Biyuan Shuanghua Divine Liquid cannot be given directly to spiritual insects, and requires the assistance of the master to refine it.

Qin Sang made a seal, and the divine liquid exploded into a cloud of mist, surrounding Tianmu Butterfly.

The mist is hazy, and the Sky Eye Butterfly flaps its wings gently, causing ripples. The divine liquid adheres to the butterfly wings, gradually seeps in, and is absorbed and refined by the Sky Eye Butterfly.

Qin Sang sat cross-legged on the sea, staring at the Tianmu Butterfly.

Refining Biyuan Shuanghua Divine Liquid and clearing the level are carried out at the same time.

At this time, the Tianmu butterfly has begun to hit the bottleneck, and its wings are trembling slightly, which is becoming more and more obvious.

Qin Sang sensed that Tianmudie was going through the pain of breaking through the barrier, so he could only gently comfort her and use the secret techniques in the "Panhu Sutra" to help Tianmudie stabilize its foundation.

The fog is getting thinner.

The breath of the Sky Eye Butterfly undulates violently, its wings tightly wrap its body into a ball, like a cocoon, and the patterns on its wings become increasingly bright.

"Want to turn into a cocoon?"

Qin Sang's heart moved.

According to common sense, when a spirit insect breaks through, it will go through a process of transformation into a cocoon. When it transforms into a cocoon, the spirit insect sleeps for a long or short time, which is the most vulnerable stage of the spirit insect.

To subdue spirit insects, this time is often chosen to have the highest chance of success.

The Celestial Eye Butterfly will also transform into a cocoon when it first metamorphoses, but when it breaks through the fourth and fifth transformations, due to special circumstances, it does not transform into a cocoon, sleep, and break out of the cocoon step by step like ordinary spiritual insects.

There was no external interference this time, but Qin Sang was not sure whether the Tianmu butterfly would turn into a cocoon.

Moreover, when the spirit insect reaches the sixth transformation, which is equivalent to the level of the Void Refining Stage, it will definitely undergo earth-shaking changes, and previous experiences may not be applicable.

At this time, Qin Sang noticed a glimmer of light emerging from the Tianmu Butterfly, emitting strange fluctuations.

The shimmer seems to be composed of countless extremely fine light filaments. The light filaments are like soft fluff, gently swinging.

Under low light, the patterns on the butterfly's body become more colorful. There is a transparent membrane that isolates the butterfly from the outside world, forming a cocoon of light.

"I'm really going to turn into a cocoon. I'm afraid I'll have to sleep for a long time after turning into a cocoon..."

Qin Sang thought to himself that transforming into a cocoon and sleeping is the process of transformation of a spiritual insect. The moment of breaking out of the cocoon is also the last moment of transformation. At the same time, the natural disaster will come. This time, the trip was in vain.

Just as Qin Sang was thinking to himself, he suddenly felt something strange.

'Whoa!'

Without any warning, the wings tightly hugged by the Sky Eye Butterfly suddenly vibrated violently, and ripples appeared on the light cocoon.

Qin Sang's expression changed instantly.

Immediately afterwards, the situation took a turn for the worse. The Celestial Eye Butterfly's wings trembled uneasily, as if there was a huge force trying to open the closed wings, and the Celestial Eye Butterfly was desperately resisting.

Once the wings open and the light cocoon breaks, it means the breakthrough fails.

Unexpectedly, something unexpected would happen at this time. Qin Sang's expression changed several times. Miraculous medicine was rare, and the opportunity for breakthrough was fleeting. If he failed this time, he wouldn't know how long he would have to wait next time.

Sure enough, nothing is foolproof in this world, let alone the spirit insect breaking through the sixth transformation. Even if he is already a Void Refining cultivator, he cannot guarantee success.

Maybe Tianmu Die can get through this on his own, but he really has to wait until the last minute. If it fails, it will be too late for Qin Sang to intervene.

Qin Sang no longer hesitated and decisively forced out his blood essence.

‘Bang!’

Like the previous Biyuan Shuanghua Divine Liquid, the essence and blood exploded into blood mist, directly seeping into the Tianmu Butterfly's body.

When cultivating natal insect Gu, the witch clan must feed it with essence and blood, but such a crude method should be avoided as much as possible. On the one hand, it may make the spirit insect become ferocious and backfire on the owner; on the other hand, it may also affect the foundation of the spirit insect.

It can be said that there are many hidden dangers, and various secret techniques must be used for every feeding.

Qin Sang had always been very cautious before, and this time he had to do it out of necessity. However, it was only this once, and he would hopefully make up for it by putting more thought into it in the future.

Which is light or heavy, Qin Sang will weigh it himself.

Regardless of himself, he continuously forced out drops of the purest blood essence, which turned into layers of blood mist and was swallowed by the Tianmu Butterfly.

The eyes on the wings shine with blood and are filled with bloodshot eyes. Their gazes are penetrating and fierce, like the path of a fallen demon.

Qin Sang did not dare to relax for a moment, and tried his best to control it in the most subtle way according to the changes in Tianmu Butterfly's state.

After swallowing Qin Sang's blood essence, the aura of the Heavenly Eye Butterfly changed again, its wings stopped trembling, the light cocoon gradually calmed down, and the blood glow in the Heavenly Eye gradually faded away.

Seeing that the light cocoon is getting thicker and thicker, and the condition of Tianmu Butterfly has stabilized, Qin Sang's face is full of exhaustion, and he is about to stop, but unexpectedly the mutation reappears!

