Although Zhang Liang has a heart of disobedience, after all, there is no real rebellion, plus his previous merits, so Ping An Lang feels that he is guilty of not death, but Li Shimin smiled indifferently after hearing this, and then looked at Li Xiu, it seems that he wants Li Xiu to teach Ping An Lang.

As a father, it was his responsibility to teach his son, so at this time, I saw Li Xiu stretch out his hand and pat Ping An Lang's shoulder and said: "Ping An Lang, on the surface, Zhang Liang is indeed guilty of not causing death, but in addition to the above crimes, Zhang Liang has also received 500 names over the years, if you don't have the intention of rebellion, why raise so many people?" ”

"This ......" Ping An Lang couldn't help but be stunned when he heard his father's words, just now Li Shimin said that Zhang Liang has a lot of righteous sons, but he really didn't pay much attention to it, but he didn't expect that there were as many as five hundred, this is not a small number, you must know that Li Chengqian rebelled at the beginning, but only collected more than 100 dead soldiers, but Zhang Liang received 500 nominal sons, these 500 people are likely to be placed in the army or places by Zhang Liang, this is enough to cause the court to be vigilant.

"Zhang Liang, self-defeating, not worthy of sympathy!" Li Shimin also suddenly said at this time.

In fact, if it was only because Zhang Liang had a heart of disobedience, Li Shimin would probably not have a murderous intention on his past merits, at most he would be demoted to a concubine, but Zhang Liang took a dead end and actually accepted 500 people, these people are either in the army or in the locality, and these people are uneven, many of them rely on Zhang Liang's power to do nonsense, which has formed a great harm, plus Zhang Liang himself has a heart of disobedience, this is the main reason why Li Shimin is determined to kill him.

Ping An Lang is also an extremely smart person, after getting the guidance of Li Xiu and Li Shimin, he immediately understood, and nodded at the moment, and he also thought of one point, that is, now that Li Shimin is old, it can be said that it is now the time when the Tang Emperor is changing between the old and the new, and naturally he cannot tolerate any potential threat, but Zhang Liang has committed this big taboo, and it is no wonder that his father and father-in-law are so ruthless.

"Erchen understands, thank you for your father and father's guidance!" At that moment, Ping An Lang also expressed his gratitude to Li Shimin and the two, these things seem simple, but in fact they are intricate, if it were not for the guidance of Li Xiu and Li Shimin, I am afraid that it would be difficult for Ping An Lang to understand it alone.

Seeing that Ping An Lang had already understood the reason why he wanted to kill Zhang Liang, Li Shimin also nodded happily, but then he thought of the second thing he came to find Li Xiu today, and said with a little joy on his face at the moment: "Li Xiu, I just received the news that Xue Yantuo's Yi Nan is dead!" ”

"Really!" Li Xiu couldn't help but be overjoyed when he heard the news, since the Turks were destroyed, Xue Yantuo has become the overlord of the grassland, although he surrendered to the Tang Dynasty on the surface, but the two sides are constantly rubbing, and Yi Nan is indeed a man of great talent, even if he has suffered a huge blow several times, but he still survived, and he has become the biggest threat to the Tang Dynasty after the Turks.

Of course, Li Shimin also wanted to send troops to destroy Xue Yantuo many times, but the Mobei grassland was too far away, and the expedition of the Tang Dynasty Labor Division was really unwise, so in the end, he could only dispel the idea of sending troops directly, and instead secretly contacted the Hui and other tribes to suppress Xue Yantuo.

"Hahaha~, it's true, several pieces of information from Feinusi have confirmed that Yi Nan is dead, and his eldest son Ba Zhuo has inherited his throne, but Yi Nan is not only a son of Ba Zhuo, but there is also a son named Lu Mang, this Lu Mang is not born to Yi Nan's wife, but he is very favored by Yi Nan, and he has many tribes in the east of Xue Yantuo in his hands, and now this Lu Mang is not convinced that his eldest brother will take over the throne, and there is also tension between the two!" Li Shimin laughed again at this time.

Yi Nan's two sons have long been in his sight, and even Fei Nusi has already been in contact with these two people, and now the two of them are at odds over the throne, which is also in his hands.

"Great, Yi Nan's two sons are not in harmony, as long as they provoke a little from it, they will definitely be able to kill each other, no matter who wins or loses, it will make Xue Yantuo's vitality greatly damaged, even if we don't send troops in Datang, I'm afraid these mortal enemies will not let them go!" Li Xiu also shouted in surprise again at this time, if Xue Yantuo is not destroyed, the Tang Dynasty will not be able to unify the grassland, and now is a good opportunity to destroy Xue Yantuo.

