Immortality and cultivation: Heaven rewards diligence, and success is inevitable.

"Since you're relentlessly pursuing me, don't blame me for being ruthless," Jiang Shi thought to himself. Facing such an enemy, even a female cultivator, Jiang Shi would not show mercy.

With that thought, a top-grade magic weapon, the Mountain and Sea Banner, fell into Jiang Shi's hands.

After being infused with magic, the small flag quickly grew larger, becoming a large flag resembling a spear.

Jiang Shi gently swayed, and in an instant, clouds and mist billowed out.

It swept towards him from behind.

Jiang Shi rarely used this superior magical artifact, the Mountain and Sea Banner.

Normally, he would use magic to trap his enemies and then use offensive means to kill them.

This is the first time I've used this top-grade magic weapon, the Mountain and Sea Banner, against an enemy.

"How dare he lay a hand on me!" The female cultivator was furious.

In her eyes, the other party was merely a Grand Cultivator in the early stage of Foundation Establishment.

Moreover, he was a Foundation Establishment stage cultivator with three storage bags hanging from his waist.

How did they have the audacity to lay a hand on her?

As the smoke billowed over, flames erupted from the female cultivator's body, colliding with the smoke.

She definitely wouldn't dare let the clouds get close.

By the time she broke through the clouds, Jiang Shi had already vanished without a trace.

"Fine, I'll remember you! Next time we meet, I'll definitely avenge this!" the female cultivator said through gritted teeth.

She now hates Jiang Shi, blaming him for not obediently shielding her from the strange bird behind her.

Sometimes, hatred comes out of nowhere.

Jiang Shi was unaware of this at the time.

Even if he knew, he didn't care, because Jiang Shi had already put this female cultivator on his kill list.

Once Jiang Shi is familiar with this level of the secret realm, he will take immediate action to eliminate the female cultivator if he encounters her again!

To avoid trouble, Jiang Shi has now burrowed underground.

Since there are fire giants on the ground and crimson birds in the sky.

There's also the possibility of being ambushed by a stranger at the Foundation Establishment stage at any time, so it's better to just sneak underground.

Although Jiang Shi no longer possesses the superior-grade magic weapon, the Qingyue Spear, he has now fully mastered the true meaning of the mutual generation and restraint of the five elements.

Even without the superior magic weapon, the Qingyue Spear, he could still manipulate the soil and use earth-based magic to travel.

In this fire-elemental secret realm, using earth-elemental magic is actually much easier.

Because Jiang Shi possesses the true meaning of "Fire generates Earth," the dense fire-type spiritual energy in the secret realm can be transformed into earth-type spiritual energy by Jiang Shi.

Using earth-based magic is actually easier and more efficient.

Similarly, earth-based spells are easy to use, while wood-based and water-based spells are difficult to use.

There was not a trace of wood or water elemental energy in the world.

If a Foundation Establishment cultivator with a wood-type spiritual root were to enter this secret realm, they would likely be severely injured by these flames on the spot, and suffer a qi deviation.

Wood-type elements will ignite flames, causing the fire to burn even more severely.

And so Jiang Shi moved forward, lurking in the soil.

They kept an eye on the ground to prevent any danger or treasure from being found.

Just then, Jiang Shi suddenly noticed a strange movement coming from the ground.

Jiang Shi immediately changed direction and rushed towards the source of the disturbance.

On the ground, five Foundation Establishment stage cultivators were besieging a fire giant.

Of these five Foundation Establishment stage cultivators, three were in the late Foundation Establishment stage and two were in the middle Foundation Establishment stage.

The five of them came from the same sect, and they worked together very well.

When fire spells are cast together, their combined power is far greater than when they are cast individually.

"Senior brother, this fire giant's body is made of rock, which makes it extremely resistant to fire. It's very difficult to destroy it using fire magic," a Foundation Establishment stage cultivator said.

This fire giant was born in this fire-elemental secret realm.

They are born with extremely strong fire resistance, and most of those who enter this fire-type secret realm are great cultivators with fire spirit roots.

They were skilled in fire magic, so naturally they had no means of attacking this fire giant.

"You're right, but although our attacks only caused minor damage to the fire giant, it's slow-moving and lacks intelligence. We can wear it down eventually, like water dripping on a stone," the senior brother said.

"This fire giant has a fire spirit diamond inside its body, which is a second-grade high-level spiritual item, and it is the easiest second-grade spiritual item to obtain."

After the senior student finished speaking, his junior brothers and sisters immediately became excited.

The Fire Spirit Diamond is a second-grade superior spiritual object, containing extremely pure fire-type spiritual energy.

Whether it's cultivation or crafting magical artifacts, it's all possible.

For these Foundation Establishment stage cultivators with fire elemental roots, that was the best treasure.

Most importantly, this fire-type secret realm is filled with fire giants.

Although these fire giants are all at the late Foundation Establishment stage and possess formidable strength and fire resistance, their slow speed and inability to fly make them relatively easy to deal with.

Some Foundation Establishment stage cultivators who venture into the fire-type secret realm do so because of this Fire Spirit Diamond.

After all, that was a second-grade superior spiritual item, a rare treasure in the Foundation Establishment stage.

Underground, Jiang Shi's eyes lit up when he heard about the three elements: Fire, Spirit, and Drill.

This fire-type spiritual object is exactly what he needs most.

I have already mastered four of the Five Elements Refining Techniques, and the remaining one, the Heart Refining Technique, is the most difficult to master.

Having a second-grade superior fire-type spiritual object, the pure fire-type spiritual energy it provides will definitely be helpful to him.

Thus, Jiang Shi had a target in this fire-elemental secret realm.

He wanted to collect some Fire Spirit Diamonds before going to find the Marrow Cleansing Spring.

Use the Cleansing Spring to gently absorb the fire-elemental spiritual energy of the Fire Spirit Drill.

Then, he strengthened the heart and created a low-grade fire-based body-refining technique.

Jiang Shi thought about it and decided that it was feasible.

The main goal now is to obtain the Fire Spirit Diamond.

However, how to deal with this fire giant still requires careful consideration.

There were five Foundation Establishment stage cultivators right in front of him, who could be used as guinea pigs for Jiang Shi's experiments.

Therefore, Jiang Shi did not directly kill and seize the treasure. He wanted to see first how the fire giant was defeated and whether it had any weaknesses.

On the ground, five Foundation Establishment stage cultivators surrounded the fire giant, cooperating with each other to form an array and besiege the fire giant.

This lone fire giant was specially selected by them.

To prevent the fire giants from becoming too numerous and difficult to deal with.

Fire spells do virtually no damage to the fire giant.

However, as it slowly wore down, the fire giant began to break down.

And so, a day passed, and finally, after eight hours, the fire giant collapsed to the ground.

Its chest was pierced, revealing a crimson diamond.
