A promise made must be kept for a lifetime.

  "You've actually been sneaking up on me all along, and Yue Hongyan and the others have become even more lax."

  The young man in white clothes lifted his hand with difficulty and wiped the sweat from his forehead, coughing repeatedly.

  But his seemingly weak body suddenly burst out with an astonishing surge of magical power, driving the golden sandy sea beneath him to violently shake.

  Lin Feng was still in a state of stealth at this time, and with the system's concealment of his cultivation, it should have been impossible for him to be discovered so easily.

  "It's all over." As soon as the other party opened his mouth to speak, Lin Feng knew something was wrong and subconsciously looked down at the sandy ground under his feet.

  This golden sandy ground obviously has a very strong detection ability. Once an outsider invades, it will immediately produce a sensation, letting the young man in white know.

  Through this sand, the white-clothed youth was unable to see through the system's disguise and could not detect the strength or weakness of Lin Feng's internal energy, but he could clearly feel that someone had stepped onto the sandy ground.

  There are outsiders breaking in, but they themselves did not realize it, which is enough to illustrate the problem.

  So the young man in white immediately took action.

  The yellow sand swirled up in the sky, about to engulf Lin Feng.

  Lin Feng's eyebrows slightly furrowed, the Black Cloud Flag shook once, and his entire body was enveloped by a cluster of dark light. The dark light flashed, isolating the yellow sand outside.

  "Jindan period artifact? But it's damaged and can't stop me." The young man in white robes weakly raised his hand, slowly forming a spell seal.

  A stream gushed out from the sandy beach, shooting a water arrow that merged with the yellow sand, instantly turning into a dull and turbid current, flying towards Lin Feng.

  Lin Feng's mouth was bitter, and his opponent had not used all his strength, but he had already revealed the powerful strength of the Golden Dan period.

  That murky yellow water flow actually broke through the defense of Hei Yun Qi Wu Guang with ease, and pounced straight at Lin Feng.

  Lin Feng's eyes flashed: "The sand grains are heavy and condensed, one grain of sand may weigh thousands or even tens of thousands of catties, enough to crush a mountain rock, but it has been compressed into the size of a sand grain. This time, there are tens of thousands of them attacking me!"

  "The sand grains are heavy, but they are rolled up by the water flow, merging into the water's dynamic changes, with unpredictable trajectories that are difficult to avoid. Even if I dodge, the water flow will change direction and chase after those thousand-pound sand grains."

  The young man in white clothes combined the thickness of the earth with the agility of water in this move, truly a profound and mysterious technique.

  The defensive barrier of the Black Cloud Flag was breached, but Lin Feng remained calm and continued to drive the flag's power to conceal his body shape. However, in secret, he had already unsealed the Heaven-Imprisoning Seal that bound the Swallowing Heavens Infant.

  "What the heck is this thing?!" Swallowing hard, he could only helplessly block Lin Feng's gun again, transforming back into his original form and laboriously swallowing down the dark yellow liquid.

  "Ugh... Cough, cough, cough! I'm choking to death!" Tongtong roared in anger: "Lin Feng, you bastard, if you make me eat these messy things again, I'll fight you to the death! What the hell are these things, they're killing me!"

  Lin Feng smiled slyly: "Having something to eat is good enough, at least I still think about changing the style for you often."

  Swallowing sounds filled the air, Lin Feng's ears were deaf to them, and once again he sealed Swallow with the Heaven's Cage Seal.

  "You're going to swallow your own words one of these days!" Tuntun rolled her eyes, now she was clearly having indigestion, her stomach hurt badly, even if she didn't have the Heavenly Cage Seal, for a while she couldn't stir up any waves.

  His own magic was unexpectedly dissolved by the opponent without a sound, and the white-clothed youth's eyes flashed with precision. His waist, which had been arched due to illness, straightened slightly.

  Lin Feng saw this and furrowed his brow, speaking first: "Are you injured?"

  The young man in white coughed twice: "No need for you to worry, what's the ability, let's go, Kang Nanhua will follow."

  Lin Feng put away the Black Cloud Flag, revealing his true form. With a wide and large sleeve, he activated his Intimidating Aura Mode and said proudly: "I never take advantage of others, let alone bully you, a junior with injuries."

  Kang Nanhua, a young man in white clothes, looked up at Lin Feng without saying a word.

  At this moment, Lin Feng's white robe with wide sleeves and his feathered crown made him look like a celestial being. His demeanor was high and proud, yet he seemed completely at ease, as if he were truly an extraordinary person from another world.

  He looked at Kang Nanhua and calmly said: "I have nothing to do with the Great Zhou Imperial Court, you don't need to be so careful."

  "To be honest, there are even some frictions between me and the Great Zhou Imperial Court."

  Kang Nanhua wiped the cold sweat from his forehead and said slowly: "I'd like to hear more about it."

  Lin Feng said: "One of my disciples is the son of Zhu Hongwu, the mysterious Marquis of the Great Zhou Dynasty."

  Kang Nanhua was displeased: "You're just playing with me emotionally."

  Lin Feng's expression was calm: "If you knew that my disciple almost died at the hands of his own father, you wouldn't think this way."

  Kang Nanhua's eyes flashed with a hint of surprise: "Half a year ago, Xiao Hei and others attempted to kidnap one of Zhu Hongwu's illegitimate sons, but failed. They were rescued by Huang San from the Xuanji Marquis' manor, but afterwards, news came that the illegitimate son and Huang San had gone missing together."

  "Does he mean Zhu Yi, a bastard son? Is that who you are referring to?"

