Zhou Heyan's expression was slightly stunned.

"Apprentice, I can still roughly see the limit of your Rock Ruin Dragon's strength, the defense is indeed extremely strong, and even my Earth Splitting Ape King may not be sure to break the defense and defeat it, but I tell you the truth, it can't withstand the attack of the Rock Cracking Dragon for the time being."

"That guy, even the Black Sin Behemoth can't resist the attack."

Zhou Hesheng was afraid that Su Huan would be eager for quick success, so he persuaded: "Apprentice, don't be in a hurry to subdue the Rock Crack Dragon, we will make plans when your Rock Ruin Dragon is cultivated." ”

Su Huan saw the teacher's thoughts and explained: "Teacher, what I'm talking about is naturally not now, but after the strength of the Yanxu Dragon will be improved a little more." ”

"If that's the case, I'm still sure to defeat the Rock Splitting Dragon."

"After all, no matter how strong its defense is, it will be difficult to block the all-out onslaught of all the pets of the division." Zhou He cut the railway.

After the master and apprentice chatted for a while, Su Huan said goodbye and left.

Back in the room, Su Huan began to think about improving the strength of the Yanxu Dragon again.

"If you want to withstand the attack of the advanced nightmare species at the end of your growth head-on, the Rock Ruin Dragon must at least be promoted to maturity."

"But with a race as strong as the Rock Ruins Dragon, it is very difficult to cross two stages of growth in a short period of time."

"However, if you cross a level and reach the end of growth, it is still possible to achieve it in a short period of time, as long as the cultivation method is appropriate."

"Spanning a level, it is naturally far from withstanding the attack of the Rock Cracking Dragon, but Su Huan has other hole cards."

"His hole card is the ubiquitous power of returning to the ruins in Black Ruins City."

"Those ruin power are well used, and they can make a lot of secret medicines suitable for the rock ruin dragon, and the power of some of the secret medicines is even greater, the rock ruin dragon that has been promoted to the end of growth, plus the secret medicine that temporarily increases defense, should be able to withstand the attack of the rock crack dragon, right?" Su Huan estimated in his heart.

"If the teacher's Moon Power Dragon Bear or Ice Shock Dragon Lion can also be improved in the growth stage, then the grasp of dealing with the Rock Crack Dragon will be even more sufficient."

"Tomorrow, I will send the most suitable cultivation method and perfect-level food formula for the teacher's two pets to the teacher."

"Aim to reach the goal within a month."

After making up his mind, Su Huan began the strength improvement plan of the Yanxu Dragon.

I want to improve the strength of the Ruin Dragon as quickly as possible.

Two conditions must be met.

One is nurturing.

Cultivation includes, food, secret recipes, secret medicines and other external factors.

The other is training.

The training includes various types of skill training, as well as combat training.

In terms of cultivation, what Su Huan can provide is definitely the top.

As for training, the most effective is actual combat training.

If you want to make the Rock Ruin Dragon, who has just entered the late stage of growth, grow to the end of growth within a month, there is no other way than high-intensity actual combat training.

And it must also be targeted combat training, so that the Yanxu Dragon can fight with all kinds of different opponents, and it is far from enough to rely on the teacher's pet as an opponent.

With the strength level of the Rock Ruins Dragon, it is also a trouble to find a suitable opponent.

The huge Black Light Castle, except for the teacher, the current pets of other pilots, in the face of the rock ruin dragon, are all hammered, and they can't have a training effect at all.

As for finding a master in another settlement to fight?

Again, it's a bit out of place.

The masters who can have super terrifying combat power in the Gray Wilderness Wasteland are undoubtedly at the level of a party leader, how can they easily accept challenges and battles.

"Could it be that you want to echo Thunder Fortress City first?" Su Huan was a little helpless.

Suddenly, there was a loneliness that it was difficult to find an opponent.

But Su Huan suddenly had a flash of inspiration, since the powerful masters of those settlements couldn't challenge at will, there shouldn't be any problem for the wild and dangerous creatures in the wild to challenge, right?

As far as Su Huan knew, there were still quite a few powerful wild horror species in the entire Gray Wilderness Wasteland.

Even the Rock Rift Valley has a high-level Nightmare Rock Rift Dragon, let alone anywhere else!

With this thought, Su Huan couldn't let go.

He immediately went to the Blacklight Castle Library and the Confidential Archives, and began to dig through the records of the distribution of the Grey Wilderness Wasteland's overlord-level powerful creatures.

Sure enough, the harvest was quite fruitful.

In the entire Gray Wilderness, there are no less than thirty super horror species and secondary nightmare species recorded in Black Light Castle.

This is only recorded in books, and Su Huan believes that there must be more detailed distribution of overlord creatures that have not been recorded on paper.

When you're going to deliver the cultivation recipe tomorrow, ask the teacher by the way.

Su Huan now transcribes the distribution of more than 30 places.

And preliminarily formulated a road map, preparing to get a more detailed distribution from the teacher tomorrow, and start to follow the route, let the Yanxu Dragons go to the door one by one to challenge the battle.

In order to grow to the end of growth within a month.

Immediately afterwards, Su Huan began to prepare before departure.

First of all, the logistical support required for this special combat training for the promotion of the Rock Ruins Dragon must be sufficient.

Although the energy-absorbing tree dragon has been able to provide food for the ruin dragon.

But some secret medicines and secret recipes still need to be prepared by Su Huan.

"Core Potion", "Ruins Secret Elixir", "Withered Poison" and other secret medicines were configured one by one under Su Huan's hands.

Many of the ingredients of these secret elixirs have already exceeded the level of the horror species, so the energy-absorbing tree dragon does not have the ability to parse, and can only be configured manually.

It's something that can't be helped.

When everything was in place, the time had come to the next day.

The secret recipes and food recipes that Su Huan prepared to hand over to the teacher about the cultivation of pets had already filled half of the notebook.

The teacher took the note, only glanced at it a few times, and his eyes were filled with shock.

"These, these things?" Zhou He's vision is undoubtedly extremely high, and he can see the value of these materials almost at a glance, which can definitely make a qualitative leap in the cultivation of his pets.

If it is said that according to his cultivation method, it is a trot to improve, then the things on this note are soaring into the sky.

However, Zhou He didn't ask much, he was not surprised that Su Huan could take out these things from time to time.

It didn't take long for Su Huan to get the distribution of more than twenty Gray Wilderness Wasteland Overlord-level dangerous creatures suitable for acting as the opponent of the Rock Ruin Dragon from his teacher, and left happily.

At present, the distribution of overlord creatures that he has mastered has reached as many as fifty or sixty.

It's time to start the Rock Ruin Dragon's Challenge Training.

These are found throughout the Grey Wasteland.

Of course, the distribution of these overlord creatures has not set foot in the four dangerous places.

Instead, they are confined to the interior of the Grey Wasteland.

After all, the danger of the four dangerous places is beyond the scope that Su Huan can deal with.

Su Huan spent half a day working hard to make a sort according to the strength of each overlord creature and formulate a route.

With the prepared road map and the secret medicine needed by the Rock Ruin Dragon, as well as a group of pets, Su Huan walked out of the black light settlement.
