"For the Tang Army?" Li Shimin was stunned for a moment, then his face turned dark, and he was about to change his face: "I see that you don't cry when you don't see the coffin, and you won't tell the truth if you don't draw this cane on your body, right?!" ”

"Ouch, Your Majesty, you have wronged Weichen. www.biquge.info"Xia Hongsheng pretended to be stupid, as the saying goes, confess leniently, sit in prison, resist strictly, and go home for the New Year." Xia Hongsheng decided to continue to fool Li Shimin: "Your Majesty, this thing is really made by Weichen for our Tang Army." Please let Your Majesty allow Weichen to explain one or two to Your Majesty. ”

Li Shimin stared at Xia Hongsheng and glared, with a vicious look, and said, "Speak!" ”

"Yes!" Xia Hongsheng said to Li Shimin: "Your Majesty, aren't our Tang Dynasty preparing to recover Liaodong and conquer Goguryeo?" However, Goguryeo is poor and has bad waters, and it is not a nomadic people, and it is still learning from our Tang Dynasty to build cities. It is said that the construction of its national capital is no less than our Chang'an. Goguryeo has a geographical advantage! There are many mountains and rivers there, and our soldiers are not familiar with the place where they go, but the Goguryeo people are very familiar with it. They could have ambushed us in the mountains. How can we make the Goguryeo army hidden in the mountains and forests and huddled in the city have no secrets in front of our Tang Dynasty soldiers and can be seen at a glance? In order to solve this problem, Weichen made such a thing. ”

Li Shimin was stunned for a moment, then his eyes froze, and he said: "You mean, use this thing to let my Tang soldiers fly to the sky to attack Goguryeo?" ”

"No, Your Majesty, there are so many soldiers in the Tang Dynasty, how can this hot air balloon fit it?" Xia Hongsheng shook his head and said to Li Shimin: "Your Majesty, as the saying goes, climbing high and looking far away is like being in Jingyang, as long as you go up to the last mountain of the academy, you can see the entire Jingyang at a glance. This hot air balloon made by Weichen can fly into the sky, if our Datang Tanma flies to the sky with this thing, and then cooperates with the telescope, then how many enemy soldiers are there, where are they ambushed, how are the camp tents arranged, and how many defenders are there in the city...... Wouldn't it be all in sight? In this way, our Datang army will be able to anticipate the enemy's opportunity, and the enemy's actions are all in our eyes. ”

"I understand." Li Shimin squinted his eyes and showed a very evil-looking smile, and said, "I want the soldiers of the Tang Dynasty to fly to the sky to attack Goguryeo!" ”

Xia Hongsheng was stunned, and immediately understood what Li Shimin meant.

"Your Majesty, no!" Xia Hongsheng said to Li Shimin: "Your Majesty, although this hot air balloon can fly to the sky with people, it also has very inconvenient places. First of all, because it relies on the heat to rise and drive the hot air balloon to the sky, so in order to make it rise smoothly, the things carried below should not be too heavy, and the people who can carry it to the sky will only be three or four people who will die. In addition, the hot air balloon depends on the direction of the wind, and wherever the wind blows, the hot air balloon will float in the direction, not human control. These two points alone limit the role of the hot air balloon, which can only be used as a support, not as a primary offensive weapon. It can't carry so many people, let alone many weapons. ”

Li Shimin smiled, waved his hand, and said, "Xia Qing, listen to me." When I look at its flight to the sky today, I know that it is driven by the wind. However, Xia Qing thought that today you flew in Chang'an, and the people of Chang'an didn't know what it was, and they were all frightened. If it weren't for those notes, I was afraid that it would have scared many people. How could this not be used to attack Goguryeo? It's just that the note of Tang Wansheng was replaced with a note of Goguryeo's defeat. When they see it, they will be greatly frightened, and if they throw paper at it, their people will be suspicious and leave the court. The people are not distracted, and the soldiers have no morale, how can they still be the opponents of my Tang Dynasty soldiers? Furthermore, this thing cannot be loaded, and I do not need to carry it. One person, several firearms are enough. Hehe......"

Xia Hongsheng was stunned for a moment, and suddenly thought of Li Shimin's intention: "What does Your Majesty mean...... Surprise! ”

"Hehe, that's good!" Li Shimin stroked his palms and smiled, and said to Xia Hongsheng: "This thing is in the sky, it is already appalling. If you suddenly appear in front of the enemy, you will definitely make you nervous and panicked. At this moment, if the people above ignite the firearms and throw them from the sky into the enemy's ranks, camps, or cities, it will inevitably cause panic. At this moment, the army followed, and the enemy army was defeated and could no longer resist. Xia Qing, how high can this thing fly, and can it be shot out of the steel crossbow? ”

"If a fire flies, this thing will fly about sixty or seventy feet high during the first test flight." Xia Hongsheng thought for a while and said, "Now the effective range of the steel crossbow equipped by our Datang is about sixty zhang, and it stands to reason that it can avoid the steel crossbow shot from below. ”

"Good!" Li Shimin nodded, smiled very slyly, and said: "Hehe, seeing that this thing is beneficial to my Tang Army, and it has enhanced the prestige of the imperial court in the hearts of the people, I will not pursue your breaking into the harem and the princess's bedroom today." Hmph, if you kid can be so attentive to the affairs of the court and state, you will definitely be able to make a difference. It's a pity, huh! No ambitions! ”

Li Shimin taught Xia Hongsheng a second lesson, and then paced away with satisfaction and comfort, and went to the front to play drunk and crazy with those drunk courtiers.

Xia Hongsheng glanced at Li Shimin's back, Damn, this son has no ambitions? Lame!

After making a few grimaces at Li Shimin's back, Xia Hongsheng hurriedly sneaked out of the Taiji Hall and ran to the back.

My son doesn't know you Li Er, and my son is going on a date! Wowha! ……

Under the bright moonlight, Xia Hongsheng trotted and ran to the garden closest to the Taiji Palace.

In the gazebo, under the moonlight, a gentle figure was standing there, waiting.

Xia Hongsheng's heart warmed, and he walked over quickly.

"Princess......" Xia Hongsheng stepped forward and called.

"Childe!" Li Lizhen turned around happily.

"Ahem......" There were a few coughing sounds next to him: "I'm still here." ”

Xia Hongsheng immediately heard this voice, grabbed him in the past, and said angrily: "Okay, you Li Ke, I didn't look for you, you still dare to stay here and wait for death?" My son asked you to come and deliver the message, but you are so good, you dare to betray me! ”

"Ouch! Brother Sheng! Li Ke hurriedly flattered: "It's not that Ke betrayed his brother and betrayed his teacher, but it was really my father's coercion that was too great...... Brother Sheng'er spares his life, Brother Sheng'er spares his life! ”

Xia Hongsheng let go of Li Ke, cut, for the sake of your sincerity, spare you.

As soon as Li Ke was released, the excitement immediately came up again, and he asked Xia Hongsheng very excitedly: "I said Brother Sheng, you have been making up the formation in the academy for so long just to round my sister's words?!" (To be continued.) )
