After a moment, Lu Han ran to Zhang Xuan, turned over and dismounted, stepped forward and bowed and said, "I am not good at ease, please see Your Highness!"

"It seems that Lu joins the army is not going well, right?" Zhang Xuan asked with a smile.

"Reporting to your highness, it's not just a bad situation, it's just a piss-up!"

Lu Han then explained in detail the matter of him entering the city to deliver the letter. When Du Fuwei tear the letter to pieces, Zhang Xuan quickly flashed a horrifying murderous intent, and he asked without saying a word: "What?"

Lu Han talked about Du Fuwei's intention to kill him, and finally said: "Fu Gongyou grabbed Du Fuwei and saved Beiyi from the disaster. Beiyi's mission was not good, and he was very ashamed to fail to complete the task assigned to him by His Highness!"

Lu Han was indeed ashamed. He had a deeper task. If Du Fuweikan had a detailed discussion with him, he would persuade him. Unexpectedly, Du Fuwei would not give him this opportunity at all and directly tore up the letter, which really made him extremely frustrated.

At this time, Du Ruhui next to him asked, "Is it Fu Gongyou who saved the military?"

"It should be that Bei Yi Ren felt that Du Fuwei was going to kill me, but Fu Gongyou didn't say a word. As soon as Du Fuwei left, he directly ordered his personal soldiers to send me out of the city. Bei Yi could not understand his true intentions."

Sighing, Lu Han said again: "I have let down Your Highness's entrustment, please punish me!"

Zhang Xuan said lightly: "This is as expected by me. Lu Zongjun doesn't have to blame himself. I just asked you to deliver a letter. Since the letter has been delivered, the matter is over. Lu Zongjun goes to rest!"

Lu Han thought about it and it seemed that His Highness did not let him persuade Du Fuwei. He felt a little relieved, so he bowed and retreated.

At this time, Du Ruhui smiled and said, "Does Your Highness feel that Fu Gongyou's attitude is a bit subtle?"

Zhang Xuan shook his head, "Fu Gongyou and Du Fuwei are friends who are slashing their necks. Even if he has any ideas, he will only try his best to persuade Du Fuwei and will never betray him. But Du Fuwei has done things so Fu Gongyou feels that there is no hope of reconciliation, so he has no extra words. If Keming puts his hopes on Fu Gongyou to trigger internal strife, it would be a big mistake."

"Maybe! I'm overthinking."

Du Ruhui asked again with a smile: "When will your highness start an attack?"

Zhang Xuan looked at the busy dredging soldiers and said slowly: "If nothing unexpected happens, the attack will be launched in five days at the latest. As long as we are prepared, the shorter the time to capture Hefei City."

The battle to attack Hefei was Zhang Xuan's longest siege, but the reason was very simple, because there was not much time left for them, and the wind direction had changed and he could no longer transport grain from water to Hefei. The 80,000 Sui army currently had only more than one month of grain storage.

If they cannot conquer Hefei within a month, they can only withdraw their troops temporarily and launch a new offensive in the spring of the following year, but in this way, all their previous efforts to the camp will be in vain.

In order to win Hefei City as quickly as possible, the only way is to prepare well and consider everything clearly. In particular, we must know ourselves and the enemy. How will the other party defend the city and how should they deal with it?

At night, in the navy camp, hundreds of shipmakers were busy processing three building ships. These three building ships were all three thousand stone warships. The tower was three stories high and just level with the head of Hefei. As long as the ship leaned against the city wall and directly put on the hanging board, soldiers could rush up to the head of the city from the bow.

But how to prevent the attacks of catapults, stone cannons and rockets at the city entrance of Hefei is a key issue. They not only need appropriate siege tactics, but also technical protection.

The shipmakers made a wooden shelf on the left hull and front facing the city wall, and a layer of leather was stretched on it, usually using cooked cowhide. In this way, the three large ships seemed to be wearing armor, enough to withstand the fierce attacks of scattered machines and stone cannons for a while.

The temporary dock was brightly lit, and hundreds of craftsmen were busy working overtime. On the shore three miles away, it was a different situation. The lake water along the coast was very deep, and the large ship could directly dock. The Sui army built a city wall about a hundred feet long on the shore, which was exactly the same as the city wall of Hefei.

Zhang Xuan sent more than a thousand bravest soldiers to stand on the city wall to defend, and the warships led the soldiers to dock and attack the city in turn. Except for the blunt sword, blunt spear, and headless arrows, everything else was like real wars. Both sides fought desperately. For seven days, soldiers died unexpectedly in the siege battle almost every night. Some fell off the city wall, and some died of serious injuries to the head by blunt swords.

Tonight, the general Su Dingfang was the one who defended the city, while the other who attacked the city was the one who fought desperately. Qin Yong had been following Zhang Xuan and had grown into a young general of eighteen or nineteen years old. He had accumulated merit and was promoted to Yingyang Lang. He is currently Zhang Xuan's direct subordinate.

