With the arrival of the sun and the moon on the same day, Shi Fu also successfully climbed the arrow tower in the west of the city, holding the pearl on the roof with his right hand, looking in the direction of the main hall.

I saw that on the roof of the original hall, a crack suddenly appeared, as if it was a different dimensional space, Shi Fu fixed his mind, shook left and right in front of his eyes, and a pair of glasses appeared instantly, when Shi Fu looked at the crack again, he found that a ghost gas did gush out of the crack, seeing this scene, Shi Fu smiled, his judgment was really right, this ghost unicorn must be in this half of the room.

After determining the direction, Shi Fu used another force under his feet, and used the thunder instantaneous body method, and his whole person arrived in front of the main hall in an instant, at this time it was already the time to close the hall, so there was no one in front of the main hall, Shi Fu used the Dengxian leap again, and rushed to the space crack with a few arrows, and then he held his breath and stuck his head in.

A small space appeared in front of Shi Fu's eyes, it was empty, there was nothing, but Shi Fu saw a lot of black gas from his glasses, Shi Fu thought about it, his whole body got in, and the black gas suddenly attached to his body, and Shi Fu immediately felt a feeling of numbness.

He raised his arm, and saw that this black qi was constantly eroding his skin like a living thing, but the body of the Ancestor Saint was so amazing, the black qi could not break through at all, and could only continue to rub on the periphery.

When Shi Fu saw this scene, he felt more confident, after all, he didn't know the other methods of the ghost qilin, but he was still clear about the corrosiveness of the so-called ghost qi, and the current situation meant that he had at least the strength to fight.

Subsequently, he began to search in the room, this half of the room is not big, but Shi Fu still looked for a long time, it turned out, the half room is just a visual feeling, the actual area is very large, this is the design of the king of people back then, so that it is a spell that turns into nothingness, although the whole room looks small, but when you walk up, you will find that there is no margin at all, and this can be used as a small world.

Shi Fu finally found some traces of the ghost unicorn in the west side of the room, there were a few scales and hairs, Shi Fu sealed these things with a sealing array, and then put them in the bag, he didn't dare to put them directly, otherwise the little belongings in the bag would be gone.

Then, Shi Fu searched in the half room for a long time, he found some problems, the ghost qilin seems to be no longer here, whether it is the intensity of the black gas or the food remains such as bones found here, they all show a certain age, Shi Fu touched his chin and thought, he just wanted to search again, he found that the space crack had begun to close, he didn't want to stay here for a long time, so he used a thunderbolt and rushed to the entrance.

Finally he looked back at the room again, and went out, but he did not notice that there was an oil lamp shining in the northeast corner of the house.

After Shi Fu walked out of the spatial crack, he found that the sky had completely darkened, and turned his head to look at the spatial crack, at this time the crack had been completely closed, Shi Fu did not stay long, the thunder was of instant use, and he disappeared in place in an instant, and when he reappeared, it was already on the road.

Shi Fu wanted to contact Wang Longqiang to see if he could test the black ghost qi, he just took out the big brother and suddenly thought of something, if he contacted Wang Longqiang, it must be Qin Yuanfeng to pick him up, as soon as he thought of this, he put the big brother away, and then hurried away with a thunderbolt and came to the gate of the military base.

The soldiers standing guard and Shi Fu knew each other, so they directly let Shi Fu in, and when they walked to the gate, Shi Fu did not rush in, but took out the eldest brother and dialed Wang Longqiang's number: "Hey, is it Uncle Wang? I have a clue, you quickly send someone to pick me up." After saying that, he hung up the phone directly.

After waiting for a while, the door opened, and a small car drove out, the driver was Qin Yuanfeng, he was stunned when he saw Shi Fu standing at the door, and then stretched out his hand and pointed at Shi Fu and asked, "...... You...... How did you...... Why are you here?"

Shi Fu smiled and said: "I knew that you must have come to pick me up, so I came by myself, although it took a little mental power, but I am willing, hahaha." After speaking, Shi Fu walked in directly, leaving Qin Yuanfeng messy in the wind.

After Shi Fu walked into the base, he came to Wang Longqiang's office with ease, and said as soon as he opened the door: "Uncle Wang, I didn't say you, Qin Yuanfeng is so difficult to arrange!"

Wang Longqiang raised his head when he heard this, and asked suspiciously, "Why did you arrive so quickly?"

