PS: The first is to ask for a monthly pass, please support it.

The courtyard was very quiet, and when everyone walked in, they also subconsciously slowed down. A moment later, after walking through a tree-lined path, a wide doorway appeared in front of me.

Seeing this situation, Wang Guan and the others also knew that it was the place of Hou Lao's research institution. At this moment, they were more or less excited, and walked up the steps more lightly, going deeper into it step by step.

Once you enter the doorway, there is a long passage. Since there are lights every few meters, everyone can see very clearly, but on both sides of the passage are rooms with closed doors.

However, Hou Lao did not mean to stop, and continued to lead everyone to the interior, and soon after, everyone immediately saw that a huge space suddenly opened up in front of them. It was a hall the size of half a football field, with a high ceiling, and you could look up at the sky through the glass cover.

At this time, the sun is shining, and even if the lights are not turned on, everyone has enough light to see the situation in the hall clearly. But just one glance, everyone was stunned, and then they couldn't help but be excited and excited. Because in the huge space, there are many objects placed in a staggered manner. These objects vary in size and volume, but all of them are mechanical.

"That's right, it's what I imagined." At this time, Yu Feibai's face was full of excitement, if it weren't for Hou Lao still in front, it is estimated that he would have sprinted directly to the hall.

"Then take two steps faster...... Hou Lao also understood everyone's mood, and after smiling lightly, three steps turned into two steps and led them into the hall.

Immersively, everyone saw more clearly, only to feel dazzled. Look to the east, look to the west. I want to take a closer look at each item, but I don't want to miss out on anything else, so I can't wait to have a few more pairs of eyes.

"What a tall machine."

At the same time, Yu Feibai stood under a thing, raised his head and stretched out his hand to compare, and found that this thing was at least two or three times taller than himself, nearly two stories high. The most important thing is that it is relatively large, made of several large wooden columns, with some wheels at the bottom and something similar to a shed at the top.

"What is this? What does it do? ”

If you don't understand, just ask, Yu Feibai immediately asked Hou Lao for advice.

"This is a building car, also called a nest car." Hou Lao explained: "It is a lookout car specially used to observe the enemy's situation in ancient times, and the bottom of the car is equipped with wheels that can be pushed. The scaffolding above is the view of the building. The outside is covered with raw cowhide to prevent the enemy from destroying it with bows and arrows. There can be two people inside. And then condescendingly. Inspect the enemy. ”

"Oh, I've heard of it, but it's the first time I've seen a real thing." The others suddenly realized and gathered around to watch.

"This is a small and medium-sized building, used to watch the small city."

At this time, Hou Lao smiled and said: "According to the records of literature and history. At the end of the Western Han Dynasty, Wang Mang built a large nest car more than ten zhang high to observe the dynamics of the defenders in the city. It was so high that you could almost touch the clouds. Therefore, it is also called a cloud car. ”

"You see, there is a rotating shaft underneath, and when necessary, you can rotate to observe the surrounding situation, and the field of vision is more open. If you notice anything, you can report it with a simple flag......"

After signaling, Hou Lao also sighed a little: "This is an ancient war tool, and later on the basis of the building car manufacturing, it was modified into a ladder as a siege tool." ”

"Of course, when it comes to siege weapons, trebuchets must be indispensable......"

At this time, under the guidance of Hou Lao, everyone appreciated the true form of ancient war tools one by one, which is not as weak as the TV series, but it is not as exaggerated as the movie.

In addition to building cars and trebuchets, there are also trench filling cars, rushing cars, spilling cars, crash cars, goose falcon cars, dust trucks, and so on. Anyway, only you can't think of it, and there is no tool that the ancients couldn't do.

These tools are either simple or complex, and they are all relatively common things in ancient warfare anyway. Whether it is attacking cities and plundering land, or camping and camping, it can come in handy.

In some TV dramas, you can always see a group of people holding swords, bows and arrows, and even riding horses to a city. That's not a siege, it's a search for death.

However, in some movies, it is often thousands of troops and horses, pushing complex machinery more than a dozen stories high to attack the city, which is slightly exaggerated. Especially the so-called bed crossbow, separated by hundreds of meters, can directly penetrate the thick steel city gate, which is definitely a movie effect, and it is definitely impossible to do in real life.

I looked at the side and sighed, but before I knew it, I had finished visiting the items in the hall.

At this moment, Yu Feibai frowned: "No. ”

"What's wrong?" Hou Lao asked with a smile.

"Old Hou, we seem to have been fooled by you." Yu Feibai hesitated: "We are here to visit the magical mechanisms you mentioned, but not to observe the ancient tools of war." ”

"Aren't these tools mechanisms?" Hou Lao asked rhetorically.

