With the steel wings swing, Song Jian flew up and rushed towards the back of the demon lord of the abyss;

He pulled out the broken heart of the Demon Lord of the Abyss from the big hole in the back of his heart. Song Jian whispered in the other person's ear: "I said that what I want is your flesh and blood!"

"Abyss Blade Savrans Kutuya Sara..." Song Jian chanted the real name of the Demon Lord of the Abyss, and the demon heart, which was less than one-third left in his hand, was beating violently as if he was frightened;

The Book of the Abyss appeared before Song Jian, and the pages of the book were automatically without wind, and a mysterious black aura spread out from the book;

The Demon Lord of the Abyss heard Song Jian’s real name, and at the same time, the other party was still holding his heart in his hand, and suddenly felt something was wrong;

"Human, what are you doing? Do you think that heart is indispensable to me?" The Demon Lord of the Abyss was a little panicked. If he lost his heart, it would take at least a thousand years to return to his peak state;

“Give it back to me!”

Because the real name of the Demon Lord of the Abyss was too long, Song Jian quickly recited it, but he could not stop the other party from rushing over to grab the heart.

However, the moment the Abyss Demon Lord's big hand grabbed Song Jian, an invisible transparent light curtain firmly protected Song Jian;

The Demon Lord of the Abyss could only scratch the light curtain with his hands in vain, causing ripples, but he could not break through this layer of defense anyway;

"Use its real name as a guide, its flesh and blood as a basis, the shackle mark, mark!" Song Jian grabbed the right hand of his heart, pointed at the Demon Lord of the Abyss, and suddenly a black flame appeared out of thin air and flew towards the Demon Lord of the Abyss;

Hissing ~

At its forehead, a blooming black lotus bloomed with dazzling light, and the demon lord of the abyss let out a shrill roar, holding his head and rolling on the ground;

Song Jian glanced at the demonic heart in his hand, and it consumed some of the release of the shackle mark. Now there was less than a quarter of the whole heart, and it was impossible to see at all. This bloody and flesh ball was a demon's heart;

He threw the remaining heart to the Abyss Demon Lord who was rolling on the ground. Song Jian wiped the purple-black blood on his right hand with some disgust, and looked at the Abyss Demon Lord with a cold face;

"What did you do to me, what did you do to me, damn human, I want to kill you, kill you!" The Demon Lord of the Abyss roared loudly, rushed towards Song Jian with his teeth and claws;

"Sign, it hurts!" Song Jian looked at the abyss demon like a giant and rushed towards him, without moving, standing there, shouting lightly;

Suddenly, the demon lord of the abyss felt a split headache, as if someone was wielding a sharp axe and constantly chopping his head, and it seemed like a red-hot iron needle pierced into his head, stirring constantly;

This pain is not physical, but comes from the depths of the soul;

The pain lasted for fifteen minutes. The Demon Lord of the Abyss seemed to have lost all his strength, and collapsed on the ground like a pool of mud. His body kept twitching, and a trace of blood appeared in his seven orifices;

"No, give up your life, spare me, let me go, I will definitely abide by the contract. As long as I recover a little, I will immediately help you seize the treasure you want from the Qingyun Sword Sect!"

The Demon Lord of the Abyss finally couldn't bear the pain like the soul tearing, and begged for mercy to Song Jian;

Song Jian smiled slightly, and thoughts moved, and the Demon Lord of the Abyss suddenly felt the pain disappear;

"You, what did you do to me?" asked the demon lord weakly;

"It's nothing, it's just a few tricks, which can ensure that you follow the contract!" Song Jian gently kicked the Demon Lord of the Abyss on the shoulder with his toes and said, "Don't pretend to be dead, get up quickly, and recover your strength as soon as possible. As long as you help me destroy the Qingyun Sword Sect, I will cancel this shackle mark!"

After a long time, the Demon Lord of the Abyss returned to his human form and struggled to get up from the ground. He looked at Song Jian with a complicated face and said, "Humanity, I hope you can keep your promise!"

"Do you think I am the abyss demon?" Song Jian said disdainfully, turning around and walking towards the passage;

...

A month later, Qingyun Town, which is closest to the ruins, has been slaughtered, and the entire town cannot even find a body;

"The humans in this town are so weak that I can't replenish enough energy at all, and they are not even as good as the town we have been to before!" complained the Demon Lord of the Abyss in a black cloak;

As soon as he came out of the ruins, Song Jian took the Abyss Demon Lord and directly destroyed several towns in the secret realm of Chiyang Sect. All the flesh and blood of humans were used to restore the power of the Abyss Demon Lord;

Until now, the power of the Abyss Demon Lord finally recovered to the early stage of the second-level combat power, and the level soared to level 51;

However, even though the strength of the Demon Lord of the Abyss was much greater than that of Song Jian, the effect of the shackle mark in the soul did not weaken at all, which also made the Demon Lord of the Abyss who was ready to move instantly calm down;

"It is said that there are many treasures in this secret realm!" Song Jian looked into the distance, touching his chin with a thoughtful look.

"I can go and grab all the treasures for you, as long as you can untie my shackles!" the Demon Lord of the Abyss whispered.

"Forget it, Qingyun Sword Sect is more important!" Song Jian hesitated for a long time, and finally gave up this tempting idea;

You should know that with the strength of the Demon Lord of the Abyss, in this secret realm, it is simply a sweep, and no one is its opponent;

Unless there are even stronger monsters hidden in the secret realm, if there are really such monsters, Qingyun Sword Sect and Chiyang Sect will not be unknown until now;

The Shackle Mark has only been invalid for three months. It took a month for the Abyss Demon Lord to recover to the early stage of the second-level combat power. If he really wanted to explore the treasures in the secret realm, time might pass quickly. By then, Song Jian would have no means to limit it, and the assessment task would be postponed unlimitedly.

"What a pity. This skill limit can only be used once for the same person. Otherwise, it would be possible to keep it by my side!" Song Jian murmured in a low voice;

"You can teleport out from this teleportation array first, be careful. There are a few old monsters opposite the mountain of Qingyun Sword Sect. I'm afraid you are not your opponent now. Be careful to lurk and attack them after you have recovered your strength!" Song Jian pointed to the teleportation stone platform and ordered.

"Don't worry, the Abyss Demon is the race that is best at disguising, no one!" The Abyss Demon Lord showed a smile on his face, and his body swayed like a wave of water. In a short while, he turned into the appearance of Evergreen River;

Nodding at Song Jian, the Demon Lord of the Abyss stood on the teleportation stone platform, and a white light flashed by, and the Demon Lord of the Abyss disappeared.
