On the city wall, the guards who were fighting with the fierce beasts heard the movement, forced their opponents back, and looked over.

After seeing Lu Yuan and Tracy, who were quickly killing the fierce beast and approaching the city wall, everyone was stunned for a moment, and then showed a surprised smile.

"It's ...... Reinforcements?! Reinforcements are coming?? ”

"That's a lot of mechanical life! It's so strong, it can kill a few fierce beasts with one shot! ”

"The one in front is Zhanzun, right?? It's great that a strong Zhan Zun is here! ”

"Quick! If we join forces with them, we should be able to kill all the beasts here! ”

"That's right! Kill all these brutes! ”

The two young guards on the city wall, one is a guardian warrior and the other is an elemental warrior, they are both cadets of the genius battalion, and they are teaming up to kill the enemy.

After seeing the edge of the land in the distance, the two of them were stunned and glanced at each other.

"It's Lu Yuan's junior?! How did he end up here? ”

"Those mechanical lords, it seems that they are the mechanical lords in the El mechanical ruins, controlled by the Lu Yuan juniors? Better! ”

Seeing that the more than two hundred mechanical lords beside Lu Yuan continued to send out spiritual power cannons, both of them widened their eyes and showed a look of shock.

And Lu Yuan, who was in the group of fierce beasts, was controlling the mechanical lord to kill the fierce beasts that pounced at the moment, and he was a little surprised in his heart.

After coming to this area, there were indeed many alienated beasts, and after killing these alienated beasts, Lu Yuan once again absorbed a lot of unknown aura.

The cube also shook again.

Tracy's strength is very strong, coupled with more than two hundred mechanical lords, there is almost no enemy among the fierce beasts outside the walls of the northern district.

They thrust their knives into the horde of beasts and move towards the walls.

In just over ten minutes, the two of them came to the foot of the mountain, and then climbed towards the mountain peak while killing the fierce beast.

Like Camp 257, the corpses of the beasts at the foot of the mountain were piled up, and the blood on the hillside stained the ground red, and the strong smell of blood overflowed.

Tracy charged at the front, with a group of Machine Lords answering on the flank, and also breaking in the rear, with a clear distribution.

Soon they went up the mountain and under the city walls.

Afterwards, Tracy, Lurim, and the other Machine Lords took to the skies and jumped onto the walls.

More than two hundred Machine Lords landed on the city wall, causing the city wall to shake.

A ten-meter-tall steel body is not light.

As soon as they reached the city walls, Tracy and Lu Yuan's gaze swept over the walls and inside the city.

At this moment, many fierce beasts are on the city wall, and a group of melee guards are fighting with the fierce beasts on the city wall, protecting the long-range guards.

The ranged guards continued to slay the beasts beneath the walls.

In addition, some fierce beasts also entered the city wall, and the sound of battle sounded inside.

Tracy and Lu Yuan glanced at each other, and Lu Yuan spoke:

"Deputy Commander Tracy, I'll help kill the fierce beasts on the city wall first, and then resist the fierce beasts outside the city, and the fierce beasts in the city will trouble you."

Tracy smiled slightly, her spiritual power surged, and her long red hair flew in the wind:

"Leave it to me."

Her body turned into an afterimage and rushed towards the city.

And Lu Yuan's mind moved, and he controlled the mechanical lord to spread across the city wall.

A guard armed with a heavy sword is fighting a third-order gibbon.

As a defensive camp closer to the border defenses, the average strength of the guards in the 306th Guard Legion is much stronger than that of the 257th Legion.

Even the guards of the third order are more than the number 257.

At this moment, this guard is a third-order.

The two sides fought back and forth, and the guards' heavy swords and iron gibbon's fists collided together, making a sound of gold and iron.

The gibbon let out a roar.

At this moment, a psionic cannon with powerful spiritual power fluctuations landed on the gibbon's head.

Rumble!!

The gibbon's head was directly pierced, and its huge body, which was more than five meters tall, shook and slowly fell to the ground.

The guards were stunned for a moment, and looked in the direction where the psionic cannon was coming from.

He saw the mechanical lord slowly running past him with heavy steps, and one after another psionic cannons shot towards the beast.

As long as it is not a fierce beast above the third-order leader level, it will basically be killed with one shot.

This is not just a mechanical lord, dozens of mechanical lords ran past him, killed the fierce beasts when they encountered them, and in a short period of time, all the fierce beasts on the entire city wall were almost eliminated.

There are only a few fierce beasts above the third-order boss level who are fighting with the mechanical lord.

The guards found that not only him, but the other guards who had no opponents were also confused.

The beasts were cleared so quickly that they didn't know what they were going to do for a while.

