The morale of Zhou Bo and Zhou Yafu's camp declined. The Han army attacked Chang'an City for five consecutive days, but it was difficult to attack.

Chang'an City was already a small city and expanded into a medium city. Fifty thousand Han troops attacked Chang'an City day and night, with 9,000 casualties and no progress was made.

"Zhang Hua is likely to return to Chang'an, my father, we can only try for one more day at most. If we can't succeed, we must withdraw our troops."

Zhou Yafu inspected the injured soldiers, personally asked about his well-being, and expressed his own opinions to Zhou Bo.

Zhou Bo disagreed: "Zhang Hua could not allow Li Keyong's Ya'er Army to ignore it and return to Guanzhong unless Zhang Hua doesn't want Hedong anymore. Hedong is the barrier of Guanzhong. If Hedong is lost, Guanzhong will be threatened at all times."

Zhou Yafu asked someone to take the topographic map and said to Zhou Bo: "My father, please look here. According to the topographic map drawn by our scouts, the Great Jin Kingdom built a Yubi City here. The Yubi City is located in a high wall and is surrounded by the Fen River. The east, west and north sides are deep ditches and huge ravines. The terrain is abrupt and steep, and it is difficult to attack and eliminate."

"If the Xia army stationed troops here, 20,000 to 30,000 troops would be enough to delay the Ya'er army for several months. This period would be enough to allow the Xia army's extra troops to return to Chang'an."

"The child estimated that his progress might have crossed the Yellow River. Therefore, we only have one day at most."

Zhou Yafu conducted an incisive analysis and saw Zhang Hua's intentions.

Zhou Bo followed Zhou Yafu's analysis: "Even if this happens, if Zhang Hua returns to Chang'an from Yubi City and the army is mobilized, we will definitely receive the news in advance. Moreover, time will not be so tight."

Zhou Yafu shook his head: "Did your father ever think about whether Zhang Hua would make a quicker progress if he abandoned his baggage and only led a light cavalry to attack?"

"hiss……"

When Zhou Bo heard his son's analysis, he had to admit that Zhou Yafu's analysis was reasonable.

"Tomorrow, attack Chang'an again. If you can't take Chang'an City, then you can do this."

Zhou Bo finally recognized Zhou Yafu's proposal.

The Han army rested and waited for the city to be attacked tomorrow.

Even with Zhou Yafu's pessimistic estimate, Zhang Hua's advance would not be so fast.

Late at night, most of the Han soldiers in the camp fell asleep and recovered their strength. From time to time, they could hear the roar of tigers from the deep mountains and forests.

Zhou Yafu set up layers of open whistles in advance and secretly to prepare for a night attack.

"We all went to Chang'an City, but we were unable to take Chang'an City. We didn't know when we could take the entire Guanzhong."

"These things are not what we soldiers care about. I only know that the dry food we carry will be finished soon. If we can't catch Chang'an, we can only return to Chencang."

A small team of Han cavalry patrolled the outside of the camp, chatting from time to time to keep themselves energetic.

Suddenly, murderous intent suddenly appeared. In the darkness, more than a dozen strange poisonous arrows cut through the darkness and hit the Han cavalry!

The poisonous arrows sealed the throat, and three Han cavalry rolled down from the horse's back, their faces turned blue and foamed at the mouth.

"No, the enemy attacks!"

The three Han cavalrymen were open whistles, and the two Han soldiers hiding in the dark saw that the open whistles were shot and killed. They knew that the enemy had attacked at night, so they immediately took out the arrows.

However, several figures seemed like ghosts. They appeared behind them. The dagger covered with venom cut off the throats of the two Han soldiers' secret whistles and wiped them out!

The commander Zhang Dachuan, wearing a night-walking clothes, led a team of sentries in Yewu, to clear the open and secret whistles deployed by Zhou Yafu in the dark.

