"Um?"

The amount of mental energy required to upgrade from a lower-level fourth-grade mental power to a middle-level fourth-grade mental power is no less than that required for Lin Yun to upgrade his mental power from level three to level four. However, because Lin Yun's mental power has now reached the lower-level fourth-grade, he can absorb and integrate external mental energy much faster.

In just half an hour, Lin Yun's mental strength had increased to the middle level of the fourth level. But at this moment, Lin Yun discovered something that made his heart stir.

"The Innate Realm allows one to communicate with the spiritual energy of heaven and earth, enabling the external spiritual energy to harmonize with the internal energy within the body. It turns out that spiritual power plays a significant role in this. Just now, my spiritual power was only at the lower level of the fourth grade, so this wasn't very noticeable. Now that my spiritual power has been raised to the middle level of the fourth grade, this effect is much more pronounced..."

Lin Yun thought to himself.

Because his current martial arts level is not high, and the level of his internal energy is not high, his efficiency in communicating with the spiritual energy of heaven and earth is not high. It's like a place with high salaries and good benefits can attract high-level talents, or a beautiful woman or a handsome man can attract more outstanding partners. However, if you are an ugly woman, short, ugly, and poor, your attractiveness will be greatly reduced.

However, it cannot be denied that some people have such strange tastes. A beautiful flower might be planted on cow dung, and a handsome man might fall for an ugly woman. Similarly, a highly talented person might be stuck working in a place with poor pay and poor benefits.

It's just a matter of probability.

Lin Yun's current situation is similar. Although his spiritual power has reached the level that allows him to communicate with the spiritual energy of heaven and earth, his martial arts realm is not high, so he can only communicate with and absorb a small amount of spiritual energy.

However, he was able to communicate with and absorb some of it. Because of this spiritual energy of heaven and earth, Lin Yun's internal energy quickly boiled up and began to increase rapidly.

"boom--"

A few minutes later, Lin Yun's body trembled. His internal energy broke through a bottleneck and began to enter a new path. At the same time, the quality of this internal energy also began to improve rapidly in the process.

"Late stage of internal strength..."

Lin Yun was speechless.

This is truly a buy-one-get-one-free deal. Previously, when he raised his mental strength to level four, one of his martial arts skills also broke through. Now, when his mental strength has been raised to the middle level of level four, his martial arts realm has also broken through.

So be it...

Lin Yun thought to himself.

During this period, he did not deliberately try to break through to a higher realm, but he also did not deliberately suppress it. He liked to let things take their natural course. Now that he had broken through to the late stage of Dark Force, he would speed up his martial arts training!

Try to help him solidify his martial arts foundation at the Dark Force realm!

whoosh—whoosh—whoosh—

Lin Yun closed his eyes and began to experience the changes brought about by the advancement of his martial arts realm.

Half an hour later, the changes within Lin Yun's body began to weaken. Lin Yun opened his eyes and began practicing a series of martial arts techniques, familiarizing himself with his current strength while simultaneously accelerating the slowed-down rate of improvement.

"With my current strength, I should be able to fight against a peak-level expert in the Transformation Realm, and even most peak-level Transformation Realm experts are no match for me..."

An hour later, Lin Yun's physical improvement came to a complete halt, and he stopped practicing, lost in thought.

It's not just because his martial arts level has improved.

Previously, his mental strength was only at the lower level of level three. In terms of level, this level of mental strength was even inferior to that of a late-stage Transformation Realm expert... Of course, a martial artist's mental strength usually only improves significantly when they reach the Innate Realm. Many Transformation Realm martial artists don't even have level two mental strength, let alone level three.

However, in terms of hierarchy, that's how it is.

Lin Yun's mental strength has improved tremendously.

One can advance to a major realm and then a minor level at once, which is already at the level of a mid-stage Innate Realm expert... This mental power alone has a great suppressive effect on Transformation Realm martial artists.

Therefore, Lin Yun believed that even a peak-level expert in the Transformation Realm was no match for him.

"Lin Yu, suppress your strength to the peak of the Transformation Realm, and let's have a spar."

