Numerous gates and defenses have been installed at this end of the tunnel, making it impossible for the demons in the north who only have cold weapons to leap forward.

A car drove up, and Gao Peng saw some demon corpses piled up in the car body.

As he continued to advance, he reached the end of the defensive position after a few kilometers, but further on it was still flat, the rocks had already been shattered, and the smoke had not completely cleared.

With the defenders in awe, he continued alone, trying to see what was going on on the enemy's side.

Walking out of the smoky area, murals and reliefs began to appear on the rock wall, which was originally an important passage between the demon world and the north and south, but unfortunately now that the war is going on, it is impossible to pass freely.

Of course, this passage is only the only way north into the Wailing Plains, and there are other roads to other areas.

The existing intelligence shows that the underground world is too big, and the bottom of the ocean is a forbidden area for humans, but further down there is a vast underground space, which is just a series of large and small areas, distributed with various demon races and inanimate forbidden areas.

The tunnel was far longer than Gao Peng imagined, and he knew that it would be better to get a horse, and he didn't see any demons along the way, only some bloodstains after the retreat of the wounded soldiers.

Even the entrance to the cave on the opposite side was not guarded by demons, and when I came out, I saw many demons hovering in the air riding giant birds, and there was a majestic underground city in the distance.

Gao Peng saw that this was a demon who couldn't attack it, so he simply gave up.

There are constant demon harassment, and they are just curious or arrogant stragglers, who pay with their lives for their stupidity.

Seeing Gao Peng walk out of the cave, a huge strange bird swooped down, its huge claws grabbed at him, and the thin cavalry on it screamed excitedly.

The next moment, the giant bird's head was pierced by the Zhutianmu sword, and its huge body fell, and the cavalry was also shot off at the time of the strange scream.

Gao Peng came to the corpse of the fallen cavalryman, tore off his cloak and draped it over his body, put on his hood and continued to move forward, but there was a coquettish cry from behind.

"Daddy wait for me......"

Gao Peng turned his head to see that it was Gao Weining chasing after him, standing in place with a smile on the corner of his mouth.

"Does your sister know that you threw it?"

"You know, she said that for the sake of Liwei, let me burn the city in front of me."

"Waste!"

"Anyway, it's all built of stone, and the city can't be broken."

Gao Peng took her little hand and walked forward, several sky knights flew over, Gao Weining just waved his hand casually, and dense fireballs flew into the sky.

The Sky Knights dodged quickly, but the fireballs were able to track, and when they hit their targets, they exploded and smashed them to pieces.

"Woo woo woo ......"

The desolate horn sounded, and a group of cavalry rushed violently, Gao Weining just stomped his feet, and a sea of fire enveloped the cavalry, and a terrible scream came, and no cavalry could rush out of the sea of fire.

When passing by a boiling magma pool, Gao Weining put his finger to his mouth and whistled, and the magma began to boil, forming a human figure and crawling out, continuously charging towards the city ahead.

"Close the gates!"

"Run...... Run away......"

The huge dungeon was in chaos, and when the heavy city gates closed, an even more terrifying scene appeared, and those humanoid magma gathered together to form a terrifying creature with a height of 100 meters.

Ignoring all attacks, the terrifying creature strode over the walls toward the center of the city, where a fire burst into flames.

As soon as they reached the center of the city, the huge body immediately collapsed, and it turned into countless magma people scattered and attacked, and soon the entire city was in flames.

Burning the city!

This was just Gao Weining doing it alone, and Gao Peng was also shocked.

But this girl dozed off boredly, was held in Gao Peng's arms, snapped her fingers before falling asleep, and the magma flowed out of the city again and re-converged into the magma pool.

I've got a monster!

Thinking of the other children, Gao Peng smiled bitterly, hugged Gao Weining and sat on a stone, looking at the city that continued to burn.

There was a tremor on the ground, and a huge mechanized force drove through the tunnel, followed by an endless field of ground troops.

The soldiers looked at the burning city in shock, and then looked at Gao Peng and Gao Weining, all of them were full of awe.

These are the vanguard troops, waiting for the flames to go out and the city to cool down before going in, the luxury car pulled by eight monsters drove to the front and stopped, and Gao Peng got into the car with Gao Weining, who was asleep.

Gao Yanan lay on her side in the car, smiling and nibbling on fruit, as soon as Gao Peng put Gao Weining down, she snuggled up.

A month later, Gao Peng added another son, and Gao Yanan's troops also began an epic northward journey, and Gao Weining, who participated in the war with the troops, already had a resounding name.

Queen of Flames!

This is the title given to her by Gao Peng personally, the first prince under the two emperors of the Gao family, as the other children grow up, it is not so easy to get the prince.

Gao Peng, the terrifying Demon Emperor in the underground world, returned to the surface world with two babies in his arms, and lived a harmonious and peaceful life with his wife and children.

Ten years later, the underworld was unified by Gao Yanan and became a veritable regent.

The pattern of the terrestrial world also changed, and a unified federation was formed, and the two sides signed a non-aggression pact.

The underground world is all open to humans, becoming a paradise for adventurers, and some demons that conform to human aesthetics are also allowed to appear in the surface world.

And Gao Peng has become a legend of the people, when passing by the heavily guarded old Gao family manor, they will all cast awe-inspiring eyes!
