  When Lin Hong and his party arrived at the Youyi Hotel, Cook had been waiting there for some time.

  When he saw Lin Hong take out the enlarged circuit diagram again, he had even more confidence in Lin Hong's product. He strongly suggested that Lin Hong integrate the signal amplification function into the original diagram.

  Integration is not difficult, Lin Hong almost completed the overall design of the drawings on the spot.

  There was nothing more for him to do, and Mu Si Min took over the work and began a detailed discussion with Cook.

  According to Musim's opinion, not only the patent for this product needs to be applied for, but also the design method and the most basic circuit diagram should be applied for at the same time. In this way, even if others want to imitate similar products later, they cannot use similar circuit principles and can only think of other ways.

  Cook was also very much in favor of this. They soon reached a series of consensus and drafted the relevant entrustment agreement. Since Lin Hong is still relatively young now, he does not have corresponding identification, so his guardian Feng Wen signed on his behalf.

  After settling these, Cook was eager to see the final effect of the finished product, so he suggested going to an amateur radio club in Beijing, and let Lin Hong demonstrate it on the spot.

  Mosi Min also served as a temporary driver, and everyone rushed towards Beijing.

  Xu Wenjing was delayed a bit this morning, so when she rushed to the Youyi Hotel, she found that Cook was no longer in his room.

  Inquiring carefully at the hotel front desk, the other party is also not very sure about Cook's itinerary, only saying that they heard them mention the term "Jingcheng S Middle".

  Xu Wenjing didn't hesitate and quickly ran to the hotel parking lot, saying to the driver: "Quickly, go to S."

  "Ding ding ding——"

  Feng Anguo had just returned to his own office when the phone on his desk rang non-stop.

  "Hello, who is it?"

  "Second brother, it's me."

  Feng Anguo was taken aback: "Big brother? How did you think of calling me?"

  He felt very strange, as his elder brother Feng Anbang rarely called him at the office.

  A low voice came from the other end of the phone: "I'm asking, did Xiaowen go on a trip to Lingnan Province?"

  Feng Anguo paused for a moment before finally saying: "Yes. She went to Lingnan Province a few days ago to attend a meeting."

  "Some people say that when she came back, she brought a child with her, did you know about this?"

  "Who said that?"

  "Never mind this, I just want to confirm whether it's true or not."

  Feng Anguo sighed, "Yes. Big brother, it's been so many years since this thing happened, are we still going to be stubborn about it? Xiaowen is already so old now, are we still going to continue delaying her?"

  "I know." The other party was unmoved by his questioning, "Come back for a visit over the weekend."

  After finishing speaking, the other party hung up the phone.

  Feng Anguo listened to the busy tone in the receiver and let out a sigh before hanging up the phone with a "click".

  Xu Wenjing hastily arrived in Beijing and rushed straight to the amateur radio club after getting off the train.

  While on the bus, she had already thought it through - they were only going to S for one reason: to test out Lin Hong's thing.

  But when she ran to the entrance of the club, she saw that Chen Xiaoyu, a member of the club, was closing the door and hanging up the lock.

  "Chen... Chen Xiaoyu, what about them?" Xu Wenjing was already exhausted and panting, she supported her belly and took big breaths of air as she asked.

  "Them?" Chen Xiao Yu was slightly stunned, then reacted, "Oh, you're referring to Mr. Cook and them? They came late, they left a while ago."

  "Quiet, you know, just now they brought a small box, directly connected between the radio and antenna, it can actually filter out most of the noise, no need to adjust the frequency at all, and it's clear as day. And then, after connecting another small tool, the original signal of 36, actually became 59, it's simply too amazing..." Chen Xiaoyu said excitedly.

  This is simply a divine instrument for amateur radio enthusiasts. With those two small devices, the wireless transmission and reception efficiency will be greatly improved, and the threshold for amateur radio will also be significantly lowered, making it easy for even beginners to operate the radio station.

  Xu Wenjing didn't have the heart to listen to what he was saying at this time, and she felt a deep sense of loss in her heart.

  She rushed all the way here, but still arrived a step too late.

  "Do you know where they went?" Xu Wenjing asked relentlessly, "Did they go back or are they still in school?"

  "This... I'm not sure." Chen Xiao Yu said helplessly, "But with a group of school leaders accompanying him, he shouldn't have left yet."

  Upon hearing his words, Xu Wenjing immediately ran back in the direction of the school office again.

  The administrative building is located on the north side of the campus, where the buildings are Western-style and were built by foreigners when the school was founded. The design is very good. After the expansion of the school, those buildings became the place for handling official business.

  There is a garden between the amateur radio club and the political and religious departments, called Bichun Garden, with a pool in the center.

  Xu Wenjing hurriedly and quickly ran through Bichun Garden, heading towards the direction of the Imperial School.

  But just as she left Bichun Garden, Lin Hong walked in from the other side.

  He came to the central pool and listlessly watched the few remaining red carp, occasionally throwing a small stone into it.

  Cook had just confirmed the function of his "adaptive signal filter", and Lin Hong immediately combined the circuit of the signal amplifier with the previous circuit, designed a drawing that integrated the functions of signal filtering and amplification, and handed it over to Cook to apply for a US patent.

  After finishing this matter, under the enthusiastic invitation of the school leaders, his mother Feng Wen and Mu Si Min held a symposium in the Political Education Department conference room.

  Also attending the meeting were some parents and students. The main content of the meeting was to allow those exchange students from the United States to freely choose Chinese families, after which they would live with their chosen families for a whole year.

  Lin Hong didn't like crowded places, so he found an excuse to leave the meeting and came here. He had seen that Bichun Garden was relatively quiet earlier, so he walked all the way here.

  Watching the carp swimming back and forth in the water, Lin Hong felt a little lonely. He missed his hometown.

  Dad's wood factory business, I don't know how it is. If the business is not good, he can't earn money, but if the business is good, he will be too busy to come home and has to work overtime every day. When I'm not at home, he should be too lazy to cook for himself?

  When will Dad come over?

  I don't know how Ah Huang is doing, I'm not at home, it must be hungry often, right?

  Alas, I should have known better than to keep it at home. Fortunately, it has learned to forage for food outside since it was young.

  ……

  Lin Hong had never been far away from home since he was a child, but this time he ran to thousands of miles away, and he couldn't help feeling homesick. He didn't have much feelings for this home in the capital city because the time was too short.

  Yeah, next time I'll give Sun Wu a call and ask him to come over here to play games, he's definitely going to like it.

  Just then, a clear and crisp voice suddenly came into his ear:

  “xzz！”
