With the loudspeaker made by Li Tai, Li Zexuan left the workshop and planned to go home to prepare for a trip to the Xuanjia Army camp tomorrow!

He asked Li Tai to try to make a loudspeaker, not only to lay the foundation for the future invention of the telephone, but also to use the loudspeaker in the army!

In ancient times, there were no loudspeakers and no walkie-talkies. Large-scale corps operations often used the golden drum banner to convey the command of the generals. For example, drum drums, this war in the Cold Weapons Age is not just to cheer, but to deliver orders. You must know that tens of thousands of people are in formation, and it is not an information age. Being able to control soldiers is the basis of combat. Soldiers who do not understand the golden drum banner of their own army will often end up miserably because they cannot afford to raise the flag and press People who don't pay the flag, don't advance after hearing the drum, and don't retreat when the money is heard, are usually beheaded.

In fact, regardless of the mobilization of hundreds of thousands of horses in ancient wars, there were not many soldiers, and auxiliary soldiers and civilian men accounted for the vast majority. In the Song Dynasty, there were not many dynasties that raised the Forbidden Army and pigs. At the beginning of the Song Dynasty, 200,000 Forbidden Army could fight in the South and the North.

In history, the battles of more than 300,000 main forces were basically more defeats than less victories. To give a few examples, the first was the Battle of Feishui. 830,000 were defeated by the 80,000 Beifu army before they were assembled. The second is that the result of Emperor Yang's conquest of Goguryeo is self-evident. The third is the defeat of the Nine-Jie-degree siege of Yecheng in the Anshi Rebellion. The fourth is the 200,000 defeat of the Song Army in the Battle of Song Jin Fuping!

The above is basically a battle that wins more with less. Although the main reasons for failure are different, it is indeed unavoidable that the coordination and communication of the large army is inevitable. If there are too many frontal concentration forces, once it is defeated by points, it is extremely easy to cause defeat. .

Therefore, there are so many battles in the history of our country that win more with less, not without cause. Mainly elite, with a small number, but a flexible command of the army allows the generals to exert their abilities. For example, in the battle between Li Er and Dou Jiande in the early Tang Dynasty, Li Shimin defeated 100,000 enemies with a dissatisfaction.

Therefore, in frontal battles in later generations, it is basically a strategy that both sides use separate and combined attacks during contact operations. Although the total number of participants is large, there are few more than 50,000 on a battlefield, because 50,000 are basically sound and light. The limit of signal propagation. Therefore, in ancient times without loudspeakers or walkie-talkies, the generals on the battlefield relied on the golden drum banner and the tacit understanding and experience of each other. Whoever carried out the fighting intention better would win.

But with a loudspeaker it is completely different! This thing can transmit the combat instructions issued by the generals very far, and can maximize the tacit understanding of the various small groups! In real large corps operations, the battlefield situation is often complicated and requires tactics to be adjusted at any time. It is simply unrealistic to rely solely on the golden drum banner to send orders. As for the use of messengers to pass orders, the timeliness of combat formulation cannot be guaranteed!

Imagine that if the general's command is transmitted by a loudspeaker during a war, not only can it be transmitted far, but compared to the golden drum flag, the loudspeaker can also transmit more complex combat commands!

If you are worried that the combat instructions will be heard by the enemy generals, you can set up a complete and detailed tactical secret order in advance. In this way, you can not only maximize the cooperation between the corps, but also prevent the combat deployment from being heard by the enemy generals. To, it can overwhelm the opponent in momentum!

After all, sometimes loud voice is also an advantage, isn’t it?

While walking, while planning the application of the loudspeaker in his mind, Li Zexuan suddenly felt something was wrong, because at this moment the sky was suddenly dark!

Li Zexuan couldn't help raising his head and looking towards the east sky, he saw small black dots with wings all over the sky, covering the sky and obscuring the sun. It was mid-afternoon and the sun was still in the southwest, but these small black spots The dots are overwhelming, and there is a tendency to cover the entire sky!

Compared to the total solar eclipse two months ago, the sight of the sky being gradually eroded by countless small black spots is undoubtedly even more terrifying!

"The plague of locusts is coming!"

In an instant, Li Zexuan reacted, isn't this the great locust plague in June of the second year of Zhenguan recorded in the history books?

Although Li Zexuan, a modern person, has seen locusts, he has never seen locust plagues, because people of his time like to eat fried locusts, and the locusts in nature are not enough for foodies, so that there is a business of artificially raising locusts. How could there be a locust plague!

This is the first time he has seen such a large-scale locust plague since his two lives. He said in his heart that it is impossible not to be surprised! The dense and overwhelming locusts are definitely a painful torture for people with intensive phobia. Li Zexuan does not have intensive phobia, but after seeing the locusts flying in the sky and covering the sky, he still bears it. Can't help scalp tingling!

