Compared with the physical body, the function of the spiritual body is also very simple, so the ingredients are much simpler.

If you want to cultivate your spiritual body, you just need to ensure that your spiritual body can generate energy in your body.

There is no pressure on Kun Yu at this point.

In just a breath, the energy in the body began to wash through the spiritual body.

Like a sponge, the spirit body quickly absorbed the energy, and then passed quickly, still leaving an empty spirit body.

However, this time Kun Yu did not have any trouble.

The energy converged again and washed through the spirit body at a great speed.

Like taking a bath, the spiritual body is washed away by the energy over and over again at high speed.

I don't know how long it took, and a staring Kun Yu looked at it for a while.

A barely visible pitch-black particle appeared in the mental body.

Stopping the energy rush, Kun Yu seriously raised a large number of particles that appeared on the spirit body.

The particles were too small, and if Kun Yu hadn't determined that the composition of the spirit body was very simple, he would have wondered if it was the spirit body's own thing.

But it was this tiny black grain that was a major breakthrough for Kun Yu.

This particle is nothing else, the remnants of the formal energy that keeps washing away.

Originally, the spirit body cannot store energy, because the structure of the spirit body is a leak net.

But there are also meshes in the leaky net.

As the energy washed away rapidly, a little bit of energy was finally left because it couldn't pass through the mesh.

Kun Yu wanted the spiritual body to cultivate this particle, which was very important.

Not daring to move casually, Kun Yu carefully covered his spiritual power on the pitch-black particles.

After perceiving it for a long time, it was confirmed that this was the particle of energy residue.

With joy in his heart, he took a soft breath.

A tiny, sketched array appears on the surface of the particle.

This array was copied by Kun Yu from the turtle shell in his body.

I didn't understand why the turtle shell automatically absorbs energy before, but now that I have seen more, Kun Yu can also understand the lines engraved on the turtle shell.

It's just a not complicated concentrating array diagram.

Now the simplicity of this array appears on the particles, and the particles, as the driving energy of the array, begin to drive the array.

Kun Yu looked forward to it nervously.

The particles began to dissipate slowly, and soon Kun Yu was invisible to the naked eye.

But the feedback given by the spiritual power, this particle is still a little bit.

Just when Kun Yu thought that the experiment had failed, the spirit body suddenly felt uncontrollably slightly.

The energy surging around him suddenly stopped, and then a suction force emanated from the spiritual body.

The suction force is not very large, but the surrounding energy is rushing towards the spirit body like a bird's nest.

This is the first time that without Kun Yu's deliberate manipulation, energy has taken the initiative to surge into the spiritual body.

As energy enters the body, the particles that are almost dissipated begin to slowly expand.

A black dot visible to the naked eye appeared on the back of the spirit body's hand.

Soon, a thin black thread appeared from the black dot on the back of the hand.

The thin line begins to run upwards along the transparent arm.

A strong pain stimulated Kun Yu's soul.

For the first time, Kun Yu felt what it meant to be in pain to the depths of his soul.

Although he had been prepared for a long time, this sudden pain made Kun Yu unable to accept it for a while.

First the spirit body began to tremble, and then the whole body began to tremble.

Kun Yu lost his voice in a moment of pain, and his mouth grew like a fish out of water, his whole body was constricted, and he kept shaking.

The thin black line on the hand still extends steadily upward.

Gradually, the black line had crossed the elbow and began to climb towards the shoulder.

The energy of the whole body began to riot, and the violent energy tide kept impacting the spiritual body.

The spirit body that was already in the center of the vortex was no longer a stubborn stone in the river at this time, but a flat boat in the vast ocean.

The surging black energy lost Kun Yu's control, and kept crashing into the spirit body with the suction.

Kun Yu's eyes were pitch black, and his five senses disappeared completely.

This is the stress protection given by the body.

But even though he was about to lose consciousness in pain, Kun Yu still understood one thing.

If you lose consciousness, your whole body will be useless.

Clenching his teeth hard, Kun Yu closed his eyes tightly.

Strive to break through the blockade of the energy tide and try to connect with the physical body.

At this time, a thick black mist around Kun Yu's body was slowly forming.

Violent energy fluctuations are constantly erupting.

The crystal shrimp that was cultivating suddenly opened his eyes.

The strong frontal energy fluctuation made his heart tighten, and he subconsciously took a few steps backwards.

After seeing clearly that it was Kun Yu, he relaxed slightly.

The black fog that enveloped him became thicker and thicker, and a furious roar rose from the black mist.

The roar seemed painful, but more like an unconscious outburst.

The black mist gathered more and more, filling the entire cavern.

Standing in the black mist, the crystal shrimp's eyes began to glow red.

Anxiety gradually came up.

Finding that something was wrong with him, the crystal shrimp head ran out without looking back.

Another roar rang out, and the black mist began to shrink.

Soon, behind Kun Yu, a fierce beast formed by a black mist suddenly opened its eyes.

The blood-red light flickered, and the eyes full of spirit looked around.

