Li Siye gave an order, Tian Zhen held the Mo knife in his hand to drive away the Shuofang army and Youzhou soldiers who surrendered and pushed the ladder car to attack the city, Yan Xiaosi ordered the artillery battalion to ignite the Xuanwu cannon and bombard the city to cover the siege of the surrendering army.

Guo Ziyi quickly ran to the city and glared at the two eunuchs in disappointment. They are clever and ignore their own prohibitions, which is equivalent to exposing all the situation in the customs to the other party.

Guo Xi calmly commanded the crossbowmen on the head of the city to shoot arrows, and ordered people to throw stones downward to smash, and the wood and cannon stones were used in turn, the two sides fought for half a day at the head of the city, leaving nearly a thousand corpses at the root of the city wall, until the evening Li Siye ordered Mingjin to collect the troops and withdraw to the Lingbao camp.

Li Siye sat alone in silence in the big tent in the camp, and Duan Xiushi, Tian Zhen, Bai Xiaode and other generals were waiting outside the tent. In fact, the anger in his heart had already been resisted, and he was carefully thinking about the current battle situation and how to find changes in the stalemate.

When everyone was worried about the leader's mood, Xu Bin lifted the curtain and entered the tent, as a close confidant who had followed him consistently for many years, he believed that the lord was not a person who would be easily swayed by emotions.

"Don't be angry, the court's move is to disturb our minds, and now the plan to conquer Tongguan as soon as possible is the top priority."

"I know." Li Siye turned his head to look at him and said, "Only incompetent people can be angry. ”

"Now the people guarding Tongguan have changed, but there is still a big flag of Li Guangbi on the head of the city. Guo Ziyi didn't expect that Yu Chaoen and other eunuchs would reveal his bottom. ”

Xu Bin seemed to have an understanding and asked, "The imperial court has changed Guo Ziyi, will there be a change in strategy?" ”

"Of course there will be changes, Guo Ziyi thinks carefully, no matter how big or small, what we can think of, he will definitely be able to think of. He will definitely make the imperial court send someone to recruit Shi Siming again, and he will also order Nanyang Lujiong to go north, and even the Hedong army will gather in the Puzhou area, and the road from Pujin to Guanzhong will be difficult."

Xu Bin said to him: "General Cui Qianyou once broke through Tongguan and fought in Hedong, why didn't the lord call him to ask about countermeasures?" ”

"Cui Qianyou?"

Since An Qingxu surrendered to him in the Battle of Yecheng, the solemn and noble Cui Qianyou and others under his command have been shelved by Li Siye, and now if they can employ people in an eclectic way, they can ask him for countermeasures.

"Okay, let's invite General Cui over."

Xu Bin forked his hand and withdrew from the big tent, and after a while, Cui Qianyou walked in, knelt down on one knee in front of him and forked his hands: "Humble Cui Qianyou see the lord." ”

"Hurry up, please." Li Siye leaned over to help him up, and asked with a pleasant face: "Our army was blocked in Tongguan, and I asked the general for advice, how to break the enemy and enter the pass?" ”

Cui Qianyou pondered for a moment, crossed his hands and said: "Tongguan is not better than other places, but the Tang Dynasty and the emperor's life, the pressure on the general guarding the pass can be imagined, the lord should know that the emperor is extremely suspicious of the general, why not the lord to use a divisive measure." ”

Li Siye shook his head and smiled: "How could they trip over the same thing twice, besides, the discord scheme may be effective for Li Guangbi, but Guo Ziyi ...... This man has always been foolish and loyal, and he has tied his net worth and life to the emperor, even if the court digs up his ancestral grave, he will not change his ways. ”

Cui Qianyou followed his words and said: "The lord is right, there are many loyal generals to the emperor, but there are very few people who really believe in the emperor. ”

After he looked up and saw Li Siye's gradually clear gaze, he hurriedly lowered his head and said, "This is a little stupid opinion of the humble position, just for your reference. ”

Li Siye was insightful in his heart, nodded and said to Xu Bin on the side: "Call Cen Shen, Yan Zhuang, Gao Shang, Duan Xiushi, Yan Xiaosi, Bai Xiaode, and Tian Zhen in." ”

