Li Shimin still appreciates the prince's willingness to directly hand over the gunpowder weapon. Although it was nothing for him to keep in his hands, handing it over showed that he was still very relieved about his father and didn't think about leaving any hole cards for himself. That's good! There are some things he can do himself, but he never wants his children to do the same.

Speaking of gunpowder weapons, it is not something that can be explained in a while.

The emperor's guards completely emptied the surroundings, and there was no one nearby except the father and son, so there was no need to be particularly vigilant.

Starting from the composition of gunpowder, it is actually very simple, sulfur is flammable, charcoal is also combustible, saltpeter is the focus, because it supports combustion, shortens the long burning time to an instant, and the heat and gas generated in an instant are its initial lethality. The fragment damage of grenades and arrows is nothing more than a product of it.

Li Shimin is not a stupid person, and after Li Chengqian's explanation, he also understands what gunpowder is all about.

"It used to be just a thing that produced smoke, but after it was changed, it has such power, and I still underestimate the little things in life. If it weren't for you, it would be hard to imagine that gunpowder was made up of these three simple things. ”

The time of conversation always passed quickly, and the fish did not catch a single one, but the time was noon.

The eldest grandson personally came over with a food box, not to show that he was virtuous, but because no one dared to approach the embankment at present. The emperor rarely used such words as "kill him", but now that he uses it, it can only show that his conversation with the crown prince is really top secret.

"Gunpowder weapons still have their limitations in the end, and a battle like melee is simply useless, and who knows if a grenade will hurt its own allies? Therefore, the best way to show the power of gunpowder weapons is to siege and defend the city, because no matter what, the enemy will not scatter the battle line. And when facing a direct battle, before the distance is closer, can you still use gunpowder weapons? But after getting completely close? still has to rely on real knives and real guns to decide the winner. Because of this, the training of our Datang army? I still can't relax. Does anyone really think that gunpowder weapons can completely replace personal force? This man's brain must have been licked by a dog. ”

Seeing that Li Chengqian's mouth was drooling, the eldest grandson smiled and slapped him on the head: "Your father and son? Can you also talk and forget the time, eat first? It's not too late to talk about this after eating. ”

Open the food box? The eldest grandson took out four dishes and one soup, as well as two large bowls of rice.

These are all things in the academy cafeteria, and the emperor's palace is simply exempt from kitchen facilities because of its proximity to the academy? Just stay here? will go to the academy to eat directly. Of course, there is a cost. After all, the emperor and empress can eat for nothing, and the academy doesn't plan to count all those guards and the like into the ranks of the uncle.

Since Li Chengqian decided to withdraw his investment, the food in the college canteen has regressed a lot? Meat has changed from a full meal every three days to a meal every five days, which is still limited. There were still people complaining? But when they heard the reason, they all kept their mouths shut. This? Let Yang Du be very pleased to be able to let the students learn to share weal and woe? Finding a sense of belonging to the College? He doesn't get tired of eating wild vegetables.

There are too many bigwigs visiting today? The academy can only open meat temporarily. As long as the academy is still in the world, such face-saving work is indispensable.

Braised pork ribs never get tired of eating crooked one day, and Li Chengqian feels that he prefers the feeling of completely removing the meat from the bone rather than the taste of the pork ribs.

In front of the eldest grandson, Li Chengqian had nothing to avoid, and said while eating: "Father, the local Zhechong Mansion asked the imperial court to formulate a training charter, and the son-in-law asked Duke Wei to fold the training intensity in half and send it down, what do you think?" ”

"Training, this still has to be taken seriously. As you said, the bravery of a soldier can never be replaced by a weapon. I have now concentrated military power, downplaying the influence of generals on a given army and weakening their right to speak. The concentration of military power to this extent, and not a single person has complained, which shows that they are still very respectful. Perhaps, since they have nothing to do in Chang'an now, then allow them to patrol the armaments of various places as patrol envoys in batches. Originally, this was all the work of civil officials and imperial historians, and it was nothing to hand it over to them. ”

Li Chengqian nodded, except for Wei Chigong and Cheng Yanjin, who were taken out by the emperor for a round because they were lucky, the rest of the generals except for a few who were guarding outside and staying behind, they were all staying in Chang'an as otaku. If you don't find something to do for them, someone will always go crazy.

