Could it be that this old man who had been suffering from severe injuries was a hidden Martial Saint? His guess was reasonable, because he could feel that the two energies within Uncle Fu's body had been tangled for many years, yet they were still so strong and had a holy aura. When Uncle Fu was at his peak, he was definitely not weaker than the Martial Saint.

"Your Highness, how is it?" Yan Lu asked, his words carrying a trace of probing, and also a trace of anticipation.

He had felt Uncle Fu's power back then. If he could expel the demonic energy from his body, then the Battle King's Manor would gain a powerful boost.

They didn't know where Uncle Fu came from, but he was saved by Ling Zhan twenty years ago on the Spiritual Demon Battlefield.

Later on, in order to repay his debt of gratitude, Uncle Fu stayed at the War King's Manor. It was precisely because of this old man that he had been able to protect Ling Yun from those mysterious people fifteen years ago.

They all knew that Uncle Fu had been severely injured by the demons. The demonic energy had invaded his body, almost causing him to lose his life. When he was saved by Ling Zhan at that time, his body was covered with demonic qi and he had already fainted.

However, that demonic energy was too strong to expel, and for some reason, Uncle Fu told them not to look for a high-level magic refiner to treat him.

"Things are not looking good!" Lingyun lightly looked at Uncle Fu, and said: "Demonic Qi is entering your body, although you can barely suppress it with your great strength, but you cannot completely suppress it. After all these years, that demonic energy has become more and more powerful, and the restlessness has become more and more powerful. You can no longer control the situation.

Moreover, you cannot use spiritual energy, otherwise the suppression on the demon qi will be weakened. You should have been inside the body of the demon qi all these years. He must have used spiritual qi more than once, right? Your blood has been devoured by the demon qi and you are almost exhausted.

Yan Lu looked at Lingyun in shock. He did not expect Lingyun to be able to see through Uncle Fu's body. Also, he had not come in contact with any devil race, how did he know about the existence of devil energy?

Uncle Fu's eyes became sharp and bright. His sharp eyes looked at Ling Yun and flashed with a dangerous glint, faintly revealing a trace of killing intent. His voice was a little cold as he said: "Kid, you know quite a lot, but could it be that you don't know, that sometimes you should pretend to be stupid?"

His eyes that were filled with an ancient aura were as sharp as a falcon's. Staring at Ling Yun, although there was no terrifying aura emitted, there was a soul suppressing pressure, causing the surroundings to seemingly turn silent.

Even Yan Lu's face paled slightly as he looked at Uncle Fu in shock. He did not expect that this mysterious Uncle Fu was even more terrifying than he imagined.

He felt the killing intent from Uncle Fu, his face changed, his body flashed, and he appeared next to Ling Yun. He pulled Ling Yun and instantly retreated, looking at Uncle Fu warily. A faint silvery white light surrounded his body.

He was actually a rare thunder-attribute martial artist. The thunder-attribute spiritual energy turned into numerous lightning serpents that coiled around his arm, condensing into a silver-white broadsword.

Although the latter was considered to be a kindness to the Duke Palaces, he would definitely not agree to do anything that would harm Ling Yun.

Even though he knew that he might not be Uncle Fu's match and would fall because of it, Lingyun was Ling Zhan's child, and he had watched him grow up. In his eyes, people who were like his children, how could Lingyun be harmed?

Ling Yun's expression did not change, with a slight smile on his face, he gently pushed Yan Lu away, and took a step forward, face Uncle Fu without fear.

Although he was surprised at Uncle Fu's sudden aura, it still wasn't enough to scare him. Back then, even when he faced a Titled Martial Emperor, he did not show the slightest trace of fear. Moreover, Uncle Fu was severely injured, so he couldn't make a move.

"Your Highness!" Yan Lu's expression changed as he said worriedly, "What if Lingyun falls? How will I explain this to Ling Zhan?"

"I'm fine!" Ling Yun waved his hand, looked at Uncle Fu, and smiled.

After a long while, Uncle Fu withdrew his gaze. His eyes became cloudy again and his face revealed a helpless smile. He sighed and said, "I'm old and useless. "As expected of her child …"

At this point, Uncle Fu sighed. There was a trace of admiration in his eyes. He didn't continue speaking.

Lingyun frowned. Could it be that this Uncle Fu knew his mother's identity, and his eyes were fixed on her. "Do you know my mother's identity?"

Yan Lu's expression changed. If Lingyun were to find out about his mother's identity and her situation, with Lingyun's character, it was unknown what he would do.

Without waiting for Uncle Fu to speak, he continued, "Your Highness, the Queen is only a peasant woman. She had a difficult time giving birth to you and passed away. You should know this very well."

Ling Yun indifferently looked at him, and looked at Uncle Fu.

"I do know, but why should I tell you?" Uncle Fu shamelessly rolled his eyes and looked at Ling Yun.

"You …" Lingyun was flustered, this old bastard took a deep breath, and calmed his emotions, "What if I can expel the devilish energy that has been plaguing you for many years?"

Uncle Fu's body shook slightly as a ray of light flashed across his eyes. However, it disappeared in a flash, and his eyes were filled with sadness. He looked at Ling Yun, and asked with some disdain: "With just you?"

The devilish energy in his body had been rooted in his body for dozens of years. It had penetrated his flesh and blood, and there was also a mixture of spiritual energy. It was impossible to expel it from his body.

