Regarding the matter of speeding up the train, she thought about it as early as the moment she took the train, it was too slow, and the improvement she provided, not to mention that it could be increased by seventy or eighty percent, but forty or fifty percent was still there, that is to say, if they succeeded in researching, it would only take about half of the original distance from the five counties to the capital in the future, which greatly shortened the waste of time on the train.

After Liu Qianqian returned to the dormitory, she sorted and packed all the things she bought today, and wrote on the outermost that the package was a gift to whom, so that when she arrived in the five counties, she could send the gifts directly without having to classify them one by one.

After tidying up for nearly an hour, Liu Qianqian looked at her watch, it was time to have dinner, Liu Qianqian put things aside, and then prepared to eat.

After eating, Liu Qianqian is ready to walk around the campus of Beijing University, the campus is very quiet, the temperature is just right at this time, neither hot nor cold, the students on the campus are full of vitality, some are in groups, some are alone, and there are couples strolling around the campus, in general, it is a very warm night.

Bang!

Liu Qianqian was hit by someone while walking, she raised her eyes and looked, yo, why is this person still so ghostly, isn't this the woman she met in the mall in the morning?

The girl bumped into someone, she didn't seem to care much, she didn't even say sorry, she ran straight forward in a hurry, as if she was chasing someone, Liu Qianqian sneered, and she didn't want to worry about a fool, after all, such a beautiful night, if it was destroyed by the brain, wouldn't it be a pity.

Zhao Jingshu didn't know that the person she had just bumped into was Liu Qianqian, and her whole mind was on Zhou Shuo on the basketball court.

"Brother Zhou Shuo, come on!"

Hearing Zhao Jingshu's voice, Zhou Shuo's eyebrows furrowed, but in front of outsiders, he still had to maintain his image as gentle as jade, so he nodded at Zhao Jingshu, Zhao Jingshu was dizzy, and Liu Qianqian, who was clearly watching next to him, sneered, it was really two neurotics.

After the campus trip to Jingcheng University, Liu Qianqian felt that Jingcheng University was indeed a good university, but it seemed that there were some problems with her vision, but these were none of her business, she just did her best!

Because she was going to visit her father's comrade-in-arms Yang Chunhe the next day, Liu Qianqian returned to the dormitory early, cleaned up and prepared to go to bed, and set off tomorrow full of energy.

The next morning, Liu Qianqian got up early, prepared the meeting gifts, went to the canteen for breakfast, and then prepared to leave with the gifts!

Because she knew Yang Chunhe's address, Liu Qianqian had already prepared a map of Beijing before departure, took a slow bus, and arrived at her destination an hour later!

Liu Qianqian looked at the address, and then looked at the soldiers standing guard at the door, and Liu Qianqian strode forward.

"Comrade, I want to find Yang Chunhe, I am the daughter of his comrade-in-arms, and I came to visit Uncle Yang!"

"Comrade, wait a minute!"

Liu Qianqian nodded and stood straight outside.

After a while, Liu Qianqian saw a neatly dressed woman hurrying over, and immediately laughed when she saw Liu Qianqian.

"Qian Qian, I'm your Uncle Yang's wife, Chu Ran, just call me Aunt Chu!"

"Aunt Chu, hello, I'm Liu Qianqian!"

"Come in, come in!"

Chu Ran pulled Liu Qianqian over, and then said to the soldiers standing guard on both sides, "This is the daughter of Lao Yang's comrade-in-arms, called Qianqian, you can just come over and let it in directly in the future!"

"Yes!"

Liu Qianqian nodded and thanked the two soldiers, and then followed Aunt Chu side by side.

Seeing the things in Liu Qianqian's hand, Chu Ran sneered, "Why are you so polite, why are you so polite, you just came, what kind of gifts did you bring, you were young in the capital, we should have taken care of you!"

"Aunt Chu's words are not right, my first visit, if I don't bring some greeting gifts, wouldn't I not know how to be polite!"

"Okay, you're right!"

