"Qingqing, those blank papers I gave you, has there been any progress in your research?"

Ouyang asked directly, but Su Qingqing shook his head helplessly.

"I'm sorry, Ouyang, I've tried all kinds of ways to get rid of those blank papers, but they still can't help, whether it's immersion in water, iodine, or some other chemicals, they can't make the fonts appear on these white papers, I have some suspicions that these are just ordinary white papers."

Su Qingqing's words made Ouyang a little helpless.

The investigation of the optical equation obtained from the CIA has reached a bottleneck, and if Su Qingqing's investigation still does not break through, then I am afraid that it will not be possible to find any clues about Teacher Meng Jiang at all.

Su Qingqing comforted: "Ouyang, although the clue is broken, as long as you don't lose hope in your heart, then it is possible to overturn the case for Teacher Meng Jiang." ”

Ouyang looked at Su Qingqing......

"Qingqing, do you also believe that Teacher Meng Jiang is innocent?"

Su Qingqing smiled: "Of course, I was also a student of Yuzhou University, Teacher Meng has a good reputation in the school, and his style is quite decent, how could he do something that betrays the interests of the Huaxia Federation?" ”

"Thank you."

Ouyang said gratefully, this period of investigation made Ouyang himself a little shaken, thanks to Su Qingqing's words, he rekindled his confidence.

The two were discussing what to do next, but they didn't want to suddenly have an abnormal situation around the villa!

"Someone!"

Ouyang exclaimed, and came out of the house and came to the garden of the villa.

Four masked men are waiting here, exactly like the masked men I met a few days ago!

But last time, he disguised himself into the appearance of Teacher Meng Jiang, and it was reasonable to be chased down, but this time, he recovered his original appearance, and these masked people still came here, which showed that they were coming for themselves.

And so it was! Your goal was not Teacher Meng Jiang from the beginning, but me! ”

Ouyang smiled bitterly, since the other party had already killed in front of him, how could he have a reason to retreat?

So Ouyang Shen calmed down and began to calculate!

The strength of the other party is extremely strong, and Ouyang knows it, so this time, Ouyang didn't dare to slack off, and went straight to the fullest!

"Boom!"

With a loud bang, four tornadoes headed straight for the four men in black.

Ouyang's calculation speed has reached 72 times per second, which is almost close to the level of a bachelor, and with the power of absorbing [slices], the power of the four tornadoes is naturally extraordinary.

However, before the four tornadoes could hit the four masked men, one of the masked men stretched out his hand and waved, and the fierce tornado instantly turned invisible!

Ouyang was taken aback, just like the last time he fought with the four masked men, his tornado didn't have any effect at all, and Ouyang didn't even know what equation the other party was using......

Surprised, another masked man pinched a stone in his hand, and the stone turned into powder in an instant, and came towards Ouyang's eyes!

"It's quicklime!"

Ouyang realized the danger and hurriedly stepped back, avoiding the edge.

The attacks of these four masked men were so strange that Ouyang was unpredictable, and he couldn't fight back at all!

And the four masked men were obviously experienced masters, seeing that Ouyang was hesitant, they naturally would not show mercy to their subordinates, so they attacked Ouyang in unison!

In the midst of the crisis, a bell-like voice suddenly sounded behind Ouyang-

"Coordinates! Lock! Curved surface! ”

Subsequently, the attack trajectories of the four masked men all deviated, heading towards another angle, and Ouyang was also taken to the other side of the villa garden by Su Qingqing behind him.

"Thank you, Qingqing!"

Ouyang said softly, if it weren't for Su Qingqing's move, he was afraid that he would suffer a heavy blow.

Su Qingqing looked serious, and said: "Ouyang, these four people are all masters, at least at the master's level, now you fight against them, not only can't beat them, but you don't even know what kind of equation the other party uses!" ”

Although in front of Ouyang, Su Qingqing had a gentle attitude, but in terms of combat experience, Su Qingqing was much richer than Ouyang.

Ouyang's understanding of the use of many equations in the world comes from the library of the Shaw Building, but Yuzhou University is an academic place after all, and even the collection of books in the Shaw Building is quite limited.

But Su Qingqing is different, she is a descendant of the Su family, and the Su family was the main force in the war at the beginning of the establishment of the federation, and took the lead!

Therefore, the use of the equations recorded in the Su family's collection is far better than the library of the Shaw Building of Yuzhou University.

"Ouyang, the masked man who neutralized your spiral equation just now uses the energy conservation equation, he absorbs the energy from the tornado, and releases it in another way, if you hit it by mistake, you can't hurt him at all! As for the other person, it's even trickier, he uses chemical equations, but he doesn't know how many chemical equations he uses, so you can't be touched by him! ”

Su Qingqing admonished, and Ouyang's expression became more and more solemn.

Ouyang recalled the last time he had fought four masked men......

Their tornado is completely ineffective, and then they were hit by unknown energy, it turned out to be the energy conservation equation △E increase = △E decrease, this is a three-star equation, it is said that the use of energy conservation equation can neutralize most of the equation attacks, and in the other way, return the other body!

The chemical equation used by the other masked man, of course, includes "CaCO3=CaO+CO2", which can turn the stones thrown by the bull and bear into powder, and can attack himself with quicklime!

No matter how you look at it, these masked people in front of you are quite tricky!

Su Qingqing said again: "Ouyang, these people are very powerful, I am afraid that the two of us will join forces, and they are not their opponents, the best way is to flee." ”

Ouyang shook his head: "If a scholar wants to grow, he must fight enemies who are much stronger than himself!" So, I'm not going to run away! Only in this way can you know how big the gap is between yourself and the real master! ”

“……”

Su Qingqing looked helpless, she didn't expect Ouyang to be so stubborn.

At the moment of life and death, what he thinks about is whether his strength can be improved......

Su Qingqing sighed and said, "Ouyang, there is really you, judging from the situation of these masked people attacking you just now, they don't seem to have any intention of showing mercy to their subordinates, you have a hard fight with them, I'm afraid that you won't be able to get good fruits to eat!" But if you want to give up your life, then I'll be with you to the end! ”

As he spoke, Su Qingqing was also ready to fight.
