The two of you are incompatible with each other, and it took a while to cool down, Li Shimin took a sip of the teacup and said;

"Tell me what's going on with that flying ball of yours."

Li Shen is also tired, this day is really sad.

"It's a flying ball," replied Li Shen.

"Bastard, I didn't know it was a flying ball, I asked how you got it." Li Shimin was angry.

"Oh, I don't know how to get it out, it's all made out of that laboratory in Dongshan, and it's enlarged according to the style of Kong Ming lantern." Li Shen explained.

"Why didn't you take out such a weapon earlier?"

"Aye, the technology of this hot air balloon is not mature, it is not flying high enough, it is not fast enough, and the time to fly is short,

The lab is now improving the material burned. ”

"Can it be mass-produced, this will have a great effect on my Datang military." Li Shimin thought of the military role, and Li Shen thought of fleeing for his life.

"Aye, this can be mass-produced after it is improved, but the technology of this thing is actually not that complicated, and I am afraid that it will be used by some people.

It's better to have this thing in your own hands. No, then there will be endless troubles. ”

Although Li Shen did not know anything about military affairs, he also knew air supremacy, and there was no solution to air supremacy in this era.

If the gangsters know the technology, let alone attack the city, they can't stand it even if they fly over the palace and throw fire bombs.

The hot air balloon that Li Shen has made so far can fly up to seven or eight hundred meters.

If it's a fuel change, it's sustainable, and it's not a problem for thousands of meters, and this is not within range at all.

Of course, Li Shimin understood what Li Shen meant, and now Datang is not without enemies, and in fact, the interior is not very calm.

"Then what can you do, this hot air balloon is very important to Datang's military, whether it is offensive or defensive, it will be a sharp weapon." Li Shimin asked Li Shen.

"There is nothing we can do but resist with the same hot air balloon, if the technology spreads, then we can only send people to raise the hot air balloon every day, and monitor it in the air at all times. Equip our crossbow and take out the enemy before they come. ”

Without ground-to-air weapons, Li Shen can think of this is the only way he can think of at present.

Li Shimin pondered for a while and then said,

"You send two planes to the Beiya Forbidden Army, and the rest will be said after you improve it, all those who know the production method must be strictly guarded, write a copy of the production method and send it to the palace, and I will keep it personally."

Li Shimin said in the end that Li Shen was not disgusted, this is very normal, such a sharp weapon will definitely not let you have it personally,

If this is developed by ordinary people, it will either be made by the state under house arrest for life, or it will be handed over and finally killed and killed.

Fortunately, Li Shen is a rich prince.

Li Shen nodded, this ending is already very good, he actually has a lot of contraband in his hands, such as gunpowder, this is Pandora's box,

Over the years, he had experimented with the best recipes and was still refining them, but nothing came out of it, only flares.

He was afraid that after handing it over early, this thing would be spread out, and then the world would be in chaos.

After a while, Empress Sun came again, and when she heard that the two of them were arguing, she asked them to come out to eat.

The two of them drank the wine brought by Li Shen and chatted about the current situation of Goguryeo, Li Shimin did not expect that the current situation of Goguryeo was even worse than what was written in the intelligence.

"The food problem should be no problem at the moment, and the first batch of rice you brought back has already started to be harvested. Some areas of Lingnan can be triple cropped.

In most areas, there is still a double crop, but this is already good, and the harvest of the double crop will start immediately. ”

Hearing Li Shen say that Goguryeo was short of food, Li Shimin spoke.

"That's great, if that's the case, it will be of great help to us in capturing Goguryeo, and whoever the people give food will follow." Li Shen said happily.

"Well, your Huairou policy is very good, give the people a reason to follow me Li Tang, and let the people know the benefits of following our Datang." Li Shimin also agrees with Li Shen's approach.

"Aye, I received an intelligence family that seems to want to give Goguryeo food, and I heard that the Xiao family helped to check it."

For the family, Li Shen has the opportunity to take revenge.

"I also received the news that they were transporting grain under the pretext of porcelain, but they were already on board when I knew about it, and I found out that they sent three warships to escort them."

Li Shimin is the second generation of the founding emperor, and there are many talents in his hands, and the information is naturally the same, but sometimes the family wants to hide it, and it is just a little late.

"Three warships, the Xiao family is really generous, they are not afraid of things being exposed?" Li Shen was surprised.

"When the Xiao family smuggles to the north and northwest, the family will also help, they are mutually beneficial." Li Shimin explained.

It seems that Li Shimin knows these things, but sometimes there is no way.

"They're such a huge interest group." Li Shen has a headache, he has been tossing for more than ten years, the family has only weakened a little, the money is a little less, and the power is a little less.

Nothing else has changed at all, this is still a situation where the family has no way to take him, if he is killed by the family, it is conceivable that the family will recover soon.

It's just that Li Shimin doesn't think so, and now the family's power in the court is getting smaller and smaller, especially some of the state and county officials below, because there are more scholars, many people have been arranged to be small officials.

Now the Ministry of Officials is the focus of Li Shimin's attention, and whoever dares to play a conspiracy Li Shimin will get it for you.

"I also heard that your caravan was attacked in the north, with heavy casualties, do you know who did it?" Suddenly Li Shimin asked this question,

While he was picking up vegetables, he looked at Li Shen's expression,

Li Shen didn't notice that Li Shimin was observing him, but shook his head,

"There is no news at the moment, so the north has stopped caravan activities now, and we will talk about it when it is found out." Li Shen replied.

"Oh." Li Shimin nodded, regained his expression, smiled and took a sip of wine, and then said;

"I think the family is the most suspicious, but they have suffered several losses from you, you can start from this aspect."

Li Shen nodded, he thought so at first, but he felt that something was wrong,

"At present, it is like this, either it is a family or Xue Yantuo. I'll talk about it when I find out. ”

Seeing this, Li Shimin didn't say much, but began to talk about something else.

This meal lasted for more than an hour, mainly Li Shimin and Li Shen, the eldest grandson, Empress Wei Guifei, the crown princess, and Li Shen's wife were all accompanied.

In the end, the eldest grandson queen couldn't stand the chatter of the two of them, and pulled everyone to chat.

Li Shen returned to the palace drunk and slept until the afternoon, when Li Shen's three housekeepers had been waiting for a long time.
