Zhang Ruochen is now at the peak of the Profound Extreme Realm, and the purpose of taking the Holy Liquid is not to break through the realm, but to use the holy power contained in the Holy Liquid to temper his physical body.

  Boom

  The holy liquid enters the body, like a bomb exploding inside.

  In an instant, Zhang Ruochen's Qi Lake, meridians and blood vessels were all filled with holy power, squeezing from the inside out, as if to burst his body.

  A wisp of sacred energy surged out from Zhang Ruochen's pores, transforming into white rivers that encircled and flew around him.

  Zhang Ruochen made a great effort to control the true energy inside his body and inject it into his soul meridian, stimulating his martial soul.

  The Martial Soul was like a tangible soul shadow, floating above Zhang Ruo Chen's head, looking exactly the same as him.

  Martial soul is also in breathing and exhaling, absorbing holy power, nourishing itself.

  Sacred power is the best supplement for martial souls.

  With Zhang Ruochen's current cultivation, it is impossible for his physical body to fully absorb a single drop of holy liquid, so he releases his martial soul, allowing the martial soul to also absorb the holy power.

  Under the impact of the holy power of the sacred liquid, Zhang Ruochen's aura lake was slowly expanding outward, becoming bigger and bigger. The aura lake contained more and more holy power.

  In general, Qi lakes can only expand when they break through boundaries.

  In just a short moment, Zhang Ruochen's Qi Lake capacity had doubled and was still continuing to grow.

  Twice, three times

  A whole day passed and Zhang Ruochen's Qi Lake expanded sevenfold before finally stopping.

  The lake of air expands, also meaning the cultivation is enhanced.

  If it weren't for the lack of resonance from all the gods, Zhang Ruochen would have thought that he had already reached the Supreme Realm of the Mystic Extreme Boundary.

  Zhang Ruochen's emotions were calm, continuing to refine the holy power of the sacred liquid, causing the holy power to merge into his bones, muscles, five organs, meridians, and blood vessels. His physical body was like a transformed sacred light treasure, every inch of skin emitting white light.

  A month later, Zhang Ruochen fully refined the holy power of that one drop of holy liquid with the true energy in his body, perfectly merging them into one.

  "The boundary has been raised, and with my current strength, I should be able to burst out at a speed of 80 meters per second. If I can cultivate the Wind Dragon Shadow to the Great Perfection boundary, the speed will definitely increase further, and it's possible that I can reach 81 meters per second."

  The Wind Dragon Shadow is a high-level martial skill that cannot be mastered overnight, requiring a lot of time to practice.

  "Zhang Ruochen, the 66 basic seals of the ancient sword have all been connected and completed, reaching the level of a 9th rank true martial treasure." Little Hei handed over the four-foot-long broken sword to Zhang Ruochen.

  "It's really great!" Zhang Ruochen was overjoyed in his heart.

  Zhang Ruochen grasped the hilt of the Xuan Yuan Ancient Sword and walked out of the inner space of the Time-Space Crystal, arriving in a vast courtyard.

  Standing in the center of the courtyard, carefully feeling this familiar sword, that feeling is like a family member returning to one's side.

  A warm current flowed into Zhang Ruochen's body.

  Man and sword, as if born of the same blood, merged into one entity.

  Clang

  The ancient sword emitted a sword hum, lightly quivering as if it had come back to life.

  Zhang Ruochen squeezed his eyes shut, utterly intoxicated. Gradually, the fingers that had been gripping the hilt of his sword slowly relaxed.

  The ancient sword did not fall to the ground and remained suspended in mid-air, motionless.

  Xiao Hei stood far away, his whole body hair standing on end, his eyes wide with wonder, and exclaimed: "Jian Xin Tong Ming"

  Fly

  Zhang Ruochen's mouth spat out a single word.

  Suddenly, the ancient sword flew out, carrying a long sword shadow. In an instant, it pierced the wing of a flying mosquito 100 meters away.

  "Whoosh"

  The ancient sword flew back immediately and fell into Zhang Ruochen's hand.