As a professional scout, he was familiar with the way the army deployed open and secret whistles. Therefore, on the premise of not disturbing the other party, he cleared the sentries and covered Zhang Hua's cavalry to approach Zhou Yafu's camp.

Zhang Dachuan led Ye Busuo, and advanced a hundred meters forward, killing more than 60 sentries.

The density of sentries deployed by Zhou Yafu on the periphery was outrageous. It was also very difficult to clean up Zhou Yafu's sentries when Zhang Dachuan was not resuming at night.

Less than 100 meters away from Zhou Yafu's camp, Zhou Yafu set up a double-layer secret sentry. When Zhang Dachuan killed the first layer of secret sentry, the sound arrows shot from the second layer of secret sentry alarmed the other sentry set up by Zhou Yafu.

"Zhou Yafu is worthy of being the god of military management. Even if he doesn't stop at night, he cannot completely break through the secret whistle set up by him. Since he has been discovered, ignite the torches and capture the Han camp!"

Zhang Hua led 20,000 elite cavalry, followed Zhang Dachuan's Yebusuo and approached the Han army camp.

At this time, the cavalry generals such as Mulan, Chen Qingzhi, Ma Fonian, Yang Ye, and Lu Lingqi pulled out their weapons and led their respective cavalry to step onto the Han camp!

“Destroy the antlers!”

Yang Ye carried a big knife and flipped his wrist. The golden sword energy illuminated the nearby defenders and hit the antlers straight!

boom!

The antler was cut by the irritable knife energy, and a gap of one meter wide appeared!

The Yang family army dismounted and destroyed the antlers so that the subsequent cavalry could advance straight into the future.

The cavalry crowded in the rear shot archery rain at the Han army camp, and some Han soldiers who came out of the camp tent were shot and died.

The Han army camp was suddenly attacked by elite cavalry, and the attack came from an unexpected direction, and was panicked. The Han army generals hurriedly shouted, summoned the troops under their command, and asked these personal soldiers to gather quickly.

The copper brazier capsized and the flames spread, which further aggravated the chaos in the Han army camp.

Zhang Hua's cavalry company broke through four levels of antlers and drove straight in!

"Don't panic!"

Zhou Yafu was wearing armor and came out of the big tent, and his talent was launched to forcibly suppress the chaos of the Han army!

The originally panicked Han army suddenly returned to calm and had a clear look.

At this moment, the Han army seemed to understand what they were going to do, gathered in their respective lieutenants and generals' tents, and under the leadership of various Han generals, they fought hard to resist the assault of the Xia cavalry!

"It's not moving like a mountain!"

Zhou Yafu's talent further improved the capabilities of the Han army. The true qi of the Han army was connected to each other, forming a cloud of qi above the Han army camp, greatly enhancing the defense of the Han army. The battle formation can also share part of the damage suffered, which is indestructible!

Under the influence of Zhou Yafu, the Han army did not collapse immediately because of the raid of 20,000 elite cavalry, and remained calm.

"Even so, we will defeat this Han army!"

Zhang Hua discovered that Zhou Yafu's Han army was calm, but his 20,000 elite cavalry had already penetrated and had to defeat the Han army.

Zhou Yafu made the Han army calm down, but at unexpected speed, the elite cavalry of the Xia army that was stepping onto the camp still had an advantage.

Chen Qingzhi's talent for running was effective, and the white-robed army was as fast as the rushing river, quickly splitting the Han army.

Yang Ye, Deng Ai, and Lu Lingqi's cavalry were also quickly interspersed in the Han camp.

Tens of thousands of Han troops were divided into several parts and each fought for their own battles. The battle formation clouds above the Han army camp were also divided into several parts, and the formation effect was reduced.

"Zhang Hua's return is too fast."

Zhou Yafu tried his best to command the Han army, trying to maintain the formation of the Han army when Zhang Hua's iron-hoofed horse stepped onto the battalion, but was still shocked by Zhang Hua's cavalry's raid speed.

