In the end, after some careful consideration, Zhang Nan decided not to go to Taiyuan, because it was really a bit dangerous, after all, Zhang Nan now has to think about himself, although he still looks like a behemoth in the family first, and it is still untouchable, but Zhang Nan believes that with a perfect education system, the end of the family is only a matter of time.

Zhang Nan still decided to let him go with the flow, after all, time is the real answer, this kind of family that can affect the court will eventually die with the end of the imperial system, which is the inevitability of history.

So Zhang Nan is not willing to lead the direction of history by himself, after all, it is better to let it develop slowly according to time, Zhang Nan never thought that the Tang Dynasty would be for generations.

However, what Zhang Nan didn't expect was that when Comrade Li Er went to court the next day, he selectively ignored this matter, as if it had never happened.

This made Zhang Nan feel very surprised, after all, Comrade Li Er looked like he was about to send out his thunderous anger, where did he think that it was the result of heavy thunder and small rain?

However, seeing that several of Comrade Li Er's henchmen were accustomed to it, Zhang Nan also decided not to get involved in this matter anymore. And Comrade Li Er didn't mention the matter of letting Zhang Nan do Taiyuan Taishou again, and Zhang Nan was also happy to be idle.

In the next few days, Zhang Nan still stayed in the Tiangong Department, but the Tiangong Department gave Zhang Nan a small surprise.

That is, the Ministry of Heavenly Engineering successfully created a thermal weapon, and also skipped the simplest musket, and jumped directly on top of the firecracker, which Zhang Nan did not expect at all.

After all, the last time Zhang Nan went to the Tiangong Department, the Tiangong Department didn't even make a firecracker, and this time he took out a delicately made hairpistol, which was something that Zhang Nan never expected.

After Zhang Nan learned the news, Zhang Nan entered the palace as soon as possible.

"Your Majesty, the Ministry of Heavenly Works has a good thing, I wonder if the emperor is interested in taking a look?" Zhang Nan said to Comrade Li Er with a mysterious face.

At this time, Comrade Li Er was in the Imperial Garden with Empress Changsun to enjoy the flowers, and when he heard Zhang Nan say this, Comrade Li Er didn't even look back and asked: "What, what has the Ministry of Heavenly Engineering made that can make you a good thing." ”

"Good things are good things, if the emperor is not interested, forget it, but the minister can tell the emperor, with this thing, basically our army in the Tang Dynasty can reduce half of its strength and still achieve combat effectiveness, your Majesty, you can do it." After Zhang Nan finished speaking, he stood aside and didn't speak.

Zhang Nan knew that Li Er would definitely be tempted when he heard this result, because now in addition to Datang's infrastructure, Datang's army can be said to be the second largest expenditure, and even compared with Datang's infrastructure, it is on par with Datang's infrastructure, which can give Comrade Li Er a headache.

As a general of the three armies, Comrade Li Er naturally hoped that the more troops he had, the better, but as an emperor, Comrade Li Er had a headache for this huge army.

Nothing else, just the word "money".

Datang's military expenses are basically drawn from the treasury, when recruiting soldiers in the past, Li Er always had a headache that this soldier could not be recruited, but now it is different, through the reform of the military system, soldiers are no longer a thankless existence, but have become a respectable profession.

This makes many young people of school-age who have not studied excited, not to mention that there is a military academy brand that supports it, and it also attracts many young people who want to make contributions.

Therefore, the current Datang can be said to have a surplus of soldiers, and even slowed down the economic development of Datang. But Li Er didn't dare to send these people back, after all, these are all real combat effectiveness, and they are all existences that can take up arms to defend the country, and Li Er is not willing to let go easily.

Now that Zhang Nan suddenly said that the Ministry of Heavenly Engineering has come up with something that can cut the general number of troops and maintain the same combat effectiveness, how can Comrade Li Er not be tempted?

Sure enough, after listening to Zhang Nan's words, not only Comrade Li Er, but even Empress Changsun showed a look of surprise.

"Qingquan, this is a bit big, right, can you still maintain your combat effectiveness with half of your troops?" Empress Eldest Sun obviously didn't believe that Zhang Nan would say such unbelievable words with this mouth.

"The queen mother, this is only what you can't think of, there is nothing that can't be done, before the hot air balloon comes out, don't you also believe that it is impossible for people to fly?" Zhang Nan said with a smile.

"Okay, don't sell it here, you can just say what the Ministry of Heavenly Engineering has created." Li Er waved his hand and signaled Zhang Nan not to beep more, just go straight to the dry goods.

Zhang Nan said with a smile: "Your Majesty, as the so-called good meal is not afraid of being late, the minister will ask you first, do you remember the thing that the minister gave to Kim Shengman when we were in Silla?" ”

"Aren't you talking nonsense?" Li Er glanced at Zhang Nan and said. How could Li Er forget about this Desert Eagle? Comrade Li Er had been thinking about this desert eagle for a long time at first, but because of the problem of time and the war, Comrade Li Er finally let Zhang Nan go and did not continue to ask more.

But this thing that can kill people in a few steps is something that Li Er likes very much.

Zhang Nan was bored with himself, and he was not discouraged, but continued: "Did the emperor ever think that our Ministry of Heavenly Works would also be able to create this thing. ”

After listening to Zhang Nan's words, Li Eryan stood up from the stone bench in the imperial garden, and then walked quickly to Zhang Nan's side, shook Zhang Nan's arm with both hands and said, "Qingquan, what you said is true?" ”

Zhang Nan was stunned by Li Erhuang, but still said: "That's natural, although that thing is not as advanced as the minister took out, but it's almost the same, is the emperor interested in going to see it?" ”

"So what are you waiting for? Hurry up. Li Er urged.

"Well, let's go now?" Zhang Nan said.

"Let's go, Liu Bing, hurry up and prepare a horse for me, no, don't prepare a horse, drive the car over, I will take the car directly." Li Er also said impatiently.

There is no big deal on weekdays, Comrade Li Er will not move his own car, after all, that thing burns gasoline, and this gasoline is only available to Zhang Nan, although Li Er asked Zhang Nan to ask for it, Zhang Nan could not give it.

But Li Er couldn't wipe his face and asked Zhang Nan every time, so when it was not a major event, Comrade Li Er would not take a car.
