The reason why Li Shimin hurriedly called Li Su to the palace was because the results of the investigation into the assassination of Li Su finally came out, although there was no definite evidence, but the information fed back from all sides, as well as various signs of several suspects before the incident, showed that the mastermind behind the assassination of Li Su was Fan Yang Lu.

And they did this, as Li Shimin analyzed at the beginning, it was through this incident that Li Su fell into the battle for the throne and could not get out, and then they took the opportunity to suppress industry and commerce, but unfortunately Li Su was not fooled, so that all their calculations fell into vain.

Although all kinds of signs indicate that this matter was done by Fan Yang Lu's family, even if Li Shimin launched his full strength, he did not get any substantive evidence, which shows that the other party handled it very cleanly and did not leave any handle at all, so even if he knew that it was Fan Yang Lu's family, he had no way to deal with them, not even Li Shimin, the emperor. After all, the Tang Dynasty is not the whip dynasty of later generations, because a few words can raid the family and wipe out the clan, the emperor of the Tang Dynasty wants to kill a courtier, he must have a heinous charge, and at the same time, he must be able to come up with reliable evidence, let alone want to deal with a family that has been entrenched for nearly a thousand years.

After returning to the palace, Li Su immediately told Wang An about it, and then asked angrily: "Wang Fu, can you do anything so that I can give Lu a little color to see?" ”

Wang An has been officially appointed as the prince of the Qi Palace, and after these days of recuperation, the embarrassment and haggard that Li Su had when he first saw him can no longer be seen, replaced by a kind of elegance and wisdom. I saw that after he heard Li Su's words, he laughed and said, "Your Highness wants to take revenge on the Lu family? In fact, speaking of which, in addition to wanting His Highness to be caught in the battle for the throne of the prince last time, it can also be regarded as the revenge of the Fan Yang Lu clan against Your Highness? ”

"Revenge on me?" Li Su was stunned for a moment after hearing this, and didn't understand what Wang An meant in his words?

"Huh. Your Highness may not know yet. In addition to occupying a vast amount of land, the Fanyang Lu clan was almost entirely controlled by them in the tea making industry of the Tang Dynasty back then, but later His Royal Highness came up with the method of roasting tea. As a result, the tea cakes made by the Lu family were not marketable, and the clan also lost a source of income, although they later bought the patent for the use of roasted tea. But it was too late, the tea market had already been carved up by His Highness and others, and the profits that the Fan Yang Lu clan had now made from the tea industry were almost nothing compared to before. Wang An said with a smile. As far as he knew, in addition to the income from the land, the Fanyang Lu clan only had two pillar industries, and tea making was one of them, but unfortunately it was unintentionally abolished by Li Su.

Li Su was also stunned after hearing this, but he didn't expect that he would provoke the other party first. But he was angry, and he couldn't care about these at all, and said angrily: "Even if I provoke them first." Technology is inferior to people. Naturally, they will be eliminated, and they don't want to solve the dilemma fundamentally. But they came up with this kind of yin trick calculation king, in vain their five surnames and seven hopes are also known as poetry and book heirlooms, I think they should be conspiracy heirlooms! ”

Speaking of which, Li Su remembered that when he was assassinated, he scared Wen Xin and Xijun a lot, especially when Xijun was already pregnant, and he was frightened by this, and he didn't know if it would have any impact on the development of the fetus? Thinking of this, he was even more angry, and slapped the table fiercely and said, "Wang Fu, I can't swallow this breath no matter what, what can you do to take revenge on the Lu family?" ”

"Hehe, others may not be able to meet the Lu clan, but for His Highness, it is extremely simple!" Wang An saw that Li Su had such a big temper, but he still said with a smile, "There are three main industries of the Fanyang Lu family, not to mention the land, the tea industry has been inadvertently abolished by His Royal Highness, and in the end, there is only one linen industry left, hearing this name, His Royal Highness must have known what to do, right?" ”

Sure enough, as Wang An expected, as soon as Li Su heard that Fan Yang Lu's third pillar industry turned out to be linen, his eyes immediately lit up, and the anger on his face disappeared, but turned into an extremely sinister smile, and at the same time muttered to himself: "Hehe, there is a way in heaven that you don't go, and there is no door in hell for you to break in, what are you doing badly, but you are making linen, now Lao Tzu will see how you die!" ”

Before the large-scale promotion of cotton cloth, there were three main materials for the ancients to make clothes, fur, silk, and linen, but whether it was fur or silk, its output could not be compared with linen, and linen was also the cheapest of the three, so linen has been the main clothing material for the middle and lower class people for thousands of years.

Linen cloth is mainly made of various hemp-producing plants, and then spun into fabrics after being soaked in hemp, but at this time the linen cloth is very unstrong, and very rough, and it is worn on the body like a needle prick. In order to solve this problem, it is necessary to sizing and pounding clothes, so that the linen cloth is suitable for making clothes to wear on the body, and it is strong and wear-resistant.

