Taking advantage of the afterglow of the setting sun, Xue Yi ran towards the hill that the Thunder Emperor Lei Yutian pointed to. At this time, beside him, on the left was a purple electric Tyrannosaurus rex waving its wings, and on the right was a skeletal dragon running fast.

Strange to say, the purple electric Tyrannosaurus rex wanted to attack all the living creatures it saw, including Xue Yi. But when it saw the skeleton dragon, it did not attack, but appeared very calm.

The hill was not far away, and one man and two dragons were soon there.

When the skeleton dragon stopped at the edge of the hillock and felt it for a moment, its eyes were full of fire, and it was obviously extremely excited, and the soul said, "This is it, that's right, the dragon!"

Xue Yi immediately took out a dragon-toothed dagger and began to excavate this hillock.

In fact, he had several ways to blast the hillock apart very easily, but those methods were too destructive, and he was afraid of damaging the wing bones of the Immortal Dragon.

However, even if he used a dagger to dig, Xue Yi's speed was not slow. In less than ten minutes, he had dug up the entire hillock with a diameter of more than one meter.

What appeared in front of Xue Yi's eyes was the wreckage of an inexhaustible dragon. The tail bone had been broken into several pieces, a leg bone was missing, and a hole appeared in the skull.

Thankfully, the bones of its wings are still intact.

Xue Yi carefully lifted the wing bones out and wiped the dirt off them. Then he took out the medicine box and said to the skeleton dragon, "Boss Dragon, it's okay now." ”

At this time, the skeleton dragon gathered all the flames on its body into its body, and the white bones of the forest were revealed again.

Xue Yi hung the one-meter-long left wing hook on the skeleton dragon, and then hung the right wing bone hook on it. Then use the steel nails you carry with you to secure it so that it doesn't fall off. But at the same time, it cannot be nailed, so that it cannot move.

As a sixth-level dragon doctor, Xue Yi could be said to be handy at doing this, and he completed it in just five minutes.

After doing all this, Xue Yi took two steps back, looked at the skeleton dragon, and couldn't help but nodded: "Perfect, too perfect." ”

At this time, the skeleton dragon released the dragon fire, first covering its entire body, and then spreading towards its wings.

Since there was not much dragon fire in the skeleton dragon's body, the area covered now had increased, making the dragon fire on its body even thinner.

Soon, the dragon fire completely covered the skeleton dragon's entire body.

By this time, the sunset had completely sunk into the ground, and the sky began to slowly darken.

Xue Yi anxiously glanced at the surrounding mountains and said to the skeleton dragon, "Dragon Boss, hurry, otherwise we will be attacked by those dragon souls again." ”

As he spoke, two small whirlpools appeared on the skeleton dragon's wings. Between the whirlpools, the fire attribute elements between the surrounding heaven and earth were absorbed by it at an extremely fast speed, transforming into dragon fire. Soon, the dragon fire became rich again, covering the skeleton dragon's whole body, and the bones on the skeleton dragon's body were no longer visible.

The speed at which the skull dragon produced dragon power was many times faster than before. According to Xue Yi's estimates, it was even twice as fast as the strongest fire-type dragon clan's Burning Flame Dragon.

"If you don't strive for a dragon, you deserve to be a dragon!" Xue Yi clenched his hands, his eyes shining with excitement.

Under the cover of flames, the skeleton dragon suddenly roared excitedly: "Roar-"

It spreads its wings, and the wings covered in flames look very visually striking.

Whew――

With a flap of the wings, it soars into the air. It seems that not only does it produce dragon power faster than the Flame Dragon, but it also flies extremely fast. Although it can't reach the ** speed of the purple electric Tyrannosaurus rex, it is much faster than the ordinary fire dragon clan.

The skeletal dragon flew through the sky, dragging a long tail flame in the air and falling to the ground.

It looks like the skeleton dragon is quite happy with his wings.

Xue Yi seized the time and pressed the body of the skeleton dragon with both hands to absorb the power of the fire attribute dragon.

Five minutes later, it was completely dark, and the first soul dragon in the distance had risen up.

