The Book of Abyss in Song Jian's hand is actually a complete number of skills, with a total of nine layers, and there are only two skills in the first layer, one is "Abyss Demon Armor" and the other is "Abyss Charm".

The Abyss Demon Armor uses the fourth-order Abyss Flame to condense a full-body armor on the surface of the body, but this armor only increases resistance and does not provide defense.

Another "Abyss Charm", this skill not only takes a long time to release, but can only be used when the target is unable to move, or even when the target is seriously injured and loses the ability to resist, another disadvantage is that after a long time, the chance of being betrayed by the enchanted creature is extremely high, and Song Jian tried it a few times, and he never used it again.

These two skills were not very helpful to Song Jian, so Song Jian did not continue to activate the skills on the Abyss Book skill tree;

However, at this time, in the face of the betrayal of the Abyss Demon Lord in front of him, Song Jian suddenly felt that a skill in the second layer of the Book of Abyss was very suitable for dealing with it;

"Abyss Skill - Shackle Mark: Use the target's flesh and true name to imprint its soul shackle mark, the mark exists for three months, and during the existence of the shackle mark, you can torture the target's soul at any time, and even directly destroy the opponent's soul! This skill requires 230,000 combat experience to activate! This skill can only be used once on the same target! ”

"It's a tailor-made skill for you!" The corners of Song Jian's mouth curled slightly, and he didn't hesitate to light up this skill, and the experience value that had been raised to level 31 to 29% suddenly became 2% of level 31;

"You want this, don't you?" Song Jian shook the Book of Abyss in his hand and smiled at the Abyss Demon Lord;

"Yes, give him to me!" The Abyss Demon Lord's eyes showed a greedy look, he was originally a middle-aged human, a layer of purple-black scales began to appear on the surface of his body, and the demon horns on his head also loomed;

"Then I need you to exchange things with me!" Song Jian held the Book of the Abyss and walked towards the Abyss Demon Lord step by step;

"Something for a change? What is it! The Abyss Demon Lord's face sank, and he whispered, "I said before, now I don't have any items except for this broken body!" ”

"What I want is your broken body, no, to be exact, your broken demon heart!" Song Jian's eyes narrowed, his right hand pointed towards the Abyss Demon Lord, and five sword qi stones floated around his body out of thin air, flying towards the Abyss Demon Lord;

Boom, boom, boom, boom, boom~

Five roars rang out around the Abyss Demon Lord, and five rounds of scorching golden light rose up at the same time, like the five suns;

"Great Sun Golden Light Sword Array, Slash!" Song Jian let out a soft snort, and the five rounds of scorching sun above the head of the Abyss Demon Lord bloomed with endless golden sword qi, each sword qi was comparable to Song Jian's skill "Bright Slash"!

"Human, what are you going to do?" The human body of the Abyss Demon Lord swelled violently, turning into a demon giant with a height of more than three meters, which was the original appearance of the Abyss Demon Lord at this time, almost exactly the same as the phantom that appeared in the air before;

"This is a punishment for not keeping the contract!" Song Jian shouted in a low voice, his figure was like lightning, and he rushed towards the Abyss Demon Lord;

"Don't think that's going to scare you, human!" The Abyss Demon Lord said viciously: "I am already free, although I am very weak now, but do you think that just by you, with this tickling sword formation, you can kill me, it's ridiculous!" ”

A long black knife nearly two meters long appeared in the hand of the Abyss Demon Lord, the blade of the long knife was extremely sharp, and on the back were several huge serrations, and the surface of the long knife was burning with raging black flames;

"Abyss Strike!" The Abyss Demon Lord roared, and the long knife in his hand slammed into the air, and a brilliant black sword qi slashed towards a round of scorching sun!

Rumble!

There was a loud bang, and the whole hall shook slightly, and the dust "fell" down;

A round of scorching sun condensed by golden sword qi was shattered, and the sword array suddenly became incomplete, losing one-fifth of its power;

But the other four rounds of scorching sun were still releasing endless golden sword qi, like the light of the sun, constantly slashing at the body of the Abyss Demon Lord;

The Abyss Demon Lord laughed, although hundreds of points of damage continued to float above his head, but for him, whose qi and blood value had exceeded 50,000, this damage was nothing, but instead gave him a feeling of returning to the battlefield;

"This bit of damage, not even reaching the first level of combat power, to me, it's like tickling!" The Abyss Demon Lord roared, "Just let me help you abolish this fragile sword formation. ”

The Great Sun Golden Light Sword Array was enough to kill hundreds of monsters above level 30, but for the Abyss Demon Lord, this damage was not fatal!

At this time, it had already lost more than 5,000 qi and blood points, but it still had a look of indifference on its face, brandishing its black long knife, and continued to slash towards the remaining four rounds of scorching sun;

"Broken, broken, broken, broken! Destroy them all! ”

Boom, boom, boom, boom!

The violent explosion made the sealing hall, which had already experienced a huge explosion, even more fragile, and large rocks fell from the top of the head, and huge cracks also appeared in the surrounding walls, as if the entire hall was about to collapse in the next moment.

Five consecutive blows with all his strength broke the "Great Sun Golden Light Sword Array", and the Abyss Demon Lord also became a little tired, this sword array made it lose more than eight thousand points of qi and blood, for it that was already weakened to the extreme at this time, breaking this large array was not as easy as it appeared;

"If there are any other means, just use them all, human, and when everything is over, I will use your flesh and blood to replenish the consumption in the battle!" The Abyss Demon Lord's eyes became fierce, the content of the contract, there is nothing that cannot kill the other party, as long as it kills Song Jian, and then destroys the Qingyun Sword Gate entirely, and completes the content of the contract, it will not be affected by the power of the contract;

After it finished breaking the sword array, it suddenly found that it had lost Song Jian's figure;

"Human, where are you hiding?" The Abyss Demon Lord's heart sank, could it be that this human took the opportunity to run away?

At this moment, a brilliant pillar of golden light suddenly stabbed out from its back, directly through its body, and through its chest;

A critical hit of more than 3,000 points floated up from the top of his head;

At this time, Song Jian was standing behind it, his left index finger pointing diagonally upward, and the golden sword qi was blooming from its fingertips;

"Human!" The Abyss Demon Lord was furious, if its body was damaged, it could be repaired indefinitely, but if the heart was damaged, it would cause irreversible damage, and Song Jian's blow was aimed at its broken heart.

A large hole appeared in his back, and Song Jian's heart moved, and his steel wings spread violently, driving Song Jian to pounce towards the body of the Abyss Demon Lord;
