In the spiritual world that is hard to reach with the naked eye, two incredibly powerful spiritual forces are entangled in an intense struggle, like two supreme masters engaging in a fierce and invisible battle.

  This was the most bitter and perilous battle in Xu Haifeng's life, even when he was in Wudang Mountain, Abbot Baiyun wanted to take his life, there were still Li Zhi and Xia Yajun, two great masters, to help him.

  However, at this moment, facing Cheng Xuanfeng, a veteran master who is three points stronger than Auben, he was alone.

  However, he was not intimidated at all. His mind was immersed in a wonderfully mysterious state, and whether it was his aura or his understanding of the spiritual world, he was already in no way inferior to this world-renowned Grandmaster.

  Cheng Xuan let out a silent sigh, deep down in his heart, he really didn't want to strike down the majestic and proud young man standing before him, at least not for now.

  Even with Cheng Xuanfeng's confidence and arrogance, even with the meticulous preparation of the Cheng family for decades, it would not be said that while dealing with the Xiongnu people, they could still extract any strength to deal with the Caesars.

  Once Xu Haifeng dies, the Black Flag Army under his command will not easily give up. It's likely that at that time, Xu Haifeng's previous threats to him will be put into action.

  Perhaps the only difference is that the leader of the Black Flag Army is not Xu Haifeng, but Jiang Kongming with his mysterious and unpredictable abilities.

  Ever since he saw the Zhuge divine crossbow created by Jiang Gongming, he had been extremely cautious of this person in his heart. If he thought about the various rumors about him again, he dared not have any slight underestimation.

  This person does whatever it takes, without any restrictions or taboos. In the Black Flag Army, aside from Xu Haifeng, he is also highly respected. Only he can mobilize the Black Flag Army when Xu Haifeng is not around. And yet, his sole object of loyalty is precisely Xu Haifeng.

  Perhaps this person is even more terrifying than Xu Haifeng.

  Once the Black Flag Army leaves Wulong City, it means that the Western defense line has completely collapsed, and the Caesar's army will enter the heart of the Great Han Dynasty like a broken bamboo, without any obstruction.

  The Western Eagle Legion was indeed a battle-hardened lion, but after all, they were not the Black Flag Army and could not create miracles of one against ten.

  The hidden power of the Cheng family is not as simple as it appears on the surface. Over the decades, relying on their strong economic strength, they have organized a large army that has been through many battles.

  The barbarians on the high mountains, the pirates in the vast ocean, are all their training opponents. Although they still lack experience in large-scale warfare, with Gu Dao Yan, this once-in-a-thousand-years genius commander, they can make up for this deficiency to the greatest extent.

  So he had confidence, able to defeat the Xiongnu, able to recover mountains and rivers, able to expel Caesar.

  But if the Black Flag Army intervenes at this time, all these grand ambitions will be nothing but a moon in the water, a flower in the mirror.

  Even if the Cheng family can successfully defeat the Black Flag Army, which is evaluated by Gu Dao as invincible with a million troops, they will inevitably suffer heavy losses. Once facing the mighty Xiongnu people and the well-prepared Caesar people, it's clear what the consequences would be without even having to fight.

  I fear that by then, those galloping across the Great Han territory will no longer be Han people, but rather these dregs of foreign tribes.

  His goal was to exterminate the Liu family, not to destroy the Han as a whole.

  In order to achieve this goal, a final showdown with the Huns was inevitable in the future. This fact was not only known to him, but also to the Huns and the Caesarians who had reached an agreement with him.

  The Han and the Xiongnu were originally two irreconcilable nations, with hundreds of years of border conflicts creating countless frictions and disputes that spawned endless hatred.

  No matter how great or strong an individual's power is, it cannot erase the gratitude and resentment engraved on the nation's seal.

  Cheng Xuanfeng can lead the family to achieve his own goals, collude with the Huns and use Caesar. However, he cannot push his own nation into the abyss, nor can he do it.

  Because he has always been a Han Chinese, a pure Han Chinese, an orthodox Han Chinese who takes pride in his own ethnicity.

  Xu Haifeng is where justice lies, there's no turning back.

  But he still had room for choice, because he was a strong man.

  This weathered old man finally showed a hint of hesitation in his eyes.

  "Hsss..." The ancient, unadorned Not-Breaking Divine Sword drew a beautiful arc, stabbing towards Cheng Xuanfeng.

  Although he didn't know why Cheng Xuanfeng's momentum suddenly weakened, Xu Haifeng, who was in the midst of it, clearly sensed his opponent's lingering doubts. If not now, then when?

  His sword was not fancy at all, one sword was just one sword, a forward thrust was just a forward thrust. He had concentrated all his skill and energy into this one sword. If Li Yanbo saw this sword with his own eyes, he would definitely be shocked, because this was simply the giant spirit palm in the form of a weapon.

  He has already been able to make connections and apply them flexibly.

  Such a powerful and intense sword strike, even an ordinary person can clearly feel the direction of this sword.

  Against a top master like Cheng Xuanfeng, any fancy moves would be useless. The only way to defeat him is to concentrate all one's strength on a single point and strike with full force.

