Yuliang Road is a means of siege. It is to carry out civil construction outside the city and build a slope with the end of the slope being flush with the city head. In this way, the infantry and cavalry of the siege troops can directly rush up the slope and go straight to the city. However, the Yuliang Road project is huge, and the auxiliary soldiers who built Yuliang Road have to carry out construction with the firepower of the defenders at the top of the city. Such a project is difficult to complete without more than a month, so it was not within Dorgon's consideration at the beginning.

But Shang Kexi thought of a way to use ice water to build a Yuliang Road from the art of defending the city with ice water.

"Master, we can pile up pickles under the city. After they are piled up, water them on it. When it is strong, pile up pickles and water them on it. This will take no ten days to build a Yuliang Road to the top of the city." Shang Kexi said.

"Good idea!" Dorgon was overjoyed, stood up immediately, and ordered Baoyi Aha and others to prepare shield chariots and mabaos.

After a day of preparation, after dark, the Qing army began to attack again.

Baoyi Aha and his men pushed the shield chariots loaded with macao and slowly advanced, preparing to build a Yuliang Road outside the city with the help of the night. However, in winter, the visibility was high, and the defenders at the top of the city discovered Baoyi Aha, who was busy under the city.

"General, Jiannu did not attack the city one day, and Jiannu had made any moves under the city tonight." Zeng Tao woke up Li Hong who had already fallen asleep.

Li Hong got up from the bed: "Let's go, let's go to the top of the city to take a look."

The group of people went up to the top of the city, and the soldiers on duty at night saluted Li Hong: "Good thousands of households."

Li Hong stood at the top of the city, and with the help of the light in the snow, he found that the Qing army Ahas were busy in the open space a mile away from the city, transporting sandbags in large trucks and spreading them on the ground. When the sandbags piled up to one person, the Ahas carried buckets and poured buckets of water on the sandbags.

"General, what are Jiannu busy with?" Chen Xu asked.

"No! They are building the Yuliang Road!" Li Hong, who had been deeply involved in the true offensive and defense of Li Guodong, understood immediately.

"Yuliangdao? What?" The people next to them were stunned.

"It's a slope that starts from one mile outside the city and extends to the top of the city. When Jiannu's Yuliang Road is repaired, their cavalry will rush up directly! Shield chariots can also be pushed to the top of the city, so we will be in trouble." Zeng Tao, who was a military family, knew this, and he answered for Li Hong.

"Then how do we break the enemy?"

"We can't let Jiannu repair the Yuliangdao! Let's go out of the city to fight back!"

"We have few people and can't leave the city. If we wait until Jiannu gets closer, we will greet the firearms on the cityside!"

"That can't be stopped. Jiannu died at most, and he could repair the Yuliangdao."

"We will be in trouble when they fix it."

There was a lot of discussion on the city wall.

Li Hong called Zeng Tao over and whispered in his ear: "You organize all the civil and political soldiers who are responsible for helping defend the city..."

At dawn the next day, a slope twenty feet long and ten feet high at the end were seen, with a slope four feet wide. After dawn, the Qing army was still busy. Baoyi Aha and his men pushed the cart and kept transporting the marinades over and putting them on the ground. Aha behind them carried a bucket and watered them on top.

Further apart, the Baoyi Aha and others pushed the cart to Xiaoheihe not far away. Some Ahas were busy on the river surface, chiseling out ice layers, making buckets of water from the river, and then put the water on the truck and put the lid on it to prevent the water in the bucket from freezing during the transportation process. The water transport vehicles were transported to the construction site outside the city, and the Ahas picked up the bucket and poured it on the sandbag. Li Hong looked further away and saw some Ahas took empty macao and went to the nearby snow and put a shovel of ice and snow into the macao, which quickly made bulging macao. The prepared macao was sewn with a hole, put it on a large truck, and transported it to the construction site. Then the Ahas and others threw the macao on the ground and piled it up.

"Fill the marijuana with snow and then water it with ice water. Jiannu's construction at such a speed may take less than seven days before the Yuliang Road will be completed!" Li Hong was shocked. He prayed silently in his heart, hoping that Zeng Tao's speed would be one step faster than the Qing army.

