''Oh, dear Susan, I don't think I'm any different today than I have ever been, the only difference is that I don't have any money today.'' Ah Yin still didn't understand, and examined himself from head to toe and came to the above conclusion.

Susan laughed out loud, only thinking that Ah Yin was very cute, and smiled; ''Oh dear, your charm is simply unstoppable. ‘’

''Susan, is it because we gave the money to our own country?'' Ah Shui asked tentatively.

''yes, you're right, your own life is already very difficult, and it's amazing that you can do this, and I feel like I should give you a little reward.'' Susan said sincerely, giving them a thumbs up.

''Oh, yes, yes, reward, reward. Ah Yin suddenly realized, said with a smile, and stepped forward to gently hug Susan's waist.

''Oh, I've got a little more to do, have a good day, goodbye, Susan. Ah Shui hurriedly finished speaking, and left without looking back.

The reason why Ah Shui wants to leave is because he thought of a strange question, he donated money to his country, but a foreign girl wanted to reward himself in her way? Where does this really start? Only a heartless person like Ah Yin would accept it calmly.

Early the next morning, Qin Tianlong boarded a train bound for Princeton, New Jersey, a long journey that would take thousands of kilometers across the entire continental United States, from the Pacific Coast in the west to the Atlantic Coast in the east.

The journey was lonely, Qin Tianlong felt very difficult at the beginning, and hoped to end this boring journey as soon as possible, but when the train drove into New Jersey, Qin Tianlong suddenly became afraid, Liu Changfeng gave high expectations for this transaction, but Liu Changfeng also said that the success or failure of this transaction depends on the attention of the Americans, what if it does not attract the attention of the Americans?

Qin Tianlong felt more and more uneasy in his heart, and only hoped that the train would arrive at Preston slowly. In the final analysis, Qin Tianlong was afraid that the transaction would fail and disappoint Liu Changfeng.

With a long whistle, the train rumbled into Preston train station and came to a slow stop. Do your best to obey the fate of heaven, and if you do your best, you will have a clear conscience, as for the result, let it be fate, Qin Tianlong tried his best to decompress himself, took a deep breath, and suddenly felt much better, got up and took his luggage, and got out of the car with the flow of people.

Preston is located in the northeast of the United States, the climate is much colder than San Francisco, as soon as he got off the train, Qin Tianlong felt a chill on his face, it was snowy outside, white and expansive, it was snowing, the sky was gray, and the goose-featherlike snow was fluttering down, Qin Tianlong subconsciously tightened his shirt and looked up at the sky.

Due to the snow, the road conditions in Preston are not ideal, although the weather is bad, there are still many hard-working taxi drivers who are forced to make a living, their business is not good, Qin Tianlong was invited by an enthusiastic driver to get in the car and set off for Princeton University.

''Hell, this Fack's weather, still doesn't let people live?'' There are so many snowdrifts here that no one has cleaned up, are all the sanitation workers dead? Fake. Amid the nagging whining of the taxi driver, the taxi slowly pulled into Princeton University.

''Good luck.'' The taxi driver collected the fare, threw down a blessing, and drove away.

Familiar campus, familiar roads, familiar taste, returning to his alma mater, revisiting the old place, Qin Tianlong was excited. The school has not yet opened, and with the snow and few pedestrians on the road, it seems a bit deserted.

At dusk, because it was winter, the sky had begun to darken, Qin Tianlong thought for a while and decided to go straight to Feng and Neumann's house.

Neumann is one of the greatest scientists of the twentieth century, he has a wide range of knowledge, has achieved outstanding achievements in many fields, can be called a generalist, is deeply respected, and he is also a social person, in his home, often hold some academic research seminars, and will last for a long time, the participants in the seminars are extraordinary, either unique achievements in a certain field, or emerging young talents. Of course, their so-called academic seminars are informal, and they do not sit in a dull conference room for meetings, but in the form of a drinking party, listening to their favorite music, drinking their favorite wine, and casually exchanging and discussing, the atmosphere is warm and harmonious.

As a student of Neumann, Qin Tianlong naturally knew Neumann's interests and hobbies, and in such a bad weather situation, he was most likely calling friends and drinking red wine comfortably in the warm home. Sure enough, when Qin Tianlong came to the outside of Neumann's house, the lights were bright inside, and music could be heard through the window.

Qin Tianlong took a deep breath and slowly knocked on the door of Neumann's house, the door opened, and a white woman in her thirties appeared in Qin Tianlong's eyes, Qin Tianlong recognized her as Miss Ruth, Neumann's assistant.

''Hi Miss Ruth, how are you?'' Qin Tianlong greeted warmly.

''Oh God, I can't believe my eyes. Ruth covered her mouth with her hands in surprise and said in surprise.

''It's me, Qin Tianlong. Qin Tianlong said with a smile.

''Of course I know it's you, I just can't believe it, dear Qin, welcome.'' Ruth gave Qin Tianlong a hug.

''Miss Ruth, this is my gift, please accept it. Qin Tianlong handed two bottles of fine red wine to Ruth.

''Oh, thanks, please come in.'' Ruth took the gift and shouted aloud inside; ''Dear Neumann, guess who's coming?''

Qin Tianlong walked into the huge living room with his luggage and Ruth, the living room was as warm as spring, elegant music flowed in the room, more than a dozen people sat lazily in the soft sofa, holding a goblet in their hands, the wine in the cup was as red as blood, and the room was filled with a faint aroma of wine.

A middle-aged white man in his forties put the cup on the table next to him, stood up with a smile on his face, and gave Qin Tianlong a hug.

''Hi dear Qin, why are you here?'' The middle-aged white man said enthusiastically.

''Oh, Mr. Neumann, I have come to you. Qin Tianlong said straight to the point.

''Oh, really?'' It's great. Neumann laughed out loud at the rest of the room; ''Guys, let me introduce to you, this is my student, Qin Tianlong, he is from China, uh, by the way, Qian Xuesen, it seems that you are also Chinese, right? You are so close and close. ‘’

A young and handsome Asian walked over with a smile on his face and shook hands with Qin Tianlong, if Liu Changfeng was here, he would definitely be surprised, because he was known as the "father of Chinese missiles" and "the father of China's aerospace." The famous Dr. Qian Xuesen was called by the vice chief of the US Navy as a person who "is worth five divisions wherever he goes."

Of course, he is still a student at the Massachusetts Institute of Technology in California, and is the most proud student of the great scientists of the twentieth century, Feng and Carmen. Even Qin Tianlong didn't know Qian Xuesen's future achievements, but he also knew that being able to be invited by Neumann proved that he was good enough and very remarkable. (To be continued.) )
