Li Hongbi rushed to prepare.
The military parade also officially began.
Qiu Fu returned to the general station and took several flags from the ordering soldiers.
"Sun Tzu's Art of War: Military Struggle" says: "If you don't hear each other's words, they become golden drums; if you don't see each other, they become flags."
Because of the rudimentary communication methods, flags, drums, golden sounds, horns, and lights were the main communication signals and command methods on ancient battlefields.
The ancient army used flags and drums as a communication and command method to quickly and effectively convey various command orders and liaison signals to the entire army.
However, due to the complex content and numerous clues of the command flag, more time must be spent on teaching and training to make every soldier in the army familiar with this set of command orders.
Therefore, training soldiers to "distinguish flags" and "appraise golden drums" is the first lesson for all soldiers in ancient times after joining the army. "Wu Bei Zhi" says: "Trainers should first understand the distinction between flags and then bind them." That is. This principle.
The more than 30,000 soldiers on the school field are the elite soldiers of the Ming Dynasty's Tiger Army. It goes without saying that basic common sense such as "distinguishing flags" and "appraising golden drums" needs no introduction.
"His Majesty decrees, the review begins!"
In the silence, with Qiu Fu shouting, the review officially kicked off.
Boom, boom, boom!
War drums rumble, military flags hunt!
As the Grand Governor Qiu Fu fiercely waved the order flag in his hand, more than 30,000 soldiers immediately accepted the order, and the array quickly spread out.
In just a few breaths, the original warrior formation was clearly divided into two large arrays, both of which had generals who commanded the changes.
There was not a trace of noise, and there was no one shouting or ordering!
The soldiers all act according to the signal of the order flag. This is the so-called order and prohibition!
Thousands of people formed an army, the armor was tight, and they were as silent as a mountain.
Under the sound of military drums and the command of flags, thousands of soldiers marched forward, retreated, attacked, or defended!
Advance and retreat in a controlled manner, with awe-inspiring order!
As another red flag fell from Qiu Fu's hand, it was the signal to launch an attack.
Originally, the two arrays were still in an offensive and defensive confrontation, but then they quickly changed arrays, with bows and arrows arrayed, and behind the spears and halberds, the war drums suddenly rumbled on the battlefield, and the sky and earth were instantly filled with war clouds and murderous intent!
Then came the battle between the two arrays. Although it was an exercise, it was also very exciting. Both arrays attacked each other and each had their own victory or defeat. The battle situation was actually the same as a real battlefield.
The cold wind is blowing, the war flags are flying, and the sound of drums is still reverberating between heaven and earth. A strong sense of murder has already covered the world.
The whole school grounds instantly turned into a battlefield, and there was a fiery killing scene!
In such a scene, not only Zhu Di and the generals, but also the civil servants and gentry who had always looked down on the warrior Qiu Ba, could not suppress the excitement in their hearts.
The battle formations are lined up, as majestic as a mountain!
Why don't men take Wu Gou and collect the fifty states in Guanshan?
This is what a man should do!
At the same time, inside the dormitory in the corner of the school grounds.
Li Hongbi was looking at the pile of things in front of him with joy.
What was placed in front of him was the standard gunpowder in the Ming army.
The manufacturing method of gunpowder is relatively simple. You only need to pay attention to the proportions of various raw materials and the processing process.
Usually, the three raw materials of saltpeter, charcoal and sulfur are mixed together in a certain proportion, and then ground and sieved to make the particle size uniform and fine. Finally, the mixed gunpowder is put into a gunpowder barrel or other container for use.
In other words, it is often said that "one sulfur, two nitrates, and three charcoals" are used. However, the proportion of Ming Dynasty's standard gunpowder is not right. The proportion of charcoal is too much, resulting in the failure of the three to fully react, and the combustion performance and explosive power are far less than expected result.
Moreover, the various raw materials of this standard gunpowder also have a lot of impurities, which directly affects the power of the gunpowder.
In fact, this kind of gunpowder should be called "black powder", and its power is just that, far from being comparable to the explosives of later generations.