Then he looked at Kun Yu, who was sitting cross-legged on the ground, trembling constantly.

With a fierce glint in his eyes, he opened his huge mouth, ready to swallow Kun Yu in one gulp.

Suddenly, Kun Yu, who was trembling, stabilized his figure.

A hand was raised automatically.

A dark light lit up on the tip of his finger and hit the forehead of the beast that was rushing towards him.

Like a wild beast howling, the bloodthirsty beast suddenly stopped its body and opened its mouth to howl miserably.

Then it turned into black smoke with a thud and dissipated into the air.

The thick black smoke returned to his body, and his frantically trembling eyelids slowly calmed down.

Calm was restored in the cave.

The spiritual body in the body also stopped trembling at this time.

Kun Yu slowly withdrew his hand, and the surrounding flood-like energy finally stabilized.

Holding back the pain, Kun Yu gasped sharply.

The sense of crisis that lingered in my heart finally dissipated.

Not knowing what's going on out there though.

But Kun Yu in his body was almost devoured by his own energy just now.

For the first time, the uncontrollable dark energy showed Kun Yu its might.

He had never seen such a terrifying majesty, which made Kun Yu think that he would die.

Fortunately, at the last moment, I still reached a connection with the body.

With a long breath, Kun Yu frowned tightly and looked at the thin black thread that had been derived to his neck.

As the thin line continued to move, Kun Yu snorted from time to time.

But with preparation, Kun Yu held on, constantly diverting his attention, trying to think of other things to distract from the pain.

Now he has a wonderful balance with the energy in his body.

Once this balance is broken, a more ferocious backlash awaits it.

The pain was so severe that the mind could no longer function properly.

Kun Yu can only let his thoughts wander freely, thinking about whatever comes to mind.

Unbridled imagination drifted through my mind, and finally returned to the present.

The thin thread that spread throughout the neck continued upwards, along the transparent face of the spirit body, to the brain.

Another wave of intense pain.

Kun Yu suddenly lowered his head and coughed vigorously.

But there was nothing else in the spiritual body except energy, and Kun Yu coughed desperately but still didn't cough up anything.

The mind began to dissipate again, and the eyes began to be cloudy again.

Like an ordinary person who hadn't slept for months, Kun Yu's eyes narrowed.

Endless exhaustion and pain urged him to fall into a deep sleep as soon as possible.

The energy that had just stabilized around him was surging again.

Blinking vigorously, Kun Yu forcibly widened.

The thin thread is coiled in the head into a disc.

Soon, four thin lines were scattered in the disc.

At the same time, it goes to all parts of the body.

The pain doubled again.

Kun Yu, who was already numb to pain, was hurt again.

The eyes bulge deeply.

The tongue thrust out forcefully, and the arms and limbs trembled uncontrollably.

The muscles of the whole body are like earthworm versions rolling up and down.

The face has been distorted.

It was dark in front of him, and Kun Yu was blind.

Perception was blocked, and Kun Yu was completely plunged into endless darkness.

In a daze, Kun Yu wanted to stand up.

But they don't feel the presence of hands and feet.

I tried to twist my neck, but there was still no response.

Knowing that this should be the self-protection of the spirit body, Kun Yu had no choice.

The energy in his body began to boil uneasily again.

The dark aura began to collide with the distorted and deformed spirit body.

The thin black threads traveled towards the whole body at an extremely fast speed, as if they were comparing the speed with the dark energy of the riot.

In the cavern, the dissipated black fog reappeared.

The crystal shrimp who had just returned wailed, turned around and ran out again.

The beast's roar was heard again.

Only this time, there was more than one roar.

Kun Yu's body also began to twist and deform, his muscles spasmed, and his bones were so fragile that they seemed to shatter at the touch of a touch.

Two beasts poked out of the black mist.

Scarlet eyes stared at Kun Yu tightly.

A bloodthirsty aura enveloped the entire cavern.

The two evil beasts made a hole in the air restlessly, and their smart eyes stared at Kun Yu without blinking.

After waiting for a long time to confirm that Kun Yu would not wake up again, the two evil beasts raised their heads and roared.

Flying in the air, the big black mouth opened to the limit.

The tone wrapped around Kun Yu's neck and waist, and the eyes of the two evil beasts flashed with excitement, and they bit down hard at the same time.

The expected bite did not appear.

A pair of hands grasped the closed mouths of the two beasts.

The vertical eyes on Kun Yu's forehead opened, and a terrifying light was released from his cold eyes.

The two beasts whimpered as if they had met a natural predator, and struggled desperately backwards.

There was a suction in the one-eye.

The two beasts didn't even scream, and then disappeared into the one eye.

His eyes closed, and his surroundings returned to calm.

The irritable energy in Kun Yu's body quieted down for a moment.

All energy stood still, motionless, as if time had stood still.

The thin black line on the spirit body sped up again.

The entire spirit body was already mostly wrapped in thin black threads.

A complete loop is about to be completed.

And all this, Kun Yu, who lost consciousness, did not know.