Chu Ran has always wanted a daughter, but unfortunately after giving birth to Chu Xi, she didn't move, no matter how greedy she was, she couldn't stuff her son back into her belly, and she liked it when she saw Liu Qianqian, this little girl looked like a sign, her eyes were clear, and she was a good child at first glance.

"Your Uncle Yang is waiting for you at home, even your brother Chuxi said that he wanted to see you, so he specially asked for leave from school!"

The corners of Liu Qianqian's mouth hooked slightly, and she was quite happy in her heart.

Liu Qianqian followed Chu Ran's side, and many people in the compound saw it, and they asked curiously, "Sister-in-law, who is this little girl, who looks strange, isn't it the little daughter-in-law you are looking for for your Chu Xi?"

"I want Sissi to be my daughter-in-law, but it's a pity that that kid in my family is not worthy of such a good daughter as Sissi!"

From Lao Yang, she knew a little bit that this little girl was not simple, and she fell in love with this little girl at first sight, and her son was really almost.

"Yo, sister-in-law, what you said, Chu Xi is a top student of Beijing University, he looks like a talent, and his family background is also a good one, why is he not worthy of this little girl!"

"Hey, don't talk nonsense, this little girl is the daughter of Lao Yang's comrade-in-arms, she came to the capital to participate in the competition, some time ago, she also represented the country to participate in the M Olympiad competition, won the championship, the world's first, do you think my stupid big son can be worthy?"

"Yo, that's amazing, the little girl is really good!"

"Haha, that's, I won't tell you, Lao Yang is waiting in the house!"

"Go, go!"

Liu Qianqian obediently followed Chu Ran's side, did not talk, did not interject, and looked very well-behaved.

"Old Yang, Sissi is here!"

Yang Chunhe had already heard the movement in the courtyard, and hurriedly put down the newspaper in his hand, his face bloomed with a smile, and Yang Chuxi next to him rubbed the goosebumps on his hands, he seriously suspected that he had picked it up, otherwise why would his father laugh like that when he saw Qianqian, it was weird and terrifying!

"Uncle Yang is good, Brother Chu Xi is good!"

As soon as Liu Qianqian entered the house, she greeted Yang Chunhe and Yang Chuxi, Chu Ran had already taken out a pair of clean slippers for Liu Qianqian to change into, and it could be seen that this pair of slippers should have just been bought, thinking of this, Liu Qianqian's heart moved, and she was a little closer to Yang Chunhe and Chu Ran, and she naturally knew that she would repay Li with a peach, not to mention that Yang Chunhe and her father were comrades-in-arms and friends.

"Qianqian is here, hurry up and sit down!" Yang Chunhe greeted Yang Chuxi while driving Yang Chuxi to the other end of the sofa, Yang Chuxi expressed his grievances, Liu Qianqian was happy when she saw this, but she didn't expect Yang Chuxi to have such a side in private.

"Sissi, I've heard about it, I heard that our Huaguo won the championship in the Mathematics Olympiad this time, you are a great contributor, and you have earned back a great face for our Chinese people, see how the international community will say about our country's shortcomings in the future, Sissi, well done, hahaha!"

"This is what I should do!"

Liu Qianqian nodded, the moment she stood on the podium, the moment the national anthem sounded, and the moment the national flag was raised, Liu Qianqian was extremely proud in her heart, and at the same time, she was completely integrated with this era.

Whether it is in her previous life or in this life, what she has to do is to change domestic science and technology and world science and technology within her limited ability, in addition to the surging patriotic heart, another reason is to want to live a more leisurely life and a better quality.

"Good job!" Yang Chunhe seemed to appreciate Liu Qianqian's statement, he continued, "The growth agent you came up with in August last year has been studied by the researchers, and many other derivative potions have been thought of from it, which have a great effect on crops, you are a well-deserved hero, solving the problem of food and clothing in various regions, and even being able to make grain grow again and again!"

"But so far, the growth agent is still very important, after all, the food cycle is too short, and it will also have a certain impact on people's livelihood, so it is decided that the concentration of the growth agent will be deployed, which can not only increase the production of food, but also improve the enthusiasm of the people, and will not make the people below inert, Sissi, you invented this growth agent well, so how many people have enough to eat!"
