When Zhao Kuangyin won again and again, Chai Rong stayed in Shouzhou for several months, but still stood still. Because the urban management of Shouzhou City is called Liu Renzhan, he is a member of the Southern Tang Dynasty. Under his leadership, the army is strictly managed and soldiers obey orders. At first, it was Guli who was sent to attack Shouzhou City. Later, Chai Rong led a great army to make a personal expedition and began a confrontation with Liu Ren.

After Chai Rong arrived in Shouzhou, he immediately ordered heavily to surround Shouzhou. Chai Rong's first move was to surrender. Although he knew that Liu Renzhan would not surrender in Kaesong, Chai Rong expressed his appreciation for Liu Renzhan. As long as Liu Ren obediently opens the door, he will ensure that Liu Renzhan has high officials and high salaries. As expected, Liu Renzhan is a rich man who won't commit adultery. He refused Chai Rong's inducements and swore an oath in front of Chai Rong.

This is tantamount to tearing your face. Chai Rong immediately returned to the barracks to find Coulee and asked him about the weakness of guarding could. There is no doubt that if Coulee knew the weakness of Shouzhou City, he would not have attacked for a month without making any progress. Chai Rong personally surveyed Shouzhou City around carefully, and immediately found the weakness of Shouzhou City. The weakness is the feishui outside Shouzhou, where the Eastern Jin Prime Minister Xie An and the former Qin Emperor Fu Jian fought.

The south wall of Shouzhou is the weakest in defense, because the moat in the south is connected with the water at the foot of the mountain, occupying the geographical advantage. The slings used for siege can't play a role in the water at the foot of the river. This is also the reason why Liu Renzhan can't break through the south wall even though he knows the weakness of Shouzhou City.

Chai Rong immediately ordered the shipbuilding. Since the trebuchet could not be put in the water, he put the trebuchet on the ark. Liu Renzhan never imagined that Chai Rong still had this skill. He never thought that someone would use the trebuchet from the south gate, because the south is full of water, which makes him feel very safe, but often the safest place is the most dangerous place, and unpredictable dangers will await him. The ark was soon built, and Chai Rong ordered all the trebuchets to be moved to the ark.

Liu Renzhan was shocked when he saw these creative gunboats, and a chill rose from his heart. A series of gunboats on the water began to bombard, and the destructive boulder flew to the south gate of Shouzhou. With a loud noise, stone chips splashed on the south wall, and tiny cracks appeared. Liu Renzhan is Liu Renzhan, and he immediately thought of playing with a winch crossbow. As soon as this weapon appeared, Chai Rong immediately felt the pressure.

At the same time, Liu Renzhan also considered the problem of strengthening and defending Shouzhou City. He took the opportunity to mobilize soldiers to repair the wall broken by boulders and fill in the depressions and grooves in the wall. With a genial smile, Chai Rong had to order an immediate retreat to recover some losses, otherwise it would be too late. Chai Rong didn't know that Liu Ren Zhan was not an easy man at the moment, but it happened that Chai Rong was also a stubborn and paranoid man, and he wouldn't stop until Shouzhou was captured.

After the defeat, Chai Rong decided to launch an all-out attack on Shouzhou City. Disperse Liu Renzhan's troops, implement forced breakthrough tactics, and fully capture Shouzhou City. Because Shouzhou City was too high and the city defense was solid, the troops in the late South Tang Dynasty were commanding and occupied a geographical advantage. Therefore, Chai Rong specially invented a patent called "Bamboo Dragon". In the first month of the third year of Zhou Xiande, Chai Rong officially launched a general attack on Shouzhou City. On the one hand, the soldiers on the bamboo dragon shoot arrows and throw stones at Shouzhou City.

On the one hand, send infantry to attack the four gates in the southeast and northwest of Shouzhou City. In addition, a gunboat was sent from the water at the foot to shell Shouzhou City. These three roads, three-pronged, do not leave opponents a chance to breathe. However, Shouzhou City still stands, and the war lasted from the first month to April, day and night. The sergeant of the later Zhou Dynasty took turns to go into battle, exhausted, but unable to step into Shouzhou City. Chai Rong felt very helpless. Throughout April, the weather became extremely abnormal and there was a great summer heat.

Chai Rong's army also suffered from heavy rain, which is what we call the rainy season. It is very hot in April, and the evaporation is very strong. It basically rains cats and dogs every day. The barracks in the last week were flooded, and countless soldiers drowned. The bamboo dragon gun boat was either flooded or washed away. In this case, Chai Rong held a military meeting, and everyone agreed to temporarily withdraw. Chai Rong left Li Zhongjin to continue to besiege Shouzhou, and then sent troops, without giving Shouzhou a chance to breathe. In this way, Chai Rong left Shouzhou with regret.