"Ugh!"

Yu Feibai was speechless, he was unwilling to say yes, he said no, these war tools are really organs. Strictly speaking, Hou Lao really didn't lie, and these war-related tools can also be regarded as relatively magical organs.

"Organs are definitely institutions, but these institutions are props for visitors to visit."

After looking left and right, Yu Feibai said bluntly: "Old Hou, these things should be used to hide people's ears and eyes, and the secret weapons that really need to be kept secret and should not be disclosed to the public are definitely not here." ”

Hearing this, Wang Guan and Fang Mingsheng next to him thought so. They are not stupid, and they also reacted when Yu Feibai doubted, although the war tools in this hall are also considered organs, they are very different from the mechanisms described by Hou Lao before, and they are not even as wonderful as the mechanism boxes.

Moreover, it can also be seen from the layout of the objects in the hall, maybe Yu Feibai is really right, this is equivalent to a museum (exhibition hall) of ancient war tools, which refers to organizing students and tourists to visit and study from time to time, so it is a little inconsistent with Hou Lao's words that need to be kept secret.

"Haha, I only see it now."

At this time, Hou Lao didn't mean to deny it, but just smiled: "I have brought you in, but you have not found a way, so you can't blame me." ”

"Doorway?"

When Yu Feibai heard this, he immediately became vigilant and said, "Old Hou, shouldn't you let us find some kind of door by ourselves?" ”

"Almost." Hou Lao smiled: "There is no problem with taking you to visit here, but if you go deeper, it will involve the terms of confidentiality." Of course, I can guarantee that you will not leak secrets, but you still have to show some skill to get other people's approval and allow you to visit freely. ”

"I can give you a reminder."

While speaking, Hou Laoshun pointed to the side wall in the hall and said with a smile: "The door is there, and there is no need for a fingerprint password, as long as you find the switch and press it, the door will naturally open......

"How can you do this, this is obviously deliberately making things difficult."

Having said that, Yu Feibai was the first person to run to the wall, and while complaining, he reached out and felt around the wall, looking for traces such as cracks in the mechanism. However, he was disappointed by the fact that the whole wall was snow-white, which was painted with lime cement, and there were no traces of openings, let alone cracks.

Seeing this, Yu Feibai frowned, and immediately turned around and beckoned: "Eh, don't just look at the two of you, hurry up and come over to help find it." ”

"I think ......" At this time, Fang Mingsheng walked over, his eyes revealing a shrewd look: "The door is here, but the activated mechanism may not be on the wall." ”

"Sounds reasonable." Yu Feibai pondered, immediately took a few steps back, and began to look at the surrounding situation with a macroscopic gaze, especially paying attention to nearby tools. Maybe in one of the tools, there is a hidden mechanism to open the door.

"You guys just like to overcomplicate things."

At the same time, Wang Guan didn't want to drag the mud and water, so he chose to cheat without hesitation, and after knowing the mystery, he immediately came confidently. However, instead of going to the wall, he stopped three or four meters away from the wall and looked down at the floor.

Speaking of which, the floor of the hall is very exquisite, it is paved with smooth and painted wooden boards, and it is often cleaned and mopped, and it looks very clean and spotless.

"Wait......"

At the right time, Yu Feibai reacted, and said with a flash of inspiration: "You mean, the door is not on the wall, but in the floor?" ”

"That's a matter of course."

Wang Guan looked like he was holding a wisdom bead on his face: "You don't want to think about it, a snow-white wall, and there are no decorations hanging, let alone a counter or anything like that, if there is really a mechanism, how can there be no trace at all?" The most important thing is that Hou Lao just said that there is a door here, but he didn't say that the door is not on the wall. ”

"Seems to be the same."

Yu Feibai looked back and instantly caught a look of surprise in Hou Lao's eyes. In an instant, he was sure of it, and suddenly smiled heartily and said: "Wang Guan, there is your ......"

Determine the location of the door, the next thing is much easier, and there is no need for Wang Guan to go out of the horse, Yu Feibai lowered his head and observed carefully, and after a while, he noticed that there were traces of two wooden planks in the floor. Compared to the others, these two planks are shinier and show slight signs of wear.

"Hey, hey!"

At this moment, Yu Feibai showed a smug smile, did not hesitate to spread his legs, stood on the two planks on the left and right, and then stepped on both feet at the same time.

"Whew!"

In an instant, a large plank of wood shrank into the wall on the ground, revealing a wide doorway and a staircase leading to the ground. The dark and dim environment made Wang Guan and the others surprise for a while, their heartbeat increased slightly, and there was an inexplicable sense of excitement...... (To be continued......)