  "Haha, I've finally reached the state of sword heart clarity. From now on, follow me into battle as usual."

  Always unable to reach the sword heart clarity, did not think that after re-mastering the ancient sword of the abyss, instantly broke through the boundary.

  Zhang Ruochen held a four-foot broken sword in his hand, closed his eyes, and felt a grain-sized sword shadow in the air lake between his eyebrows.

  That is the "Heart of Sword Intention" that can be formed when one reaches the realm of Xīn Tōng Míng.

  Zhang Ruochen was able to reach the state of Sword Heart Transparency in the Profound Extreme Realm because he had once reached that state before, so it was naturally easy for him to cultivate back to that realm.

  Even if another martial artist were to reach the middle stage of "the sword follows the heart" in the Profound Extreme Realm, it would already be quite impressive. The realm of a clear and transparent sword heart is simply a legend to them.

  When reaching the state of sword heart clarity, one can control the battle sword through the mind of sword intent and kill enemies from a hundred miles away.

  Of course, Zhang Ruochen's current realm is still very low, and his true energy is not thick enough. At most, he can only control the flying sword within a hundred meters.

  Boundary breakthrough, Zhang Ruochen's temperament also underwent some changes, even if he was just standing there casually, giving people a faint sense of pressure, like a young sword god.

  If Zhang Ruochen launched an attack, even just a glance would be enough to crush the soul of a Huang Ji Realm warrior, scaring them off in disarray.

  "It's been only ten days outside, Kong Xuan estimated that he hasn't fully transformed his skills yet."

  Zhang Ruochen first went to Zhang Shaochu's residence and handed over the seven and a half sacred true liquids to him, then he went to Ziyan's residence.

  Zi Yan is practicing the Wind Dragon Shadow, and has already reached the entry level boundary.

  Speed was originally her strong point, and it's natural for her to grasp it quickly.

  She stepped on nine kinds of steps, extremely fast, like a beautiful illusion, just for an instant, she rushed to Zhang Ruochen's face.

  "Whoosh"

  Without warning, a sword light flew out of her sleeve, emitting a cold chill, stabbing towards Zhang Ruochen's neck.

  Zhang Ruochen didn't move his feet, he just slightly tilted his neck and easily dodged Ziyan's sleeve with the fish intestine sword.

  "Whoosh whoosh"

  Zi Yan successively stabbed out eighteen swords, leaving behind eighteen sword shadows. However, all of them were easily dodged by Zhang Ruochen, without even touching the corner of his clothes.

  Zi Yan sheathed his sword back into his sleeve, lightly biting his teeth, and asked: "You really haven't broken through to the Di Ji realm?"

  Zhang Ruochen shook his head.

  After leaving the Red Sky Secret Mansion, Zi Yan obtained a large amount of cultivation resources, and her cultivation base and physique were greatly improved. However, in front of Zhang Ruochen, she still felt a huge gap, and naturally felt somewhat disheartened.

  Zhang Ruochen seemed to see through Zi Cai's thoughts and said, "You are already very excellent. Even if you go to challenge the Xuanbang now, you can enter the top 800 of the Xuanbang. If you accumulate for another two years, entering the top 100 of the Xuanbang is not a difficult task."

  "But the gap between you and me is still too big"

  Zhang Ruochen said: "Your main problem is that your cultivation method is not profound enough, and the meridians opened up in your body are not enough, so you can't compare with me."

  The seventeen meridians in Zǐ Qiān's body were already quite excellent compared to other warriors, but compared to Zhang Ruò Chén, there was still a huge gap.

  Zi Yan said: "Is it that having fewer meridians in the body means one is definitely inferior to a martial artist with more meridians in their body?"

  "It's not necessarily so." Zhang Ruochen said, "A warrior's potential is infinite and endless. There is no factor that can absolutely determine a warrior's fate. It can only be said that one has the upper hand. I am now in the advantageous position, nothing more."

  Zhang Ruochen helped Zi Cai correct some mistakes in her steps and then left her alone to continue practicing.

  Zi Yan decided to cultivate the Wind Dragon Shadow to a small success before going to the Martial City Arena to challenge, preparing to charge into the top 500 of the Xuan Bang.

