When Zhou Yu hurried back, he found that Chen Yu was still sitting in the room in a good manner. And she is now changing clothes, and halfway through the change, the two of them look at each other.

The wonderful scenery was in full view of Zhou Yu. Chen Yu, who saw it, suddenly blushed, and said coquettishly: "Brother Zhou... You... What are you looking at, don't look at it..."

"Uh... I'm sorry, I heard your scream just now, so I hurried back, what happened before?" Zhou Yu hurriedly explained.

But Chen Yu felt surprised, and she asked, "What are you talking about?" I didn't scream or make a sound just now. ”

"Didn't you make a sound?But I obviously heard your call just now, did I hear it wrong?" Zhou Yu looked dazed.

Chen Yu didn't answer, just looked at him blankly, and his overall gaze seemed to say that you didn't come in on purpose to see me change clothes, right?

Thinking of this, Zhou Yu didn't say a word and left quickly. Keep going back and do what he's supposed to do.

However, after such a fuss just now, Chen Yu didn't seem to be as scared as before.

The two of them slowly began to adapt to life here, although it was always terrifyingly quiet, but Zhou Yu would always make some noise, and the atmosphere of the two in a room gradually overshadowed the feeling of fear.

It's just that when it was almost midnight, something strange happened here.

There is always some sound similar to the collision of metal in this building.

"Knock~"

"Knock~"

At first, Zhou Yu and the others thought it was the bell of the table clock, but slowly they found that there was still a certain difference between the two.

Chen Yu couldn't fall asleep tossing and turning, and finally got up and shook Zhou Yu's arm, and asked, "Brother Zhou, listen quickly, where is this sound coming from?" I feel as if I am upstairs, and this is not like the sound of the grandfather clock, I listened carefully to the sound of the grandfather clock just now, but the other sound is like the sound of metal impacting?"

Zhou Yu listened carefully, as if he did tell Chen Yu.

I turned on the light and found a dilapidated and even rusty flashlight in a drawer in the room. He walked out of the room with his flashlight in hand, wanting to find out.

After all, if they don't figure this thing out, they probably won't be able to sleep that night.

Zhou Yu didn't dare to stay alone in the room, so he had to keep up with Zhou Yu's pace. She held Zhou Yu's hand all the way and never dared to let go.

When I went upstairs, I could feel as if there was wind coming down from upstairs. Whirring, a little bit weird too. It stands to reason that this building has not been inhabited for a long time, so it should be dusty and dirty.

But Zhou Yu carefully observed, and he found that there was no dust in this floor, and there were no cobwebs in the corners of the walls. It's clean, a little too quirky, as if someone is here every day to clean it.

But they had been here for most of the day, and there was no sign of anyone else.

They came to the third floor, which was not much different from the second floor, with the same many rooms and the same elaborate design.

The only thing that made them feel different was that the sound of metal hitting that they had heard before seemed to be getting closer and closer.

Zhou Yu confirmed: "Chen Yu, why didn't you hear it wrong! This voice is upstairs!"

After thinking about this information, they were a little happy and a little scared. I was happy because I had finally found the source of the sound, and I was scared because I didn't know how the sound came from.

When the two of them sneaked to the fourth floor, they finally found the clue.

The fire on the fourth floor was in the sky, and from time to time there was a sound of metal colliding, accompanied by the sparks. After a corner, Zhou Yu saw that there was a particularly short old man on the fourth floor, banging on the metal here.

Because it was so dark that they were far away, they could only see the old man's back.

Just as they were hesitating whether to go over and ask the old man, the old man took the initiative to find them.

"Since the two little dolls have already lived here, why don't they come over to say hello?"

The old man's voice sounded a little vicissitudes and a little casual.

Zhou Yu and Chen Yu glanced at each other, nodded separately, and then walked in the direction of the old man together.

After getting closer, Zhou Yu realized that the old man was creating some kind of object. There were a number of mechanical objects around him, but he didn't realize what they were.

But there was a black box on the table, which he recognized, as if it were a firearm.

Chen Yu came to those objects, looked at them carefully, and asked boldly: "Grandpa, may I ask what you are doing? By the way, do you live here? Sister Zhao told us that it has been a long time since I lived here..."

"Hehe... Yes, there are no people living here, they don't treat the old man as a human being, and now these juniors are becoming more and more unconscionable. When the old man said this, he sighed silently. It seems to be really sad.

Zhou Yu and Chen Yu didn't know how to answer, because they didn't know what was going on in the Zhao family.

Even Zhao Shuangzi can't be said to have a complete understanding.

The old man said: "Forget it, it's useless to tell you about these past things, since you are here, let's talk to the old man with me, this place, no one has been here for a long time." ”

"Hmm. ”

Zhou Yu and Chen Yu nodded.

"After decades, the Zhao family has long been unaware of what they are fundamental. Now those young juniors are testing their own business and working hard to make money, these things left by the old ancestors, only the old man, I am still holding on to it, and I don't know when the inheritance will be completely broken..."

The old man was referring to the iron tools he made around him. Zhou Yu took a general look, most of them were hidden weapons, and there were some firearms.

These things are so intricately designed that you will want to take a closer look at them. It was hard for Zhou Yu to imagine how this kind of thing could have been forgotten here for so long.

He picked up a few bows and crossbows and took a closer look, and found that the design of the mechanism was really small and exquisite. When he picked it up and made an aiming motion, he happened to be seen by the old man.

So the old man asked him, "How, young man, is he interested in this? If you want to learn, I can teach you!"

"Really, can I really learn?" Zhou Yu asked with some excitement.

Chen Yu also looked at the old man with the same expectant gaze.

"Of course, there aren't many people who are interested in this thing these days. As long as you are willing to learn, I am willing to teach!"

After speaking, the old man took out two old-looking drawings from the drawer and handed them to Zhou Yu and Chen Yu.

He said: "If you want to learn, first memorize the contents of the drawings for me, and I will teach you how to make them tomorrow." ”

"Okay, thank you, old man. ”

The drawings are complex, but they are clear. Although Zhou Yu didn't understand this aspect, he knew at a glance that this drawing was genuine.

After that, the old man didn't let them go first, he had to concentrate on making what he had in his hands.

After this incident, Zhou Yu and Chen Yu had long lost the feeling of fear in their hearts. Some are just full of curiosity and anticipation.

Curious how much they could learn from this drawing, and hope that tomorrow the old man will teach them what to make.

Originally, the two of them planned to start resting after looking at the drawings for a while, but they didn't expect to suddenly receive a call from Zhao Shuangzi in the middle of the night.

Although it was his number, the voice inside was a man's voice. This voice sounded powerful and powerful, and judging from the voice, the other party should be a middle-aged man.

The other end of the phone said: "You are Zhou Yu, right? Although I don't know where you are hiding temporarily, I warn you that it is best to come to the door of the Roche Group by yourself tomorrow morning, otherwise, I dare not guarantee what will happen to Zhao Shuangzi and her company!"
