A few days later, Cao Renzheng led hundreds of guards to patrol the city of Wancheng and greeted the people cordially, and the people also felt that this new Cao City Lord was much closer than the original Zhang Xiu City Lord, and responded one after another.

"Report! Checkmate! Big things are wrong! The intelligence soldier suddenly appeared in front of Cao Ren, who was talking to people, and shouted out of breath.

"How many times have I said that you should not be afraid of danger and not panic!" Cao Ren was very tired of being interrupted from the conversation, and scolded, seeing that the intelligence soldier was still panting, thinking that there was some urgent military situation, and said, "Take a breath and speak slowly." ”

The intelligence soldier took a deep breath, stabilized his breath, and said slowly and without a tone: "Tongguan was taken by Zhang Quan. ”

"Tongguan was taken away," what a big deal, a small pass, just give him a good time, and then reacted, Cao Ren said violently: "What did you say?" Tongguan? Tongguan on the east side of Chang'an, Luoyang and Wancheng, west of it? ”

"Yes."

"What about Chang'an?" Cao Ren asked. As soon as Tongguan was captured, Chang'an's contact with them was cut off.

"The soldiers who retreated from Gutong Pass said that Chang'an was surrounded by Zhang Quan's army, and Zhong Miao was too closed to defend it." The intelligence officer said.

"Zhong Xuan? What kind of battle will a civil official fight, what about Cao Hong? Cao Ren said.

"General Cao Hong," the intelligence soldier said slowly and cautiously, "It seems that Zhang Quan was captured when he attacked the boundary of Chang'an." ”

"What!" Cao Ren stopped his irritability and instructed his own soldiers: "You guys, go to Xuchang to inform Xun Yu Zhongshu that Tongguan was taken and Chang'an was besieged, and asked him to take care of Wancheng; The rest of you will lead the army north with me to Tongguan and Chang'an. After speaking, he picked out 15,000 from the 20,000 military horses in Wancheng, and went north to Tongguan.

After marching for eight or nine days, he arrived at Tongguan, when he saw the rugged mountains and the solid and towering Tongguan, suddenly a wave of loss and regret came to his heart, and he walked too hastily, without bringing siege equipment, ordinary military horses, how could he capture this Xiongguan.

But it didn't show it, the soldiers were fast, and a lot of time had been wasted on the road, and Chang'an was likely to be captured (at this time, Chang'an had been captured for six or seven days).

Cao Ren waved his army to attack the city.

Left behind in Tongguan is Xu Shu, commanding 10,000 soldiers, there is a way to be a husband when the pass is not open, 10,000 soldiers, to defend a pass, more than enough.

Moreover, during this period, Xu Shu also carried out a semi-dragon transformation, but a pair of dragon wings shrouded in flames several meters wide were spread out behind his back, flying above Cao Renjun, the wings danced, and the fire and rain spread all over the sky.

At this moment, the scribe in the sky, who was several meters in size, seemed to Cao Renjun to be a death-like existence.

Cao Ren looked at Xu Shu flying in the sky, his eyebrows and eyes were furrowed and trembling, his left hand was clenched into a fist, and his fingers poked several blood holes in the palm, although it healed immediately, but he could see his annoyance and helplessness.

Cao Ren, he can perceive that although he is also a high-ranking half-blood, although he is also the top of a high-ranking half-breed, Xu Shu can carry out a large-scale elemental attack with a half-dragon, but the second Cao Ren cannot dragonize into dragon wings, and can only fight by strengthening muscle strength through dragon blood. It is not because Cao Ren's dragon blood ratio is lower than Xu Shu's, but because Cao Ren's dragon blood ratio is higher than Xu Shu's.

"Once the dragon is transformed, perhaps, it will remain in the form of a dragon forever, and there will never be a human again, and it will no longer be a human." Cao Ren muttered.

In the hierarchical system of the dragon half-breed. The topmost section is the pure-blooded Dragon King, with a 100% dragon blood ratio; They are the children of destiny, and they don't need to work hard; They can freely transform between a condensed human form, a powerful dragon king form, and an elegant and delicate half-dragon form; As soon as they are born, they are noble and invincible.

And a high-ranking dragon hybrid like Xu Shu, who can be transformed into a half-dragon, has a blood concentration of close to 50% but no more than 50%. After many efforts, they gradually tapped their potential and occupied the three princes and nine kings of the ruling class.

