But after an hour or two, Liu Ao felt that his hands were completely unconscious.

At this time, it was already late at night, and Copper Hammer commanded his soldiers to put the demon beast in the cage, and then came over with a jar of spirits.

He handed the wine to Liu Ao and said with a smile:

"I can't see it, Brother Li Hong, you have a lot of strength. ”

Liu Ao smiled and waved his hand, his eyes showing a touch of sincere admiration.

"Let's go, go back to drinking!"

A group of soldiers were already lined up at this time, cheering and walking towards the barracks.

Tomorrow's fatigue is put aside for the time being, and they also need a moment of relaxation to relieve their tiredness.

The military camp was flat in the valley, and Liu Ao swept around without a trace, but he couldn't tell where it was used for detention.

Piles of bonfires burned red, and Copper Hammer beckoned his ten squadron leaders to come over for a drink and discuss tomorrow's mission by the way.

I heard them say that tomorrow their squadron will take turns to observe the movements of the demon clan on the plain twenty miles away from the gap.

Such a task is to gain insight into the actions of the demon clan in advance, and once the demon clan attacks, it can buy time for the entire defense line of the Burial God Valley to prepare for battle.

This mission, and the most dangerous mission, each squadron will have a good night of relaxation before each departure.

After all, once there is a situation, they will be the first to fight the demon clan, often with less to more, with heavy casualties.

After more than an hour, most of the soldiers under the command of the bronze hammer had fallen asleep, and a few of them began to cultivate cross-legged.

The copper hammer took Liu Ao and whispered as he walked through the camp:

"I know that the disciples of your Jiuding Academy are assessed according to the number of demons killed, but tomorrow's mission is very dangerous, so you should stay in the defense line. ”

Liu Ao nodded while observing the surroundings:

"Where is this?"

Dozens of caves have been carved out on the cliffs on both sides of the canyon, and the entrance to the caves is guarded by soldiers.

Copper Hammer snorted coldly, "There are some demon clans imprisoned here, and some traitors in our demon army. ”

The brass hammer checked all the animal cages before turning around and walking towards the camp, "It's going to leave at dawn, I'm going to rest, and you should rest early." ”

Liu Ao nodded and got into his tent.

Soon, there were cries of voice all around.

Liu Ao also quickly fell into cultivation.

It must be very difficult to rescue Li Wu, and Liu Ao must remain in his heyday to be successful.

As soon as it was light, the camp was already bustling.

When Liu Ao walked out of the tent, he saw that the surrounding area had become an open space, and the tents had been put away by the soldiers, who were already checking their equipment and preparing to set off in formation.

Unlike the light-hearted pleasure of drinking last night, the faces of the thousand people were full of seriousness written on their faces at this time.

The copper hammer checked the situation of the team, said hello to Liu Ao and led the team to set off, and soon only Liu Ao himself was left in this camp.

After being in a daze for a moment, there was a sudden sound of footsteps behind him.

Liu Ao looked back and saw that the person who came was actually Lei Chong.

This short-tempered captain with a knife-mouthed tofu heart actually had red circles under his eyes at this time.

"Every time they go on a mission on the plains, I get scared. ”

Lei Chong sighed, and his face returned to indifference.

"The main place for your Jiuding Academy disciples to experience this time is Hongmen Pass, and we already know what happened there. ”

Liu Ao nodded, but he didn't understand why Lei Chong mentioned this matter to himself.

"I just got the news that the demon clan team was all killed by General Jin Zhiyuan and the elders of your Jiuding Academy, but their leader fled. ”

Lei Chong's eyes lit up, "The headquarters has sent an elite team to chase and kill. ”

Seeing Liu Ao's puzzled face, Lei Chong said calmly:

"Do you know why I'm talking to you?"