After eating, the eldest grandson packed up all the dishes and left the space for the father and son to talk.

"Let's talk about Tibet, I can't make up my mind about the affairs of the vassal country. Let it go, Tubo will have a large area of contact with our Datang, and there will be no buffer ground, but if you manage too much, it will also attract the disgust of Tubo. One day, if Datang wants to attack Tuyuhun and other places, he must always get the support of Tubo. ”

Listening to the words of the emperor's father, Li Chengqian immediately smiled. The so-called exchanges between countries will not have any relationship between countries, and such a ridiculous argument as good or bad has always been the importance of interests. Datang doesn't need to gain the favor of Tubo, the real purpose is actually to beat others, and he doesn't want Tubo to interfere.

"Father thinks Tuguhun must be recruited?"

"Must be recruited, not to mention that it is the most restless one in the Tang West, that is, the national strength, and it is not very strong. As long as the forces in the west are drawn and divided, and the Eastern Turkic lineup is not needed, it is enough to take it down. Gaochang is the throat to the Western Regions, do you think Tuyuhun is not? Your gunpowder weapons are good enough to shock the world, as long as it has an effect, I will send troops to Gaochang next year, although it is not too late for a gentleman to take revenge for ten years, but Lu Wentai is so indistinguishable from the situation that I am really annoyed enough! ”

Looking at the direction of the northwest, Li Chengqian was convinced: "The pro-rate rate will not disappoint me, let alone outsiders, even the people inside our Datang always feel that two thousand people are nothing great." However, they didn't know that after being trained by Erchen and Wei Gong many times, and then taking gunpowder weapons, their combat effectiveness would not only increase fivefold! ”

When it came to the pro-rate, Li Shimin said with a smile: "I knew that you would be negligent, so when I was in Qizhou, I sent an urgent letter to Zhang Jian, asking him to dispatch and respond to the pro-rate." Boy, it's a good thing to have confidence in your own manpower, but there is a specialization in the art industry, Zhang Jian has been in Liaodong for many years, and he is the most familiar with Goryeo in the Manchu Dynasty. Without his help, how could he cross the border of Goryeo? ”

Li Chengqian scratched his head and said: "Erchen didn't think about it, he just wanted to let Qin lead a lesson to the Koreans with gunpowder weapons, so that they didn't dare to go out." With a gunpowder force of 2,000 people, it was no problem to fight more than 10,000 Koreans at the door. If the dogs jumped over the wall in a hurry, they would just run. Retreating in front of 100,000 people, no one can say anything. ”

Li Shimin smiled bitterly: "Why is it still a child's temper when you are thirteen, since you want to be powerful, you can't just go through the motions, beat the hyena of Goryeo, only Li Liao's fur is harmless, chopping off one of its claws is the best way." Forget it, Zhang Jian should be able to lead the pro-rate rate to meet my expectations. You don't want to meddle too much. ”

Li Chengqian could only nod his head and agree, in the military, listening to the emperor's father, there is a high probability that there will be no mistakes.

After waiting for a morning, the fishing line finally moved, and Li Shimin struggled to retract the fishing line, but when he saw that it was a carp that bit the bait, he immediately exclaimed.

"Father still thinks it's bad to eat carp?"

Throwing the carp into the fish basket, Li Shimin said indifferently: "No, it's been taboo for a while, and it can't be changed for a while." Hehe, I've caught a big guy, think about how to eat it, let's eat it tonight. ”

Speaking of eating, Li Chengqian said without hesitation: "Then eat boiled fish, although the taste of dogwood is still a little worse, but it shouldn't be too bad." ”

Li Shimin nodded and prepared to go back.

He took out the booklet that had been prepared long ago from his bosom and handed it to the emperor.

"What is this?"

After looking at it, Li Shimin found that it was a record of various major events in the imperial court during this period of time.

"These are all things that happened during the period when the son was in charge of the country, and it is helpful for my father to quickly understand these things."

