After Bai Yuyou finished eating, Ye Shuang and she really started to review their homework while drinking dragon fruit milk, but they were not reviewing cultural classes, but elves.

The knowledge of elves is far more than simple as attribute restraint evolution, etc., which involves physical chemistry and even geographical knowledge related to the local distribution of elves, which are all contents of the elves, but because Ye Shuang can learn them very well, the efficiency is very high.

"The power of 150 destruction of the death light and the power of 120 of the sun flame collide with each other, assuming that the special attack index of the grass spirit that releases the sun flame reaches 251, and the special attack index of the fire spirit that releases the destruction of the death light reaches 199, find out how high the explosion power index generated by the collision of the two skills will be."

"Considering the relationship between the general system and the grass system without attribute restraint......"

When Ye Shuang saw this question, he took out the formula and began to calculate, and after a while, he took out the calculated answer and compared it with the answer after the practice question, and immediately frowned.

Wrong.

"The steps and formulas of the calculation should be correct...... Ye Shuang flipped through the formulas he wrote, but he still didn't see anything wrong.

Bai Yuyu saw Ye Shuang's appearance, took out a piece of paper and wrote a few words-[Review the question carefully|ω•')]

"Examination ......" Ye Shuang looked at the question again, and after a few seconds, he suddenly realized: "Forget to consider the bonus of the power of the system, the sun flame will have a one-half power bonus when released by the grass elves, and the fire spirit will not release the destruction of the death light." ”

Ye Shuang recalculated it and finally came up with the correct result.

"It seems that the old problem of not reviewing the questions carefully is going to be changed." Ye Shuang breathed a sigh of relief.

Bai Yuyu on the side nodded slightly.

The two stayed in the dessert shop for an hour and a half, and as soon as they went out to the intersection of the road and were about to go back to school, Ye Shuang heard a commotion next to him.

"Beep!" The police whistle sounded, and a man in the distance rushed towards him with a black cloth bag, followed by three or four men dressed as policemen.

"Get out of here!" The man saw Ye Shuang and Bai Yuyu blocking the alley at the intersection of the alley, and with a hideous face, he took out a bright knife to stab.

"Be careful!" Ye Shuang was about to push Bai Yuyou away, but Bai Yuyou's movements were faster, and his palm slapped Ye Shuang's chest, making him take a few steps back, while Bai Yuyou himself turned sideways to avoid the man's knife.

Smack.

She grabbed the man's wrist and twisted it hard, locking the joint directly and knocking him to the ground.

In less than two seconds, Bai Yuyou subdued the man.

Ye Shuang: ......

It seems that something is wrong with the script?

"Great help!" The policemen then caught up with him, took direct control of the man, and handcuffed him.

"What's going on?" Ye Shuang asked.

"There was a robbery in the store in front, this guy robbed more than a dozen high-quality evolution stones in a row, and it was a pity that the clerk used the elf to talk to him for a while to delay the time and call the police, otherwise we would not have come to the scene as soon as possible." After the policeman finished speaking, another policeman ran next to him:

"Captain, the fleeing Ura on the other side of him was also chased by our Kati dog, so let's take it back to the police station."

"yes, okay." The policeman nodded, and then said to Bai Yuyou, "This classmate, can you go to the police station with us?" ”

Bai Yuyou looked at him, took two steps back and walked behind Ye Shuang to hide.

"I'm sorry, but my friend is a little scared, and you know...... We're just students, and it wouldn't be nice to be targeted by this robber's accomplices. Ye Shuang smiled and said, "Let's just assume that she hasn't been involved in this matter, so let's leave first." ”

Bai Yu nodded softly.

"This ......" The policeman also knew this, and finally saw Bai Yuyu who was silent behind Ye Shuang, so he had to say: "Since this is the case, I won't say anything, thank you for your assistance!" ”

"Okay."

Ye Shuang and Bai Yuyou quickly left the scene.

Back at school, Ye Shuang said to Bai Yuyou on the side: "It really scared me, that guy suddenly rushed over with a knife, how did Bai Yuyou learn your skills?" ”

Bai Yuyou looked at Ye Shuang, and then handed over a piece of paper-

[Afraid of QWQ]

Ye Shuang: ......

You don't look scared at all.

"It's not too early......"

The time had come to six o'clock, and the students of the club activities had also begun to go home, Ye Shuang looked at Bai Yuyou, who had been standing beside him, and asked, "Why don't I send you home?" ”

Hearing Ye Shuang say this, Bai Yuyou shook his head.

"yes, then let's break up here, see you tomorrow." Ye Shuang said with a smile.

Bai Yuyou nodded, and watched Ye Shuang leave the school gate.

After Ye Shuang left, Bai Yuyou turned around and walked towards the school, and finally she returned to the library, pushed open the door and walked in.

"Boom......" There were chaotic sounds from the library, Bai Yuyu ignored them, and walked directly to the deepest part of the library, there was a side door inside, she stretched out her hand to open it, it was dim, and with a snap, she turned on the light.

Under the lights, sofas, tables and chairs, beds, computers, and there is actually a private bedroom in the library!

Bai Yuyou lay on the bed, looking at the ceiling with Gutan-like eyes for a few seconds, she stretched out her hand to hold the quilt, then turned her body over, buried her face in the quilt and rubbed.

……

The sky was already dark, Ye Shuang was walking on the dim path, this was the only way home, but because the street lights were broken, the surroundings were extremely dark.

At this moment, Ye Shuang's mobile phone rang, and he took out his mobile phone, which showed that it was from his sister.

"Brother, remember to buy a bottle of soy sauce when you come back, it's used up at home." Ye Xiaoke's voice came from the other end of the phone.

"Old smoke?" Ye Shuang said: "Is it just a bottle of old soy sauce, do you need to ......?"

At this moment, Ye Shuang, who was on the phone, didn't notice at all that a man behind him walked quietly with a stick, and the next moment......

A black shadow flew out of Ye Shuang's shadow, and he directly stuck out his tongue and wrapped it around the man's wrist!

"What?!" Men are shocked!

Ye Shuang turned his head, and after seeing a man with a stick behind him, he put away his phone: "Isn't tailgating fun?" ”

The man saw Ye Shuang's expression of no surprise, and his other hand quickly went to the Poke Ball on his waist.

"Ghosts, hypnosis."

The ghost's eyes glowed red, and the man fell to the ground with a limp, and the Poké Ball in his hand rolled out.

"Please, someone like me is very vigilant, okay?" Looking at the man who fell to the ground, Ye Shuang rolled his eyes.

After a while, the phone rang again, and Ye Shuang connected and said, "Well, I'm fine." ”

"I'm scared to death, brother, you just suddenly sent a message saying that someone was following you, and asked me to call you in a few minutes......" Ye Xiaoke said with a slight cry: "It's scary." ”

"Sorry to worry you...... I guess it will take a while to go back, and I'm going to take this guy to the police station first. Ye Shuang said.

"Then you pay attention to safety......"

"Okay."