There are too many locusts!

When he used his poor historical knowledge and Li Er to predict that there would be a plague of locusts in the second year of Zhenguan, he had never expected the plague of locusts to come so suddenly and so fiercely!

Where is the locust plague! This is a bit like those black and overwhelming bugs in some apocalyptic movies that Li Zexuan has seen in his previous life. This is a common catastrophe!

Even though the Tang Dynasty has made perfect preparations for the plague of locusts, Li Zexuan's heart can't help but shake at this moment. Can the preparations made by the Tang court really survive this plague of locusts?

"Locust plague! This is a locust plague!"

"God's punishment! Heaven's punishment!"

"God! Old man, my crops!"

"The locust **** is furious, the common people are catastrophe!"

The people who were still farming in the fields couldn't help but panic when they saw this terrifying scene of catastrophe. Some panicked and fled to their homes; some grabbed the ground with their heads and cried bitterly; some knelt on their knees and prayed for God!

The world, which was still plain the moment before, was immediately replaced by a large-scale panic. It is not to blame for the fragility of people's hearts, but the scale of this locust plague is too terrifying!

Li Zexuan estimated that if all the locusts flying on his head were caught, it would be a thousand catties, not to mention that this large area of ​​sky would be full of black locusts!

One can imagine how terrifying this number is!

"Lord Hou, please go home as soon as possible!"

Pang Feiji and other guards guarded Li Zexuan as if they were facing the enemy, and waved their swords to drive away some low-flying locusts. Seeing the people in the surrounding fields chaotically, Pang Feiji turned his head and shouted at Li Zexuan.

Li Zexuan had already recovered from the initial horror at this time, and he blankly said, "Go to Yunshan! Feiji, you immediately take people to the county office and let the county magistrate He come over, and give it to my father, my mother, and my wife. Tell me peace! Besides, you will send someone to invite Uncle Hu, Erye Liu and Qingfeng Liu! Immediately! Immediately!"

Pang Feiji turned his head and looked at the three brothers beside him. Li Zexuan usually only takes three or four people when he goes out on weekdays. Today is no exception, so he said anxiously to Li Zexuan, "But, after I leave, who will come? Protect Lord Hou?"

Li Zexuan said calmly, "Protect? Just a few locusts, do you still need your protection? The people who really want to protect are the people of Lantian County. You have to say more, go and return quickly!"

Pang Feiji wanted to say that the people in panic might inadvertently hurt Li Zexuan, but after thinking of Li Zexuan’s martial arts that shocked the world, he decisively did not say these words, but clasped his fist and said, "Subordinates follow the order, and ask Master Hou himself. Be careful!"

After all, he waved his hand and took a guard straight to Lantian County, while the other two guards went to Hanjiazhuang and Meicun separately!

"The locust plague is coming! The locust plague is coming!"

"My family's crops! Summer harvest in a few days!"

"Run! So many locusts are going to eat people!"

"Run! Run!"

More than twenty prefectures and counties around Chang'an City are all in a panic at this moment. Unlike the solar eclipse, the destructive power of the locust plague on the world is obvious. In addition, the legend of the locust **** has been circulating among the people. scared!

Some people in Zhuangzi even set up incense tables at the head of the village, kneeling down and praying that the locust **** will hurry down and let the locust plague go quickly!

"Your Majesty! Your Majesty! It's not good! Locusts, all the locusts are overwhelming! Chang'an City and dozens of surrounding prefectures and counties are all shrouded in locusts that obscure the sky. The land where the locusts pass, there will be no grass!"

The quiet Ganlu Temple suddenly ran into an **** at this time. The news brought by the little **** was like thunder on the ground, and it blasted into the Ganlu Temple!

Li Er suddenly got up from the dragon couch with a "jerk", he said with a serious face, "What are you talking about? A locust plague broke out near Chang'an?"

"Yes! Your Majesty! Now the people everywhere are fleeing in panic. The crops in the fields that are about to mature are all covered with dense locusts, and there are many locusts flying in the sky, covering the sky!"

The little **** was terrified at the moment, and he must have seen such a terrifying sight for the first time in his life!

Li Er's heart was stunned, as he was about to speak, a little **** walked in outside the hall, and the **** said anxiously, "Report~! Your Majesty! Qizhou Governor is in a hurry! A large-scale locust plague occurred in Qizhou, and it was overwhelming. The locusts are flying towards the capital!"

Hearing this, Li Er furiously said, "Bastard! The locusts have all arrived in Chang'an City. How did his Qizhou governor's eight hundred li rush to reach the palace?"

