"That's not right. Even if they have a mana storage device, they shouldn't be able to last this long!"
The five rune puppets had yet to run out of mana after a week of siege. This was extremely abnormal, and a king-class expert voiced his doubts.
"Indeed, that's not right. It's as if the five rune puppets have an endless supply of mana!"
Gray frowned in doubt as well. Even if they had a mana storage device, they shouldn't have run out of mana after being besieged for a week. This was completely different from the rune puppets of the empire that had appeared before.
"Rune masters, what do you think about this?"
Jennifer Austin, a thrice-transformed king-class expert from the Jewel Kingdom, asked the twenty or so rune masters politely.
"That's not right. Even if they have a mana storage device, they shouldn't be able to last this long."
One of the rune masters frowned.
"Can you determine the reason?"
Blair Blaze, a thrice-transformed king-class expert from the Flame Kingdom, asked.
"The rune standards of this graveyard far exceed the rune standards of the four kingdoms. We can't be sure if we can find the reason. Moreover, if we want to find the reason, we have to observe the rune puppets from a close distance. However, with our strength …"
A rune master said awkwardly. The twenty or so rune masters weren't strong, and they couldn't get close to the rune puppets at all.
"We'll have to trouble you, rune masters. Please rest assured about your safety. We'll send king-class experts to protect you."
Difoni Violet, a thrice-transformed king-class expert from the Purple Moon Kingdom, assured them.
Another round of attacks began, but the difference was that the twenty or so rune masters had appeared in the group and were protected by several king-class experts.
With fewer king-class experts besieging the rune puppets, the pressure on the four kingdoms and the fifth force increased significantly. Some king-class experts were injured in the battle, but they retreated without any casualties.
"Rune masters, how is it? Have you determined the reason?"
Jennifer Austin asked.
"We have a rough idea, but we can't be sure."
One of the Rune Masters said after a discussion among the twenty or so Rune Masters.
"What's the reason?"
Difoni Violet asked hurriedly.
"If we're not wrong, there's a very peculiar array pattern on the ground where the runic puppet is located. This array pattern can continuously channel mana into the runic mechanism."
The Rune Master said.
"What?
It can actually continuously replenish mana … "
Hearing this, Gray and the others couldn't help but be shocked, and then they all frowned.
Runic Puppets were able to continuously replenish their mana, which meant that they could continuously fight. In other words, it was impossible to make the Runic Puppets stop fighting by exhausting their mana.
"Masters, I wonder if there's any way to break it?"
Blair Blaze asked.
"In theory, if there is a runic array that can cut off the transmission of magic power, it can naturally cut off the replenishment of the runic puppet's magic power, causing the runic puppet's magic power to be completely exhausted."
Another Rune Master said.
"I wonder if you're confident?"
Jennifer Austin asked hurriedly.
"This is the first time we've encountered a runic array that can transmit mana. We can't guarantee that we can crack it."
A Rune Master had a difficult expression.
"Please try your best to crack it, Rune Masters."
Difoni Violet said.
"We can only say that we'll try our best. We can't guarantee success."
The twenty or so Rune Masters all said.
Clang, clang, clang!
With the cooperation of the Kings, the twenty or so Rune Masters spent several days and finally cut off the runic array that could transmit mana, cutting off the source of the runic puppet's mana.
Then, after a few days, with five consecutive clangs, five runic puppets that were more than ten meters tall had exhausted their mana and completely collapsed.
The thrice-metamorphosed Kings of the Four Kingdoms and the Fifth Force all quickly put away the runic puppets.
"What a good thing!"
Gray looked at the five people with slight envy as they put away the runic puppets.
The runic puppets were powerful to be able to withstand their continuous attacks for so long without any damage. If they could crack the runic puppets' operating runes and control them, they would immediately have the battle prowess of a thrice-metamorphosed King that was almost unkillable.
Unfortunately, with his current strength, it was impossible for him to have any ideas about such things. If he had the strength, he wouldn't mind snatching the runic puppets that the Flame Kingdom was besieging to vent his anger.
Those below King were left at the edge of the square. The Kings, including Gray, walked to the two metal doors.
These were two huge doors made of black metal. They were extremely huge, more than ten meters tall and more than twenty meters wide, as if they were specially made for giants.
On the black door on the left was a giant beast. It was a giant beast that looked like a lizard. Its body was covered in scales and there were three sharp horns on its head. The surface of its body was full of complicated natural patterns, giving it a mysterious feeling.
"King Blood Beast, Poison King Dragon. No, it should be Magic Light Blood Beast, Magic Poison Dragon!"
