With the megaphone made by Li Tai, Li Zexuan left the workshop, planning to go home and prepare, so that he could go to the Xuanjia Army camp tomorrow!

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

In ancient times, there were no loudspeakers, let alone walkie-talkies, and large-scale corps operations often used golden drums and banners to convey the generals' combat orders. For example, the beating of drums, in the war of the Cold Weapon Age, was not just for cheering, but for passing orders. It is necessary to know that tens of thousands of people are in a formation together, and it is not the information age, and being able to control soldiers is the basis of warfare, and soldiers who do not understand the golden drum banner of their own army will often end up very miserable, because they cannot afford to raise the flag, do not pay according to the flag, do not advance when they hear the drums, and do not retreat when they sound the gold, and so on, they will generally be beheaded.

In fact, don't look at the mobilization of hundreds of thousands of horses in ancient wars, among which there are not many soldiers, and auxiliary soldiers and civilians account for the vast majority of the number. There are not many dynasties like the Song Dynasty that raise forbidden troops and pigs, and it is the norm for 200,000 forbidden troops in the early Song Dynasty to fight in the south and in the north.

The war of more than 300,000 main armies in history is basically more defeated and less victorious, to give a few examples, the first is the Battle of Huangshui, 830,000 were defeated by the 80,000 Beifu Army before they were gathered, the second is that the results of Emperor Yang of Sui's expedition to Goguryeo are self-explanatory, the third is the defeat and loss of the battle of Yecheng in the siege of Yecheng in the Anshi Rebellion, and the fourth is the Battle of Songjin Fuping, where the Song army of 200,000 was defeated!

Although the main reasons for the defeat are different, the unavoidable reason for the poor coordination and communication of the large army during the battle is that the frontal concentration of troops is too large, and once the surface is broken by the point, it is extremely easy to cause a rout.

Therefore, it is not for nothing that there have been so many battles in the history of our country in which fewer won more. Mainly elite, there are fewer troops, but the command of flexible armies allows the generals to use their abilities. For example, in the battle of the Tiger Prison between Li Er and Dou Jiande in the early Tang Dynasty, Li Shimin broke the enemy with less than 10,000 people.

Therefore, in the later generations, when fighting head-on, it was basically a strategy of both sides using separate attacks when they were in contact operations, and although the total number of participants was large, it was rare to have more than 50,000 on a battlefield, because 50,000 people was basically the limit of sound and light signal propagation. Therefore, in ancient times when there were no loudspeakers or walkie-talkies, on the battlefield, the generals relied on the golden drum banner and the tacit understanding and experience between each other, and whoever carried out the battle intention better could win.

But with a megaphone it's completely different! This thing can transmit the combat orders issued by the generals far away, and can give full play to the tacit understanding between the previous small corps! In a real large-scale corps operation, the battlefield situation is often complicated and requires the adjustment of tactics at any time, and it is simply unrealistic to rely solely on the golden drum banner to give orders.

Just imagine, if the general's instructions are transmitted by a loudspeaker during a war, not only can they be transmitted far away, but also compared with the golden drum banner, the loudspeaker can also transmit more complex combat commands!

If you are worried that the combat command will be heard by the enemy general, you can set up a complete and detailed set of tactical secret orders in advance, so that not only can the tacit understanding between the corps be brought into full play, but also prevent the combat deployment from being heard by the enemy general, and even more can overwhelm the opponent in terms of momentum!

After all, sometimes loud voices are an advantage, aren't they?

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

Li Zexuan couldn't help but raise his head and looked towards the eastern sky, and saw small black dots with wings all over the sky, covering the sky and the sun.

Compared to the total solar eclipse two months ago, the scene of the sky being gradually eaten away by countless small black dots is undoubtedly even more terrifying!

"The plague of locusts is coming!"

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

As a modern person, although Li Zexuan has seen locusts, he has never seen locust plagues, because the people of their time liked to eat fried locusts, and the locusts in nature are not enough for foodies, so that there is also a business of raising locusts artificially, how can there be a locust plague!

It was the first time in his two lives that he had seen a plague of locusts of this magnitude, and he said in his heart that it was impossible not to be surprised! The dense and overwhelming locusts are definitely a painful torture for people with dense phobia, Li Zexuan does not have dense phobia, but after he saw the locusts flying in the sky and covering the sky, he still couldn't help but feel numb on his scalp!

There are so many locusts!

In the past, when he relied on his poor historical knowledge to predict to Li Er that there would be a locust plague in the second year of Zhenguan, he never thought that the locust plague would come so suddenly and so fiercely!

