The black dragon's words made Yang Chan's heart jump slightly.

The rewards of the trial were not as bad as he expected, if the box was not big, the things that could be obtained would be limited, but the box had its own space, but it was different.

Fortunately, he has the treasure of the Xuanyin Hanging Bead, otherwise he may feel a pity because the box can't be taken away.

Yang Chan looked at these boxes, and a hot color flashed in his eyes.

For him, it's like opening a blind box, always giving people a sense of unknown anticipation.

"Can you see through these boxes?"

Yang Chan looked at the black dragon on the side and suddenly asked.

Although most of the blind boxes are rewards, they can also be frightening and even dangerous.

Yang Chan couldn't see through it with the naked eye, but the black dragon was not.

"No, it's blessed with the power of isolating the investigation, and the soul body can't see through it at all!"

The black dragon hovered next to Yang Chan and shook his head slightly.

In his sight, this is still a sealed box, which cannot be seen through at all, which is also the special feature of these boxes.

This is made with great supernatural powers, and it is also to prevent detection.

"Is it dangerous?"

Yang Chan continued to ask.

He hadn't forgotten that some people always had all kinds of mechanisms in these boxes, and when they opened them, all kinds of hidden weapons came out to deal with these people who opened the boxes.

His cultivation has reached the realm of the Great Grandmaster of Cleansing the Marrow, and there are not many hidden weapons that can hurt him, but there are still some powerful poisons, which can seal his throat with blood, and directly turn his body into a body.

He can ignore ordinary poisons, but he can't solve this kind of poisonous things.

In particular, these boxes themselves are extraordinary, and the people who made them are not ordinary people, and it is still unknown who has such means.

"I don't know, because there is a special power blessed on it, I can't see through it at all, and I can't feel the danger!"

"I don't know anything except to turn it on!"

When the black dragon heard Yang Chan's words, he was stunned for a moment, but he also reacted, this is the steady Yang Chan.

I didn't lose my mind because I saw many treasures, and I didn't lose my vigilance about these rewards because of the trial rewards.

Ordinary people may not wonder if there is danger on these boxes and open them directly, but Yang Chan will not at all.

"Otherwise, the master should not open it with his own hands, I will help the master open it!"

After the black dragon reacted, he took the initiative to ask for help.

Because he understood that Yang Chan's purpose in asking this was not to open the boxes himself, but to let him open these boxes.

After thinking about it, the black dragon took the initiative to speak, and he was extremely empathetic.

"Well, I'll open it for you!"

"With this flying claw, you also have time to react if there is danger!"

Yang Chan naturally happily agreed.

Although it is very fun to open the blind box, it is better to hand over the unknown blind box to the black dragon.

When the black dragon heard this, he took the initiative to take it, and used his soul power to control the flying claws, and after touching the first box, he saw a black light flickering on the box, and then the box spread out, revealing the treasures inside.

"Keys?"

There was no hidden weapon shot, and the box was opened directly, but the items inside were beyond Yang Chan's expectations.

Because there was a key floating inside, it made him look a little confused.

The reward of the trial gave him a key, which was to open something, and it was difficult to open the other two boxes.

"It should be the key!"

The black dragon looked at this key with a very strange appearance, but it should still be a key, but the appearance was a little strange.

Suddenly, the black dragon's heart moved.

"Master, why don't you take out the special box you found before entering the Elite Trial Array?"

The black dragon suddenly thought of the special box that Yang Chan dug up in that space before entering the elite trial array, and at that time, it couldn't be opened at all because there was no key, and at this time, from this trial reward, this special key was opened, maybe it was the key to the box.

After all, the box that can be obtained before the Elite Trial Array should also be obtained in the Elite Trial Array, and this Elite Trials Array is the most likely.

It's just that this is a bit of a coincidence.

"Hmm!"

Yang Chan's thoughts moved slightly, and he saw the strange-looking box that had been placed in the Xuanyin Hanging Bead appeared in front of him.

He had been curious about what was in this box, after all, whether it was hidden before the Elite Trial Array or in the underground.

Without special means, it will not be discovered at all.

Previously, before the Elite Trial Array, the Holy Sons and Holy Maidens of many Holy Lands, the princes and daughters of the Imperial Dynasty, all of them were not simple characters, and in the end, they still did not discover this hidden box, which shows that this hidden ability is extremely strong.

He didn't believe that before these people came to the Elite Trial Array, these people would not use the means of investigation to investigate.

It's just that none of these people found the box.

"You go and try to open this box!"

Yang Chan directly asked the black dragon to open the box.

There is no danger hidden in the box of trial rewards, but this box placed in front of the elite trial array is not necessarily.

Someone may have done it on purpose, or someone may have suppressed something inside, or there may be hidden treasures, and everything may have it.

Just like this, the former black dragon was also suppressed in the tower of the cloudy sky, if it weren't for the Xuanyin hanging beads, Yang Chan's side might have been hit.

"Good!"

The black dragon directly picked up the key from the box in the trial reward and put it into the box that Yang Chan took out from the Xuanyin Hanging Bead.

Yang Chan was also watching from the sidelines.

I saw that the strange key was placed in front of the strange box, and the appearance of the key began to deform, and the box was too, and the keyhole changed accordingly.

Both of them are not the original appearance, if Yang Chan follows the keyhole of the box to configure the key, it should not be opened at all, and even trigger the power in the box, and it is even possible that the box will be destroyed, and at the same time affect his possibility.

"It seems that the contents of this box are not simple, otherwise they would not be placed like this."

"Master, you take these two trial boxes aside, you and I should take a step back!"

Before the box was opened, the black dragon opened his mouth to warn, because the box placed in this way is not easy to look at, and it is likely to hide danger.

And if there is danger in it, it will be the black dragon who will face it head-on, because Yang Chan will use the Xuanyin hanging bead as a counterpart.

The black dragon knows this very well, so he will remind him, otherwise he will be the unlucky one at that time.

After the two of them retreated, they saw a pitch-black aura emerge from the box, and these breaths carried an extremely uncomfortable aura, and even the body instinctively feared these aura.

"This is the primordial demon element of the Ancient Great Demon!"

On the black dragon's side, it was also extremely unexpected to see these auras emerge, and directly revealed the source of these pitch-black aura.
