Passing through the nest inhabited by the top nightmare species, the treasure hunting dragon beast took Su Huan into a not deep and shallow rift.

The width and length of this rift valley is far inferior to that of the abyss where the rock rift dragon inhabited.

But the depth is even greater.

Moreover, there were countless various caves under the rift, and for a while, Su Huan followed behind the treasure hunting dragon beast and scurried around in the various caves.

I walked in the dim tunnels underground for more than an hour.

After the treasure hunting dragon beast signaled that it had arrived, Su Huan and his party finally stopped.

Passing through a narrow, dark and damp cavern, a powerful dragon power rushed towards him, and even Su Huan's current master-level spiritual strength was in turmoil.

What's more, Su Huan was still hiding in the shadow pocket of the shadow wombat at this time.

Long Wei even infiltrated it.

The strength of Longwei can be seen.

After the Treasure Hunter Beast confirmed that there was no danger through its senses, the shadow of the shadow wombat incarnation wandered in the darkness and crossed the tunnel to the source of the dragon's might.

At the end of the road is a very wide cave.

In the cave, it is no longer dim and lightless, but flashes with dazzling light, illuminating the whole cave as if it were day.

The source of light is also the source of Longwei.

A huge cone-shaped crystal stood in front of Su Huan's eyes.

Inside the yellow crystal, there is a light source that continuously glows, and it is these light sources that emit light.

"Dragon's Vein in the Center of the Earth!" Su Huan saw this huge crystal through the vision of the shadow wombat, and recognized the origin of this crystal, which was the dragon vein in the center of the earth.

The Earth's Core Dragon Vein is a mineral vein born deep underground rich in dragon energy, in the form of a luminous yellow crystal, which can have a beneficial effect on the dragon bloodline of the dragon race.

At the same time, it is also a valuable resource.

Just as Su Huan was about to take the Treasure Hunt Dragon Beast out of the shadow pocket, the Treasure Hunt Dragon Beast gave an early warning.

Su Huan hurriedly stopped.

The shadow wombat is even more vigilantly hiding behind the shadow of a stone, almost merging with the shadow, coupled with the effect of the secret medicine of the hidden breath, it is difficult for others to detect the existence of the shadow wombat.

In the midst of a rustling sound, several dangerous creatures with huge heads, sharp claws, walking on all fours, and gray scales all over their bodies, looked like some kind of earth dragon, and walked into the cave.

These earth dragons also dragged a lot of prey in.

Looks like it just came back from a hunt.

"Gray Cave Dragon!" Su Huan identified it and finally recognized the origin of the other party.

Gray Cave Earth Dragon, a not common elemental dragon, a special horror species.

The reason why they are not immediately recognizable is purely because the size and appearance of these Gray Cave Dragons are very different from the traditional Gray Cave Dragons.

Not only is the size several laps larger than the Gray Cave Earth Dragon in Su Huan's memory, but the breath on his body is clearly beyond the scope of the super-level horror species, at least reaching the level of the top-level horror species, and the Gray Cave Earth Dragon led by him is not weaker than the super horror species in the complete period.

After entering the cave, several gray cave earth dragons easily laid down their prey, and one by one they couldn't wait to get to the side of the geocentric dragon vein, greedily sucking up the mysterious energy emitted by the geocentric dragon vein that helped strengthen the dragon's bloodline.

The appearance of the Gray Cave Earth Dragon made Su Huan even more vigilant.

Although the Gray Cave Earth Dragon was completely inadequate for Su Huan, Su Huan did not dare to guarantee that there would be a stronger and even powerful existence that he could not handle.

Su Huan planned to observe first, and if it was sure that it was safe, he would consider whether to occupy this geocentric dragon vein, in order to prepare for the treasure hunting dragon beast to begin to transform into a dragon.

The shadow wombat hid for most of the day.

Su Huan also wasted most of his time in this cave.

Su Huan finally determined that this cave was really only occupied by this small gray cave earth dragon clan.

The entire clan was only seven or eight gray cave dragons.

"Treasure Hunter Dragon, looks like you're not bad luck." With a smile, he looked at the treasure hunting dragon beast path that couldn't wait.

"Energy Absorbing Tree Dragon, mark this place, and when the Treasure Hunter Dragon Beast finishes digesting the transformation secret elixir propotion, we will come here directly." Su Huan finally decided not to occupy this cave for the time being.

With the prohibition that the dojo cannot kill elemental shallow sea native species at will, Su Huan was unwilling to easily violate the law.

If it is just to expel this group of gray cave dragons, there is a great risk.

The Gray Cave Earth Dragon is not strong, but it does not mean that there are no powerful races nearby.

It's entirely possible that the Grey Cave Dragons will attract a stronger race.

In addition, the treasure hunting dragon beast had not yet completed the digestion of the secret medicine, so after weighing it again, Su Huan decided to wait.

The energy-absorbing tree dragon quickly marked the cavern's Void Anchor.

Then he took Su Huan and shuttled directly into the void and left the cave.

By the time Su Huan came to the ground, it was already the afternoon of the second day.

Su Huan took the pets to start the trial task again.

Time passed day by day.

Su Huan's trial mission is finally coming to an end.

The nightmare opponents defeated by Su Huan have surpassed Senior Sister Li Wushuang in both quantity and quality.

Since the Treasure Hunt Dragon Beast was also about to completely digest the transformation secret elixir prodrug, Su Huan decided to end the trial task and start the Treasure Hunt Dragon Beast's transformation dragon.

After the treasure hunting dragon beast completely digested the secret medicine, Su Huan took the pets to shuttle through the void of the energy-absorbing tree dragon, and directly came to the cave with such treasures as the geocentric dragon vein.

Through the shadow pocket, the treasure hunting dragon beast sensed the dragon vein in the center of the earth, and was very excited.

Although the Treasure Hunter Dragonmon is very salty for combat and training, it has an instinctive desire for transformation and evolution that every dangerous creature has.

At this time, the appearance of the treasure hunting dragon beast has changed greatly.

The yellowish-brown scales covered the whole body, and the size of the body did not change much, but it became very round, like a round ball.

Contrary to its round body, the claws of the Treasure Hunter Dragon Beast are extremely sharp.

And the horn on the forehead of the treasure hunting dragon beast has also grown a bit, and now it is close to a palm's length, and it is also flashing with a sharp cold light.

Su Huan took the treasure hunting dragon beast out of the shadow pocket.

Su Huan's sudden appearance naturally surprised the gray cave dragons in the cave.

However, Su Huan didn't mean to say sorry, and after scanning the size of the cave and making sure that it could accommodate the Rock Ruin Dragon, Su Huan directly summoned the Rock Ruin Dragon.

"Ruin Dragons, banish them!"

Su Huan did not kill the original owners of this geocentric dragon vein, the poor gray cave earth dragons, but chose to expel them.

In this way, even if they return after being expelled, the Treasure Hunter Dragon Beast must have completed its transformation into a dragon.
