Zi Luolin looked at Cheng Fei, her eyes filled with confusion.
Cheng Fei did not know that the zhenqi he had unintentionally used had caused Zi Luolin to be shocked, but Cheng Fei had used quite a bit of his Innate Qi in front of Zi Luolin, so he did not mind there being another type of Innate Qi.
The Thunderbolt Tree formed in mid air, standing right in front of the Tetra-winged Golden Silkworm.
"Winding Lightning!"
The Thunderbolt Tree that Cheng Fei used was different from what he used. Because it was used against Tetra-winged Golden Silkworm that had Innate Qi penetrating, Cheng Fei intentionally strengthened the branches of the Thunderbolt Tree, making it more flexible.
After all, Cheng Fei did not want to kill the Tetra-winged Golden Silkworm, but wanted to capture and tame it for his own use!
The Tetra-winged Golden Silkworm rushed over, Cheng Fei controlled the Thunderbolt Tree, and it flew in all directions, enveloping the entire Tetra-winged Golden Silkworm.
Chirp! Chirp! Chirp!
The Tetra-winged Golden Silkworm channeled its penetrating force through the thunder vines that were drawing towards it. The branches that filled the sky could not trap it at all.
But how could Cheng Fei's methods be so simple?
"The zhenqi is the most berserk, the Tetra-winged Golden Silkworm uses True Qi to penetrate the Thunderbolt Tree's attack. Although it is always successful, the consumption of Tetra-winged Golden Silkworm is also extremely great." Cheng Fei's lips curled up into a smile, the Tetra-winged Golden Silkworm did not know that it had fallen into Cheng Fei's trap.
The Tetra-winged Golden Silkworm's penetrating ability was not limitless, it would eventually run out of energy. Although it could not trap the Tetra-winged Golden Silkworm, it could slow it down. On the other hand, Cheng Fei had less energy required to activate the zhenqi, because the Thunderbolt Tree's energy source was the endless lightning that fell from the clouds in the sky. Cheng Fei only needed to divide a small portion of the Power of thunder and lightning zhenqi and his own Zhen Qi to control the Thunderbolt Tree's attack.
"Spatial imprisonment!"
Facing the sky full of lightning attacks, Cheng Fei was even using spatial imprisonment nonstop, causing the Tetra-winged Golden Silkworm's speed to slow even further.
The Tetra-winged Golden Silkworm had not realized that its speed had already decreased. It was still piercing through the lightning attacks and the spatial imprisonment. Whether it was the lightning attack or the spatial imprisonment, they were all activated by Cheng Fei's Fifth Stage. Although the Tetra-winged Golden Silkworm could use the peak of the Fifth Stage to penetrate the true qi, the difference between the two was not that huge.
"The Tetra-winged Golden Silkworm has descended." Cheng Fei saw that the Tetra-winged Golden Silkworm had fallen into the midst of lightning and spatial imprisonment. Although it had released its full strength, it was still limited.
"The golden silkworm's speed isn't that fast anymore." Zi Luolin also saw it. Under the lightning that filled the sky, the Tetra-winged Golden Silkworm was struck by the lightning. Although it relied on its true qi to penetrate its body and ignored the lightning attacks, its speed had indeed slowed down.
If he slowed down, Cheng Fei's goal would be achieved.
"Eye of Death!"
The Power of soul zhenqi surged, and a Eye of Death formed in the sky, becoming huge in the blink of an eye!
"Soul force!"
A stream of Cheng Fei's soul force was injected into the Eye of Death, intertwining and fusing with the Power of soul zhenqi inside the Eye of Death, forming an even more powerful Eye of Death.
"death gaze!"
The Eye of Death emitted a deep and mysterious light. When it landed on the Tetra-winged Golden Silkworm's body, it was shrouded in black light.