  Cheng Xuan's heart skipped a beat as he sensed that this sword not only contained Xu Haifeng's full strength, but also his nearly peerless spiritual power, which was now charging towards him with the fatal blow.

  Whether in the material world or spiritual world, Xu Haifeng has already given his all.

  Rather be shattered jade than whole tile, only by putting it in a dead end, there is a thread of life.

  Fang Ming walked out of the imperial palace, nodded his head at Fang Lingde and said: "Second Uncle, I'll go ahead first."

  Fang Lingde grasped his hand tightly and asked: "Where are you going?"

  "Please send reinforcements." Fang Xing replied with a loud voice, jumped high and stood on top of a civilian house, looked around and identified the direction. He then ran at full speed with all his might.

  After running for a moment, suddenly there was a flash in front of his eyes, and then the wind rushed past his ears. He stopped abruptly, but found that there was nothing unusual in the air. Turning his head back to look, a black dot had already disappeared from view.

  Suddenly he felt something strange on his head, he slightly shifted his body, stretched out his hand and grabbed it, a piece of black cloth fell into his hand.

  He looked at the broken strip of cloth in his hand, feeling extremely familiar, with a thoughtful expression on his face, and a relieved smile appeared. However, he didn't stop, but instead accelerated forward, and disappeared from sight in an instant.

  Cheng Xuanfeng concentrated his spirit to meet him, one of his palms slowly and quickly lifted up, his whole body's power rose to more than 80% in an instant, also welcomed him without any fancy moves.

  "Hiss......" The sword and palm intersected, emitting a low, muffled sound.

  Xu Haifeng was struck by lightning and his body flew backwards.

  Cheng Xuanfeng was at a disadvantage because he hadn't gathered all his strength, and the slight distraction earlier had caused him to launch a hasty attack. Neither his mental energy nor his skills were in their best state.

  For him, this was an unforgivable mistake. If it were another master of the same level, that one move would have been enough to leave him severely injured.

  Fortunately, Xu Haifeng had just entered the realm of the grandmaster, and his cultivation base was still a distance away from Cheng Xuanfeng, who had dominated the world for decades.

  However, his spiritual power was obviously above the standard, and under the sudden attack, even Cheng Daizong also suffered a lot.

  Cheng Xuan's brows were tightly furrowed, the veins on his temples bulging with rage, and despite his usual composure, he couldn't help but mutter a curse under his breath.

  Exchanging blows with a master-level expert, he still dares to have reservations in his heart and dares to slack off; what's the difference between that and seeking death?

  Xu Haifeng's feet touched the ground, and he immediately borrowed strength to rise into the air again, pouncing upwards once more. The continuous combat ability of Jing Xin Jue was unmatched in the world. In this brief moment of retreat and advance, he had already re-condensed an aura of might that was not inferior to his previous full-strength strike.

  Cheng Xuan let out a low sigh, took a deep breath, and the true energy inside his body circulated ceaselessly, like a raging sea with waves upon waves. In an instant, he had already completed nine cycles within his body.

  The Yangtze River has three layers of waves, each wave is higher than the previous one.

  Compared with Cheng Yingtao, his set of Three Chords of the Yangtze River is the real one that can destroy all things in the world.

  In an instant, just that brief moment of effort, and the Nine Revolutions were already complete.

  Cheng Xuanfeng showed no mercy in his attack, unleashing the full force of the Three Waves of the Yangtze River, condensed from the Nine Turns of the Mysterious Tao.

  Xu Haifeng's body slowed down strangely in mid-air.

  The space around him suddenly became an endless ocean, with waves crashing down on him with all their might.

  Xu Haifeng was like a carp swimming upstream, constantly moving forward, and with each step forward, his strength was consumed a little, his spirit was exhausted a little.

  However, his figure has been stable from start to finish, so strong, so persistent, he never gave up, no matter how many obstacles are in front of him, no matter how many dangers are blocking his way.

  He knows but does not fear, never speaks of giving up.

  Jumping through the Dragon Gate, one can only be reborn and transformed into a dragon, looking down on the world, soaring in the sky above the nine heavens.

  The unbroken divine sword in his hand finally split open the countless air waves that seemed to have substance in front of him, stabbing into Cheng Xuanfeng's chest.

  A loud explosion sounded, and Xu Haifeng flew back once again.

  This time, he was already exhausted. The sword just now had drained the last bit of internal energy from his body, and he stood there, although still standing upright, but his whole body was weak and limp.

  Cheng Xuanfeng slowly lowered his head, the white clothes on his chest cracked open, and a faint thread of blood seeped out from within.

  "Thirty years... and I'm still wounded for the first time. Indeed, heroes emerge in their youth." Cheng Xuanfeng sighed.

  Xu Haifeng was taken aback and lost his smile, just as he was about to respond, when suddenly he seemed to sense something, looked up and gazed into the distance.

  Almost at the same time, Cheng Xuanfeng's gaze also turned in the same direction.

  A tall and majestic figure descended from the sky, his face stern and cold, with an aura that pierced the heavens. He held in his hand a rare and extraordinary outer gate weapon - the Crescent Moon Spade.

  He was the only master-level expert in the Black Flag Army besides Xu Haifeng, Li Mingtang, who had once died and come back to life.
