With skills that can be upgraded infinitely, if I'm invincible, who is?

Quickly, Xiaoyu completed the purchase, and a bottle of herbal essence appeared in Su Yu's backpack.

With a thought, Su Yu produced a delicate little jade bottle in his hand.

The bottle is transparent and contains a pale green liquid.

Su Yu pulled out the bottle stopper, and a faint, fresh scent of herbs and plants wafted into his nose.

"This tiny bottle costs a million gold coins. Hopefully, it's worth the price," Su Yu muttered.

He took the small jade bottle and came to the Nine Cold Mystic Ice Tree.

A drop of crystal-clear, pale green liquid slid from the bottle's mouth and landed precisely at the base of the Nine Cold Mystic Ice Tree.

hum!

The Nine Cold Ice Tree trembled violently, and the fruit on it, which emitted a faint blue light, began to vibrate intensely.

The faint blue glow on the fruit's surface suddenly intensified, turning into a dazzling ice-blue light.

At the same time, fine cracks began to appear on the crystal-clear trunk of the Nine Cold Ice Tree, and the leaves withered and fell off at a visible speed.

wow~

In no time, the entire Nine Cold Ice Tree withered completely, and the light on the fruit instantly faded.

"It's finally ripe." Su Yu smiled.

A single drop of herbal essence saved him three days of waiting, making the money well worth it.

He walked up to the tree, picked the fruit from it, and began to examine its information.

[Nine-Frost Mystic Ice Fruit (Legendary): Consuming this fruit slightly increases one's life essence and soul power.]

[Note: Consuming a certain number of Nine Cold Mystic Ice Fruits can slightly increase one's affinity with the True Meaning of Ice.]

"Hmm? It actually has the effect of increasing one's compatibility with the true essence of ice?" Su Yu was somewhat surprised.

"Master, just take a look at this hint; its actual effect is extremely weak," Little Fish's voice echoed in Su Yu's mind.

"Alright, after all, it's just a legendary resource, so we can't have too high expectations for it." Su Yu shrugged, indicating his understanding.

After carefully storing the Nine Cold Ice Fruit, Su Yu continued speeding forward.

Using resources that upgrade life level and soul level requires a certain amount of digestion time, and now is clearly not a good time.

Su Yu planned to wait until he returned to the Yuhuang Mansion before using it in a unified manner.

……

About two hours later.

Su Yu realized that there was no way forward; he had reached the end of this ice crevice.

"Let's go up first, and then explore the other side," Su Yu thought to himself.

The bottom of the ice crevasse was shrouded in mist, and due to limited visibility, Su Yu's flight speed was not fast.

If we return directly from the bottom of the crevasse along the same route, it would probably take another two and a half hours to get back to the starting point.

However, if he goes up first, with unrestricted vision, he can confidently increase his movement speed to the limit, which will greatly shorten the travel time.

Swish!

With a flap of his thunderous wings, Su Yu sped toward the sky above the ice crevice.

"I wonder how many Nine-Frost Mystic Ice Fruits I can harvest on the other side of the ice crevice," Su Yu thought with some anticipation.

At one end of the ice crevice, he harvested a total of four Nine Cold Mystic Ice Fruits.

According to Xiaoyu, a Nine-Frost Mystic Ice Fruit can increase his life level by about 0.2 levels and his soul level by about 0.1 levels.

It is quite a rare and precious item.

Although the Nine Cold Ice Fruit cannot be used on people whose life level has reached level 10 or whose soul level has reached level 5.

However, this did not affect Su Yu, since his life level and soul level were not above the limit.

A few minutes later.

Su Yu suddenly flew out of the ice crevice.

He looked around and realized that he had arrived at the edge of the snowy region.

Not far ahead of him was a thick, secret barrier that completely isolated the snowy region from the outside world.

Su Yu didn't linger for long before turning around and speeding toward the other side of the ice crevice.

With the blessing of the true meaning of thunder, his movement speed soared to nearly three times the speed of sound, and his whole body transformed into a bolt of lightning.

About half an hour later.

Su Yu arrived at a familiar spot, the very place where he had first discovered the ice crevice.

Swish!

Su Yu plunged headfirst into the ice crevice, continuing to descend deeper into it.

Ten kilometers, fifty kilometers, one hundred kilometers...

Perhaps Su Yu had already cleared them out, because there were no frost flying snakes blocking their way.

A few minutes later, Su Yu returned to the bottom of the crevice.

This time, he sped off in a different direction.

He would be content if he could harvest four more Nine-Frost Mystic Ice Fruits.

Su Yu swept through the area, discovering more and more Nine Cold Profound Ice Trees.

He also replenished his intake with herbal essences once in between.

Based on Su Yu's experience using herbal essences multiple times, one drop of herbal essence can accelerate the growth of the Nine Cold Mystic Ice Tree by about ten days.

One bottle of herbal essence can accelerate the growth of the Nine Cold Mystic Ice Tree by about three years.

The effect is quite good.

About three hours later.

Su Yu picked the tenth Nine-Frost Mystic Ice Fruit, leaving only the last three drops of herbal essence in the two bottles.

This means he spent two million gold coins to acquire ten Nine-Frost Mystic Ice Fruits several years ahead of schedule.

Suddenly, Su Yu felt the ground beneath his feet tremble violently.

Rumble!

A muffled, deafening roar sounded in his ears.

He looked down and saw that the originally flat ground was being squeezed and arched at a speed visible to the naked eye.

"Damn it, is this ice crevice going to close up?" Su Yu cursed inwardly.

Without any hesitation, he flapped his wings and sped toward the ice crevice, leaving a trail of blinding lightning in his wake.

150 kilometers, 120 kilometers, 100 kilometers...

The higher Su Yu flew, the thinner the fog became, and the more he could observe.

He discovered that the ice crevice was indeed closing, and the smooth ice walls on both sides were crushing towards him at an extremely fast speed.

Lightning! Lightning!

With a thought, Su Yu used Thunder Flash ten times in succession.

With the blessing of the true meaning of thunder, the teleportation distance of the lightning flash is close to ten kilometers.

In an instant, Su Yu burst out of the ice crevice and flew into the air.

"What's going on?" Su Yu looked at the ice crevice below that was closing, filled with doubt.

"Master, perhaps it was because you picked all the Nine Cold Ice Fruits that you triggered some kind of protective mechanism in the snowy region?" Little Fish guessed.

A short while later, the ice crevice below completely closed.

"Luckily, I have enough tricks up my sleeve, otherwise I would have been in big trouble." Su Yu shook his head helplessly.

Without using lightning, he definitely wouldn't be able to escape at his current movement speed.

"Perhaps this is what they mean by 'fortune favors the bold'." Su Yu looked at the ten Nine-Frost Mystic Ice Fruits in his backpack and a smile appeared on his lips.

Ten Nine-Frost Mystic Ice Fruits can roughly increase his life level by 2 levels and his soul level by 1 level.

This is absolutely a huge gain!
