Yu-Gi-Oh!: This is the real duel!

Kyoko and the other two were somewhat surprised to see Peacock Dance suddenly appear.

"Hey? Wu? How did you find this place?"

"Ah! Wu, you've come at the right time. Since you've already summoned your flying mount, we can save one chance."

"Mai-neechan, my brother actually subconsciously mistook that person for you, which is why he showed concern..." Shizuka gently tugged at Mai's sleeve, explaining on behalf of her brother.

"Hmph!" Kong Quewu did not respond, but simply watched the battle silently.

Soon, after being directly attacked, the NPC Peacock Dance also launched a strong counterattack.

Castle was able to counter each move and neutralize the opponent's attacks as much as possible.

After a few rounds, Jonouchi summoned the deck leader, the Flame Swordsman, and a crimson dragon-shaped sword aura swept out, defeating the NPC Mai Kongjaku, who then dissipated and transformed into a pale blue sky gem.

"We won!" Jonouchi exclaimed excitedly. "Huh? What's this gem? It can even drop equipment?"

Peacock Dance, riding her eagle, leaped forward and caught the Sky Gem that was about to fall into the canyon. At the same time, a system notification popped up in front of her.

[Hint: The Sky Gem—proof of the Sky Boss from the Dinosaur Era, and one of the three keys to unlock the Underworld.]

"Huh? Mai? When did you arrive?" Jonouchi was taken aback.

Kong Quewu ignored him and simply analyzed, "The key to unlocking the underground world? It seems that as long as we find two more, we can clear the Dinosaur Era."

"Yoshi!" Honda said, "I bet the game developers and the others have gotten the other keys by now, right? If we just use the Eye of Truth and the warp teleporter to rendezvous with them, won't we get through this quickly?"

Peacock Dance shook her head and said, "It's not that simple. According to the rules, cards used in one era cannot be used in other eras."

"In other words, starting from this era, the method of using those two cards to gather everyone is no longer feasible."

"Huh? What should we do now?" Shizuka asked softly.

Just then, the Sky Gem in Kong Que Wu's hand suddenly burst into a crystal-clear blue light, and the cries of pterosaurs and giant birds came from all directions. When the group looked up, they saw that the sky above was filled with dark, flying beasts!

But they were not hostile at all; they simply kept rotating around the gem.

Peacock Dance was stunned for a moment: "Proof of the Sky Leader... does that mean that as long as I get this gem, I can command all flying dinosaurs?"

Peacock Dance raised the gem in her hand and shouted, "Go find Game and Chess!"

A series of howls followed, as if in response.

Upon receiving the order, the pterosaurs and giant birds scattered and flew off to search for the whereabouts of the others.

"That's great!" Kyoko exclaimed excitedly. "We should be able to join them soon!"

Peacock Dance smiled: "Besides, everyone doesn't need to worry about mounts anymore; each person can even ride one!"

As she spoke, Kong Quewu waved her wrist, summoning several flying dragons that stopped in front of them, and then rode the eagle she had summoned earlier into the air.

Jōnei crossed his arms and snorted, "Tch! I was the one who defeated the NPC, yet she's acting all high and mighty with the reward~"

Shizuka chuckled and pushed her brother toward the pterodactyl mount beside her, saying, "Oh dear~ Mai-san is doing this because she's so close to her brother~"

"Very close? What are you talking about..." Jonouchi blushed again. "Shizuka, why are you talking so strangely these past few days?"

"It's nothing!" Shizuka jumped up, mounted her pterosaur, and laughed, "Brother, if you don't get on now, Miss Mai will be far away~"

The group found their mounts and, led by Peacock Dance, began to search for the others.

Meanwhile, on the other side, after defeating the land boss NPC, Ryuzaki the dinosaur, Yuzuru activated the power of the land dinosaur and quickly reunited with Yugi Muto and Ryuji Otogi.

Within two hours of the arrival of the dinosaur era, the group had successfully collected two of the three gems.

As for the last one, it is in the ocean closest to the Seahorse Brothers.

