Following Stark, as if afraid that he would really leave, Isaac grabbed him with one hand and hurriedly said, "Hey, hey, Mr. Stark, I'm sorry. I'm sorry! I said something wrong just now. Let me apologize to you first!

"I really want to buy this C-grade two-handed sword."

Stark continued to walk out of the palace.

Looking at this situation, Isaac finally couldn't hold it in any longer, so he directly said, "How about this, Mr. Stark? You name a price, and I'll definitely buy it. I won't talk back!"

Finally, after these words rang out, Stark's footsteps finally stopped. He turned back to look at Isaac and casually said a number.

"5,000 crystals."

The moment he said that, Isaac was stunned.

But in that moment of hesitation, Stark's voice rang out once again.

"Not enough? Then add another 5,000 crystals."

Isaac was completely dumbfounded. He ignored everything else and said, "Alright, deal! 10,000 crystals then!"

Only after seeing that Isaac had agreed did the corners of Stark's mouth reveal a smile. He turned to look at him and said, "Tell me, how are you going to pay?"

"Crystal wristband. In one go," Isaac gritted his teeth and said.

As he said that, he took out his crystal wristband.

It showed that there were still 120,000 crystals left. This was the wealth that he had accumulated after continuously hunting extraordinary creatures for several days after becoming an extraordinary human.

At this moment, his heart was bleeding again!

However, if this C-rank two-handed sword was placed in the auction house, it would be worth this price.

When he thought about how he would be able to obtain a more powerful weapon soon, Isaac immediately braced himself. He swiped the 120,000 crystals over.

"This additional 20,000 crystals can be considered as my apology to Mr. Stark."

Isaac said to Stark.

He was really afraid that Stark would go back on his word, so he simply paid 20,000 crystals more.

Looking at the 120,000 crystals that he had successfully received, a satisfied smile appeared in Stark's eyes.

120,000 crystals were more than five times more than the 20,000 crystals sold in the system store.

How could he not be satisfied?

Immediately, Stark threw the Snake Shadow Two-handed Sword in his hand to Isaac, and the transaction was successful.

After doing all this, Stark was just about to sell the other Blue Moon Staff when Sandy, who was beside him, could not help but feel a little tempted.

Even though it was only a D-grade weapon, it was still a big temptation for her, who only had an E-grade weapon now.

Sandy walked forward and said, "Mr. Stark, regarding the staff in your hand, can you..."

Since he had an offer, Stark naturally would not refuse.

In any case, it was much more cost-effective than selling it to the system store.

Stark also gave Sandy a price.

In the end, this Blue Moon staff was also sold for 25,000 crystals. Sandy and Lisa worked together to gather enough crystals to buy it.

After the transactions, this trip to the Mayan ruins had come to an end.

Stark watched as John and the others split the three E-class weapons and 4000 crystals and left.

He himself did not leave.

For things like crystals, it was better to use them as soon as possible.

After all, improving one's strength was something that would follow him for the rest of his life.

Therefore, after confirming that John and the others had completely left, Stark opened the system panel. Crystal balance: 250,000.

[Current gale attack level: LV. 4

Thunder level: LV. 4

Oracle level: LV. 4

Starsoul Flash level: Lv. 1]

[Would you like to spend 2000 crystals to strengthen the lightning to LV. 5?]

"Yes."

Stark pressed the confirm button.

[Ding! Skill upgrade successful! You have awakened a new skill: Lightning Strike.]

..

Upgrade!

[Do you wish to use 2,000 crystals to upgrade Gale Attack to LV. 5?]

[Ding! Skill upgrade successful! You have successfully awakened a new skill: Wind Blade Tornado.]

..

Upgrade again!

[Do you wish to use 2,000 crystals to upgrade Oracle to LV. 5?]

[Ding, skill enhancement successful! Every creature you kill next will provide you with an additional 70 EXP.]

..

[Would you like to consume 3,000 crystals to upgrade Oracle...]

..

Stark did not hold back as he poured more crystals into the skill panel to upgrade the skill.

A few minutes later.

After a series of crazy enhancements.

Stark strengthened his Thunder, Gale Attack, and Oracle abilities to the max level of level 10!

At the same time, he also awakened all kinds of powerful new skills because of the enhancement of his abilities!

After a round of screening and selection.

Stark finally sorted out all these main skills.

[Lightning ability: Lightning Chain, Lightning Ball Explosion, Lightning Strike, Magneto Storm]

[Gale Attack ability: Tornado Fury, Dragon Roar, Wind Blade Tornado, Storm Surge]

Among them, Magneto Storm was a skill that he awakened when he strengthened his lightning ability to the maximum level.

After using it, it was said that he could summon a lightning magnetic field. At that time, all the creatures in it would be trapped inside, and at the same time, they would be destroyed by continuous lightning strikes.

As for Storm Surge, it was also a skill that had been strengthened to the max.

The description of the skill was also extremely simple.

A buff skill, using the storm ability to strengthen oneself, allowing oneself to attack five times consecutively in an instant!

Perhaps it was just the description on the interface, so he could not feel the specific power of this skill.

However, Stark quickly understood one point.

This skill was said to enable to attack five times consecutively in an instant, and it could also buff other skills at the same time.

In other words, after using Storm Surge, he could even cast his strongest attack, Storm Lightning Slash, five times consecutively.

The previous Storm Lightning Slash had successfully killed the Amethyst King Snake. If it was cast five times in an instant, the consequences would be terrifying.

After all the skills were strengthened, Stark took out the amethyst crystal he had obtained from the Amethyst King Snake.

"System, activate class change!"

Stark's voice sounded. As the amethyst crystal shattered, the essence of the spiritual energy within it surged into his body. At the same time, 20,000 crystals were consumed.

His entire aura was also rapidly increasing.

Very soon.

A system notification sounded in stark's ear.

[Ding! Congratulations to the host for successfully completing the class advancement. Class advancement to SSS class: Pope.]

"Class advancement successful."

After completing the class advancement, Stark immediately looked towards his new class.