The generals and staff members who entered the tent sat on both sides, and his eyes suddenly opened up and said: "General Cui's words just now made me suddenly clear, I naturally can't let the imperial court completely alienate Guo Ziyi, but I can let them add to the rift and play a set of combination punches against their actions." If the imperial court wants to resolve the Tongguan crisis, it is inevitable to send an envoy to Youzhou to persuade Shi Siming to surrender, and we can contact Shi Siming first. Who wants to go? ”

After he said this, he subconsciously turned his gaze to Yan Zhuang who was sitting on the right side, and Cen Shen took the initiative to stand up and said, "Lord, I am willing to go to Youzhou again to persuade Shi Siming to unite with our army." ”

Yan Zhuang seemed to have a sense, and he also stood up and crossed his hands and said: "I am also willing to be an envoy and persuade Shi Siming to advance and retreat together with a three-inch tongue." ”

"Okay," Li Siye said approvingly: "I believe the two, although there are difficulties and dangers in this trip, we can put forward rich conditions to Shi Siming, Hedong has always been the weakness of the land of Youyan, only by controlling Hedong, Shi Siming can safely occupy the north, as long as he is willing to cooperate, I can let Xiangzhou, Weizhou and other places, which can make it convenient for him to enter Hedong from the Jingjingkou and Niangzi Pass in Taihang Mountain, I can not only contain the defenders in Tongguan, but also induce the main force of the Hedong Army to go south to Puzhou to defend the Yellow River crossing, isn't this his God-given opportunity?" ”

The two of them crossed their hands in unison and said, "What the lord said is very true, we will definitely bring your words." ”

He said to Xu Bin again: "Brother Xu, you go down to Nanyang for me to see Lu Jiong, he used to be my old subordinate, I heard that his army was the first to retreat after hearing the defeat of Yecheng, robbing the people in the process of fleeing south, burning and killing and plundering, this is his heart disease, you use this as a breakthrough to persuade him not to go north, you can forge two letters in advance to impeach him." ”

Xu Bin replied with his crossed hands: "Please rest assured, I will definitely do this." ”

Li Siye rubbed his hands again and said: "It's time to deal with Guo Ziyi next, Guo's take advantage of Tongguan and control the 100,000 people in Guanzhong, such as the Longxiang Army and the Longwu Army, although they have never participated in the war, but the equipment and armor are always the best, if he sticks to it for three or four months, our army will be exhausted after all." Just now Cui Qianyou said very well, when the enemy is in danger, the generals of the imperial court, the eunuchs and the emperor can all be twisted into a rope, but if the alarm is lifted, they will soon fall into a fight with each other. Our first step is to use a divisive strategy to test how sensitive the imperial court's attitude towards the generals is, and affect the morale of the Tongguan army. The second step was to submit a surrender document in the name of surrender and negotiate with the imperial court to stabilize Guo Ziyi. ”

"Only part of the troops were left in front of Tongguan, and after Xu Bin solemnly persuaded Shi Siming to attack Hedong, the Flying Tiger Cavalry and the Han Navy entered Shangdang County in Hedong from Hukou Guguan Wueryu. I want to see if Deng Jingshan, the envoy of Hedong Jiedu, can take care of Taiyuan in the clouds, or take care of Shangdang Puzhou. ”

It is impossible to directly carry out a discordant plan against Guo Ziyi, the emperor has made careful precautions in advance, Guo Ziyi took the initiative to hand over the whole family to Li Fuguo to monitor Chang'an, this similar move to carry the coffin to take office is enough to make Li Heng double his trust. But Guo Ziyi's ability to gain trust does not mean that others can also gain trust, and there is a shortcoming among the generals who retreated to Tongguan, that is, Feng Changqing, who succeeded as the envoy of Anxi Jiedu.

Li Siye felt very sorry for Feng Changqing, since he rode into Weizhou to seize power, Tian Zhen and Li Chongyun took away half of the army, but Feng Changqing insisted on returning to the imperial court.

This is a difficult task for people to have their own ambitions, and he did not blame Feng Changqing for his disloyalty. However, Feng Changqing's loyal actions did not move the imperial court, but he has been given a cold reception because of his former identity. The other Jiedu envoys had their own places to settle down, but the Anxi army led by him could only be attached to the Shuofang army.

Now in order to capture Tongguan and disturb the hearts of the enemy's army, he had to start with this old subordinate first and use his blood to expose the essence of the imperial court.
