At this moment, the Dark Elf King, who was unconscious due to the strong impact, was being carried by a black feather and continued to sink underground.

Soon, they arrived at a mysterious underground space.

As it sank, the energy of the black feather was about to be exhausted. It used up its last bit of strength to wake up the unconscious Dark Elf King, and then turned into ashes and dissipated.

The Dark Elf King slowly woke up and looked at the unfamiliar scene in front of him, his heart filled with shock.

He really didn't expect that Martin White had such a powerful dragon knight.

According to what Your Majesty said, weren't Martin White's main forces transferred to the capital of the Northern Continent?

How come four mid-level dragon knights suddenly appeared?

The Dark Elf King thought as he slowly stood up and looked around.

The murals around the room depicted a fierce battle between the demons and angels in hell. In the end, both of them fell into the reincarnation pool and then fell into hell.

In the center of the mural, there is an extra-large altar in the shape of a pyramid.

The Dark Elf King walked straight towards the altar. He tried to fly closer to the altar, but as soon as he left the ground, a terrifying gravity suddenly pressed down on him, knocking him heavily to the ground.

The Dark Elf King couldn't help but spit out a mouthful of blood. Now he didn't dare to try to fly again. He could only move towards the altar step by step with difficulty.

At this moment, the battle at the plane channel in the capital of the Northern Continent was fierce.

Hill retired from the battlefield early due to lack of Martin's energy treatment.

The four planetary dragon knights were like four solid nails, blocking the demon.

However, as more and more demons awaken and rush over, the situation becomes increasingly serious.

However, due to the limited space within the plane channel, these demons can only worry outside and are unable to enter.

At this time, a demon son looked confused and couldn't help asking, "Why do you have to attack this plane? Aren't there many other intermediate planes?"

As soon as the words came out of his mouth, a huge demonic palm slammed down and directly knocked the son of the devil into the ground.

"You idiot!" shouted a demon who was obviously of higher status.

"Other planes either already have owners or are under protection. How can this plane be the same? If you don't die here in battle today, I'll show you how I'll deal with you when I get back!"

The other sons of the devil saw this and looked at their companions who were slammed into the ground with a look of schadenfreude.

The son of the devil finally struggled to crawl out of the soil, his face looking extremely ugly.

He never expected that a careless remark of his would bring about a fatal disaster.

But the situation was critical at the moment, and he had no time to care about anything else. He could only suppress his anger and fear and prepare to fight again.

After a few days, the corpses in the plane channel piled up like a mountain, almost blocking the channel completely.

In desperation, the demons had to suspend their attack and start cleaning up the corpses first.

At this moment, Betan and the other four people as well as the dragons they rode were all exhausted and panting.

If it weren't for the energy support provided by His Majesty, they would have been unable to withstand the demons' attack.

The Guild Master was also under immense pressure. Setting up a seal was no easy task, let alone a reverse seal, which was extremely difficult.

The president was so tired that sweat was pouring down his forehead, but he still gritted his teeth and persevered.

Fortunately, after a long period of hard work, the sealing work is nearing completion and success is in sight.

The demons paused their attack to clean up the corpses, but Betan and his three companions knew that once the passage was cleared, the pressure on their side would increase dramatically.

So, they quickly gathered their divine power and transferred it to the giant dragon under them, driving the dragon to breathe dragon breath.

However, as soon as the dragon breaths were spurted out, they were easily blocked by several planetary demons.

The demons were clearing the corpses even faster. Betan and the other three were extremely anxious, but they had no idea what to do. They could only keep drinking divine potions and use the energy bestowed by His Majesty to recover as quickly as possible.

Half an hour later, the demon corpses in the plane channel were basically cleared.

Betan and his four companions mounted on the dragon's back again, and the four giant dragons roared in unison, which frightened the sons of demons who were about to attack and made them stand still, not daring to move.

Seeing this, the demon god above cursed "waste" in annoyance, and then rushed straight towards Betan and others.

The other seven or eight demons followed closely behind, and the two sides engaged in a fierce battle again.

Since it takes time for the demons to revive, and the space in the plane channel is limited, it is difficult to maneuver with too many people. The demons can only adopt a strategy of round-robin battles, hoping to exhaust the physical strength of Betan and the other four, and then kill them in one fell swoop.

Just when the two sides were fighting hard, the plane channel suddenly trembled violently.

Everyone present stopped what they were doing instantly and turned their gaze in the direction of President Pro.

He put the origin of the light column plane into it, and pure white light spread out in all directions like ripples, and the plane channel became increasingly unstable.

The demons became extremely anxious upon seeing this. The demons outside the passage no longer cared about anything else and squeezed in. Many demons were crushed to death.

They launched a fierce attack on the four planetary dragon knights like crazy, and at the same time continued to rush towards the position of President Pro.

How could Betan and the other three not understand the intentions of the demons? Even if they were seriously injured, they would force all the demons to retreat.

At this time, Hill came to the plane channel in full condition. Seeing the four dragon knights bleeding, she was anxious and wanted to join the battle immediately.

However, Betan reached out to stop her and said anxiously: "Hill, go and protect President Pro's safety!"

Hill hesitated for a moment, but soon realized that the situation was critical, and finally came to President Pro.

The demons continued to arrive in an endless stream, and gradually, the demons gained the upper hand and suppressed them.

The dragon knight Loga was careless and was accidentally hit by the energy attack of the demon god. He and the dragon under him fell heavily to the ground like a cannonball.

Loga fainted on the spot, and the dragon struggled to stand up, but was powerless. In the end, he could only collapse to the ground powerlessly, spitting out dragon blood from his mouth.

Seeing this, President Pro knew that the situation was critical, so he accelerated the sealing process.

I saw pure white original energy slowly gathering towards the center.

The demons were keenly aware that the entrance to the dimensional channel behind them was gradually shrinking.

Their faces were filled with resentment, and they looked at the dragon knights with resentment.

Some demons realized that the situation was hopeless and chose to leave immediately.

However, there are still some demons who are unwilling to give up and try to go to the light column plane, so they are still fighting desperately with the dragon knights.

The unconscious Roga and his injured dragon were recovering bit by bit thanks to the energy Martin delivered in time.
