This is a huge stalactite cave, with all kinds of strangely shaped stalactites dazzling, erected, hanging upside down, crooked, and all exudes a faint colorful light.

The light in the entire underground space is not very dim. Looking at it, it is full of shadows everywhere, but the faint light is like daylight to Chen Yu.

There was a ticking sound of water everywhere, and the air was very humid.

"Is that monster powerful?"

Leading that Tong Yan to the entrance of the cave, Chen Yu asked with a smile.

Judging from Tong Yan's relaxed look, he concluded that the monster she was talking about should not be very powerful.

Tong Yan clasped Chen Yu's arm tightly and said with a smile: "We are weaker than those we have encountered, and they are monsters like big mushrooms and magic snake vines."

"It's a piranha-like thing again, haven't we got out of Uedong Mountain yet?"

Chen Yu muttered to himself in disbelief and exaggerated crying.

The map of Fengyun Continent provided by the crystal coffin contains too much information. In the past two days, Chen Yu has clearly understood that the mountainous area where he encountered Jinzhi cinnamon and the magic snake is called Zhidong Mountain.

As shown on the map, the area of ​​Mount Zhidong is not that big, just over 1,000 square kilometers.

Calculated vertically and horizontally, the length and width are at most tens of kilometers.

The two of them have walked in this mountainous area for more than ten days, and at their speed, not to mention traveling a hundred and eighty kilometers a day, no matter how bad they are, there will always be more than ten kilometers a day.

Ten days is more than a hundred kilometers, so it is far away from Zhidongshan area.

"Yan'er doesn't know what Zhidongshan is, only that the monster in the cave is similar to the big mushroom."

Feeling that Chen Yu didn't believe her words, Tong Yan curled her lips slightly unhappy.

Chen Yu didn't answer any more, frowning deeply in thought.

Could it be that there are magical formations in Uedoyama, we have been walking in circles without knowing it.

With extreme thoughts, Chen Yu also nodded to himself, feeling that his guess was very reliable.

"Although the monster is not powerful, we have to be careful. There may be a fierce big guy guarding it. Don't forget the two black-crowned cranes."

Chen Yu reminded Tong Yan.

"understood!"

Tong Yan still looked a little angry.

When they got into the cave, they held hands and stepped deep, Chen Yu urged the crystal sword in his hand to brighten and illuminate, and there was not weak light around it, just for the convenience of children.

"Look, that's the thing!"

After walking about a thousand meters in the damp and dripping tunnel, Tong Yan suddenly pointed forward.

Chen Yu looked intently and saw a large area of ​​green moss in front of him.

It was fluffy, a big green area, and the cave walls were full.

"Green channel!"

Chen Yu said jokingly, feeling that those "mosses" had no offensive power or threat.

Immediately, he felt that what was in front of him was familiar, as if he had seen it somewhere, but he couldn't remember it for a while.

Holding the Tong Yan who wanted to move forward, Chen Yu hesitated, stopped and waited, "This thing is a little weird, be careful."

Before he finished his words, the "moss" suddenly stood up without wind, and they were growing rapidly, each of which was as long as hair.

"Could it be those things?"

Now Chen Yu finally remembered seeing these "mosses" there.

He and Zier saw something similar in the underground river when he and Zi'er went to hunt Thunder Beasts, but they were not sure whether the "moss" they had seen before and now were the same thing, but they looked very similar.

The green hair on the cave wall grew longer and longer, and quickly entangled and connected to it, blocking the tunnel in front of it tightly.

Chen Yu stretched out his hand to protect Tong Yan and backed away, "They don't seem to want us to pass."

Tong Yan flipped his hand to take out the double blade of the dragon and the phoenix, and gave the dragon blade to Chen Yu, "Brother Yu, let's kill it."

"Okay!" Chen Yu took the Dragon Blade, "You go back first, brother first go try the water."

To escape to the ground, they must find an exit through the hole of the eye.

Chen Yu just took two steps forward, and a green ball as big as a fist suddenly ejected from the green hairs.

Huh!

Chen Yu's eyes are quick and his hands are quick, and he will cut it out with a single knife.

The green ball was split from it and fell in two.

After landing, he grew wild in an instant, and in the blink of an eye, Chen Yu's eyes were green.

The tunnel in front of him was blocked.

"Damn, it's changed too much!" Chen Yu exclaimed and backed away.

Tong Yan strode to Chen Yu's side and stood side by side with him, staring scorchingly at the green stuff blocking the tunnel in front of him.

Looking at it up close, you can see it more clearly. Not only are the roots of the green moss hair thin, but also very crystal clear, just like green silk just spit out.

Chen Yu handed the dragon blade back to Tong Yan, "This thing is weird and ruthless, and it is so small that the dragon and phoenix double blades can't be restrained anymore. Back up and watch brother."

I thought that the dragon and phoenix double-blade could restrain the monsters in the mountain, but the facts proved that it was not the case.

"Well, brother Yu, come on, Yan'er is optimistic about you."

As Chen Yu stepped back, Tong Yan said with a smile.

Chen Yu can always think of surprising ways to win. Tong Yan is very confident in him, almost reaching the point of blind worship.

After more than ten steps withdrawing, Chen Yu stopped, flipped his hand to take out the crystal sword, urged the sword to light up, and swiped out several swords.

"Surveillance swordsmanship, power grid!"

Chen Yu's move is a big killer, the power grid!

The purple grid appeared out of thin air, like a moving spider web, covering the front of the green moss to block the tunnel.

With a squeak, the purple power grid instantly turned the green moss into ashes.

A large amount of hairy black charcoal appeared on the cave wall.

The purple grid also dissipated, and a large amount of electrical energy was absorbed by the wet cave wall.

The power grid received a miraculous effect, and Chen Yu smiled triumphantly and turned around to raise his face, "Brother is great."

"Well, great, great."

With an excited smile on her face, Tong Yan clapped her hands and praised without hesitation: "Brother Yu is the most handsome and powerful man in the world, hehe."

"It must be!"

Chen Yu smiled more proudly, strode forward with a crystal sword in his hand, and sang loudly, "I smile proudly, smile proudly...hahaha!"

A large amount of green moss a little further away danced and swayed as he sang loudly, like water plants dancing with the waves, swaying green waves.

Without waiting for Chen Yu to approach, the green hair moss suddenly became green, and the whole cave was radiant green.

"Huh? It will shine!"

Chen Yu stopped in shock, and stretched his arms to stop Tong Yan who was following her closely, "You are waiting here, brother will kill them first."

As he said, he swung his swords again and again, and another purple grid appeared out of thin air, and the cover pressed against the green moss in front.

Puff puff……

At the moment when the purple power grid appeared, the green hair moss surged with green waves, spraying out a large number of fist-sized green light balls like a machine gun, lasing here.
