"Kid, what is your martial spirit? In our Aolai City Spirit Tower, there are a total of seventy-three white souls to choose from, and I will help you choose a relatively suitable soul according to your martial soul. ”

Looking at Yao Xuan, the spirit master explained lightly.

"Master Spirit, my martial soul is a dragon."

Hearing the spirit master's question, Yao Xuan also replied immediately.

"Lizards? This is a relatively powerful beast martial spirit! Since your martial soul is a dragon, choose the soul of the ten-year Black Rock Snake, the snake can be regarded as having a certain connection with the dragon, so it will be more compatible with your martial soul. ”

Hearing Yao Xuan's answer, the spirit transmitter thought for a moment, and then suggested.

"Thank you for the suggestion! Then I'll choose the Black Rock Serpent as my soul. ”

After receiving the advice of the spirit transmitter, Yao Xuan also replied without thinking.

For Yao Xuan, the soul that is fused now does not have much significance, it is just for the purpose of advancing the soul master, and as long as the soul master is advanced, Yao Xuan can receive the system reward, and replace the original soul with the infinite growth soul, therefore, Yao Xuan also simply accepted the advice of the soul transmitter.

"Okay, then you can come with me."

As he spoke, the spirit transmitter led the way in front and led Yao Xuan to another room in the opposite corner.

Compared to the previous psychic power testing room, the area of this room is much larger, and in the middle of the room, there is a cylindrical instrument with a height of five meters and a radius of about three meters, similar in appearance to a large cultivation tank on the earth.

The interior of the instrument is filled with a viscous green liquid, and in addition to this, there are many transparent spheres with a diameter of about thirty centimeters suspended inside the instrument, each emitting a faint glow.

Walking up to the device, the teleporter pressed several buttons as well, and immediately after, a white orb of souls fell from the exit of the machine and fell into the metal box below.

"Press this button and you'll be able to release your soul. After the research of our Spirit Transmission Tower, the soul master will release the soul with his own hands, and the degree of integration between the soul and the soul master is higher, so this process must be carried out by you personally. ”

Picked up the soul ball and placed it on top of an oval instrument next to it, and then the spirit transmitter also ordered Yao Xuan to come to the side of the instrument.

"I see, Soul Herald."

Listening to the spirit transmitter's words, Yao Xuan also nodded, then walked to the side of the instrument, reached out and pressed the button.

With Yao Xuan's movements, a soft yellow light emitted from that instrument, which fell on the soul spirit ball, and immediately, the surface of the soul spirit ball also emitted a faint light, and the surface of the originally sealed sphere gradually became transparent, exuding a faint breath of life.

A faint white light flickered, and in an instant, the entire soul ball slowly opened from the middle, and in the center of the soul ball, a snake-shaped soul with a length of about sixty centimeters, a diameter similar to an adult's wrist, and a body with black scales, shrunk into a ball.

"Come, this is your soul, the Black Rock Serpent of ten years. Now, as long as you're ready, you can officially fuse it and advance to the Soul Master. ”

Looking at the serpentine soul, the spirit transmitter also opened his mouth to explain.

"Well, I'm ready."

Hearing the words of the spirit transmitter, Yao Xuan nodded, and then said firmly, for him, fusing a ten-year soul is not a problem at all.

"Okay, then come with me. For soul masters who purchase souls in the Spirit Transmission Tower, we will provide a special training room to help them smoothly fuse souls and complete their promotion. ”

Seeing that Yao Xuan was ready, the spirit transmitter also explained, and then led Yao Xuan to a cultivation room.

This is a cultivation room with an area of twenty cubic meters, and around the cultivation room, there are many soul guide arrays, and it is obvious that these magic circles should be soul gathering arrays.

Yao Xuan walked into the cultivation room, approaching, and the soul guide magic array in the cultivation room also lit up one after another, and suddenly, Yao Xuan felt that the concentration of soul power in the cultivation room suddenly increased, and at the same time, a faint fragrance came from nowhere, which made Yao Xuan feel refreshed.

"Let's get started."

Sitting quietly on the ground, Yao Xuan also put the original soul ball on the ground, and then sat cross-legged, held his breath, eliminated distracting thoughts in his heart, and put his right hand into the soul ball.

For low-level souls, they had no substance, just an illusory form, but Yao Xuan still felt that he had touched something warm.

As soon as his mind moved, in front of Yao Xuan's body, the nine-colored light suddenly converged, and the ancestral dragon martial soul suddenly appeared, and at this moment, the black rock snake soul that was still alive suddenly shook its body, its eyes flashed with terrified brilliance, and its energetic body instantly curled up into a ball.

"Give me fusion!"

As soon as his mind moved, the ancestral dragon martial soul in front of Yao Xuan rushed towards the soul spirit ball, and immediately opened his mouth, and with a slight inhalation, the black rock snake soul instantly shrank, and was sucked into the ancestral dragon martial soul.

As the Black Rock Snake Soul was absorbed by the Ancestral Dragon Martial Soul, the process of soul fusion officially began, and Yao Xuan closed his eyes and began to fuse his soul according to the method taught in the school.

With the beginning of soul fusion, the soul power fluctuations in Yao Xuan's body also began to become violent, and the soul power in his whole body boiled and rushed out, like a wave, impacting the bottleneck of the soul master realm.

With the impact of waves of soul power, cracks quickly appeared on the bottleneck that bound Yao Xuan, and when they were close to those cracks, they expanded into cracks, and finally with a crisp "click", they were completely broken.

At this moment, Yao Xuan also suddenly felt that his whole body was light, and immediately, a huge suction force suddenly appeared in his dantian, sucking the soul power in the room frantically towards his body, and through his meridians, surging towards his dantian.

At the same time, Yao Xuan also felt that his vertebrae suddenly heated up, and streams of incomparably hot heat gushed out from the depths of his body, and followed his veins, surging wildly towards all parts of his body.

If Yao Xuan could look at himself at this time, he would be surprised to find that inside his body, streams of nine-colored strange energy were spreading, forming an extremely complex, mysterious, and nine-colored grid in his body, containing the breath of the Great Dao.

And every time those grids passed, the cells in Yao Xuan's body were frantically absorbing this nine-colored energy, undergoing the deepest transformation, making a leap in the level of life, and the breath became deeper and more powerful.