Soon, one by one, the third-order leader-level fierce beasts were besieged by several mechanical lords and high-ranking guards at the regimental commander level.

The top brass of the guards were also liberated one after another at this moment.

After a middle-aged man killed a third-order leader-level earth fire python with the help of nearly ten mechanical lords, he took a deep look at the huge mechanical lord, and then his gaze swept around, and roared:

"All those who are free, don't be stunned! What should be guarded by the side of the ranged warrior is guarded by the side of the ranged warrior! The rest of the people went to the city and other areas to help their comrades!! ”

Hearing this, the guards, who had lost their opponents, came back to their senses.

Many of the ranged soldiers who were originally guarded by the guards were not dead at the moment, so they naturally stayed by their comrades.

The dead guards glanced at the corpses of their comrades with red eyes, and then ran in the direction of the other walls with a roar.

Lu Yuan controlled the Machine Lord, and at this moment, several guards came to his side, with a look of gratitude in their eyes.

"This little brother, which camp are you from?"

A middle-aged man asked.

Lu Yuan smiled: "I'm from Camp 257...... Well, the head of the Mechanical Legion, Lu Yuan. ”

Lu Yuan originally wanted to say that he was the vanguard, but it seems that now Luo Xiu has opened a mechanical legion, so he reported his own legion name.

"The Mechanical Legion?"

Several people were stunned and looked at each other a little blankly.

The configuration of the defensive camps is basically the same, and they don't have any mechanical legions in Camp 306.

What the hell is the mechanical legion of 257?

Seeing that a few people seemed to be a little confused, Lu Yuan explained:

"These mechanical lords are all my warriors, so Captain Luo Xiu set up a mechanical legion specifically for me."

Hearing this, several people's pupils shrank, and they glanced at more than two hundred mechanical lords with a look of surprise in their eyes.

"All of these Machine Lords are yours alone?"

The middle-aged man asked in shock.

Originally, he thought that this was the killer weapon of which defense camp, but he didn't expect that it was all Lu Yuan's alone.

Lu Yuan nodded: "Hmm." ”

He smiled and said, "Commander Luo Xiu received a call for help from the 306 defense camp, so he ordered me and Deputy Commander Tracy to come to support. More than 200 of my Mechanical Lords will help you slay the beasts. ”

There was surprise in everyone's eyes.

"I see! Then thank you Captain Luyuan! ”

Although Lu Yuan looked very young, which made them a little confused, but now that they were reinforcements, they wouldn't ask much.

At this moment, the Machine Lord had already branched out all over the entire northern city wall, and after cleaning up the fierce beasts on the city wall, the Machine Lord still aimed the psionic cannon at the fierce beast group outside the city wall.

The roar of the psionic cannon continued to sound, and the terrifying power erupted.

After the addition of the firepower of these mechanical lords, the group of fierce beasts that had already arrived in the city was repulsed almost in a short time.

After leaving behind a large number of corpses, the herd was driven back to the bottom of the mountain.

The pressure on the northern wall suddenly became much less.

All the guards of the northern city wall were a little incredulous, they didn't expect this menacing group of fierce beasts to be repelled so easily.

Originally, the beasts had already entered the city!

The middle-aged man, who was a high-ranking member of the guards, was a little shaken.

"What a lot of firepower!"

The firepower of these two hundred or so second-order consummation-level mechanical lords was stronger than that of all the ranged warriors in the northern city wall combined.

After suppressing the tide of fierce beasts, Lu Yuan smiled at the middle-aged man who was a little stunned:

"The northern wall defense line will not be much of a threat for the time being, I will leave twenty mechanical lords to help you suppress the tide of fierce beasts, and then I will go to other places to support."

Hearing this, the middle-aged man and several high-ranking guards on the side were all in awe, and saluted Lu Yuan:

"Thank you, Army Commander!"

Lu Yuan returned a military salute: "Yes." ”

His heart is also quite beautiful, after all, he has absorbed a lot of unknown breath.

Lu Yuan felt that it was not far from the transformation of the evolutionary cube.

Continue.

He led a large number of mechanical lords and ran in the direction of the other city walls.

…………

Southern city walls.

After summoning the Frost Giant, Si Tingxue continued to resist the tide of fierce beasts.

Beneath the walls of the city where she stood, almost all of the beasts were frozen into ice sculptures and then destroyed into powder.

In the entire city wall, there is only her area, and there are no fierce beast soldiers under the city.

In other areas, many fierce beasts have already climbed the walls.

Si Tingxue not only needs to deal with the fierce beasts under the city wall, but also needs to help others kill the fierce beasts on the nearby city wall, even she feels a little tired at the moment.

The beast tide lasted for a day and a night, except for the beginning, when she rested for a while, and then almost for a night, she did not rest.

