Just when Right Wuwei was building a confinement room in full swing, in Chang'an City, something related to Li Kuan was also happening.

When Li Kuanqi opened Chang'an, he once said that a bag was handed over to the eldest grandson and asked her to help transfer it to Li Er, although the things in it were not a military matter, but they were almost there. This time the thing is Li Kuan's revenge, he is a relatively small person, if anyone offends him, he will always remember it, and then wait until he has the ability or the time is ripe, and then retaliate back. Of course, it doesn't mean that if you glare at him, he will kill your whole family, but that he will do to you what you do to him. Depending on the circumstances of the situation, he will take different ways to retaliate.

Just like before, Cheng Yanjin had some verbal disputes with him at a banquet with Li Er seven years ago, and he also knew that Cheng Yanjin was not embarrassed, but his gag personality was weird, and he didn't really mean to be embarrassed. So Li Kuan just arranged a little story about Cheng Biting Jin and made him ugly once.

And what he gave to the eldest grandson was his revenge on the eldest grandson's family, this guy was also bad-hearted, the eldest grandson treated him well, but he had a bad taste for a while, and let the eldest grandson act as an accomplice in his revenge on her brother. It's just that I don't know if this time, the eternal sage, who has always been lenient to him, will treat him as always after learning the truth. It's just that Li Kuan doesn't regret it, in addition to his bad taste, he also has other thoughts: I hope that the eldest grandson won't be so good to him anymore, otherwise in the subsequent incident, he will hurt her even more. This incident is to remind her that the eldest grandson can feel something different from it. Although Li Kuan knew that he might not be able to stop it. But he must do it, and it concerns the people he cares about the most. At least the people who care the most in this day and age.

Having said all that, I haven't said what exactly is in that bag! In fact, Li Kuan had already made this thing. It's just that the time is not ripe enough to get it out. That is the soil method of steel, which is commonly known as the steel frying method. Before the Tang Dynasty, steel was called iron, and the most famous of this iron must be clear to everyone, that is, in the Romance of the Three Kingdoms, the Martial Saint Guan Yu's Qinglong Yanyue Knife. According to legend, its predecessor was two forty-pound iron rods, which were made into the famous 'Lengyan Saw' by an unknown old blacksmith, and it was passed down to future generations along with Guan Gong's name. This thing is very difficult to get, and the output of Datang's steel has been low. The annual output is not more than 10,000 catties. However, the steel frying method provided by Li Kuan can produce 100 catties of steel per day, and the three of them can produce 36,000 catties this year. Compared with the sum of countless skilled craftsmen in Datang now, it is three times more, and this is only three people. If only thirty. What about three hundred? This allows Datang's military weapons to be updated faster, and the hardness of the iron is much worse than that of the weapon made of steel.

With this method, Datang's national strength will undoubtedly be greatly improved!

Therefore, although this thing is not directly related to military affairs, the indirect weight is not bad at all. Give this bag to the eldest grandson and let her pass it on. Li Kuan believed that she would not steal it, but it was undoubtedly taking advantage of her trust in Li Kuan. Let her hurt her own brother, the man who has been revolving around her all his life. The man who carried her to play when she was young, stayed in front of the couch when she was sick, worried about her, stood up for her when she was wronged, and protected her tightly in his arms to prevent her from being hurt in the slightest bit. After she got married, she assisted her husband without hesitation and helped him pacify the men in the world.

In this way, the eldest grandson will undoubtedly be very sad, and even blame Li Kuan, but this is also a helpless thing, although the eldest grandson's feelings for Li Kuan are not as deep as their biological mother and son, but they are not shallow, and this kind of slow estrangement is easier to accept than smashing the light blows between the two at once. At least this time it just gave the eldest grandson Wuji a headache for a long time, and there was nothing else to lose except money.

That's right, this steel method is in the world, and the biggest loss is the eldest grandson Wuji's family, who has gradually become the largest iron supplier in Datang in recent years, in the industry of the eldest grandson's family, mines and smelting, as well as weapons and armor to build occupy most of the country, this is also because the eldest grandson Wuji, the uncle of the country, dares to reach into this armament casting, if others will definitely be accused of privately casting armaments, there is a rebellion. But no one dared to say that the eldest grandson Wuji was the queen; Second, the qiē he made was completely transparent to Li Er, and every ten years he would report to Li Er how many ores he had dug and how many weapons he had minted, and all of them would be sold to Li Er at a suitable price.