"Yes, I think the same way, you and Wuji once offered me a three-step strategy to conquer the grassland, but unfortunately although the first step exterminated the Turks, the second step is to divide and disintegrate the forces on the grassland, so that the entire grassland becomes a plate of scattered sand, and there is no longer a force that can threaten our Tang Dynasty but it has not been completed, it is because of Xue Yantuo, now as long as Xue Yantuo is destroyed, the grassland can be completely turned into a plate of loose sand, and then you can implement the third step you said!" Li Shimin also said excitedly at this time, when he and Li Xiu and the eldest grandson Wuji set a strategy for the grassland, although the progress has been difficult over the years, he has not forgotten it.

"Father, what kind of strategy did you and your father set at the beginning?" Hearing the conversation between Li Xiu and Li Shimin, Ping An Lang asked with some puzzlement, after all, he couldn't understand what they were saying at this time.

"Hehe, in fact, it's nothing, but when Your Majesty just ascended the throne, the Turks threatened us many times and became our henchmen, in order to completely solve the threat of the northern grasslands, so we discussed with Your Majesty many times, and later the eldest grandson Wuji proposed a three-step strategy, which is to destroy the Turks, divide and disintegrate the big forces on the grassland, and finally annex the grassland, so as to completely eliminate the threat of the northern grassland!" Li Xiu smiled at this time and explained to Ping An Lang that these things in the general direction let him know, and it will also be conducive to his grasp of the government in the future.

"Father, you are really long-term, you already had such a long-term vision when the Turks were not destroyed, and your sons and daughters are obedient!" Ping An Lang couldn't help but be amazed when he heard Li Xiu's words, and then he also respectfully saluted Li Shimin and Li Xiu, he really didn't expect that this strategy for the grassland had been set more than ten years ago.

"Like the grassland, a stubborn disease that has threatened the Central Plains for many years, it is natural to have a long-term plan, and you have to learn more from your father, after all, it was your father who first put forward the idea of completely solving the northern grassland, so that there was a three-step strategy proposed by Wuji later, and in the current situation, it is quite rare for us to complete the first two steps, as for the third step to annex the grassland, it is easy to say, but it is extremely difficult to do, which needs to rely on you and the pheasant slave to work together!" When Li Shimin said the end, he couldn't help but show a sad look on his face.

At the beginning of the Xia, Shang and Zhou dynasties, there were enemies on all sides of China, respectively called Dongyi, Nanban, Xirong, and Beidi, but later through the efforts of the ancestors, the enemies in the east, west, and south were almost all destroyed, even if there were still some remains, but the threat to the Tang Dynasty was not great, but only Beidi, that is, the enemy on the northern grassland has not been able to be destroyed, even if the Central Plains has repeatedly beaten the enemies in the north and fled, but as long as the Central Plains does not control the grassland, there will be new enemies in the north sooner or later.

Li Shimin is a rare male lord in the history of the Central Plains, he made up his mind from the time he ascended the throne to sweep away all the enemies around the Tang Dynasty, and lay down a peaceful country for future generations, so he was not satisfied after destroying the Turks, but wanted to completely annex the grassland, so as to destroy the last big threat in China.

It's just that the northern grassland is not only vast in area, but also the folk customs are also very strong, it is too difficult for the Tang Dynasty to annex here, and it is difficult to complete it even by his generation alone, especially now that he is older, he feels even less energetic, so Li Shimin said that the annexation of the grassland depends on Li Zhi and Ping'anlang's generation.

"Father's words are serious, you and your father are not yet fifty, and it will be time to slowly annex the grassland in the future!" Ping An Lang also noticed the sadness on Li Shimin's face, and immediately opened his mouth to persuade.

"Hahaha~, you and your father are really similar to this, they are very comforting, but to be honest, at my age, I'm afraid I want to completely annex the grassland, but even so, I will make a detailed plan, and then you and the pheasant slave will also be involved, let's join forces for two generations, I don't believe in swallowing the grassland!" Li Shimin first laughed, and then showed a resolute expression and said, as long as he is determined to do something, he will never give up halfway.

A few days later, Zhang Liang's charge of rebellion was confirmed, and then the whole door was beheaded, and most of his five hundred righteous sons were killed, which also set a warning to the nobles of the Tang Dynasty, telling them what they can do and what they can't do, after all, Li Shimin even dared to kill a hero like Zhang Liang, let alone others, which made many people relent, and at the same time paved the way for Li Zhi's future accession to the throne.

And Xue Yantuo's side with the death of Yi Nan, although Bazhuo inherited his throne, but it was difficult to convince the public, especially his younger brother Lu Mang several times, so that their brothers were also like fire and water, and Fei Nu Si also began to show their skills, and soon Ba Zhuo and Lu Mang finally fought, Lu Mang controlled the major tribes in the east of Xue Yantuo, although the strength was a little weaker than Ba Zhuo, but it was also very limited, so the two sides were also inseparable.

Seeing that Xue Yantuo really fell into civil strife, Li Shimin was also overjoyed, and then discussed with the ministers about sending troops, but for the matter of whether to send troops, the court was arguing, and there were many people who supported and opposed it, and no one on either side could convince anyone!
