After Xu Shu got this soul box, he opened it and saw that it contained four soul balls of different sizes, and the soul ball that he had taken out to test the strength of his soul power was the smallest of them.

The other three correspond to the three levels of soul balls of night travel, day travel, and ghosts.

The four soul balls, corresponding to the four yin soul levels, were not imagined by Xu Shu.

Because in addition to this soul ball, there is also a booklet in the soul box, which not only records some soul control techniques, but also lists the use of soul balls.

At that moment, Xu Shu sat cross-legged and threw the Night Wandering Soul Ball into the air, seeing the Night Wandering Soul Ball falling rapidly, a heat passed through his eyebrows, and with a whoosh, the rapidly falling Soul Ball was firmly supported by the Soul Thought.

As soon as Xu Shu's mind moved, the Night Wandering Soul Ball fell back into the soul box accurately.

Immediately afterwards, Xu Shu threw out the Sun Tour Soul Ball, the soul thought was released, and the Day Tour Spirit Ball was also caught.

Xu Shu breathed a sigh of relief in his heart, and broke through the daily tour in one fell swoop, which was his biggest ambition to settle in the Great Zhou Tower this time.

After spending this amount of resources, with this result, Xu Shu finally had an explanation for himself.

Suddenly, his eyes flickered and he stared at the soul ball the size of a pomegranate.

Immediately, he held the soul ball tightly and threw it violently.

With a bang, the soul ball fell to the ground, and the soul thought was not supported.

The obvious failure not only did not discourage Xu Shu, but made his heart splash with joy.

He threw the soul ball again, and the soul thought followed, and with a snap, the soul ball smashed to the ground again.

But this time, the sound of the soul ball landing on the ground was obviously much lighter.

It turns out that there is a clear understanding in the soul control technique, if the yin soul does not reach the ghost demon, it will never have any effect on the ghost and demon-level soul ball.

The first time Xu Shu threw the ghost soul ball, he clearly felt that the soul thought had a lifting power on the ghost spirit ball.

Although the ghost soul ball still fell to the ground, in Xu Shu's opinion, this was just the reason why his soul control technique was still in the rusty stage.

At that moment, he sat cross-legged on the ground and began to throw the ghost-level soul ball again and again, until the sound of the third watch came in the middle of the night, and Xu Shu finally held the soul ball firmly for the first time.

"Demons!"

Xu Shu was so excited that he wanted to cry.

At the moment when the source wheel was shattered, he needed such exciting news so much.

With a swish, his yin soul escaped out of the yin orifice, and suddenly almost turned into a cloud of phantoms, Xu Shu urged the soul control technique, and the phantom slowly solidified, turning into an almost condensed entity.

His soul thoughts were released, and four soul balls flew up with a whizz, spinning around his soul body at high speed.

The yin soul was separated from the body, freed from the shackles of the body, and Xu Shu controlled the soul ball again, which was like a finger.

I saw that his Yin Soul's hands were slightly closed, and the four soul balls seemed to be placed under the hydraulic press and slowly flattened.

Xu Shu's Yin Soul shook his head slightly, and suddenly, four phantom shadows separated from his Yin Soul, each holding a flattened soul ball.

After more than thirty breaths, the four phantoms escaped back to the Yin Soul Body.

The four soul balls have turned into four soul swords of different lengths, the short soul sword is only one foot long, and the long soul sword is more than three feet.

Xu Shu's Yin Soul made a big move, and the longest soul sword swooped back into his palm, and he saw a cloud of blue flames coming out of Xu Shu's palm.

This dark blue flame is nothing else, it is the unique sign of cultivating into a ghost, the soul fire.

The soul sword was only in the center of the soul fire, and it trembled at a high speed, and after half a pillar of incense, the soul sword obviously lost a lot of weight, the color became pure white, and the blade was very sharp.

Xu Shu flicked his fingers lightly, and the large soul sword array was behind him, and immediately, he moved another soul sword and continued to refine it.

More than an hour later, the four soul swords all turned into pure white, surrounding Xu Shu's body, and the sword body of each soul sword was engraved with inscriptions.

According to the size of the sword body, they are: Qinglong, White Tiger, Vermilion Bird, and Xuanwu.

Using the four divine beasts that guarded all sides as the name of the sword, it undoubtedly also showed Xu Shu's expectations for the four swords: to protect the Yin Soul Body.

Xu Shu received the four soul swords, and the condensed yin soul was a little weak, obviously, the soul fire sword training caused a lot of loss to Xu Shu.

But it is his ghost that makes a ghost, and in his eyes, this world has simply undergone earth-shaking changes, and nothing has not been new, and nothing has stimulated his desire to explore.

With a swish, his Yin Soul took the Green Ring, soared into the sky, flew higher and higher, and soon, he was above the clouds, and the violent air convection hit, and the Yin Spirit was blown into the shape of a man almost unable to maintain its human shape.

Although he was torn by the pain and danger, Xu Shu felt very happy, as if he had attained the Tao and vowed to soar.

His Yin Soul continued to soar into the air, not knowing how high it flew out, until the Yin Soul was in a purple world, and Xu Shu suddenly sounded an alarm.

In the next moment, the purple sea rolled, and countless muffled sounds came from afar, becoming more and more intense.

"Yunlei Hometown!"

Xu Shu suddenly thought of a word in the soul control technique, and he was almost shocked, and at the moment, he couldn't care about anything else, and desperately stabbed down.

His soul fled extremely fast, but the muffled thunder was getting closer and closer, and the sound was getting louder and louder, and suddenly, the sound of rolling thunder came from above, and a blazing yang fire turned into a giant hand that split the sky, grabbing his soul.

Xu Shu has no remorse, he has practiced soul arts, he knows too well the thunder method, what a terrifying deterrent to the yin soul, not to mention, the hometown of cloud and thunder above the nine heavens, this is almost the birthplace of the legendary thunder tribulation.

He is just a ghost, he can barely listen to the thunder, where can he withstand the interception of clouds and thunder.

Seeing that the big red hand had been caught in the air, Xu Shu's heart was full of despair, and he was even ready to return to silence, suddenly, the thought flashed, and with a whoosh, he aimed the green ring at the red big hand and sprayed out.

At this point, he has no other way but to be a dead horse and a live horse doctor, hoping that this miraculous green ring will show its power again.

To Xu Shu's delight, the green ring shot out towards the big red hand, and the big red hand that came quickly froze in the air, and his ghost accelerated away, and after a few breaths, he finally no longer felt the terrifying thunder killing intent.

At the same time, his soul thoughts began to be released in full force.

Suddenly, with his yin soul as the center, within a thousand zhang, they were all in the sense.

After more than ten breaths, he felt the presence of the Green Ring, and the Yin Soul shot out, and once again captured the Green Ring.

He gently rubbed the green ring, and the baby was endless.

Unconsciously, a ray of red light shot in, and in an instant, ten thousand golden lights almost pierced Xu Shu's Yin Soul Hole.

It turned out that the sky would be bright and the sun would rise in the east.

Although, Xu Shu has become a ghost and is not afraid of the sun.

But the bright sun really shot on his body, which still made him feel uncomfortable.

At that moment, he captured the yin spirit, almost falling downward, and after dozens of breaths, the yin soul returned to its main body, raised his eyes to look at the sky, and the east was already flushed with a touch of fish belly white.

Thinking of the release of the soul of the right talent, Xu Shu couldn't help but be curious.

At that moment, he released his soul thoughts from the center of his eyebrows, up and down, left and right, about a hundred zhang away, all in the sense.

Of course, there is a door wall to obstruct it, and his soul cannot penetrate it.

Even so, he was overjoyed.
