These black winds were mixed with a gloomy aura, whirring and whistling, but they only blew in the school grounds, and gradually subsided as soon as they reached the walls and doors.

Looking at the several layouts of the school field, it is the popular method more than a thousand years ago, and this kind of black wind, Lu Feng also remembered a popular layout of the school field in the past.

The school field is used to compete and practice martial arts, and to practice techniques other than exercises. The exercises are based on the techniques, and the techniques are the means to assist the enemy in attacking the enemy and improve the utilization rate of the exercises.

But since that catastrophe more than a thousand years ago, many exercises have not been lost, and the techniques are almost non-existent.

The current means of attack are all new techniques that have been rediscovered, and the previous inheritance has lost its soil.

Even the means of building a school field to exercise techniques are no longer cared for, after all, without the inheritance of techniques, it is useless to build a school field.

Lu Feng still read a relatively remote book to know the doorway inside.

These black winds should be something that Yin Soul needs to practice some kind of evasion technique, and it is conditionally stimulated.

And the remnant souls all over the school field are likely to be swept away by these black winds when they contact this evasion technique, and their souls will be incomplete.

This Yin-Yang Road Judgment Mansion has been abandoned since the Great Tribulation of more than a thousand years, so it is likely that these remnant souls in it have existed for more than a thousand years.

The five ghosts were still trembling in Lu Feng's body: "This place is simply perverted, ghost nemesis, master, don't come to this kind of place next time." "The wood ghost is the only one of the five ghosts who is full of vitality, and in the face of all the dead black winds, he is the one who is most disgusted and afraid.

"Sir, don't bring us to this kind of place." The Soil Ghost also chimed in.

"As a weapon, you have no say." Lu Feng waved his hand and no longer paid attention to the complaints of the five ghosts.

However, the ghost king fetus, which has been stable in the yin and yang jade seeds, has changed, and the supply of nutrients that need to feed the ghost fetus has stopped, and the development of the ghost king fetus has also been frozen.

But after entering the Yin Yang Road Judgment Mansion, the surroundings have always been pure Yin Qi. Although the Yin and Yang Road Judgment Mansion is an underworld institution set up in the yang world, this kind of mansion adopts yin veins and formations after construction, so that the environment in the mansion is as close as possible to the underworld, and provides a steady stream of pure yin qi for the Yin soldiers and Yin officials of the Lu Judgment Mansion.

The jade seed, which had always been balanced by yin and yang, was also affected, resulting in an imbalance of yin and yang within it, and the continuous flow of spiritual energy had been negative.

There was a dry umbilical cord on the navel of the ghost king's fetus, and it turned rosy under the nourishment of these pure feminine spirits.

And there is a faint spiritual opportunity circulating and spitting on the umbilical cord, the nose of the ghost king's fetus twitches, the eyelids vibrate, and there is a tendency to open the eyes.

And now the evil qi in the black wind is extremely fierce, and it can take away the three souls and seven spirits in the human body if it blows, but it is the evil qi that the ghost king's fetus urgently needs.

Condensing the aggregate, alchemy returning to the source, these two sentences are the mantra of the ghost king's fetus. The ghost king fetus is not an ordinary ghost thing, it is born with a dantian, and the phrase alchemy returning to the yuan does not refer to refining the medicine pill, but refining the dantian.

After birth, the ghost king fetus can cultivate on its own, and has its own set of cultivation methods.

Now that he has encountered such a strong and fierce yin and evil aura, it has condensed into a black wind, and the ghost king fetus uses both hands and feet, and wants to climb out of the yin and yang jade seeds.

The fetal-sized ghost king was white and tender and blue all over his body, and after raising it in the jade seeds for so long, he was moistened by the spirit and eliminated a lot of blue and black color. Now it looks like it's the size of a baby as a little white.

Lu Feng hadn't noticed the movement in the yin-yang jade seed on his wrist for the time being, and only used all his energy to recall the book he had read before.

"The Construction of the Soul Master's School" talked about the underworld school, and he remembered that this kind of school was a cruel selection base.

This is the place where Yin soldiers are selected, and the Yin Spirits who have been recruited learn the techniques and then inspect the school field. If you pass the inspection, you will become a yin soldier, and if you don't pass the inspection, you will be sent back. And those who are unlucky and swept away by the black wind have become these remnants in the school field now.

But when it comes to cruelty, the proportion of yin souls that are swept up by the black wind because of bad luck is more than two hundred times that of those souls that are still intact after failure.

After recalling, Lu Feng took a sharp breath, fortunately, don't test me in this school field.

It wasn't difficult for him to get through this room now, as long as he leaned against the wall, these black winds would naturally die out and would not harm him.

After all, it is a failure to get out of the school field, and being forced to the root of the wall is also considered a failure, but most people are swept away by the black wind before they reach the root of the wall.

Lu Feng planned to go back and change the stop mark outside to a triangular traffic marker.

Suddenly, he felt a tightness in his back, his fur exploded, and a dangerous cold aura made his whole body stiffen.

It's a powerful coercion, it's not mental pressure, it's a kind of signal transmission.

"Turn around and leave, die!"

Lu Feng felt that as long as he turned around, he would die immediately, which was the feeling given to him by his body's own sixth sense.

"The 168,320th place in the Yin Soldier Assessment, name?"

Lu Feng stopped when he wanted to step out of the gate, but he didn't expect that before he could turn around, a voice asked him in ghost words.

Lu Feng turned around and saw that three sturdy stone statues with big shoulders and round waists appeared on the steps in front of him.

The stone statues on both sides wore high hats, holding soul nails and soul hooking whips, one with a bull's nose and a horse's face.

The stone statue in the middle holds a pen and holds a book, which is very similar to the legendary judge's pen and the book of life and death.

A drop of cold sweat dripped from Lu Feng's forehead, what the hell is going on? It's been more than a thousand years, and this school is still functioning?

"Of the 168,320 Yin soldiers to be chosen, what is your surname? If you don't report it quickly, you will delay the selection of soldiers, and carefully sentence you to eighteen layers of hell reincarnation. ”

The high hat of the bull's nose flicked the soul whip, Lu Feng quickly jumped over, this stone statue can actually move, this is not a simple stone statue, it is likely to be a stone puppet.

The underworld didn't know where to go, and there were eighteen layers of hell reincarnation, so of course Lu Feng didn't think about it in his heart.

But the feeling of crisis just now he also understood in his heart that the strength of these three stone statues was too strong. I'm afraid it's either blue or blue.

"I'm not a ghost, I'm just passing by." Lu Feng laughed dryly, he was purely playing soy sauce, and this Yin soldier assessment was about his wool business.

"You have the Soul Crossing Card, and you are the Soul Crossing Messenger who acts on behalf of the underworld in the Yang Realm. Yin bone and yin flesh are also a member of the underworld, and they are qualified to assess and select Yin soldiers. The stone statue with the judge's pen explained kindly.

Let Lu Feng stay on the spot, the soul card? It doesn't mean the Soul Crossing Chart.

Lu Feng took out his Soul Crossing Magic Plate and said, "Is this the Soul Crossing Card?" ”

"That's right, Soul Crossing Messenger, quickly report your name and conduct an assessment."

"I didn't sign up, so I just passed by here and didn't need to take the test." Lu Feng put the Soul Crossing Method Plate in his pocket. Master, Master, you can hurt people, how can this thing have anything to do with the underworld.