  Lin Feng smiled calmly: "A month ago, in the southern forest of the Great Qin Empire, I had just eliminated Tao Er, one of Zhu Hongwu's two deputies. He wanted to harm my disciple, so I took action and eliminated him."

  Kang Nanhua remained silent, his eyes flashing with unknown thoughts.

  After a long while, Kang Nanhua spoke up and asked: "What brings you here?"

  Lin Feng said frankly: "I came here to find a kind of mineral called Star River Sand."

  "How much does your lordship need?"

  Lin Feng was overjoyed in his heart: "There really is Star River Sand here!" But when Kang Nan Hua asked him how much he wanted, this question stumped Lin Feng - who knew how much Star River Sand was needed to repair that broken mirror?

  Lin Feng hesitated for a moment before asking tentatively: "Yi Li Fang, are you here?"

  Kang Nanhua furrowed his brow: "There's no way I can give you that much."

  Lin Feng's eyes narrowed slightly, and what Kang Nanhua had just said was "can't give you that much", rather than "don't have that much". This meant that he actually had more than one cubic meter of Xinghe sand in his hands, but was unwilling to give Lin Feng that much.

  Lin Feng's mind was racing with thoughts, he had no grudges or grievances against the other party, and it wasn't worth risking his life to fight them. If he could obtain the Xinghe Sand through a trade, that would be for the best.

  Just as he was thinking about it, Lin Feng suddenly felt something moving in his arms.

  Lin Feng quietly checked it out and found that the unusual thing was none other than the stone flute handed over to him by Meng Yi on that night.

  Since Lin Feng obtained the stone flute half a year ago, he had been pondering over it but to no avail, making him suspect that the mysterious woman from that night was deceiving him.

  Unexpectedly today, facing Kang Nan Hua, I suddenly felt a movement.

  Could it be that this pale-faced young man in white is somehow connected to this stone flute?

  Lin Feng quietly took out the stone flute and observed it secretly, only to discover that there was a strange and mysterious fluctuation of magical power within it, causing it to tremble slightly.

  That surge of magical energy spread out and came into contact with Kang Nanhua, and the pain-wracked Kang Nanhua suddenly felt a jolt of spirit, only to feel that his old wounds, which had been as irritating as a maggot attached to bone, had eased up considerably.

  Kang Nanhua looked at Lin Feng in surprise, seeing him like this, Lin Feng was also secretly surprised: "Can this stone flute really treat his injuries?"

  Lin Feng felt a lot more at ease after realizing this, but he still didn't dare to be careless: "Now that I have this chip, it will be much easier for me to haggle with him, but this person is already so powerful even when injured. If his injuries were to heal, wouldn't it be even harder to deal with him?"

  Lin Feng thought for a moment and decided to try to get more information out of him first, seemingly casually asking: "Are you also a refugee from Snow Wind Country?"

  "No, it's not like that." Kang Nanhua shook his head: "If I really had to say it, I can actually be considered a child of the Great Zhou Dynasty."

  Lin Feng was slightly startled, and a hint of reminiscence appeared in Kang Nanhua's eyes: "My parents were both commoners under the rule of Great Zhou. Before I learned Taoist cultivation, I also studied poetry and books hard, and even passed the imperial examination as a scholar of Great Zhou."

  "Then why are you now an enemy of Zhou Jun? Did your family members die at the hands of the Zhou people?"

  Kang Nanhua shook his head: "My parents both lived to the limit of their natural lifespan and left the world without any suffering. I have achieved my studies, although I wanted to extend their lifespan for them, but in the end it was not possible. However, both elderly people lived to be over a hundred years old, there's nothing to regret."

  Lin Feng's eyes flashed: "Is your lover in this fierce wind?" He thought of that fiery girl, Yue Hongyan.

  Setting aside her strong and straightforward temper, she is truly a beautiful but troublesome girl, absolutely a calamity.

  Kang Nanhua seemed to know what was on his mind, and smiled: "Have you seen Hong Yan? Hehe, although I don't reject the feelings between men and women, but after cultivating until now, I haven't met a member of the opposite sex that moves my heart, including Hong Yan."

  "Who would believe you?" Lin Feng muttered to himself, asking: "Then why are you helping Lie Feng Hui?"

  Kang Nanhua said calmly, "Yue Hongfeng, one of the founders of Lie Feng, was a sworn brother to me. Before he died, he entrusted me with protecting his comrades, and I agreed."

  Lin Feng's pupils suddenly contracted, his eyes fixed tightly on Kang Nanhua.

  The young man in white, although tortured by pain and covered in cold sweat, remained calm and composed, without any complaints or hint of pride, as if he was just doing something that came naturally to him.

  His voice was so calm, as if opposing the mighty Zhou Dynasty was a normal and reasonable thing to do, like eating and sleeping.

  Not to mention Zhou Emperor Liang Pan, Xuanji Hou Zhu Hongwu and other powerful heroes, not to mention the ruthless killing machine of Shenwu Army, even Tao Er and Huang San, who were in charge of the Xuanji Hou Mansion, were also Jindan period cultivators of the same level as him.

  Confronting such forces, he could die at any moment, but Kang Nanhua seemed to be oblivious to all these dangers.

  Even if he himself is already beset with pain.

  Everything is just because he promised his old friend and made a commitment, so he must keep his promise.

  No matter how thorny the road ahead is, with knives and fires everywhere, I promise to do what I have promised, even if it costs my life.

  Lin Feng looked at Kang Nanhua, and for some reason, a sentence suddenly appeared in his mind.

  "A promise made to one person must be kept for a lifetime!"