Liu Ao hugged his fists, "Please advise." ”

"The fact that the leader of the demon clan was able to escape the pursuit of General Jin shows that he knows the route very well, and even planned the escape route a long time ago. ”

"In other words, there are inner ghosts who have passed the escape route to the demon clan. ”

Lei Chong stared at Liu Ao closely, his gaze gradually becoming cold, "Before you find out the inner ghost, you people from Jiuding Academy are also suspicious." ”

Instead of being angry, Liu Ao nodded in agreement, and said worriedly:

"If that's the case, then it's very likely that the inner ghost will also pass on more information to the demon clan, presumably now all defense lines and defense areas have been strengthened. ”

A touch of surprise flashed in Lei Chong's eyes, this kid named Li Hong was so calm?

"Someone," Lei Chong beckoned to the two soldiers, "don't restrict his freedom, you just follow him." ”

Liu Ao's heart sank, someone followed him, how could he save Li Wu?

It seems that we can only continue to wait for the opportunity.

Helpless, Liu Ao could only return to his tent to cultivate.

The two soldiers were standing on the edge of the tent, and Liu Ao couldn't sneak out without being discovered.

The next morning, there was a sudden noise in the barracks.

Liu Ao got up and lifted the tent and asked the two soldiers guarding it:

"What's wrong?"

The two of them looked impatient, and they should have wanted to leave, but due to Lei Chong's order, they could only stay here.

"Something happened to the Copper Hammer Squadron!"

One of the soldiers was full of anxiety, "There was news just now, there is a big demon leading 50,000 demon soldiers towards our defense area, Captain Copper Hammer and they are outnumbered, and now they are surrounded. ”

Liu Ao's eyes lit up, "Then what are you waiting for, let's hurry up and help." ”

"No!" one soldier clenched his fists, "the captain said that you can only move within the defensive line. ”

Liu Ao's eyes widened, "When is it, if you don't go, I'll go by myself!"

After speaking, Liu Ao pushed the two away and ran away quickly.

The two soldiers were so anxious that they hurriedly followed.

At this time, the entire defense zone became tense.

The squads were already waiting in their respective defense areas, and more people were rushing to the gap under the leadership of the squad leader.

Liu Ao ran wildly while looking up at the colorful light curtain over the defense area.

It was a defensive formation at the gap, and once it was activated, it would require the consumption of a huge amount of spirit stones, which meant that the demon army was already very close.

"Team Five, follow me to the west!"

"Hurry up, hurry up, don't rub Lao Tzu!"

A squadron leader ran past with thousands of men in full steps, shaking the ground and trembling.

Lei Chong came to the middle of the gap at this time, he was dressed in pitch-black armor, with a blood-red cloak behind him, and a pitch-black spear in his hand shining coldly.

But seeing that he was condensed, he roared in a low voice, "Everyone, find a good position as quickly as possible, and listen to my orders!"

After a few moments, the entire gap had fallen completely silent, except for heavy, tense gasps.

Thousands of people lined up at the gap, and the high ground on both sides was also full of soldiers, and the cloud-piercing arrows in their hands were already full, aiming at the empty plain ahead.

Several formation mages were covered in sweat and trembling, obviously trying their best to maintain the defensive formation.

Liu Ao stood on the high ground and looked into the distance.

The distance was empty, and a gust of wind and sand blew, rolling up the dust.

A breath of slaughter is coming!

Lei Chong stood at the front of the line and suddenly shouted:

"Giant cloud-piercing arrow, test shot!"

In the next moment, I saw a ten-zhang giant crossbow erected on a high place being filled with all the strength of dozens of soldiers.

A thigh-thick, three-zhang long cloud-piercing arrow shines brightly.

"Put!"

As soon as the order was given, I saw that this giant arrow cut through the sky, dragging a long aura tail, and appeared thousands of feet away in the blink of an eye.

The arrows began to fall, slamming into the ground.

"Bang!"

A violent explosion sounded, and the ground cracked violently, and an earthworm beast roared out of the ground.

It squirmed, and its body was pierced by the arrow, flowing green blood, and it fell to the ground with a bang after a few struggles.

Seeing this scene, Lei Chong's face changed greatly.

"Be vigilant and watch out for the ground!"

As soon as the words fell, I saw that the ground less than thirty zhang in front of the gap suddenly exploded, and ten earthworm beasts drilled out of the ground, and their mouths instantly spit out green acid, covering the demon suppression army column.

