The treasure-seeking rat has spirit communication, a little beast comparable to the dragon rabbit as a spiritual beast.

However, the dragon rabbit is a spiritual beast capable of finding heavenly materials and earthly treasures.

While the treasure-seeking rat is skilled at finding various treasures buried underground.

The domains of expertise of these two spiritual beasts are not the same.

...

Nonetheless, both the treasure-seeking rat and the dragon rabbit possess extraordinary abilities.

This little creature, upon being summoned, started chirping excitedly.

It waved its little paws, seemingly conveying something to Huo Yihan.

Huo Yihan took out a spirit fruit and handed it to the treasure-seeking rat.

The little rat grasped the spirit fruit with its tiny paws and immediately began munching on it.

This little guy was asking Huo Yihan for something to eat!

After a short while, the treasure-seeking rat finished the spirit fruit and patted its little belly.

Then it jumped into the pond.

The treasure-seeking rat dove into the pond and vanished in the blink of an eye.

Lin Feng and Huo Yihan waited by the shore.

About 15 minutes later.

The treasure-seeking rat swam back up, dragging an iron box.

It was utterly exhausted.

While in the water, it kept chirping excitedly.

Huo Yihan cast a spell to lift both the treasure-seeking rat and the iron box up.

The treasure-seeking rat chirped proudly, seeking praise.

"You little glutton." Huo Yihan tapped the treasure-seeking rat’s nose with her fingertip, her eyes filled with a doting expression.

She handed another spirit fruit to the treasure-seeking rat.

Once the treasure-seeking rat finished the spirit fruit, Huo Yihan returned it to the beast control bag.

Both Lin Feng and Huo Yihan turned their attention to the iron box.

The iron box was about one and a half meters long, one meter wide, and half a meter high. It was crafted from black mysterious iron.

The box emitted a cold aura.

Lin Feng touched the iron box with his hand, and immediately felt waves of Yin Sha Qi flowing into his body.

He quickly withdrew his hand.

Huo Yihan asked, "Is there something wrong with this iron box?"

Lin Feng slightly furrowed his brows and replied, "The Yin Sha Qi is too strong; I feel this iron box is filled with ominous energy."

Huo Yihan reached out to touch it as well.

Her body immediately trembled as if she were going to be encased in ice.

Clearly, Huo Yihan’s strength was insufficient to withstand the Yin Sha Qi emanating from the iron box.

This Yin Sha Qi was, in fact, extreme cold power.

A cultivator with weak cultivation could likely freeze to death.

Huo Yihan’s face turned pale. She wanted to take away her right hand from the iron box but horrifyingly discovered that her right hand seemed glued to the box, unable to move.

Lin Feng quickly grabbed Huo Yihan’s right hand and moved it away from the iron box.

...

Yet, Huo Yihan’s body continued to shiver, as Yin Sha Qi invaded her body. If it couldn’t be dispelled, Huo Yihan would be severely harmed by the Yin Sha Qi inside her.

This young lady wrapped her arms around Lin Feng, seeking some warmth from him.

Lin Feng dared not hesitate, promptly channeled heavenly fire within and under his control, a surge of heavenly fire power flowed into Huo Yihan’s body.

This surge of heavenly fire power roamed through her body.

Instantly.

All the evil cold Qi.

Was completely cleared away.

Huo Yihan’s pale face regained its color.

"It’s okay now," Lin Feng said with a smile.

Huo Yihan realized she was still holding onto Lin Feng, her delicate face slightly flushed, and she quickly pulled away from him.

Lin Feng chuckled, realizing that even this young lady had moments of shyness.

His gaze then fell upon the mysterious iron box, his brows slightly furrowing.

This iron box is no simple matter, covered densely with various powerful array patterns, which even Lin Feng couldn’t think of a way to break at first glance.

"What do you think is inside this iron box?" Huo Yihan asked.

Lin Feng stroked his chin and said, "That’s hard to say, but with these dense array patterns and the chilling aura emanating from it, whatever inside could very likely be extremely dangerous!"

"What should we do now? Should we open the iron box?" Huo Yihan asked. She was initially eager to open the box, but after merely touching it, she almost lost her life. Now, where would she find the courage to open it?

Lin Feng said, "Since we’ve already retrieved the iron box, there’s no reason not to open it. But you should stand a bit farther away now; I’m worried that opening the box might trigger some terrifying events, and I may not be able to protect you."

At this point, Huo Yihan didn’t throw a tantrum and obediently stepped back more than thirty meters, watching from afar.

Lin Feng squatted beside the iron box, studying the array patterns on it.

"The person who set this array was truly skilled, expertly combining various formations. Such a refined technique shows an astonishing study of arrays. I might be able to break it using the secret techniques recorded in the Nine Volumes of Array Breaking from the Heavenly Master Dao, though I’m unsure of my success."

Lin Feng furrowed his brows thoughtfully, resolving to give it a try.

For the next three hours, Lin Feng constantly attempted to break the great array on the iron box.

Finally.

After numerous attempts.

Lin Feng finally found the correct method to break the great array on the iron box.

Spending another hour, Lin Feng broke the great array on the iron box.

Then Lin Feng began to open the iron box.

As soon as the box was opened slightly.

Suddenly, an overwhelming murderous intent poured out, making Lin Feng feel as if he were plunged into endless purgatory.

At that moment, he even felt his life was going to be stripped away instantly.

The murderous intent inside the iron box was too formidable, Lin Feng had only one thought, which was to seal the box again, or else, truly opening it might unleash terrifying occurrences.

However.

Lin Feng was unwilling to seal the box just like that. Having painstakingly broken the array on it, not seeing what was inside would be a pity.

Lin Feng bit his teeth, he opened the box wide.

"That’s...." Seeing the contents of the iron box, Lin Feng’s face was filled with astonishment and fear.
