Feather Wind made a total of six such marks within a hundred meters around the yard, as long as anyone maliciously appeared here, then these snake eyes would immediately send out the images, of course, these images can only be seen by Feather Wind, and his eyes can share the resources of these "snake eyes".

However, this kind of enchantment will not last too long, and it will disappear after a day at most, so if you want it to work for a long time, you still have to set it up every day. However, that requires a large amount of "War Spirits".

As a negative path, there is a "spiritual sea void" in everyone's body, which is the center of power of the negative path, and there is a "spiritual prison" in it.

There may be multiple spiritual hells in a person's "Spirit Sea Void", just like there are so many planets in one universe, and the existence of spiritual hells is like the planets one by one, but they are also a space in themselves.

And the so-called "spirit hell" is the place where the war spirit of the negative Daoist is stored, and different forms of war spirit are stored in different spirit prisons.

The Hell is a different dimension, this space is theoretically infinite, and the existence of each Hell is responsible for storing a special power. For example, "Fire Hell", "Ice Hell", "Summoning Hell" and so on.

However, it is the "Sealing Boundary" in the "Spirit Sea Void" that is responsible for the promotion of the power of the negative Dao.

The so-called "sealing boundary", figuratively speaking, is a door that exists in a space, and each time a door is opened, the space will expand by one layer, and the realm of the negative path will also be raised to a higher level.

Of course, among these doors, there are gates and small doors, and each time a "small door" is opened, a "period" will be promoted, and each "door" opened will be upgraded by a "rank".

Every two "small gates" is a "gate", so each rank of the negative path is divided into the early stage, the middle stage, and the late stage.

Therefore, if the negative Dao person wants to improve his level, he must constantly open the "Sealing Boundary" in the Spiritual Sea Void, and no one has explored whether there is an end to this space, or where the end is.

Within the "Spiritual Prison", there is also this kind of "Sealing Boundary", however, the Sealing Boundary in the Spiritual Prison changes with the change of the Spiritual Sea Void, that is to say, as long as the "Sealing Boundary" in the Spiritual Sea Void is continuously expanded, then the sealing boundary of each Spiritual Prison on the negative Daoist will also be opened accordingly, and the attributes and strength in the Spiritual Prison will increase with it.

However, some existing spiritual prisons are not sealed, and if there is no sealing in a spirit prison, then it means that the power in this spirit prison cannot grow with the spirit sea, and it is called "necromantic prison".

Therefore, the key to the improvement of the strength of the negative Daoist lies in expanding the space of the "Spirit Sea Void", that is, constantly opening up the "Sealed Realms" that exist in it through cultivation!

Those who lose the path rely on unleashing the power within the "Spiritual Hell" to fight!

Therefore, if you want to become a negative Daoist, you must first cultivate the "Spirit Sea Void".

And the war spirits in each "spirit prison" are limited, and if the power in the spirit prison is exhausted, as a negative path, it will be impossible to fight.

Now there are two spiritual prisons in Yu Feng's body, one Hell Dao Spiritual Prison, and one Shura Dao Spiritual Prison, Shura Dao was originally known for his physical skills and speed, and now with the cooperation of Hell Dao "Snake Eyes", this feature is even more vividly played, which is very in line with Yu Feng's combat habits, and he is now thinking about how to use these two spiritual prisons more exquisitely.

"Is this the 'Thousand Miles Imagery'?"

At this time, a low and hoarse voice came from behind Feather Wind, and when Feather Wind turned his head to look, he found that it was the black cat Purr.

Yu Feng's eyebrows jumped, and he said, "You can say anything accurately, you are really not simple." ”

"You're not simple, as far as I know, there are very few people who can develop this kind of advanced technique. I'm afraid that only those who came out of the war in the time of great chaos will be able to master. Also, although I can see that this is a type of 'image transmission', I don't know exactly what kind of technique it is. ”

Yu Feng smiled and did not speak.

Black Cat continued, "However, I know that this is both an advanced reconnaissance technique and an extremely dangerous assassination technique. ”

"Oh, why do you say that?" Feather Wind made a gesture of inquiry.

"Hmph. The black cat groomed his beard with his paws and sneered: "I said a long time ago that you are a very hypocritical person, so let me expose you." ”

At this time, the black cat stared at Yu Feng with glowing eyes and said, "This technique can not only transmit on-site intelligence, but also, you and these runes are one and the same. In other words, you can use them to get to the scene in an instant. If you're passing by someone, you can pop up next to him and stab your weapon at his vital point until they die. ”

"I didn't expect you to know more than I thought. ”

"Don't rush to interrupt. This technique is derived from the assassination technique of the Red Dark World, but this one is modified because it contains elements of the Hell Path. But that's enough to show that you used to be a killer!" said the black cat.

Feather Wind smiled and said to the black cat, "Hehe, you're really joking. If I were a killer, I would have killed you now, lest you tell the secret. ”

The black cat snorted disapprovingly and said, "If you want to kill me, you are welcome at any time." I'll keep an eye on you, though. ”

"Heh, that's a nice thing to say, where were you when Hanano Mustard almost gave me his life today?" Feather Wind mocked.

"Are you talking about the crash? Of course I saw them all, but I just wanted to take the opportunity to see how many you had. If you had turned into a meatloaf, then I would have done it. ”

Yu Feng was shocked in his heart, it turned out that he knew everything and saw everything.

"As it turns out, your strength is really beyond expectations. ”

Yu Feng smiled and said, "I'm afraid you think highly of me." ”

"Hmph, I don't want to argue with a hypocrite like you, I'm going to sleep. With that, the black cat walked away with a slow step.

Yu Feng looked at the back of the black cat and said to himself: "Why does this guy sleep during the day and sleep at night, it's the right thing to take advantage of the night to get those mice." ”

Hua Zhiji has already given Yu Mengling medicine, but the latter still closes his eyes and lips tightly, and there is no sign of waking up, Hua Zhiji is secretly anxious in her heart, she doesn't know if Yu Feng will use that method to be effective, Xiaoyu will not be able to wake up again.

At this time, Yufeng knocked on the door, and Hanakei shouted "Come in", she was about to look for Yufeng.

"What's going on, I haven't woken up for so long, there won't be any problems, right?" said Hanakei worriedly.
