As soon as he came to Huaixi, Li Yu publicly declared on many occasions large and small that he was not here to fight, and that he just wanted to defend his own territory. There are many spies in Huaixi, these words are naturally easy to enter Wu Yuanji's ears, the cowardice and incompetence of the Tang Army on the West Road, under the toss of Li Yu's two predecessors, has been deeply imprinted in Wu Yuanji's mind, Li Yu's initiative to show weakness, just confirmed this judgment, Wu Yuanji is finally convinced, Li Yu and his predecessor are no different. From this point of view, the "wonderful" performances of Li Yu's two predecessors are not all useless, at least they helped Li Yu confuse Wu Yuanji. In fact, this is also in line with the materialist dialectic, where everything has advantages and disadvantages, and in the same way, everything has disadvantages and advantages. Of course, just like this, it can only make Wu Yuanji careless, but it is not enough for him to transfer the main force, but the person who volunteered to help and acted in friendship came, and this person was none other than Li Guangyan from Nanlu.

Li Guangyan, as always, tirelessly ravaged Wu Yuanji's fragile nerves, the south road is precarious, the west road is, the dawn here is quiet, what to do? Transfer the main force of the West Road to the South Road, and fight to the death with that damn Li Guangyan, the tiger is not powerful, you take our Huaixi as a sick cat! But Wu Yuanji forgot that there is often a huge crisis in the silence, as the saying goes, a dog that can bite people doesn't bark, it's not good, this metaphor is not very good, people who can bite dogs? It's not good, forget it, don't talk about it, you know anyway. In short, Wu Yuanji made a mistake, a fatal mistake, he regarded Li Guangyan as the only protagonist, and Li Yu as a trickster, so he was wrong, and the mistake was outrageous, because, the generals of the Tang Army had at least two protagonists, one played hard at the front desk, which attracted Wu Yuanji's attention, and the other hid behind the scenes, hiding in a corner that Wu Yuanji turned a blind eye to, planning a more exciting plot, these two protagonists are of course Li Guangyan and Li Yu. Of course, at the right time, Li Yu will walk to the front desk and give Wu Yuanji a big surprise, and by that time, everything will be settled.

Next, Li Yu will also face a problem, a thorny problem, how to confirm that Wu Yuanji has transferred the main force of the West Road? You must know that this is a highly military secret, and although Wu Yuanji is not smart, he is not a complete fool, and he is not stupid enough to tell his military secrets to his enemies. Although Li Yu is smart enough, he is not Sun Wukong, there is no way to get into Wu Yuanji's stomach, and there is no way to become a roundworm in Wu Yuanji's stomach, so, in the Tang Dynasty, where there were no high-tech reconnaissance methods, what did Li Yu rely on to obtain accurate information? Is it a knight who flies off the wall, or a spy who infiltrates the enemy? No, neither, even if these people get information, they must be half-clawed, only a few words, and it is difficult to make an accurate judgment on the overall situation. From this point of view, wouldn't it be very difficult for Li Yu to get such a high level of military secrets? But this seemingly difficult question is not a problem at all with Li Yu, because he has a channel to obtain enough information. This is a channel that is not uncommon to say, but few people seriously dig it, demoting the general. Although Wu Yuanji covered his mouth, he couldn't control the tongues of others, these others were actually no one else, they were his subordinates, of course, former subordinates.

Although, for Li Yu, the war has not yet begun, he already has a wealth of intelligence resources, tongues. However, Li Yu also has a ability, a skill that others can't reach, as long as it is a tongue, Li Yu has a way to make them speak, open their mouths willingly, open their mouths with gratitude, and open their mouths in the form of pouring beans on bamboo tubes. Therefore, from these tongues, Li Yu obtained a lot of military secrets about Huaixi, and it can be said that Huaixi has basically no secrets to speak of in front of Li Yu. Needless to say, those small fish and shrimp don't need to be said, the key is that this time, Li Yu also caught a big fish, to a certain extent, it is precisely because of this big fish that there will be one bigger fish after another falling into Li Yu's net, among them, the biggest fish is, of course, Wu Yuanji, the envoy of Huaixi Jiedu.

The rebel general Ding Shiliang is a person who can't be idle, and Ding Shiliang, who can't be idle, often comes out to wander, wanders around, and sneaks to the Tang army station, looking left and right, no one pays attention, then kill someone, set fire or something, and by the way, get some loot, and return with a full load leisurely. Tang Jun couldn't hide and hide, he couldn't fight and couldn't fight, he could only blow his beard angrily and stare at him, and he didn't have any tricks at all. The soft persimmon was easy to pinch, and Ding Shiliang was addicted to pinching and began to enjoy it. He frequently went to the neighbors' houses around him, of course, the kind that did not greet the owner, not only did he not say hello, but he also took good things when he saw them, not even an IOU, and did not treat himself as an outsider. The nearby Tang army was overwhelmed and miserable.

Ding Shiliang, who is delicious and doesn't pick up chopsticks, obviously forgot a common saying, how can you stand by the river without getting your shoes wet? What's more, at this time, the commander of the Tang Army on the West Road has become Li Yu! So, this time, Ding Shiliang's shoes were finally wet, and they were wet thoroughly, because not only the shoes were wet, but even his body was lost. As a result, Ding Shiliang was honored to become the first big fish in Li Yu's net.

Staring at Ding Shiliang, who was tied up with five flowers, the eyes of the Tang army soldiers seemed to be about to erupt fire, they held the hilt of the sword one by one, and just waited for Li Yu to give an order, they chopped the person in front of them into meat puree, made a bowl of miscellaneous fish soup, and relieved their hunger and anger, how cool it was!