However, compared with the production of troublesome, and the appearance of rough, stiff linen, Li Su is now building a textile factory, the production is more excellent cotton cloth, compared with the shortcomings of linen, cotton cloth can be described as a lot of advantages, not only soft texture, but also strong and durable, some cheesecloth made of clothes, enough for a person to wear for more than ten years can not be worn. The weaving of cotton is not as time-consuming and laborious as linen, and the cloth that can be woven into cotton is also diverse, from coarse to fine, and the texture is fine and easy to color, so both the appearance and practicality are much stronger than linen.

In addition, Li Su also knows one thing, since the Song Dynasty began to promote cotton cloth, linen cloth has slowly withdrawn from the mainstream of fabrics, few people wear linen clothes anymore, at most can only be made into a burlap bag for things, and the sack that has been rare in later generations is actually a kind of burlap bag.

So no matter from which point of view, cotton cloth instead of linen cloth is definitely the trend of the times, now Li Su partners with the upstarts and major businessmen in Chang'an City, is building textile factories everywhere, in order to make huge profits on cotton cloth, but Li Su has never thought that Fan Yang Lu's is the country's largest linen cloth producer, it can really be said that the road is narrow!

However, before Li Su was happy for too long, he heard Wang An speak again: "Your Highness, the cotton textile factory you are building can be described as a lifeline for the linen industry, if the Fan Yang Lu clan loses the income of the pillar of linen again, the clan will only rely on land and some other small industries, and it will definitely not be able to support it. ”

Since he had Wang An's think tank, Li Su has been a lot lazy, he is lazy to use his brain on general questions, and it is good to ask him directly if there is anything, so he immediately said: "Wang Fu, please speak!" ”

"Well, in fact, it's not a big problem, but the time for the promotion of cotton crops is still too short, subject to the yield of cotton, we can only build textile factories in a few areas where cotton is planted more, with the amount of cotton cloth produced by these factories, it is definitely impossible to completely eliminate linen on the market, so the key to cotton cloth is not in the textile mill, but in the output of cotton." Wang An summed up his thoughts for a moment before he spoke.

Li Su also nodded after listening, this is a problem, cotton production is not a moment and a half will be able to go up, after all, even if the crop is good, it will take a certain amount of time to promote, not to mention that cotton is a cash crop, can not be used as food to eat, many farmers even if they plant, but only a small amount of planting, most of the land still has to grow edible wheat, rice and other crops, so the output of cotton is growing fast, but it is still limited.

The yield of cotton could not go up in a short time, and Li Su's method of using cotton to retaliate against Fan Yang Lu's family could not see the effect for a while, which made Li Su, who was eager for revenge, feel a little impatient, and asked Wang An for other possible ways to retaliate, but the effect was not ideal. Li Su doesn't want to be able to uproot the other party all at once, but at least let them break their muscles and bones, or even collapse, so as to deter those big families and let them see what will happen to him Li Su!

However, just when Li Su had a big headache about this, there was a news from the court that shocked his spirits, and this news was still related to the Turks.

It turned out that in the fourth year of Zhenguan, the Tang Dynasty sent troops to destroy the Eastern Turks, not only pacified the north in one fell swoop, but also shocked the countries of the Western Regions, coupled with the civil strife of the Western Turks at that time, the control of the Western Regions weakened, so many countries in the Western Regions raised cities to surrender, so that the Central Plains Dynasty once again opened the door to the Western Regions after the Han Dynasty.

At the same time, the civil strife in the Western Turks intensified, and the Tang Dynasty saw the opportunity to intervene in this civil strife in the sixth year of Zhenguan, and set up its own agents in the Western Turks, hoping to control the entire Western Turks through the policy of restraint. However, it is a pity that the Tang Dynasty chose the wrong agent, and the son of a khan who fled from the Eastern Turks to the Western Turks, a guy named Desire Gushe, began to rise, and defeated the Ashina supported by the Tang Dynasty against Russia, and even had the tendency to unify the Western Turks.

If it was just like this, Datang would not have made a big move, but this guy who wanted to set up Gushe was carried away by the victory, and after controlling Gaochang, he laid the gateway between Datang and the Western Regions, and blocked the connection between Datang and the Western Regions, that is, cut off the land Silk Road that Datang attaches great importance to.

As a result, the Western Turks and Gaochang Ke aroused public anger, and the Tang Dynasty was noisy, most of them demanded that the imperial court send troops to reopen the connection with the Western Regions and restore the smooth flow of the Silk Road.

However, compared with the excitement of most courtiers, several important civil and military ministers such as Fang Xuanling and Li Jing expressed their opposition, and even Li Shimin, who has always been belligerent, wavered on this matter, and did not know how to decide?