Li Shimin nodded, handed the booklet to Li Jian, and asked him to keep it well.

"During my absence, you have done a good job, whether it is Fang Xuanling or Gao Shilian, even Wei Zheng is full of praise for you. Being able to preside over the overall situation without problems shows that your ability to govern is not bad. It's just a pity, my body, it should be no problem to hold on for another thirty or forty years, if you want to succeed to the throne, I'm afraid you will have to wait until middle age! ”

Hearing the emperor's meaningful words, Li Chengqian said without hesitation: "I am happy to be under your protection." Don't say that you are middle-aged, if you are still there when your hair is gray, it is the blessing of your son! ”

Li Shimin smiled mysteriously: "You have filial piety." ”

After the conversation, the father and son continued to walk forward, obviously the breeze was blowing, it was very cool, Li Chengqian still felt that his back was wet.

It's too late, why do you ask such a question, I'm scared to death!

The warmth that lasted for six or seven years almost made Li Chengqian forget the nature of this emperor. He was burdened with infamy and took the throne by bloody means, which naturally looked more important than anything else. Are there still fewer rebels against him? Which one got the good end? Even if he was in the original history, didn't he change from a prince to a prince, and when he was finally buried, he was still buried with the ceremony of the prince?

Taking a long breath, Li Chengqian made up his mind that from now on, he would not mix with the court, and if possible, even the procedure of observing politics would be omitted. For the current self, it is a blessing and a curse to be mixed into the mess of the court too early. Just like the emperor's father said, he is really a natural candidate for the black pot.

After passing the palace but not entering, passing through the academy but not entering, just when Li Chengqian was confused, he found that the emperor had entered the medical school.

Now the medical school of the old Taoist priest has opened its door, and there will always be villagers or nobles who come to visit. The three-story inpatient building, which was forcibly built by the old Taoist priest, is now overcrowded, and the craftsmen of the Ministry of Industry are stepping up the construction of the second and third inpatient buildings like donkeys.

The first floor of the inpatient building is naturally only available to the nobles. Although he agreed to give special treatment, he turned back and made a dead deal on Xungui's medical fees. It is obviously wrong to discriminate treatment, but no one thinks that it should not be, the nobles feel that they spend more money in exchange for treatment, and they also think that this kind of behavior of the old way is a kind of robbery of the rich and helping the poor, and they should be supported, even if they are the one who is robbed.

The arrival of the emperor made many people unable to sit still, whether they were good or bad, they all struggled to the door to salute.

Without entanglement with these people, the emperor went directly into the innermost ward.

Outside the door of the ward here, a large number of people gathered, and those who went out of Beijing with the crown prince to greet the emperor today have basically arrived. It's just that there is no smile on everyone's face, but a dignified face.

Seeing the word "dangerous" on the ward, Li Chengqian remembered that it should be Zhang Gongjin.

He was already seriously ill, and he still ordered him not to go to court anymore and go to the medical school to see a doctor.

It's just, why did you suddenly transfer to the critical ward? Could it be that Lao Sun's methods have not ruled him well?

Just thinking about it, Sun Simiao happened to walk out of the door, and Zhang Daxiang, the eldest son of Zhang Gongjin who accompanied him, was very respectful.

Seeing the emperor, Sun Simiao just arched his hand, even if the salute was over.

Li Shimin sighed and asked, "Doctor Sun, how is Hongshen's condition?" ”

Sun Simiao also sighed: "It's too late, his illness can be traced back to more than ten years ago at the earliest, and it was not a fatal disease, but he has not had a good recuperation over the years, coupled with the hardships in the grassland back then, it can be regarded as a complete inducement to the accumulation of illness." Nowadays, even if he is an old man, he has a weak heart. At most, let him feel a little better during this time. ”

At this point, it can be regarded as a death sentence. If other doctors say this, maybe there is still a glimmer of life, Sun Simiao said this, Li Chengqian felt that any tertiary hospital in the future would be enough to choke on it.