With these two items in mind, who would dare to say that he had the intention of rebellion? Therefore, the eldest grandson Wuji relied on this iron business to have a large amount of money and grain every year, but Wei Zheng and other officials were impeached by him. This is also his wisdom as an official, for the rest of him he is a smiling fox, stabbing a knife in the back with a smile, but to Li Er and the eldest grandson. The eldest grandson Wuji is also heart-to-heart, loyal, and unmatched. For the Tang Dynasty, it can be said that in addition to Li Er, who is sitting on the throne, and the eldest grandson of the queen, he is the most loyal. As long as the Tang Jiangshan Sheji needs it, his eldest grandson Wuji can even die and take the entire eldest grandson's family to Huangquan together. This is not something that ordinary people can do, let alone those who have such a small plan in their hearts.

So even if Li Er later died in history, he supported Li Zhi to the throne, and his power at that time could be said to be in favor of the government and the opposition, if he wanted, he could even replace Li Zhi when his foothold was not stable, but he didn't, not only because Li Zhi was his nephew, but also because he and Li Er, and the eldest grandson, and the relationship between the Tang Dynasty and the society.

Of course, these are all later words, maybe it will happen, maybe it will change, who says that there is a guy who is not under the crush of the wheel of history!

At this time, Li Er's face was full of red light, listening to the report of Yan Lide, a master craftsman of the Ministry of Industry, and after more than half a month, he finally achieved results today.

"Qi Xiang Xià, the ministers and others have studied this formula for more than half a month, and finally got through the tricks, opened the furnace this morning, and finally baked 30 catties of fine iron just now. According to this time, three people can open the furnace to refine more than twice a day, which is still not skilled, and the time will be shortened in the future to be able to refine three furnaces and get 100 catties of iron. It's unimaginable! God bless the Tang Dynasty, the minister is His Majesty, and he is the Tang Dynasty! With this method, the combat power of the army will be doubled, and the barbarians from all directions will be cleared up in the near future! Yan Lide was dressed in a scarlet robe with a gold belt of eleven rings. Yan Lide was born in an aristocratic family, but he loves architecture, craftsmanship, and has a high attainment in painting, but he is not as good as his younger brother Yan Liben. What he is best at is construction, and the drawings of the Lin De Hall that Li Er wanted to build a few years ago are his handwriting. So he worked in the Ministry of Industry and was responsible for the size of the Ministry of Industry.

"Really?" Li Er stood up from the throne at once, this news is really good news for him, this year seems to have been overpowered, since he ascended the throne, Jieli went south, locust plagues, and droughts all came all over again. Moreover, a group of officials led by Wei Zheng in the court are always picking on his thorns, and he must not have seizures, so there has not been much good news in the past few years. Zhenguan's three years have been uneventful, with neither disasters nor bumper harvests, and the results of suppressing foreign tribes are also mediocre. It's been half of the four years since Zhenguan, and I've finally heard something nice.

"It's true, what Weichen personally watched by the side is indeed the best iron. If it is used to forge weapons, it is comparable to the standard weapons used by the captains today. Yan Lide replied respectfully.

The production of iron in the Tang Dynasty is limited, so the weapons used by ordinary soldiers are only iron weapons, only the official to the captain level, and the above generals and officials will have iron weapons, which is also no way, iron is a good thing, but there are only so many, how to divide it is not enough, and the loss of weapons is also very strict, a battle is fought, the broken swords on the battlefield are countless, who dares to let ordinary soldiers use weapons made of iron!

"Good! Good!! Good!!! Li Erlian said hello three times, laughed and walked out of the door of the Lizheng Palace, he wanted to go out of the palace to see, such a good way to hide his two boys in his hands for so long. When the bag was handed over to Li Second, Li Er knew that Li Kuan had been preparing this thing for a long time, because the ink on the paper had already dried out, and there was a faint musty smell that had been left for a long time. Of course, this is also because Li Kuan's Xiancai Hall is too deserted, and only he and Xiao Tianxiang live in the huge palace, and when this bag was moved to the Xiancai Palace, it was directly put into the warehouse, and it was not until Li Kuan remembered it when he left this time, and he went to turn it out. Li Kuan didn't pay attention to these, but was noticed by Li Er, who was as careful as a hair. In Li Er's inference, this thing has been hidden for at least three years, which makes Li Er feel a little uncomfortable, three years, enough to produce hundreds of thousands of catties, millions of catties of iron, enough to replace the equipment of the left and right guards who went out this time, how many soldiers will die less! Li Er decided to wait for Li Kuan to come back and settle the account with him, so that he knew that there were some things that could be hidden and some things that could not be hidden. But Li Er didn't show it, and he was still very happy to stride towards the outside of the palace. He was about to walk, and refused the guard's request to prepare a horse. This would make the anticipation in his heart more permanent, and although he wanted to see the iron come out immediately, he also wanted to feel more of the joy that was about to move in his heart now.

Li Er was happy, but the eldest grandson Wuji was sad, and when he received the housekeeper's report, he was directly stunned on the Taishi chair. (To be continued......)