Shi Fu waved his hand and said, "When I called at the door, I knew that it must be Lao Qin who was driving." ”

Wang Longqiang smiled awkwardly: "Hey, this is not his father's decision, and I can't refuse, and as soon as I heard that you were coming, this guy behaved very positively." ”

Shi Fu sighed and said, "Forget it, let's get down to business." As he spoke, he opened his backpack, then took out a paper bag and continued to Wang Longqiang: "This is what the ghost unicorn is on, you can take a look at it and test it for the scientific research." ”

Hearing this, Wang Longqiang quickly stood up, walked to Shi Fu's side, looked up and down, left and right, and asked, "Have you found the ghost qilin?"

Shi Fu waved his hand and said, "No, I just found its former nest and went in to get these things." ”

Wang Longqiang stretched out his hand to take the paper bag, but Shi Fu withdrew the paper bag back and said: "This thing is too corrosive, only I can bear it, you can take me over." ”

Wang Longqiang nodded, and took Shi Fu to the scientific research room together, after explaining, Shi Fu put on protective clothing and walked into a closed room, this room is surrounded by thickened walls, which are usually used to deal with ***, there is no glass in the room, and the outside and inside are all seen through the camera, although it is not very clear, but it will be able to see.

Shi Fu walked to the middle of the room wearing heavy protective clothing, he slowly opened the paper bag, and then, with his right hand on the scales, the seal was unsealed, and a black gas instantly emerged, the protective clothing on Shi Fu's body was like paper paste, and it was completely corroded in a few minutes, Shi Fu became naked at this time, he looked at the camera and shouted: "Don't let Qin Yuanfeng see it." ”

But he didn't know that at this time, Qin Yuanfeng was already laughing like crazy in the office outside, Wang Longqiang looked at Qin Yuanfeng, looked at Shi Fu through the monitor, and then held his forehead with one hand.

In the laboratory, Shi Fu took out some experimental supplies from the corroded protective clothing, after several tests, these black gases are quite corrosive, even steel can corrode off, but they are immune to one thing, that is, styrofoam, it seems that black gas hates the material of styrofoam very much, when Shi Fu approaches the black gas with styrofoam, it will always avoid, instead of continuing to corrode, as if conscious.

In the next ten minutes, all the researchers in the base devoted themselves to the study of black gas, they made a cage out of styrofoam, and then put various sensors into it, although it was corroded after a few seconds, but it was still possible to collect some data, this back and forth, hundreds of sensors were broken, but the data was also collected, Shi Fu looked at the black gas data in his hand and fell into thought.

According to the analysis of the instrument, this kind of black gas is actually a kind of microorganism, but their mass is very low, and their body size is super small so they can float in the air, but this black gas creature is particularly fragile, every time something is corroded, it will die in large numbers, and the way of death is to dissipate directly, which is why the forensic doctor can't check anything when examining the victim's body, everyone has dissipated, and what else can be detected.

After that, Shi Fu sent the information to the Wood Guards and the Water Guards, because he already had experience, so, along with the information, Shi Fu also attached a few samples.

After doing everything, Shi Fu found a conference room, sat on the sofa, and fell into thinking, according to Old Man Liu's story, when they found the ghost unicorn, it should have been decades ago, at that time the ghost unicorn must have lived in half a room, this has been proved when Shi Fu searched for half a room, and then, the ghost unicorn didn't know why he left half a room, so where did it go back? Thinking of this, he suddenly got up and ran out of the conference room.

Wang Longqiang was just about to go back to the office at this time, and as soon as he opened the door, he saw Shi Fu running over in a panic, and he hurriedly stepped forward and asked, "Little Fu, what's wrong?"

Shi Fu pulled him to the office, and said as he walked: "Quick, Uncle Wang, let's hurry up to your office, you find out the map of the northern capital for me, I suddenly remembered something." ”

Wang Longqiang didn't understand what Shi Fu meant, but he didn't ask much, and then, the two came to his office, Shi Fu took out all the information of the deceased, and Wang Longqiang took out a map of the northern capital and pasted it on the wall.

Shi Fu was looking at the information while holding a pen and drawing something on the map, and after all the information was over, he looked at the map on the wall and smiled.

Wang Longqiang looked at Shi Fu's expression and asked, "How is it?

Shi Fu nodded and said, "According to this result, we still have to thank the previous Death Organization." ”

Wang Longqiang asked suspiciously, "What does this have to do with them?"

Shi Fu smiled: "According to my analysis, a few decades ago, that ghost unicorn had been living in half a room in the Yellow Palace City, and then for some reason, where it left and disappeared since then, but two months ago, it suddenly appeared again, and this time it began to forage frantically, and there are only two reasons for this situation." ”

Wang Longqiang touched his head and said, "What are those two reasons?"

Shi Fu raised a gesture of one and said, "First, this guy is ...... pregnant. ”