Thinking this, Lin Yun looked up at Lin Yu and smiled.

"Yes, Master." Lin Yu nodded, obediently suppressing his cultivation level to the peak of the Transformation Realm.

"Bang—bang—bang—"

The two began to fight, with Lin Yun using all his skills.

“Master, your current strength is already comparable to that of a typical peak-stage Transformation Realm martial artist. I lack mental power, so your mental power cannot affect me. If you were to use your mental power to suppress me, a typical peak-stage Transformation Realm martial artist would likely be no match for you…”

A dozen minutes later, the two stopped fighting, and Lin Yu analyzed the situation.

"As expected, a single peak-level martial artist is no match for me." Lin Yun nodded.

"The role of mental power is significant, that's for sure. I feel that just from my fight with Lin Yu, I've gained a lot of insights into those advanced martial arts techniques. If I were to raise my mental power to the upper level four..."

Just then, Lin Yun's heart stirred again.

After several hours, he had become certain that raising his mental strength to a higher level would only benefit his understanding of those martial arts techniques, with no negative side effects.

In other words, if he cultivates his internal energy faster, it could very well cause his foundation to be unstable. However, the Cosmic Trading System sells pills that purify internal energy, and if he takes some, there will be no problem.

As long as he learns more martial arts techniques and imprints these techniques deeply on every molecule of his body, allowing him to gain a deeper understanding of each realm of martial arts, that will be enough.

"Hmm? Someone's here?"

However, at that moment, Lin Yun received a message from the detection equipment inside the Qingyun Building. Lin Yun looked up and said softly.

At the same time, Lin Yu also looked up into the distance.

The other party was moving very fast, and he sensed it.

"So you're Lin Yun, the boss of Qingyun Company? Heh, you really have some leisure time, even having time to sit here and enjoy the breeze. The environment here in India is really too bad. How about we go to the United States together?" A spacecraft stopped a few hundred meters away, and a projection of a blond, blue-eyed middle-aged man appeared not far from Lin Yun, laughing.

"Your Chinese is good, but unfortunately your skills are lacking. If this is all you've got, I'm afraid I'll have to disappoint you," Lin Yun said calmly.

The detection equipment in the Qingyun Building has already determined that the other party only possesses the strength of a Xiantian level expert in the Chinese martial arts world. The other party does not cultivate martial arts but magic; in Earth's terms, the other party belongs to the category of superhumans.

Magic relies on mental power, and the opponent follows the mental magic lineage.

"Really? I'd like to see what kind of strength your Qingyun Company has!" the other party said fluently.

"boom--"

The next moment, a huge fireball appeared out of thin air, extremely hot, as big as a room. At the same time, a wind dragon also appeared out of thin air, roaring and emitting a powerful aura.

A whirlwind carrying a fireball hurtled rapidly toward Lin Yun. The fire was amplified by the wind, and the wind amplified the fire's power.

"So they are two peak level four mages. No wonder you are so confident..." Lin Yun said softly, his eyes narrowing slightly as he looked at the scene.

A level four peak mage is equivalent to a martial artist at the peak of the innate realm. The magic of these two level four peak mages complements each other, and when they attack together, their strength is even greater. Lin Yun estimated that the opponent could already easily contend with a level five early stage mage.

A level 5 early-stage mage is at the same level as a level 1 Golden Core early-stage martial artist. In a one-on-one fight, although he is not as strong as a level 1 Golden Core early-stage martial artist, Lin Tian is not a true Golden Core martial artist, but a robot with the strength of a level 1 Golden Core early-stage martial artist.

Lin Tian's strength is slightly inferior to that of a true early-stage Golden Core martial artist. Coupled with the issue of energy consumption, it's truly uncertain who will win if the fight continues.

The US empire has such a mastermind; no wonder it always overshadows China on the international stage and is so confident.

Lin Yun wasn't surprised that the other party knew he had a robot named Lin Tian by his side. However, if the other party thought that he only had one robot named Lin Tian, ​​then they were mistaken.
