In fact, Zhang Bin secretly suspected that this skull was also an internal practitioner during his lifetime.

Many bone cells have been developed into the inner universe, which is why it is so heavy.

His mental energy surged over and he examined it carefully.

Unfortunately, this skull emits a gleaming white light, and is extremely fine.

His mental power couldn't even enter.

A thunder soldier appeared in Zhang Bin's hand, and he slashed the skull with his sword.

But not even a single trace appeared.

Extremely hard.

"I will study it more carefully when I have time, and maybe I will find out some secrets."

Zhang Bin murmured in his heart, and he took the skull into the treasure room in the central Dantian.

Then he came to the pile of Jade Eye Slips.

I read dozens of Jade Eye Slips in one breath, all of which were emperor-level exercises. Unfortunately, most of them were incomplete.

You cannot cultivate to the level of Immortal Emperor.

But it still has huge benefits for Zhang Bin.

He asked Nan Shaojie to put away all these Jade Eye Slips so that he could have time to read them carefully, maybe he could find a special technique to deal with the Tears of Death Sword.

Anyway, all these Jade Eyes Jane Tutu have been read and stored in the mobile phone. Zhang Bin can take a closer look at any time.

Finally, Zhang Bin came to the pile of books.

His face was full of excitement and excitement.

He immediately grabbed the dark book.

A few words on the cover are shocking: Dark Souls.

Zhang Bin read it carefully.

This is a dark attribute skill. Darkness represents death. When darkness comes, everything will die. However, if you cultivate the dark soul, you can still survive even in the dead darkness, and your soul can continue to exist forever.

Zhang Bin was so excited that he almost fainted.

Now he has practiced the Heavenly Demon Art to the limit.

The soul wants to become stronger again, but there is no way to do it.

Yes, the highest achievement of the Heavenly Demon Art is to condense the immortal soul armor and soul furnace.

However, Zhang Bin has successfully condensed it. In the future, as the realm improves, the power of the immortal soul armor and soul furnace will also increase.

However, there is no way for the soul to become significantly stronger.

The book Dark Souls points out a new path.

It can take the soul one step further, and it can become immortal forever without wearing the immortal soul armor.

"This is a peerless treasure."

Zhang Bin shouted excitedly in his heart.

Immediately, he followed Tutu's instructions and pulled out a green book, which also exuded the aura of immortality.

The name of this book is - Homesickness Song.

It turned out to be a kind of musical score, and Zhang Bin felt dizzy just by looking at it.

Because it's too complicated and I can't understand it.

"Master, this song is very scary. It has magical power. It is infinitely better than the Sound Wave Mysterious Skill you obtained. If you can practice it successfully, then even if you encounter a black ship, you may be able to play the homesickness song to fight against it." Tutu

Zhang Bin said in his mind, "Besides, don't you think the name Homesickness Song is weird? It's similar to the song of Black Boat?"

"I'll study it slowly when I have time."

Zhang Bin was also secretly happy and looking forward to it, and he also put the book away solemnly.

He spent three days searching and reading here.

The same goes for Nan Shaojie, who found many useful treasures.

"Shaojie, I'm going to practice in the Forbidden Sea... You can practice hard in the territory. Remember, you must be careful to guard against Nan Chengping's plot." After Zhang Bin finished speaking, he left in a flash, and he also took Yang Xiong with him.

Yun Feiyang, Octopus King, Golden Winged Peng King, Leopard King, Wu Jun, Sheep King and others.

Eel Aijiao and Wu Dayong, who led the army, were left behind.

Of course, he secretly told Yu Aijiao to protect Nan Shaojie.

Now Eel Aijiao has cultivated to the level of Demon King, and her body is in the early stage of Demon King.

His strength is no less than that of Nan Taiping.

She protects Nan Shaojie, as well as numerous ancient blood mosquitoes.

What's more, there is the Antarctic Immortal Emperor secretly protecting him.

There will definitely be no problems with Nan Shaojie, and the territory will definitely be extremely safe.

Even if he might encounter a black ship in the Forbidden Sea, Zhang Bin would not care about it.

Because he must become stronger faster.

However, he is still very careful and never walks on the forbidden sea.

Instead, it sank into the water from the seaside and quickly moved from the bottom of the sea to the deep sea.

Even if the black ship came, it would be impossible to find him at the bottom of the sea.

Then there won't be any danger.

"You went to the Forbidden Sea? You are very courageous." Of course the Antarctic Immortal Emperor sensed it, with a sneer on his face, "Zhang Bin, I was actually deceived by your deception ability, and it was detected that you only had 60 Dantian areas.

.Actually, you have 81 Dantian areas, right? So, you can easily kill the invincible Immortal King who has mastered the Tears of Death Sword?

Moreover, I had only reached the early stage of Immortal King cultivation at that time. Also, I secretly calculated about you, but I couldn't figure out any information about you. You know, I can even guess a few clues about you from an emperor-level master. However, you are my son-in-law.

It's really hard to kill you personally, so I can only let Nan Chengping do it. This year is just used to stabilize you..."

Finally, Zhang Bin entered a very deep place in the forbidden sea.

He began to practice hard.

The internal cultivation energy circulates rapidly in the meridians and penetrates into every part of the body.

Activate more cells.

But Zhang Bin quickly stopped and thought to himself that I have practiced the magical Heaven-Mending Technique, and my internal cultivation talents have been greatly improved. The previous exercises no longer match, and I have to create more suitable ones.

He started trying it right away.

First, he studied the internal cultivation talismans in detail, and then slowly created an internal cultivation method that was most suitable for his own practice.

He started practicing tentatively.

Gradually, Zhang Bin's face showed joy.

Because the practice is effective, this technique is indeed much better than the previous ones.

The speed of activating cells is about three times faster than before.

"Hahaha... I can become stronger faster. Antarctic Immortal Emperor, I will hit you hard in the face. I will beat you to pieces." Zhang Bin sneered in his heart.

He continued to practice hard, enduring the extremely terrifying pressure of sea water. How could it be stimulated? The internal cultivation Qi circulated like light and electricity. At the same time, he was also working hard to understand the mysteries of Dark Soul and Homesickness. Because it was too complicated

With Xuan Ao, progress is very slow. But Zhang Bin is not in a hurry, because he can become stronger through internal cultivation.

Half a month later, Zhang Bin finally reached the limit of the middle stage of Immortal Realm.

The internal spaces of all his activated internal repair cells stopped expanding, and the true energy in his Dantian could no longer increase.

He reached a point where he could no longer improve no matter how hard he practiced.

That is to say, it has reached a bottleneck.

To become strong, he must break through.

If he hadn't met Mo Wan, he wouldn't have known how to break through.

However, Mo Wan told him the secret of the breakthrough. That was to cut through the wall and steal the light.

At this moment, Zhang Bin was sitting cross-legged in the underground cave of the pirate island.

He was thinking carefully, "What does it mean to cut through the wall to steal the light?"

And Yang Xiong, Yun Feiyang and others are protecting Zhang Bin.

They are also very powerful now.
