Among them, the blood drinking crazy devil and goddess are better. They just skip the level and retreat themselves. They only need one person to issue 100 billboard coins.

But ye Yun's words, that's a hundred thousand dollars!

The old man in black felt that his heart was dripping blood, and he was still very fierce.

Next, the old man in black took out a hundred billboard coins from the space ring and threw them in front of the blood drinking crazy devil.

"Examiner, this is a very useful coin in the inner door? The old devil has little knowledge. Can't you deceive me?"

The blood drinking maniac looked at the 100 so-called billboard coins in front of him, which were only the size of a fingernail, dark and common, and couldn't help asking questions.

In the eyes of blood drinking maniac, let alone Diyuan Dan, which can be used as a common currency among the four colleges.

That is, those gold and silver coins in the secular world look more dazzling and high-end than these black billboard coins.

But ye Yun doesn't think so.

Ye Yun's spiritual power can be felt. This coin actually contains mysterious energy, but it is completely isolated by the outer layer of black material.

"This is the billboard coin. In fact, if you look at my innocent face, you should know how honest I am. How can I deceive you?"

The old man in black pointed to his old face and vowed to speak.

"As for the purpose of billboard coins, you will naturally know when you enter the inner door."

The old man in black then opened his mouth and gave the goddess a hundred billboard coins.

When ye Yun was given 100000 billboard coins, the old man in black had a black face.

"Well, I'll test your mental strength in the fourth level."

Between the words of the old man in black robe, a spiritual stone has been taken out of the space ring.

This spirit stone was as like as two peas from the original Kowloon college to the Southern District.

"By the way, none of you should have more than ten grades of mental strength?"

The old man in black asked routinely.

After all, this kind of mental strength stone is relatively low-end, and it can't test more than ten products of mental strength.

"Cough, I may have reached more than ten products."

The first one to speak was the blood drinking demon.

Of course, he has never tested his mental power since he occupied the body.

I just feel that my mental strength is very high and may reach more than ten grades.

On one side, Caiwei, goddess and ye Yun nodded in agreement.

This surprised the old man in black again. There were seven people participating in the assessment this time. Unexpectedly, four of them may have reached more than ten grades of mental strength.

However, after thinking of the performance of several people in the previous examination, the old man in black robe was relieved again.

"It seems that I'm going to waste some money to open the mental strength test tower."

The black robed old man's face was full of flesh pain again, and then waved away the mental stone.

The mental power test tower is a relatively advanced item for testing mental power.

Every time it is opened, it takes a lot of energy.

In the sun moon sect, this energy obviously refers to the billboard coin.

The old man in Black said, taking out a small black tower from the space ring.

The black tower was only the size of a palm, but it grew to a height of tens of feet when it was suddenly thrown to the ground by the old man in black.

The small black tower is divided into twenty floors.

Each floor is the average height.

Next, with the input of hundreds of coins from the old man in black robe, a layer of black light suddenly appeared around the black tower.

This layer of black light is not strong, even a little soft.

"Well, you can play at will now. Remember, as long as you input the mental power in your body into the black tower, white light will appear on it. One of the spiritual power can make the first floor of the black tower burst out white light, and so on."

"Among them, you must at least reach the spiritual power of the seven grades, that is, promote the white light masterpiece on the first seven floors of the black tower at the same time, which is the fourth and last level of this assessment."

After a pause, the old man in black continued, "of course, once your mental strength exceeds ten products, there are rewards according to the regulations."

After finishing his words, the old man in black robe glanced at four people whose mental strength is likely to reach more than ten products, such as the blood drinking crazy devil. Especially, he stopped on Ye Yun's body for a while, and he could vaguely see the flesh pain on his face.

"Reward? Is it still the reward of billboard currency?"

A flash of light flashed in the eyes of the blood drinking crazy devil, and his heart was full of joy.

In response, the old man in black robe said, "yes, this time it is also a reward for billboard coins. If the mental strength reaches 11 products, it will be rewarded with 100 billboard coins. If the mental strength reaches 12 products, it will be rewarded with 1000 billboard coins, and so on."

The words of the old man in black made Ye Yun's eyes brighter.

The first one is senior brother.

The eldest martial brother thinks it's best to finish the assessment first. Otherwise, when ye Yun and others finish the assessment later, he will be hit and not in the mood to continue the assessment.

The elder martial brother came forward and transmitted a touch of spiritual power directly into the black tower.

The next moment, the black tower changed rapidly.

The white light works greatly and continues to spread upward.

It didn't stop until it spread to the ninth floor.

"Nine grades of mental strength, this achievement is OK!"

The old man in black began to praise, but it was comforting.

Because the results of the next few people can explode the eldest martial brother if there is no accident.

The next moment is Li Han.

At the moment, the aloof color on Li Han's face no longer exists. It seems that today's assessment has greatly changed his mentality.

Instead of releasing his mental power into the black tower, he sat down cross legged and closed his eyes for half a cup of tea.

This is adjusting the best mental state.

Finally, Li Han opened his eyes and absorbed a touch of spiritual power into the black tower.

Next, the white light on the black tower climbed directly to the tenth floor.

"Ten spiritual products, even better!"

The old man in black robe also began to praise. If it was the usual time, Li Han must have been very happy.

But now he didn't, but got up quietly and stood aside quietly.

Then Haidong came out.

At the moment, Haidong, like Li Han, is also extremely low-key.

His mental strength is the same as that of Li Han. He has also reached ten grades.

"Ha ha, the old devil will play next, otherwise when you three rebellious people play, there will be no possibility of being forced by the old devil!"

The blood drinking demon stepped forward quickly, and the words were not aimless.
