The valley has become a mess!

Fierce gunfire came and went, and the strange and terrible hissing sound was endless, and from time to time there were special service officers screaming and falling to the ground.

In the sky, black bats were flying everywhere, like a rapidly surging dark cloud, constantly approaching the mouth of the pit.

Dozens of small drones patrolling in the sky were destroyed by this group of bats almost instantly, and the corpses of the casualties fell from the sky together.

The two helicopters were also forced to rise high into the air to avoid being crashed into the cabin by these crazy bats, resulting in the destruction of the planes and the death of the planes.

The guards in the valley shouted in amazement, raising their guns to shoot at the bats in the sky. With the extremely fierce gunfire, a large number of bats were shot down, like a black rain.

However, there are too many bats to kill!

Moreover, those bats are small and fly fast, and the blind strafing of the ground guards alone cannot stop them from advancing!

Just as the bat army attacked near the mouth of the pit, a bright red light suddenly released from the circle of silver metal rods erected at the edge of the pit.

Each metal rod emitted several red laser beams, and those laser beams intertwined with each other, forming a tightly guarded optical network barrier in an instant.

The first batch of bats rushed over crashed into the red light mesh barrier, and after a loud sound, all of them were burned into puffs of black smoke.

Not a single bat could fly past that barrier of light!

The bats were so crazy that after the first batch of bats were all dead, the second group of bats rushed over without knowing whether they were alive or dead.

At this moment, a mournful sound of bone flutes sounded in the valley.

After the sound of the bone flute, a large group of black skeletons suddenly rushed out from the peaks around the valley!

Each of those skeletons was more than a meter tall, no different from the height of a normal adult, and looked terrifying. Their scrawny bodies were swarthy and metallic, as if every bone was made of black iron. They seem to be alive, all of them are extremely agile and fast.

Driven by the sound of bone flutes, these black skeletons, from different directions in all directions, like locusts passing through, frantically rushed towards the light network barrier near the mouth of the pit.

The guards in the valley screamed in fright when they saw this group of weird and terrifying black skeletons.

In a panic, the guards raised their guns and fired at the skeletons, but after the bullets hit the skeletons, they only made a thumping sound, but it did not stop the skeletons from advancing.

A small number of skeletons fell apart under heavy gunfire, and some skeletons were shot by bullets that broke their ribs or arm strands, but as long as the skeletons were not falling apart, they all charged towards the mouth of the pit in a frenzy.

They were extremely fast, and in just a few minutes, they rushed to the vicinity of the optical mesh barrier at the mouth of the pit.

At this time, the sound of the bone flute in the valley suddenly changed, and the sound became short and intense.

When the skeletons heard the sound of the flute, they immediately formed a group of three or five and pounced on the silver metal rods that were closest to them.

Despite the fact that these skeletons are lifeless, under the command of the flute, they attack like well-trained soldiers, and they attack with ferocity and strategy.

The first skeleton to rush at the metal rod was sent to death, and it didn't care about anything, but just hit the silver metal rod.

As soon as it hit the metal rod, it was blown off by the laser beam fired by the metal rod. However, at this moment, the second skeleton had already rushed up.

Metal rods can automatically shoot laser beams to attack, but each attack consumes energy, and there is a time gap of a second or two.

It was this short interval of one or two seconds that gave those skeletons a chance!

The second skeleton managed to knock the metal rod stuck in the ground crooked before it could be exploded. By the time the third skeleton rushed forward, the rod was almost knocked over and damaged to some extent.

In this way, under the repeated impact of these lifeless skeletons, metal rods began to be knocked down and destroyed.

As the metal rods fell to the ground, the powerful optical mesh barrier began to appear one after another. The remaining skeletons began to quickly converge towards the gap and rush into the pit.

The guards in the valley were all shocked when they saw this.

"Plug those gaps!"

They shouted anxiously, desperately running towards the breaches, and firing at the skeletons as they tried to rush into the breaches.

Their blocking helped somewhat, but the skeletons were so fast that many of them had already rushed into the pit before the large number of guards arrived.

When Ouyang Jue, who was at the bottom of the pit, knew about the situation, a large number of bats and skeletons had already rushed into the pit.

Suddenly there was a loud gunfire in the pit, and the metal rods all over the pit also lit up with red light, forming a network of light barriers.

"Professor Ouyang, what should we do? These things rushing in are all monsters who don't know whether they are alive or dead! Moreover, there are too many of them!"

One of the agents shouted anxiously.

"Calm down, what's the panic? There are several lines of defense in our mine, and the guards are much larger than in the valley, and it is not so easy for them to rush to the bottom of the pit!"

Ouyang Jue said calmly.

At this time, Xin Ning and the others also jumped out of the excavation pit and came to Ouyang Jue's side.

They only knew that there was an enemy attacking at the top of the pit, and the battle was fierce, but they did not know the specific situation.

"Boss, what's the situation?"

Xin Ning asked.

"That old monster from the Skull Gate has brought in a large group of black iron skeletons and blood-devouring bats, and is trying to force their way in!"

Ouyang Jue said.

"Is it the deadwood Taoist who I didn't catch today and was run away by him?"

Hutu asked.

"Yes, that's him! He also did the last Dongjin Group vault robbery!"

Ouyang Jue nodded.

"Grass, this old bastard, I have to kill him this time!"

Hutu roared and flew towards the top of the pit.

Xin Ning and Kong Jie also wanted to rush to reinforcements, but they were stopped by Ouyang Jue.

"Don't be presumptuous, the thing we're digging is the most important thing! It won't be so easy for the Deadwood Dao Master to attack us. We need to use this limited time to dig up that thing as soon as possible and properly protect it. ”

Ouyang Jue said calmly.

"Good!"

"Good!"

Xin Ning and Kong Jie quickly nodded in agreement.

They felt that although the black iron skeletons and bloodthirsty bats that attacked them looked terrifying, they were not too threatening, and at most they could destroy the defense line in the mine, and they might not be able to attack the bottom of the pit.

Even if the Deadwood Daoist took action himself, Hu Tu should be able to at least draw with him.

Xin Ning was a martial arts master-level monk, and in the face of this situation, he was much calmer than those ordinary special service guards.
