The current package is not like that of later generations, there are too many packages and there may be loss, especially like the package sent to the Academy of Sciences, research institutes, aerospace institutes, etc., as long as the address is written on it, it must be careful and careful, and there must be no loss, because no one knows whether there is anything very important in it.

Of course, it is really very important, for example, when it comes to R&D secrets, it is impossible to send it through parcels, which is too child's play.

Under normal circumstances, important documents that are not classified can be mailed by parcel, and the parcel will not be handed over to Le Lao until the fourth day.

Le Lao didn't know that someone had sent him a package, and the students around him hadn't reminded him that there would be a package recently, and when he got the package, Le Lao also asked the students around him, "Someone recently told you that there was a package sent to me?" ”

Generally, when a package is sent to the Academy, the students of Le Lao will be contacted in advance to track whether the package is received on time.

Packages such as the Academy of Sciences will arrive on time, except for the kind that needs to be forwarded to a secret base, which will take a little time.

The students were not notified, and when they heard this, they shook their heads.

Le Lao was actually worried that the students forgot to tell themselves that someone sent the package, and when he saw this, he knew that the person who sent the package did not contact him first, but sent it directly.

Into the eye is a row of delicate but very stylish bones, the turning of the pen between the sharp pen words, very good-looking, at first sight you know that the person who writes has worked the practice of words.

Le Lao tore off the list on it and handed it to his students with a smile, "Come on, come on, you take a good look at this word, you guys, you have good professional knowledge, but some students are a little bit worse." ”

"Although now you write reports directly to the computer to print, but at any time you have to record your own notes, the recorded transcripts are very likely to be precious research materials in the future, if you can't even write well, scribbled and difficult to read, let the people behind you study your notes?"

"Look at this handwriting, it can be called a template, give you the next task, and hand me seven pages of pen and ink every week in the future, and I want to see who has made greater progress in half a year."

Le Lao talked with a smile while opening the package, and walked out of the laboratory, Le Lao was an approachable old man, who could talk and laugh with the students.

Le Lao, who has a good mentality, often jokes with his students, saying that his physical body is rare in ancient times, but his interesting soul has just come of age and is very energetic.

The students took the tore off postal slip and looked at the words on it, which really made them ashamed of themselves, every word was beautiful and easy to recognize, much better than their chicken feet.

Le Lao opened the package completely, and a thick notebook came into view, with a note pinned to the note, which read "Le Lao personally opened", and the note was signed "Student Shi Ning" under the note.

Shi Ning, the little girl she met on the train last time, has an active mind, is broad-minded, has an extraordinary conversation, and has very keen opinions.

The topics she talked about are still fresh in my memory: "In the 21 st century, when it is inevitable to belong to electronic information warfare, radar, communications, electronic warfare, and radio navigation will become informationized battlefields, and electronic reconnaissance, electronic jamming, electronic deception, electronic concealment, and electronic destruction will become ...... The battlefield is invisible, the more tangible is invisible, there are no chariots to hire, soldiers are charging, only thousands of electromagnetic waves in different directions and different frequencies are fighting for life and death in the invisible invisible space......"
