Liu Ziqiu laughed and said: "That team is led by Liu himself"

Wen Hao hurriedly persuaded: "The lord must not"

Liu Ziqiu waved his hand nonchalantly and said: "Walking the drainage culvert is an adventure, Liu himself doesn't have to move forward bravely, no one is willing to compete for the first place, don't say it anymore, go separately and prepare to go."

The people did not dare to persuade them any more, so they had to disperse

……

Two days later, several white pigeons landed in the barracks from the sky, this is Liu Ziqiu's specially trained carrier pigeon, although there is no carrier pigeon in this era, but Liu Ziqiu, who was born in special forces, of course, knows the role of carrier pigeons, and also knows a little about some methods of cultivating and training carrier pigeons, but carrier pigeons are only suitable for use in the Central Plains, in the Mobei grassland, or eagle eagles, it is more convenient to use

Opportunities are always reserved for those who are prepared, when the first batch of caravans returned from the Western Regions last year, Liu Ziqiu sent spies to infiltrate them, these spies lurked in Chang'an and Luoyang, and there were their figures in the city and outside the city, while spying on intelligence, they also began to train carrier pigeons, because carrier pigeons are still a new thing, so at present, they only let carrier pigeons fly a few times in the city and outside the city, and they can't engage in long-distance communication, but this is enough for Liu Ziqiu

According to the news sent from the city, the drainage culvert was located in the south of the city, and the two exits of Yong'an Canal and Qingming Canal did not attract the attention of the defenders in the city, and there were no soldiers guarding the surroundings, but the exit located in Longshou Canal was within the palace wall, and the secret spies sent into the city by Liu Ziqiu could not find out the results for the time being

Although he did not know the situation of the exit, Liu Ziqiu still decided to act as planned, late that night, the army quietly came to the Guangtong Canal, a group of soldiers waded into the river, the entrance of the drainage ditch was overgrown with wild grass, if there was no Yu Wenkai's guidance, it would be impossible for ordinary people to find these entrances, it is the dry season, the water in the culvert is not deep, about only to the calf, but the weather in early spring is unusually cold, not far away, many soldiers' legs and feet are beginning to numb, and from time to time there are one or two disgusting mice scurrying under their feet

Liu Ziqiu walked at the front of the team and whispered: "The brothers insist on living in the city is victory."

The soldiers gritted their teeth and persevered, and after a while, they came to a fork in the road, Yu Wenkai walked a few steps in front of Liu Ziqiu, and said: "The lord leads to the south of the city to the left, and leads to the palace city to the right."

In fact, Liu Ziqiu wanted Yu Wenkai to stay outside the city, after all, a talent like Yu Wenkai who is proficient in construction, machinery, water supply and drainage is very scarce and valuable in this era, Liu Ziqiu is reluctant to let him take risks, but when Yu Wenkai heard that Liu Ziqiu was going to personally walk the dark passage of Longshou Canal, he insisted on following Liu Ziqiu, and even did not hesitate to die, Liu Ziqiu was smashed, but he had to take him with him

Listening to Yu Wenkai's resolute words about the direction of these forks in the road, Liu Ziqiu nodded and said, "Lord Yuwen, you go to the left, everyone acts separately."

The situation in the south of the city has been discovered, and there are spies lurking in the city to respond, and it is relatively safer to go to the left, and the exit of the Longshou Canal is in the palace city, and I don't know what the situation is around the palace, and I don't know what the situation is, which means that the risk is greatly increased, but Yu Wenkai did not agree, gritted his teeth and said: "The subordinates follow the lord."

Liu Ziqiu didn't expect this polite Xianbei person to be stubborn, so he had to nod and let him follow

Walked forward for more than five miles, and a smell gradually drifted from the culvert, this smell was not the kind of foul smell that Liu Ziqiu originally imagined, on the contrary, there was a faint aroma of fat powder, in fact, these culverts are connected with the rivers in the city, the water in the culvert is relatively clear, in this era, manure is an important farm fertilizer, it will not be discharged into the culvert, that is, some domestic sewage is much cleaner than later generations, the biggest difficulty in the culvert is not these sewage, but from time to time will encounter some low places, it is very difficult to pass

However, for Liu Ziqiu, who has been training for many years, these difficulties are nothing at all, and under his leadership, the team still moves forward smoothly

……

In the culvert, there is no daylight, but a glimmer of dawn has risen on the horizon in the east outside the city, Zhang Liang ordered a feint attack on the north of the city, in order to make the feint more realistic, Liu Ziqiu allocated Zhang Liang 20,000 foot soldiers and 5,000 cavalry cavalry, cavalry galloped under the city, one by one feathered arrows shot at the head of the city, trying their best to suppress the defenders of the city, the war drums sounded, a group of soldiers carrying a long ladder and shouting rushed to the head of the city, in addition to the rushing car used to hit the city gate, the shrimp toad car to fill the moat, the ladder to climb the city wall, Attacking from outside the city, the tall arrow towers that could move were thrown into battle

After all, the defense of Chang'an City was much stronger than the counties they encountered along the way, and a cart of mud soldiers could only fill in a few narrow roads on the moat, and it was impossible to completely fill the moat, as for the tall city walls, the long ladders used in the army could not even reach the battlements, and the city was well guarded, and the arrows were like rain, Zhang Liang's men suffered heavy casualties, but it was difficult to step on the first step of the city

In fact, Liu Ziqiu only explained that he was only a feint, and he was not allowed to make such a desperate posture at all, but Zhang Liang himself was bent on making meritorious contributions, and the so-called generals were not affected by the life of the monarch outside, since Liu Ziqiu handed over this army to him, he had to do his best to turn the feint into the main attack

Seeing that the casualties of his subordinates were getting heavier, Zhang Liang gritted his teeth and said viciously: "Someone has come to push the trebuchet over."

