I held my breath and walked slowly along the iron plate next to me. Qinghan and Xiao Yusheng hurriedly protected both sides of me. When I walked over, I saw that there were quite a lot of iron plates, and they could be roughly judged by their shape. These things could be closely attached to each other to form a huge iron plate.

The white fine sand used to extinguish fires is stored in a secret room made of these things.

However, now that the building has collapsed, these mechanical claddings have been destroyed. We have no way to figure out how they fit together and how they operate. However, it can be imagined that a small keyhole switch can control such a large mechanical cladding, which shows how tight and exquisite the mechanical cladding is.

I reached out and gently stroked an iron plate.

The sun was hot and there was a hot temperature on it, but I couldn't let go for a long time, as if I couldn't let it go in my heart. I really didn't know how much thought my mother was hiding under these seemingly ordinary things, just like this secret room that I couldn't see.

Qinghan also gently stroked the heavy iron plates, thinking about something.

It took Xiao Yusheng to say, "Miss, senior brother, I'd better go back. This place has collapsed, maybe there is any danger. When it's late, I will let those senior brothers come to clean up."

I nodded silently, and they helped me slowly leave the ruins. Xiao Yusheng went down to arrange for someone to go, and Qinghan accompanied me back. When they walked to the corridor, both of them stopped involuntarily.

The scenery of this place should be the best in the west, transparent from north to south, you can see mountains surrounded by green trees, and the rivers in the distance meandering, like a ribbon shining with silver light wrapped around this landscape painting, which is particularly lively.

The mountain wind blew, bringing coolness, and I watched the clouds and mist surging on the top of the mountain, as difficult as my mother's thoughts, and my own thoughts drifted away.

At this time, Qinghan said, "Did you find out?"

"…?" I turned to look at him in surprise: "What?"

"I looked at those iron tools just now and all I used were green mines."

"Qingmine?"

I thought about it for a while before, I remembered: "Is it the kind of ore that Pei Yuanxiu and the others wanted to buy through Slang Jiangcuo before?"

"That's right."

“…”

I was a little blurred for a moment.

We don’t know what to do for this ore, but Pei Yuanxiu attaches great importance to it. At such a critical moment, he did not forget to ask Xie Feng to go to Silang Jiangcuo to buy it. It should be of great use. Decades ago, my mother had already started using this ore and forged iron tools to build such a huge mechanism to protect the library.

Used to protect the library?

My brows slightly tucked—

Although I also agree with my mother and Fu Badai's practice of saving ancient books and maintaining culture, I still think that it is a bit overused?

Moreover, since Pei Yuanxiu attaches so much importance to green ore, this kind of iron ore should be of great use.

I told Qinghan what I just thought. He was silent for a while, and nodded gently and said, "Actually, I have been thinking about this question. Qingying, is this mechanical cursor designed by the Tang family?"

I thought about it and shook my head and said, "It's not like it. Although the Tang family is also a master of mechas, their mechas are mainly precise and compact, which is not very similar to this one."

"Then do you think, which one is stronger, the two types of mechanical sacred in the library, and the mecha bird that the Tang family gave you before?"

"It's actually hard to say something strong. The Tang family's mecha bird is so small, and some of the parts used are thinner than the needle tip. If you want to say it's precise, the precision of their mecha is difficult to meet."

"Um."

"But this mechanism in the library is so huge that it even involves such a large pavilion, and we have also seen those iron plates. It is probably more difficult to build such a huge and heavy mechanism that can make it run than to fly the mecha bird."

He nodded and said, "That's what I mean."

“…”

"This mechanism is definitely not simple."

“…”

"If it is just to protect the ancient books on this floor, it doesn't make sense, because there are still many labor-saving ways; and it takes too much manpower and material resources to design and build this machine, these two things are unequal."

I couldn't help but look back: "But my mother did this. What I had in that secret room was white sand that could extinguish the flames, and it was also this mechanism that saved our lives."

In fact, in addition to doubts, I should be more relieved. I had always been worried about whether the construction of a secret room was an impure purpose, but now, I know that my mother had anticipated a possible threat. She did all this to protect the ancient books in the library. She was still the gentle and peaceful person I remembered.

This is enough.

