"Everyone has seen that this is a flat river, and it is the favorite of the cavalry. They can increase the speed of their horses to the highest level without restriction and slaughter the infantry. Li Dongsheng talked eloquently: "But my Datang has the latest weapons, today I will show you the most real battle process of my Datang, please keep your eyes open and cover your ears, so as not to be frightened." ”

Everyone scoffed at Li Dongsheng's words, with the latest weapon, that is, grenades, everyone has seen it, it made a huge noise, and then caused a certain amount of damage, and the Tang army pressed in again, so the cavalry collapsed. Now everyone knows the routines of the Tang Army, and everyone is brainstorming, and when they fight with the Tang Army again, everyone will block the ears of the war horses, and the war horses will not be afraid if they can't hear the sound, as long as the formation is not chaotic, then they are not afraid of any new weapons of the Tang Army.

Looking at the confident looks of the Tibetans and the Turks, Li Dongsheng said in his heart If the weapon that Lao Tzu wants to engage in is guessed by you, it will really not be mixed.

Those horses sitting on dummies rumbled across the viewing platform, and when they continued to run forward, the overwhelming momentum was really a little scary, Li Shimin and the ministers of the Tang Dynasty looked solemn, at this time, they heard a loud "boom", and the entire viewing platform was shaken, and then there were a series of explosions, the huge sound and smoke stunned everyone present, and the envoys of Tibet and the Turks were stunned: What kind of weapon is this? Can't see anyone coming out to throw, just exploding out of thin air? This is too much, just figured out a way to deal with grenades, you took out another one, how can we come to Datang to rob happily in the future?

After the explosion stopped, the wind blew away the smoke, and what was displayed in front of everyone's eyes was a hellish look, where were only a few hundred of the thousands of horses left just now, and the ground was full of big pits, huge, and then there were horses lying on the ground screaming, broken legs and heads, and their stomachs were blown through,,,, everyone gasped: "When did the explosion become so powerful?" ”

Li Shimin said excitedly: "Li Dongsheng, what kind of weapon is this?" ”

"Back to Your Majesty, this weapon is called a landmine. It is to bury this weapon in the ground in advance, and if a person or horse walks up to it, it will explode. And it's amazingly powerful, it's the latest weapon. "Today's theme is to scare them into these dirt buns, so Li Dongsheng explained very carefully.

"You mean just bury it and leave it alone?"

"Yes, Your Majesty, as long as this is buried in a pre-planned place, as soon as the enemy enters this place, they are doomed." Li Dongsheng said proudly.

"Alright, alright, what's new?" Li Shimin was very satisfied with Li Dongsheng's precedence, and he was in a good mood when he saw the awe on the faces of those envoys.

"Ladies and gentlemen, the cavalry that was demonstrated just now entered the minefield array planted by our Tang army and received the first wave of blows, and then our army continued to attack, please look up...

Everyone looked up and exclaimed, "What's that?" ”

Li Dongsheng said: "This is called a hot air balloon, and it is also my Datang's latest weapon. None of the envoys of those small countries have ever seen anything that can fly in the sky, some of them knelt and kowtowed, and some people ran to Li Shimin and kowtowed: "Your Majesty is the Khan of the Heavens, and there are weapons that can only be used by gods, and we swear to always follow in your footsteps and never betray in our lives." ”

Li Shimin also stared at this hot air balloon for a long time, and did not understand the main working principle, the hot air balloons floated over very quickly, and when they arrived at the place of the explosion just now, they saw that there was something black thrown down, only to hear the sound of the teacup being broken, Li Dongsheng explained: "This lost weapon is called an incendiary bomb, just a little bit... ”

As soon as he was halfway through his words, he saw a few torches dropped on the hot air balloon, and then with a "coax", the entire battlefield burned. Under normal circumstances, the fire is slowly rising, this fire is different, as soon as it burns up, it is a fireball that rises in the air, and then the flames are higher than people, those injured and not dead war horses are burned by the fire and let out a terrible scream, and the war horses that were not killed are also frightened to run around, and then detonate the mine that did not explode just now, and the explosion was heard, and the horse's screams became one.

Li Shimin watched it with relish, these were all tricks for the Tang army to kill the enemy in the future, and how good it would be to destroy the enemy without casualties or with few casualties.

The two envoys of the Tibetans and the Turks looked as ugly as if they had eaten a feces, and they had already seen that this exercise was aimed at them, and asked them to pass the news back and let their own people say how powerful the weapons of the Tang army were, which showed that the Tang army had absolute confidence in defusing the attack of the Tibetans and the Turks.

"After the second wave of attacks, the attacking cavalry encountered strong resistance, and our Tang army only began to appear after they suffered heavy losses."

At this time, there was another black line in the distance in the sky, no, it should be a silver line, and the cavalry of the Tang Army was all over the mountains, and after forming an offensive formation, they slowly leaned over.

Li Shimin, like those envoys, was curious to see why their armor turned silver. When they got closer, the Tibetans and the Turks gasped, looked at the cavalry covered in plate armor with envy and hatred, and scolded in their hearts: "What a sin, we don't have a piece of iron on the plateau to make a pot, and now the Tang Dynasty is so extravagant that it makes these cavalry fully armoured, how much fine iron does this cost." ”

At this time, there were not many horses standing, and these cavalry went into battle to collect the corpses, everyone looked at the horse corpses on the ground, and then looked at the Tang Army who was armed to the teeth with strong soldiers and horses, and sighed in their hearts: It is really stressful to be neighbors with such a powerful person.

Li Shimin knew that today's exercise was about to mature, and that he had already achieved the goal of knocking on the mountain and shaking the tiger. No one can say exactly how things will develop later, so we will solve the matter in front of us first.

A month after the exercise, Li Shimin's edict to personally conquer Goguryeo came down, anyway, it means the same thing, you Goguryeo is too arrogant, I can't get used to it, and now I'm going to cut you.

As soon as the will of this side was issued, Chang'an City entered a state of combat readiness.

The 100,000 soldiers and horses of the right camp outside the city have been assembled, and the officials of the household department have allocated grain and grass overnight. In this expedition, Li Shimin wanted to settle Goguryeo in a battle, he not only mobilized the 100,000 troops of the camps left and right in the capital, but also mobilized more than 100,000 troops from the Jiang, Xia, Huai, Ling and other prefectures, in addition to the border troops of Yingzhou and Songmo Prefecture, Pinglu and Lulong Town's local regiments and armed forces, and even including Turkic, Qiang, Xianbei and other foreign soldiers, with a total of 300,000 troops in each prefecture, which can be described as the strength of the country.
