The vertical yellow light was the eye of a huge shark.

There was no time to dodge the tentacles of the octopus, and Zhao Sen was shot out.

The sea water in front of him was like thick ink rolling, gurgling, Zhao Sen choked a few mouthfuls of water, and immediately took out a bottle of underwater breathing medicine from the warehouse and poured it into his mouth.

His back hit the submarine reef hard, and Zhao Sen floated a -380 blood value above his head, waved his hand, and pulled back the blood value with divine blessing.

Looking back, Zhao Sen saw that not far from the submarine reef, there were many thick ice blocks.

Presumably, this place is not far from the Black Flame Volcano.

Zhao Sen swam towards the ice, and the blue ice stood quietly at the bottom of the sea, like delicate gems.

Not far away, there was a hole in a huge block of ice.

Intuition told Zhao Sen that he should go here.

Slowly swimming into this ice cave, a cold air rushed to my face.

There is an ice tunnel in the ice cave that can be crawled, and the amazing thing is that there is no seawater in the ice tunnel.

Slowly crawling forward, the ice tunnel has reached the end, and a thin layer of ice blocks the entrance to the cave.

Zhao Sen thought about it, turned on the sickle technique and began to chisel the ice.

After a while, the ice was chiseled through, and what appeared in front of Zhao Sen was a lake in the mountains.

Mountains on all sides surround this indisputable place, floating clouds and white sun, mountains and rivers **gentle,

The sun is abundant and abundant, and the dark green forests on the tall mountain peaks are surrounded by layers, making it appear even more empty.

However, under the ring-shaped rocks, there is a clear shallow lake, and the mirror-like lake reflects the reflection of the blue sky and white clouds, and everything is so peaceful.

Zhao Sen admired the surrounding scenery and slowly walked into the shallow lake.

In the center of the shallow lake, there is a silver prism, the prism is transparent, and there is a fist-sized purple bead floating on the top of the column, and the purple bead keeps spinning and jumping, never leaving the prism.

There seems to be something that imprisons it.

This purple bead is the treasure of the mermaid tribe, the heart of the dragon. And the first chapter of the Book of Sand is hidden in the heart of the demon dragon. Zhao Sen stepped forward, and the cool water overflowed his ankles, a little cold.

There was still a yard away from the Demon Dragon's Heart, and Zhao Sen stood still.

He trembled his fingers and reached for the whirling and jumping Dragonheart.

In the previous life, the three chapters of the Book of Sand fell into the hands of the leaders of the three super guilds, and some of the remaining fragments fell into the hands of some non-guild players, whose holders also had powerful powers.

But when they travel, they all keep a low profile, and they don't easily show off in front of people, and the power of some of the fragments of the Book of Sand, Zhao Sen has only seen it in the video. The three major chapters fall on the Freedom Wings Guild, the Demon Slayer Proud Blood Guild, the Ghost Legion Guild, and some fragments scattered throughout the Temple of the Rose Cross and Infinite Charm.

In short, these five guilds almost monopolized the Book of Sand.

At the same time, they also broke out fortress battles.

Zhao Sen had seen the fortress battle between the Ghost Legion and the Free Wings on the video, and the scene was magnificent, especially when the Freedom Feather Guild Guild Leader Brother Scar released the first fragment of the Demon Bone, hundreds of Ghost Legion's gold-swallowing wrestlers were pierced by it in seconds.

There is also the Demon Slayer Arrogant Decisive Battle Free Wings, when the mad soul finished collecting the second volume and released the group attack skill of the revenge butterfly on the first fragment of the second volume, the huge black butterfly like a dragon flew all over the sky, covering the sky and the sun, which made people fearful.

Zhao Sen felt his blood boiling when he thought about it.

A warm current came from his fingertips.

A cold voice sounded in Zhao Sen's mind.

"The era collapses, the tribe disappears, who is right and who is wrong? You have some resentment, but you can't do anything about it.

The magic of San Dio is infused into the world, who can rule it? You sigh, but you don't know. ”

Zhao Sen's fingers slowly clenched into fists and grabbed the heart of the demon dragon.

"Great demons, give you power!"

System: You learned the language of the Black Elves. The heart of the demon dragon slowly melted in the palm of his hand, and a white page lay quietly in the palm of Zhao Sen's hand.

Finally found it, Zhao Sen withdrew his hand in surprise and checked the attributes of the first fragment of the demon bone.

[Demon Bone] Fragment of a legendary item

Item description: The first fragment of the first volume of the Book of Sand

Item attributes: The holder of this item will gain 2 additional attribute points and 1 skill point for every five levels, attack +15, magic value +15, stamina +16, jump +15, magic rhino +15, and run +16

Skills: Soul Bone, Blessing Judgment.

Soul Bone: Summons the Bone of a Divine Spirit that pierces all targets within 20 yards of self.

Blessed Verdict, in a spell full exemption form after casting, HP +1500, with a high-level life shield, absorbs 80% damage, skill cooldown, and 10 natural days. Cooling state 1/10.

Restrictions on use: None.

Note: This item has an effect when placed in a backpack and will drop when it dies.

-------------------------------------------------------------------------------------------------------------------

Zhao Sen looked at the attributes of the demon bones and was in a trance.

The attributes of this thing are all exempted from just one spell, and it is extremely perverted, if you get a good piece of equipment, it will be ridiculously strong, and you will kill the gods when you see it

However, the cooldown time of the demon bone is also very long, it takes 10 natural days, that is, it takes 10 days to cool down, and he will not easily use this skill until the critical moment. In addition to the blessing ruling, other attributes are also very strong, especially getting an additional 2 attribute points and 1 skill point for every five levels, which is a super BUG.

A swordsman who can get 7 attribute points and 2 skill points by leveling up, Zhao Sen naturally understands what this means. Coupled with other attributes, it can definitely make a civilian become one of the best masters, and the demon bone is worthy of the name of a legendary item. Put the demon bone into the backpack and looked at the attributes, all the attributes immediately rose a lot. After the cooldown of the Blessing Ruling is completed, this magic that can only be cooled down in ten natural days has almost invincible lethality. But in the future, you should pay attention to the monster farming and PK, once you hang up, the demon bones will burst down, unless you can find all the 15 chapters of the first volume, and synthesize the first volume of the Book of Sand, so that it will not be lost.

What a hard job! Although Zhao Sen had obtained the demon bones, he did not let his guard down at all.

You can easily get the treasure of the mermaid tribe, of course, you can't go back easily.

Take out the Book of Return to the City and open it.

System: You can't go back to the city here

Can't go back to the city? Zhao Sen frowned, a trace of uneasiness passed through his heart, and he quickly moved forward, preparing to return the same way.

However, all the ice blocks just now disappeared, and a mountain peak was replaced by a mountain.

Obviously, Zhao Sen is like a bird that has been put in a cage.

Oops!

Zhao Sen quickly turned around, started the green art walking, and ran towards the mountain. This is a closed area, how could the system allow him to take the demon bones so easily! The merfolk clan's guards should be there, why hasn't there been any movement yet? Zhao Sen found a slope that was not too steep and climbed upwards with quick movements. There are many trees growing on the rock wall, which gives him a lot of points to borrow.

At this moment, the water of the lake not far away began to tremble.
