Witan started absorbing mana while forming new undeads. Humanoid undead and undead skay quetzals rose within 100 meters. After they rose, they started attacking everything.

The humans saw what was happening and couldn't do anything, they were too busy fighting the skay quetzals. Time kept passing on with no one to stop Witan. Waves upon waves of undead formed. A group of undead connected and started forming a humanoid undead giant fifty meters tall.

The undead giant walked around and smashed its fist into ships. Seeing this, many people on the warship lost hope. Some warships that managed to escape the harbor didn't turn back and kept sailing away.

After sailing a safe distance away, they stopped. No one was going to give up a low rank 4 mana core and more warships were sailing in from other kingdoms. They all stopped at a safe distance and didn't attack. They were all waiting for an opportunity. For now, everyone had a truce agreement.

Witan saw from afar what they were doing but didn't mind. Currently, Witan was trying to make his undead giant bigger. More undead latched onto the undead giant. They carried ship mast and ship hull with them. The ship hull made the armor and the ship mast made spike rose from the undead giant.

After a long while, the harbor was mostly filled with undeads. The undead giant now a hundred meters tall looked at the blue force field covering Bikal. It walked forward with Witan on its shoulder.

Bringing its fist back and getting into a boxing stance, it punched forward. The fist collided with the force field creating a loud boom and a shock wave. The force field didn't breakthrough, it held strong.

Seeing this, Witan wasn't frustrated, he knew that this force field was powered by the island mana vein. The undead giant brought its fist back again and punched. Punches after punches it threw.

Up in the sky, Tesra spoke.

"We should save them, Jill."

"Why?"

Tesra looked at Jill surprised. Jill saw what she was thinking and sighed. She looked up at the stars and spoke.

"Do you know what my goal currently is Tesla?"

Tesra shook her head.

"My goal currently is to reach rank 6. I've read the history book and there doesn't seem to be a single rank 6 in this world."

Tesra hesitated for a moment and spoke.

"Why do you wish to reach rank 6, aren't you already strong enough."

Jill smiled at her. "I am indeed already strong enough, so strong that I could probably destroy this world with a single spell."

Tesra became shocked, destroying the world with a single spell was simply unimaginable to her. Jill saw that she was scared and calmed her.

"Don't worry, I don't want to destroy the world. What I want is to see the unknown. I want to see and know what's there at rank 6. Other than that I'm pretty much neutral."

Tesra nodded and became calm. She never felt very connected to the world until Jill told her she could destroy the world. Thinking of what life would be like without a world, Tesra couldn't imagine it.

"What does not saving them have to do with reaching rank 6 though Jill?"

"Good question, but that's a secret. Don't worry about them dying though, they have a secret weapon."

Tesra became surprised at the word secret weapon. She looked at Jill expectantly.

"It wouldn't be a secret if I told you, just keep watching and they might use it."

Below, the undead giant kept attacking the force field. Inside the force field, everyone was looting and running. Commander Laiga looked at the force field and spoke to one of the mages.

"How long will the force field last?"

"Not long enough before we can charge up the cannon."

"Do we have Skay Claw and the low rank 4 mana core?"

"Yes sir."

"Keep charging the cannon, I'll try to buy time."

With that, Laiga dashed towards the force field. After he reached the force field, he spoke loudly with mana.

"What are your demands."

Witan looked down at him suspiciously.

"Give me the low rank 4 mana core with Skay Claw and I'll leave."

"We can give up the low rank 4 mana core, but not Skay Claw."

"Don't test me, knight, I see you're trying to buy time."

The undead giant reinforced its right fist with fire and wind. It then punched forward. Seeing that the fist would destroy the force field, Laiga decided to block it.

Laiga flew up and slashed forth an ice attack with all his mana. The ice slash flew and collided with the undead giant fist. The fist became brittle with ice and it crashed down on the force field. Upon impact, the fist broke to pieces.

Pulling its arm back, the undead giant arm regrew. In the distance in the island, a giant cannon was brought forth. A transmission came to Laiga.

"It's charged, sir."

Laiga flew out of the firing range.

"Fire away."

A loud boom roared throughout the island. A giant ball of fire flew through the sky. It was extremely fast and the undead giant couldn't dodge in time. The force field had already opened up and the giant ball of fire flew through.

The giant ball of fire impacted the undead giant and an explosion occurred. The light brightened the whole island. After the explosion settled, everyone became calm.

Laiga flew towards where the undead giant once was. There was only a burning surrounding outside the force field. Laiga spread his mana perception to detect if Witan was still alive. After a while he stopped, he couldn't sense Witan's life force at all.

Laiga then flew back to establish order. While Laiga was flying back, an old hand rose from the water. Climbing up on some debris, Witan looked around. After seeing no one, he floated to shore.

He passed through the deactivated force field and onto dry land. Right now Witan was very weak, he had used all his mana to protect himself. With the little mana he regenerated, he used it to hide from Laiga mana perception.

He sat on the shore silently trying to regenerate his mana in order to create new undeads. In the night, he heard a roar. Looking from the island into the sea, he saw a dragon as black as the night breathed gaseous poison onto the warships in the distance. The dragon was dark as coal with a light green stripe over it's body. It was 30 meters long with four legs and four wings.

Fireballs and ice spikes flew with none managing to land on the dragon. While flying, the dragon spoke loudly.

"Give me the low rank 4 mana core humans."

It then took a deep breath and breathed a stream of gaseous poison. Soon the sea turned to poison and the warships started backing off. A commander looked at the dragon coldly.

"Being out the Sky Slayer."

"Yes sir."

The lieutenant went and got the soldiers to bring out the sky slayer. The sky slayer was a very famous ballista. It was a ballista made with the skay quetzal lord wind tendon. The sky slayer looked like a flying skay quetzal.

The bolts for the sky slayer were none other than the skay quetzal lord beak. Its piercing powering was enough to pierce through a high rank 3 mana force field. Because the skay quetzal lord only had an upper beak with a lower beak; there were only two ballista bolts for the sky slayer called skay lord bolts.

Loading the sky slayer with a skay lord bolt was extremely hard, it required two people of low rank 2. The warship belonged to the Wimgale empire, the one who profited the most after the skay quetzal lord's death. They had plenty of low rank 2 in the empire.

The skay lord bolt was loaded. The two low-rank 2 aimed it at the dragon. As the dragon got close to their ship, the commander spoke.

"Cast the spell."

A group of mages on the warship casted a spell together. From each of them, a chain of light flew out of their heart. There were about 30 chains in total. The chains flew towards the dragon and bounded it.

After it was bounded, the sky slayer fired. The bolt flew at sharp speed and pierced into the dragon's neck. It struggled in pain and broke the chain. It tried to burn the bolt but that didn't work. It fell into the water and its green blood spreaded around the waters.

Using its mana, it held onto its lifeline and flew away. Whiling it was flying another sky lord bolt came flying. The commander didn't want to lose a sky lord bolt and gain nothing. The sky lord bolt flew into the dragon's back and it writhed in pain. It couldn't scream with its neck impaled. Looking at the helpless dragon who fell into the water again, the commander spoke.

"Kill and harvest it."

The lieutenant nodded and gave the command, soon every ship of the Wimgale empire sailed towards the struggling dragon. The dragon looked at them in fear. The warships loaded the cannons and fired them upon the dragon. Cannonballs after cannonballs flew into the dragon. The dragon felt every cannonball like it was a punch. After quite a while, the dragon died.
