Started as a thatched house and ended up as a female figure

"Master, Jin Jin is about to tell you that Jin Jin has been upgraded."

After Jin Jin said this, he suddenly added in a low voice: "It should, it should be upgraded..."

Cheng Wan put down the pen in his hand, leaned back on the chair, clasped his hands on his waist, and said, "Tell me about the changes in this upgrade."

"The good change is that Jinjin has two more functions, that is, it is owner-centered. Jinjin can conduct real-time detection and monitoring within a radius of 100 meters."

Cheng Wan raised an eyebrow, "What about the bad changes?"

Jin Jin was silent for two breaths, and his voice was a little low, "Master, Jin Jin will only have five express delivery slots in the future, and he can randomly copy an express delivery every five days."

Cheng Wan blinked and thought to himself: "This is actually more like using Jinjin's ten express delivery slots and the ability to copy express delivery every day in exchange for the detection and monitoring functions within a hundred meters radius, and it is a 'forced' exchange. "

"Master, I'm sorry..."

Cheng Wan came to her senses and immediately understood what Jin Jin was thinking.

"Jinjin, I really like those two functions you have! They are also very useful to me!

Think about it, did you just tell me that you have detected stones that can replace some of the raw materials of cement?

How important is this? If it weren't for you, how would I know this? In the end, the busy work may be in vain.

And the monitoring function is even more powerful. With Jinjin, my safety will be more guaranteed in the future.

As for the fact that there are only five express slots left and you can only copy an express every five days, this doesn’t have much negative impact on me now.

Jin Jin, you have upgraded, and you have upgraded to a more powerful direction. "

Jin Jin was revived by Cheng Wan's words.

Although Jin Jin didn't speak, Cheng Wan could inexplicably feel that Jin Jin was in high spirits.

Cheng Wan's eyes flashed, and she asked casually, "Jin Jin, how did you become my golden finger in the first place?"

Cheng Wan had never delved into this issue before. She had always felt that Jin Jin was the matching golden finger for her "time travel".

But now she begins to wonder who created Jin Jin? Jinjin...is it really a courier locker?

"It's compensation."

Cheng Wan was stunned, "Is there some unknown reason why my soul went to another world and I stayed stupid in this world for more than ten years?"

Cheng Wan could only think of this, otherwise what else could he deserve to be compensated for such a golden finger?

Cheng Wan thought again that before she returned to this world, the eminent monk had predicted that she would come back when the time was up, and she couldn't help but get goosebumps all over her body.

At this time, Cheng Wan only felt that her world view was crumbling, and her body and brain had a crazy feeling of being separated from each other.

"Jin Jin doesn't know. Jin Jin only knows that Jin Jin is compensation for his master and will always accompany him."

Cheng Wan pinched her thigh hard in a daze. The next moment, Cheng Wan let out a cry of pain, and quickly rubbed the place where she pinched with a grimace.

The attack was ruthless.

"Jinjin, I am real, right? This world is real, right? My memories, the things I have experienced, the people I know... are all real, right? ?”

"of course it's true.

Master, even in modern times, aren’t there many things that science cannot explain?

What you are experiencing happens to be in a realm that science cannot explain.

You cannot doubt the authenticity of these things just because they cannot be explained scientifically.

It's unscientific. You traveled to modern times, lived for twenty-one years, and then returned to ancient times. This is the most unscientific thing, but didn't you accept it very well? And live a colorful life.

Master, the world is full of mysteries. Jin Jin feels that don’t think too much, living your own life is the most important thing. "

Cheng Wan stood up, opened the window, looked at the night outside, and listened to the movement outside.

"Xiaoyu, Sanping, you two, stop playing around. Come over here and wash your face, feet, and mouth, and then go to bed."

"Mom, when will eldest sister go to bed? Is the light in her room still on?"

"Mom doesn't know. It's time for your eldest sister to get ready for bed after she has thought about serious things. You will be less noisy when you enter the main room later. Don't disturb your eldest sister's thoughts..."

Cheng Wan chuckled lightly, his eyebrows arched, and his eyes shone with tiny light, "Yes, they are so real, how can I suspect that they are fake?"

Cheng Wan clasped her hands together, lowered her head slightly, closed her eyes, and her gentle and gentle voice was full of piety.

"Wan of the Cheng family is very happy to be accompanied by gold and gold. Thank you very much..."

Cheng Wan opened his eyes and kept his hands clasped together, "Jin Jin, do you think He can hear what I say?"

“Jinjin doesn’t know, Master, Jinjin doesn’t know who you are talking to?”

Cheng Wan: "..." OK.

In fact, she didn't know who she was talking to.

Just now she felt as if she knew something important, and she needed to make a statement.

Cheng Wan closed the window again, calmed down her mood and mind, then sat on the chair again and started asking Jin Jin about business.

"Jin Jin, where are the stones you detected that can replace some of the raw materials of cement?"

"In the courtyard outside your room."

Cheng Wan opened the door with an oil lamp and walked in the direction Jin Jin said in her mind.

Soon, Cheng Wan stopped in a corner of the yard.

"Master, the stone Jin Jin is talking about is the sky blue stone used for decoration around the roots of this tree."

Cheng Wan raised her eyebrows. She was no stranger to this kind of sky-blue stone.

This familiarity means that Cheng Wan previously thought that this kind of sky-blue stone was very beautiful and not very common, so almost every time Cheng Wan came to the backyard of the random building, he would come to this corner to take a look at this kind of stone.

One time, Cheng Wan tried to crush a piece of stone in order to study whether there were any other differences between this stone and other stones besides the difference in color.

In the end, nothing special was discovered.

From then on, Cheng Wan only regarded this stone as a decorative stone with a special color and did not bother to study it again.

Cheng Wan knelt down, holding an oil lamp in his left hand to illuminate it, and picked up a small piece of sky blue stone in his right hand.

"Jin Jin, are you sure that this stone can replace part of the raw materials of cement and use it to make cement that can pave roads in this dynasty?"

Outside, Cheng Wan and Jin Jin were communicating in their heads.

"Jinjin is sure."

Cheng Wan had a strange look on her face. She stared at the sky blue stone in her right hand for a long time, then pursed her lower lip and said, "Jin Jin, if you use this color of stone as raw material, the color of the cement you will make..."

Cheng Wan thought that the roads paved with cement might all be sky blue by then, and fell silent.
