After learning about the rumor, Li Su asked Wang An to discuss, and the two agreed that they must keep a low profile when they return to Chang'an this time, and try not to contact anyone with sensitive identities, after all, rumors can kill people, especially in the matter of changing the throne, no matter what, you must be careful and careful, so he returned to Chang'an like a thief.

The first thing he did when he returned to Chang'an was to enter the palace to report to Li Shimin, and then he told Li Shimin in detail about the attack on the night of Weizhou, and also told the results of the interrogation, but Li Su finally said that although all the evidence pointed to Li Chengqian, he believed that this matter was definitely not so simple.

Li Shimin was silent after hearing this, and after a long while, he patted Li Su's shoulder and said: "Liulang, fortunately you encountered this matter, so you didn't let the other party's trick succeed, if you let your fourth brother meet, then I don't know how big a mess it will be?" ”

Li Su was stunned for a moment after hearing this, and then immediately asked anxiously: "Father, listening to the meaning of your words, do you already know who is behind this matter?" ”

After hearing this, Li Shimin sneered, and said: "Liulang, when the other party attacked you, whether it was time or place, they made careful arrangements and preparations, it is certain that the other party is not only very familiar with your itinerary, but also did a lot of investigation in advance, but under such a precise investigation, how could the other party not know the number of guards around you?" ”

When Li Su heard this, a flash of inspiration flashed in his mind, as if he had thought of something, but he couldn't grasp it.

Li Shimin didn't notice Li Su's hard thinking, and then continued: "Since the other party knows the number of guards around you, but in the end he actually sent the Yellow River Gang to attack you, my father has already investigated, although the Yellow River Gang is a brave and ruthless gang, but it is simply a fool's dream to use more than a thousand people to defeat your thousand guards. If the other party really wants to kill you. And how did you send this rabble to attack your fleet? ”

Li Shimin's words were like helping Li Su open a window, and suddenly blew away the fog in Li Su's heart, and saw the truth that he had been unable to see clearly. According to Li Shimin, the other party actually didn't want to really kill himself at all, but wanted to achieve their deep-hidden purpose through this assassination.

"Father, what do you mean is that the other party wants to use this incident to provoke conflicts between his sons and eldest brothers. Or even a battle for the throne? Li Su gritted his teeth and said with a murderous expression. If it weren't for Li Shimin's reminder, he really didn't expect this, and at the same time, he also regretted it a little in his heart, because he decided to keep this matter secret, so he never mentioned it to Wang An, otherwise with the wisdom of the other party, he would have seen the real secret behind the assassination.

However, Li Su's words had just come out. Immediately another question came to mind. I couldn't help frowning and asked again: "But Father, the sons and daughters can't understand a little, what good is it for them that the other party provokes a battle for the throne?" ”

Li Shimin laughed when he heard this, his son has always been smart, and getting along with him is not like facing his own son at all, but like an opponent on equal footing. But no matter how smart he is, he still lacks in these conspiracies, after all, he is still too young, and it is normal not to understand, at this time, looking at Li Su's puzzled appearance, he finally has a feeling of a father teaching his son.

"Rokuro. Don't be misled by the other party, think about it, if you are involved in the struggle for the throne, then do you have the energy to do anything else? Li Shimin had an unfathomable expression on his face, the real purpose of this attack was actually on Li Su, because the other party wanted to take advantage of this matter to shift Li Su's attention to the throne, and then they would wait for the opportunity to do something else.

"Five surnames and seven hopes!" Li Su said viciously, now he finally figured it out, although he didn't know which of the five surnames and seven wangs did it, but the real culprit behind the scenes must be among them, of course, it may also be two, three, or even several companies joined forces to do it, and the purpose of what they did was actually very simple, that is, to let Li Su fall into the battle for the throne, and have no time to deal with their next suppression of industry and commerce.

"Hmph, a few days ago, some officials from a family wrote a book, saying that the domestic industry and commerce were rampant, causing farmers not to think about farming, but only thinking about strange and obscene skills, which led to a big reduction in domestic grain production, so let the imperial court order to limit the scale of industry and commerce, etc., although these are just small people, but the meaning of the temptation is very clear, presumably more people will be mobilized to put pressure on the imperial court in the future."

Li Shimin sneered with a bit of murderous spirit, originally he was a little worried about the development of industry and commerce, and was thinking about whether to restrict it, after all, agriculture is the foundation of the country, but those big families are really too deceitful, in order to achieve the purpose of suppressing industry and commerce, since they did not hesitate to provoke a fight between the princes, and even dared to send someone to attack Li Su's fleet, it can be seen that the other party did not take their Li royal family seriously from the bottom of his heart, which made Li Shimin very annoyed and made up his mind in his heart. No matter what, we have to suppress those big families.

