"I thought killing was my heart, but I was wrong. Ling Feng raised his head and stared at the blood mark in front of him, the fifteenth blood mark, the sixteenth blood mark wanted to break free from the fifteenth blood mark, but there was nothing he could do, it seemed to be hindered by a layer of diaphragm, and there was also a layer of diaphragm in Ling Feng's heart.

"Killing, is the way I want to go, but also my heart, I will not resist killing, but I will not blindly pursue killing, cultivating immortals, my hands will inevitably be stained with blood, but, this is not my real heart, cultivating immortals must kill, but it does not mean that killing is my heart. Ling Feng fell into deep thought, staring at the fifteen blood seals suspended in front of him: blood, evil, underworld, soul, secluded, prison, crime, punishment, refining, punishment, precept, evil, demon, slaughter, killing, these fifteen blood seals were suspended and hovering around Ling Feng, and the rich smell of blood enveloped the cave, killing ..... The heart of killing, whether it is really your own heart.

He is not afraid of killing, because he has been used to killing since he was a child, for money, for power, one by one mortals betray their relatives and kill their friends, in the world of cultivating immortals, for a magic weapon and strange things, friends who have been together for a hundred years can turn against each other, and relatives and brothers who have stepped into the immortal road together can be killed by themselves, the world is full of things, everything is ugly, Ling Feng has long been used to it.

That's right, I've been used to seeing it for a long time, but it's not that I like to kill, the experience of my childhood, my three years of life in Tianyinguan, all of this made Ling Feng's heart breed a little dissent, that's right, he hated, he hated it, he hated this piece of heaven, it was this way of heaven, and those people or demons killed on the road of cultivating immortals were just tempering on the road of cultivating immortals, his ultimate enemy, the things he finally wanted to kill, it was this day, himself.... It's going to be a reversal of this day!

Why can some people be born in those famous families, the great religion of the ages, they have superior conditions when they are born, and the road to the immortals is smooth, and others have worked hard to reach the realm that they have only reached after stepping through the mountains of corpses and the sea of blood, those people may only need to stay in the sect and cultivate silently, and with the assistance of natural qualifications and various spiritual objects, they can easily reach the realm that others dream of in their lives, why? Why can they regard other people's efforts as dung, why can they easily trample on the dignity of a person, because they have strength, they are the pride of heaven, the darling of heaven, and more people on this vast land are from mediocre backgrounds, and may not be able to contact the immortal path in their lives, why are these people so far behind others? Born by heaven, the immortal road is broken by me, and the heavens are fair? No, how can the way of heaven be fair? Mortals believe in the sky, sacrifice to the sky, but they don't know, if you want to really find great freedom, great freedom, you must embark on a bloody road with the sky, and the earth, this day from the beginning is the enemy of the immortal cultivators, the road ups and downs, the way of heaven dominates, generation after generation of power is not afraid of the sky, brave and the sky, not afraid of the sky, not afraid of the earth, let the heavens descend many disasters, still indifferently faced, only for the end of the ethereal fairy road, endless years, across the eternal time, the stars change, the vicissitudes of the sea, and the eternal unchanged is the eternal belief that wants to fight with the skyHeaven does not treat me, why should I wait for heaven? Kill! Kill! Kill! Kill all those who block my way, kill all those who go against my path, kill this sky, cut through this eternal heavenly reincarnation, and kill a fairy road!

"My heart..... It turns out that this is my true heart. Ling Feng slowly opened his slightly closed eyes, the temperament of the whole person changed dramatically again, murderous and indifferent, sharp and calm, everything seemed contradictory but compatible with each other, a seven-colored streamer flashed in his pupils, the whole person looked extremely ethereal, indifferently watching the affairs of heaven and earth, drawing his sword to cut off all the heavens, earth and people! At this moment, Ling Feng could be regarded as truly understanding his heart.

Enlightening one's own heart is a part of the immortal cultivator's journey on the immortal road, which has nothing to do with strength, some people may not have stepped into the immortal road to realize their own heart, and some people may not have realized their own heart in the empty underworld, but it is certain that those who understand their own heart may not be able to become strong, but those who do not know their own heart are also unlikely to achieve much on the immortal road.

"This blood mark.... It turned out to be so simple," a smile appeared on the corner of Ling Feng's mouth, but the fifteenth blood mark in front of him, which was constantly distorting, calmed down at this moment, and soon, another new blood mark peeled off from the fifteenth blood mark, forming on its own, turning into a "barrier" character mark suspended in mid-air.

"The seventeenth path, the eighteenth path, I see, although the art of blood refining also tests talent, strength and physique, the most important thing is the Dao heart, a killing heart, this killing heart does not refer to the heart of killing, but the heart of rebellion. Ling Feng's smile became brighter and brighter, he truly comprehended the true meaning of the predecessor who created this, if he wanted to condense the eighteenth blood seal, he must have a Dao heart that dared to fight in the sky, since he dared to fight in the Heavenly Dao, how could all kinds of killings on the path of cultivating immortals be terrifying, with this heart, it could be regarded as having a real killing heart.

When the eighteenth blood seal "kill" is condensed, the remaining seventeen blood seals bloom at the same time with a brilliant seven-colored brilliance, blood, evil, underworld, soul, ghost, hell, crime, punishment, refining, punishment, precept, evil, demon, slaughter, killing, obstacles, sins and other seventeen blood seals, and at the same time around the last blood seal, "kill" Beside the character seal, eighteen blood seals were reflected in rings, forming a series of strange formations, following Ling Feng's divine sense control, these eighteen blood seals also slowly merged into the soul bell, and suddenly, countless blood-colored lines appeared on the originally black soul bell, and a bloody aura was released, filling the entire cave.

"Huh! The sacrifice is finally completed, and the process of this sacrifice is even more tiring than fighting with a great demon in the late stage of the Dao realm. "The Soul Bell Sacrifice was completed, and Ling Feng finally breathed a sigh of relief, not to mention anything else after the sacrifice along the way, the Qi Recovery Pill alone consumed five bottles, fortunately, the Feng Evil, Wu Mo and others who Ling Feng had killed were well prepared to restore their true strength, and these five bottles of pills were nothing.

Although he was physically and mentally exhausted, Ling Feng was undoubtedly excited in his heart, refining the Soul Bell was not a real gain, after all, the Soul Bell was just an experiment, what he really needed to refine was the black knife and the Spiritual Light Mirror, for Ling Feng, the real gain this time was to understand his true heart, although he did not increase his strength for the time being, but he made his future immortal path more open, and the Dao was clearer.

"It's been a long time since I've been so tired, so let's rest for a while. Ling Feng closed his tired eyes, eighteen blood marks merged into the soul bell, and the cave fell into darkness again, without a sound.........