After all, the Nobel Prize-maker and the father of modern explosives blew up his own brother to death and even maimed himself, and then he succeeded in creating a modern explosive with overwhelming destructive power.
Li Hongbi didn't want to mess with such dangerous things and blow himself into a puddle of meat.
What he wants to do now is actually to increase the power of the gunpowder and try to make a simple version of the explosive bag.
In fact, explosive packs had already appeared in the Song Dynasty and were also used in wars.
According to records, the Song army used gunpowder to make a simple explosive package, then added a long fuse, tied it to a bow and arrow and fired it.
In the chaotic battlefield, no one will notice the bows and arrows that can be seen everywhere on the ground. When the fuses burn out the gunpowder, a big explosion will occur in the enemy's formation.
However, due to the crudeness of Song Dynasty gunpowder, which was not as powerful as the Ming Dynasty standard gunpowder, this combat method was not lethal enough, and was limited by the range of bows and arrows. It could only play a certain role at mid-range, so it was quickly abandoned. Got it!
But Li Hongbi knew that bows and arrows were not the only way to launch explosive packets!
And he also knows how to increase the explosive power of black powder!
"Hehe, one sulfur, two carbon, three stone saltpeter, plus sugar!"
Li Hongbi smiled sadly, and then directed a group of soldiers to start purifying.
These soldiers are all Qiu Fu's personal guards and confidants, so they can be completely trusted.
On the school field, Qiu Fu was still waving the flag.
After the two formations of soldiers attacked each other, they began to reorganize their troops and continue to practice martial arts.
There was no other way, he was buying time for Li Hongbi.
Seeing that the martial arts performance is almost over, there is still no news about that bastard boy.
Zhu Di naturally saw Qiu Fu's little thoughts, but he didn't point it out.
To be honest, in Emperor Yongle's heart, he must be looking towards noble military officials such as Qiu Fu and Zhu Neng.
After all, it was these old brothers who fought bloody battles and fought to the death that allowed Zhu Di to successfully enter Jinling and sit on the dragon throne.
As for the civil servants and gentry such as Xie Jin and Yang Rong, it was only to appease the scholars that they were promoted.
Who is close or who is far away, Zhu Di can still carry it clearly.
It wasn't until a personal guard hurried over and nodded to Qiu Fu that the latter breathed a sigh of relief.
Immediately, the troops were ordered to retreat, and the 30,000 soldiers returned to their original positions, just like before.
Zhu Di smiled and said nothing.
But before he could speak, the soldiers of the three armies shouted in unison with a deafening roar.
"Long live your majesty!"
The sky shook with shouts!
With a cry from the crowd, soaring into the sky!
The soldiers are in iron armor, and the military is full of morale!
Zhu Di could no longer suppress the excitement in his heart. He subconsciously stood up on the chariot, his cheeks flushed, as if he was extremely excited.
"Great kindness!"
"I have such a fierce and powerful army, what do the mere northern captives have to fear?"
His Majesty the Emperor laughed and spoke, obviously very satisfied with this review.
However, at this juncture, some people like to seek death.
Xie Jin stroked his beard and said sadly: "Your Majesty, the crown prince of Cao Guogong hasn't come back yet!"
As soon as these words came out, all the generals looked at Jie Jin with unkind expressions, but the latter looked calm and disapproving.
Zhu Di glanced at Xie Jin lightly, but didn't say much.
"Pass on Li Hongbi!"
"Come on, come on!" Li Hongbi walked over slowly, holding a big treasure in his hand.
Qiu Fu knew that this little bastard just wanted something, so he didn't dare to let Li Hongbi take it to the general table.
Damn, that's gunpowder, it will explode if you're not careful!
There are important civil and military ministers on the general stage, and His Majesty the Emperor is here!
If it explodes accidentally, the Yongle Dynasty will be declared destroyed!
This is an accidental injury to His Majesty the Emperor. Every one of these people present will have to be executed!
So Qiu Fu hurried over and took the thing directly from Li Hongbi's hand.
"Brother, don't say I didn't remind you, just run as far away as possible later!"
"By the way, remind my second brother and my father, and leave the others alone. Let them experience the feeling of flying!"
Qiu Fu: "???"
