200 to 300 meters underground.

The Three-Eyed Worm spewed out a viscous secretion that seeped into the hard frozen soil, releasing a sharp burst of heat, after which the diamond-shaped tooth of the Driller Worm spun rapidly under the pull of its powerful oral muscles, twisting the sudden rise in temperature into pieces.

Behind them were terrifying-looking hellish demons armed with a variety of weapons, most of them with sharp horns and fangs, ranging from the third to the fifth order.

Eighty-six underground tunnels stretch out, leading to the ancient land of the East.

Suddenly, a Drill Worm shattered the frozen ground in front of it and stopped.

But the army behind them did not stop, and together they squeezed it out, and reached an empty underground cavern, which had no roof, and above it was the cold Siberian night sky, with smooth walls, and even spikes placed on it.

More and more demons poured out of the underground tunnels and stopped.

Eighty-six underground tunnels, all of which were blocked by this large rectangular pit.

A Ground Drill worm crawled forward and tried to continue digging at the other end of the crater, but it squirmed two steps before triggering a high-explosive mine.

Rumble!

A radius of more than ten meters of fire swept out, accompanied by countless fragments.

Poof!

The Driller was blown in two, black entrails and thick green blood flowing from the fracture.

It hissed in pain and shrill noise.

And this hiss was more like a signal, and when the demons were slightly commotionious, twenty figures suddenly appeared above the pit.

"Kill!" Jiang Fan shouted with murderous intent in his eyes.

Everyone had formed the Vermilion Bird Demon Burning Array, and this formation had the strongest group damage among the Four Elephant Formations.

Wu Huo'er was in the position of the array, her red hair raised in the wind, the Vermilion Bird mark on her eyebrows shining like flowing lava, and the immaturity of the little girl was not seen in her eyes, but instead of coldness and flame.

"Vermilion Bird Burning Demon, Cleanse the Sky!"

The slender Vermilion Bird Ancient Sword in Wu Huo'er's hand was suddenly raised and placed vertically on his chest.

Within the big array, the Lingqi of the nineteen king-level powerhouses gathered on Wu Huo'er's body like a rushing flood, Wu Huo'er's delicate body trembled slightly, and the Vermilion Bird Sword in his hand swung violently at the demons in the big pit.

Rumble!

The sky seemed to have cracked, and countless fire meteorites appeared out of thin air and fell with a bang.

Thundered!

The earth-digging demons in front of them were hit by a fire meteorite, turning into bloody mud on the spot, and then cut through the scorching stones in all directions, and then incinerated into nothingness by hundreds of degrees of heat.

The flames flooded the crater, and countless buried high-explosive mines detonated at the same time, sharing the feast of fire.

The burning continued for several minutes, and by the time the scorching light of the flames dimmed, the pit was already charred black.

The surrounding melted snow cascades into it like a waterfall, creating a shallow lake.

"Well done!" Jiang Fan shouted, "Change formation, White Tiger Roaring Heavenly Array!" ”

Brush!

The king-level powerhouses quickly adjusted their bodies and turned into a white tiger roaring array.

However, since Bai Yan has not yet reached the king level, he cannot preside over this formation, and Jiang Fan is now presiding.

"Prepare to deal with high-level demons!"

Sure enough, one by one, the sixth-order demons came out of the pit, and their eyes were blood-red and attacked the big array.

"There are a total of eighteen sixth-order, two seventh-order!" Jiang Fan's eyes were slightly cold, "You can't fight!" ”

"The Ground Drill Classes among the Demons should have all died in the Vermilion Bird Demon Burning Array!" Zhang Kaitian observed the big pit for a long time and shouted.

"That's good, retreat while fighting, go!" Jiang Fan ordered.

Everyone immediately retreated, and the two seventh-order demons saw this and led the sixth-order demons to pursue frantically.

"White Tiger roaring in the sky, slash!" Jiang Fan swung his sword to block.

Although this White Tiger Roaring Heavenly Array was only composed of twenty people, all of them were sixth-order king-level powerhouses, so the power of the Great Array was already comparable to the all-out attack of seventh-order powerhouses.

Rumble!

The grand sword light swung out from the Xuanyuan Sword, and instantly passed the body of a king-level demon.

The king-level demon stiffened in the air for a moment before splitting in half along the sword light!

One sword, one sixth-order king-level demon!

However, instead of making the demons cringe, such a horrific killing only aroused the madness in their eyes.

The two seventh-order demons in the lead roared angrily, and their speed increased sharply, quickly approaching the big array.

"A skeleton demon, a frost demon." Jiang Fan's eyes flashed and he continued to retreat with the big array.

On the ground, Bai Cheng lurked more than 5,000 meters in front of the big pit with more than 1,000 soldiers.

"Is this the battle of the sixth-order kings......" Li Tao looked up at the sky, his pupils constantly flashing brilliant explosive fires, "It would be nice if I could reach the sixth-order king-level one day." ”

Bai Cheng stared at the screen, watching the changes in the geological layer.

Until now, the demons have been trapped in the pit, but they have not managed to climb out, which means that they may be able to continue digging tunnels.

Suddenly, Bai Cheng saw that the geological layer had changed, and then the screen showed that the other end of the pit had begun to be "eaten", and new tunnels had been created.

Bai Yan's pupils shrank, and he immediately said: "Comrades, discover a new pothole, prepare to block it!" ”

"Let's go!" The company platoon commanders ordered.

The fighters picked up the sapper shovels and continued digging.

Soon, before the demon horde reached a distance of 5,000 meters, the White Tiger Army had already dug a new big hole.

"Commander-in-Chief Jiang Fan, the enemy still has the remnants of the earth-digging demons, we have dug new holes, please instruct!"

"Three minutes!" Jiang Fan responded when he heard this.

He was now at war with the demons with the other nineteen king-level powerhouses, and he couldn't pull away for a while.

"Three minutes!" Bai Cheng looked down at the screen.

Perhaps due to previous lessons or the number of digging demons, the digging demons were slow to dig this time, and it would take seven minutes to arrive.

"Bury all the remaining mines!" Bai Qian shouted, "Then prepare to evacuate!" ”

"Yes!" The fighters shouted and began to plant high-explosive mines.

Li Tao buried a mine in the soil and marked it, and just as he was about to get up, he found that the snowflakes falling on his feet had turned black.

He looked up in amazement to see a demon with skull wings and horns on top of his head standing in the air, a pair of emotionless eyes looking at them indifferently.

And the black snowflakes that had already fallen all over this new crater had fallen on each of the warriors.

"Company commander!" Li Tao shouted.

The next moment, the black snowflakes writhed like living creatures.

Click.

The snowflakes turned into black poisonous insects, and when they bit down, the black armor was corroded in an instant!

The pit was flooded by a wave of black poisonous insects.

The white tiger mark appeared on the white eyebrows, and his divine power exploded, and he went to save the warrior beside him: "Quickly withdraw out!" ”

The eighth-order demigod-level demon, the king of the plague, Barton, clapped his hands, no longer looking at the underground, but looking at Jiang Fan and the others.

"We haven't found you yet, so you came out on your own?"
