In terms of potential, the Thunder Crystal Beast King is greater than the Immortal Bird King, but in terms of strength, the Immortal Bird King is much stronger than the Thunder Crystal Beast King.

If the Immortal Bird King can be used for his own use, then the overall strength of Lin Feng's team will be improved a lot, and people will dare not ignore it even more.

But the more powerful the demon beast, the more arrogant it will be, and it will never easily surrender to others.

What's more, the Immortal Bird King is a unique mutated immortal bird in the Heavens and Ten Thousand Worlds, and it is an extremely rare mutated super divine beast, with a high level of spirit, far beyond the comparison of ordinary demon beasts.

Lin Feng was already prepared to fail, if the Immortal Bird King refused, then he could only choose to kill him.

Although each mutated super divine beast is extremely precious, killing one will reduce one, but if there is already a feud and the other party refuses to surrender, then in order to prevent future retaliation, Lin Feng has to choose to kill it and strangle the threat in the cradle!

The Immortal Bird King trembled all over, and a painful ** came out of his mouth.

Hearing Lin Feng's question, it struggled for a moment, turned its head, and cast a weak gaze on Lin Feng.

"I, will, will!" said the Immortal Bird King intermittently.

Lin Feng glanced at it in surprise, he never expected that this extremely powerful demon beast would be willing to surrender to him!

However, he didn't think much about it, since the Immortal Bird King was willing to surrender, then he had no reason to get rid of the other party again.

"I'm going to lay out a monster contract next. Lin Feng said, first using the power of the law to set up a layer of enchantment, and then slowly released the weak yuan force in his body.

To arrange the demon beast contract, you need to use Yuan Force, with the Yuan Force of the Lin Feng Supreme Limit, it may be regarded as a top-level existence in the Xingfeng plane, but in the Suiyang Realm, it is the existence at the bottom, and if you pull one out casually, most of them are stronger than him.

The Immortal Bird King who was still struggling. Suddenly, his eyes widened.

It looked at Lin Feng in shock: "Why...... Reach...... Respect...... Limit. ”

It never expected that the human race in front of it, which made it feel inexplicably dangerous, was actually just a Supreme Limit! Moreover, even powerful beings like the Thunder Crystal Beast King and Nuno were all looking forward to this Supreme Limit!

This is undoubtedly the biggest joke in the world!

But this joke really happened right under its nose!

It was stunned, and its brain went blank.

"Alright. Lin Feng had already arranged the demon beast contract, "Drop a drop of your blood in the middle of this contract." ”

The Monster Contract can only be made if both parties are willing, but if either party resists or is unwilling, the contract will fail.

The Immortal Bird King was awakened and slowly came back to his senses. It hesitated for a long time, but finally forced out a drop of blood.

"Hum~"

After fusing the blood of Lin Feng and the Immortal Bird King, the contract array suddenly flourished, and trembled slightly.

Soon, the contract was completed.

The contract array transformed into a transparent existence and split into two parts, one into Lin Feng's mind and the other into the mind of the Immortal Bird King.

"This is the ultimate healing elixir. Lin Feng took out a top-grade healing elixir and threw it to the Immortal Bird King. "Hurry up and refine the medicinal power. ”

This was given to him by Ge Tianfang at the beginning, but he didn't expect that before he could use a single one, he had already realized the law of life to the point of Dacheng, and he no longer needed healing pills.

The Immortal Bird King opened his mouth and swallowed the best healing elixir. Quickly refining its medicinal power, the injuries on his body slowly recovered.

Nuo Nuo pouted on the side and said, "Boss, why do you want to save it? and waste a superb healing elixir!"

The Thunder Crystal Beast King doesn't speak, this kind of thing. He didn't dare interject.

"Anyway, it's also a mutated super beast, if it can be used for its own use. It's better than killing after all. Lin Feng explained.

"Is the mutant super divine beast very powerful?" Nuno said disdainfully, "Haven't you been beaten half to death by me?"

Lin Feng smiled dotingly: "Yes, yes, or our family Nuo Nuo is the most powerful." ”

"Hee-hee...... Nono smiled, "That's pretty much it." ”

After appeasing Nuo Nuo, Lin Feng then set his eyes on the Thunder Crystal Beast King: "Lei Lie, I will give you a choice now, whether to continue to be my soul slave, or to abolish the soul contract and sign a new demon beast contract, you can choose for yourself." At the end, he added, "Don't worry, no matter what you choose, I won't blame you." ”

Soul slaves can only surrender unconditionally, but their loyalty may not be very high, while monster contract partners must give all their loyalty, but they can share a lot of benefits.

There is only one chance, if the Thunder Crystal Beast King refuses, then if he wants to sign a demon beast contract with Lin Feng in the future, Lin Feng will not agree again.

Fortunately, although the Thunder Crystal Beast King was clumsy, he was very smart at the critical moment.

He didn't hesitate, and said directly: "Master, I am willing to sign a demon beast contract!"

For demon beasts, signing a demon beast contract is undoubtedly a better choice, at the beginning it was because there was no choice, but now that there is room for choice, a fool will refuse.

Lin Feng was not surprised by the choice of the Thunder Crystal Beast King, he nodded, and immediately began to arrange another demon beast contract.

Each ground cultivator can have three demon pets.

Nuo Nuo and Lin Feng signed an equal contract, but it is also a kind of demon beast contract, which can be regarded as the first demon pet.

The Immortal Bird King and the Thunder Crystal Beast King signed an ordinary demon beast contract, which can be regarded as completing Lin Feng's remaining two places.

