After Lu Dongzan's army withdrew, Li Yong's black army also left Tubo and retreated from the secret landing site outside Lanzhou in Tuyuhun. In Chang'an, the people received the good news that Tuyuhun was destroyed, the whole country rejoiced, Songzhou also received the news that the Tubo army left, anyway, the good news followed, Emperor Li Er was happy and almost amnesty the world, Li Jing's army returned to the dynasty and received Li Er and the people of Chang'an to welcome, for Li Jing, Li Er has no seal, just reward him with some land, gold and silver treasures and other things, Li Jing naturally knows what his situation is, he is sixty-three this year, this time Tuyuhun's war of annihilation, It is also the last battle of his life, although Li Yong robbed Fu Yun's head, but overall it is good, Li Yong did not finish all his work, otherwise he would be more aggrieved, he resigned from all positions to Li Er after returning to Chang'an, Li Er of course happily agreed, because Li Jing's influence in the army is too great, that is, he can suppress it, but if it is replaced by his sons, it is estimated that his surname Li Datang will be finished, in fact, he has paranoia of being killed, in fact, Li Jing didn't think so at all, Even if he thinks that his age will not live to his second son to succeed to the throne, Li Er purely thinks about it. After Li Jing resigned from his official position, the door of his home was open all day long, indicating that he Li Jing did not do anything behind the emperor's back, Li Jing's good intentions made Li Er embarrassed, but it was also this move that made Li Er unhappy, because you did this, put my benevolent emperor's face in the cabinet? Li Jingyou doesn't care so much, he writes books at home all day long, and writes his life's experience into a military book for future generations, which can be regarded as what he wants to do in the second half of his life.

"Li Jing has returned to his hometown, and he has been tinkering with those military books at home all day long, and we old guys have almost given way to young people."

Li Daozong, the king of Rencheng, also came back with the army this time, stayed in Chang'an for a while and then went back to Liangzhou, he went to Li Xiaogong's house as a guest if he was fine, who let his family have money, indeed, Li Xiaogong followed his son-in-law to the sea, made a lot of money, many people envied him for having a good daughter, which made the old man proud of his predecessors and queens, since the last time he ran to the sea and made a lot of money, and then he added some boats, his fleet has sailed out to sea again with Li Yong's fleet, Li Xiaogong listened to what his cousin said, He had long been a stranger to his cousin, so he didn't care.

"Cousin, aren't we already a supreme minister now? What else do you want? Li Jing, that guy is a smart person, isn't it good to eat and drink at home? It will be good for you and him to hand over the military power in your hand as soon as possible, so listen to my brother's advice. ”

Li Daozong didn't know what Li Xiaogong said, but he finally became the governor of Liangzhou, although it is located in a remote area, but it is a feudal official, so power is poison, once people taste it, they can't stop, not everyone wants Li Xiaogong and Li Jing are people with great wisdom, Li Xiaogong also knows his cousin's mind, he is also testing himself, he doesn't really want to be the same as Li Jing, Li Xiaogong was like resigning from the position of Zongzheng Temple Dazongzheng, but Li Er didn't let it, Anyway, Zongzheng Temple is fine, so he basically doesn't go, so he lets other people handle things for him, and counts money and plays with women at home. After Li Yong returned to Huating County, after Changle and the others saw him come back safely, their hanging hearts were put down, and the Hou Mansion of Huating County resumed its old laughter again, and after Li Yong rested for two days, he began to deal with the backlog of government affairs when he left, in fact, most of the government affairs were handled by Gao Gao and Zheng Liwan, and only some that could not be handled were left for Li Yong.

"Lang Jun, that mysterious organization is a bit eyebrow-raising."

Li Yong looked at the thick pile of information and information that Zheng Liwan gave him, looked at it carefully page by page, and asked from time to time.

"How did you find this?"

"It's also a coincidence, do you remember the pirate sneak attack? There is a group called the Hell Devil Pirates, their leader is called Boss Lin, he is one of the members of the mysterious organization, but unfortunately we were killed, and later when we cleared the pirates' lair, the intelligence bureau found some clues from it, I found that this person is related to the mysterious organization, I asked people to re-interrogate the remnants of the Hell Devil Pirate Group in the labor camp, and finally found out the relationship between them. ”

"Well, I also found some things in Tuyuhun, they instigated the Tuyuhun and Tubo people just to get our firearms, and now after Tuyuhun, Tubo, Western Regions, Xue Yantuo, and Goguryeo have been attacked, some of our firearms that we didn't have time to destroy were obtained by them, so their purpose is easy to know, they are afraid of our weapons, and I hinder them, so they treat me as a thorn in the flesh."

Li Yong combined intelligence analysis that this organization spent so much effort just to get firearms, fortunately they only captured the old muskets, and there were no artillery, and it was not so easy for them to imitate muskets, first of all, the process of steel, if Li Yong didn't know some of the iron and steel smelting processes of later generations, plus recruited a large number of experienced craftsmen, many experiments and money investment, they only got the basic conditions for the production of muskets and artillery, even if they could have this ability, The other gunpowder ratio problem is not so simple, although the material of gunpowder is not complicated, but the ratio problem has to be constantly debugged, and then take a step back, even if they all get these out, then Li Yong's firearms must have been upgraded again, and the musket with black powder against the yellow smokeless gunpowder of the Xishan Nine style is completely pressed.

"I found out about this organization, and it's called Heavenly Roar."

"Roaring in the sky, roaring towards the sky, quite a big breath."

Zheng Liwan didn't know what it meant to roar towards the sky, Li Yong explained to her.

