(Ask for collections, ask for recommendations, ask for rewards, thank you!) ）

In the end, Lin Jianfeng chose to trust his instincts.

In addition, he found that this time the ghost qi was slightly different from the last time, after the last time the ghost qi was swallowed by the ghost devouring sword, it disappeared directly, and this time the ghost qi, under his observation, seemed to have a faint source.

Lin Jianfeng's right hand shook, and the Ghost Devouring Sword, which had been shaking, immediately turned into a flying sword and flew above the wisp of ghost qi, devouring that wisp of ghost qi in the blink of an eye.

He didn't withdraw the Ghost Devouring Sword, but carefully observed it with his ghost eyes for a while, and then his eyes lit up, and he said to himself: "Sure enough, this wisp of ghost qi is not a rootless ping, but has a source, no, I have to check it!" ”

It turned out that in the place where the ghost qi disappeared, it was only a few breaths before a faint wisp of ghost qi reappeared, and according to his check, there was no trace of the ghost around at all, so it was obvious that this wisp of ghost qi was coming from other places.

But soon, Lin Jianfeng frowned slightly, because whether it was relying on his spiritual sense or using the ghost eye talisman, he could sense that this wisp of ghost qi had a certain source, and he had already done his best, if he wanted to follow the ghost qi to trace the source, he was a little powerless.

Suddenly, Lin Jianfeng caught a glimpse of the Ghost Devouring Sword that was still leaping in the air and wanted to continue devouring the ghost qi, and immediately moved in his heart: "Yes, I can completely use the Ghost Devouring Sword's sensitivity to ghost qi to trace the past." ”

The more he thought about it, the more correct Lin Jianfeng felt, and immediately pinched the trick with both hands, and pointed his right hand into a sword at the Ghost Devouring Sword, and the Ghost Devouring Sword was immediately under his control, and found the direction from which the wisp of ghost qi came from.

"However, before you go, you still need to do some disguise!"

Lin Jianfeng took out a spirit rune from the pouch, stretched out his hand and slapped it on the Ghost Devouring Sword, and immediately the Ghost Devouring Sword disappeared, in fact, the Ghost Devouring Sword was still in the air, but it was just invisible to the naked eye.

The name of the spirit rune just now is called the eye barrier talisman, as the name suggests, it is the meaning of the eye barrier method, it can be used to blind the eyes of mortals, it is very convenient and easy to use, and like this spirit rune, there are many in the primary spirit rune encyclopedia, Lin Jianfeng thought that he might use the spirit rune, and he refined a few pieces, and this eye charm was the first time he used it.

After covering up the traces of the Ghost Devouring Sword, Lin Jianfeng's technique changed, and the Ghost Devouring Sword suddenly devoured the ghost qi that was faint but was coming from it continuously, and flew quickly in the direction of the source.

The running speed of a person is not comparable to the flying speed of the flying sword, and he is currently in the city, so under Lin Jianfeng's control, the speed of the Ghost Devouring Sword's flight is not fast, and he maintains the speed at which he walks quickly.

In the city, in addition to people, there is no shortage of all kinds of tall and dense buildings, so Lin Jianfeng has to control the Ghost Devouring Sword from time to time to turn and go around, which inevitably wastes a lot of time.

Finally, near a huge warehouse, Lin Jianfeng controlled the Ghost Devouring Sword and stopped, because there was no need for the Ghost Devouring Sword at this time, he could already sense that there was constantly ghost qi coming out of the warehouse in front of him.

Therefore, for the sake of safety, when there was still some distance from the warehouse, he temporarily put away the Ghost Devouring Sword, after all, this blinding talisman can blind mortals, but for cultivators, it is useless at all.

"This should be a warehouse near the port, but it stands to reason that there should be many people moving in and out of this kind of place at any time of day and night, and these people are generally in the prime of life, and their blood is vigorous, so it is generally impossible to have any ghosts?"

Lin Jianfeng was a little puzzled, the port is not only a state organ, but also has the protection of national luck and official energy, all evils are avoided, coupled with the impact of human flesh and blood, how can there still be ghosts, and it is constantly transmitted?

After thinking for a while, Lin Jianfeng was fortunate to wander around this port area, and soon he had a goal.

"Hey, master, I want to ask you something, I don't know if it's convenient for you?"

Lin Jianfeng came to a driver who was leaning on the side of the car, watching the workers unload, took out a box of high-grade cigarettes from his bag that he would only use when doing errands, handed over a cigarette and asked very politely.

"Yo roar, purple smoke, this is good smoke, I want to taste it!"

The driver was almost forty years old, and when he saw the cigarette handed over by Lin Jianfeng, his eyes immediately lit up, and he quickly took it, and took a deep breath under his nose as he spoke, full of intoxication.

After a few breaths, the middle-aged man opened his eyes with satisfaction, and couldn't wait to put them in his mouth to light, and then spit out the circles under his eyes, and said politely: "Young man, if you have anything you want to ask, just ask!" ”

Lin Jianfeng knows that for dealing with such a train driver, there is nothing that cannot be solved by a good cigarette, if it can't be solved, then there is another pack.

"This master, I want to ask, do you know what that warehouse over there is for, I see that this warehouse here of yours has never heard of it, and it keeps cars coming in and out, why is that warehouse so quiet?"

As he spoke, Lin Jianfeng pointed to the warehouse where there was a ghost qi coming out, and then waited for the middle-aged man's answer.

"Hey, what am I talking about, you want to inquire about that warehouse?"

When the middle-aged man heard Lin Jianfeng's words, he shook off the cigarette ash and said disapprerovingly: "This warehouse was originally very busy, but three months ago, I don't know what happened to be rented by others, and since then, the door has been closed like this, and I have never seen people and cars enter or leave." ”

Then, with an indignant expression on the middle-aged man's face, he continued: "Do you say that this rich man can be so willful? Such a good warehouse, and it is in the port area, and the business is continuous every day, and it is really a waste to put it there with the door closed now! ”

Lin Jianfeng got the information he wanted, and after casually saying a few words to meet the middle-aged man, he turned around and left, looking for a shadowy corner where the front of the warehouse could be observed, and looked at it carefully.

It's just that, as the middle-aged man said, there is no light in this warehouse, and no one or vehicle is approaching, as if it is deserted.

"If you look at it like this, there's no way to get any results, it seems that I still need to sneak in and check it out!"

This is the conclusion that Lin Jianfeng came to after observing for half an hour.

So, taking advantage of the darker and darker night, Lin Jianfeng retracted the breath and mana on his body, and his figure flashed, and he suddenly disappeared into the shadow of the corner.
