Discovering the target, both of them were excited and raised their sniper rifles, observing through the scopes. Luo Zheng didn't recognize them; he saw a group of Westerners, among whom was an Easterner, about fifty years old, resembling a university professor. He couldn't help but lower his gun in confusion and turned to Lan Xue, asking, "Is it them?"

"No mistake," Lan Xue said with a livid face, her eyes filled with towering hatred.

Luo Zheng became puzzled, wondering why Lan Xue hated them so much, but he didn't ask further and said, "What's next? Is the Easterner their leader?"

"Remember, that Easterner is a traitor. It would be best to capture him alive, otherwise, he must be killed," Lan Xue said through gritted teeth, her killing intent growing stronger. She put down the sniper rifle, turned to Luo Zheng, and earnestly instructed, "If I die, you must kill that Easterner, understand?"

"Can you tell me why?" Luo Zheng asked in surprise.

"A traitor, carrying national strategic secrets, must be killed," Lan Xue said coldly, her face as icy as severe frost, emotionless, and continued after chambering a round, "Remember this place, we'll split up and encircle them, fight separately. If we get separated, meet back here."

"Alright," Luo Zheng's fighting spirit erupted, and he readily agreed. Thinking of his brothers' vengeance, he didn't hesitate and decisively walked away, his steps firm and powerful.

"Remember, stay alive," Lan Xue suddenly said.

Luo Zheng paused, turned around, and saw a glint of concern in Lan Xue's icy eyes. His heart was touched, and he nodded firmly, saying, "Stay alive."

Speaking of which, he walked away to the side. Battle and killing were tense and panic-inducing for new recruits, with many too afraid to face them. Luo Zheng's mind was filled with hatred, and having experienced several death threats and even killed a man with a stray bullet, he didn't feel any negative emotions. He quickly found a seemingly sturdy tree with a higher elevation and many trees in front for cover. According to Lan Xue, this terrain was not easy for the enemy to target. The side of the big tree had lower terrain, a natural trench. Luo Zheng quickly lay down, coldly raised his gun, and rapidly searched for targets through the scope. He soon locked onto one, able to clearly see the opponent's appearance. The distance was somewhat far, and Luo Zheng couldn't judge the exact distance, only make a rough estimate, desperately recalling the shooting skills Lan Xue had taught him. Normally, the trajectory of a bullet after being fired is parabolic. Handgun bullets produce visible deviations at 15 meters, and rifles around 70 meters. Therefore, depending on the distance, the bullet might land at any point on the crosshair's vertical line. As a sniper, it's not enough to just place the enemy in the crosshairs; the sight is not a guide but a reference. To accurately hit the target, a sniper must accurately estimate the distance. Besides distance, factors such as wind speed, visibility, light refraction, and the magnification and lens quality of the optical sniper scope can all affect sniper accuracy. Luo Zheng had learned a lot of relevant knowledge from Lan Xue but lacked practical experience. It was his first time touching a sniper rifle, and he hadn't fired a single bullet, feeling completely uncertain. After aiming for a while, Luo Zheng still couldn't determine if he could hit the target. Suddenly, he remembered Lan Xue's advice to fire like a 'clay pigeon shooter' if he felt uncertain. He decided to let go of all thoughts and focus on aiming carefully. Within a hundred meters, Luo Zheng could hit wherever he pointed. This time, the enemy was over a thousand meters away, and he had to consider the lead for his own people differently. Luo Zheng thought for a moment and roughly judged the shooting position based on factors like wind and light. He focused and felt uncertain, shifted a bit, still uncertain, shifted again. After correcting about ten times, Luo Zheng still felt uncertain. Suddenly, he heard a gunshot, his heart jumped, and he reflexively pulled the trigger. Through the sniper scope, he could see the shocking and astonishing scene of the sniper bullet roaring out. Then, Luo Zheng saw a person being blasted away, with a spray of blood from their chest. Luo Zheng guessed that the shot was fired by Lan Xue. After a careful search, he saw a person with a blown-up head, and the others fled quickly, all hiding in the woods and disappearing. Luo Zheng knew he had lost the initiative, and what followed was a fight to the death. Fortunately, he had accidentally hit one person, which was something to fall back on. The enemy was very powerful, and rushing in would be suicidal. Luo Zheng decided to stay hidden and not move, searching left and right. He realized there was no better sniper position and steeled his heart, abandoning the idea of moving, even though it went against sniper common sense and was the most likely to be discovered. Before long, Luo Zheng heard gunshots from the opposite side, knowing that Lan Xue was battling the enemy. Staying hidden here felt somewhat like cowardice, but after thinking it over, Luo Zheng decided to remain still, adopting a 'wait-and-see' strategy. With the enemy's abilities, they couldn't fail to notice this position. Waiting patiently, if he could take out another enemy, that would be perfect. Before long, Luo Zheng saw a dark figure appear in the woods ahead. He quickly searched with the sniper scope but lost track of them. Luo Zheng was startled, realizing he had underestimated these people's speed. He sharpened his focus and soon found that the enemy was already very close, their advance slowing down a bit. Luo Zheng wanted to aim and shoot but found that the opponent was changing positions too quickly, always obscured by trees, making it impossible to see. Suddenly, he remembered Lan Xue's theory about 'three trees forming a dead angle.' Upon closer inspection, he saw that each time the person changed positions, there were always three trees, or even more, blocking his view, making it impossible to effectively aim. He could only watch as the opponent drew closer. 'I must think of a way.'

Leaning against the large tree, Luo Zheng pondered and quickly surveyed his surroundings. Normally, the best course of action in such a situation would be to change sniper positions, but doing so now could easily expose him. Luo Zheng acknowledged that his speed and skills were inferior to the opponent's, and he dared not take risks. He didn't even dare to breathe heavily, let alone harbor murderous intentions, as the desire to kill could reveal one's murderous aura, and these people were very sensitive to such things, which could give him away.

Thinking of Lan Xue's teachings, Luo Zheng forced himself to remain calm, relaxing his entire body, and then relaxing further. He focused on feeling the target's speed, distance, and approximate location, and began to breathe slowly using his family's traditional breathing technique. Inhaling and exhaling evenly, softly, and slowly, he cleared his mind of all thoughts, continuously telling himself that he only had one chance to shoot.

After a while, Luo Zheng could even hear the faint, imperceptible sound of leaves crunching underfoot, and the footsteps grew closer. Luo Zheng was very clear about the opponent's strength; dodging, aiming, and pulling the trigger, these actions would take at least one second, and Lan Xue had said that one second is enough for an expert to do many things, making it impossible to hit the target.