“…”

Qinghan was silent for a long time and said softly: "Maybe, I was worried too much."

|

Qinghan and I returned to our residence. Although it seemed that the dust had settled and many things had been resolved, we both did not feel relaxed, but were extremely silent. We sat in our chairs for the rest of the time. I didn't know what he was thinking, but I felt that my thoughts were very confused and needed to be sorted out.

As dusk fell, the earth, which had been sunburned for a whole day, was hot at this time, and the room was as hot as a steamer. Susu urged us to go out for a walk and get cooler, and she was going to prepare meals for us.

However, as soon as we left the door, we saw Lu Sheng coming.

He respectfully bowed to us: "Miss, Uncle Liu."

We nodded to him, and just as we were about to ask him what he was going to do, Lu Sheng saw Su Su preparing to walk to the kitchen, and said, "You two don't have to prepare supper."

"Um?"

"Just just now, the teacher told him to hold a banquet at the top of the mountain to invite the eldest lady and Mr. Liu to the top of the mountain."

"oh?"

We looked at each other unexpectedly, and a surprising light shone in our eyes.

Nan Zhenyi invited us two to a banquet?

Lu Sheng smiled and said, "The teacher knew that the two were particular, so he specially asked the chef at the foot of the mountain to deliver good wine and food. He just waited for the moon to rise to the willows, so he asked them to go."

Qinghan immediately said, "Okay, we will definitely go on time."

Lu Sheng bowed to us again, then turned around and left.

When he left, I turned around and told Susu not to prepare meals for me and Qinghan, but to ask her to prepare some medicinal food for Wei Yang, and then the two of them slowly walked towards the corridor.

The wind is the most comfortable at this time. The breeze blows with a cool breeze, taking away all the heat.

After a quiet moment, I finally spoke first: "Why do you think Nan Zhenyi is treating us to the banquet?"

Qinghan thought for a while and said, "Although he is very thoughtful, he is actually very straightforward and simple in doing things. He can do whatever he should do; he can't even look at what he shouldn't care about. Since he is asking us two to go to the banquet, in addition to really having to enjoy some delicious food, I think there should be some things that should be explained to us, and he wants to explain them."

"oh……"

I was silent for a while, thinking about what he wanted to explain to us, but after thinking for a while, I felt that I was asking for trouble. Since Qinghan had already said that Nan Zhenyi was very simple and direct in doing things, then only he could choose what to do. No matter how we think about it, it would be useless.

So, I shook my head with a smile, Qinghan turned his head to look at me, and asked, "Why are you laughing at?"

The cool breeze blew, and when he turned his head, a strand of hair was blown on his face. I reached out to brush it away, and then smiled and said, "I was wondering what would Nan Zhenyi eat when treating him?"

He was stunned and laughed immediately.

"I can't eat some carrots, do you?"

"What do you think? Do you think of him as a rabbit? To be honest, he is very particular about food, clothing and food."

"Oh? It's very expensive?"

"It's not about spending money, but he is the kind of person who can live more comfortably than others without much money."

"oh?"

"So, I'm looking forward to this evening's dinner."

"It's great. I'm hungry, so I'll go up and have a big meal for him later."

"You are like taking advantage of others like this."

We were joking for a while, but soon it became dark. The moon slowly climbed up from the north of the west mountain. Lu Sheng and Xiang Wenliang came over with lanterns to take us up the mountain.

Unlike that night, because there was no tall library pavilion behind us. When we climbed the stone steps again, our vision became much wider. Moreover, when we reached the top of the mountain and passed the gate, we saw that the closed door that night had been wide open.

Lu Sheng said, "The teacher is waiting inside, please ask you two to come in."

After saying that, they saluted and turned around and left.

The lantern was also taken away by them, but it was not dark in front of us. Because there was a light inside the door, there was also some light outside. We walked slowly into the light shining from the door and walked into the door.

The first thing I saw was a small pond, and behind the pond was a whole piece of strangely shaped rockery.

The shape of the stone just matches the shape of the pond. You can tell at a glance that the entire stone is dug out and then formed a pond. This artificial scenery is still natural and interesting, which is refreshing.

Bypassing the pond and rockery, behind it is a large open pavilion, and the corridors on both sides extend to places that cannot be seen in the night.

In the open pavilion, the lights illuminate a couplet hanging on both sides of the door—

Thoughts follow thousands of years, and condense the past and present in a moment.
