Moreover, after Zang Ba's army was completely annihilated, the Qingzhou army had no troops stationed in Taishan, Luguo and other counties, and Cao's army naturally took over the above counties, and finally Yanzhou also fell into the hands of Cao Cao.

After Guo Jia's operation, Cao Cao can be regarded as completely controlling the three states of Yanzhou, Yuzhou, and Xuzhou, and still expanding a lot of territories, and there is also Jizhou, where the situation is uncertain.

Zhao Yun's Linqu victory, although it failed to completely defeat the main force of the Cao army led by Guo Jia, and failed to recover the lost territories such as Langxie and Taishan, but after all, the crisis in Qingzhou was solved, so that the situation in Qingzhou did not continue to deteriorate.

After Zhao Yun left, Chen Zhi felt that his troops were insufficient, so he did not continue to attack Cao Cao's camp, but retreated to Ganling City, assisted Yuan Tan in defense, and waited for Chang'an to send reinforcements again.

Soon, the news of Zhao Yun's defeat of Guo Jia in Linqu came, and the Qingzhou army was hit by a series of defeats to the point that it had no morale, and finally recovered.

Cao Cao also quickly got the news of Guo Jia's defeat, especially when he heard that several new types of firearms had appeared in the hands of the Central Army, which were extremely powerful.

Cao Cao wondered why it was always Lu Bu's side that researched so many weapons that were ahead of others first.

Fortunately, Guo Jia had eliminated the main force of the Qingzhou Army of 100,000 people before the defeat in Linqu, and recovered a large area of territory from the Qingzhou Army, which could be regarded as a gain and a loss.

Moreover, Liao Hua's rebellion will reveal a lot of secrets of the Central Army to Cao Cao's side, which is also a great benefit.

Now that the battle situation on the Qingzhou side has been decided, even if the containment task on his side is successfully completed, the lone army is too far deep, and it is very dangerous.

In particular, the Central Army is the best at outflanking and encircling, and it is better to withdraw to Dongjun as soon as possible, so that you can be sure.

He said hello to Yuan Shang and began to withdraw his troops.

Although Yuan Shang was unwilling, he was alone, and since he had already sent someone under the fence, he had to listen to Cao Cao.

Cao Cao's army was to withdraw directly to the south of the Yellow River, which meant that Yuan Shang's territory such as Wei County and Zhao State in Jizhou was gone.

Yuan Shang himself couldn't hold these places, so he had to send someone to Yecheng to pick up his family, and he followed Cao Cao's actions closely.

Hearing that Cao Cao and Yuan Shang's combined forces had begun to withdraw, Chen Zhi sent scouts to follow and investigate.

Seeing that Cao's army really began to withdraw, he and Yuan Tan led the army to pursue and harass, in short, so that they could not withdraw too happily.

As far as Cao Cao retreated, Chen Zhi followed up as far as he could, and the forces of the two sides were equal, and neither of them would fight a decisive battle, and no one could help anyone.

Just when Cao Cao finally withdrew to the bank of the Yellow River and began to organize ships to begin transshipment to the south bank of the Yellow River, a huge fleet of sailors came from the west.

The swift Mengchong warship opened the way in front, followed by tall fighting ships and even taller building ships, the white sails on which they covered the sky and the sun, and it was not spectacular.

On the mast of the warship, the military flag of the Central Army and the banner of the Han Dynasty were hung high, and it turned out to be the naval army of the Central Army.

The scale of this naval fleet was much larger than that of the Battle of Shaanxi, with nearly 100 ships in Mengchong and more than 100 fighting ships.

What's even more terrifying is that there are fifteen huge three-story ships, followed by huge transport ships that cannot be seen at a glance.

Fortunately, Cao Cao had been prepared, and he quietly installed four thick barrage cables in the upstream direction of Cangting Ferry.

Seeing that the sailors of the Central Army had indeed arrived as scheduled, Cao Cao secretly called for luck, urging his subordinates to speed up the speed of crossing the river, while watching the sailors of the Central Army to see how they could break the barrage cable.