According to legend, there is a big difference between this roar and a dragon, its horns are like a deer, its head is like a camel, its ears are like a cat, its eyes are like a shrimp, its mouth is like a donkey, its hair is like a lion, its neck is like a snake, its scales are like a carp, its front paws are like an eagle, its hind paws are like a tiger, and it is a super powerful monster that can breathe fire. The dragons were afraid of him because he could eat them. It is recorded in the book that there is a beast in the East China Sea, which can eat dragon's brain, take off up and down, and the eagle is abnormal, every time it fights with the dragon, it breathes fire in its mouth for several feet, and the dragon is invincible. What is the Son of Heaven? What do they mean by that name? ”

After Zheng Liwan heard this, she immediately understood, it turned out that they were going to eat the dragon's organization, and eat the roar of the dragon of the Tang Dynasty, no wonder Li Yong said that they had a big tone.

"So, what this group of people are going to do is indeed dangerous, will the saint know?"

Li Yong put aside the information he had read and did not answer Zheng Liwan's question, because he didn't know if Li Er knew or not, but he preferred to know, because who was Li Er? Emperor of the Ages, how could anyone who threatened his throne not know? But he can't be sure, because this roar is too mysterious, and what he does can be described as dripping water, so that people can catch any useful clues, if they weren't for these mercenaries who couldn't help but shoot at Li Yong, Li Yong would not have been able to grab their little tails, plus Zheng Liwan's carefulness and the powerful function of the Intelligence Bureau finally knew the name of this organization, but how many people they have, where the base is, I don't know at all, the entire Tang Dynasty is so big, if there is anything overseas, it is simply looking for a needle in a haystack, So Li Yong doesn't have any more clues now, but it's not like no progress, at least he knows what people call him.

"It's been hard for you this time, and these things should have been done by others."

Zheng Liwan sat down next to Li Yong and leaned on his arms, Li Yong smelled the fragrance on her body, knowing her character, she couldn't be persuaded, so he didn't persuade much, just hugged her to enjoy the peace of mind at this moment, because he knew that the current peaceful life would not last long, because these people would not let him develop with peace of mind, they would do everything possible to use all kinds of dirty means to get what they wanted, so this made Li Yong hurry up and time was very urgent, especially the symbol that symbolized the first industrial revolution, the steam engine, He has proposed this concept and basic design drawings to the research institute, but there are no rubber and process problems, the progress is very slow, even if there is Li Yong's design drawings and working principles to provide, but really make it, it is completely different, Li Yong has no other way, he can only wait now, he is more optimistic about the future of Xishan University, as long as there are talents, then he will be invincible in the world in the future, even if he does not be the emperor, but the emperor is afraid of him for three points, because it really can't slip, In this era, there is no great voyage, many continents are occupied by natives, and he can hide anywhere, so only his own strength is the greatest guarantee for himself and his family, but if he does not meet the standards, he agrees with the only organization that roars at the sky, their purpose is to overthrow the Tang Dynasty, which Li Yong cannot allow them to do, at least Li Er is good as the emperor, if they do this, the world will be destroyed in a hurry for more than ten years, and then the world will be in chaos and the people will be displaced.

"Liwan, let's let the people from the Intelligence Bureau look for clues to the roar in the sky, you don't have to pay too much attention to it, because what we have to do can't be dragged down by them, this is their scheme, they get those muskets, it will take at least more time to make actual progress, so we want them to grab time now, we want to strengthen our business empire, the army has Xue Rengui and Liu Renliang they preside, we don't have to interfere too much, and we don't have to worry too much about the loyalty of the army."

"Well, don't worry, now that Wu Cao's little girl has also come over, and now she has also started, I will divide the work with her, and I can share some work for you, and you can do your thing with peace of mind."

Such a wife, what more could a husband ask for, Li Yong was moved to tears, the two of them left the study after a while, and when they came out, they provoked the strange eyes of the rest of the women, Li Yong looked at them like wolves seeing flesh, he hurriedly slipped away, thinking that these women have really big hearts, but Li Yong wanted not to let them worry, so only he and Zheng Liwan knew about the matter of yelling at the sky. The thing that roared towards the sky pressed on his chest like a big mountain, which was the biggest problem since he came to Datang, because he knew that there was such an enemy, and he also knew the purpose of the enemy, but where was the enemy? He didn't know what anyone was in the collective, so he was very crazy, Li Yong didn't go there every day, and he continued to improve the five-year plan that had been determined at home, and now he could only make adjustments, because the enemy in front of him gave him not much time, because once the musket was imitated, it would be a devastating blow to the army of the imperial court, and cold weapons were not at the same level as hot weapons, because the experience of the black army knew that it was completely crushing, if they had a huge army, and then equipped with sharp muskets, That was simply fatal, not to mention that Li Yong suspected that the magic arm bow and catapult technology he gave Li Er had been leaked, and the army of the imperial court would not have to fight at all in the face of an enemy with such weapons. The enemy is changing, Li Yong also has to change, that is, to improve his own science and technology tree, the most important thing is to represent the industrial revolution of the steam engine, if there is a steam engine, their own industry has the same quality as flying, then the internal combustion engine, and finally electricity, now the top priority is the research and development of the steam engine, the steam engine is not responsible according to the principle, it is the problem of sealing, so the material problem is imminent, first of all, the reserve of strategic resources, coal mines, iron ore and the back of the oil, and there is rubberFortunately, now the sea is open, coal and iron ore Li Yong has plundered back from various channels, and then established a large number of strategic material reserves in the valley of Xishan, a large number of coal mines and iron ore are almost full of his reserves, he must not continue to expand new material depots, he intends to join the research and development of steam engines in the next time.