With Aha's construction, the Yuliang Road slowly advanced forward. Three days later, the construction site of the Yuliang Road had entered the range of the defenders at the city.

The construction of Baoyi Aha and others installed wooden shields on the big chariots and turned into shield chariots. The Han Eight Banners soldiers, Man Eight Banners soldiers and Mongolian Eight Banners soldiers also began to get busy. The Qing soldiers stood behind Baoyi Aha and others holding whips and steel knives. If someone was passively slacked off, they would immediately whip down. Once they were shot on the top of the city and someone retreated, they would be beheaded on the spot.

Wu Zhenchao Ha Camp had set up artillery, Wu Zhenchao Ha Camp bird gunner and Man Eight Banner archers stood behind the shield cart, and Aha in front pushed the cart step by step towards the city.

As the distance approached, the battle began to begin under the city.

The Qing army's firepower suppression method was still the old routine. The bird gunners and the archers of the Manchu Ha camp of Wuzhenchao shot at the top of the city to protect Aha and threw the mabags to the ground. The defenders at the top of the city fired violently at the bottom of the city with bows, bird guns, tiger squat cannons and Fran machine cannons, making Aha who was under construction fall down one after another. Some Aha turned around and wanted to run away, and immediately cut off his head by the Eight Banners soldiers behind him, and his bloody head was lifted in his hand to deter other Ahas.

The tiny feather arrows shot under the city also caused certain casualties to the top of the city. Although the casualties of the siege were much greater than those of the defenders, most of the casualties of the siege were Aha. The losses of the Eight Banners soldiers were minimal, and even the Eight Banners soldiers in the Han Dynasty did not suffer any losses.

Li Hong at the top of the city has been well-known to Li Guodong and is also very good at treating the wounded.

The wounded soldiers lifted from the top of the city were all disinfected and treated. Li Hong asked someone to clean the wound with strong liquor, and performed surgery on the wounded soldiers who were shot. The projectiles and arrows were dug out. The knife used for the operation was boiled in boiling water. Finally, the gauze that bandaged the wound was also boiled in boiling water. With good treatment methods, Li Hong saved the lives of many defenders.

As the Yuliang Road advances, the battle under the city entrance has entered a fierce heat.

The Baoyi Aha and others had already entered the attack range of wolf teeth, yaksha squid, lime bottle and turbulent oil tank on the city. Among the projectile arrows shot from the city, there were lime bottles and stones. From time to time, yaksha squid and wolf teeth were smashed, and the hot golden juice fell from the city.

During the last section of Yuliang Road construction, the defenders at the city top dropped a tinder tank, then shot rockets, igniting the underworld into a sea of ​​fire. The scattered buns filled with snow were burned, and the snow-filled ice inside was preheated and melted into ice water and flowed away. The bulging scattered buns immediately faded.

The turbulent oil tanks burned wildly, and several shield trucks that had no time to withdraw were also burned.

The defenders at the top of the city threw out their claw hooks, grabbed the shield, pulled them hard, and pulled them off. Then the arrows and projectiles on the top of the city greeted the Ahas who were not covered with armor like it was raining.

"It's all a group of pigs!" Dorgon roared in anger, "In order to be lazy, the last paragraph is filled with ice and snow in the last paragraph? If the order is sent, the last paragraph is filled with soil, sand and gravel. If there is only Ah's servant who dares to be lazy, he will definitely be killed!"

It is not easy to dig soil, sand and gravel in winter. After the ice and snow were lifted, the ground was as hard as pig iron. Ahas were scrapped and dug out the soil and put them in the mash. However, these mashing bags were not afraid of being burned by fire. Under the supervision of the Eight Banners soldiers, Ahas pushed the shield cart to the city, threw the mashing bags filled with soil on the ground, and piled up them.

The closer it is to the city wall, the greater the casualties of Baoyi Aha. However, these casualties are within Dorgon's tolerance.

Seven days later, the Yuliang Road paved at the cost of Aha's life was finally completed! It leads from the Qing army camp to the edge of the city wall. Although there is still a gap from the city wall, this gap can make people jump over with their horses.
Chapter completed!
