It was pitch black in the deep cave, and the faint light of the leaves could only illuminate the things in front of him, and no matter how far away, it would not work, invisibly giving people heavy pressure.

Even though he knew that there was an aura shield supported by Su Buyi in front of him, Su Buyi still held his breath nervously.

Unconsciously, fine sweat appeared in Su Buyi's palms, wetting the hands of the two of them.

"Don't panic, I'm here." Su Buyi clenched Su Buyi's hand and calmly accelerated the speed downstream.

Su Buyi nodded and was silent.

Slowly, the speed of the brother and sister slowed downstream, as if something unseen was blocking them from moving forward.

Su Buyi gently tugged at Su Buyi's hand, didn't speak, just looked at Su Buyi with inquiring eyes, as if wondering why it suddenly slowed down.

"It's not that I'm slowing down, it's supposed that we're in the place." Su Bu squinted his eyes, and the corner of his eye kept looking, as if he could see the situation inside through the darkness.

When Su Buyi heard this, his heart couldn't help but chuckle, "To... Arrived? ”

Su Bu nodded in surprise, and just as he wanted to speak, he was attracted by a shadow in front of him, and immediately threw the dead leaves he was holding in his hand.

"Big brother, look there!"

Su Buyi didn't think about it, and looked in the direction that Su Bujing said.

The dim light falls right there, illuminating little by little what is hidden in the darkness.

Whew... Whew... Ugh.

It was the sound of leaves rubbing against something, because the light was too dim, Su Buyi could only deduce by his sensitive ears and guesses.

Only Su Bujing can not be affected by the environment.

She saw that the part illuminated by the faint light was a dead white thing, although it was large, it was a little familiar, and she couldn't remember it when she thought about it, and it seemed to be a little reflective...

"What's that, it's big... It's so familiar. Su Bu muttered softly.

"What is it? We've seen it before? Su Buyi asked.

Under water, even if Su Buyi is no longer affected, he is an ordinary person after all, although his eyesight is excellent, he still can't break through the limits of mortals, and naturally he is not as capable as Su Buyi.

Su Buxi didn't answer immediately, she frowned in confusion at first, and thought blankly for a moment.

It wasn't until the leaves slowly fell, slowly illuminating the scene below, that she suddenly slapped her head and said:

"I see, that's the Silver Tree! That big guy is the silver tree we've seen on the shore! ”

No wonder she said that it was so familiar, it turned out to be a silver tree that can be seen everywhere on the snowy mountains!

It's just that the underwater one, which is much larger than the silver tree on the ground, is simply the product of year-on-year enlargement.

"Silvertree? Can trees still live underwater? Still grows in water holes? Su Buyi was a little unexpected.

He had thought that there might be a large swarm of snakes in the underwater cavern, that there might be huge monsters, or that it might be empty.

But no matter how much he thought about it, he never thought that it would be a silver tree that abounded on the snow.

It can be said that the Silver Tree is of no use to them except for emitting white light to illuminate the way.

You know, they were afraid that burning the Silver Tree would cause the illusionary danger they had encountered in the dead forest before, and they even used the trees in Su Bujing's Immortal Mansion to burn the fire.

Su Buyi's right index finger covered Su Buyi's eyelids, and he touched it gently, "It's Yinshu, that's right, I don't believe that the eldest brother will come and see it himself." ”

Su Buyi first felt that his eyes were cold, and then some hot heating overflowed from his eyes, and when he opened his eyes again, he could see things in the dark freely.

"It's really a silver tree, this leaf is so big, it's a lot bigger than the two of us combined!" Su Buyi was shocked by the giant tree in front of him, he seemed to have forgotten his previous nervousness, stepped forward in disbelief, and stroked a wide leaf.

At this moment, he was as small as a bug on a tree, and because of this, he felt inexplicably uncomfortable.

Not because of the darkness, nor because of the fear that the leaves are dangerous, but simply because of the discomfort of its size.

It's just that a leaf is so big, so how terrifying the body of this silver tree must be!

"It stands to reason that such a big silver tree should be glowing, why is it so black, has it passed the time to shine?" Su Bu rubbed the leaf surface and guessed.

If the silver tree in the deep cave had been lit before, they would definitely have seen things under the water from a long distance, and they would not have mistaken the water cave for a beast's eye and made a fuss.

"Maybe, it's already dark outside anyway, so why don't we swim down again." This time it was Su Buyi who proposed it.

"Big brother is not afraid?" Su Bu raised his eyebrows and asked.

"Hehe, it was a little uncomfortable at first, but now... It's just a tree, and no matter how much it does, it can't go to the sky. We've all swam here, and we can't just leave. ”

Su Bu grabbed the leaves and said, "Okay, it's decided, before we go ashore later, we will bring some underwater silver branches by the way." ”

"A silver tree of this size, even if it's just a small branch, must be very bright when it comes to light, uh... I just don't know if the branches can still shine when they are separated from the body. ”

Su Buyi patted the thick branch in front of him and said with relief: "Don't get in the way, the worst situation is nothing more than going ashore and waiting, as long as your aura is enough to consume." ”

"Don't worry, big brother, I have a sense of proportion, and we can definitely go back unscathed." Su Bu puffed out his chest and promised.

Su Buyi nodded.

My sister is not an unreliable second brother, she said she could do it, and he believed it.

Because he was afraid that the road would be scattered after that, Su Bujing took a thick and sturdy rope from the immortal mansion and tied it around the waists of the two of them.

Then, the brother and sister clung to the silver tree, groped for the branches, and walked straight downstream.

"It's bad to get lost underwater, so we must not let go of the silver tree to make sure we don't deviate from our direction." Su Buyi explained, and the corner of his eye kept paying attention to Su Buyi.

Xu is the place where the brother and sister are standing just now is at the top of the silver tree, so the branches and leaves are not luxuriant.

But as they gradually descended, they encountered more branches, and the wide leaves were stacked on top of each other, blocking the path of the brother and sister.

If it weren't for the fact that Su Bujing and Su Buyi had a layer of aura shield in front of them, which somewhat alleviated some obstacles, plus the eyesight of the two of them was not affected, and they could move freely in the water, I am afraid that it would have been delayed for a lot of time.

During the swimming, the thick rope around the siblings' waists was straightened for a while, and then floated loosely in the water, adding a bit of agility to the lonely bottom of the water.

The further down he went, the true face of the silver tree was gradually revealed in front of the two of them.

The lower part of the silver tree is larger than the top of the tree, and the branches and leaves are intertwined, and some of them are so far away that you don't even know how wide and thick the silver tree is at a glance.

Su Bujing and Su Buyi, who were wandering around, were lined like two ants born on a tree, and a single leaf could bury them.

From a distance, it looks like a miracle that it took countless manpower and material resources to build a tower, but finally sank to the bottom of the water.
