Ning Yuan quickly arrived at the Fourth Prince's residence and saw Lan Feng reading in the study. With a solemn expression, he strode into the study, waving to the servants behind him to leave. After they had all departed, he gently closed the door and secured it. Turning around, he took a deep breath and slowly said, "Fourth Brother, I have something extremely important that I need to discuss with you in detail."

Lan Feng, sitting behind his desk, slightly raised his head, looked at the serious-looking person in front of him, and calmly replied, "Oh? What is so important that it makes you so nervous?"

Ning Yun lowered his voice, quickly walked to Lan Feng's side, and whispered in his ear: "Fourth Brother, according to reliable sources, the Crown Prince is preparing to take action against you! The time is set for the third day of next month, which is the day you go to the outskirts of the city to reward the soldiers."

Upon hearing this news, Lan Feng abruptly stood up, clenching his fists, a flash of surprise and anger in his eyes. He raised his voice and asked, "Is this true? Is the Crown Prince so intolerant of me that he intends to take my life so soon?"

Ning Yun nodded quickly and comforted him, "Fourth Brother, don't be angry. Hua Yu learned about this by chance and then told me. She knows that you are engaged to Hua Xiang and it is inconvenient for her to have any contact with you, but she is worried about your safety, so she asked my uncle and me to come up with a plan for you."

Upon hearing the name "Hua Yu," Lan Feng's heart skipped a beat, and a complex mix of emotions welled up within him. He recalled the moments he had shared with Hua Yu, and a wave of guilt washed over him as he silently reflected that he truly felt he had wronged her.

"Congratulations, host! You have completed the 'timely help' mission and earned 10 points. You provided Lan Feng with this important information, which has made Lan Feng grateful to you and greatly increased his favorability. You have now accumulated 90 points. You are amazing, my host." Xiao Zha reported the progress while switching between scenes of the Fourth Prince's mansion.

"Haha, don't you know who I, Ruan Quan, am? A woman who's strong-willed her whole life, I will never lose!" Ruan Quan excitedly danced around, celebrating that her conquest mission was almost complete.

"When Lan Feng and Hua Xiang get married, that will be the day I complete my revenge. I'm really looking forward to it!" He then gave a wicked smile.

Meanwhile, on Lan Feng's side, Ning Yuan and Lan Feng were discussing how to launch a brilliant counterattack against the Crown Prince on the third day of next month, and they made a detailed plan.

"Fourth Brother, on that day, I'll go to the outskirts of the city in your place. You can lie in ambush in the shadows and wait for the Crown Prince's men to appear. Then we can coordinate from the inside and outside to catch them off guard. What do you think?" Ning Yun looked into Lan Feng's eyes and said earnestly.

"I think this plan is excellent, so let's make it that way."

Time flies like an arrow, and in the blink of an eye, it was the third day of the following month. Ning Yuan, dressed in a black, fitted outfit that accentuated his tall, agile figure, held the long sword at his waist, its hilt gleaming with a power that seemed ready to be unleashed. At first glance, his cold, stern expression was strikingly similar to Lan Feng's. This time, he was accompanied by a carefully selected group of followers, escorting a cart laden with rewards and supplies. The wheels rumbled as they steadily made their way towards the outskirts of the city.

Upon reaching Black Wind Gorge, the sheer cliffs on both sides rose abruptly from the ground like monstrous beasts, towering into the clouds. Sunlight was completely swallowed by the treacherous mountains, leaving the valley dark and deep. A cold wind, carrying the stench of decay, howled and whistled through the air, causing the flags to flutter like the wails of demons. Ning Yuan frowned; his years of martial arts training honed his keen intuition, instantly triggering an alarm. He thought to himself, "They're here!" Before he could even raise the alarm, a large number of bandits surged out from all sides. The bandit at the head of the group, his face smug and arrogant, shouted at the top of his lungs, "Capture Lan Feng! The chief has ordered that he must not return alive; he must die in this Black Wind Gorge!"

Ning Yuan's lips curled into a disdainful sneer. With a clang, he drew his sword, its cold light flashing like silver lightning breaking through ice. "Wishful thinking! You think you're worthy to block my path?" With that, he charged into the enemy ranks like a ghost. Seeing this, his followers were filled with righteous rage and drew their swords to follow. In an instant, the sounds of metal clashing and shouts of battle shook the valley as the two sides clashed.