Zhao Song whispered beside Li Er at this time, "Your Majesty calm down, Qizhou is more than 1,800 miles away from Chang'an, even if it is 800 miles urgently, it still has to run for several days! And the source of locusts is definitely not limited to Qizhou. In one place, otherwise there wouldn't be so many locusts!"

At this time, Li Er woke up from his anger. He brushed his sleeves and said in a deep voice, "Quickly go up to the tower to ring the Jingyang Bell, and urgently summon a hundred officials to the court! Today, a noon is added!"

Just a few hours after the early dynasty ended, Lao Li came up with another noon dynasty, but it was also impossible. The locust plague was too big, and it was necessary to coordinate and cooperate with the six departments of the court to effectively fight the disaster!

As for this Jingyang bell, it began in the Southern Dynasties. Emperor Qi Wu used the palace to ignore the sound of the Duanmen drum and placed the bell on the Jingyang Tower. The palace people heard the bell and got up early for decoration. Later generations called it "Jingyang Bell". ". Jingyang bells ring every day, announcing the beginning of the early dynasty, and a group of officials and officials arrange their shifts in the hall. All subsequent dynasties and generations are subject to the Jingyang bell.

"Here~!"

A servant in the hall quickly gave his orders.

Li Er thought for a while, then looked at Zhao Song, and said, "Zhao Song, you should leave the city immediately, go to Lantian County, and invite Yonganhou into the palace!"

Since last year, Li Zexuan has helped Li Er solve countless troubles, so much so that Li Er is now somewhat dependent on Li Zexuan, and will subconsciously think of Li Zexuan whenever something happens!

Of course, on the other hand, it was Li Zexuan who made the prediction of the locust plague last year. As the saying goes, the person who needs to tie the bell to untie the bell. Now that the plague of locusts is coming on schedule, of course, Li Zexuan should be invited over to discuss the major disaster relief together!

Zhao Song had a solemn expression, and said, "Old slave abides by the decree!"

Having said that, he didn't dare to delay any longer, and he just stepped out of the hall!

"Clang~! Clang~! Clang~!"

After a while, there were dull and melodious bells and drums on the tower of the Imperial City next to the Vermillion Bird Gate, and the huge sound gradually spread throughout Chang'an City!

In Chongrenfang, Changsun Wuji heard the bells and drums, his expression changed, and he said, "Come on! Get ready for horses! The old man is going to the palace!"

A woman beside Changsun Wuji said strangely, "Master, just finished the morning court this morning, what are you doing in the palace now?"

Changsun Wuji anxiously explained, "Madam, listen! The Jingyang bell ringing indicates that something major has happened in the palace. The last time the Jingyang bell sounded in the afternoon was the year before last!"

The year before last, it was nine years of Wude, the change of Xuanwu Gate!

The lady's complexion changed ~www.ltnovel.com~ and quickly said, "That concubine changes clothes for the master!"

Changsun Wuji nodded. He looked up at the black locusts in the sky, and whispered, "The locust plague is now in this world. Your Majesty, this should be an urgent call for hundreds of officials to enter the palace to discuss countermeasures!"

Above Yunshan, the meeting room of Yanhuang Academy.

Li Zexuan sat in the first seat, He County Majesty, Hu Hanyun, Liu Erye, and Liu Qingfeng sat down in turn. Somewhat strangely, Li Gang, Yan Silu, and Ma Zhou were also present at the Yanhuang Academy!

Li Zexuan's face was sinking. After seeing the crowd, he said solemnly, "The locust plague is here, and you must have seen it. Some people regard the locust plague as the locust god's wrath, what do you think?"

Old Hu grinned his neck and said, "Master, I am a little student, but I will only respect the heaven and the earth in my life, and disrespect the ghosts and gods. What kind of **** and locust god, it harms our crops, we should destroy it! Dissatisfied with the young master, you say Last year, Lao Hu had a few dishes of Feihuang Tengda!"

Liu Erye nodded and said, "The little nonsense is right! Master, the locust plague is very serious now, and the crops in the ground will be harvested in a few days, but at this time there is such a large-scale locust plague. Master, if you are good As long as the locusts can be killed, Liu Wanshan will not dare to do it!"

Liu Qingfeng and He County magistrate are both scholars, not like Liu Erye and Lao Hu, who are as reckless as Liu Erye and Lao Hu. They laughed and said, "Yes! We all listen to Houye!"

Li Zexuan nodded, and said with a serious face, "Okay! I don't believe in any locust gods. Even if there is a locust **** in this world, he is also an evil **** who poisons creatures, and he can't kill him! The next few things I have arranged , You must keep in mind and strictly enforce it, because this is a major event that concerns the life and death of more than 80,000 people in Lantian County!"
