Only some of the materials in the Inner Fort Warehouse must be exchanged for contribution points, and most of the materials can still be exchanged through the steel gram.

All materials in the castle vault located below the main castle must be converted with contribution points.

Last time, Su Huan was able to directly select three materials from it, but he still got the teacher's permission, and under the personal leadership of the chief manager, he didn't use the contribution points.

If someone else wants to take something out of the castle's vault, they must contribute absolutely nothing.

Otherwise, those evil eye monitors entrenched in the sky above the vault will not care who you are, but will directly call the police to call the Black Light Guards and even the Castle Guard.

This time, Su Huan had a huge amount of nearly 20,000 contributions.

Walking into the castle's vault, it was full of confidence and confidence.

As for the materials he exchanged last time, in fact, they added up to less than 10,000 contribution points.

This time, he made up his mind that he must go through all the treasures in the castle's vault.

First of all, he first scooped up the sound wind stone in his hand with ease.

Only then was the treasure hunter dragon beast released and began to pick things.

Last time, the Treasure Hunt Dragonmon only found the Sound Wind Stone in this vault.

However, this does not mean that none of the other Metamorphosis material vaults of the Dragon Snake Lizard do not exist.

Because at that time, Su Huan didn't know the transformation path of the dragon snake lizard and the materials required.

It is still in the ruins of the Blood Forest that the dragon snake lizard broke through the unsealed information of the old dragon code in the growth stage, which contains the way for the dragon snake lizard to transform into a wind thunder dragon snake.

This time, when Su Huan knew the specific materials, he first asked the treasure hunting dragon beast to search for them according to the specific materials.

But this time I didn't have the good luck of last time.

Except for the sound wind stone, the dragon, snake, and lizard did not find any other metamorphosis materials.

Since the main materials of the dragon snake lizard have not been found, it is naturally impossible to have the materials for the energy-absorbing tree to turn the dragon into an energy-absorbing tree dragon, and there is no need to even look for it.

Among the five materials of the Energy Absorbing Tree Transformation Dragon, high-purity energy crystals will not be placed in the secret vault, while the remaining four are dragon bloodline crystals, and naturally there is no possibility of them in the secret vault.

If anything, the Treasure Hunter didn't even need to go to the Blood Forest Ruins to complete the dragon transformation ceremony, and could directly turn into a dragon treasure hunting dragon beast through the crystallization of the dragonborn bloodline in the secret vault.

Su Huan was not much disappointed.

After all, whether it is the transformation of dragons, snakes, lizards, or energy-absorbing tree transformation dragons, the materials are rare, and the castle vault is just a place where some rare materials are collected in the gathering place of black lights, and the possibility of discovering them is extremely low.

Not to mention, most of the rarest and rarest materials in the entire gathering place are still stored in the teacher's private vault.

Su Huan planned to go to the teacher after selecting the secret vault of the castle, and inquire about the idea of the teacher's private vault.

After all, the treasures in the teacher's private vault can also be exchanged for contribution points.

The premise is that the teacher's consent is obtained.

And judging from the fact that the teacher provided him with dragon scales several times, Su Huan had a hunch that the teacher's secret vault might have a lot of treasure materials involving the dragon system.

In the end, Su Huan selected three materials in the castle's secret vault that were extremely rare in the outside world.

These three materials are the three main materials of the dragon transformation path that Su Huan has mastered and he values a lot.

The three materials cost a full 7,000 contribution points.

It's not that there are no other dragon materials in the secret vault that can be exchanged, but Su Huan plans to go to the teacher's secret vault first to take a look before talking.

In case the teacher has the materials he needs, and he does not have enough contribution points in exchange.

Su Huan soon saw the teacher in the restaurant on the third floor, who had not been out of lunch not long ago, and was sitting in front of the floor-to-ceiling window reading the important government decree documents of the gathering place that he needed to review in person.

"Su Huan." Seeing Su Huan coming, Zhou He beckoned with a kind smile on his face.

"Why are you here?"

"Teacher, I have some reluctant requests from you." Su Huan said respectfully, while turning his head slightly and glancing at his eyes, secretly looking at the teacher's left hand.

Seeing the strange energy that has disappeared without a trace, and the wound has healed the left hand.

Su Huan breathed a sigh of relief, immediately withdrew his gaze, and looked at the teacher seriously.

And Su Huan's relieved facial activity had already fallen into the eyes of Zhou He, who seemed to be reviewing government decree documents, but was actually paying close attention to him.

"Stinky boy, give it back to the teacher." Zhou He pretended to be serious, but actually laughed secretly in his heart.

"What's the matter?"

"Teacher, I have obtained a lot of materials in the Blood Forest Ruins, and I just got more than 10,000 contribution points to the gathering place, and it just so happens that I urgently need some materials, I want to see if your private vault is available, and if you can exchange it for me." Su Huan was not pretentious, and directly explained his intention concisely.

Zhou He put down the decree document submitted by the paper file, and readily agreed: "Come with me." ”

With that, Zhou He walked outside.

Su Huan followed the teacher with a stunned expression.

The teacher's promise is too refreshing.

Although he was a little surprised in his heart, Su Huan did not doubt him.

followed the teacher Zhou Hesu Huan all the way to the teacher's study.

Su Huan was a little puzzled, could it be that the teacher's secret vault was in this study?

Su Huan has been to the study many times, and he has met the teacher several times, and Su Huan is in this study.

Even the first time I met my teacher, I was here.

To be honest, Su Huan never saw the hidden mystery in this study.

It is a very large and spacious study.

Desks, bookshelves, tables, chairs, sofas, furnishings are clear at a glance and there are not many things.

In Su Huan's puzzled expression, Zhou He smiled and walked to a picture scroll behind the desk that was almost so big that it occupied half of the wall.

When Zhou He walked towards the painting, Su Huan suddenly showed a look of thought.

He remembered the last time he saw it, and it was a very abstract pattern, like a huge abstract painting.

Last time?

He pondered his memories, as if they were just some unconsciously messy lines.

But this time, the painting depicts a huge beast with a deep black body and a thick head and a hideous head.

It is similar to the pattern carved by the talisman pendant that Lu Yu handed over to him for the teacher.

The black beast stood between the vast sky and the earth, roaring at the sky.

A sense of desolation and simplicity arises spontaneously.

How come it is that every time I see it in the teacher, the picture depicted on this painting is completely different.

"This painting? You're too diligent, aren't you? Su Huan looked puzzled.

Before he could figure out why.

The teacher's actions surprised Su Huan.

I saw the teacher caressing his hand on the scroll.

The picture on the scroll suddenly became blurry.

The whole painting becomes writhing.

Then, the whole picture gradually became clearer, and a huge strange face appeared on the scroll.

Strange faces occupy most of the picture.

He has thick nostrils, thick black eyebrows, big brass bell-like eyes that look a little sleepy-eyed, and his mouth is muttering, and his whole face looks very funny.

When the face saw the teacher Zhou He, his eyes suddenly widened as if he had just woken up, and he grinned and said, "Master, is there anything wrong with waking me up from my deep sleep?" ”
