At this juncture, the fine work sent by Zhang Liao arrived in time, but it was not easy for them to find out the situation at once, because it was not easy to understand the situation underground in a huge place, which required continuous investigation to find out Cao Ren's specific location, but fortunately, before departure, Guan Yu made an instruction to Zhang Liao after some calculations: According to the time, Cao Ren's excavation position should be about 50 meters away from the Tiger Prison Pass tonight, so these people do not need to go to a distance to investigate, You only need to survey near Tiger Pass, and it's relatively safe

Zhang Liao's subordinates soon found out Cao Ren's movements after investigation, at this time Cao Ren was only a few meters away from the Tiger Prison Pass, the situation was extremely critical, these people found out the situation and quickly climbed the Tiger Prison Pass to Zhang Liao to report, Zhang Liao was shocked when he heard it, and hurriedly found Guan Yu to explain the situation to Guan Yu, Zhang Liao hurriedly said: "The general's situation is extremely critical, what should we do?" ”

"That's the best, it looks like tonight is the time for them to lose!" Guan Yu said after hearing this.

Guan Yu's words made Zhang Liao a little confused, only to see him ask in surprise: "General, the more I listen, the more confused I become, the eyebrows are burning now, how can it be a big defeat for others?" ”

"Hehe, don't worry, just wait and watch the show! They will definitely be able to open the tunnel tonight, you have to send people to continue to track and monitor, to find out in time where they hit the location of the pass in the Tiger Prison Pass, and then send troops to surround the pass, as long as all the soldiers who rushed up are killed on the spot, you only need to prepare archers, so as to avoid casualties! That's your mission tonight! Be sure to do it cleanly! Guan Yu instructed Zhang Liao.

Zhang Liao took the order and left, and he quickly gathered his subordinates. Prepared bows and arrows to the south side of the Tiger Prison Pass to get ready, on the other hand, Zhang Liao continued to send people to investigate Cao Ren's situation, and everything was done according to what Guan Yu said.

Guan Yu made arrangements for Zhang Liao, and he quickly convened an emergency military meeting to gather all the generals from all walks of life, and Guan Yu said to the generals: "There is an important military briefing to urgently summon everyone tonight. The Cao Cao Department of the Kwantung Army is about to open up the tunnel from the south side of the Tiger Prison Pass to the pass! ”

"What? How is this possible, there has been no sign on the south side! Guo Yan was the first to be suspicious.

Guan Yu continued: "This matter is very secretive, and the tunnel will soon be opened to the Guannei!" ”

"So what do we do? Cloud Chief! Li Su asked.

Guan Yu continued: "I have already made arrangements for this matter, I believe that Zhang Liao can take on this important task to successfully block the enemy, I summoned everyone to come here not only for this matter, but tonight the Kwantung Army will have a big operation!" So we have to be prepared in all aspects, they are likely to attack the city, and now we need to send troops and horses from all over the city to defend the city to prevent the gap from being opened. I have carefully analyzed, the enemy must use the underground passage as a breakthrough, use our paralyzed thoughts to break into the pass and then open the city gate, welcome the army into the city, tonight the Kwantung Army will gather a large army to attack the city, I have arranged for Zhang Liao to investigate and plug the gap, the city gate should be arranged to be guarded by heavy troops, this matter is in charge of General Wenpin. In addition, the city should strengthen the reserve of various war preparation materials, and this matter is the responsibility of General Li Su and Li Yan. The city should also arrange heavy troops to guard, mainly on the south side and the front must be arranged archers and rolling wood and stones, but also arrange heavy troops, this matter is in charge of Guo Yan and Zhang Ji, the two generals, and I hope that all the generals will work together to fight the enemy! ”

"I have to report such a big matter to the lord!" Guo Yan said after hearing this.

Guan Yu said categorically: "The situation is extremely critical, it's too late." Gentlemen, hurry up and get ready! ”

"The stakes are high, what if something happens?" Guo Yan said angrily.

Guan Yu clapped his hand and said: "If something happens, I will bear it alone, and it has nothing to do with everyone, everyone just prepare to go!" ”

Guan Yu said that Guo Yan couldn't say anything, after all, Guan Yu presided over daily military work, and his rank was also above himself, as a soldier, he still understood the principle of obedience. At this time, Guan Yu also seemed very domineering, he said that he had a strong influence in the army, and he was Dong Zhuo's celebrity in front of Dong Zhuo, and there were many supporters among the generals in the army

The generals from all walks of life have been ordered to prepare, Guan Yu is responsible for the overall scheduling of the entire military operation, Guan Yu personally supervises the actions of the generals from all walks of life, and he tries his best to take care of every link.

The situation of the tiger prison was soon seen by Cao Ren's soldiers hiding in the woods, and soon the situation was reported to Cao Renyu, and Cao Ren decided after hearing this: "There are not so many of them, our only goal is to open the tunnel!" At this time, the tunnel has been opened to the city wall of the Tiger Prison Pass, and you can enter the pass after crossing the city wall, Cao Ren didn't care about anything else, the dawn of victory was in sight, and he was completely carried away by the victory.

