Tongchuan Prefecture is directly east of Chengdu Prefecture, so there is only more than 200 miles from Qixian County to Chengdu, and there is a direct official road.

Sichuan is a large basin, and Chengdu is a plain terrain, so the road is not particularly difficult.

However, the speed of the reorganized army cannot be compared with that of the original Red Lady Division. Even with later military rations as extra meals and watching movies as spiritual rewards, the team can only travel more than fifty miles a day.

At noon that day, Zhu Aela returned to her old house in Zhulin and saw Hao Guangming coming in with a cardboard box.

Seeing Zhu Ailao, Hao Guangming smiled and said: "You came back just in time, the intercom has finally arrived."

Before, when Zhu Aelao was in Langzhong, Hao Guangming said that he wanted to buy a walkie-talkie so that the matchmaker department could have instant communication capabilities.

As a result, when he was about to purchase it, he learned that to use a walkie-talkie, you must apply and obtain qualification approval from the relevant departments.

Because the unauthorized use of walkie-talkies interferes with the communication of other walkie-talkies within the range, it may cause a major accident.

In countries with relatively strong control, such as Great China, the frequencies of walkie-talkies are managed uniformly.

This can minimize the occurrence of related accidents.

According to what Hao Guangming had thought before, if he were to buy hundreds of units at a time, serious sellers would have to understand his qualifications before shipping.

Although it is not particularly difficult to apply for qualifications such as walkie-talkies, Hao Guangming could not find a reason to use hundreds of walkie-talkies at the moment, such as carrying out large-scale projects, opening a large hotel, organizing a large-scale outdoor adventure, etc.

In the end, Hao Guangming had no choice but to do the next best thing. As a walkie-talkie enthusiast, he applied for the qualification to use several walkie-talkies through other channels, and purchased four walkie-talkies with longer talking distances.

As for the walkie-talkie repeater, it was more difficult to apply for the qualification to use it, and Hao Guangming couldn't get it at the moment.

However, the four walkie-talkies he bought came with their own micro-repeater stations. Using the four walkie-talkies together can effectively extend the communication distance.

Seeing Zhu Yurao looking over curiously, Hao Guangming put down the cardboard box, took out the walkie-talkie from inside, and started explaining.

"General walkie-talkies are subject to various interferences here, and the communication distance is only a few miles, and it is difficult to exceed ten miles.

But there are also some walkie-talkies with higher power, whose communication distance can reach dozens of miles.

Like the four units I bought, the maximum power can reach 18 watts, and the longest communication distance here can reach 40 miles.

Daming's radio environment is excellent, with almost no interference, and the communication distance will only be longer, perhaps up to 50 miles.

In addition, these four walkie-talkies all carry micro repeaters, which can continue to transmit radio waves to each other. If necessary, they can even be used for long-distance communication of more than a hundred miles."

Zhu Ya'ao found that she couldn't understand most of Hao Guangming's words, so she asked directly: "Is it easy to learn how to use this walkie-talkie?"

Hao Guangming smiled and said: "Of course it's easy. With your intelligence, you should be able to master it in half an hour."

Next, Hao Guangming took out the meal he had packed back from the county seat and taught Zhu Yurao how to use the walkie-talkie while eating.

After lunch, Zhu Aona took a batch of supplies to Daming, and gave the troops an extra quarter of an hour to rest.

Then he came back to continue studying with Hao Guangming.

After seeing that Zhu Yuluo had basically mastered the use of walkie-talkies, Hao Guangming said: "A walkie-talkie is actually a type of radio station. When you settle down in Chengdu, you can find some skilled craftsmen and people who are good at studying strange techniques.

As long as you bring the technology to make radio stations from here, as well as the materials and parts that Ming Dynasty is not capable of manufacturing, you can directly make radio stations in Ming Dynasty.

That way we won't be restricted by our qualifications and can communicate over longer distances."

"Yeah." Zhu Ayao nodded.

After living with Hao Guangming for so long and understanding so much modern knowledge, she already knew that craftsmen were very important. She also knew that modern times relied on the development of science to become so much more developed than the Ming Dynasty.

Therefore, after Ming Dynasty has a stable territory, it will definitely develop science, industry, and attach importance to craftsmen and other related talents.

"Is this a walkie-talkie?"

The red lady carefully took a walkie-talkie from Zhu Yuluo's hand and looked at it curiously.

