At this moment, Wu Tongguang and Li Wutong are staying in front of Nanjing University, which has a long history and has always been responsible for social progress since its inception.

"How could this teacher who teaches engineering have anything to do with the 'Great Assassin' Zhuo Shaoqing." Li Wutong asked curiously.

Wu Tongguang said: "This can only be understood by finding him himself." ”

Wu Tongguang and Li Wutong came to the communication room, which was a small bungalow, and there was a big tree next to the house, and the two of them didn't pay attention to what kind of tree it was, the tree was very tall, and the shade of the tree covered half of the roof of the communication room.

There is a stone bench with footsteps outside the window of the communication room, which can accommodate a person to stand, and the person can stand up just enough to reach the window of the communication room.

Wu Tongguang stood up and knocked lightly on the window.

Inside the window, a person who happened to look like a security manager sighed, wiped the fog on the window with his sleeve, put on his glasses, and looked at Wu Tongguang and Li Wutong: "Do you have anything to do?" ”

Wu Tongguang said: "I am from the Garrison Command. Wu Tongguang knew that at that time, most of the Kuomintang Youth League and the party headquarters of the campus were in control of the school's security organs.

The guard didn't seem to hear clearly, and said, "Is there something wrong with you?" ”

"I'm looking for a professor surnamed Zhu who teaches engineering here."

The guard asked, "Who are you?" ”

Wu Tongguang wondered if this person's ears were a little bad, and he said again: "I am from the Garrison Command, and I came to visit my friend, his surname is Zhu, and he teaches engineering at this university. ”

"Oh, sir, according to the rules, can I take a look at your papers first?"

Wu Tongguang took out his certificate, a big badge on the certificate, this is the old man's head of the Military Command Bureau, although the certificate is a new certificate of the Secret Bureau, but just looking at the certificate number and Wu Tongguang's position, you know that the origin is not small, but after all, the Garrison Command and the Secret Bureau are not the same department, so Wu Tongguang took out the certificate at the same time, and used his thumb to cover some specific names seemingly unintentionally.

When the guard saw that it was a high-ranking cadre, he immediately became nervous: "Sir, wait a minute, I'll call immediately to confirm that Professor Zhu is not there?" He turned around and grabbed the phone, the phone had a somewhat Hokkien accent, and the distance was far away, and Wu Tongguang didn't hear a word clearly.

After a while, the guard walked back with a smile, looked at Wu Tongguang and Li Wutong, and smiled: "Professor Zhu is still in class, or you wait here for a while, or ......."

"Let's go around the school first."

"Okay, then I'll accompany the two chiefs, you can go to Professor Zhu's lounge and wait for him first." The guard looked uneasy about the two of them.

"I don't need this for me, you can get busy!" Li Wutong said.

The guard hurriedly said: "I don't have anything to do, besides, there are so many campuses, I'm afraid you don't know the way, besides, now the school is also unstable, there is a riot, if the chief sees that something happened to his friend in school, how can I bear it." ”

As he spoke, he kept nodding his head and bowing, his attitude was so sincere that Wu Tongguang and Li Wutong didn't look at him like they were fake. Li Wutong still wanted to refuse, but Wu Tongguang touched her arm: "This little brother is kind and leads us to Professor Zhu, which also saves a lot of time." ”

The one nodded uncontrollably.

So the three of them entered the campus.

The guards kept introducing the school. Li Wutong looked at Wu Tongguang, Wu Tongguang of course knew what she was thinking, so he said: "I didn't come here before, and I was on a business trip, so I didn't pay attention to the scenery in the school. ”

While talking, the three of them passed by the teaching building, a corner of the building was full of creepers, and the sound of the gentleman's lecture and the sound of the students discussing came from time to time in the building.

Wu Tongguang immediately asked Li Wutong: "Do you know that in the late Qing Dynasty, there was an official named Sheng Xuanhuai who came here. ”

"I haven't heard of it, anyway, there shouldn't be a few good officials in the late Qing Dynasty, otherwise the people wouldn't be so miserable......"

Wu Tongguang didn't explain much, but said: "This person is both a businessman and an official, and finally, under the instruction of the Qing court, announced the 'state-owned railway', which triggered the 'Road Protection Movement' and ignited the fire of the Xinhai Revolution." There is a saying that 'the prosperity of the public and the prosperity of foreign affairs, and the history of its own theory', but his contribution to education is indelible, so some people in history later regarded him as the father of China's higher education.

In 1881, Sheng Xuanhuai was appointed as the general office of the Tianjin-Shanghai telegraph land line, and the following year he was entrusted by Li Hongzhang to establish a telegraph line from Shanghai to Guangdong, Ningbo, Fuzhou, Xiamen and other places.

When mentioning the telegram grandfather, Wu Tongguang's brain suddenly flashed the simple score of "Guiyan", and the notes in those simple scores should not only be notes, but numbers, such as "do", which should correspond to the number 1,"

e" corresponds to the number 2...... So what Wu Tongguang doesn't understand is that if the number represents the code.

Even if the note numbers represent the code, what do the rests, high notes, lines, and so on in these scores represent?

One question after another appeared in Wu Tongguang's brain, and it seemed that all the speculation could only wait for the mystery to be solved, but how to solve the mystery?

He sorted out the whole reasoning process: the two of them searched for clues and finally found the simple score, since Lei Yin chose this piece as the riddle, its riddle must be from the Chinese characters corresponding to these numbers, see through the surface, and thus return to the truth.

First, the invisible ink on the half-cut book hid the verses, and through the verses, he found a collection of transcribed poems with the same handwriting, but the "Returning to Yan" recorded in the poetry collection was a song, so he and Li Wutong found the score of "Returning to Yan".

So, what should we do next, starting from this score?

Wu Tongguang, who was deep in thought, was suddenly interrupted by the guard.

The guard said: "The chief is very knowledgeable, and he knows so well about the old things at the end of the Qing court. ”

Li Wutong smiled: "He's just a nerd." ”

While the three of them were talking, they heard the bell ringing for the end of class.

Wu Tongguang asked, "How long is the break between each class?" ”

The guard said: "More than 15 minutes, less than 10 minutes, alternate with each other, look at this time, it should be a 15-minute break."

The three of them walked up the stairs and quickly walked to Professor Zhu's lounge, the door was closed, there was no movement inside, they waited outside for a while, and the 15-minute break was almost over.

Wu Tongguang felt a sense of foreboding in his heart. At this moment, Wu Tongguang and Li Wutong are staying in front of Nanjing University, which has a long history and has always been responsible for social progress since its inception.

"How could this teacher who teaches engineering have anything to do with the 'Great Assassin' Zhuo Shaoqing." Li Wutong asked curiously.
