Chu Tianshu looked at the center of the hall, the energy array disk with a diameter of about 10 meters!

There are 342 mysterious symbols on it!

Every Xuanfu seems to represent an array, through which you can really control the whole situation!

With a little hesitation, he took out the demon crystal with thunder beast soul.

"Thunder attribute?" Bai Xuanyi and others were surprised!

"Could you fit in?" Chu Tianshu asked.

"I'll try. However, it's not easy to refine the thunder demon spirit. Moreover, my observation shows that the demon spirit in it seems to be more powerful than the ordinary level 3 demon beast!"

"Just try!"

Chu Tianshu handed the demon crystal to Bai Xuanyi!

Bai Xuanyi took it carefully, and then put the demon crystal in the center of the energy array!

The demon crystal floats up!

More than 300 runes gathered around the demon crystal and wrapped it up.

Then, it slowly infiltrates into it!

Through the demon crystal, people find the thunder beast inside and start to roar and struggle.

It seems not willing to be so bound, more unwilling to be used as a soul!

A trace of thunder's power appears on the demon crystal!

The array runes are forced out!

Bai Xuanyi's face turned white and frowned: "it's so powerful. Headmaster, I'm afraid the demon spirit is close to the fourth level monster, isn't it? Even if it's not quasi level 4, it's the peak of level 3! "

After hearing this, everyone was shocked!

Quasi level 4 monster?

That is beyond the existence of master Da Xuan!

Who can kill it?

Even the ancestors of the first-class clan are not sure!

Several people have a profound look at Chu Tianshu!

Chu Tianshu has some liver pain. He is a level 4 monster!

If you can refine in the future, you will certainly have more powerful fighting power!

But now in order to deal with the strong enemy, he is not willing to do nothing!

On the surface is very calm way: "nothing, slowly refining it!"

"It doesn't have to be successful. If you want to integrate into the quasi level 4 demon soul, you usually need the base of level 3 array!" Bai Xuanyi worried.

Chu Tianshu pondered for a moment and said, "but because of the power of thunder?"

Bai Xuanyi nodded: "well, it should be so. The power of thunder can resist the refining of Xuanfu. However, once the refining is successful, our mountain protection array will also contain some thunder attributes in the future, and its attack power will be higher!"

"I'll help you!"

Chu Tianshu went straight to the demon crystal!

Bai Xuanyi was startled, and said in a hurry: "the headmaster can't do it!"

However, he still said it was late!

Chu Tianshu's hand has fallen on the demon crystal wrapped by thunder!

A beam of electricity, all over his body!

Chu Tianshu's body trembled rapidly, and then he lay on the ground straight!

"Master!"

They were so surprised that they rushed up!

This is a quasi level Four demon soul. A Xuanshi like Chu Tianshu would be electrocuted at once!

Even if the electricity doesn't die, it will be severely damaged by the powerful demon soul!

However, in the face of the whole body current of Chu Tianshu, we do not know how to start!

I can only watch him quietly!

I can only pray that Chu Tianshu can survive.

If be killed, that Xuan Ling son still doesn't work hard with oneself?

……

Long lost pain, once again spread to every cell of Chu Tianshu!

He did not expect that this quasi level Four thunder beast soul was so powerful!

Had Zhao Liancheng not laid a solid foundation for himself before, he would have been dead!

However, thunder beast soul actually has the function of tempering body!

Now it seems that xuanlingzi didn't completely pit himself!

Under the operation of shenlei purgatory formula, the body strength is also slowly increasing!

In a minute!

Chu Tianshu sat up peacefully.Without saying a word, he pretended to take out a small bottle of ten thousand year old stone milk from his wide sleeve!

As soon as he lifted his neck, he drank it.

After the pain, it's the unbearable hunger!

It's too late to eat, even if the nutrition can keep up, it can't repair the damaged cells!

Only this ten thousand year stone milk can have that effect!

After a few mouthfuls, the hunger and pain will be gone!

Looking at Chu Tianshu's face that gradually returned to normal, everyone was relieved.

Bai Xuanyi worried: "headmaster, you are too reckless. This is a quasi level Four demon soul. Even his subordinates don't dare to fight hard. In case the headmaster has a problem, how can we explain it to master xuanlingzi?"

But Chu Tianshu stood up as if nothing had happened and said, "you don't have to worry. I can still resist. Come again!"

"Ah? No, absolutely not Bai Xuanyi hugs Chu Tianshu.

"I'm really OK!" Chu Tianshu said with a bitter smile.

Then Jianling King added in and said: "leader, although you have great talent to resist the thunder beast's attack, you may not be able to sustain the second and third time. This array of soul refining, just like the great Xuanshi's soul condensing, needs a little bit of grinding. We are not in a hurry!"

"Ah... I really can, you really don't have to worry, you let me try again!" Chu Tianshu pleaded.

But a few people did not let go!

Chu Tianshu can only sigh: "OK, you let me go, I won't do it!"

"Seriously?"

Chu Tianshu nodded.

A few people just let him go!

But the next moment, Chu Tianshu's hand, with the power of lightning, once again put on the demon crystal full of current!

"Ah Several people exclaimed at the same time!

See Chu Tianshu's body, shaking violently again!

A moment later, he lay on the ground again!

"Why are you so disobedient?" Bai Xuanyi also trembled with anger!

But in everyone's surprise, Chu Tianshu actually opened his eyes again!

He took another sip of Wannian stone milk and said with a smile, "I didn't cheat you, did I? The power of thunder can harden my body

"Is the leader's Xuanqi seed thunder?" The king of the sword mausoleum is a stranger.

"You may think so. Let's come again!"

Chu Tianshu put his hand on the demon crystal again in everyone's worry!

The current is still very violent!

Chu Tianshu lay straight down again.

So repeatedly more than ten times!

They found that Chu Tianshu's time on the ground was getting shorter and shorter!

Although every time you need to drink a few mouthfuls of stone milk, the smell is stronger and stronger.

"Is the headmaster really practicing with the help of thunder? But how can he sustain such a violent energy as a Xuanshi? " The crowd said in secret.

He also looked at Chu Tianshu with new eyes.

This level of thunder power, even Da Xuan master, is not necessarily able to resist!

But Chu Tianshu used it to refine his body. How could it not shock people?

With Chu Tianshu constantly absorbing the power of thunder from the demon crystal, the thunder beast in it doesn't seem to be so irritable at the beginning.

Bai Xuanyi seizes this opportunity to mobilize Xuanfu again to rush into the demon crystal!

Bound to the spirit of thunder beast!

Thunder is still struggling!

However, its thunder power was absorbed by Chu Tianshu and could no longer be used to resist the control of Xuanfu.

Half a day!

Soul refining is success!

After thunder beast is locked by Xuanfu, it can be regarded as successfully integrated into the array!

Pulled out by the success of the demon crystal!

Turned into a unicorn like energy giant
