Elf: Become invincible from the moment you draw the Unbreakable Barrier!

Cao Hongying is a direct descendant of the Cao family.

He is also the current gym leader of Weihe Gym.

However, because Weihe City is not a national-level gym, it cannot issue permanent badges. Naturally, no one will come to challenge her as a top-level trainer.

Usually, those who are responsible for receiving challengers are Cao family members from other gym-level areas in the gym.

It can not only increase revenue, but also give them more training.

Therefore, Cao Hongying, who had nothing to do, would always come to Leiming Strait to beg for money.

On the one hand, you can fight against the king-level elves and train the elves. On the other hand, you can also see if there are any good things on these king-level elves.

"These two Babu woodchucks have made some progress."

Cao Hongying said indifferently as she looked at the Roentgen cat, which was slightly at a disadvantage under the siege of two Babu Tubos.

However, even though the Roentgen Cat was at a disadvantage, Cao Hongying still had no intention of letting Magneto take action.

Just watching calmly from the side.

It’s not that she is cruel, but the purpose of her coming here is to train the elves’ independent fighting ability.

Therefore, she doesn't care about the length of the battle, or even the outcome, as long as she can help the Roentgen cat recognize its shortcomings.

However, what she didn't notice was that there was an invisible person watching the battle not far below her.

"Two mid-level Heavenly King-level Babu Tubos can't even defeat a Roentgen cat of the same level together. They are really lame."

Looking at the three elves entangled together, Mu Yu complained in his heart.

Although most wild elves are not as good as domestic elves of the same level, it is really embarrassing to be fought alone against two elves of the same level.

However, these have nothing to do with Mu Yu. After casually glancing at the elves that still require a long battle, Mu Yu continued to compare the position of the golden light spot on the treasure detector.

In addition to Magneto and Xenoblade, there is also a golden light spot not far away.

Looking in the direction indicated, a fairly wide cave came into view. It seemed to be Babu Tubo's residence.

Mu Yu hid his body and soon floated into the cave.

The cave was a little damp, but the inside was very clean and there were basically no fruit debris.

It can be seen that the two Bobcats are quite clean.

Walking into the cave, a simple bed made of large leaves appeared in front of Mu Yu.

Around the bed, various kinds of tree fruits were piled together.

Among them, a gem with a golden lightning symbol was lying quietly next to a pile of fruits.

A high-quality Thunder Stone that is not uncommon.

No wonder those two Babu Tubo were not brought along. After all the effort, all I found was an evolution stone.

Mu Yu sighed in disappointment.

This secret place called Thunder Strait is really poor.

There are not many secret treasures.

Just as Mu Yu was about to leave the cave and continue looking for the place where Electabuzz evolved, a purple halo suddenly lit up on the treasure detector.

Mu Yu looked carefully and found that near the green light representing himself, there was a purple light that had never appeared before. It seemed to be within one kilometer of the cave.

After using the treasure detector for so long, it was the first time that Mu Yu saw a purple light spot.

Out of curiosity, Mu Yu decided to find out.

"Heracross, dig about 500 meters forward in this direction."

The height of the cave is only more than three meters, which is not suitable for Stoker and Swampert to come out, so Muyu plans to let Heracross act as a temporary miner.

It is worth mentioning that Heracross completed the upgrade in the secret realm last week and is now a genuine king-level elf.

Although it is also a Fighting-type Pokémon, the king-level Heracross has not grown much in height. Now it is only 1.8 meters tall, not even as tall as Mu Yu. However, its huge horn has become even thicker, longer and more powerful.

"Hey!!"

A white light appeared on Heracross's long horns, and then the entire elf crashed into the rock wall with a bang like a battering ram.

The rock wall broke apart, making a rumbling sound.

Fortunately, this is deep in the cave, and today is a typical rainy day with occasional lightning and thunder. Babu Tubo and Cao Hongying, who are in a battle situation outside, don't notice this place at all.

Soon, with the brute force of Heracross clearing the way, a 500-meter-long tunnel appeared in front of Mu Yu.

Following the opened tunnel, Mu Yu soon came to an underground space that looked a bit like a cave.

There was only a little gray light in the entire space, and occasionally drops of water would drip from the stalactites, making a crisp dripping sound.

"Is this... a portal to a secret realm?"

Looking at the oval light blue door standing in the middle of the cave, which was exactly the same as the portal to the secret realm, a trace of surprise flashed in Mu Yu's eyes.

Mu Yu, who had experienced many journeys to secret realms, was very familiar with this mysterious elliptical vortex in front of him that emitted a faint halo and looked somewhat beautiful.

This is the special channel connecting the real world and the secret realm - the portal!

"Could it be... a rare collision of secret spaces?"

Mu Yu suddenly remembered the introduction of the high-level thunder-type secret treasure called Thunder Crystal that he opened yesterday.

[...In the extremely rare collision of the secret space, a crystal-like secret treasure was condensed...]

The so-called secret space collision, according to the inference of existing technology, is a low-probability contact event that occurs when two fragmented secret spaces move around the real world.

The result of the reaction is that the two secret realms have a certain degree of intersection.

It is possible that the secret realm will expand and become bigger.

It is also possible that space turbulence will occur directly, causing the secret realm to suffer varying degrees of damage.

It is also possible that unknown phenomena may occur that have not yet been fully counted.

For example, the portal in front of Mu Yu...

All in all, the scientific community has not yet reached a clear conclusion on what exactly will happen in this mysterious realm-like overlapping phenomenon.

Therefore, Mu Yu only had a general understanding of it from some scientific journals.

But then again, why does this portal appear as a purple light spot on the treasure detector?

Mu Yu had taken out the treasure detector before near the secret realm guesthouse, but the portals to the primary, intermediate, and even advanced secret realms were not displayed.

Could it be that this portal corresponds to a secret realm of a higher level?

Or maybe, the portal within the secret realm is considered a treasure trove within this secret realm?

Let’s not talk about the latter for now. If it is the former, then the secret realm that is one level higher than the advanced level, wouldn’t it be the top secret realm with a champion-level master? ?

If the speculation about the collision of secret space that he had read in the journal was true.

Then, the only top secret realm close to the Thunder Strait is probably the Thunder Valley, which has been owned by the Cao family for generations!

After thinking for a moment, Mu Yu still felt that practice makes perfect.

Instead of daydreaming here, why not go in and take a look.

Anyway, the portal is not a one-time use, so it doesn’t matter if you don’t come back.

If so, it is a top-level electric secret realm. I think it should not be difficult to find a place suitable for Electabuzz to evolve.

Who knows, you might even run into an elf with great potential.

As for the champion-level elves?

Even in the top-level secret realm, the champion level is not something that can be found everywhere, not to mention that the area of ​​the top-level secret realm is much larger than that of the high-level secret realm.

It's not easy to encounter a champion-level elf.

Currently, none of the top secret places known in the world has an area less than one million square kilometers.

In other words, each top secret realm is basically no smaller than the total area of ​​the Northeast region.

This is just a small talk.

Some larger top-level secret realms have an area of ​​about three to five million square kilometers, which is equivalent to one-third or even half of the area of ​​the Great Xia Alliance.

This is also the reason why some small country alliances, despite their small land area, are still able to cultivate powerful elves.
