"You see, this little black ball is the size of an eyeball, and it appears in this position with the most ordinary and ordinary appearance, and this position is just right to see the whole process of the battle, and it is not easy to be detected, this is definitely not simple!" Hei Yaotian analyzed it carefully, but Chen Zisheng and Li Jianqiu were all correct.

This little black ball appears here, do you want it?

Hei Yaotian looked at the expressions of these two people, and sure enough, he still looked disbelieving.

"You don't believe me?" Hei Yaotian asked coldly.

Chen Zisheng and Li Jianqiu were so frightened that they were anxious to urinate, and then hurriedly said, "Don't dare, don't dare." ”

Hei Yaotian smiled.

"The way you look makes me want to believe that you can't do it, in fact, it's normal that you don't believe it, if it's really a black ball here, then I don't believe it either."

"Do you think this little black ball is nothing more than dirt or black stones?"

Chen Zisheng and Li Jianqiu nodded noncommittally.

"Then you are very wrong, you look at the various things next to this little black ball, there are also like black balls, and there are some different colors, which will make people mistakenly think that these are just small mud stones, but there is a big mystery in them, you are looking at them again."

Chen Zisheng and Li Jianqiu stared at the screen seriously again.

"The smoothness of this little black ball is more reflective than the stone and dirt next to it, this is absolutely impossible to be a natural formation, and even if it is, it is absolutely impossible to be mud or stones, this must be man-made."

Li Jianqiu nodded, but still had some questions.

"Even if it's artificially grinded, then it may be someone else's hobby, which still can't prove anything."

This time, even Chen Zisheng nodded in agreement.

Hei Yaotian smiled again.

"Wrong, you're wrong, it's certainly not someone else's hobby, you see."

Hei Yaotian fast-forwarded to a time period when he stopped, only to see a group of students rushing to watch the play, and then the fastest student stepped on the little black ball, and then almost slipped, the little black ball flew out, and then fell to the ground again, and then it was bounced away, as for how high it was bounced, I don't know.

Hei Yaotian pressed pause here.

Chen Zisheng and Li Jianqiu were still puzzled.

"What's wrong with that?"

Hei Yaotian was speechless about the IQ of the earthlings.

"Look at how high this should be able to bounce when it lands."

Chen Zisheng and Li Jianqiu looked at it carefully again, according to what is converted into elastic potential energy, according to the &#♀ojbk principle, this should be able to bounce to more than half of the height when it flew out, etc., more than half?

More than half?!

Chen Zisheng and Li Jianqiu suddenly realized that this was definitely not a stone or dirt, this probably, probably, should be an elastic ball!

Chen Zisheng and Li Jianqiu still felt that something was wrong.

"No, old five, even if it might be an elastic ball, then someone could have thrown it here." Li Jianqiu asked again, and Chen Zisheng nodded again.

"Alas! Therefore your land...... Uh, you two are just too careless and irresponsible, asking you to help me carefully check the surveillance, you guys are almost a waste of the night. ”

"I actually not only checked the monitoring of the current time period, but also checked the previous time period, and I found that basically no one has been here in the past three days, and even if there is, they are here to cheat, and there is not even a black ball on the ground in those three days! However, there were a few black balls on the night before the incident, which was obviously added by someone on purpose, so this little black ball must have been added by the black hand behind the scenes! ”

Chen Zisheng and Li Jianqiu were really convinced of Hei Yaotian, and they couldn't take it, they didn't expect this Hei Yaotian's IQ to be so high.

"But even if that's the case, it doesn't seem to be useful, what's the use of this?" Li Jianqiu asked again.

Hei Yaotian raised his forehead, he really didn't know the IQ of the earthlings, but he was also a little interested in the black hand behind the scenes.

"There is only one reason for the mastermind behind the scenes to do this, that is, to make sure that Shen Ziyi is dead or not, this is a person who sees is believing, and only when he sees it with his own eyes can he believe it, so this assassination will not succeed, the mastermind behind the scenes will definitely continue next time, and next time, he will definitely use that little black ball or something else to monitor, and when the time comes, as long as he catches out the things he uses to monitor, then he will definitely be able to find the location of the mastermind behind the scenes by inputting the aura into it!"

Li Jianqiu began to disbelieve it again.

"How do you know you're going to find it?"

Hei Yaotian was speechless, he was completely speechless, but he didn't expect that the earthlings were really short-sighted.

"In the process of making this ball, you can leave no fingerprints, but there will definitely be remnants of the aura of the black hand behind the scenes, and then you can find the location of the black hand behind the scenes by using the aura finder to input your spiritual power into it."

Li Jianqiu didn't understand it again.

"What the hell is this aura seeker?"

Hei Yaotian had forgotten that the Aura Seeker was something that only the Black Moon Empire had, and even other empires might not have it.

"What about this aura seeker, simply put, it is a tracker, as long as the aura on the item is input to the tracker, and then its own aura is input to the finder, you can know the location of the aura itself in the tracker, but there is a premise for this, then the soul level must be higher than the level of the person being tracked, otherwise it will be useless, and it may be counterattacked."

If Dr. Zhang was here, he would definitely be shocked, because the Reiki Seeker is exactly what Dr. Zhang is studying now!

Chen Zisheng and Li Jianqiu have nothing to say, this aura seeker ...... So awesome?!

In fact, they and Hei Yaotian didn't know that this aura seeker was actually only available in the royal family of the Black Moon Empire, and there were only three of them! There is one Demon Lord, one Hei Yaotian, and one is Hei Yaotian's second brother.

Chen Zisheng laughed loudly:

"Now that we know the goal, let's go back to sleep, I'm going to die."

"yes, yes, it's so late, go back to bed."

Hei Yaotian also agreed, after all, he had found a starting point, so go back to sleep.

After Hei Yaotian and the others left the monitoring room, the staff guarding the monitoring room showed a weird smile, and then took out his mobile phone and dialed a number.

"Zhang Gongzi ......"
