.

What Li Hongyun saw at this time was the scene when Fengtian Temple was first built, so it was still in its most magnificent state.

As the layers of floor tiles are laid, the entire hall has begun to take shape.

Li Hongyun selected a few seemingly large pillars and stood them one by one on the virtual shadow of the drawing.

However, after setting it up, Li Hongyun was a little surprised.

He watched these peasants try their best to erect the huge golden nanmu pillars on the ground, but after careful observation, he found that these pillars did not go deep into the ground, but stood on the ground!

This made Li Hongyun feel very confused, and even wondered if he had missed some steps.

According to modern architectural principles, shouldn't these load-bearing pillars go deep into the ground, the deeper the better?

Because the deeper the load-bearing column, the more stable it will naturally be. Otherwise, if there is a slight earthquake or something, the load-bearing column placed directly on the ground will shake with the whole building, wouldn't it be easy to collapse?

But he looked carefully at the drawing and found that the pillar was standing on the ground and did not go deep into the ground.

With doubts, Li Hongyun continued to piece together the upper part of the pillar.

Li Hongyun still has a basic understanding of mortise and tenon and bracket structures.

The so-called mortise and tenon joint is a connection method that uses concave and convex parts on two structural parts. The protruding part is called a tenon and the recessed part is called a mortise. Some clever mortise and tenon structures do not require the use of any nails or glue.

Keep the two pieces of wood tightly together.

Moreover, this structure is not only stable, but also maintains a certain degree of flexibility and is durable.

Metal is easy to rust or oxidize, and glue is easy to lose its stickiness, so many modern furniture will fall apart within a few decades. But furniture made with mortise and tenon structure is still strong and durable even after more than a hundred years.

If the mortise and tenon are regarded as the basic units of protrusions and depressions in building blocks, then the bracket is a special structure composed of several basic units.

To put it simply, various beams are stacked layer by layer on the columns to continuously expand the stress-bearing area and finally support the roof.

Li Hongyun has seen the structure of Dougong. After all, many modern buildings also use the red Dougong shape in order to show their cultural heritage. But seeing it is one thing. It is another thing to build Dougong by yourself.

On the more than 70 huge golden nanmu pillars of Fengtian Hall, each pillar has a bracket structure, and between the brackets, various beams are connected to each other, which together support the entire roof.

The basic structure of a dougong alone uses dozens of different sizes and shapes of wood, and these structures also have names.

The game developers of "Dark Sand" mercifully only allow players to assemble relatively large structures. As for the more detailed parts, they can allow players to automatically complete them after assembling the rough structure.

But even so, Li Hongyun still felt that his head was as big as a bucket and his whole body collapsed.

"These parts...look exactly the same!"

Although there is a ghost shadow, the ghost shadow is a state that has been assembled after all. Various lines are densely packed and layered. If you want to accurately find the corresponding parts in reality through the appearance of the claws and claws that have been assembled, this is

It's definitely quite a frustrating thing.

For example, among the components, there are many kinds of "fighting", and they also have various names, such as united fighting, interactive fighting, loose fighting, etc.

But from the appearance point of view, Li Hongyun can hardly see any difference between them.

If you look carefully, you will find that they seem to be different in size. The interactive bucket is the longest, the united bucket is the second, and the scattered bucket is the shortest.

However, this difference is very small. If you take them out and compare them individually, you may be able to tell them apart. However, once they are thrown into a huge building complex, you will not be able to tell who is who.

"Forget it, let's work hard to achieve miracles!

"Anyway, the mortise and tenon joints are just one carrot and one hole. One tenon and one joint. If you insert them in, it should be enough to raise the roof."

Li Hongyun decided to leave his destiny to his own luck again and began to put it together.

Fortunately, after the first bracket structure is assembled, this structure becomes a directly accessible part and can be applied to other pillars as a whole.

Immediately afterwards, Li Hongyun began to build roofs, lay tiles, and build exterior walls on these bracket structures.

