In Nangong Nayue's villa, Nangong Nayue held a letter with a solemn face and handed it to Ling Yun.

"Lingyun, look at this letter!"

Ling Yun took the letter, and after reading it carefully, his brows couldn't help frowning: "That Yue-chan, who gave you this letter?" ”

"It was given to me by Vatra's subordinate, Tebias Gakan, that guy is Vatra's henchman, this letter can't be fake!" Nangong Nayue said.

"Heh, this guy Vatra has the courage to give me a war letter, isn't the last few lessons enough?" Ling Yun raised his brows slightly. "Or is this guy finding something to rely on, and he thinks he can compete with me."

"Anyway, there is a strange aura everywhere in this challenge letter, or I will help you directly refuse." Nangong Nayue said worriedly.

"No, if I refuse, Vatra, who is desperate to fight, will do something!" Ling Yun shook his head slightly. "Well, let me see what benefits this guy has gotten to dare to challenge me!"

"Then I'll go with you!" Nangong Nayue said.

"No, the situation on Xianshen Island is unknown now, and you still have to sit here!" Ling Yun said. "By the way, you go and inform Xiao Gucheng that he must protect Blue Feather and Shallot for a period of time!"

"Let him protect Blue Feather shallots?" Nangong Nayue raised her eyebrows slightly. "Why?"

"If there is anything that Vatra can rely on, the biggest possibility is the strange power on the island of the string gods." Ling Yun said slowly. "I've done experiments, and this kind of power can make the power of the demon race continue to grow, and it seems that there is no upper limit."

"But what does this have to do with protecting Blue Feather Shallots?" Nangong Nayue asked.

"Now this kind of power on the String God Island, the most likely is the power of Cain, the ancestor of the demon race, and the title of Blue Feather and Shallot, you shouldn't know it!"

"I remember that the god Hades used to call her 'Cain's witch'?"

"If I'm not mistaken, it's very likely that Cain's power is hidden in Blue Feather Shallot's body. Vatra's character, he will never let go of this kind of power, there is Xiao Ancient City, and the safety of Blue Feather and Light Onion can be greatly guaranteed. Ling Yun said.

"I see." Hearing Ling Yun's words, Nangong Nayue suddenly became serious.

"I'll go to the Tomb of the Sea first and see what the hell this guy Vatra is in!" Ling Yun got up, and a spatial magic circle instantly appeared around him.

"Master, where are you going?" Luo Yexi walked in from outside the door, just in time to see Ling Yun unfolding the spatial magic array.

"I'm going to see Vatra, Yexi, you go to Caihai Academy, protect Xia Yin!"

"Master, what's wrong?" Luo Yexi's face suddenly became serious.

"There's nothing going on yet, it's just that some people want to do something." Ling Yun said. "We are prepared to be better able to respond when there is an emergency."

"What about you, Master?" Luo Yexi asked.

"Me? I'm going to meet the guy who's going to make trouble for a while! Ling Yun waved his hand and said.

"Then Master, be careful." Luo Yexi nodded slightly, and then left here quickly.

Ling Yun nodded at Nangong Nayue, and then disappeared into the spatial circle in a flash.

On the sea not far from Xianshen Island, a huge cruise ship floated quietly, and Ling Yun's figure appeared in the sky, looking at the ocean tomb below.

On the deck of the Tomb of the Sea, there is a round table and two chairs, and a bottle of red wine is placed on the table. Vatra was sitting in a chair with a crystal goblet in his hand with red wine in it.

"Vatra, you want to challenge me?" Lingyun landed on the deck and looked at Vatra in front of him.

"You're finally here, Lingyun!" Seeing Ling Yun appear, Vatra's eyes lit up suddenly, and the magic power around her began to fluctuate.

"Huh?" Ling Yun glanced at Vatra faintly, and then sat down in another chair.

Vatra let out a muffled snort, her body shuddered, and a little red wine spilled out of her glass.

"It's worthy of Ling Yun, a vampire without any superiors, this feeling makes me feel like I've seen the Forgotten War King. To be honest, I'm genuinely curious about your identity. Sometimes I can't help but wonder if there are not just four True Ancestors in this world, but five, and this last True Ancestor is you! Vatra's eyes burned with frantic intent.

"If you invited me here with a challenge book just to say your so-called conjecture, it would be a real waste of my time." Ling Yun picked up a goblet from the table and poured himself a glass of red wine.

The red wine that can make Vatella, a vampire, look good, is naturally not an ordinary commodity. Ling Yun squinted his eyes and shook the red wine in his glass slightly. The aristocratic temperament that naturally exuded on his body actually suppressed the Vatra on one side.

A bright light flashed in Vatra's eyes, and he was even more curious about Ling Yun's origin, after all, this kind of aristocratic temperament is not something that ordinary families can cultivate, nor can it be formed overnight. It is absolutely impossible for such an outstanding person to be unknown in the upper class, but he has never heard of Ling Yun's name. Of course, even if he wanted to break his head, he wouldn't guess that Ling Yun was not a person who belonged to this world.

"To be honest, I'm getting more and more curious about you now, and I should say that my expectations for you have surpassed Xiao Gucheng." Vartra's eyes were filled with war. "The Forgotten War King is my old man, and it's not good for me to do anything with him. Xiao Gucheng, the Fourth True Ancestor, is just a half-ass, so I can't be interested. The other two True Ancestors, I can't challenge them because of my identity. It wasn't until you showed up that I realized that there was an opponent like you in this world who could make me excited. ”

Vatra let out a maniacal laugh, the magic on his body surging, and he raised his hand to summon the beast.

"Bang-" At the moment when Vatra raised his hand, a trace of fierceness flashed in Ling Yun's eyes, and a terrifying sonic boom cloud instantly exploded around him. The powerful force instantly crushed the table in front of him and bombarded Vatra, who was sitting across from him.

Under the powerful bombardment of Lingyun, Vatra flew upside down like a cannonball, piercing the building at the top of the Ocean Tomb, shattering the railing on the side of the ship, and then dragging a sky-high waterline on the sea.

A blow blasted Vatra away, and Ling Yun slowly got up. made such a powerful attack, but the crystal goblet in his hand was nothing at all, and the red wine in the cup did not even spill at all.

On the sea in the distance, terrifying magic power rose into the sky, and two huge snake-like beasts appeared on the sea, letting out a high roar at Ling Yun.

Ling Yun threw the goblet in his hand, and his body instantly turned into an afterimage, rushing towards the place where the snake-shaped beast was.
