That's right, how did I forget this!Ao Feng slapped his head, secretly scolded himself for being confused, increased the output of the waveguide, and wiped out the black substance. Lucario: "Try it, can you help these elves expel the black gas, be careful." ”

If his own waveguide works, then Lucario's waveguide should also work, and if so, he will be able to release Lucario and the path.

Lucario nodded, walked over to an elf, and carried the waveguide. The result was not bad, it was easy to expel the black gas, Ao Feng breathed a sigh of relief, simply, there are still elves who restrain these things, relying only on himself, the energy is too limited.

Close your eyes and spread the waveguide out, it doesn't matter, it almost scared Ao Feng to death, this is still a water city? This is obviously hell. Under the detection of the waveguide, the whole city is completely shrouded in black gas, which is not visible to the naked eye, but it can be seen clearly under the waveguide.

Originally, he also wanted to find out how it spread, but he didn't need to check it this time, the air was the medium of transmission, and when it spread out from the center of the elves, Ao Feng found that almost all the elves had black gas in their bodies, but most of them did not mutate. Judging from the energy intensity in their bodies, it should be the relationship of strength, suppressing these black gases, but with the accumulation of black gas, sooner or later there will be a day when they will be controlled, and at present, this process is very fast.

Ao Feng could only detect the range of the surrounding kilometers, and after looking at it, he turned his gaze back, and when he saw a few elves around, he was stunned for a moment, and a light blue light emanated from around Lucario's body, isolating the black qi, presumably because of the effect of the waveguide. This was still what he expected, but the two elves who had just been cured were a little different, they also had a light blue light on their bodies, resisting the black qi, but this light was gradually weakening.

As for people, these gases will not remain at all, and they do not seem to threaten humans at all.

Residual waveguide, Ao Feng muttered, and then looked at Latios and Latias, the two elves do not have black gas in their bodies at present, and they are protected by blue and red light respectively, although they are also constantly being eroded, but it is no problem to resist for a while.

"You stay here, let's go out and investigate. Ao Feng said a word to a few people and walked out.

The two women glanced at each other, and didn't say anything to follow, they knew that following the past would not help, and might even drag Ao Feng down.

There was no one on the street anymore, and the path was also released: "Let's split up, detect the place where the black gas is most concentrated, and solve the source, and this situation will be solved." ”

The two elves nodded, scattered, spread their waveguides, and swept swiftly across the street. Since there is no one left, there are many more convenient places for them to move. However, Ao Feng still detected a lot of waveguides hidden in various places, it is estimated that they are people in the family who came out to investigate, they don't care about them, there are no clear clues, these people want to investigate clearly It is estimated that it will take a long time.

After running around, Ao Feng's brows were locked deeply, he didn't find anything, he didn't find anything, the black gas in the city was scattered everywhere very evenly, and he couldn't see where the source was.

Soon the two elves also returned, and the result was the same as Ao Feng, and nothing was found.

The clue was broken again, and Ao Feng couldn't think of a better way right now, so he simply went back to the elf center first and found a few more people to figure out a way together. Retrieving the two Pokémon and reducing some of their consumption should be of greater use later.

"Brother Feng!" Seeing Ao Feng come back, the two girls greeted him, and the gloomy look on Ao Feng's face made them all startled.

Ao Feng shook his head and sat on the elf sofa: "I haven't found anything, I don't know if the source is too cautious and hidden too deeply." ”

"Then what should I do?" Miss Joy said worriedly, now there are more and more infected elves, with her treatment is completely useless, if it can't be solved as soon as possible, I'm afraid that the elves in the entire city will suffer, and if it continues to develop, there will definitely be a large number of people migrating, and in the future, I'm afraid that the water capital will become a dead land.

"I just can't figure out a way, so I came back to you to think about it. Ao Feng's face was still gloomy, he knew that it would be difficult for them to give a better way, so he could only hope for the three major families and the police.

"Brother Feng, let's eat first. It was getting dark quickly, but Ao Feng was still at a loss, and this feeling of not knowing who the opponent was or even where he was was really uncomfortable.

Ao Feng smiled bitterly: "You eat first, I'm not hungry now." ”

"Eat a little, your waveguide is the only thing that can restrain the black gas at the moment, if you are going to starve, we really can't do anything. Kerr persuaded.

"Okay. Ao Feng got up, Ke'er was right, if you find someone, you won't have the strength to do it, and it will hurt.

As soon as Ao Feng ate a little something, Miss Joy ran over: "Ao Feng, the speed of mutation of the elves that were not completely infected has accelerated!"

"What!" Shocked, Ao Feng stood up, didn't go to investigate the situation of those elves, and directly turned on the waveguide detection.

"Is night the time to be active?" Ao Feng raised his eyebrows, not afraid that you would do it, but afraid that you would not come out. At this time, in the waveguide detection, the black gas that was not very thick seemed to cover the sky at this time, this gas was really rich, and the changes of the elves were normal.

"I'll search again. Sensing the opportunity, Ao Feng no longer hesitated, immediately released the two elves, left the elf center, and said before leaving, "You wait for me here, no matter what the situation is, it is important to protect yourself, you must not release the elves, notify me if there is any situation." ”

"Be careful. The two women asked.

Ao Feng waved his hand: "Got it." ”

As he judged, if the black qi was thick, then the source must be constantly releasing black qi, so it would be easy to find its location.

"Over there?" Ao Feng paused, his gaze on an abandoned factory at the back of the mall. He didn't rush in, and it was dangerous to go in by himself without knowing what kind of strength the other party had.

"I've found the source, and I'll send someone to the factory at the back of the mall, remember, no one is allowed to carry elves, and the use of thermal weapons is enough. Ao Feng took out the phone and informed the people of the family.

"Understood!" Although the steward was surprised that Ao Feng had caught the other party's hiding location so quickly, there was no problem with his own execution ability.

Ao Feng just put down the phone and didn't put it away, the phone vibrate, in order to prevent being discovered by the other party, Ao Feng had already turned off the ringtone.