On the periphery of these huge buildings, craftsmen and civilians built tall wooden scaffolding and began to do various decoration work. For example, there is a pair of dragon kisses at both ends of the main ridge of the roof of Fengtian Temple, which is more than three meters high and two meters wide.

It weighs about four tons and is composed of 13 glazed components.

In addition, there are various complex and exquisite murals and other decorations.

There are many details like this. They are either for pure beauty, or they also have special functional uses in addition to beauty.

With the rapid enrichment of various details, a huge prototype of Fengtian Temple was initially revealed in front of Li Hongyun.

"It doesn't seem that difficult?"

Li Hongyun witnessed such a huge building gradually being completed in front of him, and a sense of pride that "this is it" arose spontaneously.

Fengtian Palace is the largest palace in the entire Forbidden City. As long as it can be built, thousands of palaces will definitely be built in the future. It is just a matter of time.

However, just when Li Hongyun wanted to enter the Fengtian Temple to take a good look at his masterpiece of building blocks, an accident happened.

The craftsmen and soldiers who were still busy in the Forbidden City all disappeared out of thin air, and then the entire ground began to rumble and tremble!

Li Hongyun was startled: "What is going on?"

He didn't have time to think too much, because the entire Fengtian Temple began to shake in the violent tremors, the tiles trembled and made a crisp collision sound, and all kinds of rubble and dust fell.

"earthquake?"

Li Hongyun quickly realized that this was probably not a real event in history. After all, he had never heard of an earthquake during the construction of the Forbidden City. It was probably a special test arranged in this trial fantasy.

"I followed the drawings, so there should be no problem...

"Bar?"

Before Li Hongyun could say the word "ba", he saw somewhere on the Fengtian Hall suddenly collapse out of thin air. Then, as if it triggered some kind of chain reaction, other brackets also collapsed one after another, along with the thick

The load-bearing column also fell to one side!

Large amounts of dust were raised.

When the dust dispersed, when Li Hongyun looked at Fengtian Hall again, he realized that the hall where he had devoted so much effort had turned into ruins.

The wood was crooked and rubble was everywhere. The originally majestic hall seemed to have been slapped by a giant from top to bottom and turned into a two-dimensional structure.

"Why is this happening..."

Li Hongyun was confused and a little confused.

Logically speaking, he put it together according to the drawings, so there shouldn't be any structural flaws, right?

Is it because the pillars did not penetrate deep into the foundation?

That's not right. This is how it is drawn on the drawing. If you take it upon yourself to drive the pillars deep into the foundation, it may cause more serious consequences.

"Could it be that those three types of fighting are used incorrectly?

"Mortise and tenon joints are about a tight fit, and there are strict requirements on size. The three types of buckets seem to have only slight differences in size. If a large-sized bucket is placed in a small position, it may not be visible on the surface.

But the gap left will definitely be larger than the one reserved in the design.

"The structures of the brackets are all copied and pasted. If there is a problem with one bracket, it means that other brackets will also have problems...

"In this case, when an earthquake strikes, the original structure will have weak points, and a chain reaction will occur, which will naturally cause the entire structure to collapse.

"It seems that at this time, we can't think about miracles with great strength. Let's just follow the drawings and put them together..."

Li Hongyun couldn't help but admire the wisdom of the ancients.

In ancient times, it was quite incredible to build such a building covering an area of ​​several thousand square meters and several stories high without using any nails or glue.

Moreover, this building must also have good shock absorption capabilities, which is even more incredible.

Many modern reinforced concrete buildings cannot withstand earthquakes, let alone ancient buildings?

Just because Li Hongyun failed to do a small detail, it triggered a chain reaction and caused extremely serious consequences.

If this were placed in ancient times, if the palace built collapsed and the emperor was buried inside, it would have to be a case of Ling Chi and the nine tribes being killed, right?

It is even more amazing that these ancient architectural masters not only built such a complex structure, but also made the various components fit together tightly and have strong earthquake resistance.

Li Hongyun continued to build the Temple of Heaven from scratch.
To be continued...