"Stand back!"

Lei Chong gave an order, and thousands of soldiers retreated neatly, shrouded in the formation.

"Sting~"

The highly corrosive acid fell on the formation, and a large cloud of green smoke instantly came out.

Several formation mages turned pale and roared angrily:

"Kill them, don't let the formation be corroded!"

Lei Chong rushed out, and behind him, several squadron leaders sprinted at full speed and launched an attack on a earthworm beast.

But at this moment, there was a roar from the ground.

Among the holes drilled out by the earthworm beasts, one after another firescale crocodiles came out.

They were more than three feet long, covered in golden scales, and had flames burning from their bodies.

The blood basin full of sharp teeth swallowed flames, and instantly caused the heat wave of the entire defense zone to roll.

In the blink of an eye, hundreds of fire-scaled crocodiles came out and roared towards the Demon Suppression Army.

Lei Chong blasted an earthworm beast and turned back sharply and roared:

"Ice Array!"

Several formation mages clenched their teeth, and as soon as their gestures changed, they saw a chill emerge from the entire defensive formation.

The surrounding aura was constantly being extracted, and the formation began to be covered with a layer of ice.

At this time, the soldiers of the Demon Suppression Army at the front had already rushed towards the firescale crocodile.

But the firescale crocodiles are known for their rough skin and thick flesh, not to mention ordinary swords, even cloud-piercing arrows are difficult to pierce the golden scales on their bodies.

In just one photo, hundreds of soldiers were knocked away by the firescale crocodile, and the flames on the firescale crocodile instantly engulfed these soldiers.

The screams were heard, and the hearts and ears trembled when they heard it.

Liu Ao frowned, it seems that this battle is not easy to fight.

Fortunately, the formation change was successful.

Countless cold air continued to overflow, instantly freezing the ground hundreds of feet in front of the gap.

With the naked eye, it can be seen that the bodies of these golden-scaled crocodiles are covered with a layer of ice, and their movements have slowed down.

But that wasn't enough to limit their movements.

Lei Chong jumped high, his body fell upside down, and the black spear in his hand burst into spiritual light, instantly piercing the head of a golden-scaled crocodile.

Dozens of giant cloud-piercing crossbows aimed at the fire-scaled crocodile, firing arrows one after another.

But at this moment, there was a rumbling sound in the distance.

The ground began to shake violently.

Liu Ao stood on a high place and couldn't help but squint his eyes.

The horizon in the distance shimmered with gold, like a sea of golden fire.

This is a demon army composed entirely of fire-scaled crocodiles, looking at the number, it definitely exceeds 50,000!

You must know that the total strength of the gap defense area is only 10,000!

At this moment, there was movement in the canyon behind him, and two teams of thousands of people rushed to him.

They hurried to the gap and lined up neatly.

This is the defense line of the Valley of the Buried Gods, the Demon Army Brigade of the two adjacent defense areas, and they came with most of the soldiers as soon as they received Lei Chong's request for help.

In the distance of the canyon, there are still teams rushing in.

Lei Chong had already killed the red eye, killed the last firescale crocodile nearby, looked at the hundreds of soldiers who died tragically on the ground, and then looked at the army of firescale crocodiles that had come hundreds of feet away, and roared:

"Everyone obeys the order, a group of 100 people, disperse!"

As soon as the words fell, tens of thousands of soldiers behind him turned into more than a hundred squads and dispersed.

"Cloud piercing arrow, release!"

On the high ground, thousands of soldiers immediately let go, and the cloud-piercing arrows that had long been ready to be fired shot into the sky, like a rain of arrows, slashing the sky and enveloping the army of firescale crocodiles.

But when the cloud-piercing arrows landed on the fire-scaled crocodiles, they were instantly bounced away, and occasionally the cloud-piercing arrows pierced their bodies, and they were quickly burned to ashes by the flames.

Liu Ao's pupils shrank, if there was no other way to deal with it, I am afraid it would be difficult to resist this army of fire-scaled crocodiles with extremely strong defense!