The main body is a palm-sized black box with three strips slightly thinner than chopsticks. The one on the right is the shortest and the one on the left is the longest. It is more than a foot long when pulled out.

Li Yan, Fei Zhen'e, Fang Zhenghua and others also came to watch curiously.

Zhu Aelao took the opportunity to talk about how to use the walkie-talkie.

Li Yan, Hong Niangzi, etc. were all smart people. They followed Zhu Yuyao and learned as they went. Although they didn't learn as fast as Zhu Yuyao, they still basically learned it after an hour.

Immediately, the red lady took a walkie-talkie and chased the cavalry troops in front.

Here, Li Yanze also held a walkie-talkie, turned it on according to what he had learned, and waited anxiously.

About a quarter of an hour later, the intercom signal light came on and there was a slight sound.

Then the clear voice of the red lady came out.

"Li Yan, Li Yan, I am the red lady, can you hear me?"

Li Yan subconsciously wanted to answer directly, but then he remembered the process taught by Zhu Aao.

So she said nervously: "Red Lady, Red Lady, I am Li Yan, I can hear you."

"Great! This baby really works! I have already caught up with the cavalry, and I am more than ten miles away from you!"

Through the voice on the intercom, you can hear that the matchmaker is extremely excited.

Li Yan was also very excited, like a child.

But he was better at cultivating qi. He controlled his emotions and asked, "How is the situation ahead? You haven't encountered any enemy situation, have you?"

"No, even some common people in the fields ran away like rabbits when they saw us."

"Then you can continue marching. Don't always use the walkie-talkie to talk to me if you have nothing to do. Be careful to save power."

"I know."

Seeing Li Yan put away the walkie-talkie and carefully fastened it to the leather belt given to him by Zhu Yuyao, Fang Zhenghua, Liu Xiaolian and others all looked envious.

They also wanted to try out the walkie-talkie, but they felt it was not good to treat a useful treasure like a toy.

For a moment, he could only show his envious eyes.

Seeing this, Zhu Yasuo smiled and said generously: "You have to actually use this walkie-talkie to know whether it is good or not. Since there are two more here, you can try it out.

Let all the generals at the level of General Qian in the army also give it a try, lest they don't know how to use it when they need it in a war."

Li Yan and others immediately paid homage to Zhu Aona: "Thank you, Your Highness!"

···

Chongzhen's seventeenth year, July 3rd.

Chengdu.

News of Zhang Xianzhong's attack on Chongqing has spread. It can be expected that Chengdu will be Zhang Xianzhong's next target, so people in the city are already panicking.

All civil servants and generals knew that it was necessary to strengthen the city defense and train troops and horses to make it possible to save Chengdu.

However, there have been many natural disasters in Sichuan in recent years. Coupled with the corruption of officials and the series of battles with Zhang Xianzhong's department some time ago, all public treasuries have been depleted of money and food.

In the morning of this day, Liu Zhibo, the censor of the patrol, came to visit the Prince of Shu's palace with two of his entourage under the bright sun.

After the report, the disciple said: "Liu Xun, please go back. The king has given orders. It's hot and he doesn't want to see anyone."

What does the hot weather have to do with meeting people?

Liu Zhibo laughed angrily, his beard and hair trembling.

He didn't bother to talk nonsense to the disciples of Prince Shu's palace, so he just drew his sword.

Seeing this, the gatekeepers and the palace guards behind became nervous and asked, "Is Liu Xunjian planning to commit murder in the palace of the Prince of Shu?"

Liu Zhibo's eyes showed a ruthless look, and he shouted loudly: "If the King of Shu does not meet you today, I will kill myself here!"

The doorman and guards were shocked when they heard this.

If the patrol censor committed suicide in front of the gate of Prince Shu's palace, the matter would be unclear.

So Menzi hurriedly said: "Liu Xun, please don't be impulsive. I will report it right away."

After saying that, he hurried in and ran in.

About a quarter of an hour later, a steward from the palace came over with the disciple and said, "What's wrong with Liu Xun? Please come in."

Then, Liu Zhibo followed the steward for nearly half a quarter of an hour in the Prince of Shu's palace, and then he met Zhu Zhishu, the contemporary King of Shu, in Chengyun Hall.

The fragrance of wine and powder lingers in the air inside the hall, and more than a dozen ice cubes are placed everywhere, making the Chengyun Hall cool even in the hot summer.