Xue Yi also stopped absorbing dragon power, and the fire attribute dragon power in his body had reached a saturated state. The soul looked inward, and saw that in his chest, behind the three purple points of light, there were four fiery red points of light.

Xue Yi was overjoyed in his heart, and pressed the body of the purple electric Tyrannosaurus Rex again, and after a while, the purple light spots also increased to four.

Level 4 Dragoon Attendant!

Unexpectedly, in just over ten days, he was promoted to another level.

In fact, a few days ago, Xue Yi had already felt that he was going to upgrade in the power grid of the outside world, but at that time, he felt that his physique was not enough to fully withstand the impact of the dragon power of the fourth-level dragon rider attendant, so he was not in a hurry to upgrade.

Now, after a few more days, the impact in the power grid, the impact in the electric column, and the repeated battles in the ancient battlefield, now the skeleton dragon has wings and has evolved from a juvenile dragon to a juvenile dragon. All of this added up to be a matter of course, allowing Xue Yi to complete the upgrade unconsciously.

At this time, four or five dragon souls had risen in the sky, and they had also discovered Xue Yi and the two dragons.

roared and pounced on Xue Yi.

At this time, the skeleton dragon directly spat out a mouthful of flames and attacked a giant dragon soul.

Not to be outdone, the purple electric Tyrannosaurus rex also spat out a mouthful of lightning and attacked the dragon's soul.

A flame and a bolt of lightning inadvertently converged in the air.

Boom -

A huge explosion was generated in the air, and a ball of energy formed by fire and electricity with a diameter of more than three meters suddenly exploded. A shockwave visible to the naked eye radiated three hundred and sixty degrees to the surroundings, and although the surrounding dragons were in a soul state, under the impact of this shockwave, they were also washed away by the black mist, and they were almost wiped out.

That soul dragon directly withstood all the explosions, and the black mist instantly became extremely thin.

Xue Yi was pressed by the shock wave just now and lay on the ground, and seeing that there was an opportunity, he hurriedly jumped up, took out the bloodthirsty sword from the space, jumped up, and swung towards the black mist that had become extremely thin.

The bloodthirsty sword was full of red light, and a huge suction force was generated, sucking the black mist into it in a moment.

Through Xue Yi's induction into the sword body, he knew that after the black mist was sucked in, it was compressed and turned into a walnut-sized ball of light. Because Xue Yi's soul had reached a saturated state and could no longer absorb other souls, and this was a dragon soul, which was not suitable for Xue Yi to absorb, he did not absorb this light cluster.

After a few moments, the soul light began to dissipate, turning into a part of the sword body.

The surrounding dragons were all shocked when they saw that the soul dragon was destroyed, and immediately scattered and fled. Although they are not conscious, they are sensitive to danger.

Seeing that the crisis was resolved, Xue Yi immediately ran towards the towering Lei Jiaomu in the center of the grassland.

Now that he has become a level 4 dragoon attendant, his speed has increased by a few points. One leap is five meters.

The distance of more than 20 miles took 10 minutes.

When he arrived at the towering thunder coke wood, Xue Yi operated the thunder attribute dragon power in his right hand and entered the huge ancient character "Li" on the towering thunder scorched wood.

On the towering thunder scorched wood, the purple light is flourishing.

Moments later, Reggio turned into a massive purple gate.

Xue Yi and the Purple Electric Tyrannosaurus Rex Skeleton Dragon entered the city gate, only to feel a flash of light in front of them, and they appeared in the round platform. Behind it was the small Reggio tree from the outside.

Xue Yi looked at the black lock in the distance, and the black lock was already able to stand up and walk around at this time. He tried to get close to Reggyo, but lightning struck him, preventing him from getting closer.

Xue Yi came to the Black Lock and took the Black Lock out of the range of Lei Jiaomu.

The look of worry in the black keyeyes was gone, replaced by joy.

At this time, in the fog more than twenty meters away, several fog demons screamed.

Xue Yi looked at the fog demons, smiled lazily, and said to the black lock: "You wait here, I'll save Ding Li and Wu Yingzi." ”
