After walking for a while, water began to drip on the rock wall, and there was a ding-dong sound.

From time to time, small pools are formed in the grooves.

Hua Qianyu's aura also faded a lot.

The two of them walked forward quickly, using their stealth skills to the fullest, and there was hardly any sound.

They follow in the footsteps of their predecessors, of course, much faster.

As he walked, Lang Xiao discovered another thing that shocked him.

The ground in front of us was not only rocky, but also dirt.

What's even more incredible is that on a rock wall three meters above the ground, there is a small tree.

The little tree was shining silvery, almost the same color as the ore dotted on the rock wall.

If you don't pay attention, you won't be able to spot it.

Because it was just in the gap between two rock walls.

"It's amazing, there's no sunlight, there's no photosynthesis, how did this little tree grow?"

Chu Xunyu was also taken aback.

"For most plants, it is true that they need photosynthesis to survive, but there are a few that do not, as long as they have energy support, they can survive." Lang Xiao looked at the surrounding environment and was a little surprised: "Could it be that these ores are providing energy for the little tree?" ”

Chu Xunyu nodded and said: "It is indeed possible, photosynthesis is the process of making organic matter, just like human eating, but if there is energy directly injected into it, it is not impossible." ”

Lang Xiao was eager to try: "The small trees that can grow here are definitely not ordinary, we will dig them out and study them." ”

Chu Xunyu nodded and said, "Okay, you wait." ”

She took a deep breath and ran and leaped to her feet, startled.

Suddenly, a cold light flashed, and the Qiushui Divine Sword stabbed out.

While!

To her surprise, her sword was aimed at the soil beneath the tree.

But she never expected that this soil was not real soil, but extremely hard rock.

But the power of this sword is that even a rock has to shatter.

In fact, nothing has changed in the rocks.

Chu Xunyu didn't believe in evil, so he leaped up again, stabbing three swords in a row.

Dangdang!

Sparks splashed, and the rocks were unscathed.

Chu Xunyu said in surprise: "How is this possible? Could it be that this tree grows in a rock? ”

Lang Xiao said: "No, I feel a strong vitality from this small tree, this small tree is strange, it must be a treasure." ”

Chu Xunyu frowned: "Even if it's a treasure, what's the use of not getting it." ”

Lang Xiao said: "Let me try." ”

Chu Xunyu handed the sword to Lang Xiao.

Lang Xiao observed it and found that this thing that looked like soil was actually harder than a rock.

He leapt up, shouted loudly, and struck his sword like the wind.

Puff puff!

Lang Xiao's arm shook, and seven or eight swords stabbed out in an instant.

He landed, took a deep breath, and leaped up again.

Snort!

This time, Lang Xiao changed his strength, and the internal force vibrate, directly connecting the holes that were originally pierced into a line.

When he jumped up for the third time, Lang Xiao had already picked this small tree at the tip of the sword.

Chu Xunyu said in surprise: "Is this still soil?" ”

Lang Xiao said: "This is not soil, but mineral essence, no wonder it is harder than rock." ”

He felt it with his hand and was amazed.

Chu Xunyu also touched it with his hand and said, "There are no wonders in the world, this is clearly an iron tree!" ”

This is not the kind of iron tree that people talk about, but a tree as hard as iron.

The tree is no more than a foot tall, and its branches and leaves are lifelike.

But even a leaf is harder than iron.

When he struck it with a sword, he made a dangling sound.

But Lang Xiao knew that this was definitely not an iron tree, but a real tree.

The vitality contained in it was much more than all the mist essence that Lang Xiao had absorbed combined.

Lang Xiao was puzzled.

Could it be that the fog is emitted by this small tree?

"Lang Xiao, look at the cave wall, those ores have dimmed."

Chu Xunyu suddenly exclaimed.

Lang Xiao looked up and was also surprised.

I saw that the ore that was originally like a pearl began to dim.

It's like a light bulb that has lost power and is gradually going out.

He looked at the little tree in surprise and said in shock: "Could it be that the reason why these ores shine is actually that it is providing energy?" ”

Chu Xunyu felt ridiculous: "This is impossible, although this little tree is magical, it is not so powerful." ”

Lang Xiao returned the sword to Chu Xunyu, took the small tree and said with a smile: "I'll know when I go out for a detailed inspection, let's go, it's important to get down to business." ”

He grabbed the tree and was startled.

The roots of this little tree were as hard as steel.

Now that he was held in his hand by Lang Xiao, the whisker turned soft, and he grasped his palm tightly like a tentacle.

Lang Xiao was in a cold sweat on her back, and she subconsciously wanted to throw the little tree out, but found that this whisker was like being stuck in the flesh, and she couldn't throw it away.

His face turned pale, and he took a deep breath, his internal force surging wildly, trying to shake it away.

Who knew that the internal force exploded, but it was like a mud cow entering the sea.

The little tree is like a greedy glutton, directly swallowing Langxiao's internal force without causing the slightest wave.

Lang Xiao was terrified in her heart, and the Five Elements Mental Law worked, evolving into a fiery body.

The scorching internal force rushed out, and the palm of his hand was suddenly red, as if it was about to burn.

The terrible temperature made Chu Xunyu startled, and hurriedly moved out of the way.

"Lang Xiao, what are you doing?"

She also noticed that something was wrong with Lang Xiao, and couldn't help but get nervous.

Lang Xiao's palms became more and more red, and in the end, a flame rose from the sneer.

Chu Xunyu couldn't help covering his mouth, so surprised that he couldn't speak.

Although the flame was not big, Chu Xunyu, who was a zhang away, also felt the power of this flame.

Everything, it seems, can be melted.

What's even more surprising is that under the scorching heat, the little tree actually changed and became fiery red.

It's like Lang Xiao holding a burning tree in her hands.

Lang Xiao's expression was serious, and the Holy Fire Heart Method was working, wanting to burn the small tree.

But he found that although his flame was stronger, it was still useless.

Not only did it not cause damage to the Iron Tree, but the Iron Tree was absorbing the power of fire.

Lang Xiao gritted his teeth, and the internal force changed again.

This time, the power of ice came directly.

The extreme heat was followed by an extreme cold, and the expansion and contraction of the heat would cause great damage, and he did not believe that the little tree could withstand it.

But to his great surprise, this little tree is like a bottomless pit, and no one refuses.

The power of ice was also absorbed by the roots, without causing any damage.

Lang Xiao's head was full of black lines, and he gritted his teeth and was ruthless.

He didn't believe that this thing could withstand the power of the five elements.

As a result, the Five Elements Mental Method continued to change, and the internal forces of the five attributes continued to enter Xiao Shu's body one after another.

Lang Xiao was completely dumbfounded.

Five kinds of internal forces are fed into the small tree, and it turns out to be the same result.

The only difference is that the color of the tree has finally changed.

The five colors are staggered, and the lights are brilliant, just like a colorful landscape tree.

Chu Xunyu was also full of strangeness and couldn't speak.

The small tree is still changing, the branches and leaves are constantly twisting, and the trunk is rapidly elongating.

For a moment, Lang Xiao even had the illusion that this thing had actually turned into the shape of a sword.

He rubbed his eyes and looked again, but the tree was back to its original state.
