I, Godzilla, and Skull Island Sign On for Thirty Years

During the process of concluding the soul contract, the Blade-Spine Jackal King could clearly feel that he seemed to be gradually losing control of his soul.

It instinctively wanted to resist, but it gritted its teeth and suppressed this instinct.

Because it knows that once it chooses to resist, this opportunity will no longer exist.

After a few seconds.

The soul contract is officially concluded!

The body of the Sword-Spine Jackal King was dripping with sweat and was lying on the ground almost exhausted, as if he had experienced a fierce battle.

After the soul contract was successfully concluded, it could clearly feel that there was an additional mark on its soul.

As long as Lin Yuan is willing, he can destroy his soul at any time.

This soul contract can only be canceled by Lin Yuan alone.

In other words, from now on, its life will be completely handed over to Lin Yuan's hands!

However, even so, the Sword-spine Jackal King has no regrets at all!

"Roar!"

The Sword-Spine Jackal King restrained the ferocity in his eyes and roared towards Lin Yuan as if he was loyal!

Lin Yuan smiled and said calmly: "Don't restrain your ferocity, because this is what I value."

"Even in front of me, you can completely unleash your ferocity!"

"Because what I need is not a docile dog, but a ferocious wolf!"

"From now on, you are my wolf!"

"Roar!!"

After Lin Yuan said these words, the Sword-spine Jackal King roared again!

The overwhelming ferocious power suddenly spread from its surroundings!

Looking at the Sword-spine Jackal King in front of him, Lin Yuan couldn't help but smile.

A wolf who should be roaring in the world, why should he restrain his claws and become a dog?

Then, Lin Yuan spoke again: "System, I want to redeem... Shura's demonic blood!"

"Ding, congratulations to the host for successfully redeeming [Shura Demonic Blood], 6 million evolution points will be deducted, and 20 check-in points will be deducted."

The system's prompt tone immediately rang in Lin Yuan's ears.

Although Lin Yuan only had the last 13 million evolution points left, he still spent nearly half of it to exchange for this [Shura Demonic Blood]!

Since the Blade-Spine Jackal King was willing to dedicate his soul to him, Lin Yuan would naturally not treat him badly.

This [Shura Demonic Blood] is the promise Lin Yuan fulfilled to it!

After deducting the evolution points, Lin Yuan immediately had a bottle of demon blood in his hand.

The blood inside was a strange black-red color and very thick. It didn't look like anything good.

Lin Yuan opened the bottle, and a strong smell of blood immediately came out from inside.

Moreover, the Shura demon blood in this bottle does not seem to be as simple as imagined.

Lin Yuan just smelled the smell of blood and felt that the murderous intention in his heart was aroused.

Fortunately, his self-control was quite strong and he quickly suppressed his desire to kill.

Lin Yuan keenly observed that the other giant beasts around him also had strange expressions on their faces.

This shows that he is not the only one affected by Shura's demonic blood.

"Drink it."

Lin Yuan stretched out his hand, handed the Shura Demonic Blood to the Sword Spine Jackal King, and spoke calmly.

The latter was stunned for a moment, then without hesitation he picked up the bottle, raised his head, and drank all the demon blood in the bottle!

For a moment, all the giant beasts couldn't help but fix their eyes on the Blade-Spine Jackal King.

They watched helplessly as the black-red Shura demon blood flowed out of the bottle and flowed into the latter's mouth.

"Cough...cough..."

After drinking the entire bottle of Shura Demonic Blood, the Sword-spine Jackal King started coughing violently!

Not only that, even its eyes began to become bloodshot quickly, and soon turned as scarlet as blood!

A pair of cold wolf eyes were filled with ferocious murderous intent!

Looking at the scene in front of him, King Kong couldn't help but swallow a mouthful of saliva, and subconsciously asked: "Boss, what on earth did you give it to drink?"

Lin Yuan calmly explained: "Asura demon blood, a kind of blood essence extracted from the Shura clan, contains violent killing intent."

"If the user is not strong-willed, there is even a possibility of going crazy."

After hearing this, King Kong couldn't help but be stunned for a moment: "Then you give it a drink."

Lin Yuan said calmly: "I believe that with its willpower, it can sustain it."

You know, under that kind of injury, the Blade-Spine Jackal King still clenched his teeth and dragged the corpse of his prey in front of him.

Just relying on its willpower, Lin Yuan believed that the Sword-spine Jackal King could resist!

Sure enough, although the murderous intent on it was getting stronger and stronger, its aura had begun to gradually become more stable.

It just stood there, its wolf eyes were blood red, and it was breathing heavily.

"well done."

Lin Yuan came to it and praised it lightly.

Moreover, he could feel that the demonic Shura blood it drank was continuously strengthening its body!

In addition to the surging murderous intent, all the muscles around the Blade-Spine Jackal King swelled, looking like pieces of steel!

Strength, endurance, physique, explosive power... everything is growing crazily!

Growth and transformation are always an extremely painful process!

However, Lin Yuan also understood that forcibly suppressing the murderous intention was not a reasonable solution.

Instead of suppressing it blindly, it is better to forcibly release it!

The function of Shura's demonic blood is to make the user continue to become stronger in the process of killing, and finally completely break through their own limits!

The Sword-Spine Jackal King does not have the talents of the Holy Tiger King and King Kong, so it can only fight in this way, risking its life, and fighting for everything in the killing!

Only in this way can it have the possibility of changing its fate against the odds!

Thinking of this, Lin Yuan immediately took a deep breath and said in a deep voice: "King Kong, you and the Holy Tiger King will take it hunting together and practice the abilities you have just acquired."

"However, you should let it fight on its own. Unless it encounters an invincible and powerful enemy, otherwise, even if its life is in danger, you don't need to worry about it."

King Kong nodded and said in a deep voice: "Okay."

"Roar!!"

The Sword-Spine Jackal King took a step forward, with murderous intent shooting into the sky in his scarlet eyes!

Now, perhaps it should be called... Shura Demonic Wolf!

Even Lin Yuan was curious about how far the giant wolf in front of him could grow after swallowing Shura's demonic blood!
