"Call the bandits!"

"Rob the bandits!"

"I'm a bandit!"

"Super double!"

"Super double!"

"Damn it! Lin Hao! The cards in your hand are so bad, why do you double them so much?"

"Qingque, didn't you realize that when you shout super double, it will bring you several times more happiness?"

"I… "

"Haha! Did I say it right? Qingque, come on, keep going! If you lose a few more pennies, you can get several times more happiness. Why not?"

In the first month of this year, Li Tai suddenly had a whim and wanted to meet Tiedan's new "apprentice", so a "charity gambling king, super free gift" card game was staged in the Lin family's backyard. Li Tai and Li Tai, who had never met each other, Lin Hao inexplicably became a pair of close friends because of this, but... Lin Hao at that time was not so thin~!

Mainly because of this reason, Li Taicai didn't recognize him the first time! Of course, there is also the factor that the two have not seen each other for several months.

"Wow~! Qingque? Is it you? You... why are you fat again?"

Lin Hao said with surprise when he saw Li Tai next to Li Zexuan.

As expected of good friends, they stab each other and hurt each other as soon as they meet!

Li Zexuan almost laughed out loud and said to himself: If you can speak, just speak more!

Li Tai, on the other hand, looked like he had eaten shit. He spat out the fragrance angrily: "Damn! I haven't seen you for several months, Lin Hao, how come you don't know how to spit out words? What? You were not convinced when you lost last time. ?Want to fight again~?"

This anger was more because Lin Hao suddenly lost a lot of weight for some reason and therefore left the fat house team. Li Tai felt a little lonely and lonely from it!

Although in the Tang Dynasty, fatness was regarded as beauty, but fatness must have a certain standard, and following Li Zexuan for so long, Li Tai also learned that if a person is too fat, many physical problems will occur. The military training last year did make Li Tai lose a lot of weight, but with the comfortable study life this year, especially since he doesn't like sports very much and always likes to stay in the classroom or laboratory to study knowledge, he also gained weight quickly. It bounced back! Now he has basically reached his "peak level"!

In fact, Lin Hao never knew Li Tai's true identity, but even if he knew it, with his innocent and straightforward temperament, he would not be obedient or flattering to Li Tai because of this. At this time, he held his head high and showed no weakness. The ground fired back:

"Who lost~? I didn't lose last time! I remember that only my husband won last time, and we both lost! Huh? My husband is here too~? I've met Mr. Han!"

While talking, Lin Hao finally saw Tie Dan standing behind Li Zexuan. Although he could call Tie Dan by his first name because of his good relationship, outside, he still had to address Tie Dan as Mr. Tie Dan. After all, respect for teachers is important. This is a rule that everyone must abide by in this era!

"Um!"

Tiedan nodded lightly and said nothing more, because Li Zexuan was still standing in front of him!

"Lin Hao, it's neither noon nor night yet, what are you doing at your Longmen Inn~?"

Li Zexuan, who had been standing aside in silence for a long time, finally spoke.

"Uh! This is it!"

After listening to Li Zexuan's question, Lin Hao immediately straightened his expression and replied: "Returning to Master, this disciple will take the entrance exam for Yanhuang Academy tomorrow morning. Chang'an City is too far away from Yunshan, so we can only stay at Longmen Inn~! "

"Oh! I remembered it! You are the apprentice Lin Hao that Tiedan accepted before, right?"

Cheng Chumo, who had been stunned for a long time, finally came to his senses. He patted his head and laughed loudly.

"Yes, yes! It's me! It's me!"

Lin Wenhao nodded quickly in response.

"Haha! You also want to take the entrance exam for Yanhuang Academy? OK, OK! I remember when I, Old Cheng, came out on top in the Yanhuang Academy's admissions exam and shone brightly! As Tiedan's apprentice, you have to work hard! I'll wait until you get in. In the academy, tell me your name, Old Cheng, when you see anyone, and I’ll make sure no one dares to bully you!"

It's rare to meet a "youngster", Cheng Chumo immediately started bragging.

"Pa~!"

Facing the extremely enthusiastic Cheng Chumo, Lin Hao was at a loss. Just as he was about to express his thanks, a palm fell heavily on the back of Cheng Chumo's head. Someone screamed in pain, but Li Zexuan cursed angrily: "You kid, you are doing all this." Don’t show off your poor grades in the academy here, you don’t think it’s embarrassing, but Uncle Cheng does too~!”

Cheng Chumo looked at Li Zexuan with a resentful look on his face, wondering what happened to him bragging in front of the "newcomer"? It's not illegal

Li Ze You are so well prepared, as long as you perform normally, there will basically be no problem! Come on!"

No matter what, the chubby guy called him Master (although he never agreed), and those who should be encouraged should still be encouraged.

