"This ...... Anyway, the minister just knows that the emperor is right to believe me. Pen, fun, pavilion www. biquge。 info" Zhang Nan said with a grin. Zhang Nan is still very relieved about the system, but even if the system is unreliable, history is always reliable, but the next words of Li Er made Zhang Nan turn from joy to sadness.

"Okay, I believe you, Qingquan, I have decided, when I send troops to the Turks in the Tang Dynasty, you will go out with the army, and it just proves that what you said is true." Li Er also followed Zhang Nan's example and said with a smile.

Before Zhang Nan could react, Cui Shao first jumped out and said: "Think twice about the emperor, Qingquan doesn't know martial arts, what can he do when he goes to the battlefield?" I hope the emperor will think twice. Cui Shao hurriedly said, just kidding, his daughter has just married Zhang Nan, if his son-in-law has something on the battlefield, what can he do with his daughter?

Although Zhang Nan is with the generals in the army even if he goes to the battlefield, but the sword has no eyes on the battlefield, and he is afraid of anything if he is not afraid of 10,000, Cui Shao is still very reluctant to let Zhang Nan go to the battlefield.

"What are you nervous about, don't be afraid, if I Lao Cheng leads the troops to the battle, I will definitely ensure that Qingquan is foolproof." Cheng Yanjin slapped his chest with his big hand.

Cui Shao glanced at Cheng Biting Jin, not knowing what to say.

"Your Majesty, did you really let me go with the army?" Zhang Nan asked cautiously, after all, if you can't go, you won't go, although Zhang Nan likes the army and yearns for the life in the barracks, but if you go to the battlefield, Zhang Nan is still very clear about how many catties and taels he has.

"Naturally it's true, since what you said is so firm, then I don't believe it, and this war against the Turks, I have already thought about sending a hot air balloon to the battlefield to try, if you can't fly on the battlefield, then it's not okay, with you, I will feel much more at ease." Li Er said with a grin. Li Erxin said: "I don't believe that I can't cure you." ”

And Zhang Nan shouted in his heart: "Your Majesty, is it so difficult that in your heart, am I not as valuable as a few hot air balloons?" Of course, Zhang Nan didn't say it, just stood aside with a bitter face, but Li Jing asked first: "Your Majesty, dare to ask what this hot air balloon is, the emperor actually wants to send it to the battlefield." ”

"Oh, this, this is Qingquan's secret weapon for me, I really like it." Li Er said with a smile.

"Your Majesty, tell the ministers to take a look, and the ministers also want to see what this secret weapon is." Cheng Yanjin rubbed his hands and said.

"This ...... It's just so good that you can help me see how effective this hot air balloon is, I think it must be a big killer for the Turks. After Li Er finished speaking, he made a gesture and motioned for everyone to come out with him.

Li Er's gesture, even Fang Xuanling, Du Ruhui, and Sun Wuji, who were discussing the reason for sending troops, were all interested, and they all followed Li Er out, and after a while, everyone came to Li Er's imperial garden.

"Liu Bing, go and ask the guards to prepare, I want to see the results of their recent training." Li Er ordered. After Liu Bing heard this, he was ordered to go down to make arrangements, while Li Er was sitting in the small pavilion in the imperial garden drinking tea, waiting for the hot air balloon to take off.

After waiting for a long time, everyone didn't see what this hot air balloon was, Cheng Yanjin whispered to Wei Chigong beside him: "Heizi, what do you say this hot air balloon is, the emperor actually wants to use it to hit the Turks." ”

"I don't know where to go, but it shouldn't be as powerful as a kamikaze crossbow when it comes to the name. Balloon? The name doesn't sound lethal at all. Wei Chigong pinched his chin and said.

Li Er heard the conversation between the two generals, squinted his eyes and looked at the sky, and found that the hot air balloon had already flown towards this side, and Li Er didn't speak, just to see if these ministers of his own could find out.

As a result, after the hot air balloon circled over everyone's heads three times, everyone still didn't notice the hot air balloon.

"Your Majesty, aren't you kidding my old Cheng, where is this hot air balloon?" Cheng Yanjin and the others were a little impatient, so they asked.

"Zhijie, didn't you see it?" Li Er said with a smile.

"No? Kuroko, do you see that? After hearing this, Wei Chigong also shook his head.

Li Er smiled and said, "Everyone, you haven't found this hot air balloon, which is enough to prove the lethality of this weapon." After Li Er finished speaking, he pointed to the sky with his finger. Everyone looked in the direction of Li Er's finger, but except for Zhang Nan, the rest of the people had grown their mouths.

"Is this the legendary hot air balloon?" Cheng Yanjin looked at the sky with his mouth wide open and said.

"This, how can people go to heaven?" Wei Chigong also said with a shocked face.

Li Er looked at his ministers like a hillbilly, and he forgot what he looked like when he saw the hot air balloon for the first time. Since Zhang Nan provided Li Er with the combustion device of the hot air balloon, Li Er ordered someone to sew a thick animal skin into an airtight airbag, and after breaking the arms and legs of several guards and blowing up two or three gas canisters due to improper operation, Li Er's hot air balloon finally flew up.

"Your Majesty, this hot air balloon is an artifact, look at this height, ordinary bows and arrows can't shoot hot air balloons at all, if we can attack from above, then the Turks don't even have the strength to fight back." Li Jing also said with a look of surprise.

"Yes, that's right, that's what I thought at the time, that's why I asked Qingquan to get me this hot air balloon." Li Er looked like a hero.

"But the emperor, Rong Chen asked, why can't the emperor equip this thing in large quantities? This hot air balloon is not limited by the terrain, and it is not easy to be discovered, if our soldiers of the Tang Dynasty are equipped with a large number of this thing, so that the enemy will not succeed in the battle, and half of them will die first, then the war will be much easier to fight. Li Jing said excitedly.

"Eh, I also want to, how can I send the most important part of the hot air balloon to the sky, we Datang can't make it, and I don't have so much silver to buy." Li Er also looked like he had no choice.

"Oh? That's how it should be. Li Jing continued to ask, it seems that Li Jing is still very satisfied with this new equipment.

Li Er nuanned his mouth and motioned to Li Jing to look at Zhang Nan, Li Jing looked at Zhang Nan who was looking up at the hot air balloon, smiled, as soon as he saw Zhang Nan, Li Jing's heart was already clear, if this thing was provided by Zhang Nan, there was really no way to copy it.

"Okay, ladies and gentlemen, this thing is my secret weapon, and I want to test its actual value, so I want to send him to the battlefield on this expedition." Li Er said with a smile.

At this time, Cheng Yanjin came up and said: "Your Majesty, let's not talk about the rest, just this hot air balloon, can you let my old Cheng also go up and have a good time." ”
