"Walk!"

Su Yi led everyone into the ninth formation.

"roar!"

Suddenly, the ancient dragon from the center of the earth roared and rushed towards them at a rapid speed.

Su Yi has fought against the ancient dragon of the earth's core more than once, so he has extremely rich experience.

The ancient dragon from the center of the earth has thick skin and strong strength.

It would be difficult to break his defense using spiritual energy or physical objects.

The simplest way to deal with it is to fight violence with violence.

Su Yi immediately used [Seven Changes of Jingzhe], transformed into a giant ape, leaped onto the body of the ancient dragon at the center of the earth, and then punched the ancient dragon's head one by one.

Bang Bang.....

For a moment, the entire formation was filled with violent collision sounds.

At first, the ancient dragon in the earth's core was still very unconvinced and kept swinging its tail to attack Su Yi.

But without exception, Su Yi dodged them all.

After suffering several consecutive heavy punches, the ancient dragon of the earth's core was completely wilted and lost the ability to resist. It was pinned to the ground and beaten by Su Yi.

“Too fierce!”

Shao Tianlei and others were once again shocked by the scene before them.

There was a crisp sound.

Su Yi suddenly used the [Tiger Heavenly Fist] and directly cracked the skull of the ancient earth dragon.

However, the defense of the ancient dragon of the earth's core was indeed strong. Even after suffering severe damage, it still did not die.

Su Yi then took out the [Obsidian Meteorite Sword], injected the power of space into it, and stabbed it into the fractured bone.

With a puff.

[Obsidian Meteor Sword] sank into the head of the ancient dragon at the center of the earth, and the power of space began to wreak havoc.

roar!

With a scream, the head of the ancient earth dragon exploded.

Su Yi leaped down and looked towards the ancient dragon in the center of the earth with narrowed eyes.

After the ancient dragon of the earth's core died, its huge body shattered into countless pieces, emitting a brilliant light.

When the light faded, a palm-sized purple seed was seen on the ground.

"It's actually seeds!" Su Yi looked surprised.

The seed in front of him was obviously not an ordinary seed, but was similar to the explosive fruit seed.

As for what kind it was, he had no idea.

But at this moment, the [Intelligent Chariot] reminded: "Su Yi, this should be the seed of the Tree of Life."

"What's the use?" Su Yi asked.

The name of the Tree of Life sounded a bit unusual, and it aroused his great interest.

The [Intelligent Chariot] explained: "When the Tree of Life matures, it will produce Life Spirit Liquid. The Life Spirit Liquid has the same function as the Shouxi Fruit, which can increase lifespan. In addition, you can also use the Life Spirit Liquid instead of the Shouxi Fruit to refine the Longevity Pill."

"nice one!"

Su Yi was extremely excited and quickly put the tree of life seed into his [Qiankun Ring].

Anything that can increase one's lifespan is hard to come by; even if it is just a seed, its value is self-evident.

Shao Tianlei and others stood quietly aside. Even when Su Yi put the things away again, they did not say a word, nor did they show any dissatisfaction.

Because they all knew that all the creatures in the formation were killed by Su Yi alone.

The things that were exposed should naturally belong to Su Yi.

When Su Yi and others walked out of the formation, the little boy couldn't wait to walk towards the last stone door.

Qiu Xing, who was standing alone, pondered for a moment, then gritted his teeth and walked towards Su Yi.

"Su Yi, if you save my life, I will give you everything I have."

Coming closer, Qiu Xing said bluntly.