Where is this locust plague! This is a bit like the black and oppressive bugs in some post-apocalyptic movies that Li Zexuan watched in his previous life, this is a catastrophe!

Even though the current Datang Dynasty has made all preparations for the locust plague, Li Zexuan's heart can't help but be a little shaken at this moment, can the preparations made by the Tang Dynasty really withstand this locust plague?

"Locust plague! This is a plague of locusts! ”

"Divine punishment from heaven! Divine punishment from heaven! ”

"Oh my God! My crops, old man! ”

"The locust god is wrathed, and the common people are catastrophic!"

The people who were still plowing in the fields could not help but be terrified when they saw this terrible scene of catastrophe, and some people panicked and fled to their homes; Some people grabbed the ground with their heads and wept bitterly; Some people fell on their knees and folded their hands in prayer to God!

The world that was still ordinary a moment ago was suddenly replaced by a large-scale panic, not to blame the fragility of people's hearts, but the scale of this locust plague is too terrifying!

Li Zexuan estimated that if he caught all the locusts flying above his head, he would have thousands of catties, not to mention that this large area of the sky was full of black locusts!

One can imagine how terrifying this amount is!

"Please go home quickly!"

Pang Feiji and the other guards guarded Li Zexuan as if they were facing a great enemy, and waved the sword in their hands to drive away some relatively low flying locusts, seeing that the people in the surrounding fields were in a mess, Pang Feiji hurriedly turned his head and said loudly at Li Zexuan.

Li Zexuan had already recovered from the initial shock at this time, and he commanded expressionlessly, "Go to Yunshan!" Feiji, you immediately take someone to the county government to let He County Order come over, and by the way, report the safety of my father, my mother and my wife! In addition, you have someone to invite Uncle Hu, Second Master Liu and Liu Qingfeng over! Immediately! Right away! ”

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, and today is no exception, so he said to Li Zexuan urgently, "But, after I leave, who will protect Master Hou?" ”

Li Zexuan said very calmly: "Protection? Just a few locusts, do Benhou still need your protection? What we really want to protect is the people of Lantian County, don't say more, go back quickly! ”

Pang Feiji wanted to say that the panicked people might inadvertently hurt Li Zexuan, but after thinking of Li Zexuan's shocking martial arts, he decisively did not say these words, but hugged his fists and said, "Subordinates obey the order, please be careful yourself!" ”

After that, he waved his hand and went straight to the county seat of Lantian County with one guard, and the other two guards went to Hanjiazhuang and Meicun separately!

…………………………………

"The plague of locusts is coming! The plague of locusts is coming! ”

"My crops! The summer harvest will be in a few days! ”

"Run! So many locusts are trying to eat people! ”

"Run! Come on! ”

More than 20 prefectures and counties around Chang'an City, all of them are in a panic at this moment, different from the solar eclipse, the destructive power of the locust plague to the world is obvious, and the folk have been circulating the legend of the locust god, the people are not afraid!

Some of the people of Zhuangzi even set up incense tables at the head of the village, kneeling on the ground and praying that the locust god would quickly send down a divine decree to let the locust plague leave quickly!

"Your Majesty! Your Majesty! Oh no! Locusts, all locusts! Chang'an City and dozens of surrounding states and counties are all shrouded in locusts that cover the sky and the sun, and the places where the locusts pass through are not a single grass! ”

In the quiet Manna Palace, a eunuch suddenly ran in at this time, and the news brought by the little eunuch was tantamount to thunder on the ground, and it exploded in the Manna Palace!

Li Er suddenly got up from the dragon couch, and he said with a serious face, "What did you say?" A locust plague broke out near Chang'an? ”

"Yes, yes! Your Majesty! Now the people everywhere are fleeing in panic, and the fields are full of locusts on the crops that are about to ripen, and there are many locusts flying in the sky, covering the sky and the sun. ”

The little eunuch was extremely frightened at the moment, presumably it was the first time in his life that he had seen such a terrifying scene!

