On the other side, in the ghost plane, Kate and other dragon knights went through great pains to successfully force out the radiation.

After a brief rest, just as they were about to tackle the tough problem, Martin's voice suddenly rang out in their minds: "Kate, how are you guys progressing?"

Kate quickly responded, "Your Majesty, we have now advanced to City A, but have encountered some difficult problems. We are currently trying to resolve them, so please rest assured, Your Majesty."

Martin continued, "Kate, I'm well aware of your abilities. But we must speed up now and not waste too much time on these troublesome matters."

"You must seize the plane core immediately, and I will pick you up later."

Upon hearing this, Kate quickly replied, "I understand. I will carry it out immediately. Your Majesty, please rest assured." Martin then cut off the connection.

He turned to face the other dragon riders and shouted, "Your Majesty's orders, everyone has heard! We must complete the mission His Majesty has assigned us as quickly as possible. Let's go!"

After saying that, he took the lead and flew into the sky with his team to search for the core of the plane.

During the flight, they were attacked by many ghosts.

However, faced with the powerful dragon breath of the dragon knights, these ghosts were instantly extinguished.

Soon, they saw a group of ghost guards with the strength of mid-level gods guarding a huge blood-red crystal.

Seeing this, Kate and others immediately realized that this crystal was the core of the plane they were looking for.

Kate quickly estimated the number of people on both sides: twenty on her side and thirty on the enemy side, but thanks to the powerful strength of the dragon knights, the advantage was still on her side.

At that moment, Kate took the lead without hesitation and rushed towards the ghost guards like an arrow.

Perhaps the plane core felt threatened, so it began to summon ghosts of the strength of middle gods from other places to come for support. Kate and other dragon knights felt the ghosts of the strength of middle gods rushing towards them quickly.

"Quick battle and quick decision! Attack those ghosts with all your strength and don't attract the radioactive ghosts in the pit, otherwise it will be difficult to deal with!" Kate shouted anxiously.

The other dragon knights responded in unison, the divine power in their hands surged more violently, and the dragons under them also cast dragon language magic that consumed a huge amount of energy, launching an attack on the core of the plane.

Seeing this, the ghosts immediately stood in front of the core of the plane.

Seeing this, the other dragon knights ordered their dragons to use dragon language magic to directly attack the core of the plane.

Sure enough, the ghosts tried desperately to stop them, and several ghosts were instantly killed by dragon language magic.

Seeing that this method was very effective, Kate immediately shouted to the other dragon knights, "Attack the plane core with all your strength. Ignore the harassment from the ghosts. End the battle as soon as possible and retreat once you have the plane core!"

After saying this, he injected all his divine power into the giant dragon under him, instantly increasing the power of the dragon language magic several times.

The ghosts were completely unable to resist. With a loud "bang", the dragon language magic directly broke through the protective wall of the plane core, revealing a plane core beating like a heart.

At this moment, ghosts from other areas noticed the commotion and rushed to support.

Kate acted decisively and ordered the dragon knights to stop the ghosts coming to support her, while she herself rode her dragon and rushed towards the core of the plane.

He took out a specially made box, and with his divine power, he steadily took out the plane core and quickly put it into the box.

As soon as the plane core was removed, the space began to slowly collapse.

The mission has been completed. Kate doesn't want to stay here and cause more trouble, so she immediately calls on the other dragon knights to evacuate quickly.

Kate and the dragon knights quickly evacuated to a distant place, and more than twenty ghosts with the strength of middle gods were chasing them relentlessly.

Not long after they left, more than a hundred radiation ghosts appeared at the place where the plane core was originally placed.

The leading ghost looked at the empty space and his expression instantly became extremely ugly.

It knew that if it couldn't take back and restore the core of the plane before it collapsed, they would all be doomed.

So, it hurriedly called other radiation ghosts and quickly chased in the direction where Kate and others evacuated.

Ten minutes later, after traveling at full speed, Kate and the others finally arrived at the place where the plane channel was opened.

After waiting for a few more minutes, Kate and the others felt their scalps tingling and became extremely anxious as they looked at the hundreds of ghosts with the strength of middle-level gods rushing towards them from afar.

At this moment, a dimensional channel began to slowly build.

Soon, the channel construction was completed.

Kate gave an order and immediately flew into the passage with the dragon knights.

Seeing this, the ghosts that were chasing after him also rushed in without hesitation.

As they entered, the plane channel gradually began to close.

The ghosts that failed to enter in time could only howl to the sky as they looked at the closed passage, their voices filled with resentment.

The dragon knights quickly passed through the plane channel and successfully arrived at the light column plane.

The twenty or so ghosts followed closely.

Martin saw it and immediately ordered Betan to take action. Betan's figure flashed and instantly released a powerful force, annihilating more than 20 ghosts in one fell swoop.

Betan handed all the twenty or so divine powers he had obtained to Martin.

At this time, Kate came forward and handed Martin a space ring, which contained the key items obtained in this operation - the plane core and a large number of divine powers.

Martin took them one by one, then turned to Kate and the others and said sincerely: "You have worked hard, so take a good rest during this time."

After saying that, Martin led the dragon knights to open a space crack. The group stepped into it and went straight to the Dragon Cliff of the Royal Dragon City Palace.

[Host: Martin]

【System Level: Level 4】

[Current Level: Middle God]

[Sworn Guards: 5,237,633 people]

[Contracted Dragons: 152, Dragonmen: 31]

Energy Reserve: 5,675,231

[Plane Core: Zero]

Martin carefully checked the system panel, and then charged the plane core into the system.

He planned to wait for Kate and others to rest for two days before arranging for them to continue to the next small plane.

After all, there are a large number of small planes attached to the light column plane, and Martin is eager to speed up the progress and improve the strength of his dragon knights as much as possible.

According to his speculation, in order for a dragon knight to be promoted to the star level, ten lower-level plane cores or one intermediate-level plane core are needed.

At this moment, in the water world, the two teams of dragon knights who entered first encountered difficult situations.

When they stepped into this place, they were shocked to find that the last land in this world had completely disappeared. As far as the eye could see, there was only vast ocean, and there was no trace of land life.

Just as everyone was alert to their surroundings, the calm water suddenly surged.

In an instant, a huge mouth suddenly appeared under the water, like a black abyss, carrying a fierce momentum, biting towards the dragon knights viciously.
