In fact, if it is usually placed when the shadow knife is not injured, it will not take much energy to deal with these yin spirits at all, because his exercises have a strong restraint effect on the yin spirit, as long as he consumes some more energy, he can wrap the special energy on the yin spirit, in other words, the shadow knife even had a period of time before to collect and find the yin spirit, in order to make some special secret weapons for himself. Trap these Yin Spirits in some containers in a special way, and release them in an instant when they are needed, when the enemy is unprepared. After the yin spirit is released, it will randomly attack the first person it encounters, and if it is cleverly chosen by chance, it is comparable to an artifact.

However, the number of this Yin Spirit is scarce, and once it is used, it must be kept away, especially the attack attribute of some enemies and friends of the Yin Spirit, which makes the use of this hidden weapon very restrictive. Therefore, the Shadow Knife is usually only used as a smoke bomb when escaping.

Speaking of which, when Fang Cai encountered the savage, it was not that the Shadow Knife had forgotten the killer weapon in his hand, but because the opponent's attack was so swift that he didn't give himself time to react to use this alternative method.

After carefully inspecting his current state, the Shadow Knife had already discovered that the Blood Gu that had broken through his own defenses had now completely penetrated into the depths of his body, and he would not be able to find it out for a while, and the current situation would not give him time to deal with that Blood Gu.

Recalling the situation when he was suppressed by the Blood Gu just now, Shadow Dao couldn't help but feel very lucky in his heart, if it weren't for the appearance of these Yin Spirits, he would probably still be struggling with the Blood Gu in his body now.

However, since he has regained the initiative in his body, he will naturally not repeat the mistakes of the past. So after thinking about it carefully, Shadow Knife turned around and sat back where he had just been, and at the same time, he saw Shadow Knife take out three swarthy porcelain altars from his storage bag, each of which was the size of a child's fist, and each porcelain altar had two pieces of yellow paper pasted on it. There is no one on the yellow paper, which is a little strange.

I saw that the shadow knife placed the three porcelain altars in front of him in turn, and then gathered his breath and exhaled towards the three porcelain altars in front of him. It is also strange to say that on the yellow paper that originally did not have any handwriting, after being sprayed by him, some very complicated patterns gradually appeared, only to see that as soon as this pattern appeared, the three porcelain vases that were originally motionless began to shake violently, and vaguely could feel that there was something in this porcelain vase that was about to rush out.

Seeing the vision, the Shadow Knife pinched a sword finger in his right hand, and his left hand slashed on the fingers of his right hand, and then blood splattered, and under the control of the Shadow Knife, the blood line actually drew a circle in the air, and rushed towards the outside of the firewood room through the broken window.

Looking at the three porcelain vases on the ground, they also let out a terrible whistling sound one after another, chasing the blood line and rushing out.

Take blood as a guide, chase the soul and ask for your life.

These Yin Spirits who were imprisoned by the Shadow Knife in a special way were already extremely familiar with the breath of the Shadow Knife, and they were eager to eat his flesh raw and drink all his blood, and the Yin Spirit was originally an aggregate of negative energy, and it would have extreme resentment towards the people who detained them. And that's exactly what Shadow Knife wants to achieve. He first used a porcelain altar made of that special method and material to subdue those Yin spirits, and then added a layer of seal on the outside, that is, the yellow paper.

If the yellow paper is not removed, then this seal will always exist, but if the yellow paper is torn off, the yin spirit inside will instantly break out of the jar, so the shadow knife thought of a way to temporarily limit the yin spirit in the jar, that is, to use a special method to make a small means in the seal outside the jar, so that the seal will gradually lose its effect with the passage of time, and then within this period of time, he will use his own blood as a bait to achieve the purpose of controlling the behavior of the yin spirit, if the yin spirit suddenly smells the blood of the enemy who killed him when the seal becomes weak, he will definitely fall into madness in an instant。

Then the matter is completely simple, as long as you use your own blood to lure the yin spirit to the appropriate place, it happens that the seal is lifted, and after the yin spirit is free, it will attack all the surrounding beings indiscriminately.

Although this method is easy to say, it also took a lot of time and blood for the Shadow Knife to gradually succeed.

Now the three jars that were chasing the blood of the Shadow Knife flew out of the window. At the same time, the shadow knife in the firewood room suddenly darkened his eyes, and his body was even more motionless, as silent as a dead man in an instant. The shadow knife forcibly suppressed his anger to the lowest at this time, and slowly hid his body into the shadow behind him, leaving only a vague shadow in this firewood room.

Not long after, there were three sudden sounds of porcelain jars breaking from outside, followed by a strong wind, and the originally calm environment outside was like a few drops of water dripping into a calm oil pot, and it boiled instantly. In an instant, in the feeling of the shadow knife, it seemed as if something terrible had happened outside. The devil cries wolf. The wind and clouds rose suddenly, mixed with some screams from time to time. Not only did the Yin spirits attached to the wall pounce out as if they had been stimulated by something, but even some of the Yin spirits hiding in the shadows also rushed out, roaring at each other and rushing towards the Yin spirits who had just been released from the porcelain jar.

It is said that the yin spirits in these porcelain jars are also really unlucky, after being imprisoned for a long time, countless grievances have accumulated in their hearts, and these grievances happen to be the energy that these yin spirits rely on to grow. You must know that between these yin spirits, in fact, they can gradually become stronger by devouring each other, and as long as this devouring starts to happen, it will not stop, unless only the last yin spirit is left, and if it is at that time, that yin spirit is a collection of all the energy of this group of yin spirits, and its body will become very strong accordingly, which is called yin evil, and its strength is comparable to that of a high-level martial artist who is proficient in illusion. This kind of scene of yin spirits devouring each other is not long to see, except that the number of yin spirits is very small, but also because this kind of final yin spirit is extremely destructive, usually causing a big disaster around, so as long as the yin evil appears, it will be exterminated by the warriors.
