The largest part of the octopus's head was about three to four meters wide.
Each of its eight tentacles was dozens of meters long, floating on the surface of the sea, looking extraordinarily terrifying.
As the giant octopus emerged, the other marine creatures surrounding the sea surface fell into a brief silence.
Moreover, the main reason was not just the enormous size of the giant octopus.
It was the wild and powerful aura radiating from it.
Even from the top of the volcano, Fang Yun could feel this aura.
Although he had never seen what a demon beast looked like, he instinctively knew that this aura belonged to the demonic energy unique to demon beasts.
Upon seeing the giant octopus, Fang Yun's expression changed dramatically.
Indeed, the worst had happened.
The fruit of the metallic plant had ultimately attracted the appearance of the demon beast.
Faced with this situation, Fang Yun could only continue infusing vital energy while commanding the vines to climb down the mountain.
Unfortunately, the metallic plant's absorption rate of vital energy was limited.
Even if he infused it desperately, he could not make the fruit mature instantly.
So in this situation, Fang Yun could only try to delay the approach of the giant octopus as much as possible.
After the giant octopus emerged on the surface, its eight tentacles began to thrash violently.
Soon, they reached the beach and quickly moved toward the volcano.
Fortunately, at this moment, the vines controlled by Fang Yun also swiftly made their way down the mountain and raced toward the giant octopus.
Compared to the giant octopus's massive size, the vines appeared significantly smaller.
Moreover, due to the distance, Fang Yun couldn't command the vines as flexibly as he had done on Turtle Ridge Island.
As a result, when the vines rushed forward, they attempted to entangle the giant octopus but were quickly thwarted.
With its eight tentacles, each several dozen meters long, the giant octopus would not give the vines any chance.
One of its tentacles swung violently toward the head of the vines, directly sending them flying.
It then quickly approached, with its eight tentacles striking the vines in succession, continuously forcing them into the ground.
Fang Yun, far atop the volcano, furrowed his brows deeply at this scene.
If he had been directing them in person, the vines would have performed better.
But now, being too far away, it was unrealistic to rely solely on the vines to stop the approach of the giant octopus.
Thus, Fang Yun shifted his focus to the spirit insect that was continuously circling above the metallic plant.
The reason he hadn't sent the spirit insect out earlier was because of the attraction of the metallic plant's fruit.
Fang Yun worried that the command he issued might not be followed by the spirit insect.
But at this point, there was no other option.
If the giant octopus reached the top of the volcano, it would be a huge problem for him.
As Fang Yun gave the command, the spirit insect's body noticeably paused for a moment.
Then, it spiraled anxiously above the metallic plant.
Seeing this, Fang Yun did not blame the spirit insect, as he knew it was a conflict between his command and the insect's instincts.
It was not the insect's intention!
Moreover, the spirit insect itself had limited intelligence at that moment.
It couldn't easily resist its instinctual drives.
However, under Fang Yun's repeated commands and the continuous promise that the fruit would belong to it, the spirit insect seemed to understand.
After circling above the metallic plant a few more times, it transformed into a blue-gold light and shot toward the giant octopus.
This terrifying speed instantly invigorated Fang Yun from afar.
Unfortunately, perhaps due to its instinctual caution, the giant octopus suddenly emitted a blue light from its head at the last moment.
Although this blue light could not block the blue-gold light transformed from the spirit insect, it did manage to momentarily obstruct it, allowing the giant octopus's head to tilt to the side.
Consequently, the blue-gold light transformed from the spirit insect penetrated the edge of the octopus's head.
Though this strike did not hit the giant octopus's most vital spot, it still caused considerable damage.
Blue blood gushed from the wound, causing the giant octopus to thrash its tentacles wildly in place.
Seizing this opportunity, the previously driven-down vines, which had lost many of their spikes, managed to break free from the ground.
They then wrapped around several of the giant octopus's tentacles with their bodies.
The sharp spikes plunged directly into the tentacles of the giant octopus, releasing a large amount of blue blood.
This provoked the giant octopus to keep flailing its tentacles, but it couldn't shake off the vines' grip.
Meanwhile, the spirit insects in the sky, transformed into blue-gold light, continued to circle around.
This made the giant octopus hesitant to focus all its attention on the vines.
After all, the threat posed by the spirit insects was far greater than that of the vines.
Seeing this scene from the mountaintop, Fang Yun nodded in satisfaction.
It seemed that his two combatants, even without his direct command, still demonstrated a fair amount of teamwork.
This reassured him significantly.
He continued to infuse vital energy into the metallic plant.
Before long, the metallic plant began to convey feelings of satisfaction.
Simultaneously, the fruit stopped emitting the strange wave.
Seeing this, Fang Yun finally breathed a sigh of relief.
He had endured this dangerous moment once again.
It seemed that next time he needed to hasten the maturity of the metallic plant, he must take precautions.
This time had truly been perilous!
Without bothering to gather the metallic plant's fruit, Fang Yun directly flew down the mountain.
The priority now was to deal with the giant octopus.
Only by taking care of the giant octopus could Fang Yun return with peace of mind to observe the ripening metallic plant.
Not long after, Fang Yun arrived near the giant octopus.
In this short span of time, the spirit insect had again pierced a wound at the root of one of the giant octopus's tentacles.
Blue blood had already soaked the nearby ground.
However, compared to the agility of the spirit insect, the vines, without Fang Yun's guidance, appeared somewhat rigid.
They struggled to keep entangled around several of the giant octopus's tentacles.
Even though many of their spikes had been smashed by the giant octopus, and their bodies were even torn into pieces, they still firmly held onto the giant octopus's tentacles out of instinct.
Seeing this, Fang Yun shook his head in a mix of sorrow and helplessness.
