The panic and fear brought about by the darkness for a moment seemed to be affected by Sun Xiaoxi on the other side of the phone, but due to the characteristics of his profession, Sun Xiaoxi seemed quite calm when he encountered such a situation, and he was very little affected.

However, Wu Yu was different, he was originally concentrating on grabbing Sun Xiaoxi's hand, and Wu Yu, who was already very poor at responding to emergencies, was a little panicked for a while.

Sun Xiaoxi's comforting voice came from the phone: "Husband, is there a power outage over there?" ”

Hearing Sun Xiaoxi's voice, Wu Yu's mood calmed down somewhat and breathed a sigh of relief: "En! Maybe there's something wrong with the wiring at your police station! Don't worry, I'll smear my blood on your hands first and see if I can help get rid of the ghost wall. ”

Sun Xiaoxi on the other side of the phone was a little puzzled: "Husband, don't give me first aid, it is impossible for the police station to have a power outage, and our power supply equipment is connected to a total of three power supply stations with different lines." If any power supply line is disconnected, it will automatically switch to another power supply system within 0.1 seconds, and there may be something wrong with this. ”

Wu Yu couldn't see anything in the dark, so he could only rely on the light of his mobile phone to shake around, but an ominous premonition made Wu Yu a little uneasy: "It's okay, maybe the three power supply lines are broken!" Even if someone deliberately sabotages, there are so many police officers in your team, they should be able to handle it, or it is important to save you. ”

Sun Xiaoxi's heart was warm, so he didn't say anything more, just a simple 'En! 'Sighed. It's hard to understand the mind of a little woman, but not everyone has the opportunity to play such a romantic plot with their lover.

Wu Yu's finger wound that he had bitten before was no longer bleeding, but now it was obviously not cost-effective to bite another finger, so he simply squeezed out a trace of blood from the broken wound with his teeth and smeared it in the direction he grabbed Sun Xiaoxi's hand.

Sun Xiaoxi's voice on the other side of the phone seemed to be very calm: "I feel it, are you wiping something on my hands?" ”

Wu Yu didn't answer, but stared in the direction of his hand, since he could smear the blood, then the yang energy would move in this direction, and Sun Xiaoxi should be affected by the yang energy, so as to get rid of the ghost hitting the wall.

However, time passed minute by minute, and the blood was always smeared there in the direction of Wu Yu's hand, and Wu Yu couldn't help asking: "Daughter-in-law, do you see if there is blood on your hands?" ”

Sun Xiaoxi looked at his hand that was grabbed by Wu Yu, there was no change in the slightest, and he couldn't help frowning: "There is no change!" I just felt you move on my hands, but I haven't seen any blood until now! ”

Wu Yu looked at the blood stains floating in the air strangely, it seemed that things were not as simple as he thought, obviously this bit of yang energy had no impact on Sun Xiaoxi's environment.

I obviously relied on the yang energy of blood to get out of the predicament just now, but at this moment, it has no effect at all, does this so-called ghost hitting the wall still have the function of identification?

Sun Xiaoxi on the other side of the phone said calmly: "That's it, husband, I'll bite my finger and give it a try, will only my own blood have an effect?" ”

Wu Yu didn't know how to explain to Sun Xiaoxi, he didn't understand what was going on with this so-called ghost hitting the wall now, so he had to respond: "Okay! You can give it a try, but don't get too much blood, I'm not sure if it will actually work. ”

Sun Xiaoxi said 'En', but after about ten seconds, Sun Xiaoxi's voice came from the phone again: "Husband, it doesn't work!" I've smeared my own hands and yours with blood, but it doesn't work until now. Why don't I try to put blood on my forehead? ”

Wu Yu shook his head, although he knew that Sun Xiaoxi couldn't see it, but Wu Yu still shook his head habitually: "Don't try, the blood has yang energy, it doesn't have much to do with where it is applied, I guess it may be that the yang energy is not enough, I'll think of other ways, don't worry about it first." ”

Sun Xiaoxi is not in a hurry at the moment, it's not that Sun Xiaoxi has no heart or lungs, it's just that girls nowadays like excitement and romance, if you don't experience such a rare opportunity for a while, I'm afraid that there will be no chance in the future.

It is estimated that if Wu Yu knew Sun Xiaoxi's thoughts, he would definitely scold Sun Xiaoxi for lacking heart. However, Sun Xiaoxi obviously won't say this kind of thing, and women prefer to let the man they like worry about themselves.

Sun Xiaoxi gently comforted Wu Yu: "It's okay, you think slowly, as long as you don't let go, I'm not afraid." ”

Wu Yu was still a little moved by today's Sun Xiaoxi, after all, his daughter-in-law believed in herself, which was an affirmation for a man.

Wu Yu carefully analyzed the Yu Chen's experimental notes that he had read, and also analyzed the changes of yin and yang in the corridor. This method of testing the flow direction of yin and yang is very simple, according to the statement given by Yu Chen, if the qi of yin and yang is regarded as a kind of wind, then it only takes a weather vane to feel the change in wind direction.

This yin and yang energy can also be regarded as a kind of magnetic field, and the direction of the magnetic field is just a compass. This shows that no matter what you think of yin and yang. As long as there is something that can feel its transformation, but its own power is negligible, then it can be used to point the way.

Wu Yu thinks that he has not changed as much as Yu Chen. state, you have to carry all kinds of perverted things on your body when you go to the toilet. At this moment, to test the direction of yin and yang, Wu Yu can only test it in the way of Yu Chen, who he has learned.