Gray carefully identified these patterns and recognized the giant beast.
Magic Poison Dragon, a Magic Light Blood Beast of the Poison Lizard Sequence. It was good at using poison, and its poison was extremely corrosive. It was a Blood Beast with dragon blood.
Gray couldn't help but think of the Poison Lizard Sequence Blood Technique that he, Sophia, and Francis had obtained some time ago. He guessed that the owner of the tomb might have cultivated the Poison Lizard Sequence Blood Technique.
The metal door on the right wasn't carved with a Blood Beast. Instead, it was a very special symbol. At the top was a huge crown, and under the crown were crossed swords.
"This is the symbol of the imperial family. The owner of the tomb must be an important member of the imperial family."
Seeing this symbol, a King expert judged.
"The tomb of an important member of the imperial family!"
Judging this identity, many King experts couldn't help but have a burning look in their eyes. The imperial family of the empire was a force more powerful than the current four kingdoms. The wealth they possessed was unimaginable.
Unfortunately, until now, no imperial family tomb had been found. Now, one had finally been found, and they were about to enter the final chamber of this tomb.
Some King experts couldn't wait to reach out their hands, trying to push open the metal door.
Although the two metal doors were huge and weighed dozens of tons, they weren't ordinary people. They wouldn't be stopped by this weight.
Crackle!
Just at this moment, a sudden change occurred. A large amount of black lightning suddenly appeared above the metal door.
The three King experts who touched the metal doors were instantly entangled by this black lightning. Then, their bodies couldn't help but fall to the ground, charred black.
After falling to the ground, there was no sound at all. It wasn't clear whether they had fainted or died.
"Not good!"
"Retreat!"
The sudden change caused a commotion. Other than the three King experts who had fallen to the ground, it was unknown whether they were dead or alive. The rest of the King experts were so shocked that they retreated, distancing themselves from the metal doors as if they were snakes or scorpions.
After a moment, after confirming that there was no attack, all the King experts stopped. They looked at the bodies of the three King experts who had fallen in front of the door with lingering fear.
"There's a rune mechanism, and it's so powerful!"
Gray's forehead had a trace of cold sweat. After spending a full two weeks, they had finally gotten rid of the rune puppet. All the King experts couldn't help but let down their guard. Even he was somewhat relaxed.
He didn't expect that there would be a rune mechanism at the door of the final chamber, and that it would be so powerful.
Whoosh! Whoosh! Whoosh!
Three figures quickly rushed to the three bodies on the ground. They each grabbed one person and quickly retreated. These three people were Blair Blaze, Jennifer Austin, and Difoni Violet. The three people who had fallen were from the Blaze, Gem, and Purple Moon Kingdoms.
"Dead!"
The King experts of the three kingdoms quickly went forward to check on the situation of the people who had been attacked. Gray also went forward to check on the King experts of the Purple Moon Kingdom. The answer he received shocked him.
The King expert of the Purple Moon Kingdom was dead. He had been killed by the rune mechanism just now. It wasn't just him. The King experts of the Flame Kingdom and the Jewel Kingdom were the same. They had all died to the rune mechanism just now.
After investigating this chamber, many King experts below King level had died. Now, the dead King experts had finally appeared. There were three of them.
"Damn it! There's a rune mechanism, and it's so powerful!"
The King expert of the Scarlet Kingdom was relieved. The King experts of the Purple Moon Kingdom, Gem, and Blaze Kingdom were all gloomy.
"What do we do now?
Can we get a rune master to crack it? "
A King expert stared at the metal doors with a worried frown.
"It can't be cracked. The runes are on the metal doors. There's no way to inlay them."
A King expert who was a rune master shook his head.
"We can only force our way in. Let's attack together. We have so many King experts here. I don't believe we can't even break two doors."
A King expert said.
"Let's attack together!"
All the King experts of the four kingdoms and the fifth power joined forces again. This time, it wasn't rune puppets, but two giant metal doors.
Boom! Boom! Boom!
A continuous barrage of attacks bombarded the metal gate. Every time the gate was attacked, black lightning would appear on the surface of the gate. However, in the face of so many attacks, even the black lightning could not withstand them all and was annihilated by the barrage of attacks.
Boom!
A few days passed. After more than ten rounds of attacks, the metal doors were full of dents. Finally, with a loud boom, the two giant metal doors exploded. The chamber behind the metal doors was exposed.
Whoosh! Whoosh! Whoosh!
At this moment, all the King experts, including Gray, couldn't help but increase their speed to the maximum. They rushed out of the chamber.
