The sniper, paired with the invisibility effect, naturally stood on invincible ground; before he even fired, not even gods could find him.
Because the range of Detecting Invisibility was at most a couple hundred meters, invisible targets beyond a thousand meters had no chance of being detected.
Unless summoned units like the Chongming Bird rushed in for close reconnaissance.
However, before the sniper fired, even the approximate location remained unknown; the enemy had no idea in which direction to scout.
They didn't even know if the target existed.
Just Undead System creature; If he hadn't cast a spell, Su Muyu wouldn't have been able to pinpoint his location.
After Lin Zeyu entered the invisible state, he crept toward the southwestern mound.
Under the aerial reconnaissance of the Chongming Bird, he approached a two-kilometer range and saw the target through the scope of the Electromagnetic Accelerated Sniper Rifle.
This Horned Demon Undead Wizard was hiding in a cave; he would only emerge to cast spells, and after casting, he would retreat back into the cave for hiding.
Since he was an Undead Wizard, the sea of skeletons on the battlefield could serve as his eyes, so he was aware of every movement on the battlefield, and could control the battlefield from four kilometers away, sitting in an unbeatable position.
Lin Zeyu lay on a small mound and, through the scope, saw this Horned Demon Undead Wizard come out to cast a spell, and marked him with the Demon Hunter Mark.
With the Demon Hunter Mark locked on, even if he hid inside the cave, his red outline could already be seen.
After casting his spell, the Horned Demon Undead Wizard returned to the cave, standing in the shadows of the cave, watching the battle.
Lin Zeyu, lying on the small mound, began to move to a different position.
Although the Horned Demon Undead Wizard had hidden inside the cave, the first half of the cave was relatively straight, offering a shooting angle from outside.
Thus, Lin Zeyu started moving to find a shooting angle.
After shifting twenty meters, he found the right angle and began preparations.
Through the scope, the Horned Demon Undead Wizard was invisible since he was inside the cave.
But under the Demon Hunter Mark, a red silhouette could be seen in the darkness.
This was the great advantage of the Demon Hunter Mark, also one of the best matches for a sniper's class.
Lin Zeyu unlocked the safety on the sniper rifle, activated the skill "Plasma Armor-Piercing Bomb," aimed at the mark, and pulled the trigger.
With a gunshot, the bullet traveled at an initial velocity of 1521 meters per second, instantly covering a two-kilometer distance, flying into the shadow inside the cave.
After one shot, in Lin Zeyu's Demon Hunter vision, a portion of the red Horned Demon silhouette cracked, but did not completely shatter; it unexpectedly started running deeper into the cave.
At this point, detonating the Demon Hunter Mark could cause damage equivalent to the sniper shot, with a high probability of killing the Horned Demon Undead Wizard.
However, once the Demon Hunter Mark was detonated, if it didn't kill him, the mark would be gone, possibly allowing the target to escape.
For safety, Lin Zeyu jumped up and dashed toward the direction of the cave, and at six hundred meters distance, he pulled out the mortar and fired a "Source Energy Cloud Bomb" at the cave.
The Source Energy Cloud Bomb exploded inside the cave.
In Demon Hunter vision, he clearly saw the flames engulfing the red Horned Demon silhouette.
The red Horned Demon silhouette struggled in the flames and after a moment, stopped completely.
Lin Zeyu saw the prompt for killing the Horned Demon Undead Wizard, gained 5000 points of Demon Energy, and his Source Energy Level increased to Level 35.
Throughout the process, he hadn't even faced the Horned Demon Undead Wizard; he had fired a shot from two thousand meters away, followed by a Source Energy Cloud Bomb from six hundred meters away, and had killed the Horned Demon Undead Wizard.
After killing the Horned Demon Undead Wizard, he immediately turned and returned to the battlefield to continue sniping other Bloodline Demons.
