Li Qingyu was stunned!

He used to be an ordinary student in a third rate University. Just because he fell into the sewer, he met a big snake, drank the blood of the snake, swallowed a round, egg yolk sized thing, and then suddenly had a power. From then on, he embarked on a different life path!

This is Li Qingyu's ultimate secret, no one knows, even his parents, his lover, his brother, he did not tell them!

Of course, he didn't tell them, not because he didn't trust them, but because he always felt that it was too weird, and it seemed that it wasn't over yet. There should be a follow-up. As for whether the follow-up was good or bad, it's not sure!

So, if you tell them the truth, it is likely to bring disaster to them!

So the question is - how did Niu Dahuang know about it? It's not a pulse diagnosis, is it?

Li Qingyu's head turned a little, and immediately realized that it was possible that the follow-up of that matter had come! Niurhubarb probably knows the origin of the snake!

"I don't like grass! Isn't that the man who raised the snake? If so, he knows that I killed his snake, will he slap me to death immediately? Shall I tell him the truth? " Li Qingyu hesitated.

But he immediately denied this idea, if the snake is really raised by rhubarb, then rhubarb guessed that the snake died in his own hands, should hate himself! But now Niu Dahuang is more and more respectful to himself!

Li Qingyu can feel that Niu Dahuang's respect for himself is from the heart, not a disguise!

"Damn, it's a blessing, not a disaster. It's a disaster. I don't think rhubarb is malicious to me. What's more, he saved my life. If I give it back to him, I'll be killed by the hermit family on Lei Guang island! " Li Qingyu thought a little, then immediately made up his mind!

"Brother Niu, I did meet a big snake and drank its blood. When I drank it, I drank something the size of a longan! To tell you the truth, I used to be an ordinary student in a third rate University. Although I'm not stupid, I'm definitely not the most intelligent person. It was after drinking the snake blood and swallowing the mysterious thing that I suddenly became different, and my life path changed completely. Elder brother Niu, listen to your tone, you seem to know the origin of that big snake? "

After listening to Li Qingyu's words, Niu Dahuang was as excited as a child. He clenched his fist and waved it twice. Then he said, "ha ha, I really know the origin of the snake. I'll tell you later. Now I have to ask you to do me a favor. "

As he spoke, Niu Dahuang stretched out his hand and suddenly got a piece of white jade the size of a smart phone. Li Qingyu was stunned when he saw the jade. He found that the jade in Niu Dahuang's hand was very rare. It was crystal clear, warm and delicate. It was clean and had nothing on it.

Rao Shi has made a special research on jade, but he can't see what kind of jade it is! But he was sure that the jade was very expensive, even more expensive than the rare Imperial Green in the world!

"Brother Li, please drop a drop of blood on this jade! This is very important. I hope you don't refuse! " Niu Dahuang also said that his attitude is more respectful and even intimate than before. He just called you and now he is a brother.

Now that he has admitted about the snake, Li Qingyu will not do it. He thinks that he will do everything according to Niu Dahuang's requirements. Now he can be sure that Niu Dahuang must know the origin of the snake, and he may also know a great mystery!

He took the jade from Niu Dahuang, bit his middle finger, dropped a drop of blood on the jade, and said with a smile: "brother Niu, your jade can't be a super magic weapon. Now let me recognize the Lord?"

"Ha ha, what's the matter? You'll know in a moment." Niu Dahuang's eyes were wide open, looking at the jade in Li Qingyu's hands, as if afraid to miss any details!

Jade has a strong Yin water nature. After a drop of Li Qingyu's blood falls on it, it spreads quickly. In a short time, a drop of blood spreads evenly to the whole jade. The whole jade turns pale red, and even the other side turns the same pale red.

Li Qingyu is a little disappointed. According to his experience in Xianxia's online novels, when the protagonist meets the magic weapon, his blood drops and he recognizes the master, the magic weapon will immediately change into something different, such as a sudden Guanghua sage, a sudden wind, a sudden thunder and lightning, and so on!

But now my blood drops on the jade, except the jade evenly spread more mysterious, there is no other vision!

It seems that I think too much. Although the jade looks very expensive, it may not be a magic weapon at all. Or it's a magic weapon, but it's not predestined with you. Your blood can't activate him.

Li Qingyu can't help but look up a little, secretly glanced at the cow rhubarb next to him, want to see if his face is disappointed!

What made him confused was that Niu Dahuang's face was not confused, but more and more excited!

"Well? Why does he seem more and more excited? Is the change of jade in line with his psychological expectations? But - why on earth is that so special? " Li Qingyu has a secret way in his heart.

Li Qingyu was a little puzzled, but he saw that the jade in his hand had changed again. The front of the jade was like a mobile phone screen, and gradually there were dense handwriting!

These handwriting is very small - small as lice head, dense, connected into a piece, and these small characters like tadpoles in the water, can swim in the jade, human eyes can't catch!

Although the word is small, but many, covered with the whole piece of jade, the whole piece of jade from light red into black!

"Brother Li, you may see the dense small characters on the jade?" Niu Dahuang rubbed his hands and asked eagerly.

Although Li Qingyu's eyes are keen, he still can't catch the trace of these small characters, so he can't recognize what they are written.

So he directly released his divine consciousness, locked all the small characters on the screen, and printed their moving tracks in his mind. This time, he understood what these small characters were writing - it seemed to be a very complicated higher mathematics problem, which was more complicated than Goldbach's conjecture!

Although the expression of the title is ancient, but Li Qingyu can see it clearly!

So Li Qingyu immediately said, "it seems to be an advanced mathematics problem to be able to see these small words clearly."

"Can you solve this problem?" Niu Dahuang asked immediately, his eyes began to shine!

"Should it be?" Li Qingyu said, tone is not very sure, because this topic is really very difficult!

Niurhubarb suddenly slapped, said: "good! Then you can solve the problem quickly, as long as you can solve the problem, there will be a huge surprise waiting for you! "
