Lin Yu was at the bottom of the cold and dark water, and his figure kept sinking downward.

This was the second time he had entered the Cold Pool, and this time his goal was to go straight to the bottom of the pool and check the situation of the Iron Wire Gu below.

There was a trap door in the northwest corner of the Demon Sealing Net that could be opened, Tang Shouyi could use his internal strength to open that trap door, and Lin Yu had no choice but to enter the lower layer of Hantan.

Lin Yu didn't use the vajra for lighting, the iron wire Gu under the water was very sensitive to light, and he didn't want to alarm them too early.

In the darkness, Lin Yu sank to the northwest corner, and soon arrived at the sealing net in the middle, he groped for the cold sealing net with his hand, and then lightly tapped it with his hand a few times.

Buzz –

A moment later, a jolt came along the iron cable, and the sealing net below made a crackling sound, parting in the middle, revealing a narrow passage that could be used in and out.

Lin Yu's body twisted, and he passed through the sealing net along this passage, and not long after he passed through, a crackling sound sounded, and the sealing net behind him closed again, blocking the bottom of the pool again.

Below the sealing net was the world of Gu worms, Lin Yu didn't dare to be careless, he floated his entire body in the water, and then used his right hand to pull out the magic weapon peach wood sword from behind his back, and stretched it out flat.

Then he stretched out his left hand and pointed his fingertips upward, withdrew his two fingers and made three fingers towards the sky to make the Three Clear Mudras, and silently recited the mantra in his mind.

"The sun and the moon are all clear, and all the evils are turned into dust. ”

Buzz –

The peachwood sword body let out a humming sound, and then emitted a pale red light, which stood out at the bottom of the dark pool, like a lone star hanging in the sky.

This red light is different from the golden light of the vajra, and it is infused with the characteristics of peach wood, which has a certain dispelling effect on Gu insects.

With this red light body, Lin Yu began to continue to sink, and obviously felt that the water temperature was getting lower and lower, and the resistance he encountered was also increasing.

Thousands of Iron Wire Gu may lurk in the chaotic waters around them, ready to rush up at any moment and devour all the flesh and blood they can touch.

Ordinary people are in such a terrifying darkness, and they have to continue to dive down, I am afraid that their spirits have collapsed.

Lin Yu still maintained his usual calmness, silently calculating in his heart while sinking.

10 meters, 20 meters, 25 meters......

In the complete darkness, Lin Yu used the light of the peachwood sword to vaguely see a continuous gray gloom in the distance below.

As we continued to dive, the gray gradually became clear, and it was a large flat pool bottom, covered with a thick layer of black aquatic plants, swaying slightly in the water.

The red light shone on the aquatic plants below, and the chaotic darkness immediately caused a commotion, and large areas of aquatic plants squirmed and fled in all directions, and soon a bare rock pool bottom appeared.

Lin Yu's brows furrowed slightly, these black "water plants" were naturally iron wire Gu, it seemed that these iron wire Gu had grown all over the bottom of the pool, and there were thousands of them!

Lin Yu held the peachwood sword with one hand, slowly sank to the bottom of the pool, stood firm on the hard rock with both feet, and then reached out and took out a piece of array cards from his pocket.

Although Lin Yu had only made more than thirty array cards now, he must now make a space at the bottom of this pool to ensure his safety.

Lin Yu held the peach talisman with one hand, slapped it downward, and with a muffled sound, he slapped the entire array card into the rock at the bottom of the pool.

Then Lin Yu held the peachwood sword in his hand and slowly walked forward at the bottom of the pool, the red light of the peachwood sword came, and the fluttering iron wire Gu at the bottom of the pool scattered and fled.

He took a picture of a square card at a position of seven steps to the left and right, and laid out a simple five-square array.

As long as there is this formation as a backup, even if tens of thousands of Gu worms are frantically surging, Lin Yu can retreat to the formation and be invincible.

The array card was embedded in the ground, emitting the same red light as the peachwood sword, and the tens of thousands of iron wire Gu around were always squirming outside the light, and none of them dared to take a step beyond the thunder pool.

After securing this five-square array, Lin Yu held the peachwood sword in his hand and looked at the center of the dark and chaotic pool.

The bottom of this cold pool is so clean, there is not even a single animal carcass, it is really too abnormal!

An uneasiness rose from the bottom of Lin Yu's heart, the Iron Wire Gu had been at the bottom of the cold pool for a hundred years, it shouldn't just be such a quiet reproduction.

And the humanoid Gu worm that I had seen before did not appear again.

It's useless to get entangled here, only by exploring the entire bottom of the pool can we find the truth, Lin Yu raised the peachwood sword in his hand and walked towards the center of the bottom of the pool.

Stepping out of the edge of the five phalanxes, the pool on his side suddenly rippled, and Lin Yu immediately turned his head in vigilance.

I saw a black shadow rushing towards him, spreading his only remaining arm, like madness!

It was the monster that had been gathered by the Iron Wire Gu that I had seen in the water before!

It turned out that this monster had already sensed Lin Yu's existence, and the Gu worm crowd that had been lurking around before did not attack until this moment!

Lin Yu injected more spiritual power into the peachwood sword, and the red light suddenly flourished, and the monster was shrouded in red light, and suddenly let out a squeaky scream!

Lin Yu held the peachwood sword in his hand and slashed down with a sword in the face of the monster!

With a soft pop, the red-light peachwood sword easily split the humanoid monster in half from head to tail, and a continuous squeak sounded, and the large piece of iron wire Gu that was cut by the blade turned into gray-white corpses and fell to the bottom of the pool.

But the rest of the Gu insects that were not cut by the peachwood sword scattered separately and fled around, leaving only a monkey skeleton split in half in an instant, lying quietly at the bottom of the pool.

Lin Yu looked at the bones that had been cut into two pieces at his feet, his brows furrowed slightly.

The Peachwood Sword was indeed useful against the Wire Gu, but it could only be completely killed by attacking it directly.

There are more than 10 million Gu insects in this pool, if you use a sword to cut it, won't it be until the Year of the Monkey and the Horse Month, it seems that you still have to rely on the formation.

Lin Yu looked at the darkness in the center of the waterhole, calculating the time when he entered the water in his heart, he had not yet cultivated his innate body, and there was a certain limit to the use of the internal breath cycle, and the breath could only last for about an hour at most.

Now that Lin Yu has been in the water for half an hour, it is almost time to return to the water for ventilation, otherwise the breath will be insufficient, and Lin Yu's strength will be greatly reduced.

Need to hurry up, Lin Yu clenched the peachwood sword and continued to walk towards the center, the red light opened the way, and the surrounding Gu insects retreated one after another, and soon a black and heavy giant more than ten meters high appeared in front of him.

Lin Yu was slightly stunned, there is a hill in the center of the bottom of this pool?

"Roar—"

A low roar sounded in the depths of the darkness, and then a black tentacle more than ten meters long waved on the giant object, sweeping towards the place where Lin Yu was standing, stirring up a turbulent flow in the surrounding pool!

Lin Yu's face changed suddenly, this was not a small mountain, but an aggregate of countless iron wire Gus!

This is the Gu King that tens of thousands of Iron Wire Gu have multiplied at the bottom of the pond for a hundred years!