In the future, if he encounters any powerful demon beasts, Lin Feng will no longer be able to sign a demon beast contract with them.

However, with the two demon pets of the Immortal Bird King and the Thunder Crystal Beast King, Lin Feng can't look down on other demon beasts, the Thunder Crystal Beast King has unlimited potential, the Immortal Bird King has strong strength, with such two demon pets, Lin Feng doesn't need to ask for more.

After the contract was completed, Nuno instantly swept to the side of the Thunder Crystal Beast King, and without waiting for the Thunder Crystal Beast King to react, he gently patted the Thunder Crystal Beast King's shoulder, with an old-fashioned appearance: "I am the boss's first demon pet, and I signed an equal contract, so in the future, you will be under my control, the boss is not here, you have to listen to me in everything, understand?" He couldn't wait to start training this new little brother.

"Yes. The Thunder Crystal Beast King shuddered in fright, and then said honestly.

Seeing Nuono's strength, how dare he resist.

Lin Feng couldn't cry and laughed, and said, "Okay, Nuonuo, don't bully Lei Lie." ”

"Boss. I didn't bully him. Nuno blinked innocently, and then said righteously: "I'm training him, lest he be disobedient and miss our big things in the future." ”

At this time, the Immortal Bird King recovered a little from his injuries and struggled out of the brink of death.

It slowly opened its eyes, flapped its wings with difficulty, and its gaze stopped on Nuo Nuo, and it staggered to the other side of Lin Feng: "Master." ”

"How's the recovery?" Lin Feng said with concern.

Although he used to be an enemy, now that the Immortal Bird King has become his own demon pet. Then Lin Feng naturally hoped that the Immortal Bird King would recover soon.

"I've recovered a little bit, and I'm moving well. The Immortal Bird King said cautiously: "But if you want to fully recover, it will take at least half a month, and during this half month, I can't exert my full combat strength." ”

Lin Feng nodded: "Okay, then you can cultivate well, and when you recover, you will come to help me." ”

"Thank you hosts. ”

"Nono, Thunder. Let's go. Lin Feng waved his hand and sent the Immortal Bird King into the Sword God Palace, and then said to Nuo Nuo and Lei Lie.

Nono looked forward to it, "Are we going back?"

Lin Feng nodded and said, "The war has begun, we have delayed a lot of time here, I hope it's too late to go back now." ”

"It's going to be in time!" Nono said excitedly, "This time." It's my turn to show off my skills!"

Entering the Sword God Palace, Lin Feng drove the Sword God Palace to fly to the shallow sea area of the Thunder Fog Sea at high speed.

Nuo Nuo put on a boss style, and slowly trained the Thunder Crystal Beast King and the Immortal Bird King, the two demon pets that Lin Feng subdued. Soon became Nuono's little brother, who was trained to be obedient, and he wanted to show his loyalty with death.

Jing Ting, Huang Wenbing and Bai Chufeng looked worried. Silently staring at the clouds in mid-air.

"Nono, stop for a moment. While controlling the Sword God Palace, Lin Feng said to Nuo Nuo behind him.

"What's wrong, boss?"

"Let Lei Lie and the Immortal Bird King come over first, I have something to ask them. ”

"Oh, okay. You two, go over here, the boss has something to ask you. Nono waved his hand.

When the Thunder Crystal Beast King and the Immortal Bird King came to him, Lin Feng asked curiously, "How did you two fight?"

The two demon pets glanced at each other, and then the Thunder Crystal Beast King handed the space ring to Lin Feng, and said respectfully: "Master, I found a material in the Immortal Bird King's lair, and while it was not there, I stole this thing, but it didn't take long for it to be discovered, and it was hunted down for a long time." ”

"What material?" Lin Feng took the space ring and didn't check it immediately, but continued to ask.

"I don't know. The Thunder Crystal Beast King replied angrily.

Lin Feng shifted his gaze to the Immortal Bird King: "Tell me." ”

The Immortal Bird King showed a humanized expression, and lowered his head in embarrassment: "I don't know what material it is. ”

Lin Feng was stunned for a moment, and wondered, "You don't know what it is?"

After a pause, he asked again, "Then do you know what it does?"

The Immortal Bird King still looked dazed: "I don't know." ”

"......" Lin Feng held back for a long time before he said depressedly: "Since you don't know, why are you desperately chasing and killing Lei Lie?"

Hearing this, the Immortal Bird King said as a matter of course: "Although I don't know what kind of material it is, I know that it must be a good thing, because I have eaten a fruit before, and then I evolved into the Immortal Bird King, and this thing, the aura emitted is exactly the same as the breath emitted by the fruit I ate at the beginning, they must be the same level of things." ”

"And what's going on?" Lin Feng said in surprise.

The Immortal Bird King nodded, obviously, it was impossible for it to deceive Lin Feng.

With a hint of curiosity, Lin Feng's spiritual power probed into the space ring, and there was only one thing in it, which was a branch.

"Is this something?" Lin Feng asked in astonishment as he took out the branch.

The Immortal Bird King and the Thunder Crystal Beast King nodded one after another.

"This thing is really so amazing?" Lin Feng was a little suspicious, looked at it carefully, and remembered the breath that the Immortal Bird King said, he couldn't help but sense it carefully, and this sense suddenly found a hint, "This breath ......" he muttered, his brows furrowed slightly, "Why does it feel so familiar?" He vaguely remembered that he had been in contact with it, and even had it many times.

The next moment, his eyes suddenly shrank: "It's the will of the Holy King!"

He remembered! )
