Yandu, the prince's mansion.

At this time, Yan Dan and Cheng Yu sat opposite each other, their faces so gloomy that water almost dripped out: "Sir, Juyongguan, lost." Yan Dan clenched his fists tightly and said with trembling all over. The so-called plan cannot keep up with the changes is what it means. Juyongguan, who was originally the most unlikely to be lost, was lost overnight. Xiahou Qingyi, a veteran who had been fighting on the battlefield for a long time, did not hold on for a night. This is incredible! Cheng Yu's face was calm and he did not speak. Cheng Yu obviously had expected this situation, and had even quietly arranged a backhand that could turn the tables.

Yan Dan didn't want to know how this level was lost. He just wanted to get everything back on track now. "Your Highness, the prince, I have a plan to withdraw from the Zhao army." Yan Dan hurriedly said, "Sir, please speak." Cheng Yu hesitated for a moment before speaking, "In fact, Yu had already imagined the possibility of losing Juyongguan before, so he specially set up a blood-killing snow formation in Juyongguan."

Hearing this, Yan Dan frowned and said, "Why did sir set up such a vicious formation?" Cheng Yu looked at the gray sky and said, "Just in case, I didn't expect it to come in handy. Yu once imagined that if Zhao Guozhen sent someone to solve the problem, who would be the most likely to send. In the end, Yu thought about it, only the champion, Hou Mu Huaiyuan."

Hearing this, Yan Dan said in confusion: "How can you see it?" Cheng Yu explained: "Send troops to get the pass. This is to force me to take the army to take dangerous moves, forcing me to take the troops back to defense. When the war between the two sides begins, I, Yan, will be in danger. In the Yan Kingdom, there are only four people who are capable of capturing Hangu Pass, one is Le Yi, the second is Lian Po, the third is Li Mu, and the fourth is Mu Huaiyuan." When Cheng Yu sighed, the many good generals in Zhao State were really enviable.

Then Cheng Yu continued to analyze: "First of all, Le Yi and Lian Po must be ruled out. Le Yi was the pillar of our Yan State before, and His Royal Highness the Crown Prince should know." Hearing this, Yan Dan nodded with a serious expression. Le Yi led his army to 70 cities in Qi State for half a year, and the "East Emperor" was in a slump and has not recovered yet. It is not an exaggeration to say that he is using troops as good as a god.

"It is Le Yi's reputation that King Zhao will definitely send Le Yi to Luqiu to intimidate Qi, so that he will not dare to invade. If Lian Po leads his army to attack, he will inevitably go to the front line to increase the morale of the Zhao army. It is unlikely that he will lead the army to attack the city." "So why don't sir consider Pang Xian?" Yan Dan said in confusion.

Cheng Yu said, "Although Pang Qing likes to send out surprise troops, he is old and will not easily attack Jiayuguan, which is so tall that he can easily attack Jiayuguan. You must know that if one blow is not done, this trick to remove firewood from the cauldron will definitely not work." Yan Dan nodded with approval.

"But Mu Huaiyuan is different. He is young and powerful, wise and brave, and beat Qin general Wang Jian to pieces, and even his son died at his hands. The reputation of capturing a tiger with bare hands has spread throughout the country, and is known as the most powerful general in the history of Zhao. Such a person is really capable, and he is young and has the spirit of adventure."

"Mu Huaiyuan is a man who loves money but takes it well, while raising singers but is not beautiful, and self-discipline makes people feel incredible. Such a person must have lofty ambitions in his heart, and he must also be clear about the risks he has to take over the great achievements made by Juyongguan. In order to prevent the king from being afraid of, self-deprecating is inevitable. The best and most effective way to deal with self-deprecating is to scramble the city."

"The blood-killing snow formation is the condition that there is enough blood and resentment. Blood can be collected when you attack the city. As for resentment, 300,000 people in Juyongguan were robbed by Mu Huaiyuan. How could their resentment be not strong?"

After hearing Cheng Yu's explanation, Yan Dan continued to ask: "Sir, although the probability of Lian Po's attack on the key points is small, it is also possible. If it were Lian Po this time..." "There is no difference in the result. Have Your Highness heard the widely circulated poem half a year ago: You can't learn from Lian Po, and you can run wildly with a knife in Qi Chuye, and slaughter Yang Jin and change to purple robe. Lian Po has always spoiled his soldiers. After attacking Juyong Pass, he will not stop his subordinates from raging."

Hearing this, Yan Dan was silent for a while and said, "Sir, wise, with the help of Mr. Dan, how can you worry about not having a great cause!" Cheng Yu shook his head and said, "The snow formation was set up in advance, just to be assured that if you kill a thousand enemies, you will lose 800 yourself. If you launch such a fierce formation, even if you can force Mu Huaiyuan to retreat, then the 300,000 people in the city will not be able to escape the disaster."

The Blood Killing Snow Formation, praying to the sky through a certain number of "sacrifices", can cause snowfall that lasts for several months. The more people die in the snow, the greater the power of the formation. If Mu Huaiyuan can see through this terrifying formation, then he must choose to withdraw his troops. If he does not see this large formation in time, hehe, it will be difficult to run away at that time.

The formation is used to forcibly change the time of heaven and earth, and to use the power of heaven and earth to defend the enemy, making it difficult for the enemy to find that he is hit. This is the horror of the counselors of one of the magic lines. Although they do not have the ability to fight melee, they have to a certain extent the supreme power that surpasses everything.

There are many wise men in the world who can expect Juyongguan to be lost. However, there are very few people who can launch this vicious formation at the cost of 300,000 people, and kill Mu Huaiyuan, so few that the whole world has only the number of ungrown strategists. It can only be said that he is worthy of Cheng Yu, and he is one of the few top wise men with the title of "poison warrior".

From the beginning of planning and layout to the current situation of not being able to launch a drug plan to kill Mu Huaiyuan in the face of danger, Cheng Yu's psychology has not been turbulent in the whole process, which shows that this person is a werewolf.

Hearing this, Yan Dan closed his eyes and took a deep breath and said, "For the sake of the foundation of the Great Yan, appropriate sacrifice is necessary. Just follow the plan of the teacher." Hearing this, Cheng Yu lowered his head and said, "I will accept the order."

At this time, Mu Huaiyuan, who had just occupied Juyong Pass, also began to issue military orders. First, his vanguard cavalry quickly rushed to the Yinrao battlefield to support Lian Po. Now the patrol cavalry of Yan State has arrived at the front line battlefield. In order to prevent accidents, the cavalry must be sent in advance.

Then he ordered the entire army to temporarily station in Shanhaiguan and wait for the next clear order. However, Mu Huaiyuan did not expect that once he stayed in Juyongguan, he had been living for a long time. He had already fallen into Cheng Yu's trap without realizing it. However, due to the climate of Yan State, this trap was also very difficult to detect.

At this time, the Jianghu Sect at the foot of Changbai Mountain in Yandi also received a secret letter. After a while, the disciples in the city came out in full bloom, which looked very spectacular.
