With a wave of steel wings, Song Jian flew up and rushed towards the back of the Abyss Demon Lord;

Pulling out the broken heart of the Abyss Demon Lord from the big hole in the back of the heart, Song Jian whispered in the other party's ear: "I said, what I want is your flesh and blood!" ”

"Abyssal Blade Saphorans Kutua Sara......" Song Jian thought about the true name of the Abyss Demon Lord, and the demon heart in his hand, which was less than a third left, was beating violently as if he was frightened;

The Book of the Abyss appeared in front of Song Jian, the pages were windless and automatic, and a mysterious black aura spread from the book;

The Abyss Demon Lord listened to Song Jian recite his true name, and at the same time, the other party was still holding his heart in his hand, and suddenly felt bad in his heart;

"Human, what are you doing, do you think that heart is indispensable to me?" The Abyss Demon Lord was a little flustered, if it lost its heart, it would take at least a thousand more years for it to regain its peak state;

"Give it back to me!"

Because the Abyss Demon Lord's true name was too long, Song Jian thought quickly, but he couldn't stop the other party from rushing over to snatch the heart.

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

The Abyss Demon Lord could only scratch the light curtain with his hands in vain, causing ripples, but he couldn't break through this layer of defense no matter what;

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

Sneer~

At the center of its eyebrows, a blooming black lotus flower bloomed with dazzling light, and the Abyss Demon Lord let out a terrible roar, holding his head and tumbling to the ground;

Song Jian glanced at the demon heart in his hand, and released the shackle mark to consume some of it, and now there is less than a quarter of the entire heart left, and it is completely impossible to see that this flesh and blood mass is a demon heart;

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

"What have you done to me, what have you done to me, damn human, I'm going to kill you, kill you!" The Abyss Demon Lord roared loudly, and rushed towards Song Jian with teeth and claws;

"The mark, the pain!" Song Jian watched the giant-like abyss demon rushing towards him, without moving, standing in place, and snorting softly;

Suddenly, the Abyss Demon Lord felt a splitting headache, as if someone was wielding a sharp axe and constantly slashing his head, and it was as if a red-hot iron needle had pierced into his skull, constantly stirring;

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

The pain lasted for fifteen minutes, and the Abyss Demon Lord seemed to have lost all his strength, and collapsed to the ground like a puddle of mud, his body continued to twitch, and a trace of blood faintly appeared in his seven orifices;

"Don't, spare 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 take the treasure you want from that Qingyun Sword Gate!"

The Abyss Demon Lord finally couldn't bear this soul-tearing pain and begged Song Jian for mercy;

Song Jian smiled slightly, and with a movement of his heart, the Abyss Demon Lord suddenly felt the pain disappear;

"You, what did you do to me?" The Demon Lord asked weakly;

"It's nothing, it's just a few small tricks to make sure you follow the contract!" Song Jian lightly kicked the Abyss Demon Lord's shoulder with his toes and said, "Don't pretend to be dead, hurry up, recover your strength as soon as possible, as long as you help me destroy the Qingyun Sword Gate, I will cancel this shackle mark!" ”

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

"Do you think I'm an Abyss Demon!" Song Jian said disdainfully, turned around and walked towards the passage;

……

A month later, Qingyun Town, the closest town to the ruins, had been slaughtered, and not even a single body could be found in the entire town;

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

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

Until now, the power of the Abyss Demon Lord has finally recovered to the early stage of second-order combat power, and the level has also soared to fifty-one;

However, even though the strength of the Abyss Demon Lord surpassed Song Jian by a lot, the effect of the shackle mark in the soul did not weaken in the slightest, which also made the Abyss Demon Lord's impatient thoughts calm down in an instant;

"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'll go and get all the treasures back for you, as long as you can unlock my shackles!" The Abyss Demon Lord whispered.

"Forget it, it's still the Qingyun Sword Gate that matters!" Song Jian hesitated for a long time, but finally gave up this tempting idea;

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

Unless there are more powerful monsters hidden in the secret realm, however, if there really are such monsters, it is impossible for the Qingyun Sword Sect and the Chiyang Sect not to know about it until now;

The expiration of the shackle mark is only three months, and it will take a month for the strength of the Abyss Demon Lord to recover to the early stage of the second-order combat power, if you really want to go to the secret realm to explore the treasure, I am afraid that the time will pass quickly, and then Song Jian will have no means to restrict it, and the assessment task will be postponed indefinitely.

"It's a pity, this skill limit can only be used once for the same person, otherwise, I can let it stay with me all the time!" Song Jian muttered quietly;

"You teleport out from this teleportation array first, be careful, opposite is the back mountain of Qingyun Sword Gate, there are a few old monsters, I'm afraid you are not an opponent now, be careful lurking, and wait until you recover your strength, and then do something to them!" Song Jian pointed to the teleportation stone platform and commanded.

"Don't worry, the Abyss Demon is the race that is best at disguise, there is no one!" A smile appeared on the face of the Abyss Demon Lord, and his body shook like water waves, and after a while, he turned into the appearance of an evergreen river;

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