I am cannon fodder, but I can hug thighs

"I see." Lin Jin nodded repeatedly, not quite understanding. This was similar to black holes, which were all within the scope of research of scientists. "Then I'm curious about one thing. Can you tell me?"

[Host, please tell me if I can answer this question. It depends on the host.] The system did not agree first. There are some questions that Lin Jin cannot answer.

"Can the calculation of pi be completed?" Lin Jin was really curious. After all, she knew that pi had been calculated to tens of trillions of digits and had never been completed. "You can calculate the future, and there may even be many functions that we can't imagine. Has pi been calculated?"

[This cannot be told to the host. ]

Lin Jin laughed meaningfully: "I understand, your secret is pi."

System: [Host does not need to know these things. Host will not study them anyway. Even if you really want to study them, I am afraid you will not be able to figure them out until you die.]

"I'm just curious. If you can't say it, then don't say it. You don't allow me to say a few words." Although the system cannot reveal anything, Lin Jin still vaguely understands the meaning of the words. She must have guessed correctly, "After you left, I couldn't find these topics to chat with others even if I wanted to."

You have to know that this is still an era dominated by the theory of a spherical square.

"Are you whispering to that system again?" Liu Zhengqing glanced at her sideways, "Don't you want it to leave?"

"That's not the case. The main thing is that as long as the system is there, everything is very convenient. Plus, I treat the system as a friend, so I would be reluctant to let it go." Lin Jin frankly admitted his thoughts, "Of course, the most important thing is that the system can really help me a lot."

[Host, sometimes what you say is really... warm and heart-wrenching.] The system feels fortunate that it does not have a human heart or anything like that.

"You don't have a heart." Lin Jin bluntly criticized the system, "So how can it hurt? What's more, what I said is true. This is also a recognition of your ability. It shows that you are really amazing."

System: [Haha. 】

Everything was just as the system said. Nothing happened until the next town. Everything went very smoothly. Lin Jin could only attribute everything to the fact that he was thinking too much and the collapse of the mountain road was just a coincidence.

Lin Jin hates going out on rainy days, especially since the roads here are all muddy and only some roads in the city are paved with tiles, so if you go out on rainy days, your clothes and shoes will get dirty easily, even when you ride a horse.

Although the groom at the post station would help wash the horse, the weather was still a bit cold and she was worried that Qiong Yu would get sick.

"It's good to stay indoors on rainy days." Lin Jin sat by the window, watching the drizzle. If she wasn't planning to return to the capital, she would definitely wait until the ground was completely dry before starting her journey.

[It rains a lot in the south, and it’s almost spring now. Oh, come to think of it, it’s indeed starting to rain now.] The system pulled up the weather forecast. According to Lin Jin and the others’ route back to Beijing, it will rain for the next few days. [It will be light rain for the next few days. There will be no more heavy rain like last night.]

"Now that you put it like that, I feel even more that something is wrong with yesterday's rain and the collapsed cliff on the official road." Lin Jin sighed deeply, "No, System, tell me again, there really won't be any accidents because of the official road, okay?"

The system was somewhat helpless: [No... But after you change your route, you may meet old friends. ]

Although the official road was only changed into a mountain road, the two people did not go to the town that had been previously decided, so a part of the journey later would also be changed.

"Old friend?" Lin Jin was a little surprised. She had met quite a few people in this era, but not many of them were friends. There were even fewer people here. How could she meet an old friend? "Are you on good terms with me?"

It should be just a simple acquaintance, otherwise she really couldn't imagine who she would meet.

[Not bad.] The system analyzed the relationship between the two people and they could barely be considered friends. [But it's hard to say, after all, the feelings between many of you will fade over time, but I can guarantee that we can still get along well even if we meet.]

Lin Jin raised his eyebrows slightly: "It will fade away with time."

That was an acquaintance we had long ago, at least a long time ago for the people in this world.

She suddenly thought of something: "Jing'an?"

If she returned to this place again, the circle of people she would know would be even smaller. The only old acquaintances in the south with whom she could be considered to have a decent relationship would be Princess Jing'an who was still studying.

[I cannot tell the host for now, and it is only possible to meet, not certain. 】

"Ah? It seems that I guessed wrong. If it was Jing'an, you would definitely tell me directly. After all, this is not a secret." Lin Jin didn't expect that she guessed wrong. The doubts in her heart deepened, "Who is it then? Who else do I know?"

Old friend, that must be a long time since they last met. Who else has she not seen for a long time? She has no impression of anyone else.

"System, can you tell me a little more? Is it really not Jing'an?" Lin Jin thought for a long time but couldn't think of any friends he hadn't met for such a long time since he came back.

The system hesitated: [It may not happen. ]

"But I want to know." Lin Jin was aroused by the system. "Were you just trying to trick me? It was Jing'an, right? You just knew that I would analyze your words, so you set a trap according to my thoughts."

The system was somewhat helpless with her: [It's not Jing'an. Jing'an should be almost in Beijing now. Even if the host gallops, it's impossible to meet Jing'an. It's another old friend. ]

Lin Jin: “…”

It was over, and even more annoying, she couldn't remember that she knew anyone else.

"Are you sure you are my friend?" Lin Jin wondered if the system had misidentified her interpersonal relationships.

【It’s an old friend.】 The system corrected her statement.

"Not necessarily a friend, that would be a very wide range." Lin Jin held her face, but even so, the one who made the system remind her should be able to make an impression on her, "Really... who is he?"

"Does the collapse of this mountain road really have nothing to do with you?"

[Host, we are a system, not criminals, and we will not do anything that affects social order.] In this era, the transmission of information depends entirely on manpower. If the collapse of the mountain road delays important information, they will also be held responsible.

Lin Jin laughed dryly, a little embarrassed: "My fault, my fault."

The system knew too much, and there was an accident on the way from Lingnan to Beijing last time, and it was also a rainy day, so it was normal for her to have some PTSD.

[Host, I will leave this plane in the last three days. If you need anything in the next few days, you'd better hurry up.] The system seemed to be afraid that Lin Jin would not squeeze out its value, reminding Lin Jin to seize the last time.

Lin Jin thought about it and realized that she still needed the system's help: "Then give me some saplings."

[Saplings? Host, are you going to give the saplings to the government?] The system quickly figured out Lin Jin's purpose. Because the landslide occurred due to heavy rain, there was indeed a problem with the geology, and it was normal to need to prevent wind and sand.

"That's right." Lin Jin snapped his fingers. "Then treat the rest of the time as a holiday for the system. There's nothing to do. The main thing is that I don't know what to do. If you're not in the capital, you'll have no place to use your skills. It's better to let you have a good rest so that you can remember me for a while longer after you leave."

She knew that she was probably just one of the many hosts brought by the system, nothing special, and the system would probably forget about her in no time.

[Host, have you ever heard of a saying? 】