Meng Chong, who rushed to the front, soon discovered the barrage in the water, and they waved the flag to stop the advance of the sailor fleet.

The tall fighting ships and building ships lowered their anchors one after another, stopped the momentum of going down the river, and lowered the mainsails.

Then out of the fleet of sailors, two fighting ships sailed out, and they slowly moved forward, and docked in front of the barrage, with the iron rope on the bow.

The sailors of the ship brought a tall furnace out of the cabin, like a blacksmith's furnace for making weapons, and a raging fire rose in it.

Then a tall winch was erected in the bow of the ship, and then the thick barrage was wrenched out of the water.

A section of it is placed in a furnace and burned for a while, slowly melting the iron cable with the help of the furnace's high temperature.

Although some time was wasted, it was very effective, and the two ships operated at the same time, fusing the iron cable into three parts.

When Cao Cao saw it, he secretly slapped his thigh, but the Central Army was really powerful, and he had already prepared.

In fact, this method was already prepared as early as when Lu Bu thought of the method of barriking the river with iron cables.

Cao Cao saw that his barrage could not stop the naval fleet of the Central Army, and he was also anxious, and he hurriedly ordered his subordinates to speed up the speed of crossing the river.

Even the raft and door panels were used, striving to send more of his subordinates across the Yellow River in the shortest possible time.

Finally, the Central Army fused four barrage cables, and the fast Meng Chong took the lead and rushed towards the Cao army who was still crossing the river at high speed.

Cao Cao and Yuan Shang had already crossed the river with the vanguard, and through their efforts, most of the men and horses of the coalition army had already crossed the river, and it was the rearguard troops of the coalition army who were crossing the river.

They needed to constantly face the attacks of Chen Zhi and Yuan Tan, so they walked in the end.

Several Mengchong boats sped up, rushed through the short passage of miles between the barrage and the ferry, and crashed into the ferry.

The ship that was hit either capsized or sank quickly in a large amount of water, and the coalition soldiers on board fell into the water one after another, struggling.

Immediately after that, more fighting ships and Meng Chong rushed over, and the second deck of the fighting ships was already full of crossbowmen, and the ballistas and repeaters began to shoot blankly.

Seeing this scene, Cao Cao decisively abandoned the rearguard troops who had not yet crossed the river and were crossing the river, and the whole army quickly withdrew south, away from the ferry and the river bank.

After easily controlling this section of the river, the ships of the naval division of the Central Army first sent naval assault brigades to the north and south banks.

They changed boats from building boats and fighting boats, rushed to the riverbank, and landed on the banks of the Yellow River as fast as they could, quickly clearing out the remnants of the enemy on the riverbank, and extending several miles in the north-south direction to establish a cordon.

The assault brigade on the north bank quickly got in touch with the scouts of Chen Zhi and Yuan Tan's army, and when they learned that Chang'an's reinforcements had arrived by water, Chen Zhi was very excited, and hurriedly rushed to the shore with Yuan Tan and his personal guards to greet his comrades from afar.

The transports that followed the fleet of sailors approached at this time, anchored at the ferry and other places where the draft permitted, set up their gangplanks on the river bank or pier, and began to land.

The engineers of the navy also urgently built a simple trestle bridge on the shore to help the transport ship, and unloaded the central officers and soldiers and their equipment on board to the north bank of the Yellow River.

This time, Lü Bu transported all the reinforcements of the Central Army directly to Qingzhou with the water army, because the entire Yellow River waterway was under the control of the Central Army's water division.

Water transportation not only alleviates the fatigue of the army's long-distance trek, but also increases the speed and avoids the obstacles of the mountains, which has many benefits.

The Central Army sent a large number of reinforcements in the direction of Qingzhou this time, and all the troops boarded the ship from different embarkation places, gradually concentrating along the way, and together they reached Qingzhou.
