After the legion had assembled, the legion commander simply said, "Let's all go back alive together," and then ordered the legion to leave the camp in an orderly manner and march towards the colorless crystal area.

The ten dragon knights had already flown into the air in advance, and Captain Kate was not sure whether the people of the high tower and the people of the low tower had already formed an alliance.

But according to the memory of the low tower man, the high tower people were like nobles, and the low tower people were like knights, unless the low tower people pledged allegiance to the high tower people... Kate sincerely hoped that this would not happen.

The ten dragon knights deliberately lowered their flying altitude. They did not want to cause trouble and lure out the powerful "toys" of the tower people.

After entering the colorless crystal area, the feeling here is no different from the previous areas, dead silent.

The crowd continued to move forward, and strangely, they did not encounter the expected sneak attack.

Did the enemy give up resistance? But how could that be possible?

A few days later, the army successfully reached the center of the colorless crystal. The army leader immediately ordered the army to start digging downwards. The progress was very smooth, and they soon dug to the underground city.

However, as soon as the ground was dug, colorless energy beams shot out towards the hole.

In an instant, several dragon beast knights were melted, without even having time to let out a scream.

The dragon knights flying at low altitude noticed the energy attack and immediately flew towards the underground city together.

But the dragon knights did not notice that after they left, huge eyes in the colorless crystal area opened one after another and looked towards the central area.

Then, led by the colorless man above them, they all headed towards the central area at an extremely fast speed. The second, third, fourth and fifth legions on the ground noticed the slight vibration of the ground and became alert.

The eight legion commanders and deputy legion commanders also flew out of the camp and looked at the ground at a low altitude.

Suddenly, colorless crystal monsters on the ground stood up one after another. There were more than fifty of them if you counted carefully. The dragon knights also encountered trouble. More than thirty makers cooperated with energy beams to continuously attack them.

Captain Kate sensed the vibration from above and immediately ordered the First Legion to go up for support, leaving this matter to them. The commander of the First Legion had already sensed the vibration from above.

However, seeing that the dragon knights were in danger, he wanted to go up and help.

After receiving the assurance from Captain Kate, the commander of the First Legion immediately led the legion upwards.

When they arrived, the other legions were already engaged in a melee with the behemoths.

Each knight order cooperated with each other and tried to contain the behemoths, while the legion commanders acted as the main force, moving flexibly on the battlefield, waiting for opportunities to destroy the behemoth knights.

Upon seeing this, the First Legion led the army forward without hesitation and joined the battle with the behemoth.

Previously, the legions were reserved for fear of causing too much commotion.

At this moment, under the leadership of the leader of the domain knights, they either dispersed to contain the behemoths, or relied on their numerical advantage to surround and kill the behemoth knights. The battlefield was extremely brutal.

Although the colorless beast was unable to launch energy attacks, its huge size still caused varying degrees of casualties to the legion.

However, Martin's panel numbers showed no change, offering them no support.

At this moment, a deafening roar came from the underground city.

A dragon knight whose heart was dug out, after obtaining the consent of his fellow dragon, resolutely approached the manufacturers and the city location and chose to self-destruct.

Accompanied by a loud cry of "For Your Majesty", a powerful explosion instantly destroyed a dozen manufacturers and the underground city.

Immediately afterwards, the crystal ground began to sink. The legions engaged in fierce fighting felt the impact of the explosion and clearly noticed the ground sinking, but everyone understood what the explosion meant.

So, regardless of the sinking ground, everyone rushed towards the Behemoth Knight with all their might, and the legion commanders also fought bravely.

During the battle, the dragon beast knights fell one after another, and the crystal beast knights gradually shattered.

In this battle, the dragon knights paid a heavy price of one of their own self-destruction, but they successfully blew up the underground city, and more than a hundred energy cannons were silenced.

The remaining dragon knights were filled with grief as their comrades who had fought side by side with them blew themselves up in front of them.

Filled with grief and indignation, the dragon knights instantly opened fire at full force, and the divine power in their bodies attacked the remaining dozen or so makers like a bursting dam.

In just two minutes, all the makers were killed.

Afterwards, under the leadership of Captain Kate, the dragon knights directly massacred the remaining colorless crystal people below.

Seeing that the colorless crystal people were almost all killed, the low tower people sent out their own guard team, a total of twenty makers.

These makers all possess cores that allow them to launch energy attacks.

As soon as the two sides met, they immediately engaged in a fierce battle. The dragon knights generously stuffed potions into their own mouths and the dragon's mouths.

In the absence of external interference, the Dragon Knight's powerful strength was fully demonstrated, almost completely suppressing the makers.

As time passed, the makers fell one by one. Until the last maker was successfully killed, everyone was injured, with injuries of varying severity.

They poured the divine power potion into their mouths while heading towards the basement.

When everyone stepped into the basement, a magnificent underground palace suddenly appeared before their eyes.

The people from the low tower were sitting in the middle of the hall, looking at them expressionlessly, and then they started shouting loudly.

Since Kate and the others had previously encountered the memories of the Low Tower people, they understood the meaning of their words. The general meaning was: "Invaders, why are you invading our homeland? You, these despicable lower-dimensional creatures, will not end well. You alone will never be able to defeat those damned High Tower people."

After saying this, the leading Low Tower man resolutely chose to commit suicide, and the rest of the Low Tower people followed suit.

With the death of the low tower man, a series of "bang bang bang" explosions suddenly came from the palace, and the entire palace began to collapse violently in an instant.

Seeing this, the dragon knights hurriedly ran away.

The collapse of the underground palace was like a chain of disasters, completely destroying the already shaky underground city.

Driven by the collapse of the palace, the underground city also quickly collapsed, and the entire underground space collapsed as well.

On the ground, the knights and the beast knights were fighting fiercely, and they clearly felt the ground begin to collapse violently.

However, no one chose to retreat, whether it was the Behemoth Knight who was determined to kill the invaders, or the Subdragon Knight who was determined to avenge the Dragon Knight and his comrades.

At this moment, the ground collapsed without warning. Because of the suddenness of the incident, a large number of dragon knights and behemoth knights were unable to avoid it and fell into it.
