Outer Gods invade, stuff them all into your equipment inventory.

"The key is that even with this tenfold increase in strength, it's really not that much..."

For a hero with such extraordinary abilities to try and improve their strength on their own is simply a pipe dream.

Even if some hero families or powerful forces want to invest in them and send people to help them improve their hero level.

"Given their condition, which is essentially like that of blind people, even with help, becoming a C-rank hero is already their limit."

Even if a C-rank hero unleashes ten times their strength, they are still no match for a B-rank hero.

The time, effort, and resources required to train them into C-rank heroes have already exceeded the cost of training a B-rank hero.

"Spending more resources to cultivate only a substandard product, or even a disposable one, is a pure curse."

........................

"Heroes do not provide categorized descriptions of their special abilities."

This is common sense.

At least, no one below S-rank hero can do this.

Of course, the world is big enough that there will always be people who think they are different from others.

"For example, that hero who sold me the notebook before..."

Sean still remembers the apprehension and unease in the eyes of that E-rank hero when he made the deal with him.

"He probably wasn't sure if I would accept that notebook."

This so-called earth-walking technique is very likely a written summary of his own hero's special ability.

Everyone knows that this kind of notebook is just trash to other people.

"Although it contains a lot of writing, it's all utter nonsense..."

"I don't understand what he's talking about either."

"But it doesn't matter. As long as the ability name 'Earth Walking' is written in the notebook and an explanation is provided, that's enough."

Sean didn't waste any time and paid 8 Dimensional Gold Coins directly.

Looking back now, the relieved expression on the other person's face probably meant that they thought Sean was some sucker with a collecting quirk.

"He probably made a small profit, but I'm sure I didn't lose out."

Eight dimensional coins for a decent hero ability—Sean is making a killing no matter how you look at it.

With an equipment slot at his disposal, these kinds of notes are a treasure trove that he can keep exploring.

While others possess only one type of superpower, Sean can have countless superpowers.

"That's the difference."

A huge gap.

"I don't know when I'll be able to get my hands on these kinds of notes again. Maybe I could hire a hero to write some similar notes."

Sean seemed to be deep in thought.

"Unfortunately, that seller was only an E-rank hero, and he hadn't developed his abilities enough..."

Due to the extent to which the opponent's abilities have been developed, Sean's use of Earthwalking is severely limited.

"First of all, when traveling on land, you can only move stealthily in a fixed direction."

Once a direction is found, it is impossible to change direction during the stealth process unless the underground journey ends.

Like an armor-piercing projectile with a pre-set trajectory, it can only "drill" down along the initially locked straight line.

"The second drawback is that unless you run out of energy during the casting of the ability, you can't actively end the Earthwalking Technique."

Unfortunately, once the caster's stamina is exhausted, the Earthwalking spell will end abruptly, leaving the caster stuck in the ground at the point of stopping.

If that place happens to be deep underground, the consequences would be unimaginable.

When that seller was demonstrating his skills, he almost got buried underground and wouldn't have been able to get out if Sean hadn't helped.

Sean still remembers the pale, sullen face he saw when he dug the other person out.

This is also the most dangerous aspect of using the Earthwalking Technique.

To compensate the other party, Sean gave them an extra dimensional coin.

Sean first removed the Elite Fallen Body, freeing up an equipment slot.

Compared to the body of the elite Fallen Demon, the body of the mutated Steel Slime is too heavy.

It's also too big to store easily.

He placed the body of the elite Fallen Demon into his storage equipment and equipped the notebook into his equipment slot.

Having done all this, Sean glanced at the absorption countdown displayed above his laptop—

"Still 72 hours."

As expected, the absorption time was reset.

Prior to this, after acquiring the notebook, Sean had spent over an hour equipping it.

The countdown time had been reduced from the initial 72 hours to about 70 hours.

But when he re-equips the notebook now, the progress bar has returned to the starting point of a full 72 hours.

"As expected, the absorption of memory fragments from the same book in the equipment slot must be continuous and uninterrupted. If you unload it halfway, all your previous efforts will be wasted, and you will have to start the timer again from the beginning."

He had only had this guess before, but now he is completely certain.

With the notes complete, Sean immediately mastered the ability to walk on the ground.

Before embarking on the journey, Sean first took out a bottle of stamina potion and put it in his mouth.

He bought this stamina potion from the Hero Association when he was promoted to E-rank Hero.

Once the Earthwalking spell is finished, he will crush the stamina potion and swallow the liquid inside.

This would replenish his strength, allowing him to crawl out from underground and avoid being trapped to death.

"Next... let me first determine the direction."

Rusty Canyon is located southeast of the Boulder Field, so using a compass to determine your location is a good method.

However, Sean has an even simpler method.

He glanced at the sky above.

"The current time is... approximately 9 a.m.

Sean looked up, squinted, and tried to make out the sun's blurry halo through the perpetual mist over the rocky wilderness.

He stretched out his arm and used the most primitive method, using the projection of his arm to compare directions.

"The southeast direction should be...this place."

He completed the location immediately.

He only needs to find the general location of the rusted canyon; he doesn't need to be too precise.

Unlike the others, he didn't need to find the entrance to the Rusty Canyon.

Using the Earthwalking Technique, as long as he leaves the area of ​​the Boulder Wilderness and ensures that his direction is correct, even if the place where he finally emerges from underground is off from the official entrance of the Rusty Canyon, he can still achieve his goal.

With his ability activated, Sean instantly disappeared into the ground, heading southeast at an extremely high speed.

About ten minutes later, somewhere far from where they had been, the soil on the ground suddenly arched and cracked unnaturally.

A muddy hand suddenly emerged from the crack, followed by another.

With a forceful pull of his hands, he widened the crack, and Sean's upper body emerged with difficulty from the mud.

"Ptooey! Ptooey! Ptooey!"

Sean spat out a mouthful of dirt.

During the Earthwalking Technique, he naturally didn't need to worry about the soil interfering with his body.

However, as the effect of the Earthwalking skill ended, no matter how careful he was, some fine sand and dust still squeezed into his mouth and nose.

Sean didn't dare to delay. He struggled to dig away the surrounding soil and finally broke free from the ground, rolling down on the side of the ground.

He lay on his back, his chest heaving violently, greedily breathing in the air from the ground.

Even though the air in the wilderness wasn't fresh, he still found it delightful.
