After completely dealing with the Life Rabbit, Chen Jiuge set his sights on the next fierce beast to nurture—the Thunder Bull!

This is a very peculiar fierce beast, resembling an old yellow ox in appearance, with the only difference being its fur. The Thunder Bull has a coat of bright blue fur, looking like a large Avatar.

Most importantly, its ability: it can summon a Heavenly Tribulation!

Though it is just a low-level warrior-class fierce beast, it can summon a genuine Heavenly Tribulation. Initially, Chen Jiuge didn't believe it, until it demonstrated in front of him how to summon a Heavenly Tribulation, making him a believer.

"Rumble rumble"

"Stop striking, stop striking!"

Underneath the dense tribulation clouds, Chen Jiuge kept dodging the purple-black thunderbolts.

The power of this thunderbolt has reached the Golden Blade level. If accidentally hit, it could be very dangerous.

Fortunately, the cultivation of the Thunder Bull isn't high. The ability to conjure such massive tribulation clouds is the result of the entire herd's collective effort.

After ducking and dodging for a quarter of an hour, the tribulation clouds in the sky dissipated. With a warrior-level cultivation, controlling a Golden Blade-level Heavenly Tribulation is already a remarkable feat, but long-term control is still not possible.

"Phew, that was terrifying!"

Seeing the Thunder Bull herd, swaying and looking thoroughly exhausted, a hint of anticipation flickered in Chen Jiuge's eyes: "I wonder what kind of surprise this will bring me!"

"Thunder Spirit Fruit, Heavenly Thunder Water......"

"These fierce beasts from the Heavenly Gift Realm are truly strange. The spiritual materials they cultivate correspond exactly to one attribute of Heavenly Materials and Earthly Treasures, without requiring a mix of other spiritual materials?"

In the True Realm, regardless of the attribute of the spiritual beast, the cultivation requires spiritual materials involving other attributes, as those adept in swimming are often drowned.

It's not that the more extreme the attribute, the better. Sometimes appropriately incorporating spiritual materials of opposing attributes can enhance their fusion and transformation.

"Forget it, perhaps this is the law of different worlds!"

"Zzap bzzap"

"Crack snap"

The process of nurturing the Thunder Bull was quite stimulating. With each spiritual material consumed, these Thunder Bulls emitted a tingly current, giving Chen Jiuge a massage-like sensation from his past life.

As the final spiritual material was consumed by the Thunder Bull, a brilliant light appeared.

The size of the light grew larger and larger, and the Thunder Bull's body expanded rapidly. 𝙛𝒓𝒆𝙚𝒘𝒆𝓫𝙣𝓸𝙫𝓮𝒍.𝒄𝒐𝓶

"Boom"

The new Thunder Bull, nearly ten yards tall at the shoulder, stood like a small mountain before Chen Jiuge.

"So big, such a powerful aura!"

The Thunder Bull, initially at the warrior level, directly leaped to the Silver Blade level, and even among the Silver Blade level, it was not weak.

"Hmm? The bloodline hasn't changed at all, still channeling thunderbolts?"

Chen Jiuge sensed the feedback, a trace of confusion in his eyes, how could there be no change?

Due to the nurturing, the new Thunder Bull harbored not much malice towards Chen Jiuge, feeling somewhat close instead.

"Show me your ability!"

"Moo"

After a single moo, a heavy, foreboding tribulation cloud appeared in the sky.

"The power of this Heavenly Tribulation has already reached the limits of the Silver Blade level?"

"If every Thunder Bull evolves with such abilities, the cumulative summoned Heavenly Tribulation would be immensely powerful!"

With this thought, Chen Jiuge felt a bit restless: "No, I need to speed up the nurturing of Thunder Bulls!"

"Even if these new Thunder Bulls can't collectively summon a Heavenly Tribulation, they can still be used to cultivate some Thunder Attribute spiritual materials!"

A Heavenly Tribulation is a treasure. The spiritual materials it strikes tend to undergo a certain transformation, eventually becoming precious Thunder Attribute spiritual materials, like the well-known Thunderstruck Wood.

"As expected, I'm best suited for nurturing spiritual beasts!"

However, despite saying this, it was impossible for Chen Jiuge to abandon his current forces and focus solely on nurturing spiritual beasts.

A Hundred Arts Cultivator without self-defense cannot be anything but a tool in other cultivators' hands for generating resources.

The nurturing of other Thunder Bulls was also smooth, with the final result exceeding Chen Jiuge's expectations.

These newly strengthened Thunder Bulls could not only work together to release large-scale Heavenly Tribulations but compared to before evolution, though they still couldn't fully control the Heavenly Tribulation, they could manage some simple operations.

For instance, directing a small bolt of lightning at a specified spirit plant, although not achieving very precise operations, the success rate was above fifty percent, which was already sufficient.

Yet, this wasn't the most surprising thing for Chen Jiuge. The biggest change was that when the Thunder Bulls collectively summoned a Heavenly Tribulation, the scattered thunderbolts refined one of the Thunder Bulls!

Although short tests didn't show immediate effects, over time, this Thunder Bull would exhibit phenomena, which Chen Jiuge wasn't worried about, as despite being nurtured, the Thunder Bull's strength remained at the Silver Blade level and wasn't of immediate use.

"The nurturing of two fierce beasts has taken me half a month, this efficiency is still too low and must be increased!"

For an ordinary Beast Master, Chen Jiuge's speed would be considered terrifying, but he was not satisfied. Even without external pressure, this speed was too slow.

The types of fierce beasts in the Hundred Beasts Plain exceed hundreds, and currently, the Thunder Bull and Moon Gazing Rabbit are not particularly populous fierce beasts. The pace of future nurturing will inevitably slow down.