"Yeah! Thank you, Master! Well, Master, what do you mean by refueling? There is no cooking, so why do you need to refuel?"

With Li Zexuan's encouragement, Lin Hao's face suddenly became full of energy, but Li Zexuan's last words of "come on" made him a little confused.

"Uh! It's nothing! I just want you to work hard! Go back to the inn and rest!"

A trace of embarrassment appeared on Li Zexuan's face. He waved his hand and said quickly.

"Oh! Master, don't worry. I will definitely work hard. Oh, no, I will definitely work hard!"

Lin Hao clenched his fists tightly and responded loudly.

This look could be made into a WX emoticon in modern times!

… … … … … …

After bidding farewell to Lin Hao, Li Zexuan and his party left Lantian County. Cheng Chumo, Li Ke, Tiedan and others returned directly to Yunshan, while Li Zexuan took Li Tai to the scientific research base in the Qiquge New Workshop.

"Okay! If you have any problems, tell me today!"

In the laboratory, Li Zexuan found a stool and sat down, then looked at Li Tai and said.

In fact, from meeting Li Tai in the academy cafeteria this morning, Li Zexuan could feel the urgency in the little fat man's heart. As for what the urgency was, Li Zexuan guessed that it might be that Li Tai encountered some difficult problems in the "Killer Project" during this period. He needed help to solve the problem, so as soon as he sat down, Li Zexuan asked straight to the point.

"Hey! Chief Shan, look at something first!"

Li Tai did not answer Li Zexuan's question directly, but smiled, then turned and walked towards a cabinet in the corner. After a "dinging" sound, Li Tai moved out a box and cautiously said: "Chief, look, what is this?"

"What is this~?"

Li Zexuan looked at the few iron lumps and rubber-wrapped wires inside the box. He frowned and said with some doubts.

"Hey! Chief Shan, this is a telegraph machine that can transmit sounds! It's the latest invention of Mr. Mo Chui and I~!"

Li Tai smiled proudly, and while carefully moving the contents of the box to the experimental table, he turned to Li Zexuan and said.

The showoff in his tone was very obvious.

"A telegraph machine that can transmit sound~?"

Li Zexuan's heart moved, and he suddenly thought of a possibility. He couldn't help but said in surprise: "Qingque, have you successfully combined the telegraph machine and the loudspeaker~?"

More than a month ago, Qiquge Workshop successively manufactured the most basic electronic components such as resistors, capacitors, inductors, diodes, and transistors. At that time, Li Zexuan and Li Tai proposed an idea of manufacturing telephones. Through some simple circuits, To realize the conversion of sound wave-current-sound wave!

Although it sounds difficult, before Li Zexuan went north to exterminate the locusts, Li Tai and a group of teachers and students from the physics group of the academy created a simple acoustic-to-electrical conversion device - a loudspeaker. The telephone is one step closer!

Li Zexuan didn't expect that just after he came back from the north, Li Tai had already built the prototype of a telephone, but he didn't know the specific effect!

"Hehe! That's what it means, but this one is wired. It's similar to the telephone you told me about before, Chief Shan!"

Li Tai scratched his head proudly, and then asked with a hopeful look on his face: "Chief, do you want to try the effect?"

The look of hope on his face was just like that of a child who got perfect marks in the exam and longed for praise from his parents. This made Li Zexuan sigh. Who would have thought that the unruly little fat man would have such an obedient side now

"Of course I have to give it a try! Qingque, let's start!"

Li Zexuan did not "disappoint" Li Tai. He nodded and replied.

"good!"

Li Tai responded cheerfully, and then he skillfully took out instruments one after another from the box, handed a honeycomb-shaped cube to Li Zexuan's hand, and then he pulled another cube and walked out of the house.

The two people each hold a square, with a large iron box in the middle, and the three are connected with wires.

"Shan Zhang, I'm going to another room. You can see if you can hear me in a while~!"

Li Tai shouted and then went out. When he went out, he even closed the door!

"good!"

Li Zexuan responded and let Li Tai fiddle around.

"Chief! Chief! Can you hear me~? If you hear me, please answer! If you hear me, please answer!"

After a while, a dull sound came from the "cube" in Li Zexuan's hand!

This is authentic current sound transmission, not the kind of solid sound transmission that traditional telephones rely on! Li Zexuan was very sure, because he could still hear the intermittent "sizzling" sound of electricity from Li Tai's voice!

This proves that Li Tai indeed created the first generation telephone!

"I can hear it! I can hear it!"

After recovering from the surprise, Li Zexuan quickly picked up the cube and said excitedly to Li Tai on the other end: "Qingque, congratulations on completing a great invention. The history of mankind is very likely to be because of you." It was completely rewritten due to this invention!”