‘Bah!’

The light cocoon actually tore a crack.

Qin Sang was shocked, and immediately realized that there was nothing wrong with Tianmu Butterfly. The light cocoon was torn open by Tianmu Butterfly on its own initiative.

The light cocoon has been formed, but the Heavenly Eye Butterfly did not enter a deep sleep, but tore the light cocoon open!

At the same time, Qin Sang felt the extremely urgent thoughts coming from Tianmu Die. She wanted to go out to find something. This thing was what she needed urgently and she was not willing to wait for a moment.

Qin Sang knew in her heart that what she needed was Jie Lei!

'Snapped!'

The light cocoon cracked open again, and a foot stretched out, grabbed the light cocoon, and pulled hard.

‘Bah!’

The light cocoon burst on the spot, and the extremely gorgeous butterfly wings suddenly burst out, revealing a light and elegant swallowtail butterfly. Every pattern was so perfect, like the most beautiful elf in the world.

'Huhuhu...'

The wind was strong and the sky was covered with dark clouds.

Day turns into night.

Dark clouds rolled, thunder snakes danced wildly, the power of God descended on this sea area, and a terrible storm was born.

Perhaps it was driven by Tianmu Butterfly's urgent thoughts, or perhaps Qin Sang's essence and blood had an effect. Similar to when he swallowed Qingluan's essence and blood and broke through the fourth transformation, in a short cocoon process, Tianmu Butterfly reached the stage of transformation in an instant.

The last step will lead to disaster!

Everything that happened today was so unexpected that Qin Sang was caught off guard. Fortunately, he did not react slowly. Regardless of his own weakness, he immediately mobilized the vitality of heaven and earth to seal off the sea area to prevent the leakage of Qi.

The calamity thunder was still brewing, and the Heavenly Eye Butterfly couldn't wait any longer. It flapped its butterfly wings and took the initiative to fly towards the calamity cloud.

Facing the dangerous calamity cloud, a fragile butterfly rushed forward without hesitation.

'boom!'

‘Crack!’

The thunderbolts met above Tianmudie's head and turned into a thunder dragon, swooping down with the aura of destroying everything.

The Heavenly Eye Butterfly showed no fear. With a flash of its Heavenly Eye, it shot out two blue thunders, facing each other tit for tat, and tried to assimilate and devour the Tribulation Thunder.

Qin Sang had seen this scene before in the world of talismans.

He looked at the calamity cloud and found that the first calamity thunder struck down, but the calamity cloud did not disappear.

After the monks entered the Void Refining Period, the four-nine heavenly tribulations became the sixty-nine heavenly tribulations, and the spiritual worm's heavenly tribulation also changed, no longer a tribulation thunder.

The first tribulation thunder passed by and either turned into lightning and escaped, or was assimilated into the tribulation thunder and was swallowed by the Heavenly Eye Butterfly.

Then the second, the third...

Later, this sea area was completely filled with thunder and lightning, and countless arcs flashed continuously. It was impossible to tell whether it was the tribulation thunder from the sky or the real thunder of the Tianmu Butterfly.

In the sea of ​​thunder, Tianmu Butterfly was chased by the tribulation thunder. Its figure appeared and disappeared, elusive, as if it was constantly flashing, dodging and resisting the tribulation thunder, while constantly swallowing the surrounding lightning.

Seeing this scene, Qin Sang's expression changed. Just as he was about to take a closer look, he discovered that there was another change in the robbery cloud.

All the lightning converged into one force and struck down with a bang.

"Spiritual insects transform into six heavenly tribulations, transforming into nine tribulations at once," Qin Sang has been counting the tribulation thunders silently, and the last one is the ninth tribulation thunder.

The heavenly calamity suffered by spirit insects is still not as good as that of monks, but for spirit insects, it is still a narrow escape from death.

However, Tianmu Butterfly does not look like it will escape death.

Facing the ninth tribulation thunder, Tianmudie sensed the danger and finally curled up.

As the tribulation thunder struck, the lightning accumulated on the surface of Tianmu Butterfly's body, and obvious signs of demarcation appeared at the edges, which were transformed by the clutching divine light. However, the tribulation thunder in the sixth transformation was not so easy to resolve.

The violent thunder engulfed Tianmu Butterfly, as if sealing her in a thick bolt of lightning, destroying her crazily.

After a brief stalemate, a brilliant brilliance suddenly appeared in the thunder. Immediately, a smart butterfly spread its wings and flashed in the lightning. In the blink of an eye, it penetrated the lightning, broke through the thunder, and flew into the sky.

Before the calamity clouds completely dispersed, the Heaven-Eyed Butterflies rushed into the calamity clouds, like wolves rushing into a flock of sheep, hunting for the calamity thunder scattered in the calamity clouds.

Seeing this scene, Qin Sang's eyelids twitched. Even if the power of the spiritual worm's calamity was weak, this move was really shocking.

The Heavenly Tribulation, which has reached the end of its power, can no longer threaten the Heavenly Eye Butterfly. The Heavenly Eye Butterfly flies up and down, devouring the Tribulation Thunder to its heart's content, like a happy child.

‘Whoosh!’

Tianmudie threw herself into Qin Sang's arms, grabbed his front tightly, and stared at Qin Sang with her big watery eyes.

In addition to the celestial eye on its back, the celestial eye butterfly also has eyes, which are smart and intimate, shining with the light of wisdom.

Her intelligence has been opened, but she still cannot truly transform.