Although she used various potions to maintain her condition, she still felt tired mentally.

At this moment, Si Tingxue heard a roar from the other side, her eyebrows furrowed slightly, and she looked in the direction of the northern defense line.

Could it be that there are more fierce beasts over there?

Si Tingxue's face was ugly, and he glanced at the direction of the sky, and now only Ye Zhenghao can break the game.

With the addition of the Frost Giant, in just a few minutes, Ye Zhenghao had already gained the upper hand.

The demonic monitor lizard's body was already covered with scars, and it wouldn't be long before it would be killed by Ye Zhenghao.

There was only one blue rat left, and it couldn't make any waves.

In that case, it would be worth it for her to use the Frost Giant Summoning Stone.

At this moment, a huge mechanical lord suddenly ran from both sides of the city wall and came to the southern city wall.

The Machine Lord slew all the beasts on the city wall along the way, and soon, the originally chaotic city wall is now in some order.

Seeing this scene, Si Tingxue's eyes widened slightly, and a trace of consternation appeared on her cold little face.

"It's ......"

At this moment, Si Tingxue saw a person who should never have appeared here, and the shock on his face was even worse.

"Lu Yuan?"

The land edge came to the southern wall.

After all, compared to the other three city walls, the southern wall was facing the Endless Mountain Range, and the number of fierce beasts encountered was definitely the largest, and the pressure was also the greatest, and they needed help the most.

Of course, there is another reason that the number of fierce beasts is the largest, and the number of alienated fierce beasts is naturally the largest, and the number of unknown beasts that can absorb the unknown breath is naturally the most.

As a result, Lu Yuan left twenty Mechanical Lords on both the eastern and western walls, and brought other Mechanical Lords with him.

As soon as he came to the southern city wall, Lu Yuan found that this side was colder than other places, and he saw at a glance that on the edge of the city wall, Si Tingxue stood out from the crowd.

Lu Yuan found that Si Tingxue seemed to see him as well, and his face even changed slightly.

Lu Yuan smiled in his heart, he had known Si Tingxue for a month, and it was the first time he had seen Si Tingxue have such a big change in expression.

Well...... The widening of the eyes was a little wider than before.

Lu Yuan led the Machine Lord to kill the beasts on the city wall and walked over.

Soon, Lu Yuan came to the edge of Si Tingxue.

He smiled and said:

"Si Tingxue, what a coincidence."

Si Tingxue glanced at a large number of mechanical lords who were attacking the fierce beasts, and her eyes flickered slightly:

"You brought these from the El Machine Ruins?"

Lu Yuan smiled:

"It's worthy of Si Tingxue, it's really ice and snow smart."

Si Tingxue nodded slightly: "Well, I know." ”

Lu Yuan: "......"

The corners of his mouth twitched, why didn't he find this guy so narcissistic before?

He glanced at the ice sculptures and frost powder below Si Tingxue, and there was not a single fierce beast within a radius of hundreds of meters, all the fierce beasts that entered this realm were frozen into ice sculptures without running a few steps, and then shattered, and couldn't help but shrink their pupils slightly.

Although Si Tingxue seems to be a little narcissistic, she does have narcissistic capital.

Lu Yuan ordered the Machine Lords to disperse, and after killing all the beasts on the walls, they began to attack the beasts outside the walls.

After the addition of nearly two hundred mechanical lords, the fierce beasts that had been constantly rushing up the city wall were gradually pressed back.

Si Tingxue also saw this scene.

Her eyes flickered slightly, and she asked with some curiosity:

"Why are you at Camp 306?"

Lu Yuan said with a smile: "I am now the commander of the mechanical corps of Camp 257, and I was ordered by the commander of the No. 257 legion to come to support you, I am considered a reinforcement." ”

Si Tingxue opened her small mouth and looked at Lu Yuan with a hint of surprise in her eyes.

"Captain of the Mech Corps?"

Lu Yuan grinned: "These mechanical lords are all my soldiers, look at this firepower, what's wrong with me setting up a mechanical legion alone?" ”

Si Tingxue fell silent and couldn't refute it.

The person in front of him is my sister's student, and now he has his own legion.

Obviously, he doesn't have a legion.

Thinking of this, the aura around Si Tingxue's body became a little colder, and one after another ice spears shot at the fierce beasts in the distance, killing the fierce beasts with great power, and even the ice mist spread even farther.

Lu Yuan looked at Si Tingxue, who was suddenly furious, a little confused.

What's wrong with this woman?

What's wrong all of a sudden?

Isn't this afraid of spiritual power consumption?

After all, Si Tingxue is not him, and he can absorb spirit crystals so quickly.