Even if it was a Martial Emperor, there was not much hope. His blood energy was exhausted and his meridians were hardened; he was simply unable to withstand the Martial Emperor's spiritual energy.

Otherwise, he wouldn't have to hide his name and become a housekeeper in the Battle King's Mansion. With his strength, he could become a core elder even in a Holy Land and be highly valued. As long as he paid a price, it was still possible for him to request the help of a Martial Emperor.

Ling Yun, who had his blood sealed, had his Aura Sea set up with a Spirit Devouring Array. How could he do this?

Right now, he could only live with his last breath. At most three years, his suppression of the demon qi would be ineffective. At that time, in order not to be affected by the demon qi, he would find a place where no one could kill himself.

"Ha ha!" Lingyun smiled, and lowered his eyes, gently stroking Mengmeng's soft fur, and said faintly, "If you don't try, how do you know that this prince cannot do it? Could it be that you want to die so badly, and have completely lost all hope in your heart? "

After a while, he gritted his teeth and said, "Very well, this old man will believe you this once. As long as you can expel or suppress the demonic energy in this old man's body, this old man will tell you about your mother's identity. He swore that he would follow and be at your service from now on. "However …"

At this point, Uncle Fu paused. A trace of killing intent burst out from his eyes, and his eyes were filled with coldness as he coldly said, "If you dare to play with this old man, then even if your father has saved my life, I will still kill you!"

"Uncle Fu, His Highness the crown prince was just joking, please don't take it seriously!" Yan Lu's expression changed as he hurriedly stepped forward and shot Ling Yun a look.

Experts had their own dignity. They were not allowed to be toyed with.

He believed that if Ling Yun couldn't do it, Uncle Fu wouldn't let him feel good even if he didn't kill Ling Yun.

Although Uncle Fu couldn't use his spiritual energy, he had to suppress his demonic energy. If he really didn't want to die, then he would release the suppression on the demonic energy. Killing Ling Yun, who was a mortal without any cultivation, was as easy as crushing a little chicken.

Lingyun directly ignored Yan Lu, and upon hearing Uncle Fu's words, his eyes revealed a hint of happiness. The smile on his face became even wider, and he said with a smile: "Okay, hahaha, Uncle Fu, just wait and swear to follow me! I hope that after I expel the demonic energy from your body, you won't go back on your word. "

Even though others could not expel him, it did not mean that he could not do anything about it. Even someone as difficult as Uncle Fu had a way to expel him.

Haha, it seems like he would have a super fighter of the Martial Saint level soon.

"Humph!" Uncle Fu coldly snorted, his face revealing a trace of doubt. Could it be that Ling Yun could really expel the demonic energy from his body? However, he quickly shook his head. How could that be possible?

He looked at Ling Yun with an ice-cold expression. This little fellow, did he think he was joking? At that time, if Ling Yun was unable to do so, he might not kill Ling Yun, but he would definitely not let him off easy.

"I, Ning Tianya, used to rule the world. How could I be someone who goes back on my words?" Hearing Ling Yun say that he wouldn't go back on his word, Uncle Fu's face was full of anger, and felt that he had been humiliated.

At this moment, his stooped body was standing straight and exuding a sharp aura, as if he was a sword that was about to pierce through the heavens.

Ning Tianya?

Yan Lu's eyes were filled with doubt. He had never heard this name before. In the region of the southeast of the continent where the Soaring Cloud Empire was located, there was not a single Unparalleled Holy Land. The strongest there were only eight Holy Lands and a dozen quasi-Holy Lands. The total number of Martial Saints did not exceed fifteen. He had heard of all the names. On the surface, there were more than forty of them, but none of them were called Ning Tianya. Could it be that Uncle Fu was not from the Primal Region of the southeast of the continent?

Ling Yun's body trembled as he looked at Uncle Fu in disbelief. Ning Tianya? Could it be him?

"Lone Sword of Heaven? Ning Tianya?" Ling Yun looked at Uncle Fu with uncertainty and asked.

The Lone Sword of Heaven, Ning Tianya, was from the same era as his previous life. He was younger than him, but he could still be considered to be of the same generation! He could be considered a genius rogue cultivator. He had a proud and aloof personality, but he was the most trustworthy person here. He valued trust more than life.

Not many warriors on the continent had heard of his name.

It was because this person had too much of a personality. He loved to fight against injustice and offended many forces. He would often pass his days being hunted down. In his previous life, Ling Yun had heard of this person by chance, but did not pay much attention to him.

It was said that he was ordinary in the past and didn't have any background. It was only because he had obtained some fortuitous encounters that he had suddenly made a breakthrough. He could be considered a legend now.

When he had fallen in his previous life, Ning Tianya was already a peak Martial Saint. It was not strange for him to become a Martial Saint after a hundred years.

Yan Lu was even more confused. What Solitary Sword of Heaven and Earth? Was there such a person on the continent?

"Have you heard of this old man's name?" Uncle Fu's pupils suddenly contracted. Looking at Ling Yun, his eyes revealed a trace of surprise. Ever since he was injured twenty years ago, he had stayed within the War King's Mansion and had been hiding from the world for many years. The outside world already believed that he had fallen after that battle. This fellow had been staying in a small place like Lingxiao City, so how did he learn of his name?