Yuan Shao's army raised 100,000 troops and rushed to the direction of the Tiger Prison Pass again, and the situation on Cao Ren's side quickly spread to Cao Cao's side, Cao Cao said after hearing this: "Although the army kills under the Tiger Prison Pass, it won't take long for the city gate to open, and then let the troops rush into the city, and then the army will cover up and break the Tiger Prison!" ”

"Mengde is very good! Tell the order to go down and march the army to the Tiger Prison! Yuan Shao ordered.

In an instant, the Kwantung Army surged forward, more than ten people and horses flocked to the direction of the Tiger Pass, in front of a large number of cavalry troops, followed by the infantry, the cavalry and the infantry staggered, there is a large gap between the cavalry teams, the infantry can rush forward from the cavalry spacing, the Kwantung Army is also prepared with both hands, in case of accidents.

Cao Ren and the corporal quickly crossed the city wall and hit the city, Cao Ren asked the sergeant to open the opening from the place close to the city wall, here is a horn, Cao Ren thought that the god did not know the ghost, where did he know that the southern city defense at this time had already been surrounded by many archers, Zhang Liao learned that Cao Ren had dug into the pass, while sending someone to report to Guan Yu, while asking the archers to prepare.

Guan Yu heard that Cao Ren had opened up to the pass, so he arranged for Li Yan to hurriedly transfer sandbags to the tunnel, Li Yan received the order and quickly transferred the sandbags to the south side of the city defense, there were dozens of bags, one word open, Cao Ren opened the news of the pass and quickly reported to Yuan Shao, the leader of the Kwantung Army under the city, at this time Yuan Shao's army was all pressed to the Tiger Prison Pass, just waiting for the pass to be opened, and then attacked the city gate, but the scene on the Tiger Prison Pass was not as good as Cao Cao thought, and the gate was not only strengthened but also had a lot of manpower, It seemed that he had made full preparations, and an ominous feeling suddenly surged into Cao Cao's mind: Could it be that Guan Yu knew about the authentic matter? No! It shouldn't be, otherwise Guan Yu would definitely attack, but at this time, they had already reached the Guannei, and Guan Yu still didn't make a move, if Guan Yu didn't notice it, why did he send so many additional troops? However, Cao Cao was still careful, and he sent a fine work to tell Cao Ren to be more careful

Yuan Shao's army came to the city, Guan Yu hurriedly boarded the Tiger Prison Pass, everything really came as he imagined, it seems that his prediction was right, "the magic is one foot high and the road is one foot high" Cao Cao, you can't escape from the palm of my hand, Guan Yu thought about it and came to the Tiger Prison Pass, but saw that the pass was crowded with people, and the torches were overwhelming, Yuan Shao's actions were beyond his imagination, it seems that they still put all their hopes on the tunnel, but unfortunately their conspiracy was still seen through by me.

Guan Yu saw that a large number of people and horses of the Kwantung Army were killed, and knew that Yuan Shao was waiting for the opportunity, they definitely did not dare to attack the city rashly, Yuan Shao and Cao Cao came to the Tiger Prison Pass and waited for Cao Ren's news, the large team of men and horses piled up there and was indifferent, Guan Yu saw that Yuan Shao's army was arranged in front of the Tiger Prison Pass, and he couldn't help but be overjoyed, if the cavalry took the lead, it would be much more difficult to retreat from the obstacles encountered in front, and where would the large number of infantry in the back have their room for maneuver?

Guan Yu said that Guo Yan and Zhang Ji were guarding the city: "Prepare the rocket and prepare to shoot!" ”

The two of them ordered all the archers to step forward together, Li Su had already arranged thousands of rockets, Yuan Shao saw that the enemy troops on the pass were ready to release rockets, and hurriedly urged Cao Cao: "Why hasn't there been news from Meng De's side yet?" Guan Yu is about to release the arrow! ”

Seeing this, Cao Cao was shocked into a cold sweat, and cold sweat suddenly oozed from his forehead, and he said to Yuan Shao: "I'll go and see the situation in person!" With that, he slapped his horse and ran towards the south of the Tiger Prison.

The sergeants who Cao Ren urged to dig quickly opened a gap in the pass, and soon dug a hole in the southwest corner of the city wall on the south side of the Tiger Prison Pass, and the tunnel was opened, and Cao Ren's subordinates finally did not work in vain, and these soldiers were soon ready to expose the ground, but when they showed their heads from the tunnel, they were immediately stunned by the scene in front of them

But seeing that countless bows and arrows were aimed at their heads, shooting in the same direction, aiming at the same target, before they could speak, let alone act, ten thousand arrows were sent at the gap in unison, too late to resist, too late to dodge, the soldiers who exposed the ground were soon regarded as live targets, drowned under the rain of arrows.

The people who climbed up in the tunnel were all shot to death, Cao Ren was shocked when he learned it: he never thought that the customs were actually ready, they thought that the gods were unaware of the progress but unexpectedly all in the hands of others, Cao Ren didn't know how to do it for a while, just then Cao Cao arrived, Cao Ren reported the situation to Cao Cao, Cao Cao was stunned when he heard it, it seems that things are not good! Cao Ren said to Cao Cao: "My lord, what should we do?" (To be continued.) )