Li Su was angry, but also deeply felt for the first time that the methods of those big families were enough to be called scheming and ruthless, if it weren't for the fact that he didn't have any covetousness for the throne, I am afraid that they would really succeed.

If you don't fight back after being beaten, this is not Li Su's character, but it is best to have the support of the emperor's father in this matter, otherwise there may be problems. So Li Su didn't rush to see Concubine Yang, but talked secretly with Li Shimin for a long time, not only told Wang An's three strategies at the beginning, but also talked about some of the methods he thought of.

However, after the excitement, Li Shimin severely criticized Li Su, the reason is that there is such a good way, why not take it out earlier, otherwise they Datang would not have to worry about food problems a long time ago.

After talking about these, Li Su said what he thought of, and told the counterattack method of the five surnames and seven wangs, although in Li Su's view, it was just two very ordinary methods, but in Li Shimin's ears, it was like an initiation, but the cost of these two methods was not a small amount, although with the development of industry and commerce, the treasury income has also increased greatly, but just after the battle of Goguryeo, the treasury is really not very rich, and so much money is taken out at once, which makes Li Shimin a little reluctant.

However, these two methods are both meritorious in the present generation, and beneficial to the country and the people in the future, if they can be held as soon as they are held, not only can the influence of the family be minimized, but also their old Li family's country will be more stable. Thinking of this, Li Shimin finally decided to agree.

Seeing Li Shimin's somewhat painful expression, Li Su grinned and said: "Father, in fact, these two things don't need to be spent too much by the imperial court, as long as you hand over this matter to your sons, not only can you save a lot of money, but also can do these two things as quickly as possible!" ”

"Oh, what can you do?" Li Shimin's eyes lit up after hearing this, he knew that his son's other skills were just that, but when it came to the ability to make money, he was definitely the first in the world, I heard that there are many businessmen who have said that Li Su is the god of wealth, no matter what it is, as long as it passes through Li Su's hands, it will immediately become a hundred times more worthy, and now he can come up with a way to help himself save money, it is estimated that it will be a piece of cake for him.

"Hehe, Father, there are surprises to be fun, and I'll tell you now, isn't that too boring?" Li Su said with a grin.

Li Shimin laughed after hearing this, since Li Su refused to say, then he wouldn't ask, anyway, he was relieved of this son, knowing that he would not mess around, and the way to attack the family was also thought up by him, and it was reasonable for him to be responsible.

After chatting about business, Li Shimin was ready to let Li Su leave, after all, Concubine Yang was still waiting for her son who had not seen her for more than a year, but just as Li Su was about to leave, he saw Li Shimin stop him with a somewhat embarrassed face, and said hesitantly: "That...... Liulang, your mother may talk to you about something, don't be too surprised for a while, be mentally prepared first! ”

Li Su was stunned for a moment after hearing this, and asked strangely: "Father, what does the mother concubine want to talk about with her son?" ”

"Hehe, this ......" Li Shimin's face was very strange, and he seemed to be a little helpless, "You will know when you go, but your mother is now pregnant, don't disobey her temperament, otherwise not only will you be unlucky, but you will not even be able to live in peace as a father!" In addition, you are absolutely not allowed to say anything about what happened in Pyongyang! ”

Li Su felt even more strange in his heart after hearing this, but looking at Li Shimin's appearance, he definitely couldn't ask anything, as for the Pyongyang incident mentioned later, it was naturally the affair between him and Queen Silla, and Li Su didn't dare to say it to Concubine Yang when he killed Li Su, so he didn't need Li Shimin's reminder at all.

In desperation, Li Su had to thank Li Shimin for reminding him, and then turned to leave, but he didn't notice that when he thanked him, Li Shimin's face flashed with a little guilt.

Li Yu came out of Li Shimin's Liangyi Palace, it was almost noon now, and his stomach was hungry, just enough to go to Concubine Yang for a meal, but now that Concubine Yang is pregnant, she must not be able to cook in person, which is a pity, he has always liked to drink the chicken soup stewed by Concubine Yang herself.

When Li Su arrived at the Wangyun Hall where Concubine Yang lived, he was told by the palace maid that Concubine Yang was not in the palace at all, but in the pavilion in the garden, and when Li Su followed the palace maid to the pavilion, he finally saw Concubine Yang sitting on the rocking chair, stroking her high bulging lower abdomen with a happy face, still holding the book in her hand, just talking to the baby in her belly while reading, looking like a standard mother.

However, when Concubine Yang saw Li Su, her face did not show the joy of reuniting with her son after a long absence, but her face turned pale, and she scolded Li Su angrily: "Stinky boy, don't let me roll over!" ”