There are actually many ways to check yin and yang in Daomen, but in Wu Yu's eyes, most of those methods are relatively suspenseful. For example, observing the mountains and leylines, or looking at astronomical stars, or hanging copper coins, none of the various methods seems to be reliable.

However, for people like Yu Chen, who neither believe in Buddhism nor Taoism, simple one plus one equals two is the way he has been using for a long time. For this kind of method of people who have no faith and always like to blaspheme, it happens that sometimes the effect is very good, and even the phenomenon of one plus one is greater than two often occurs.

Yu Chen's method is very simple, create a small yin and yang formation, take a look at the yin and yang directions of this small yin and yang formation, as long as you test it many times and from different angles, it is easy to calculate the overall yin and yang trend. This method has the same effect as the compass, the only difference is that the compass does not drip blood.

Ordinary people are not idle, nothing to carry on their bodies, so Wu Yu had to use his own blood to act as the yang part, as for the yin part, Wu Yu had to use his own fingernails to pick off some wall ash from the wall.

Originally, it was impossible for the wall ash to attach yin qi, but as long as metal was used as a medium, if the other end gathered yang, then the opposite direction would naturally gather yin.

The only thing on his body that is metal is the key, so Wu Yu's next move is very difficult, holding Sun Xiaoxi's hand on one side and holding the key with the other. Then he took Sun Xiaoxi's hand to drip blood on one end of the key, and also used blood stains on the top of the key to draw a pattern that could gather the sun.

Although this pattern is a simplified version of Yu Chen, there are not a few strokes in total, but because the place on the key is too small, Wu Yu painted while comforting Sun Xiaoxi, and it took more than ten minutes to roughly draw the pattern of Juyang.

The wall ash is easier to get, but Wu Yu is more worried about the monitor at the end of the corridor, maybe a few policemen will come over in a while, and arrest him for vandalism.

Everything was done Wu Yu couldn't wait to throw the key on the ground, but it was very unrealistic to rely entirely on the change of yin and yang to rotate the key, Wu Yu had to rotate the key in place, and could only wait for it to stop slowly, only when it was about to stop, the effect of yin and yang qi would be reflected.

Holding Sun Xiaoxi's hand, Wu Yu was surprised that he didn't feel Sun Xiaoxi's anxiety, and when Sun Xiaoxi on the other side of the phone knew about Wu Yu's experiment, he even told Wu Yu to be patient with the experiment.

After turning it a few times, the direction of the key representing yang energy only thought about Sun Xiaoxi's direction, and the opposite direction pointed to a door not far away.

Wu Yu pulled Sun Xiaoxi to the door quickly, only to see that the three big characters on it almost didn't make Wu Yu angry. After walking in the ghost wall for a long time, I was looking for the evidence department, but I didn't expect that the direction of the key's yin qi was pointing here.

Seeing such a phenomenon, a new idea immediately appeared in Wu Yu's mind, that is, a certain thing that gathers yang originates from Sun Xiaoxi's body, and another thing that gathers yin is in the evidence department, and a phenomenon of yin and yang circulation is formed between the two, so the ghost wandering nearby wanders between the two, and the so-called ghost hitting the wall phenomenon is formed.

Wu Yu simply told Sun Xiaoxi his thoughts, and asked Sun Xiaoxi to follow him into the evidence department, as long as he found the thing that gathered yin and blocked the circulation of yin and yang between it and the thing that gathered yang on Sun Xiaoxi's body, it was estimated that Sun Xiaoxi would get rid of the ghost wall.

Sun Xiaoxi naturally listens to whatever Wu Yu says, anyway, she is now in a dreamy state of invisibility, it doesn't matter if Wu Yu pulls her into the men's toilet, no one can see her anyway.

With Sun Xiaoxi's consent, Wu Yu hurriedly pulled her into the evidence department. As soon as he entered the door, Wu Yu saw the policeman surnamed Yang tonight, and remembered that it was Sun Xiaoxi who handed over the jade pendant to this policeman.

Wu Yu was about to say hello, and the policeman surnamed Yang came over with a smile: "Xiao Wu, right!" I remember you, Xiaoxi's boyfriend. ”

Wu Yu said: "Yes, yes, hello Officer Yang, I want to help Xiaoxi find something, can you help me find it?" ”

Officer Yang frowned: "What is your name Officer Yang, you are the same as Xiaoxi, just call me Uncle Yang." However, the evidence in the evidence department is not something that can be moved casually, and what Xiaoxi wants must be signed by herself. ”

Wu Yu hurriedly handed over a cigarette: "Uncle Yang, you misunderstood, Xiaoxi said let me take a look, just describe the general appearance, I will take a look, I will not take it away." ”

Officer Yang nodded: "Oh, that's no problem, if you want to see something, I'll help you get it." ”

Wu Yu thought about it, since Sun Xiaoxi's body can gather yang, it means that the problem must lie in the jade pendant on her body, since the pattern on the jade pendant is the same as the pattern on other antiques, then there must be another thing to gather yin. Thinking of this, Wu Yu hurriedly said: "It's the batch of evidence you brought back from the antique store today, Xiaoxi asked me to see if there is anything she said." But I can't describe what it looks like, so I can only ask you to show me all the evidence. ”

Officer Yang did not doubt him, not to mention that the man in front of him was the director's son-in-law, so there would be no problem if he thought about it. However, just as he turned around to pick up the batch of evidence brought back from the antique shop, he suddenly felt an unprecedented cold air hitting the shop, and the next moment Officer Yang fainted to the ground, and the last scene was only Wu Yu behind him.