"Whoosh—whoosh—"

The waves crashed against the rocks, making a series of sounds.

Seto Kaiba and Keihei Kaiba stood on the shore, cautiously gazing at the towering waves rising in the distance!

Amidst the surging waves, a colossal mosasaur, over twenty meters long, roared and charged forward. Above it, a muscular young man wielding a harpoon stared at the two with chilling, hostile eyes.

Seto Kaiba had never participated in the entire Duel Kingdom tournament, but he still had some impression of that duelist in the distance who was not a small name.

In the age of dinosaurs, the prototype of the Lord of the Sea is none other than Ryota Kajiki, the third-place winner of the National Duelist Tournament!

"Ha! Finally, something interesting has arrived. The mere Five Giants are simply not enough!" Seto Kaiba sneered, unfolding his Duel Disk. "However, AI simulated through data can never compare to real duelists!"

"It seems this entertainment program is already coming to an end after just beginning!!"

"duel!!"

"The leader of my deck is—Blue-Eyes White Dragon!!"

Even Yugi wouldn't always choose Dark Magician as the leader of his deck, but Seto Kaiba, this white dragon addict, has never had any other choice besides Blue-Eyes White Dragon since the Duel Kingdom Tournament.

"roar--------------"

A deafening roar rose from the sea as a massive mosasaur leaped out of the water, transforming the surging waves into a battleground!

Streaks of light shone from the Mosasaurus's back, which was as large as an island, and intertwined to form the squares used in the duel!

As the rule field unfolded, Seto Kaiba shouted, "I've already secured the first strike! Draw a card!"

"Attack Position Summon - Dragon Ruler! Then activate the Spell Card - Dragon Summoning Flute!!!"

Seto Kaiba's opening was almost identical to that demonstration battle. In the very first round, the 12-star fusion monster, Blue-Eyes Ultimate Dragon, made a triumphant appearance!

NPC Ryota Kajiki is not weak, but in the end he still couldn't withstand three rounds of Seto Kaiba's strong attack.

In the end, he was defeated and fell into the sea, and the mosasaur transformed into a dark blue leader gem.

After reading the message, Seto Kaiba smugly chuckled, "Heh, it seems these three gems are the key to the next era~"

"I reckon those guys from Youche and Youxi won't get the other two anytime soon."

"Let's go, Guiping. In the end, we still have to take the initiative to find those guys!"

Just then, a spatial rift tore open in front of the two, and a pink disruptor emerged from it, saying arrogantly, "Since you're so bored, why don't you use this time to learn more about things?"

Seto Kaiba scoffed coldly, "Disrupt? Noa is just as repulsive as Yuzuriha, both of them like to use such ugly things... Ha! You pink wretch with a head full of fleshy growths, why should we listen to your orders?"

Disruptive Pink calmly said, "Don't you want to know what kind of being Noa-sama is, and why he insists on fighting you, Seto Kaiba?"

Upon hearing this, Seto Kaiba's gaze turned cold.

His knowledge of Kaiba Noa was limited to the fact that he was Kaiba Gosaburo's biological son. As for what kind of past this guy had, or whether he appeared to avenge Kaiba Gosaburo, he had no idea.

For Seto Kaiba, understanding is a necessary step before defeating his opponent!

If he is completely unaware of the situation in Kaimanaia, then he, who was forcibly brought here, will become even more passive.

Seto Kaiba said in an almost commanding tone, "Lead the way."

With a gentle wave of its hand, Disruptor Powder opened a door in front of the Seahorse Brothers.

“Brother…” Kaiba Keihei was a little worried.

Seto Kaiba took his hand and smiled gently: "Don't be afraid. I told you, no matter what happens, as long as I'm here, you'll be fine."

"Okay!" Keihei Kaiba nodded, and followed Seto Kaiba and Disruptive Pink through the large door...

The light gradually dimmed from its dazzling intensity.

After guiding the two to the designated space, the disruptive fan left on its own.

Surrounded by dreamlike memories, Seto Kaiba finally understands everything and learns the truth about why Gosaburo Kaiba would adopt him and Keihei Kaiba.

