Time passed day by day.

The climate in the Grey Wasteland is starting to cool.

Half a month has passed since the challenge of the Rock Ruin Dragon.

Within half a month, there were no less than twenty Super Horror level opponents who had lost in its hands.

During this period, the Yanxu Dragon also suffered several defeats.

However, even if it is defeated, the opponent will not have the slightest defense against the Rock Ruins Dragon.

In the end, it was a tie, and the Yanxu Dragon took the initiative to retreat.

The defense and difficulty of the Rock Ruin Dragon is where Su Huan's confidence lies in daring to take it around to challenge.

Even if it is a secondary nightmare species, I am afraid that it will be a headache in the face of the defense of the Rock Ruins Dragon.

In the past ten days, the strength of the Rock Ruin Dragon has also increased rapidly in the secret medicine and perfect-level food recipe and a large amount of actual combat training.

At this point, we are very close to the end of our growth.

The most significant improvement is in the cultivation of energy skills, and the Rock Ruin Dragon has mastered the first level 8 civilization ability.

Destroy Aurora's Level 8 Civilized "Death Light" ability.

The "Death Light" ability is not only amazingly destructive, but also has a lethal effect, with a chance to kill the target hit, but it only has a high probability of being a target whose strength is weaker than itself, and the strength is equal to or even close to one's opponent, and the probability of success is already close to zero.

The mastery of the "Death Light" ability has greatly increased the aggressiveness and lethality of the Rock Ruin Dragon.

After the end of a fierce battle, Su Huan was summarizing the gains and losses after the battle with the Yanxu Dragon as usual, and analyzing the shortcomings in the battle process.

After summarizing, Su Huan did not let the Yanxu Dragon rest and recover as usual, but continued to analyze the next battle.

The battle challenge routes of the Yanxu Dragon were all arranged by Su Huan in advance.

For each opponent, Su Huan also formulated different battle modes along the way.

But the next battle was indeed improvised.

Su Huan attaches great importance to this battle.

The importance of nature is not only the battle itself, but the goal of this challenge and a resource mastered by the Rock Ruin Dragon.

Su Huan didn't know about that kind of resource, and even this battle object was not within the scope of Su Huan's planned route.

Because it is a nightmare species, even though it is only a nightmare species at the end of its growth, its strength will never be weaker than that of the teacher's Ice Shock Dragon Lion.

Although Su Huan was aware of its existence, he had no plans to challenge it for the time being, because choosing this kind of opponent to fight was actually a bit too reluctant for the Yanxu Dragon.

But the unexpected discovery of the treasure hunting dragon beast made Su Huan know a resource in his hands, but it made Su Huan's heart pound.

"Wraith Primordial Fire!"

The Spectre Primordial Fire is a special type of strange flame, this flame has the property of burning permanently, and it is difficult to extinguish it by ordinary means.

The effect of the Ghost Primordial Fire is only to breed the birth of ghost-type dangerous creatures and accelerate the growth rate of low-level ghost-type dangerous species, and the effect of the horror level is somewhat lacking.

Su Huan's fancy is naturally not the use of the ghost original fire.

Aside from an ice cave shadow that had become a split brain, he didn't have any other ghost pets.

The reason why Su Huan is so interested in the Ghost Primordial Fire is because the Spectral Primordial Fire has another use besides its own function.

Spectral Fire can be used as one of the ingredients used to craft a type called "Living Flame".

And the original fire of life, this is a top-level resource that can accelerate the leap of the life level of the pet, that is, the improvement of the growth stage, and even improve the success rate of the transformation and evolution of the pet.

And it can be reused over and over again.

In the old dragon classics, there was a specific way to fuse the original fire of life.

A total of three different types of primordial fire are required as the primary material, as well as a large number of auxiliary materials, in order to fuse.

Wraith Primordial Fire is one of them.

The original fire is a treasure of heaven and earth, and only heaven and earth can be born naturally, and cannot be artificially made, so it is extremely rare.

Although he knew that the possibility of gathering the three original fires was not high, Su Huan was still very interested.

If you can really synthesize the Life Primordial Fire, the cultivation speed of the pet will be raised to a new level.

"According to the records of the old dragon codex, the original fire of life was first born sixty years later."

"As soon as it came out, it made the research institute that invented the original fire of life hot, and made countless profits in just a few years."

"A few years later, the secret recipe for the synthesis of the original fire of life was leaked, which caused a wave in the master world."

"Rare synthetic raw materials such as the Ghost Primordial Fire have been robbed even more like crazy, and their value has jumped countless times."

"The Primordial Fire of Life has become a treasure that ordinary professional-level pilots, and even master-level pilots, can't hope for."

"Now the life primordial fire has not yet been born, so I can be regarded as taking the lead, through the massive resources of the thunder fortress city, the effect of the three respective abilities is not outstanding, but after fusing into the life primordial fire, the main material of the primordial fire with the ability to defy the sky, it should not be too difficult."

"It's just that if you want to get the ghost original fire, you have to fight that difficult guy first." Su Huan sighed in his heart while arranging the next tactics for the Yanxu Dragon.

That nightmare species that also has a ghost primordial fire is not easy to deal with.

Fortunately, the ghost system, which is the form of an energy body, and unlike the formless demon that has a void system, the Burning Ghost happens to be restrained by the Rock Ruins Dragon's Rock Ruins field.

Otherwise, Su Huan didn't plan to immediately let the Rock Ruin Dragon challenge the Burning Ghost at the end of its growth.

The Burning Ghost is a secondary nightmare species of ghosts, fire, and spirits, and has extremely strong fire and ghost abilities, and its spiritual talent is not weak, and it is not a weak person among the secondary nightmare species.

If you fight against the Ice Shock Dragon and Lion who are at the end of the growth period with the teacher, the victory and defeat can be five or five.

However, whether it is the ghost type or the fire type, they are all restrained by the Rock Ruin Dragon, so the Rock Ruin Dragon still has a chance to win.

But if the Yanxu Dragon wants to win steadily, it also needs certain targeted tactics, especially for the spiritual ability.

Although the Rock Ruin Dragon's Rock Ruin Field can even weaken its spiritual ability, in the final analysis, the Rock Ruin Dragon's ability to resist the spiritual system is still relatively weak.

Even the ability to barren stomach bags, the level of defense against spiritual attacks is also greatly reduced.

However, Su Huanshan people have their own clever plans.

Horrors aren't just for masters.

His Silent Bracelet happens to be useful for defensive spirits and psychic abilities.

In battle, it is just enough to let the ruin dragon wear it first.

In addition, as a master who is involved in the spiritual bond with the Rock Ruin Dragon, Su Huan can also awaken and help the Rock Ruin Dragon when it is invaded by hallucinogenic and control abilities.

to resist such abilities.

After some tactical planning, it was getting late.

Su Huan immediately summoned the energy-absorbing tree dragon to create food fruits, and fed all the pets, so that everyone could rest early.

In particular, he told the Yanxu Dragon to rest well and recuperate, and there will be a big battle tomorrow, which is related to whether or not he can successfully get the Ghost Primordial Fire.

As for whether the Rock Ruin Dragon would be injured by that burning ghost, Su Huan was not worried.

If you want to injure or even severely damage the Rock Ruins Dragon, I am afraid that you must at least complete the secondary nightmare species, and the secondary nightmare species of the mature stage may not be able to do it.

After dozens of battles, Su Huan has a certain understanding of the limit of the defense of the Yanxu Dragon.
