It is said that all dragons will have a reverse scale on their body.

This reverse scale, simply put, is a special scale that grows in the opposite direction from other scales.

For every dragon, there is only one, and there will definitely be one.

Why this happened, Zhao Feng didn't want to explore, he only knew now that the reverse scale was his chance to kill the ancient demon dragon.

"Li Lei, you jump behind him, the reverse scale of this ancient demon dragon is on his back, if you find the reverse scale, you can kill this ancient demon dragon!"

Zhao Feng shouted and ordered directly at Li Lei and the others.

At this time, the Elder Demon Dragon was already in a state of rage.

Of course, whoever sleeps well is woken up by someone with a knife, and he is probably furious.

The ancient demon dragon's whole body was bubbling with purple-red flames, and the dragon breath in his mouth was constantly spewing out.

This dragon's breath is the ancient demon dragon, and it is also the basic attack method of every dragon clan, which does not require much preparation time and does not consume much.

He could even spit on as long as he wanted to.

However, don't think that this unconsumed dragon breath can be weak.

At this time, around the Ancient Demon Dragon, those poor lava and fire trees were also directly melted by the dragon's breath with a terrifying temperature.

The dragon breath of this ancient demon dragon is even several times hotter than the hottest magma!

Li Lei and the others immediately understood.

Slaying the dragon first to find the reverse scales, this can be regarded as common sense.

However, the reverse scales of each dragon are undoubtedly the core of their defense, and they will try their best to hide the existence, under normal circumstances, it is not easy to know the location of the dragon reverse scales.

Unexpectedly, Zhao Feng actually knew the location of this ancient demon dragon reverse scale.

This is undoubtedly the light of day for the four of them again.

"Kill!"

The four of them lunged again at the door.

And Zhao Feng could only watch helplessly.

In fact, it is estimated that even if the system is intact now, Zhao Feng is not qualified to be involved in such a battle at all.

Therefore, from waiting, Zhao Feng can't do anything else.

The battle lasted for three days and three nights.

In fact, how could the Elder Demon Dragon not know the importance of his own scales?

Therefore, Li Lei and others couldn't find a chance to make a move at all.

However, as the battle progressed, the four of them became more skilled in cooperating.

Finally, the Ancient Demon Dragon was just a small negligence, and it gave Li Lei and the others a chance!

"It's now, quick, shoot!"

I saw that Li Lei suddenly threw Bai Po out, and when Bai Po was in mid-air, he sacrificed his strongest killing move and flew straight to the back of the ancient demon dragon.

"Whew!"

The Elder Demon Dragon, who was attacking the other person, sensed Bai Po's intentions and turned around suddenly, trying to stop Bai Po.

However, as soon as he turned his head, the man he had suppressed before also rushed towards the back of the Elder Demon Dragon.

......

Time, as if frozen at this moment, Zhao Feng stared at the battlefield deadly, his fists were clenched even tighter, whether he could defeat the ancient demon dragon or not, it depended on this blow.

If it fails, then Zhao Feng can only be trapped here, but if it succeeds, Zhao Feng will get huge benefits!

It seems to be in the blink of an eye, and it seems to have gone through thousands of years!

With a huge roar, the Ancient Demon Dragon was the center, and suddenly, a huge and incomparable wave of qi erupted.

Blazing air waves!

That's the last madness of the ancient demon dragon, how can it not be strong!

"Not good!"

Zhao Feng's figure suddenly retreated again and again, this wave of qi was too powerful, it could be said that it was enough to break Zhao Feng's bones.

The Dry Bone Sword came out, all blocking in front of Zhao Feng, and one by one the defensive artifacts were also thrown out by Zhao Feng.

At the same time, Zhao Feng retreated with all his might.

But, even so, that wave of qi still hit Zhao Feng.

"Poof!"

Zhao Feng spit out a mouthful of blood!

"Damn, it's so strong, I've been hiding in the distance, and I've resisted it with a dry bone sword and countless defensive artifacts, and I've been so seriously injured. This Ancient Demon Dragon is really too strong!"

Zhao Feng said to himself helplessly, at this time, he already knew that he was afraid that Li Lei and the others were already unlucky!

Sure enough, when Zhao Feng flew to the battle position again, where could he still see the corpses of the four people, and those four people were directly smashed by the final blow of the Ancient Demon Dragon.

"Hey, after all, the four of you died for me, and I, Zhao Feng, will not lose you, so let me resurrect you for you!"

Zhao Feng had the fragment of the godhead of those four people in his hand, which was equivalent to the imprint of life, and with this fragment of godhead, he would be able to resurrect these four people.

However, the cost is extremely high.

After all, what Zhao Feng had in his hands was just a small fragment.

At this time, the Ancient Demon Dragon and the four of them had already died together, and Zhao Feng naturally would not waste it, and directly put the corpse of the Ancient Demon Dragon into the exchange space.

This ancient demon dragon is full of treasures, it can be said that whether it is upgraded by Zhao Feng himself or used to repair the system, it is definitely a good thing, of course, before that, it is necessary to deal with the guard god in front of him first.

From the moment the Ancient Demon Dragon died, this gatekeeper had already appeared in front of Zhao Feng.

"Hehe, boy, yes, even the ancient demon dragon was killed by you, not bad, yes, here you go, this is your reward, you can leave. ”

The gatekeeper didn't seem to care about how Zhao Feng passed at all, in his eyes, as long as the ancient demon dragon died, then even if Zhao Feng passed the trial.

With the words of the guarding god, Zhao Feng's figure moved again, and he was directly teleported away again.

Of course, Zhao Feng didn't mind.

When he came outside and was sure that there was no danger, he began to process his harvest.

He was first rewarded by the gatekeeper god, but when he took out the thing, he was stunned.

It's an egg!

"Ding! Congratulations, get a special treasure, the Elder Demon Dragon Egg, congratulations, please note, the Elder Demon Dragon, but you can use the rest of the special materials, special things. ”

Sure enough, Zhao Feng nodded, and when he saw this egg, Zhao Feng's first reaction was that it was estimated that he was going to get a new thing this time.

Sure enough, along with the prompts of the system, it undoubtedly proved that Zhao Feng's guess was correct.

However, now Zhao Feng didn't have the rest of the materials, so this Ancient Demon Dragon Egg could only be put first.

This ancient magic dragon can be a total of three things.

The first is the Ancient Demon Dragon, which is not so much a fusion as a catalyst, because this egg is the Ancient Demon Dragon's, of course, this is undoubtedly the least resources required, and at the same time, the combat effectiveness is also the lowest.

The first thing Zhao Feng ruled out was it.