Since he became a prisoner of the Tang Army, Ding Shiliang knew that he would definitely not end well, it was useless to kowtow and beg for mercy, so he simply was more generous, smiling, and killed.

But they were wrong, whether it was the Tang Army soldiers or Ding Shiliang, they were all wrong. Li Yu doesn't want to drink miscellaneous fish soup, he just wants to catch more and bigger fish, what fish eat what kind of bait, he doesn't know very well, and those people under him don't know, this needs the help of others, Ding Shiliang is a good candidate, so Ding Shiliang can't die, not only can't die, but also stay as a guest.

From a death row prisoner who was slaughtered by others, he suddenly became a courteous guest, and Ding Shiliang, who was bound to die, suddenly became a little confused, not that I didn't understand, but that the world was changing too fast. After a short period of confusion, what came to Ding Shi's conscience was gratitude and guilt, to be able to follow a leader like Li Yu, even if he died a thousand or ten thousand times, he would not lose; Looking back and thinking about the former boss, Wu Yuanji, the envoy of Huaixi Jiedu, what kind of thing is that, why did he follow his ass in a daze for so many years, ashamed, ashamed of himself. Ding Shiliang, who came to his senses, immediately expressed his willingness to follow Li Yu and never give up. He didn't just pay lip service, he took immediate action. He told Li Yu that Wu Xiulin, who guarded the Wencheng Gate, was a powerful arm of Wu Yuanji, and Chen Guangqia was the brain of this arm, as long as Chen Guangqia was caught, it would not be difficult for Wu Xiulin to surrender or capture. Li Yu didn't think about it, and immediately sent him to capture Chen Guangqia alive.

Soon, Chen Guangqia became the second big fish in Li Yu's net, and Chen Guangqia sent a letter of persuasion to let Li Yu catch the third big fish, Wu Xiulin. Soon, Wu Xiulin was moved by Li Yu's courtesy, and took the initiative to come to offer advice, he told Li Yu: Li Hu, the commander of the cavalry, is the pillar of Wu Yuanji, and if Li Hu is captured, Wu Yuanji will basically be useless. Soon, Li Hu became the fourth big fish in Li Hu's net, compared to the three people in front of him, Li Hu was even more unpopular with the Tang army soldiers, because this person was too brave, and the Tang army soldiers who died under him were not a thousand, but eight hundred. Therefore, after capturing Li Hu alive, the soldiers of the Tang Army could no longer hold their breath, and they demanded that Li Hu be killed to avenge the dead soldiers. But Li Yu told them: Killing Li Hu can only vent his anger for a while, but it will not benefit the overall situation; On the contrary, if Li Hu can be recruited, he can increase the power to destroy Wu Yuanji.

On the issue of Li Hu, Li Yu showed his extraordinary courage, and in the face of the suspicious eyes of the soldiers of the three armies, he released Li Hu, and not only that, Li Yu also allowed him to recruit death squads on his own. What's more, Li Yu stayed in the secret room with Li Hu all day long, and another general, Li Zhongyi, to plan a big plan together. Someone warned that those two people are both generals, people's hearts are unpredictable, and the sea is difficult to measure, you had better pay attention to it, don't fall for them, and then it will be too late to regret it. Li Yu smiled, still the same as me. The coach is so heartfelt, Li Hu and Li Zhongyi are naturally grateful and swear allegiance.

In May of the twelfth year of Yuanhe, after repeated arguments with Li Hu and others, Li Yu formulated a bold plan to raid! Raid on the rebels' lair, Caizhou. Li Yu also asked Li Hu to preside over the recruitment of 3,000 death squads, known as "sudden generals", with Li Hu and Li Zhongyi as the lead, and Li Yu personally pressed the formation. It seems that this is an unbelievable adventure, with only 3,000 people, going deep into the hinterland of the rebels, and if you don't make trouble, you will be dumplings by the rebels. But Li Yu was sure that this raid would be successful, because he had obtained accurate information, and Caizhou today was basically equivalent to an empty city.

Everything was ready, God seemed to have mercy, and he couldn't bear to let Wu Yuanji lose Qingqing's life so quickly. So it rained, and it rained intermittently, from May to July, and the raid had to be postponed again and again.

Finally, the rain stopped, and the problem came again. The officers and men of the Tang Army, who were originally suspicious of Li Hu, suddenly found evidence, and they ran to Li Yu in a crowd, saying that this continuous heavy rain was a warning from heaven to us, and Li Hu was not credible and could not be used, so he should be killed. Facing the agitated subordinates, Li Yu knew that if he didn't handle it properly, it might cause a riot. As a last resort, Li Yu had no choice but to play a trick, he told his subordinates that since this is the case, only let Chang'an and let the Son of Heaven decide Li Hu's life and death, so that we have nothing to say to each other, and the soldiers agreed. In this way, Li Hu was escorted to Chang'an, but he did not bring any torture instruments. Li Yu believed that Li Chun, the wise and martial emperor, should understand what he meant. However, for the sake of insurance, Li Yu still took another step and sent it to Chang'an as soon as possible. A few months later, Li Hu returned to the front line with the holy decree of Chang'an, still his tooth general, and still Li Yu's think tank.

With such a toss, the time has come to October of the twelfth year of Yuanhe, and Wu Yuanji has lived for five more months! This time, Li Yu was determined not to wait any longer and set off! Three thousand soldiers embarked on a long road of death, and of course, the person who was going to die was Wu Yuanji.