According to Zhou Yafu's calculations, Zhang Hua will have to return to Chang'an at least two or three days.

Zhang Hua's march speed was faster than Zhou Yafu imagined. Zhang Hua just learned that Chang'an was threatened, so he immediately selected cavalry and returned from Yubi to the army, traveling day and night to win quickly.

"Fires appeared in the Han army camp, and shouts of killing were everywhere, not like a fraud. Could it be that the lord has returned to the army?"

"Yulin Army, bring the torches and follow me out of the city!"

Xue Rengui counted three thousand Yulin cavalry, left Chang'an City, cooperated with Zhang Hua to attack the Han army camp quickly.

Zhou Yafu's camp was attacked from front to back and forth, and was attacked from both sides.

Even if the Han army remained calm, they were in a tough battle.

Xue Rengui took the lead, Fang Tian waved his painting halberd and made a sound of breaking through the air, killing a Han army captain, and his head flew up!

Three thousand Yulin Army equipped with Mingguang Armor drove straight in and ran away from the Han army along the way!

The Yulin Army on both sides threw the torches into the Han army camp tent and burned the camp!

Several cavalrymen rushed around the Han army camp and destroyed the Han army.

Zhou Yafu's battle formation failed to work and was destroyed by the Xia army's cavalry.

"After this matter, I can only leave the camp and leave."

Seeing the fires rising in the Han army camp, Zhou Yafu knew that he could not hold on. After gathering the eight thousand Xiliu camps and a group of ordinary Han army, he informed other Han army generals to prepare to break through.

Under Zhou Yafu's leadership, the Eight Thousand Xiliu Camp was orderly and responsible for opening the way and attacking Chen Cang. When they met Yang Ye's Yang family army, they defeated the Yang family army!

The Yang family army fell into the square formation of Xiliu Camp, and all abilities were suppressed by Xiliu Camp, and even Yang Ye's force decreased.

The cavalry of the Yang family slashed the shield of the infantry of the Xiliu Camp. Part of the damage suffered by the infantry of the Xiliu Camp was distributed as a whole. The soldier of the Xiliu Camp seemed to be fine, and took the cavalry of the Yang family with a gun off the horse.

"What's going on? Both strength and speed are suppressed..."

Yang Ye danced wildly with a big sword, causing a bloody storm and killing dozens of people in a row, but he was not breathing smoothly. He was suppressed by Zhou Yafu's military formation and seemed to be trapped in a swamp.

Not only Yang Ye, but also the Yang family army was affected by Zhou Yafu's battle formation. The cavalry's speed decreased and was attacked by the Xiliu camp, causing heavy losses.

Xiliuying cooperated with tacit understanding and joined forces to kill the cavalry of the Yang family army, and the casualties between the two sides were not proportional.

Yang Ye could only rely on his personal force to kill the soldiers of Xiliu Camp as much as possible and lead the Yang family army to break the formation.

Zhou Bo drew out his long sword, avoided Yang Ye, killed the Yang family army, killed several people in a row, and helped Zhou Yafu's Xiliu Camp break through.

The battle outside the city alarmed all the defenders and rural brave men in Chang'an City.

This battle is related to the safety of Chang'an City, and more than 100,000 residents of Chang'an City are waiting for news.

Ministers such as Xie An, Han Fei, Yao Chong couldn't sleep all night and were anxiously waiting for the results.

Their interests are consistent with Zhang Hua. If this battle can be won, it can consolidate the rule of Zhang Hua's power over the 800-li Qinchuan and achieve great things, otherwise Guanzhong may be shaken.

Dozens of Confucian scholars from Zhongtian Pavilion Academy were also watching the battle. In the distance, the Han army's camp was rushing into the sky, and the shouts of killing were shaking the sky and the earth, so that the entire Chang'an City could be heard.

These Confucian scholars have experienced several days of baptism and separation from life and death, and their eyes have changed significantly.
