Relying on the air light film to corrode the ground, Su Zhong went all the way down.

At first, it was smooth, the light film released a searing erosion energy, and the hard rock was like dead wood, turning into powder at the touch of it. Under the powerful force of the spirit, it was directly pressed into the surrounding rock wall.

But as it went deeper, the pressure made the rock harder and harder. The erosion rate of the aura light film was slowing down, although there was only a trace of it, but Su Zhong clearly felt that the speed was slowing down.

Su Zhong ignored it and continued to move down. But the speed is getting slower and slower. In the beginning, he could descend thousands of meters in an hour. But now, he can only move less than a hundred meters forward in an hour!

The release of mechanical air erodes the rocks and widens the passages. It was dark underground, and Su Zhong couldn't feel the passage of time at all.

Since the siphon of life, eating is no longer necessary. Without the reminder of three meals, Su Chong's sense of time became more and more blurred. I don't know how long it was, but he suddenly stopped.

Snort!

A burst of white smoke rose up, and Su Chong raised his eyebrows. The erosion of the air light film has actually encountered obstacles?

"The previous rocks were hard, but they couldn't stop the erosion. Even if you can resist, you can't stop it at all. Now this stone can actually block the spirit? Su Chong's eyes narrowed, and he reached out to touch the pitch-black rock.

Laugh at!

Su Chong raised his eyebrows, the temperature is so high! Withdrawing his hand, on the palm of his hand, black and red lines are pervasive. Inspired body protection?

Airplanes!

The aura spread suddenly, and everywhere it passed, all the rocks turned into black ash, and quickly squeezed into the surrounding rock formations.

The space around him expanded rapidly, and a black wall with a slight arc appeared in front of him.

Not far away, the roots of the huge World Tree pierced into the rock wall. The two are tightly fitted together, without a single gap, as if they have grown together.

Looking around, the entire black wall went deep into the surrounding rock wall, and I didn't know where it extended: "It's such a big wall, it's impossible to go around." ”

"Lava must be right behind here!"

Walking to the roots of the World Tree, Su Zhong stretched out his hand and pressed it on the rough roots.

Siphon of life!

Airplanes!

A stud of green energy was suddenly dragged out. The huge amount of life energy quickly integrated into Su Chong's body. Letting go of his hand, Su Zhong stopped continuing to absorb the life energy of the World Tree.

He could feel the entire World Tree, the majestic vitality of the earth, as if it were bursting into the sea. Before he activated the life siphon, no matter how old the ancient tree was, a few breaths could be devoured by him to clean up the energy.

"The enhanced version of the siphon of life can only shake one tendril?" Su Zhong could even feel that there was a vague instinct in the world, an instinct that bound and absorbed the energy around him!

"No wonder it can absorb magma, the life field is so powerful. The powerful life force field restricts its own vitality and devours all the energy around it at the same time! Su Chong felt that he was very similar to the World Tree.

He has a Dao seed to control his own life force, and the World Tree also has its own life field. He has a life siphon to absorb energy, and the World Tree also has powerful roots and branches to absorb energy.

Or rather, it's a commonality of powerful individual creatures! All have a kind of instinct to constantly condense inward and make their heritage stronger! ”

It's simply impossible to absorb the World Tree like any other tree!

"Only by breaking through the other party's life field can you completely absorb the World Tree. This is too inefficient compared to the lava that is readily available. ”

Su shook his head and gave up the idea of devouring the World Tree.

"Although it can't be completely swallowed, it can still erode a section of roots." Reach out and pat the rough roots. The tremor erupted.

Bang!

The roots in front of me instantly turned to powder. Unfortunately, the powdering only spread for more than ten meters before stopping, revealing the grayish-white wooden part.

"I can only destroy this small section in front of me." Su Zhong sighed at the strength of the World Tree Life Field. Without deliberately exploding, the siphon of life can only devour a small part of the roots.

Call!

A hot wind blew suddenly, and Su Chong's clothes were blown with a grin.

In the near-enclosed underground, a scorching wind was blowing. Turning his head, he saw that the roots that were still embedded in the black rock wall just now, and the tightly closed roots revealed a gap.

A faint red glow came out of the cracks, and it was from where the hot wind blew.

No longer hesitating, Su strode into the gap. Turning around, the eyes suddenly lit up.

A huge magma lake appeared at Su Chong's feet. At first glance, you can't see the border!

It's an egg-like underground space full of bubbling magma underneath. The surrounding rock walls are pitch black, and all of them are hard rock that has been solidified by the melting of magma. Its construction is so complex that even the cutting-edge equipment of a top-tier laboratory cannot replicate it.

At the top of the semi-arc, countless black stone pillars hung down, plunging into the magma lake below. His heart moved, and Su Zhong looked carefully. Immediately found out that where there was a stone pillar, it was simply the roots of the World Tree! There is one next to me, and it goes straight into the magma under my feet!

"No wonder the roots of the World Tree are so difficult to swallow, even the heat of magma can withstand it, it can be seen that the hardness of the wood, how can it be so good to destroy?"

"This is really a holy place for cultivation!" Such a large magma lake is much larger than the volcanic lava of the Dry Killing Mountain!

Su Chong's eyes lit up, and he jumped down directly, and actually jumped directly into the magma lake.

Snort!

Almost as soon as he entered the magma lake, all the clothes and hair on his body were burned clean. Almost instinctively, the aura light film suddenly erupted, completely enveloping Su Chong. On the skin, black-red scales and nails emerge, covering the whole body. The flame mark at the center of the eyebrows is becoming more and more distinct, constantly swaying.

Hiss!

Su Zhong gasped for a breath of hot air, despite the aura protection. But the erosion of the scorching heat is too painful!

In just a moment, the skin was already burned by the high temperature, and Su Zhong even smelled the smell of burnt meat!

Dao Seed trembled suddenly, and a cool air flow rose from his body. The burned skin muscles are quickly restored.

The black scorch cracks and peels off, revealing white and tender skin. But the next moment, the newly recovered skin was immediately burned by the high temperature.

"Suck me!"

The Dao Seed trembled violently, and a huge devouring power suddenly appeared. The bright red magma around him suddenly dimmed. Immediately after that, it was scorched red by the surrounding magma heat****** and the seventh stage of the dragon suddenly activated, and the energy swallowed into the body was quickly sent to all parts of the body, constantly transforming the body.

Su Yan clenched his teeth, and the muscles of his whole body continued to tremble. There seemed to be a small mouse crawling under the skin, bulging up sarcomas and constantly scurrying in the body.

This is no longer an enhancement, but a complete transformation! Su Zhong could even hear the faint sound of bones shattering! That's the sound of bones shattering and reshaping!

The black-red lines on the surface of the body suddenly brightened, the black became deeper, and the red became more and more vivid. From a distance, it looks like a lava lake underground, mottled.

Ding Ding Ding!

In my mind, the data in the skill panel changes dramatically.

The experience value data behind the seventh stage of the Demon Dragon continued to climb at a speed that was almost visible to the naked eye.

In a quarter of an hour, it has already soared by more than a hundred points!
