Hum—"

In an instant, invisible spiritual power ripples spread out from Yi Shu's hand.

Thundercloud Bird closed his eyes, sighed in his heart, completely let go of the spiritual power protection, let Yi Shu's spiritual power enter his sea of knowledge, and signed a spiritual contract with him that could only be signed by mutual consent.

At the moment when the spiritual contract was signed, the Thundercloud Bird, which was still a little sluggish, suddenly widened his eyes.

The powerful force seemed to pour into his body like a steady stream, and he couldn't help but stretch his wings.

"Crackling—"

Wisps of purple lightning burst out from between the wings of the thundercloud bird, enveloping the surrounding water vapor and dust, forming a huge thundercloud that enveloped his entire body.

In the thunderclouds, the body of the thundercloud bird with its wings stretched continued to expand, growing from ten meters to eleven meters in a moment, and then rapidly expanded to twelve meters and thirteen meters......

"Is this the energy feedback of the equal contract?"

Yi Shu looked thoughtfully at the expanding beast in front of him.

The reason why he wanted to try contract magic beasts was to see the effect of these spiritual contracts.

According to the means of the two spiritual contracts he mastered, the master-servant contract was mainly to unilaterally plunder the power of the contract monster and draw the power of the other party into himself, while the equal contract was more like a symbiotic agreement, where both sides of the contract were mutually beneficial, and each had a part of the energy flowing to the other party, so as to achieve a win-win situation of mutual strengthening.

There are pros and cons to both contractual instruments.

The former can be forcibly enslaved, but the enslaved monsters will be weakened to varying degrees depending on the strength of resistance, and if they resist desperately, they can only enslave a walking corpse without consciousness in the end, so when most psychic mages use the master-servant contract, they will choose those creatures that have a great gap with their mental power, or use some magic and potions that weaken mental resistance.

As for the latter, it seems to be mutually beneficial, but in fact it is more powerful for short-lived species.

In the case of Thundercloud Bird, it is actually a great loss for him to sign an equal contract.

Because the lifespan of the Thundercloud Bird is at least more than 100,000 years, and humans are notoriously short-lived, if they don't use any life-prolonging magic or saint-level potions, even the lifespan of a peak saint will not exceed 5,000 years.

Signing a contract with a strong human being, for the thundercloud bird, is equivalent to a loss of 50,000 years of life.

Such a loss-making transaction, in the absence of a threat to life, the thundercloud bird will never do it.

This is also the reason why the Thundercloud Bird still seems to be languishing when it signs an equal contract with a strong person like Yi Shu.

A human powerhouse who is suspected of being a saint may indeed help him increase his strength in the early stage of signing the contract, but how can a little strength compare to that lifespan of tens of thousands of years?

- Thundercloud Bird thought so at first, until the power feedback from Yi Shu's side poured into his body.

What is the lifespan of 50,000 years, and what is compared to the power that pours into the body?

Take it, take it all!

The thundercloud bird stretched its wings, craned its neck, and let out a long howl with excitement on its face.

The surging power poured into his body along the dark connection, frantically strengthening his whole body.

Every inch of muscle, every feather, and even the tiniest fibers on each feather have become tougher and stronger under the strengthening of this force, and in just five minutes, the body of the thundercloud bird has grown from ten meters to a full thirty-five meters, and the wingspan is more than eighty meters, completely surpassing all the ancestors of the thundercloud bird that have been mentioned in the classics.

Feeling the unprecedented surging power in its body, the thundercloud bird let out an excited chirp.

As a high-IQ person who is also rare among the thundercloud birds, he has a clear understanding of his growth rate.

With a body length of 35 meters, a wingspan of 80 meters, and such an exaggerated body, let alone 50,000 years, even if he is given another 500,000 years of quiet development, it is absolutely impossible to have such a powerful force!

Thinking of this, Thundercloud Bird's gaze towards Yi Shu became intimate.

However, the rapid growth rate brings about the depletion of mana that does not match the body.

In order to alleviate the pain of the mana drying up, the thundercloud bird opened its beak engraved with purple stripes and swallowed purple thunder and lightning, and the thunderclouds covering its whole body poured into its wings as if they were returning to the sea.

But even so, the mana reserves in his body still seemed a little expensive.

No way, who let all the energy that Yi Shu fed back to him be used to improve his body and spirit?