The reason why Cheng Fei did everything he could to lower the speed of the Tetra-winged Golden Silkworm was so that it could suppress it. After all, Cheng Fei's Power of soul zhenqi was only at the peak of the fourth stage, even if it was mixed with the soul power of the fifth stage, it was still far from being able to suppress the full speed of the Tetra-winged Golden Silkworm.
Fortunately the time was ripe, Cheng Fei unhesitatingly used his Eye of Death!
The Tetra-winged Golden Silkworm was enveloped in black light, and its body actually stopped moving for an instant.
"Now is the time!"
Cheng Fei's eyes flashed as he weaved a strange Seal in an instant, emitting a dangerous light!
"Soul Suppression!"
Boundless soul force surged out, following which the strange Seal arrived in front of the Tetra-winged Golden Silkworm in an instant.
Ying!
The Tetra-winged Golden Silkworm had just recovered from the suppression from Cheng Fei's Eye of Death, but it realised that another Seal was flying over. The Tetra-winged Golden Silkworm felt that something was wrong, but it was too late to dodge, the weird Seal had already landed on its body.
Weng...
A speechless voice sounded out in Zi Luolin's mind, and even with Zi Luolin's cultivation, she was stunned for a moment.
"It's soul force!" Zi Luolin immediately reacted, and the eyes she looked at Cheng Fei with were filled with shock, "What a thick soul force!"
Soul force was the hardest power to train because it involved a person's soul, and the soul was incomparably fragile! Therefore, among the human experts, there weren't many who could grasp spiritual qi. For someone like Cheng Fei, who had comprehended spiritual qi to an extremely profound level, it was even rarer.
The strange Seal landed on the Tetra-winged Golden Silkworm's body, and the ordinary Tetra-winged Golden Silkworm sank into a coma due to the soul force.
"If a group of Tetra-winged Golden Silkworm forms a formation, their soul force can also complement each other, making them immune to all soul attacks. It's impossible for you to suppress the Tetra-winged Golden Silkworm like this." The Hui Tian Tower said in Cheng Fei's mind, "However, this Tetra-winged Golden Silkworm is only one person, and you managed to find a loophole."
"Heh heh." Cheng Fei laughed, he knew that the Hui Tian Tower was right. In order to make it possible for Cheng Fei to subdue an ancient mutated Tetra-winged Golden Silkworm, he had to make full use of them!
That strange Seal was a "Soul Suppressing" method recorded in the "Servant Soul Method" that the Hui Tian Tower had passed down to Cheng Fei!
The Servant Soul Method came from an ancient sect called the Nefarious Almighty Sect and was the core technique of this sect. The Slave Soul Method came from an ancient sect called the Nefarious Spectral Sky Sect and was the core technique of this sect.
It could be imagined how powerful it would be. Even Cheng Xianer, who was two or three stages higher than Cheng Fei in cultivation back then, could only be willing to become Cheng Fei's servant after receiving the Slave Soul Art.
Therefore, it was not difficult to enslave the Tetra-winged Golden Silkworm with the Slave Soul Incantation.
"Slave!"
Another different Seal was finished weaving it with her soul energy. Then, he raised his palm and gently landed it on the top of the Tetra-winged Golden Silkworm's head. After that, he rushed into the depths of its brain.
The unconscious Tetra-winged Golden Silkworm felt as if there was something on its soul that was invisible and intangible, yet was real. Under the influence of that thing, it clearly wished that it could tear Cheng Fei to pieces because its subordinate had killed him. However, it was unable to avoid the emergence of another line of thought that produced an emotion of reverence for Cheng Fei.
The Tetra-winged Golden Silkworm was enslaved by Cheng Fei using the Slave Soul Incantation. Only now did Cheng Fei know why he was attacked by the Tetra-winged Golden Silkworm.
So the silkworm shaped beast that Cheng Fei and Cheng Fei met before was the subordinate of a Tetra-winged Golden Silkworm. Sensing that his subordinates had been killed, the Tetra-winged Golden Silkworm stopped devouring the ore and rushed over to avenge him.
