Chen Tuan was seriously injured and fled in embarrassment, and the Dongwu soldiers who were still scolding Liu Yu did not dare to speak out at this time, and only cared about putting out the fire.

Liu Yu saw that the lesson given to Chen Shu was enough, so he turned around and flew back, and the Eastern Wu soldiers watched Liu Yu leave, and they breathed a sigh of relief, they were afraid that Liu Yu would serve them in a pot.

With today's events, no one in the Eastern Wu Army will dare to pick quarrels and provoke trouble, after all, there is already a lesson from Chen Luan, and the Eastern Wu Army does not dare to easily invade Liu Yu's territory, which can be regarded as killing two birds with one stone.

On the way back, Liu Yu slowed down a little, thought a lot about the development of his army, and returned to his barracks not long after.

Liu Bei stared at the manufacturing of mecha equipment and other equipment in the army, and was worried that Liu Yu would be in danger, and when he heard the soldier report that Liu Yu had returned to the barracks unscathed, he realized that his worries were unnecessary.

Liu Yu returned to the barracks and thought for a long time, what he could do was to use the martial arts mechanism on Liu Bei and the others to improve his skills to the level of immortals.

Thinking of this, Liu Yu called Caesar.

"My lord, what do you command?" Caesar asked respectfully.

"Now that you have broken through the Blue Decision, what I want you to do is to teach them to improve their skill level and enhance their combat capabilities, you may be able to do it?" Liu Yu asked.

"The affairs of the main bus generation will definitely live up to the trust." Caesar replied that after Liu Yu explained to Caesar and Liu Bei and others, he left the barracks again.

For this kind of thing, the officers and men in the army did not feel strange, but understood more that Liu Yu was running around for the affairs of the army, and he was more attentive to the things that Liu Yu explained.

Liu Yu jumped into the air and went straight to the direction of the demon clan, if he relied on his foot strength alone, it would take a day at the earliest, but he could arrive at the fastest speed if he flew over.

In order to hide people's eyes and ears, Liu Yu hid his figure and circled close to the person who was the leader, only to see that the leader was Cao Cao.

I didn't expect him to gather several sects of the human race to attack the boundary card pass.

Behind the boundary card is the Hidden Dragon Mountain, the mountain range where the demon beasts are entrenched, but I am afraid that Cao Cao is fighting the idea of those demon beasts.

Liu Yu rushed straight to Yinlong Mountain, Cao Cao and the others were already preparing to attack the city, and he had to hurry up.

From the foot of the mountain to the mountainside, you can see all kinds of demon beasts infested, Liu Yu glanced at the direction of the boundary card pass, gathered a fireball in his hand, and then threw it towards the demon beast not far away.

Those demon beasts were not big, Liu Yu threw a few palm-sized fireballs over, and several demon beasts fell to the ground with a bang, and the smoke and dust dispersed, leaving only a charred-like demon beast corpse.

The other demon beasts originally wanted to escape, but seeing that Liu Yu had no intention of attacking again, they quickly regained their composure, eating, drinking, and strolling around, Liu Yu saw that the demon beasts were so indifferent, and simply fell into a group of demon beasts.

The fireball in his hand continued to expand, and a group of demon beasts looked at Liu Yu as if they had seen something very novel, Liu Yu looked at the demon beasts beside him, although he didn't want to kill so cruelly, but if he didn't do it, once Cao Cao succeeded in attacking the city, Hidden Dragon Mountain would be in danger.

"Boom!"

There was a loud bang, and many of the demon beasts that surrounded Liu Yu turned into charcoal, and Liu Yu made a few grimaces at the other demon beasts that had not yet returned to their senses, and then ran down the mountain.

Seeing Liu Yu so provocative, the large group of demon beasts became angry and their eyes were red, and the group of demon beasts instantly became restless and violent, chasing Liu Yu and running away.

Liu Yu saw that the demon beasts had been enraged, and they chased after him, and the ground also shook, and where the demon beasts passed, the sand and dust filled the sky, and Liu Yu couldn't help but speed up.

Even if these demon beasts are not to be feared, such a large group of demon beasts are in a state of rage, and it will be very difficult for him to really deal with it alone.

Liu Yu rushed all the way to the Jiepai Pass, and the speed of the demon beast group also increased unabated.

Cao Cao was about to attack the city, but he saw that the demon beasts not far away were rushing towards the direction of the Jiepai Pass, the dust was flying, covering the sky and the sun, and the roars of the demon beasts kept coming, and they felt a headache from afar.

Cao Cao seemed to see that the demon beast group was chasing a person, and before he could see it clearly, the figure had already disappeared out of thin air, and the demon beast group rushed straight towards Cao Cao's army.

"Fight the monsters!" Cao Cao shouted, and the soldiers who were originally preparing to attack the city immediately turned their heads and prepared to deal with the demon beast herd.

In an instant, the demon beast group and the human army rushed together, most of the demon beasts can eat people, even some vegetarian demon beasts, at this time in a berserk state, also became extremely aggressive.

The Terran army was scattered by the sudden group of demon beasts, and it became a feast for carnivorous monsters, a group of demon beasts kept biting, and demon beasts of various sizes quickly overwhelmed the Terran army.

Even when encountering the Terrans with some combat power, the demon beasts did not rush to attack, but watched the juggling while defending, and waited until the Terrans were exhausted, and then killed with a merciless blow.

Cao Cao was also busy fighting with the demon beasts, not realizing that the army had been defeated and retreating, and even the scouts who passed the war report had become a feast for the demon beast group.

After a full meal, the group of demon beasts seemed to have calmed down a lot, and the offensive gradually weakened, Liu Yu couldn't help but shake his head as he overlooked the miserable situation of Cao Cao's army on the city wall.

With a group of Terrans, he dared to gnaw on the bone of the Boundary Pai Pass, so he didn't knock his teeth?

Although Cao Cao's combat power is quite high, he can face some huge demon beasts, even if he has an advantage in speed and agility, but he is also a human race after all, and his physical consumption is not comparable to that of demon beasts.

Under the repeated attacks of the demon beasts, they kept retreating, and the human race around him was constantly killed by the demon beasts, and the blood of the demon beasts and the human race flowed on the ground, converging into a pool of blood.

The heavy smell of blood spreads, accompanied by flying sand and dust pouring into the nasal cavities, choking people almost nausea.

Liu Yu couldn't help but cover his mouth and nose, the blood flowing after the death of the demon beast would quickly become foul-smelling, mixed with the smell of human blood, many human beings couldn't help but vomit in the dark, but those demon beasts didn't react to it at all, just kept attacking.

Some of the vegetarian demon beasts have calmed down their anger and began to retreat, only some huge carnivorous demon beasts are still greedily biting the human race, the original mighty human army, at this time, under the attack of the demon beasts, the number of people has decreased rapidly.

"Get together, don't scatter, fight with all your might!" Cao Cao shouted as he struggled to deal with the demon beast.

Immediately, some soldiers approached around Cao Cao, brandishing swords to resist the demon beasts, and the defenders of Jiepai Pass watched Cao Cao's army confront the demon beasts, but they were also worried that the demon beasts would attack the city, but Cao Cao sent some people to attack the city, so they couldn't hold it at all.