Left and right hurriedly persuaded: "General Qiyu has ordered that trebuchets must not be used in this attack on Chang'an City."

Zhang Liang said undoubtedly: "Execute the order"

The military order was like a mountain, and the subordinates had to push the trebuchet out, at that time, there were 800 trebuchets in the army, most of which were concentrated in Mu Duoli's barracks, but because of the rush of time, there was no time to concentrate all the trebuchets, and Zhang Liang's army still had more than 100 left

Although there are only more than a hundred trebuchets, but the power should not be underestimated, with Zhang Liang's order, the trebuchet slowly started, and there was a deafening rumbling sound outside the city, Yang Xuangan couldn't help but be shocked when he heard it in the city, and asked: "What is this movement?"

Left and right, but no one can answer, just here, the sky is dark, countless stones are falling all over the sky, Liu Ziqiu equipped the trebuchet with many kinds of stone bullets, Zhang Liang's first wave of projectiles is a kind of small stone bullets, each is only the size of a baby's fist, a trebuchet can throw dozens to hundreds of this kind of stone bullets, not to say to the city wall, that is, to the general buildings have no lethality, but this kind of stone bullet is still quite powerful on people, the light head is broken, the blood is heavy, so it is killed, Zhang Liang threw this stone projectile The purpose is mainly to adjust the impact point of the trebuchet, because the large stone bullet is not convenient to manufacture and transport, so it is necessary to use a small stone bullet to try to attack firstangle

Yang Xuangan, who has been well-informed in the army for many years, couldn't help but be taken aback, and said repeatedly: "It's not good, the thunderbolt car is ready to prepare the big shield."

It is still very effective to deal with this kind of small stone bullet and big shield, but if the other party replaces it with a large stone bullet, even if it hides in the house, it is useless, and if a huge stone bullet falls from the sky, almost the house can be directly collapsed

At this point, Zhang Liang had already ordered to adjust the angle of the trebuchet's projectile, the second round of bullet rain "crackling" fell on the city, the defending soldiers were smashed everywhere, and the soldiers who were acting as feints in the north of the city took the opportunity to rush closer to the city, and several ladders were even set up at the head of the city, seeing that the attack position of the trebuchet had met his own requirements, Zhang Liang then ordered: "Change the large one"

The weight of a large stone projectile is worth thirty small stone bullets, and it takes two soldiers to work together to put it into the trebuchet, more than ten soldiers twist the iron cable together, "boom" a loud sound, the huge stone projectile in the sky across a beautiful arc, mixed with sounds, sharp whistle, accurately hit the city wall on the north gate, the entire north wall of Chang'an seems to be shaking, the defenders on the city are in a panic, after a blow, a huge crack has appeared above the north gate

Zhang Liang ordered again: "Reload and prepare"

"Wait," suddenly a group of cavalry galloped up, and Mu Duoli sat down and shouted loudly, "Who gave you permission to use the trebuchet?"

After the first wave of trebuchet attacks, Mu Duoli, who was guarding outside the eastern city, heard the movement and hurriedly led a team of personal soldiers to rush over, and during this time, Zhang Liang carried out two more waves of attacks, and the fourth wave of large stone projectiles had also been loaded with trebuchets

In Zhang Liang's eyes, Mu Duoli was just a woman snatched by Liu Ziqiu, so he looked down on Mu Duoli at all, but Mu Duoli's archery skills also made him admire it very much, especially Mu Duoli's divine arm bow was a treasure he dreamed of, seeing Mu Duoli coming, Zhang Liang still pretended to be respectful and said: "Madame does not need trebuchets to break through the city wall, and the end general can't bear to see the casualties of the soldiers too heavy."

As he spoke, Zhang Liang quietly made an attacking gesture behind him

Although most of the soldiers in the army knew that Mu Duoli was Liu Ziqiu's woman, in today's battle, their commander was Zhang Liang, and they must unconditionally obey Zhang Liang's orders, unless Liu Ziqiu personally intervened to stop it, on the other hand, only some of the nearest trebuchet operators could hear Mu Duoli's words, and the distant trebuchet operators did not know what was going on

So when Zhang Liang made a gesture, most of the trebuchet operators began to pull the iron cable, and the loud sound of "boom, boom" completely covered Mu Duoli's voice, Mu Duoli could only watch another batch of stone bullets rise into the air and shoot towards the north gate of Chang'an City.
