Finally, all the halos in front of him were about to completely fade. Xu Yi jumped out and threw himself into the thirteenth halo cave on the left.

As soon as he entered, the halo corridor and the halo cave disappeared together. The next moment, Xu Yi's feet fell on the ground, and was in a cave full of dusty spider webs. There was a shriveled body in the cave, standing in front of the white jade bi, without any vitality. The peach forest outside the cave entrance was dense, the sun was just right, and the peach blossoms were in full bloom.

Xu Yi waved his hand and all the spider webs and dust dissipated, and the entire cave was spotless.

He respectfully worshiped the shriveled body with thick hair and no vitality, and then stood up.

"Why did you choose this ghost place? Among all the caves, this cave has the least mystery. Look at this wall, except for a box, what else is there..."

Huang Mei couldn't help but complain.

Xu Yi said, "The place where you realize the truth is beyond the understanding of ordinary people. You should rest quietly for a while." As he said that, he closed the starry sky ring and isolated the wild charm.

There is naturally a reason why he chose this cave.

The ultimate reason is that he recognized this box and called it "Thirty-Six Questions and Mysterious Sides".

He once saw it in an ancient classic. The box seems ordinary, but in fact it is composed of thirty-six lines. The length value of each line represents the guess answer to a question.

The answer is given, but the guess cannot be proved.

Therefore, the most important thing about this "Thirty-Six Questions" is to prove these conjectures.

Xu Yi paid attention to this puzzle at that time, but he was unable to solve it for a long time, so he stopped working on it. Seeing each other again this time, there was a taste of causality and effect.

Of course, the bigger reason lies in Xu Yi’s doubts and restlessness.

After Xu Yi broke into the ghost fairyland, he found that the mathematical principles he had mastered were difficult to use in magical powers, and spiritual creation became everything.

Xu Yi also tried how to apply the principles of mathematics to spiritual powers, but there was no way to do so.

However, he understood the truth that the way of mathematics is close to the great way, and he had heard more than once, especially he had heard it from the mouth of Chen, who turned into a three-legged golden crow.

The powerful power of the Three-legged Golden Crow, who can say this sentence, is enough to prove that what is wrong is not the ultimate principle of mathematics, but his lack of practice and insufficient knowledge.

Now it is rare to see this cave in the Sutra. Some people study thirty-six questions about the mystery, but it is impossible to sit on the spot without causing his throbbing.

There are forty-nine caves, and there are mathematical puzzles in this cave. Isn’t it God’s will?

Even if he had nothing in this cave, Xu Yi would never regret it.

In the halo corridor, it was too long to make Xu Yi feel tired. Kuang Hu was very clear about the puzzle he had to study next, which was extremely exhausting, so he sat cross-legged.

He adjusted his breathing and meditated, rested for a whole night, and then replenished a lot of meat. After he was full of energy, Xu Yi opened the restriction of the Starry Sky Ring, greeted Huang Mei with a word, and stumbled his mind into the white jade bi.

At this time, the reason why Xu Yi knew that consciousness invaded this sea of ​​consciousness, and once he was indulged in it and could not extricate himself, it was extremely dangerous and someone needed to awaken him in a critical moment.

As soon as the thought sank into the jade bi of the sea of ​​consciousness, Xu Yi was surrounded by numbers. Sure enough, the sitting senior left a rich relic in this jade bi of the sea of ​​consciousness.

However, because the time was too long, the ruins that originally originated from the system completely dispersed, and became these chaotic numbers, surrounding Xu Yi.

If others encountered such a situation, they would have been in a hurry. But Xu Yi had extremely difficult mathematical skills and shouted about these thirty-six questions. He had studied these thirty-six questions before. Although he did not explain it, he had also had specific ideas. For two of them, he had broken through to the brink of understanding.

Because of this, when he was surrounded by numbers.

He first started with easy and then hard, and focused on solving the two questions that had almost been solved. As his time deepened, he finally solved the question early the next morning.

The question was solved, and it turned out that there was a mess of numbers. If he caught a thread, a large number would be caught by him, forming the whole process of understanding the question.

Xu Yi stared at the digital combination that had become the entire answering process. After a long time, he finally found clues.

The clue lies in the pen tip. The pen tip of this set of numbers is obviously consistent, while the pen tip of the other numbers is not consistent.

The root cause of this situation is easy to understand, because this is the jade bi of the sea of ​​consciousness, not written on paper, and the pen tip generated in the jade bi of the sea of ​​consciousness is not based on writing habits, but based on the state of mind.

At different times, the mood will change, which is the simplest truth.

After mastering this rule, Xu Yi quickly divided the messy numbers into piles according to the tip of the pen.

I spent a lot of energy to list the numbers of each pile and block into formulas based on the most basic logical relationship.

Of course, this process cannot be completely flawless. Even Xu Yi can list the numbers in each pile of blocks into an equation, less than 30%.

Fortunately, after these 30% are completed, the remaining 70% of the mess combined into a much smaller mess.

However, Xu Yi no longer continued to advance, but tried to use his own abilities to solve the remaining thirty-four questions.

And 30% of this unravelling is his reference object and a prompt board.

Day after day, Xu Yi was performing in the sea of ​​consciousness. His mathematical skills were already amazing. With as many as 30% of the prompts, he quickly solved one problem after another.

As soon as he broke through, he quickly listed the formula and quickly cleaned up the piles of messy numbers.

Finally, on this day, Xu Yi broke through the last problem and successfully cleaned up the numbers of the last pile of blocks.

In the entire sea of ​​consciousness, there are thirty-six combinations of numerical equations clearly listed in layers.

In addition, there is a line of small words: be confused but not aware, be aware but not aware. To solve the middle question, you must look for the body and the outside body, but that's it.

At this point, all the numbers and words in the Jade Bi of the Sea of ​​Consciousness were clearly listed by Xu Yi.

However, Xu Yi fell into unprecedented confusion.

The Thirty-six questions were solved by him on the basis of the wisdom of his ancestors, but he was confused again when these puzzles were solved.

If it is just to solve these puzzles, what is the point?

The puzzles of the same difficulty are endless in the vast ocean of mathematics.
