The Ice Castle had already entered three places, and only the square passage had not been entered, and based on the crowd gathered on all sides, Leo judged that the trapezoidal passage should be the simplest and most practical.

Cultivating war beasts, whether mages or wizards are very enthusiastic, just write the cultivation method in the book, you can get the result of success, this kind of level is not so much a test, not a magical conjecture experiment.

Leo thought as he walked to the square passage, where the vast majority of the people were wizards, and there were only a few mages, and it was also the place with the smallest number of people, even fewer than the dismantling model.

According to the number of people, the easiest should be the trapezoidal passage, followed by the triangular passage and the diamond passage, and the most difficult is this square passage, is it really difficult, so that those mages are reluctant to set foot here. With anticipation, Leo stepped into the square passage.

The world in front of you is like a square passage that is infinitely stretched, and you can't see the end of the passage, you can't see the so-called books.

Leo endured the feeling of disorientation and stepped on the first square in front of him, and a small sound sounded, this time there was no sudden change in the scene, but the square in front of him began to move.

The eyes are full of the same kind of figures, although the speed of movement is not fast, but the illusion produced is enough to dazzle people, the movement does not stop, Leo does not dare to move, he can only wait quietly.

Time passed minute by minute, and after half an hourglass, the moving box suddenly reverted to the same as when he first entered, and just as Leo made a move, the scene in front of him suddenly changed, and he was already outside the castle.

'What's the matter, that's the end?, why isn't there that feeling of knowing what to do so naturally like somewhere else?' Leo's mind was full of question marks, and he stepped into the square passage again, and the scene before him appeared again, the scene he had just experienced.

This time, Leo didn't stare at the changes in front of him, but looked around carefully, and he wanted to see what caused him to fail the graduate school entrance examination just now.

Half an hourglass later, the moving box suddenly stopped, and the scene in front of him suddenly changed, and the situation outside the castle appeared in front of him again.

Half an hourglass!

The time to enter is only half an hourglass, which means that after entering, you must make some kind of choice within half an hourglass, and the method of choice should be hidden in the movement of these boxes.

Leo stepped into the square passage for the third time, and he stepped directly on the first box, his eyes fixed on the square passage in front of him.

‘13579... Singular... Move left, 2468... Even... Moved to the right, 147 up, 258 down, 369 didn't move... Wait a minute.... Leo's eyes rolled around, and he quickly made a mental note of what he observed.

Suddenly, he saw the box representing 1, the second box of the original passage, appear in front of him again, and a suspicion instantly appeared in his heart, Leo knew how to pass this square passage.

When the box appeared in front of him again, Leo stepped forward, and a small 'clang' sounded again, and the moving box in front of him suddenly doubled its speed.

The box representing 2 was instantly out of Leo's sight, and he couldn't be sure after observing it for a long time, so he had to take a lucky step forward and appear outside the castle without any luck.

No wonder there are the least number of people here, this method of testing is too difficult.

Wizards account for the vast majority here, probably because these wizards have transformed their bodies and are better at coping with the changes in the passage than others.

In the no-man's corner, Leo sat on the ice, looking at the ice castle in front of him and falling into deep thought, he was thinking about how to get those books through the test inside.

The simplest trapezoidal passage is undoubtedly the best choice, as long as the disciplines closely related to biology, botany, and materials science reach the master level, I believe that passing through the first few layers is not a problem, but there is a huge trap in this, and the seemingly simple is the most difficult place.

Wizards go from apprentice to level 1, and then to the highest level of ninth, each level has knowledge that matches it, and if you want to cultivate a creature to level 9, the knowledge itself is not so high is simply a fool's dream.

The same is true for the dismantling model, although it is a zero-level witchcraft model, but the higher you go, no one dares to guarantee that there will be no ninth-level witchcraft model, and you don't have the corresponding knowledge, not to mention that it is impossible to disassemble or analyze the types.

The speed of the square channel will double when it goes up the first layer, although I don't know how much the speed of the third layer will increase, but it will definitely not increase less than the second layer, as for what kind of speed the ninth layer will reach, just thinking about it makes people dizzy.

The triangular passage is the highest level that someone has reached so far, and it takes a lot of linguistics to decipher a book, and although I don't know the font of the black book, I can still decipher it with a lot of time.

Some of these four passages obviously require the strength of the ninth level, but why are only people of the first level and below allowed to enter here? There should be details in this that I have not discovered.

Leo, who figured out the key, got up and went straight to the triangular passage, and his figure appeared directly in a square on the second floor, in which he was placed not with the sound of a dwarf hammer but with the sound of an orc.

After an hourglass, Leo appeared outside the castle, and he turned and re-entered the passage, this time not the 'Dwarven Hammer' nor the 'Orc Voice' but the 'Milmoth Language'.

'Random. Leo knew in his mind that the test of the castle was random except for the fixed pattern and square passage.

If you're lucky, with the amount of knowledge that Leo has mastered, I'm afraid you won't encounter the triangle text again when you reach the top of the triangle passage.

'Could it be that the test of this castle is also a test of luck?'

Luck has always been considered by wizards to be the biggest gain, and a good fortune can shorten the cultivation time by dozens of times, just like Leo's good fortune to discover the electric rune.

But is it true that nine steps can be good luck every time?

Wait. In his thoughts, Leo suddenly thought of a stupid way, that is, to use the power of God's space to imprint reality, as long as the types of words stored in the triangle are not innumerable, he can print them all, and he can't reach the top even after studying all the space thoroughly?

Also, those witchcraft models are the same, whether it is level eight or nine, layer by layer, with the huge time difference in God's space, can't they all be disassembled?

And whether it's triangular characters or witchcraft models, or biological cultivation, these are all a kind of knowledge accumulation, and the square channel should also have its purpose, but it's just too deep to hide.

I'm afraid that the real purpose of this ice castle is this, it is very likely that this is specially left by ancient wizards for later generations to learn, and the books above the ninth floor are a kind of motivation and also a reward.
