According to the information xuanlingzi sent to Chu Tianshu.

Chu Tianshu also knows that inside the sarcophagus, it should be the master of the dragon bone sword, quasi level Four demon soul, and shenlei's purgatory formula!

It was these three things that made xuanlingzi.

So that when xuanlingzi was dying, he was grateful to him.

"I don't know who you are!"

Chu Tianshu looked around again.

I was disappointed.

Because there's nothing but this coffin.

The way he expected to evolve thunder also does not exist.

It doesn't matter that shennian scans the cave again and again.

Finally, his eyes fell on the coffin again.

In fact, Chu Tianshu also has a sense of the situation inside.

There is nothing but a corpse.

The dead should have been people thousands of years ago. The flesh and blood have rotted, leaving only skeletons.

Chu Tianshu guessed that this person may not be a native of the east continent, but may have come from other continents.

It's not even human, it's also possible to be the demons!

After all, how can ordinary human beings possess such divine level skills as shenlei purgatory formula?

And the dragon sword?

As for the level 4 spirit thunder beast, it is not what the Donglu people can have.

It's not so easy to kill level 4 demon Zun.

Not to mention the thunder monster with the most terrible attack power and speed.

"Master, I'm sorry to disturb you again!"

Chu Tianshu used his mental power to scan the bones in the coffin again and again.

The skeleton is like jade. It has not rotted or deteriorated for thousands of years. It can be seen that it should have been a profound cultivation before his death.

At least, it should be xuanzun realm.

In the skeleton, Chu Tianshu also felt the power of thunder.

It can be seen that what this person should practice in his life is also the secret of God thunder purgatory, and he has already cultivated the power of thunder into his bones.

It's just that there's nothing else.

"It's estimated that all the things that can be taken away have been taken away by xuanlingzi at that time."

"Well, I didn't ask for too much, so I thought it was for xuanlingzi to return his wish!"

Chu Tianshu took a deep breath, raised his hand, and took out the thunder beast demon soul, the dragon sword, and the soul jade sealed with shenlei's purgatory formula.

He said: "master, these things belong to you originally, and xuanlingzi took them from here. I don't know if he has your consent. But as half of his descendants, I'm here today to express my gratitude to you and kowtow to you instead of xuanlingzi!"

Chu Tianshu knelt down and put three things in front of the coffin.

He made three respectful kowtows.

Then, he held up the three items and put the shenlei purgatory formula on the coffin.

He said: "master, if you want to leave shenlei's purgatory code here, it will be for someone who has a destiny. I need to keep the other two things and continue to use them. I hope you will forgive me."

Then, around the coffin, he blessed a dream space and dreamland.

In this way, from the outside world, we can't find another coffin here.

After thinking about it, he took out a piece of demon bone and ghost with lightning attribute.

They were also placed next to the coffin.

The spirit bone and spirit are all from the third level monster comparable to the master.

Combined with shenlei purgatory formula, it can be regarded as a complete inheritance.

If one day someone like xuanlingzi comes here by mistake, it will be a big chance.

After all this, Chu Tianshu came out of the cave.

Standing at the entrance of the cave, listening to the roaring thunder and looking at the lightning like the silver dragon, Chu Tianshu suddenly felt that the keel sword in his hand was trembling slightly.

It seems to be a life with some wisdom. I feel that the environment here is a little familiar.

It's like ordinary people are excited when they go back to their hometown.

In this regard, Chu Tianshu is also very emotional.

This dragon bone sword is an artifact.This life, it is estimated that they will not give up easily.

The higher your accomplishments, the more you can understand the importance of artifact.

He even has some understanding of why human beings have no divine blood and gods to stand among all races.

In addition to Phoenix Fire, it is an artifact.

Chu Tianshu guessed that among human beings, there are absolutely not a few artifacts such as dragon bone sword.

With the help of artifact, the combat effectiveness of human beings will be more powerful.

It's not impossible to challenge at a higher level.

What's more, you can use artifact to set up a stronger array. Maybe you can kill gods.

On weekdays, he seldom used the keel sword.

Compared with the gravity hammer, the keel sword is the real artifact to protect life.

He doesn't want too many people to know about it!

After all, the gravity hammer can't be taken away by others. Even Chu Tianshu can't integrate the gravity hammer into his flesh and blood, and he can't figure it out.

However, the dragon sword is always hidden in the body, protecting the soul of war and Chu Tianshu.

He stroked the body of the sword and said to himself, "this dragon bone sword may be the skeleton of the dead real dragon in ancient times, which was picked up by some living creature and refined into an artifact. Of course, it may also be a descendant of the real dragon, the corpse of a dead Dragon son. After several times of circulation, it came into the hands of the owner of the sarcophagus!"

With it, Chu Tianshu doesn't have to worry about his warspirit being blown up.

In order to better control the already arranged heaven and earth destruction array in the body.

Raise your hand, Chu Tianshu will raise the dragon sword.

Boom!

There was thunder in the sky, and a bunch of terrible thunder suddenly fell from the sky and landed on the keel sword.

In this regard, Chu Tianshu was slightly surprised.

I was even startled.

Even though he has xuanzun level fighting power, he dare not underestimate the power of heaven and earth.

It's not for fun that the thunder is so powerful.

Even Emperor Xuan could be killed.

But then he was shocked.

From the dragon's bone sword, there was a thunder force pouring into his body.

Make Chu Tianshu's body tremble violently.

But the strength of this thunder force is also within his acceptance range.

With a little operation of shenlei purgatory formula, the power of thunder will be absorbed by flesh and blood cells.

In a moment, he was back to normal.

Looking up again, another thunderbolt came down from the sky, as if it had been led by the dragon's sword.

The lightning, which seems to be powerful, is very weak after being filtered by the dragon sword and introduced into chutianshu's body.

This, Chu Tianshu suddenly realized, also excited.

Isn't that the way he's looking for to evolve thunder?

In the world, which natural resources and treasures, or the thunder in the monster's body, is more powerful than the thunder in the world?

Before, he couldn't get energy directly from heaven and earth.

Because a man is not well controlled, he will be killed alive.

But with the dragon bone sword, he doesn't have to worry.

"Why am I so stupid? Why didn't you think of this before? " Chu Tianshu said in secret.

With the power of thunder coming into the body, his divine thunder purgatory formula is rapidly improving.

The three kinds of energy in the body tend to balance again.

Chu Tianshu even had a feeling that if he stayed here to practice, and combined with dragon blood stone and Phoenix stone, he would reach the realm of xuanzun within a month.

Unfortunately, tomorrow, he will have to follow Ye Xuan to the Middle Earth.

I can't stay here long.

If you put the dragon sword into your body, the thunder and lightning in the sky will no longer land.

"It's getting late. It's time to go back!"

Chu Tianshu waves out a few first-class demon bones and arranges another array at the entrance of the cave.

That's what's going on
