What about Zhou Yulin?

On the surface, he didn't seem to have any injuries, but in fact, he consumed much more spiritual energy than he appeared on the surface.

In a sense, if it happens again.

The spiritual energy in Zhou Yulin's body was about to be squandered.

By that time, Zhou Yulin would be of no use even in the Danyuan realm.

If the spiritual energy in a warrior's body is squandered, he will be no different from an ordinary mortal.

After all, only by reaching the legendary realm can one be able to communicate with heaven and earth, absorb the spiritual energy of heaven and earth anytime and anywhere, and transform it into one's own power to supplement and fight.

At their current level, they can only use exercises to practice.

Therefore, Zhou Yulin knew very well that on the surface it seemed that he had the upper hand.

In reality?

Your situation is very dangerous!

When this idea first emerged from Zhou Yulin's mind, he was in disbelief.

He is a warrior at the tenth level of the Spirit Gathering Realm, and one of the top ten geniuses from the outer sect of the Blood Sword Sect!

How could he be forced into such a situation by a little body-refining-level ant?

This is absolutely impossible!

But unfortunately...

this is the truth!

No matter how much he doesn't want to face it in his heart, he must accept it!

This let Zhou Yulin know that Bai Fei must be eradicated!

It's just a mere body refining realm, but it can pose such a big threat.

If it grows up in the future, then that's okay?

He absolutely cannot let Bai Fei leave like this!

Therefore, Zhou Yulin's eyes became particularly fierce, with murderous intent clearly revealed.

In the front, Zhou Yulin just wanted to destroy Bai Fei so as to steal opportunities from him.

But now, since the other party can threaten his life and death, he can no longer continue like this.

Otherwise, it is very likely that he will die!

Therefore, when Zhou Yulin's eyes showed murderous intent, his aura also began to change.

Feeling the change in Zhou Yulin's aura, Bai Fei's eyes darkened slightly and he began to become wary.

He knew that Zhou Yulin planned to use his trump card.

"Bai Fei, I have to admit that your strength is indeed beyond my expectation."

Zhou Yulin looked at Bai Fei, with a solemn tone, and said slowly: "If I give you a little more time, I believe you will definitely become a leader in the outer sect, and even rank among the elites in the inner sect."

Hearing Zhou Yulin's words, Bai Fei did not respond, but quietly listened to Zhou Yulin's bragging.

"But that's it. You should never offend me. If you offend me, you will die!"

When Bai Fei heard this, he immediately wanted to laugh.

Was it someone he wanted to offend?

Didn't you come to trouble him first?

Otherwise, how would we end up in such a field?

However, Bai Fei didn't waste any time talking to him.

For him, Zhou Yulin...

Certain death!

Therefore, Bai Fei just raised his palm slightly, raised it towards him, and said lightly: "Stop talking nonsense and take action!"

Seeing that Bai Fei dared to provoke him like this, Zhou Yulin laughed angrily.

"Bai Fei, I will let you see how big the gap between you and me is!"

After the words fell, Zhou Yulin took a step forward, and then a deep voice sounded in his throat.

"Blue blood transformation!"

"Boom!"

At that moment, Zhou Yulin's body erupted with a ferocious aura.

At the same time, a wolf howl resounded through his body.

Immediately afterwards, his body began to swell.

But in the blink of an eye, Zhou Yulin's appearance changed drastically.

At this moment, Zhou Yulin's height became three meters tall.

His whole body was covered in light blue animal fur, and his hands turned into sharp claws.

The whole head turned into a wolf head.

There was an eerie and ferocious aura emanating from his whole body.

This made Bai Fei's pupils shrink involuntarily, and he murmured to himself: "So... your real trump card is this!"

The changes in Zhou Yulin's body were due to his bloodline!

Blue Spirit Wolf bloodline!

In this world, in addition to the cultivation qualifications, there is another thing that can make a warrior stronger, and that is the power of blood!

This power of blood is also called innate blood.

Because it has been carried since birth!

As you grow, these bloodline powers will gradually awaken and become very powerful!

Of course, some bloodlines are useless, but some bloodlines are extremely terrifying and can destroy the world with just a few clicks!

Therefore, the power of blood is also divided from weak to strong, into Huangpin, Xuanpin, Earthpin, Tianpin and so on.

Each grade of bloodline is subdivided into elementary, middle and upper grades!

And the power of blood is divided into five categories!

A bloodline with elemental categories! For example, metal, wood, water, fire, and earth!

This series of bloodlines can strengthen the spiritual attributes of one's own cultivation.

There is also the bloodline of the weapon category, which can amplify one's own magic weapon, making the magic weapon more powerful!

After that, there is the bloodline of the animal type, which can fundamentally change one's own physique!

Like Yang Ling, whom Bai Fei met before, who had the white tiger bloodline, and Zhou Yulin, whom he was fighting now, who had the blue spirit wolf bloodline!

There are also some plant-type bloodlines, such as flowers, trees, stones, etc.!

And the fifth category, special bloodlines!

However, the reason why special bloodlines are special is that they are too rare!

Even if you search the entire Da Zheng Dynasty, you may not be able to find a few!

Therefore, the five major categories of bloodlines are also called:

Ten Thousand Beast Bloodlines, Thousand Plant Bloodlines, Hundred Instruments Bloodlines, Elemental Bloodlines and Special Bloodlines!

Like Zhou Yulin's blue spirit wolf bloodline, it is a top-grade Xuan-grade Ten Thousand Beast Bloodline.

After using it, it not only changed Zhou Yulin's physical characteristics, but also greatly improved his various functions!

"Shua!"

After using the power of bloodline to transform, Zhou Yulin's eyes flashed with scarlet eyes, and his figure flashed and disappeared on the spot.

By the time Bai Fei reacted, Zhou Yulin had already appeared in front of him.

Bai Fei's face suddenly changed, and he quickly raised the Qingling Sword in his hand and blocked it in front of him.

However, Bai Fei's reaction was fast, but Zhou Yulin's speed was even faster!

"Swish!"

The sharp claws swung down suddenly and grabbed Bai Fei's chest directly.

At that moment, the claw marks were left, and the flesh on Bai Fei's chest was cut, and the bright red blood gushed out.