Thundercloud Bird looked down at Yi Shu, who was closing his eyes to receive energy, hesitated for a moment or two, and finally cautiously leaned out his spiritual power, trying to communicate with Yi Shu through the connection of the equal contract.

But what Thundercloud Bird never expected was that his spiritual power was completely rejected by Yi Shu.

How is this possible?

Aren't they in a contract of equality?

Thundercloud Bird's face was full of disbelief, but he had to accept the reality.

Unable to notify and dare not disturb, the thundercloud bird could only throw Yi Shu here first, spread his wings and fly high, submerged into the clouds, and controlled the purple lightning and thunderclouds, constantly surging among the layers of dark clouds.

"Boom—"

Lightning and thunder thundered in the sky, and countless purple thunderbolts brewed among the clouds.

The thundercloud bird hovered in the dark clouds, absorbing the purple thunder and lightning in the clouds in the most brutal way.

Countless thick thunderbolts crackled inward on his body, absorbed by the purple wings at the edges, revealing a strange metallic luster under the washing of the power of thunder.

At the same time, Yi Shu was also absorbing the strange energy that poured into his body.

Although this energy was not powerful, the essence of the energy was extremely high, and after pouring into Yi Shu's body, he immediately felt a sense of soul sublimation and fulfillment.

Yi Shu understood that this should be the lifespan he got from the Thundercloud Bird.

Different from the feeling of warming cells when basking in the sun, it was his spirit and soul that were warmed this time.

After all the energy transmitted into the body was digested, Yi Shu compared the gap between before and after obtaining the lifespan, and suddenly found that his original lifespan was only about 800 years.

This is due to the feedback of the Potential Realm Martial Arts and strong spiritual power, and it has nothing to do with the abilities of the Kryptonians.

In this regard, Yi Shu had already expected it, originally he planned to take some life-extending elixir from the movie in a few years, but now with this method, at least there is no need to worry about lifespan for tens of thousands of years.

As for tens of thousands of years later, Yi Shu didn't think that he would still be worried about lifespan at that time.

In addition, Yi Shu also obtained an ability similar to the power of thunder from the Thundercloud Bird.

I thought that this thunder power would be repelled by cells like magic power, but what Yi Shu didn't expect was that the cells in his body actually accepted this energy under the traction of spiritual power, and reacted violently with it, and finally Yi Shu obtained an ability to convert the energy stored in the cells into purple thunder and lightning.

This ability is not magic, but more like a supernatural ability and a supernatural power.

It is attached to the equality contract, and once the thundercloud bird dies, or the equality contract is dissolved, it will cause Yi Shu to lose this ability to control the purple electricity.

After digesting these spiritual power messages, Yi Shu finally opened his eyes and looked at the sky.

As if sensing Yi Shu's gaze, a cheerful chirp came from the sky, and the figure covering the sky and the sun was bathed in thunder, and a huge head poked out of the dark clouds, looking at Yi Shu from afar.

Looking at the thundercloud bird's purple-red gradient eyes, as well as the ever-changing thunder around him, Yi Shu realized in his heart, and stretched out a hand thoughtfully, aiming at the sky.

In an instant, the purple thunder in the dark clouds surged wildly, converging together under the control of the invisible force, turning into a purple thunderbolt the size of a bucket and crashing down, falling into Yi Shu's palm.

"Crackling—"

A crackling arc burst sounded from the palm of his hand.

Yi Shu looked at the solidified purple lightning in his hand with a slight smile, and as soon as he let go of his hand, the solidified purple thunder instantly disintegrated, turning into countless tiny purple arcs escaping in the air.

Yi Shu clapped his hands, felt the slight numbness in his palms and nodded.

How to say it, although the power is a little unsatisfactory, but it is more or less an additional means.

What's more, this purple thunder also has the attribute of spiritual power attack, and with a little research, maybe you can also broaden your means and application of mental power.

Flying high in the air, bathed in purple lightning and thunderclouds, Yi Shu chuckled and stretched out a hand.

The giant bird with thunder shadow in the clouds immediately responded, only to see him carefully hang his head, leaned into Yi Shu's palm, and rubbed it with an extremely affectionate attitude, as if he was currying favor with Yi Shu.

A smile appeared on Yi Shu's face.

But then, he noticed something was wrong.

The transfer of energy to each other has ended, but less than one percent of the energy stored in the cells in his body has gone, which is far from the fifty percent described in the equal contract.

It stands to reason that the Thundercloud Bird should still be able to improve.

Yi Shu asked the question in a puzzled tone.

