After passing through the guards, Luo Feng tightly grasped the long sword in his hand and stared at the hidden traps scattered around the castle.

These traps may seem ordinary, but they hide deadly traps and killing machines.

He stalked around cautiously, not too far from the huge rock, always on his toes.

Every step is cautious and cautious, for fear of accidentally touching a certain mechanism.

The warrior's instincts told him that the traps that lurked around the castle were not meant to defend against intruders, but to guard something important.

Luo Feng firmly believed that he was getting closer and closer to the answer.

He stepped lightly over a patch of grass and found a dark black hole under the castle walls.

Although he felt a little uneasy, he decided to go in and have a look.

The dark passage is full of decay and coldness, and there is an eerie aura in the deep darkness.

Through the dim light, Luo Feng found that the passage was as intricate as a labyrinth.

He walked in slowly, carefully observing the walls and domes around him with each step.

As he progressed, each mechanism seemed to become more complex and dangerous.

Luo Feng realized that in order to avoid the invasion of these mechanisms, he needed to understand them.

He paused, intently observing a mechanism.

This trap is located around the corner of the passage.

It appears to be an ordinary stone wall, but upon closer inspection, a raised button is hidden inside.

Luo Feng whispered softly, "I don't know what this button will trigger, but if I want to enter the castle, I have to find the answer." ”

He held out his finger and carefully touched the button.

Immediately, a bright light suddenly flashed from beside the stone wall.

In the light, Luo Feng saw an inscription carved into the wall.

"Only the wise can enter the castle."

Luo Feng thought silently.

His body trembled slightly, and he took a deep breath.

The inscription in front of him meant that he needed to solve more puzzles hidden around the castle in order to enter the castle. Luo Feng closed his eyebrows tightly and fell into deep thought.

He carefully observed the arrangement of the black and white plots, trying to find the right path.

"Black and white, what should I do?"

Luo Feng muttered to himself, and he lightly touched one of the white pieces with his fingers.

However, as his footsteps stepped over the area, a strong light suddenly shone brightly.

Everything happened so suddenly, Luo Feng only had time to catch a glimpse of the huge rock that suddenly appeared in front of him and was pushed forward.

Luo Feng hurriedly jumped away to avoid the incoming rock fragments, and immediately retreated to his original position.

He knew that this mechanism was meant to protect the passage to the truth of the castle.

"It doesn't seem like you can just step on a white block to get through."

Luo Feng clenched his fists and looked determined, "I have to find a more accurate method." ”

He revisited the black-and-white patterns on the ground and began to analyze the patterns that existed between them.

"There are three white blocks between every two black blocks."

Luo Feng raised his head and pondered, "Could it be that I have to step on three white blocks before crossing the black block?" ”

He took a tentative step and stepped on a white block.

Then he took a second step, a third step......

Make sure you step on the right white block every time.

Gradually, Luo Feng went deep into the arrangement of the plots, and it became more and more obvious that the touch under his feet was different.

Every time he stepped into the next normal white block, a breeze would blow in from all around.

As Luo Feng continued to move forward, the black and white plots seemed to become more complicated.

Sometimes there are only two white blocks between the two black blocks, sometimes it is four or five.

"There must be some other pattern in this."

Luo Feng frowned and pondered, "Maybe it's some kind of mathematical formula?" ”

He began to write down the numbers in the black and white plots and tried to find patterns using mathematical operations.

However, in the long and arduous exploration, Luo Feng also continued to fail and start over. Luo Feng's mind was full of formulas and models for calculations.

He was immersed in his own world, and only his fingers kept dancing, showing his undivided attention.

The surrounding time also seemed to become silent, and only Luo Feng's calm and flexible mind was constantly deducing the possible results of each step.

Suddenly, an inspiration flashed through Luo Feng's mind, and he stopped his fingers, a hint of hesitation flashed in his eyes.

"Perhaps...... Is the number of white blocks between each black block incremental? ”

He looked up, his eyes radiating a determined and sharp light.

Re-examining the black-and-white patterns on the ground, he began to try to solve the puzzle with this new idea.

Luo Feng shifted his footsteps, stepping on the correct number of white blocks between each of the two black blocks.

As he traversed each area steadily and accurately, an invisible force seemed to be secretly protecting him.

A breeze rustled the leaves in the distance, as if to encourage Luo Feng to move forward.

Gradually, Luo Feng felt the irrepressible excitement in his body.

He knew that he was getting closer and closer to the truth of the castle.
