A faint smile appeared on Mo Yuqi's face, it seems that Qin Yu is not omnipotent!

"This small box is the work of the first generation of the Ghost Valley Gate Grandmaster, and it was obtained by my grandfather who won the Ghost Valley Gate Master by betting on it.

You're right, the structure in the keyhole is really changing, and even my grandfather couldn't open the box without using violence.

However, if violence is used, the box will explode and destroy its contents.

I'll go home and ask my grandmother for the keys. ”

After Mo Yuqi and Qin Yu left, Wen Bichen was suddenly stunned for a moment, Qi Qi, a stupid girl, why did she forget to take the key? Without the key, Long Jiao would definitely not be able to take it out!

If Wen Bichen knew that Qin Yu actually wanted to try to crack the mystery of the box, she would definitely be shocked and unable to say a word.

......

Qin Yu shook his head gently: "Mr. Mo, don't be so troublesome, although the structure in the keyhole is constantly changing, but it can't help me! As long as I know all the changes, I will open the box smoothly." ”

Mo Yuqi's eyebrows raised, he remembered that his grandfather said that the internal structure of the keyhole of this box is varied, at least there are more than 10,000 changes!

"Mr. Qin, if you can't do it, don't force it, after all, this is the work of the first generation of the Guigu Gate. Mo Yuqi looked at Qin Yu with a little worry.

"Mr. Mo, don't worry, if you can't even open such a small box, where do I still have the face to mess around in the lockpicking world?" Qin Yu looked confident.

"Okay. Mo Yuqi no longer persuaded Qin Yu.

Qin Yu attached his ear to it again, and gently tapped the box, and through the echo, Qin Yu could easily judge the structure of the keyhole.

This time, Qin Yu did not rush to transform the wire, but continued to knock on the box non-stop.

Soon, Qin Yu's eyes lit up, because he heard it, the structure inside the box suddenly changed, and a faint smile appeared on the corner of Qin Yu's mouth, sure enough!

Qin Yu didn't stop, he continued to knock on the small box, and almost ten minutes had passed, and the structure inside the keyhole had changed one hundred and eight times! This showed that every five seconds, the structure inside the keyhole had to change!

Qin Yu's face became ugly, and Qin Yu began to think that one hundred and eight times was a reincarnation, and the change in the keyhole would return to the first time.

But what Qin Yu didn't expect was that the one hundred and ninth change was still a brand new change!

Qin Yu's brain is about to explode, remember that this one hundred and eight changes will consume a lot of his brain cells, but one hundred and eight times is not over, there are still new changes!

"It's not scientific, one hundred and eight is the sum of thirty-six Tiangang and seventy-two earthly evils. Isn't the Tianji Gate a keyhole made according to Tiangang and Earth's Evil? No, it's obviously a keyhole made according to Tiangang and Earth's Evil. Qin Yu scratched his hair a little helplessly.

"Mr. Qin, don't worry, the keyhole is made according to Tiangang and Earthshatter, but it is not addition, but multiplication!" Mo Yuqi remembered the conversation between the master of the Guigu Gate and the old pervert in his mind, and explained.

Multiplication? Qin Yu's brain exploded in an instant! Nima egg! What is seventy-two times thirty-six? I'm not very good at math!

Qin Yu took out his mobile phone, calculated it, and let out an exclamation: "God! It's more than 2,000 changes?

"Wrong, you have to add the five elements, it's more than 10,000 changes!" Mo Yuqi said bitterly.

"One...... More than 10,000 changes?" The corners of Qin Yu's mouth kept twitching, Emma, this bragging is bigger than bragging! Even if he is tired to death, he can't handle these more than 10,000 changes!

"So, I'd better go home and ask my grandmother for the keys. Mo Yuqi smiled bitterly.

"No, there is still a little time, perhaps, I still have a chance, since it is a keyhole made according to the five elements of heaven and earth, then there must be a pattern to follow! I'm trying! If we can't get it before seven o'clock, we'll go back to Mo's house." Qin Yu looked at his watch, it was five forty at this time, and there were nearly three hours before the medicinal herb exchange conference at half past eight.

"Okay, but Mr. Qin, don't be reluctant, my grandfather can't open this box, and it's not a shame that he can't open it. Mo Yuqi kindly comforted.

But Mo Yuqi was not comforted, but this comfort comforted Qin Yu's competitive spirit at once! Qin Yu's little temper, how could he be used to a box?

"Okay, I'm not reluctant. He said so, but Qin Yu secretly made up his mind in his heart, if he didn't open this box today, he wouldn't be a man!

Qin Yu no longer tries to memorize all the changes, because that is unrealistic, more than 10,000 changes, how can he remember them?

Fortunately, in the inheritance of the old pervert, there is the knowledge of the heavens and the earth and the five elements, and all Qin Yu needs is to find out the connection between each change.

Qin Yu was sure and affirmed that there must be a great connection between the two adjacent changes, and regarded the Tiangang and Earth Evil and the Five Elements as three constants, and each change should only change one of the constants!

Qin Yu attached his ear to the box again and tapped the box gently.

Qin Yu tried hard to decompose the graphics in his mind into three kinds of data, Tiangang Earth Demon and Five Elements, not to mention, he really let him do it!

Qin Yu's spirits were greatly lifted! If the Heavenly Gang, Earth and the Five Elements were divided into three constants, it would be much easier to comprehend the changes!

Qin Yu continued to tap on the box, and soon, the keyhole made the next change, and this time, Qin Yu's face showed joy! He was not wrong in his judgment! The two adjacent changes were indeed related! There was only a constant difference between them!

Although his spirits were greatly lifted, Qin Yu was not happy too early, he just determined that the constant that changed, but he did not determine, how did this constant change, is there a law to follow?

Qin Yu continued to knock on the box, time passed minute by minute, I don't know how long it had passed, the box had changed more than twenty times.

Suddenly, Qin Yu's eyes lit up, because of the more than twenty changes before, all of them changed in seventy-two Tiangang!

And this time, there is no change in the seventy-two Tiangang, what has changed is the thirty-six earthly demons!

Qin Yu couldn't hold back his excitement and continued to knock on the box, the next thirty-six changes were all thirty-six earth evils, Qin Yu's eyes lit up, if the next change was the five elements, he would be sure!

Sure enough, the next change is not Tiangang or Disha, but the Five Elements!

Qin Yu let out a sigh of relief, damn, Lao Tzu finally didn't embarrass himself in front of his sister! Fortunately, these changes are all regular! Otherwise, no matter how good he is, he won't be able to remember more than 10,000 changes!

Since there is a pattern to follow, it is simple!

Qin Yu estimated that it would take him about fifteen seconds to process the wire, and in fifteen seconds, the internal structure of the keyhole should be able to change three times!

Now what has changed is gold, according to the order of gold, wood, water, fire, and earth, after three changes is fire! In order to ensure that nothing goes wrong, Qin Yu chose to be conservative, took the earth element as a constant, and began to deduce, successfully deducing the shape of the keyhole!