Li Er's heart sank, and he was about to speak, when a little eunuch walked in outside the hall, and the eunuch hurriedly said, "Report~!" Your Majesty! Qizhou Thorn History 800 miles expedited! There is a large-scale locust plague in Qizhou, and the locusts are flying in the direction of the capital! ”

When Li Er heard this, he was furious and said, "Bastard! This locust has arrived in Chang'an City, how did he rush to the palace for eight hundred miles of Qizhou Thorn History? ”

Zhao Song whispered beside Li Er at this time: "Your Majesty, stop your anger, Qizhou is more than 1,800 miles away from Chang'an, even if it is 800 miles in an emergency, it will take several days to run!" And the source of locusts must be more than one in Qizhou, otherwise there would not be so many locusts! ”

Li Er woke up from his anger at this time, he flicked his sleeves, and said in a deep voice, "Quickly go up to the city tower and ring the Jingyang bell, and urgently summon hundreds of officials to the court to discuss matters!" Add a noon dynasty today! ”

A few hours after the end of this early dynasty, Lao Li made another noon dynasty, but this is also a helpless thing, the locust plague is too big, and all departments of the six departments of the court must cooperate in order to fight the disaster efficiently!

As for this Jingyang bell, it began in the Southern Dynasties period, Emperor Qi Wu did not hear the sound of the end door drum leakage in the palace depth, put the bell on the Jingyang floor, the palace people heard the bell, got up early to decorate, and the descendants called it "Jingyang Bell". The Jingyang bell rings every day, announcing the beginning of the early dynasty, and the ministers and hundreds of officials go to the palace to arrange shifts in the bell. Later dynasties and generations are all subject to the Jingyang bell.

"Oh~!"

A chamberlain in the hall hurriedly surrendered his hand to receive the order.

Li Er thought for a while, then looked at Zhao Song again, and ordered, "Zhao Song, you immediately hurry out of the city, go to Lantian County, and invite Yong'an Hou into the palace!" ”

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

Of course, on the other hand, it was Li Zexuan who put forward the prediction of the locust plague last year, and the so-called bell must be tied to the bell, and now that the locust plague is coming as scheduled, of course, Li Zexuan must be invited over to discuss the disaster relief event!

Zhao Song's expression was solemn, and he arched his hand and said, "The old slave obeys the order!" ”

After that, he didn't dare to delay any longer, so he dodged directly and walked out of the hall quickly!

"Bell~! Clang~! Clang~! ”

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

Chongrenfang, the eldest grandson Wuji heard the sound of the bell and drum, and couldn't help but change his complexion, and said, "Someone! Hurry up! The old man wants to enter the palace! ”

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

The eldest grandson Wuji hurriedly explained, "Madam, listen! As soon as the Jingyang bell rang, it means that something big happened in the palace, and the last time the Jingyang bell rang in the afternoon, it was the year before last! ”

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

The noble lady's face changed, and she hurriedly said, "That concubine changes clothes as a master!" ”

The eldest grandson Wuji nodded, he looked up at the locusts in the sky, and said in a low voice, "The locust plague is here, Your Majesty, this should be an urgent recruitment of hundreds of officials into the palace to discuss countermeasures!" ”

………………………………

Above the cloud mountain, the conference room of Yanhuang Academy.

Li Zexuan sat in the first seat, He Xianling, Hu Hanyun, Liu Erye, and Liu Qingfeng sat in the bottom in turn, and it was a little strange that Li Gang, Yan Silu, and Ma Zhou, the gentlemen of Yanhuang Academy, were also present!

Li Zexuan's face sank like water, and after seeing that everyone had arrived, he said in a deep voice, "The locust plague is coming, you must have seen it too, some people regard the locust plague as the wrath of the locust god, what do you think?" ”

Lao Hu stiffened his neck and said, "Young Master, I Lao Hu doesn't read much, but in my life, Lao Hu only respects heaven and earth, not ghosts and gods, what kind of bullshit locust god, it plagues our crops, we should destroy it!" Dissatisfied young master, you said, last year, I Lao Hu also ate a few plates of Feihuang Tengda! ”

Second Master Liu nodded and said, "What Xiao Hu said is right! Young master, the locust plague is very serious now, and the crops in the field can be harvested in a few days, but at this time, there is such a large-scale locust plague, young master, if you have a good way, just say it, as long as you can kill the locusts, I Liu Wanshan will not dare to do it! ”

Liu Qingfeng and He Xianling are both scholars, not as reckless as Liu Erye and Lao Hu, the two of them forced a laugh and said one after another, "Yes!" We all listen to Master Hou! ”

Li Zexuan nodded, and said with a serious face, "Okay!" Ben Hou doesn't believe in any locust gods, even if there is a locust god in this world, then he is also an evil god who poisons living beings, and he can't kill it! The next few things I arranged, you must keep in mind and strictly implement them, because this is a major event related to the life and death of more than 80,000 people in Lantian County! ”