The Crown Prince's men were clearly well-trained, their attacks perfectly coordinated, a relentless barrage of strikes, and they held an overwhelming numerical advantage. Ning Yuan and his group were quickly plunged into a fierce battle. His close associates fell to the ground, screaming in agony, blood gushing forth, staining their clothes and the ground beneath their feet. But Ning Yuan showed no fear; his eyes gleamed with an even colder light. His swordsmanship was expansive and powerful, the blade flashing like a dragon emerging from the sea, each move carrying deadly force.

In the heat of battle, Ning Yuan caught a glimpse of a natural ravine on one side of the canyon, its terrain concealed. He instantly devised a plan to lure the enemy. Feigning exhaustion, his swordsmanship faltered, he retreated hastily, shouting in feigned panic, "Brothers, we can't hold on! Retreat!" This lured the enemy into pursuit, intending to wipe them out. Once the group was near the ravine, Ning Yuan's eyes widened, and he suddenly unleashed his power, roaring, "Attack!" His longsword unleashed his signature move, "Wind-Breaking Slash," the blade's energy surging and seemingly tangible, instantly felling a group of enemies.

At the same moment, he shouted hoarsely, "Light the fire!" It turned out that before setting off, Ning Yuan and his entourage had scouted the location and planned the operation multiple times, ordering people to bury a large amount of gunpowder in a secluded spot in the mountain valley under the cover of night, with the fuse winding and hidden. Upon hearing the order, his entourage quickly took out tinderboxes, lit the fuses, and after a "sizzling" sound, the ground shook instantly.

Just as Ning Yuan and his men were struggling to hold on and were beginning to feel the strain, a rapid clatter of hooves suddenly came from above the canyon, like a series of drumbeats, causing the ground to tremble slightly. Everyone looked in the direction of the sound and saw Lan Feng, dressed in black, leading a troop of elite cavalry, charging towards them like a divine warrior descending from the heavens. Lan Feng was agile and stern-faced, wielding his spear with fierce power, and shouted loudly, "Fifth Brother, don't panic, I'm coming!"

Lan Feng charged ahead, plunging into the enemy ranks. Wherever his spear touched, enemies fell. His spearmanship was fierce and precise, sometimes thrusting straight for throats, sometimes deflecting weapons, instantly disrupting the enemy's formation. The cavalry he brought were also well-trained, quickly coordinating with Ning Yuan's personal guards to launch a pincer attack on the enemy.

Seizing the opportunity, Ning Yuan brandished his longsword, raised his arm, and shouted, "Brothers, charge back!" Leading his remaining followers, they charged back like tigers descending a mountain, unstoppable. With each stroke of their blades, they reaped the lives of their enemies, routing them and leaving them in complete disarray.

Just as the tide of battle turned and victory seemed within reach, a cold arrow, whistling through the air, whistled towards Lan Feng's throat. As if he had eyes in the back of his head, Lan Feng dodged, the arrow grazing his cheek and leaving a bloody mark. He looked up, his sharp gaze instantly locking onto a treetop, where a black-clad guard was concealed, nocking a bow and aiming, preparing to fire again. Lan Feng's eyes narrowed. He bent down, picked up a stone, channeled his inner strength, and hurled it. The stone, like a cannonball, struck the guard's wrist precisely. With a "crack," the bow and arrow fell to the ground. Immediately afterward, he lightly touched the ground with his toes, leaping onto the tree trunk with lightning speed. In a few swift moves, he locked onto the guard's vitals and captured him alive.

After dealing with the hidden guards, Lan Feng led his men to reorganize the battlefield and tally the casualties. The Crown Prince's men were mostly dead or wounded; the remnants fled in disarray, abandoning their armor and weapons. Lan Feng ordered several prisoners to be bound alive, his gaze icy: "Take them back and interrogate them thoroughly. I want to see what other tricks the Crown Prince can pull!" Once the reward procession was reorganized, he dusted off his clothes, smoothed his disheveled hair, and his gaze was resolute: "Let's go. The soldiers in the suburbs are waiting for us. Today's rewards will not be shortchanged!" With that, he waved his hand and led his men towards the suburbs in the afterglow of the setting sun, his figure growing even taller and more imposing. Ning Yun, meanwhile, reined in his horses, watching Lan Feng's departing figure, nodded slightly, and led the remaining cavalry to clear the battlefield before quietly withdrawing his troops.