As one of the world's top arms dealers, Gosaburo Kaiba has always adhered to a brutal elite education for his children.

To motivate his only son, Noa, Kaiba Gosaburo, he decides to find an adopted son to inspire Noa, much like adding a catfish as a hunter to a tank to help a sardine grow better.

However, what Kaiba Gosaburo never expected was that after he finally found a replacement who looked similar to his biological son and had similar talents, Kaiba Noa would die unexpectedly in a car accident.

Unable to accept all of this, Gosaburo Kaiba used KC Corporation's top technology to preserve Noa Kaiba's soul in a virtual world, hoping that one day, with technological advancements, he could revive his beloved son.

But not long after, Seto Kaiba launched a rebellion within the company, seizing all of his shares in just a few months, turning Gosaburo Kaiba from a world-class arms dealer into a penniless pauper in an instant...

These memories almost all revolve around that evil man—Gozaburo Kaiba.

The changes at KC Company were also revealed in great detail during the recollection...

However, when he actually witnessed the methods his brother Seto Kaiba used to seize KC Corporation, Keihei Kaiba, standing to the side, suddenly froze. A sudden wave of sadness and grief washed over him. His eyes widened, and he murmured, "So that's how it is... Brother... He used me..."

Chapter 143 Is this something you can learn just because you want to?

In the process of taking over KC Corporation's shares from Gosaburo Kaiba, Seto Kaiba devised a bold and crucial plan, the most important element of which was his younger brother, Keihei Kaiba.

Seto Kaiba firmly believed that no matter what happened, Keihei Kaiba would stand firmly by his side. So when Gosaburo Kaiba discovered that he was trying to take over the company, Seto Kaiba cruelly drove Keihei Kaiba away from him.

Keihei Kaiba holds about 10% of the shares in KC Corporation. After being abandoned by his brother, Gosaburo Kaiba extended an olive branch to him and brought him into his camp.

After a fierce battle, Gosaburo Kaiba finally defeated Seto Kaiba by less than 10 percent. But just as he was about to expel his treacherous adopted son, Keihei Kaiba, who had been abandoned, betrayed Gosaburo Kaiba and resolutely chose his brother.

This change turned Kaiba Gosaburo's less than 10% advantage into a disadvantage of more than 10%! It also turned him from a winning position into a defeated prisoner in an instant.

In the end, Seto Kaiba completely seized control of KC Corporation, while Gosaburo Kaiba suffered a complete defeat and died in despair shortly after losing everything.

The entire plan was flawless.

However, the core of the plan is extremely cruel, as it is based on Keihei Kaiba's feelings for Seto Kaiba.

It exploited Kaiba Keihei's dependence on and affection for his older brother...

Behind that door, Kaiba Keihei, having learned everything from his memories, had tears welling up in his eyes. He had never imagined that his brother would use him...

At that moment, his surroundings began to darken. Bewildered and sorrowful, he stood there, completely unaware that, under Noah's influence, he had been separated from Seto Kaiba and was slowly sinking into a swamp-like abyss...

"Keihei! Keihei!!" Seto Kaiba shouted anxiously as his younger brother's figure kept disappearing, and tried to chase after him, but an invisible wall separated the two brothers, and no matter how much he shouted, Keihei Kaiba could not hear him.

The world of memories collapsed into a single point of light. In the void of the electronic world, Noa Kaiba smiled contemptuously and appeared in front of Seto Kaiba.

"Tsk! What exactly do you want?!" Seto Kaiba's eyes blazed with fury.

Kaimania smiled and said, "The reason for starting this competition is simply to give the five giants a chance for revenge, and at the same time to prevent those meaningless people from interfering with our duel."

"With your strength, the five giants can't stop you at all, so I don't want to waste any more time."

"Seto, at this moment, only the two of us remain in this space."

"If you want to save your brother, then defeat me in a duel!"

Seto Kaiba's gaze turned cold, and a Duel Disk appeared out of thin air on his arm: "Ha! Right now you're nothing but a soulless ghost without a body! Everything you're doing right now is a waste of time!"