Thundercloud Bird looked ashamed and whispered with some embarrassment, "This is because my body has reached the limit of growth, and if I want to receive your power again, I must break through to the Holy Stage."

Yi Shu raised his eyebrows, looked at his thirty-five-meter body and said in surprise, "You're not a saint yet?!"

You must know that the Thundercloud Bird of the Holy Rank back then was only eighteen meters long, and the data was only half of its own, and the actual difference in appearance and size was even greater.

Compared with today's 35-meter-tall behemoth, the top of the thundercloud bird back then was a baby that had not yet begun to develop.

In this regard, Thundercloud Bird's explanation was that the reason why the Saint-level demonic beasts were Saint-rank demonic beasts was because they condensed the Saint-rank demonic crystals, and as for the size and the like, they were actually secondary factors.

But then again, although body size is not equal to the realm, it is closely related to combat power.

For Warcraft, the larger the size, the more magic power it can hold, and the stronger its combat power will be.

After growing into his current appearance, Thundercloud Bird patted his chest and said with great confidence that he should not have much of a problem with the newly promoted human saint now.

The combat power is equal to the realm of the new saint......

Yi Shu nodded, and then asked, "The condition for the success of the equal contract is the complete exchange of energy, but now that this process is only half completed, how should it be calculated?"

Thundercloud Bird didn't know this question either, but that didn't stop him from showing shame again.

Due to the excessive difference in strength, the equal contract between the two sides was not completed, which was unheard of in the Thundercloud Bird's cognition, and if it was known by other clansmen in the clan, I don't know how to laugh at his weakness......

No, I should say my partner...... No, the boss is too strong.

Thundercloud Bird quietly looked at Yi Shu, and saw that he was thoughtful, so he blushed and said with some twist, "Or, let's change the master-servant contract?"

"......" Yi Shu was stunned at first, and then his face was full of surprise, "Aren't you very resistant?"

Thundercloud Bird hurriedly shook his head, joking, it depends on who the other party is or not.

If it were just a sage or a demigod who wanted to be his master, he would rather die than give in.

But the one in front of him, where can a sage or a demigod summarize it simply.

Just the energy transmitted by the equal contract allowed him to break through the shackles of the race and grow to the limit of the thundercloud bird, not to mention a demigod with such great power, even a god without authority can never do it!

Yi Shu thought thoughtfully: "I heard that thundercloud birds yearn for the sky and freedom."

Without thinking, the Thundercloud Bird said, "But you are greater than the sky!"

Description: "......"

After pondering for a moment or two, Yi Shu still shook his head and did not modify the contract.

Although the master-servant contract can allow him to gain a greater lifespan bonus, in this case, the Thundercloud Bird's strength cannot be increased rapidly, and can only be used as a consumable and his lifespan extraction source.

In this way, it is not as useful as an equal contract.

As for the so-called equality of the contract of equality, it is obviously a joke in today's circumstances.

The process of energy exchange has not been completed, resulting in the inability of many privileged thundercloud birds in the equal contract to be used, such as the spiritual power communication of Fang Cai, and the thundercloud bird is completely unusable.

But on the other hand, Yishu can easily use these privileges.

To some extent, before the Thundercloud Bird completely receives the power of Yi Shu, they can only sign this unequal contract of equality between them......

"Oh yes, I haven't asked your name yet."

"My name is Til Sander Hamis...... Zidian, just call me Tyr."

"Till, good name, how old are you?"

"Thirty-four."

Sure enough, he is not yet an adult.

The Thundercloud Bird is an adult at the age of fifty, and the age of thirty-four is about fifteen years old for the Thundercloud Bird, which is about fifteen years old for humans, that is to say, the Thundercloud Bird he caught is actually a genius who has been promoted to a legend at the age of fifteen!

Yi Shu smiled with satisfaction, and then asked, "Can you get smaller?"

Thiel nodded, "Not before, but now it can."

After saying that, countless purple thunderbolts bloomed on Tiel's body, and his huge mountain-like body continued to shrink in the purple thunder, and soon shrank to a size only the size of a parrot.

Yi Shu held out a hand, and Til immediately flapped his wings and flew up, stepping on Yi Shu's fingers to meet him.

Yi Shu said with a serious expression: "From now on, you will be my first contract demonic beast, now tell me, are there any other legendary or more magical beasts around here?"

「……？」

Till tilted the bird's head, and a big question mark seemed to pop up around him.
