Later, when the Electronic Countermeasures Regiment lifted the electronic interference, Platoon Leader Chen also exposed his position because of the radio.
This led to all the other Red Army scouts being captured by Wolf Fang, except for Platoon Leader Chen and Zhuang Yan, who had gone to deliver a message and escaped the ordeal.
However, Platoon Leader Chen escaped capture only because of an onset of ankylosing spondylitis.
But if he could turn bird language into a means of transmitting information, then in the upcoming military exercise, he could avoid the situation from the original plot where they were surrounded and wiped out by Wolf Fang because of the radio.
"What's on your mind? Tell us, and we'll help you brainstorm some ideas," Happy Baby said curiously after finishing his test paper.
"I'm thinking about how to turn bird language into a way to transmit intelligence," Lin Mu said.
"Using bird language to transmit intelligence?" Zhuang Yan asked curiously.
"Yeah, it's an idea that just suddenly popped into my head recently," Lin Mu said.
"Then you'd have to know bird language first," Happy Baby said from the side.
"Chirp, chirp-chirp, tweet, cuckoo, warble." The various bird calls Lin Mu imitated left Happy Baby and Zhuang Yan stunned.
"If I hadn't seen it with my own eyes, I wouldn't have believed a person could make bird sounds, and so realistically too," Zhuang Yan marveled.
"Yeah, it's exactly like what I used to hear in the countryside when I was a kid," Happy Baby said.
Lin Mu only gave a slight smile at this, sighed, and continued.
"If a person tries to imitate bird language, setting aside whether it sounds realistic or not, the key issue is that the transmission distance is limited," Lin Mu paused before adding.
"Use a whistle! Whistles are loud and carry far," Happy Baby suggested.
"I know that, but a whistle can't imitate the sound of a bird," Lin Mu said helplessly.
It was like someone guarding a buried treasure and knowing where the mechanism was, but not knowing how to open it.
It was very frustrating.
"I know how to do that," Happy Baby said.
"You do?" Lin Mu and Zhuang Yan asked simultaneously.
"Yeah, when I was a kid, I often saw my grandfather put a whistle in his mouth and blow it. As soon as the whistle sounded, birds would definitely land near him."
"Later, I pestered my grandfather to teach me. He had no choice, so he first taught me how to make the whistles and then how to blow them. But because of my voice, I could never make a clear, high-pitched sound."
"So, over time I forgot about it. I didn't expect to hear it from you today; it instantly brought back my childhood memories," Happy Baby said, his voice slightly choked up as he looked at Lin Mu.
Lin Mu, who had never comforted anyone before, was even more at a loss in this situation. He scratched his head and simply took Happy Baby's chemistry test paper.
He used looking at the paper to escape the somewhat awkward scene.
"Lin Mu, I'll still make a few whistles for you. Consider it thanks for helping me tutor chemistry. To be honest, I've been thinking about how to thank you these past few days," Happy Baby said, breaking the silence first.
"Don't say that. We're comrades-in-arms; we should help each other," Lin Mu said.
"Alright, enough talk. I'll go find some materials and make a few whistles first," Happy Baby said and left.
"Lin Mu, between the bird language and the whistles, what exactly are you doing?" Zhuang Yan asked curiously.
"What's the most important thing coming up for our military region?" Lin Mu asked.
"The military exercise, of course. But is there any logical connection between the exercise and whistles?" Zhuang Yan asked, puzzled.
"There's no logical connection."
"But think about it: we're conducting the exercise in the mountains and forests. What would happen if we used whistles to transmit intelligence in bird language?" Lin Mu said.
"Good lad, that's a great idea. Let's hear the details." Lin Mu was startled; he hadn't expected Company Commander Miao to be there as well.
"Company Commander Miao, Platoon Leader Chen," Lin Mu said, turning around and saluting.
"Lin Mu, your idea just now was good. Can you go into more detail?" Company Commander Miao said with a smile.
"Uh, Company Commander Miao, this is just an immature idea of mine," Lin Mu said.
"That's fine. If you speak it out and we discuss it, it'll become mature," Company Commander Miao said.
"Company Commander Miao, I wonder if you've noticed the news about the Electronic Countermeasures Regiment in the military newspaper?" Lin Mu asked.
"No, why?" Company Commander Miao asked.
"Assuming the Electronic Countermeasures Regiment participates in this exercise, setting aside whether they're on our side or not, one thing is certain: they will definitely play a role in the military exercise by jamming either our or the enemy's electronic signals."
"If they jam the enemy's signals, we won't get any useful information."
"If they jam our signals, then our message transmission..."
Lin Mu didn't finish his sentence, but the meaning was already clear.
"So you came up with using bird language to transmit messages," Company Commander Miao said.
"Yes. In my vision, if we can use bird language to transmit intelligence, the security aspect alone would be sufficient, not to mention anything else," Lin Mu said.
"Alright, I approve this. We'll start a pilot program in your First Platoon first. I want to see what kind of role it can play in this military exercise," Company Commander Miao said, looking at Platoon Leader Chen.
Lin Mu really hadn't expected such a pleasant surprise.
Talk about good deeds being rewarded.
This was exactly it.
No wonder there's a saying: 'Do good deeds and don't worry about the future.'
He helped Happy Baby with tutoring, Happy Baby knew this and wanted to thank him by making some whistles, which led to the encounter with Company Commander Miao, who then gave his full support.
The logic was sound.
With the support of Company Commander Miao and Platoon Leader Chen, and without delaying their training...
Lin Mu, Happy Baby, and Zhuang Yan gathered every day. If they weren't tutoring Happy Baby in chemistry, they were learning bird calls from Lin Mu.
Or they would pull in Platoon Leader Chen or Old Cannon to compile a Bird Language Codebook.
How long or short each sound was, where to pause, which part was high-pitched, which part was low, which part was melodic—and what each represented.
All sorts of things, too many to list.
Lin Mu wrote down everything he knew and practiced every day in his spare time.
Because of the daily practice and the help of the whistles, never mind the First Platoon, the entire Reconnaissance Company could hear bird calls.
After a while, some people in the Night Tiger Reconnaissance Company began calling them the three 'Birdmen.'
Since it started suddenly, all of this was accomplished through the collective effort of the 'three bunglers'—Lin Mu, Happy Baby, and Zhuang Yan—along with Platoon Leader Chen or Old Cannon, who were occasionally roped in to act as advisors.
For ease of reference, Lin Mu gave it a name that was both down-to-earth and easy to understand.
Bird Language Code!
After more than ten days of effort by the group, it was finally completed one week before the exercise was set to begin.
To test the Bird Language Code, Lin Mu specifically went to Company Commander Miao and asked him to write a fictional piece of intelligence, inviting the Commander to personally participate in the test.
"Happy Baby, our test is here," Lin Mu said to Happy Baby after returning to the dormitory with a piece of paper.
