The underground wind cave in the Yin of Cangmang Mountain is the time for the wind to vent at this time, so from a distance, the whole area is like the Yin Wind Demon Domain.

But it is precisely because of this that it is the best time for Zhang Tong and Shang Zhu to go in!

Although the catharsis of the wind makes the entire Cangmang Mountain Yinyin look like hell, the more this is the case, the more the wind will be calmer in the hole of this underground wind cave.

If you wait until the wind returns, then the two compartments will be sandwiched outside, one inside and the other......

At that time, I am afraid that the power of this gang wind will be doubled!

In such a situation, even if Zhang Tong has a talisman treasure and a master of immortals like Shang Zhu, I am afraid it will be difficult to protect it!

After getting ready, Zhang Tong directly merged his human sword, turned into a long red sword light, forcibly tore a pillar of wind, and then flew down towards the cliff cave.

At this time, his whole body was wrapped in the sharp sword aura of Xi He Sword, and coupled with the huge power of Xi He contained in Xi He Sword itself, these wind pillars could not stop him for the time being!

But just when he had fallen less than a hundred feet, in the gap in the mountain wall, a gust of yin wind suddenly swirled and sprayed out towards him.

This wind is different from the Gang wind outside, and in this wind, there are also streams of black gas.

At this time, the mountain wall is like boiling water in a pot, spurting out suddenly, completely blocking the road ahead.

Vaguely, Zhang Tong even saw that there were countless black crystals the size of fingernails hidden in the wind, and the color was transparent, like crystal petals......

The moment he landed at the entrance of the cave, Zhang Tong felt that the temperature around him had suddenly dropped a lot.

In an instant, Zhang Tong also understood.

The pitch-black crystal petals he saw just now were the black frost qi of the Xuan Ice that had accumulated for thousands of years in this wind tunnel.

Although it seems that the momentum of these winds around them is not as strong as the wind pillars that lead to the sky outside......

But anyone with a discerning eye can see that the power of these yin winds they have to face now is far greater than those mighty wind pillars.

Even if it is some ordinary magic weapon, if it is blown by the black wind in front of me, I am afraid that it will be blown into powder directly...... right.

Just when Zhang Tong observed the dangerous environment around him.

Shang Zhu, who had been following him, also came to his side at this time.

Zhang Tong turned his head and saw that Shang Zhu's whole body was wrapped in a layer of colorful brilliance at this time, and those ice flowers condensed by the Gangfeng and even the Xuanbing Black Frost Qi would be directly dissolved after touching this brilliance.

"The Great Five Elements Extinction Divine Light ......"

Zhang Tong is naturally very familiar with this method, because now he can use it himself.

However, with his current mana alone, the power of the Great Five Elements Extinction Divine Light that he can use is probably slightly inferior to Shang Zhu's.

This is a gap in hard power, and it has nothing to do with skill proficiency, so Zhang Tong has nothing to do for the time being.

"This wind tunnel will be even more dangerous in the future, fellow Daoists should be careful. ”

Zhang Tong said solemnly.

Now the two of them have just arrived at the entrance of the cave, and they don't know how deep it is!

And this wind tunnel is the home of the ice silkworm, so it can come and go here as it pleases.

This is also an important factor that is very unfavorable to Zhang Tong and the two.

Shang Zhu nodded.

An old guy like him, who has been cultivating for hundreds of years, can be said to be well-informed.

No matter what kind of place it is, as long as there is danger, they will cheer up their spirits......

Because those careless guys have long been dead for an unknown number of years......

Maybe you can't even see the grave grass anymore!

All the way down......

At the beginning, Zhang Tong and the two were still very fast.

However, after hundreds of feet, the two had to take the initiative to slow down.

On the one hand, at this time, there were more and more black frost qi in this underground wind cave, and it had almost reached the point of filling the entire cave.

And because at this time, in the depths of the cave below, there was a suction force that was constantly sucking them downward, as if to pull them directly into this bottomless abyss.

"Fortunately, I didn't let Baoqing, the little fox, come in here before, otherwise I'm afraid something would have happened at this time!"

Feeling that the mana in his body was surging out like a tide, supporting his Xi and sword light, Zhang Tong couldn't help but secretly rejoice in his heart.

"Although this Xi and sword light have a restraining effect on the Xuanbing Black Frost Qi in this cave, it is not a treasure to protect oneself after all, it seems that the Dragon King Mirror is still going to be used to protect oneself!"

Originally, I was thinking that my Dragon King Mirror would not be able to appear in the world, but now it seems that it is not necessary!

As soon as his heart moved, a simple bronze mirror appeared above Zhang Tong's head, and then a layer of blue light sprinkled down from the mirror, wrapping Zhang Tong's entire body in it.

Looking at Shang Zhu again, at this time, he could no longer rely on his Great Five Elements Extinction Divine Light alone to protect himself, and above his head, a small five-colored divine mountain actually appeared.

Zhang Tong was slightly surprised in his heart, although he didn't know what kind of treasure this was in the other party's hand, but judging from its power, it was definitely a rare Five Elements Supreme Treasure!

Zhang Tong's guess was good.

The name of this magic weapon is called the Five-Colored Divine Mountain, which is made by Shang Zhu who collected a large amount of the essence of the five elements, supplemented by the polar yuan magnetic essence qi, and refined it.

This treasure is not only offensive and defensible, but also because of the unique ability of this Yuan Magnetic Essence, it can be said that it is definitely a rare treasure to collect other people's flying swords!

Since the two of them have the ability to support themselves at the same time, it is natural that they need to continue to go deeper.

After going deep into the underground wind cave for about a thousand feet, Zhang Tong and the others finally saw the ice silkworm.

The ice silkworm was only about the size of a foot, and its body was blooming with a misty white light, and it was drilling back and forth in the countless holes in the four walls, as if it was a naughty child, playing a little happily.

Now that they have met the main master, Zhang Tong and the others will naturally not be polite!

Without waiting for Zhang Tong to make a move, Shang Zhu first destroyed the five-colored divine mountain above his head, and sent out a five-color rainbow like a practice, sweeping out.

The ice silkworm is a spiritual creature of heaven and earth, and thousands of years of cultivation are also not easy.

At that time, as soon as he opened his mouth, a miserable white phosgene erupted, resisting the five-colored light rainbow. Then, a crystal clear silk thread was shot out, winding towards Zhang Tong and them.

The silk threads crossed the air, and everywhere they passed, countless white frost gases emerged and condensed together, and there was actually an extra frost bridge with a width of a few feet out of thin air.

Zhang Tong saw it clearly, it was the silk of the ice silkworm!

Seeing this, Zhang Tong did not slack off, and directly urged the power of Xihe with all his strength, instantly emptying the surrounding cold air, and the ice silk also slowly melted under the power of Xihe that completely exploded......

However, Zhang Tong didn't dare to directly use such a powerful power of Xihe to attack the ice silkworm, this time he came to subdue the ice silkworm, not to kill the ice silkworm, so he could only collect it.

Shang Zhu instantly understood Zhang Tong's intentions, and when the ice silkworm was forced by the power of Xihe, he took the opportunity to directly use the power of his five-colored divine mountain to suppress the ice silkworm.

"Zhang Daoyou, hurry up and take the opportunity to subdue this thing, my magic weapon can't hold it for too long!"

After the first blow, Shang Zhu immediately reminded him.

Seeing this, Zhang Tong naturally did not hesitate, and directly dodged to the side of the ice silkworm, and then in Shang Zhu's stunned eyes, he stretched out his right index finger and pointed it on the head of the ice silkworm ......!