  Liu Chengfeng called out to Zhang Ruochen from afar and chased after him, saying: "Big Brother Master, someone wants to see you."

  "Who?" Zhang Ruochen asked.

  "The first on the list is Yan Lixuan." Liu Chengfeng said with some excitement.

  Zhang Ruo dust slightly furrowed his brow and curiously asked: "What did he want to see me for?"

  Liu Chengfeng said: "Big Brother, don't you know that during your closed-door training this time, your battle with Xun Guihai has spread throughout the entire Tianmo Martial City? Everyone says that you already possess the strength of the first on the Mystic List. Yan Lixuan, as the number one on the Mystic List, naturally wants to come and challenge you."

  Zhang Ruochen smiled and said, "What's the point of him challenging me? He's already the first on the Mystic List. Even if he defeats me, it won't increase his reputation. On the other hand, if he loses to me, wouldn't that be a loss of face?"

  Liu Chengfeng smiled and said: "Who knows what he's thinking, maybe he feels that being first on the Xuanbang list for too long is boring, so he actually hopes to be defeated by someone."

  Zhang Ruochen thought for a moment and nodded slightly, it's also possible that this might happen.

  At Zhang Ruochen's current level, he had lost interest in meeting Yan Lixuan, a warrior of that level, and didn't even want to see him. However, since Yan Lixuan had come to visit personally, as his junior, Zhang Ruochen still had to go meet him.

  Being able to become the first on the mysterious list, he must have his own advantages, and perhaps there will be unexpected gains.

  Yan Lixuan was a man in his sixties, wearing a simple linen garment. Although wrinkles had already appeared on his face and he looked somewhat aged, his hair remained jet black, without a single white strand.

  His arms were thick and sturdy, his body tall and majestic, full of spirit, yet standing there casually, gave people a feeling of being completely in harmony with nature, without any flaws.

  "The pinnacle of freedom."

  Zhang Ruochen sensed Yan Lixian's high state of being at first glance.

  No wonder he can become the first in the Xuanbang ranking, indeed he has real talent and learning.

  Decades of cultivation, although his martial arts realm is still the Profound Extreme Realm's Great Perfection. However, in terms of the realm of martial skills application, he is even more formidable than many Heavenly Extreme Realm warriors.

  If he were allowed to break through to the Earth Extreme Realm, he would quickly become a strong practitioner in the Earth Extreme Realm and might even reach the Sky Extreme Realm in a short period of time.

  Yan Lixuan's eyes lit up when he saw Zhang Ruochen, and he smiled slightly: "I thought that in the Xuanji realm, only I could reach the peak of freedom. I didn't expect you to also reach this state, truly a young man worthy of admiration."

  Zhang Ruochen hid the realm of Sword Heart Transparency. That's why Yan Lixuan thought Zhang Ruochen was only at the peak of Following One's Heart.

  Zhang Ruochen said: "I'm very curious, with your cultivation level, breaking through the Earthly Boundary shouldn't be a difficult task. Why haven't you broken through that boundary until now?"

  Yan Lixuan's eyes dimmed slightly, saying: "My heart of martial arts has a flaw, the knot in my heart cannot be untied, and the realm of martial arts will never be broken through."

  The knot in a warrior's heart is a very mysterious thing, which not only affects the warrior's mood but also influences their cultivation.

  For example, if a martial artist has done something that goes against their conscience, they will develop mental knots in their mind, which can hinder their progress in martial arts.

  For example, a warrior once made an oath but then went back on his word, which can also form a knot in the heart.

  Or perhaps a warrior has done something wrong and caused an irreversible tragedy, which would lead to intense remorse in their heart. This is also a kind of knot in the heart.

  Knots in the heart, there are many kinds.

  Some knots can be easily untied, while others are difficult to untie. Some knots have a small impact on martial arts, while others have a significant impact on martial arts.

  It's clear that Yan Lixuan's knot belongs to the kind of big knot, if the knot can't be untied, the martial arts realm will never be able to break through.
