Lu Yu needed stronger opponents.
Only by battling stronger enemies could he deepen his understanding of the Heaven and Earth Law.
The great path of heaven and earth is vast and boundless. Each person's understanding is only a part of it, and one's lifetime is limited. No individual can completely master it.
By grasping and understanding others' insights into the great path of heaven and earth, it equates to having new understandings of the Heaven and Earth Law and thus enhancing one's own comprehension, bringing oneself closer to the great path.
In simpler terms, it means learning from others' strengths to improve one's own weaknesses.
Use others' strengths to compensate for your own shortcomings.
Solely relying on oneself to understand the Heaven and Earth Law could take an immense amount of time. Moreover, people's comprehension varies. Only by learning extensively can one truly understand the essence of the Heaven and Earth Law.
For now, Lu Yu did not want to leave the duel space for the World Wall Battlefield.
The World Wall Battlefield is too dangerous and not suitable for him to enhance his strength.
In the World Wall Battlefield, he would focus more on survival rather than strengthening his own abilities.
If he could stay in the duel space to improve his strength, why risk his life going to the World Wall Battlefield?
Furthermore, based on his current strength, even if he went to the World Wall Battlefield, he would just be another ordinary Martial Cultivator.
Adding one more or losing one wouldn't make much difference; it's merely dispensable.
Lu Yu came to the edge of the golden canopy sealing the Immortal Demon Lord. This golden canopy was like a solid wall, unlike the other warzones' golden screens, which were just curtains of light.
Thud, thud, thud ~ When his fingers tapped the golden canopy, there was even an echo.
Lu Yu placed his right hand on the golden canopy, concentrating on sensing the surrounding power of space-time.
In his perception, the battlefield where the Immortal Demon Lord resided had space-time swirling like a huge vortex, constantly engulfing demons.
No matter how many demons were drawn in, the space within never filled up.
The number of demons faced by just the Immortal Demon Lord could account for five to seven percent of the entire duel space.
This might sound like a small percentage, but it's an exaggerated figure.
There are thousands of warzones within the duel space, and thus, the warzone with the Immortal Demon Lord has gathered an amount equivalent to fifty to seventy warzones of demons.
The proportion of high-level demons is even higher, possibly reaching ten to twenty percent.
As for Martial Cultivator demons, it's virtually one hundred percent.
Since the Immortal Demon Lord entered the duel space, no other warzones have seen Martial Cultivator demons. All Martial Cultivator demons were sent to the Immortal Demon Lord's warzone.
Lu Yu was searching for opponents, specifically Martial Cultivator demons that had just recently entered the rank.
Of course, he wouldn't be arrogant enough to enter the battlefield of the Immortal Demon Lord and vie for Martial Cultivator demons.
Not to mention whether he possessed the power to deal with Martial Cultivator demons, just the presence of the Immortal Demon Lord standing by would make it impossible for Lu Yu to wholeheartedly fight the Martial Cultivator demons.
His strength was already inferior to the Martial Cultivator demons; in such a situation, being distracted by external factors, Lu Yu's chances of falling were great.
He had his own plans.
Soon, Lu Yu sensed a "big fish" appearing within this "space-time vortex".
The power of space-time within Lu Yu formed a great net, capturing the "big fish" and pulling it away from the vortex.
The "big fish" sensed the disturbance in the surrounding space-time and wanted to resist, but unable to control space-time power itself, it could only succumb to the changes around it helplessly.
It could break this space-time, but that would mean giving up the duel space.
The very goal of a Martial Cultivator demon was to enter the duel space, breach the human defense line, and invade the Divine Martial World. Naturally, it wouldn't break free from the "net".
Even if the entry point differed, it would still end up within its destination in the duel space.
With a thought, Lu Yu vanished from his original spot and appeared in a void space.
Not far from him stood a Martial Cultivator demon.
The moment Lu Yu entered this space, the Martial Cultivator demon noticed his figure and was puzzled to see that the one who had dragged it here was just a Spiritual Realm Martial Cultivator.
However, it didn't hesitate much and instantly displayed its true form, a ten-thousand-feet-high figure appearing in the void.
Lu Yu looked up and saw only a mass of darkness press down like the sky.
That was the hand of the demon's true form, a ten-thousand-feet-high figure that slapped towards Lu Yu as if swatting a fly.
It wasn't even swatting a fly; Lu Yu compared to the size of the true form was at most like a mite.
So tiny he could be ignored.
But the force exerted on Lu Yu wouldn't diminish due to his small stature.
The full strength of the slap was concentrated and exerted on Lu Yu.
Perfect control of power is fundamental for high-level Martial Cultivators, and it's equally true for demons.
Forget mites, even a tardigrade could be smashed with a single slap.
Lu Yu could achieve this too; he could punch and shatter all the cells within his opponent's body.
The ability to deliver force at the cellular level already speaks to the terror of high-level Martial Cultivators.
Facing the attack from the Martial Cultivator demon, Lu Yu remained calm without a trace of panic, unleashing his full strength without reservation.
A silver galaxy flowed in the void, and Lu Yu's figure arose from within it, draping the galaxy over himself, forming a silvery-white battle robe.
