Li Er glanced at his son with very strange eyes, wondering if he would let his son read less books in the future, and Li Er simply hated Li Chengqian's method of always using money to solve problems.

Datang doesn't have so much money, the money in the treasury looks like a lot, but there is not much if you really need to use it, although Li Chengqian often gets some 'living money', but those money are windfalls, not long-lasting, and emergency can but can't really be counted into daily expenses.

However, Li Chengqian has repeatedly refused to change his teachings, and he has been preaching that 'problems that can be solved with money are not problems.'" This strange argument is true.

I really don't know why I have read so many Confucian theories and worshipped so many famous teachers, how can I learn what I am now, is it true that the brains of geniuses are always different from ordinary people?

Five days passed in a flash, and on the 24th of January, flags were displayed in the military field of the school outside the city, and ten thousand drums were thunderous. Li Er, Fang, Du, Li Jing, Qin Shubao, Cheng Yanjin, Duan Zhixuan and a group of old guys from Tiance Mansion gathered in the stands of the military field of the school.

"Boy, I haven't seen you for a while, I've grown tall!" Cheng Fairy is still the same, and he has not restrained himself a little because Li Chengqian is fifteen years old, he is still a boy, the title of a boy, and the other old guys who listened to it twitched their eyes.

But there is no way, now Cheng Youjing is Li Chengqian's Taishan father-in-law, and it can be said that he is a kid, as long as Li Chengqian does not ascend the throne and become emperor for a day, it is estimated that Cheng Lao will continue to be called like this.

But until now, Li Chengqian is still in the dark, and he doesn't know the specific situation, and he doesn't know that during the time he is not in Chang'an City, the old man has already ordered three family affairs for him, and he is already a man with four wives.

"Uncle Cheng is good." Looking at Lao Cheng's black face, Li Chengqian couldn't help but feel a little stunned, not scared, just simply stunned.

"Let's not talk about anything else, what are those three things below, they look so ugly in the dark, could they be the ...... you made up recently, oh, 'cannon'?" Lao Cheng didn't have the consciousness of being disgusted at all, and stood on the top of the stands and pulled Li Chengqian to nag and ask.

Li Chengqian looked at the old man with a cry for help, but in exchange for a glance of Lao Li asking for more blessings, he had no choice but to bite the bullet Cheng Lao Xiang and continue to pull the skin: "Uncle Cheng, don't be impatient, everything will be known later." ”

"Cheng, then Lao Cheng is watching here, you kid can be careful, don't embarrass Lao Cheng." Cheng Fairy said with a grin, and he didn't look at Li Chengqian's inexplicable eyes.

Damn Cheng Lao, Lao Tzu is a shameful person and a member of the Lao Li family, when can you throw it to your Lao Cheng family, it is really ugly and weird, Li Chengqian, who doesn't know that Lao Cheng is already his father-in-law, secretly complained in his heart.

"Prince, is everything ready?" Chang'an in the first month is still a little cold, the little tail of winter has not completely passed, Li Er sat on the high platform, and felt a little unbearable against the cold wind.

This is the reason why he has been confined to the palace for many years and has not exercised much, if it is placed in that year, even if it is a cold winter, he will not feel cold with his bare shoulders. Of course, this is what Li Er himself thinks, looking back on the past, Li Er, who is in his thirties, already has a feeling of 'urinating against the wind back then, and now he has wet shoes in the wind'.

"Father, it's ready, ready to start." After Li Chengqian asked a question from under the stands, he turned back to Li Er and said.

"Get ready and go." Li Er waved his hand impatiently.

"Whoa!" After Li Chengqian agreed, he made a few gestures to a few 'fangs' elites standing under the stands, and then retracted back to the top of the stands, and Li Er's side attracted everyone's curious attention.

"Boy, what the hell are you doing? Didn't you always be in front of you before? And what are you doing like an iron bucket? Cheng Lao looked down, then looked at Li Chengqian, and said disdainfully.

Li Chengqian turned a blind eye to Cheng Lao's contempt, and just said to himself: "That thing below is very dangerous, and the little nephew suggests that it is better for the uncles to retreat a little farther." ”

Li Chengqian didn't say that it was dangerous, but as soon as he talked about danger, Lao Cheng took a few steps forward, stood by the stands to look, and turned around and said, "Danger? How dangerous can it be? Lao Cheng has never seen any danger in his life. ”

Looking at the 'cannon' below, which was about 100 steps away from the stands, Li Chengqian estimated the degree of danger, and felt that even if it was blown up, it would not be able to fly to the stands, so he didn't care much about Lao Cheng's competitiveness, but just turned his head and said to the old man: "Father, it's about to start, it may be a little loud for a while, you pay attention." ”

"Let your people get started quickly." Li Er nodded and said that he already knew.

"It's already started." Li Chengqian watched as the sergeant below lit the fuse of the earthen cannon, and fled like a fly, automatically and consciously blocking his ears.

"Boom Boom"

Three loud bangs sounded almost at the same time, and the stands were still shaking wildly after more than a hundred steps, and some of the old ashes were shaken out.

The old guys in the stands who didn't care, laughed and joked with each other were shocked and almost jumped, of course, maybe they were scared.

The Nine Days of Thunder is no longer enough to describe these three loud noises, who has ever seen such a loud sound in ancient times except for thunder? They had heard about it when they had tested gunpowder the last time, but they had forgotten it for so long now.

And Li Er only said that he was testing guns this time, not trying gunpowder!

Although Li Er was prepared in his heart, he was still a little stunned, looking at the gun position filled with gunpowder a hundred steps away, he didn't know what to say for a while.

"Father! Father! Li Chengqian called out to Li Eryi several times, called the old man's soul back, and then said: "Father, I've already tried it, let's go and see how the effect is?" ”

"See the effect? Boy, you're not trying to scare your enemies to death, are you? Cheng Yanjin patted his ears, turned his head from the front of the stands, and said to Li Chengqian.

Because of the distance, although the sound of the cannon was a little loud, it did not cause any damage to everyone's ears, and there was no problem with normal communication.

Li Chengqian is not a fool, even if it is not for those old goods, he has to think for himself, he doesn't want to become a deaf person at a young age. Besides, if the old man is deaf, it is estimated that he will not be able to save his two legs.

"Uncle Cheng, don't say whether you are scared or not, the war horse has been brought over, let's go and see the results?" Li Chengqian was too lazy to have a verbal dispute with Cheng Lao, and after consulting the old man's opinion, he invited the old goods of Tiance Mansion who had recovered slightly.
