Upon entering this secret realm, Qin Feng felt a powerful force instantly envelop him.
This was not the tangible strength of a monster, but an invisible probe.
From that moment, Qin Feng knew that the monster within this cave was beyond his capabilities. It had not revealed itself, but merely through its immense power and sensory abilities, it had already made Qin Feng feel immense pressure. If he were to proceed further and collide head-on with the monster, he would likely suffer greatly.
Even with his perfect defense, it would be a significant drain on his own strength. From the moment he entered this cave, Qin Feng had realized that the monster in this secret realm was not like those found in Level 5 spiritual energy gathering places. If there were a ranking system for these secret realms, the monster here would at least belong to a Level 7 spiritual energy gathering place.
Qin Feng understood that the monster here was at least two levels stronger than him. Since the monster within this secret realm was not something he could easily handle, Qin Feng's first choice was to leave and continue to the next area with highly concentrated spiritual energy to investigate.
Qin Feng knew very well that if he could eliminate the monster in this high-level spiritual energy gathering place, the mecha he obtained would be even more powerful, and his own strength would become even more terrifying. However, Qin Feng also understood that it was impossible for him to defeat the formidable monster within this cave with his own strength alone. The best choice now was to leave quickly. Lingering here would only bring him unnecessary trouble, and might even put him in danger.
Therefore, Qin Feng turned to leave, only to discover that the entrance to the cave behind him had vanished.
This was a shocking turn of events. Qin Feng distinctly remembered not taking a single step after entering this secret realm. The cave entrance was clearly behind him; why had it disappeared?
Could the cave entrance move?
Qin Feng knew this was absolutely impossible. With his current strength and senses, if there were any strange forces within the cave capable of sealing the entrance, he would absolutely not have missed it. Yet, the current situation presented itself before him, and he could not explain it.
He could only punch forcefully towards the position where the entrance had been, but his fist met extreme hardness. This was not ordinary rock, but a wall made of steel. Qin Feng's full-power punch could not break through it, which spoke volumes about the wall's toughness. However, Qin Feng vaguely recalled that the entrance to the cave was clearly formed by the mountainside, and could never have been made of steel.
If it were made of steel, he would have noticed something before entering the cave.
This strange situation could only mean one thing: the monster in this secret realm was more powerful than he had imagined. The moment he entered the secret realm, it had quickly transformed the area into a steel passage. Even with the entrance completely sealed by that monster, escaping from here had become incredibly difficult.
Qin Feng understood clearly that the steel wall before him was the entrance. If he could shatter this steel layer, he could escape and break free from the secret realm's control. However, his previous punch made him feel that even with all his strength, he could not break through this steel wall. In other words, escaping from here was as difficult as climbing to heaven.
Since he could not escape with his bare hands, Qin Feng drew his peerless sword and unleashed his powerful Sword Control technique, striking forcefully at the steel wall. Countless golden light swords instantly formed, fiercely bombarding the wall.
Immense power surged within the cave. Ordinary steel would have been reduced to dust under such a powerful attack, but the steel in this cave was exceptionally hard, even surpassing any material Qin Feng knew. His Sword Control technique was incredibly powerful, with exceptionally fierce offensive capabilities! Yet, facing this steel wall, it was still helpless.
At the same time, Qin Feng could not commit all his strength to attacking the wall. His greatest strength was still dedicated to constantly guarding against the powerful monster in this secret realm. If he sensed any energy fluctuations around him, he would immediately activate his perfect defense to protect himself. Only by surviving could he see hope. If he focused all his strength on attacking the steel wall, he might be ambushed, which would be a loss outweighing the gain.
Therefore, Qin Feng held back with every attack. He could only unleash ten percent of his power to attack this steel wall, dedicating the remaining ninety percent to guarding against the monster in the secret realm. He could not concentrate all his strength, which made his attacks very fragile and made the steel wall appear utterly unbreakable.
After attacking for a long time, Qin Feng only managed to exhaust himself. The steel wall hadn't even shown a single scratch. Although his Sword Control technique was powerful, he couldn't unleash its full potential, rendering it useless against this steel wall.
As time passed, Qin Feng remained cautiously vigilant, but he sensed no movement from the monster in this secret realm. After sealing the entrance, it seemed to have no intention of attacking him, which Qin Feng found very puzzling. Monsters in secret realms were primarily driven by killing. Since it had sensed his presence, the monster should have attacked him. Why was it making no move?
Were the monsters in secret realms different from those in lower-level areas? Were they no longer primarily driven by killing?
Qin Feng pondered, and felt it was impossible.
The powerful force on this planet had sent them here for continuous evolution and to face life-and-death challenges. The monster in this secret realm existed for this very purpose. It would absolutely not let him go. The reason it hadn't attacked him was likely because it was confident he could not escape from here. The monster was not in a hurry to attack, perhaps intending to play with him like a cat playing with a mouse.
With this thought, Qin Feng became very angry. He gradually increased his attack power, from ten percent to twenty percent of his strength. This greatly enhanced the power of his Sword Control technique, and the wall also began to show some signs of damage under his powerful assault.
The increase in attack power gave Qin Feng hope. However, he still reserved eighty percent of his strength to deal with the powerful monster's attack. Even if he couldn't win, he could wear the opponent down. With the power of perfect defense, he could significantly deplete the monster's strength. As long as the monster's power continued to wane, he would have an opportunity to escape from here.