And the dragon bloodline is between 100% and 50%, like Cao Ren, there are many people born with dragons, but very few are active in the world. All their lives, they live in the contradiction of the pursuit of power and the defense of dragons; Once a dragon is transformed, it will always maintain the form of a powerful dragon; Once he retains his powerful dragon form forever, he is strangled by the powerful hybrids who proudly claim to be the ruling class of the human race.

The three types of people, just like the first, third, and second, after a few years, what people remember is either the first in a generation of Tianjiao, or the third in the top three.

······

Cao Ren's army had killed thousands of people, and there was no progress in tackling the fortifications, so they could only withdraw their troops and set up camp under the pass, and the smoke and dust in the sky diffused from the direction of Luoyang behind Cao Ren's army, followed by the chaotic roaring sound of horses' hooves. Cao Ren suddenly became alert, it could be that the enemy army was sneaking up from my rear, and shouted:

"Gathering! Get ready to meet the enemy! ”

Sure enough, it was a group of cavalry, and the leader gradually saw it clearly, Cao Hong. Cao Hong is the same generation as Cao Ren and Cao Cao, and he is Cao Ren's cousin.

Cao Hong saw that it was his cousin, his face was happy, he stopped the cavalry, and said:

"Brother, I didn't expect you to come!"

Cao Ren was a little puzzled and said, "Cao Hong? Aren't you in Chang'an, how did you lead the army from the direction of Luoyang? Uh, no, weren't you captured by Zhang Quan in Chang'an? Could it be," Cao Ren's expression became suspicious, swept towards Cao Hong, who was excited, and suddenly shouted:

"You betrayed!" As he spoke, he raised his right hand holding the weapon, and the earth and mountain dragon blood in his body boiled instantly, although Cao Ren could not hit the level of condensing the dragon wings, in Cao Hong's opinion, Cao Ren's right hand trembled, obviously he couldn't control the power of the dragon blood in his body at all, and the field of violent coercion instantly permeated the two armies.

Cao Hong panicked, waved his hand in denial, and said:

"Don't panic! Brother! Don't panic, listen to me. ”

"Say it," Cao Ren said lightly.

"I was attacked by Zhang Quan's kid outside Chang'an City, and I was arrested, and then Zhong Xuan closed Chang'an, Zhang Quan besieged the city, and then there was a lack of water and firewood in the city, Zhong Xiang abandoned the city and fled, and after Zhang Quan occupied Chang'an, he let me go." Cao Hong said briefly.

"Just let you go? It's that simple? Cao Ren said.

"yes, I don't know what that idiot Zhang Quan is thinking. Zhong Miao and I took a boat down the Yellow River and went ashore in Luoyang, and then I rectified the military horses in Luoyang City and killed Chang'an, Tongguan! Cao Hong said ambitiously.

"Zhang Quan's stupid, hum, the fool took Chang'an from you, he's a fool, what are you!" Cao Ren shouted, at this moment, he has begun to face up to and attach importance to this opponent. Cao Ren said again: "Wait, you said that Chang'an was taken by Zhang Quan a few days ago, so what am I here to do in Tongguan?" ”

"Break Tongguan and recapture Chang'an!" Cao Hong said casually, is there anything else to do?

"Break your sister!" Cao Ren shouted, swept the soldiers brought by Cao Hong, and said, "Do you know how many people it takes to build a well-defended giant city of Chang'an?" With my 15,000 soldiers and your 5,000 cavalry, without siege equipment, not a single Tongguan can be defeated! ”

"What are you going to do, brother? After Brother Meng De learned that Chang'an was lost, although the main responsibility lies with me, you who guarded Wancheng will also be jointly and severally responsible. Cao Hong said lightly, you are older than me, you can do what you say.

Cao Ren slowed down, somehow, from the time he left Wancheng, there was a vague sense of foreboding in his heart, could it be that Chang'an was lost? But at this moment, Chang'an has been lost, but that premonition has not disappeared. Gathered his mind and said:

"We definitely want to take Chang'an back, but it's not in a hurry. We are now 20,000 soldiers blocked under Tongguan City, waiting for the transfer of siege equipment from Wancheng Luoyang to recapture Tongguan Chang'an in one fell swoop! ”