Just last year and the previous year, his figure soared, reaching six feet and five feet tall, equivalent to 1.9 meters tall in later generations. He had a large bra and a round waist and a huge arm strength, making him a long-handled and big copper hammer weighing 120 kilograms.

Thanks to Li Jing's careful teaching, Qin Yong's hammering technique was very exquisite and he was already perfect. In last year's internal competition, Qin Yong defeated more than 30 generals in a row and squeezed into the ranks of the Eight Tiger Generals of the Northern Sui Dynasty. He ranked sixth after Pei Xingyan, Luo Cheng, Su Dingfang, Luo Shixin, and Wei Wentong. Behind him were Yuchi Gong and Xiong Kuohai. Because of his extremely brave battle, he was praised by the soldiers as the "desperate three-man" and his popularity even surpassed Luo Shixin, the Overlord Gun of the past.

Since this is training soldiers, the generals are not allowed to go into battle. Seeing that the time for an incense stick is approaching, Qin Yong yelled in a hurry. His soldiers have been defeated continuously and cannot climb to the top of the city. He wished he could pick up the copper hammer and rush forward to fight fiercely.

At this time, a brigade coach was injured by two blunt knives and screamed and fell off the board. Someone hurriedly reported to Qin Yong, and Qin Yong shouted: "Don't stop, continue to attack the city!"

He took off his armor and jumped into the lake. Soon after, he found the injured brigade coach and lifted him out of the water. A small boat that had been patrolling and rescued came forward. A soldier reached out to pick up the injured. Qin Yong shouted in a hurry, "Are you blind? Be careful with me, his left shoulder is broken!"

The soldiers next to him were so scared that their faces turned pale and quickly reminded him, "General, please see clearly."

Qin Yong raised his head and was stunned. It turned out that the soldier was no one else, but his coach Zhang Xuan. Qin Yong was so scared that he shivered. The coach of the troop almost fell into the water again. Zhang Xuan carried the injured soldier onto the boat, slapped Qin Yong with a scalp, and cursed with a smile: "You guy dares to scold me, you are very brave!"

"The conscience of heaven and earth is dark at night. I didn't see clearly. If I knew it was a great commander, I would never dare to fart!"

Zhang Xuan knocked him hard on the back of the head, "I'm still talking nonsense. You should be asked to follow Cheng Yaojin. I found that you are suitable for being his apprentice."

Qin Yong scratched his scalp and said nervously, "Mr. Marshal, don't! That Mr. Cheng, I only admire him."

Zhang Xuan laughed silently, and he looked at the bow of the boat again. The incense on the bow had been extinguished, and then said, "Let your soldiers retreat! The time has come."

Qin Yong was very anxious. If he retreated, they would be the first army in the 20,000 training army that did not attack the city. He could not afford to lose his face.

"Master, can you give Huyi another half a stick of incense sticks? You will definitely attack the top of the city."

Zhang Xuan said lightly: "Do you want me to break the rules?"

Qin Yong had no choice but to order: "Ming Jin to withdraw his troops!"

‘Dang!Dang!Dang!’

The bell rang, and the thousand soldiers Qin used were unable to attack the city. The army retreated. This was the first army that failed to attack the city in seven days of training, and it was not able to attack the city in one stick of incense.

The soldiers sat on the shore to rest in dejectedly, Qin Yong was even more depressed, with tears in his eyes. He was extremely strong and regarded reputation as more important than his own life. But this time he not only failed, but also saw it by the coach.

Zhang Xuan could understand his mood, so he patted his shoulder and said earnestly: "Go back and summarize the reasons for the failure, and hope not to disappoint me in the real battlefield."

"I remember the humble job."

Zhang Xuan said again: "Go back and have a good rest, accumulate energy, and officially attack the city the night after tomorrow!"

Time passed day by day, and the Sui army never siegeed the city, but every day there were ships coming to harass them, beating drums and shouting, day and night, which made the Jianghuai defenders on the city very nervous every day and not having a good rest. The soldiers were extremely tired, and their defenses were more or less relaxed.

At dusk that day, dozens of tiger-teeth generals gathered in the tent of the central army of the Sui army and followed the commander's combat deployment. Everyone was extremely excited. They finally waited for the decisive battle.

In the middle of the big tent is a low table, on which are Hefei models, cities, moats and dozens of large ships carefully made by dozens of carpenters, made vividly.

At this time, Zhang Xuan coughed gently, and the big tent suddenly became silent. Zhang Xuan picked up the wooden pole and pointed to three of the slightly special big ships and said, "These three big ships cannot be seen at night, but you should all know its special features. Tonight's siege, they are the key to the victory or defeat."
