After swallowing ** blood, the giant python did not burst its body as Xu Feng imagined, but appeared four bulges in its abdomen, and as time went by, the four bulges became more and more obvious, and they were four legs.

"It's here, the dragon?" Xu Feng's heart became excited.

It is very difficult for such a giant python to grow and evolve into a dragon, first of all, it has to grow limbs, then it has to grow dragon horns, and finally it becomes a giant dragon.

The long python let out a painful roar, and its voice, from the original hissing of snakes, gradually became thick, with a hint of dragon might.

In the process of the limbs being fully formed, the breath of the giant python became very unstable, one would break through the seven stars and become the existence of the eight-star strength, and the other would fall down, still the breath of the seven stars.

The giant python kept rolling, crushing countless huge rocks, and the tiny scales on its body began to fall off in large pieces, and the thick and wide scales began to slowly cover its entire body, and the originally oval head also became square.

This physical change made the python extremely painful.

Feeling the instability of the giant python's breath, looking at the tiny scales that fell off its body, and the thick scales that had not yet fully formed, Xu Feng suddenly had a crazy and bold thought in his heart.

"Kill it now!"

Suddenly, hundreds of seven-star insect soldiers appeared around Xu Feng's body;

At this time, almost all the strength of the giant python's body was resisting the power of evolution conceived in the blood of the black dragon's essence, and it was about to succeed, the four long legs were about to take shape, and three thick toes could be faintly seen, slowly poking their heads out.

At this time, it is the most vulnerable time for the python and the lowest resistance of the body;

Pedal Pedal Pedal ~

A series of thin and rapid steps sounded, and hundreds of insect soldiers swarmed and pounced on the python;

The sharp bone blade easily pierced the newly formed scales, tore through the python's skin, and cut into its flesh and blood;

Blood splattered out, and the python let out a terrible roar, and its body began to writhe wildly;

One by one, the insect soldiers were crushed under the body of the giant python, and more were directly hit by the giant python and thrown out;

Click, click~

The sound of the python's bones breaking, the pain and the threat of death, made the python even more violent, a low roar came from the mouth, and the majestic power emanated from it, with a faint dragon might;

This kind of dragon power only made the movements of the insect soldiers stagnate slightly, and the attack did not stop, and hundreds of points of damage came out from the top of the giant python's head one by one;

If you want to rely on the advantage of numbers, it is impossible to kill an eight-star elite-level boss with a seven-star insect soldier;

Xu Feng's palms were full of sweat, nervously looking at the battle in the distance, one by one insect soldiers appeared beside him, and pounced towards the giant python, the soul energy that had just been slightly filled was rapidly decreasing with the battle, like a flood that had discharged the floodgates;

If it weren't for the fact that the aura of the giant python was still chaotic at this time, Xu Feng would probably turn around and leave immediately, even if he had sacrificed the soul energy of hundreds of insect soldiers, he would not stop;

It's just that the current giant python has not yet evolved into an eight-star elite-level boss, and Xu Feng still has a chance;

Puff~Puff~

There were more and more wounds on the giant python's body, and its aura gradually weakened, and the anger in its eyes, if it became substantial, could burn Xu Feng and all his insect soldiers;

It's a pity that the eyes of the giant python can't cause Xu Feng the slightest damage;

In the end, the giant python still did not escape the fate of being killed, but unfortunately, because he did not succeed in advancing to the eighth star, what Xu Feng obtained was still only a red blood crystal core;

Xu Feng now wanted to know what kind of crystal nucleus it would drop if he killed a monster with eight-star strength;

Time passed, Xu Feng kept moving towards the source of the Noer River, and the huge black dragon figure had been haunting Xu Feng's heart;

This is the first time Xu Feng has seen an existence whose strength surpasses that of the Nine Stars, even if it is a black dragon that is close to death, it is also Xu Feng at this time, an irresistible existence;

You must know that the lifespan of the dragon clan is very long, even if the dragon clan enters the death period, there are several years, or even more than ten years of life, if you want the black dragon to die naturally like this, Xu Feng definitely can't afford to wait;

But the long sword on the back of the black dragon gave Xu Feng a glimmer of hope, it was a long sword that looked inconspicuous, and it pierced into the body of the black dragon obliquely, you know, beyond the existence of the nine stars, the body has already become like steel and iron, and ordinary nine-star quality weapons can't even pierce the scales on the surface of the black dragon's body;

Along the way, Xu Feng's eight hundred jade crystal nuclei have already been collected enough, and the red blood crystal nucleus has only collected almost half of it now, seeing that two transfer tasks have been completed, Xu Feng faces the black dragon, at least has the ability to leave at any time, but in this way, it is not possible to complete all three transfer tasks;

Xu Feng climbed over a peak, and looking into the distance, a strange and strange building was floating in the air above the jungle in the distance, attracting Xu Feng's attention;

The outermost layer of the building is a wall more than ten meters high, all of which are made up of huge cyan rocks one meter square, which seem to have undergone countless war erosions, full of desolation, and the traces of being hit by boulders are all over the wall, Xu Feng even saw a huge crack, extending from the root of the wall to the top of the wall;

Floating City?

Xu Feng was slightly stunned, such a scene can only be seen on a magic-themed alien planet, Xu Feng's sacrificial city is the gateway to such a world, where such floating cities abound, but in such an ancient world, the sudden appearance of a floating city still made Xu Feng feel a little surprised;

System: You've discovered Dragon's Grave City!

System: You've discovered a mystery unique to this world!

System: There will be unexpected dangers when you go to the Dragon Tomb City, so decide your next step carefully!

System: There will be unexpected treasures in the Dragon's Tomb City, where you will get a lot of riches!

A series of four system prompts appeared in front of Xu Feng's eyes, making Xu Feng's eyes light up;

Crisis and opportunity coexist, not to mention, this involves the unique mystery of the world, which makes Xu Feng how to give up;

However, before that, Xu Feng still decided to complete the third transfer task first, and then set foot on the Dragon Tomb City, after all, Xu Feng had seen with his own eyes that a black dragon that surpassed the existence of the Nine Stars flew towards here, Xu Feng believed that the ultimate goal of that black dragon must be this Dragon Tomb City!