Seeing that the emperor came to visit the sick, Zhang Daxiang did not bow down, but knelt on the ground and saluted. He knew that in his father's last period of time, the emperor was able to condescend to visit the ward, which had already given the Zhang family enough face.

It's very strange, but it's such a reason, even the officials in the corridor think that Zhang Gongjin is worth it.

Push open the ward, and a strong smell of alcohol can smoke people's heels.

Zhang Gongjin, who was lying on the hospital bed, looked much more energetic at this time, but his bloodless face proved that he was still a patient, and he was still a patient who stepped on the ghost gate with one foot.

Other patients are soup and water in front of their beds, but when they arrive at Zhang Gongjin, they become big fish and meat, as well as jars of wine. At this point, it's really time to eat and drink.

Zhang Gongjin was taken aback by the arrival of the emperor, and he struggled but couldn't get out of bed, so he could only stare at his wife beside the bed and ask her to help him get up.

"Lie down, when did I care about these etiquette?"

sat on the edge of Zhang Gongjin's bed, and reached out to pick up a jar of wine.

Zhang Gongjin sighed, and could only pick up a jar of wine.

The wine jars collided, making a dull sound, and they didn't speak, and the two of them poured a big sip of wine, and when Zhang Gongjin coughed, it was mixed with a little bloodshot wine syrup, and even sprayed onto the emperor's dragon robe.

Li Shimin didn't care about this, and put the wine jar aside before saying: "I haven't drunk with you once or twice, the most memorable thing for me is the celebration banquet after the Eastern Turkic War, Aiqing drank too much, and Xue Wanche said hand-in-hand that he wanted to dance in the Taiji Hall, but he danced like an old lady." ”

Speaking of the past, Zhang Gongjin's face flashed with a hint of reminiscence, but then disappeared without a trace.

"At that time, Weichen was not as weak as he is today, I remember that the first person to drink and vomit was your majesty! The last general is still willing to move forward for His Majesty and expand the territory for the Tang Dynasty, but how can this body eliminate this ambition. ”

Speaking of this, Zhang Gongjin couldn't cry. He is only thirty-eight this year, and he is not outstanding in the group of generals, but he was the first to withdraw from the team.

Li Shimin also sighed, and tears fell directly: "I'm sorry for you, just now Doctor Sun said that the biggest cause of your illness is the hardships of the Eastern Turkic War, and I shouldn't have sent you." ”

Li Chengqian, who was standing by the window with an expressionless face, was a little stunned when he saw the emperor's father crying so really.

At this time, I'm afraid it can't be mixed with "acting" and the like. can only show that he really pities his subordinates.

Zhang Gongjin, who was still crying, was also frightened when he saw the emperor crying, and hurriedly propped up his upper body and said: "It is the duty of the last general to share worries for Your Majesty, how can you blame Your Majesty?" Since Zhenguan, the last general has been rewarded for his merits, and he has never lagged behind others. Your Majesty doesn't owe the last general at all, if there is an afterlife, Zhang Gongjin is already willing to saddle the horse for His Majesty! ”

Hearing Zhang Gongjin's sonorous and powerful voice, Li Shimin wiped away his tears, turned his head to Zhang Daxiang and said, "I am blessed to have a good general like your father!" But how can you be a natural reader, and you can't inherit your father's last wish. But it's okay, the literary and military achievements are the same, and after graduating from the academy and the filial piety period expires, you will enter the court as an official! ”

Zhang Daxiang was grateful and knelt on the ground to salute.

Zhang Gongjin understands that when the emperor says such things in front of him now, he directly expresses that he wants to take care of Zhang Daxiang.

Being an official has sat to such a point, what else is there to regret?

After lying back on the hospital bed, I breathed a sigh of relief.

Zhang Gongjin closed his eyes.

The emperor stretched out his hand and tried it on Zhang Gongjin's neck, then got up and left the ward with a sigh.

Looking at the smile on the corner of Zhang Gongjin's mouth when he left, Li Chengqian understood. The emperor's father came over today, obviously to reassure him.

When the title reaches the level of a national duke, the first consideration is the issue of inheritance.

To tell the truth, without the care of the emperor, an unformed family may not be able to last, two generations!
