In addition to the massive amount of normal zombies, new mutants have also appeared in the city.
From 400 meters away, a "Giant Fat" zombie, over 5 meters tall and covered in blubber, was slowly approaching.
On the other side, a small group of "Armored Zombies," clad in armor and wielding long axes, were drifting with the current.
Not participating in the combat, Zhao Feng could only give them temporary nicknames based on their appearance.
' The mutants this time are quite ordinary; just by looking at their appearance, one can tell their general abilities. '
While he was idly pondering, a system mission prompt suddenly popped up before his eyes.
【 Ding! Temporary mission, exploration of Underground City A09 completion rate increased, current completion 1/5 】
【 Side Quest 1, Restore City Lighting, Completed 】
（ Attention! Current energy can still provide lighting for 2 hours and 43 minutes ）
【 Side Quest 2, Annihilate Zombie Tide 60,000/35,000,000 】
（ Suggestion: Utilizing the rocket gauntlets will yield unexpected rewards ）
【 Side Quest 3, Explore City Hall 】
（ Suggestion: City Hall is located on the north side of the city, where you can learn some of the secrets of this world. Double-click the mission Pathfinding Script to guide your route ）
【 Side Quest 4, Restore City Power Supply】
（ Suggestion: Please collect repair materials from the spare parts warehouse first, then proceed to the 3rd underground level for repairs. Double-click the mission Pathfinding Script to guide your route ）
【 Side Quest 5, Investigate db1000 Protein Processing Center】
（ Attention! A boss battle will unfold here. ）
The sudden appearance of side quests caught Zhao Feng off guard.
Especially the second mission.
' You must have made a mistake! With only over 2 hours, kill 35 million zombies? No matter how I utilize things, I can't possibly do it! '
Never mind the other missions, just the annihilation of the zombie tide alone had him completely stuck.
Helpless, he could only take it one step at a time.
Even if the mission couldn't be completed, at least he could grind to his heart's content here!
With so many zombies lined up, wouldn't it be a huge loss if he didn't get some kills in?
Moving to a more forward position, Zhao Feng raised his weapon and aimed at the side where the "Armored Zombies" were.
He pulled the trigger, and after a count of five seconds, a wrist-thick light blue beam was forcefully ejected from the gun muzzle.
In an instant, the beam pierced through all obstacles and directly hit the Armored Zombies.
The armor, made of some unknown material, was not immediately penetrated.
Under the continuous laser irradiation, the heat was evenly distributed across the entire armor.
It took a full second before the hit area began to show signs of melting; to penetrate it would likely require continuous irradiation for a while longer.
Sensing that the armor was unusual, Zhao Feng narrowed his eyes. He didn't continue to contend with it.
Instead, he slightly shifted his gun muzzle and swept towards the normal zombies nearby.
When the target of the attack changed to normal zombies, the laser weapon's lethality was fully unleashed.
In the blink of an eye, it pierced through the zombie horde stretching over 500 meters.
And as he continuously moved his gun muzzle, the beam swept across the entire field.
Wherever the light blue light passed, all the zombies were cut in half at the waist, joyfully suffering from paralysis.
This single attack, although it didn't kill many zombies, effectively achieved a group control effect.
It also gave Zhao Feng a glimmer of hope for completing the mission.
' Perhaps by increasing the power, making the light column thicker, and operating with more precision, they could be instantly killed. '
Before he could finish thinking, massive amounts of zombies surged out from the city, completely disregarding whether they were trampling their own kind underfoot.
They quickly filled the void created by that attack.
The zombies' eagerness to rush to their deaths made Zhao Feng's eyes light up.
He clicked on the weapon panel, selected the power option, and chose to expand the irradiation area.
As soon as the settings were complete, new weapon information popped up.
【 Ding! The current irradiation radius has been increased to 30cm, energy release factor remains unchanged, damage reduced to 18%】
【 Ding! Weapon data updated】
【 S-Type Pulse Laser Emitter Lv.1】
【 Irradiation Radius: 30cm】
【 Attack Power: 2.16】
【 Charging Speed: 5s】
Staring at the recalibrated weapon attributes, Zhao Feng was very dissatisfied.
It was clear his idea was good, but fate was not on his side.
' The attack power cannot be too low, otherwise, it won't have the effect of mowing down grass! Let's try increasing the energy release by 10% to see if it's better. '
As he made his selection again, an error message was directly thrown in his face.
【 Error: To protect the stable operation of the equipment, the default state only allows the release of 1% of the total accumulator capacity】
（ Attention! Increasing the energy release limit, besides expanding the laser irradiation area, does not additionally increase attack power. Furthermore, given the load capacity of the S-type refractive crystal, forcibly increasing energy release will permanently damage the refractive crystal! ）
（ Prompt: According to the 【 Overlord 】 issued, 《 Individual Beam Weapon Usage Standards 》, to ensure the continuous combat capability, attack power, service life, and safety of individual weapons, with the current standard power of S-type beam weapons, releasing 1% energy per discharge is the optimal solution. ）
（ Suggestion: If you wish to unlock higher power, please mount it onto a mobile combat platform, such as equipment carrying various universal or limited slots. Releasing energy beyond the limit will inevitably cause permanent damage to the refractive crystal, please use with discretion. ）
Staring at the prompt information, Zhao Feng nodded.
' Increasing the irradiation area is equivalent to enhancing attack power for me right now! '
Currently, when dealing with these zombies, the penetration power of the pulse laser is enough to paralyze them, but it's difficult to kill them directly.
On the contrary, increasing the irradiation area, turning the fist-sized light column into a basketball-sized or even a water tank-sized one.
This way, what was an awkward attack could achieve an instant kill!
As for permanent damage, Zhao Feng didn't care; as long as the equipment was used where it was needed most, it didn't matter if it broke!
Killing these zombies and getting first place on the Kill List would bring even greater benefits, definitely worth the cost!
As for Side Quest 2, Zhao Feng looked at the terrifying quantity and sighed after a long while.
' Ah, I'll just go with the flow... '
As for what a mobile combat platform is, the external prompt had basically explained it.
His gaze fell upon the gauntlet on his left hand.
He brought up the weapon panel, clicked on the slot, and attempted to mount the pulse laser emitter, only to receive another error message.
【 Strength attribute not met, unable to activate universal slot】
"Huh? That can't be right? This gauntlet even added 2 points to Strength?"
Frowning, Zhao Feng stubbornly clicked open the attribute panel to check the Strength line.
【 Strength: 4+2】
（ In addition to enhancing core strength, it increases main weapon damage by 6%. Your strength limit is 11 points. ）
"Uh... it really is a little short."
Fortunately, he had one Free Attribute point remaining.
Without any hesitation, he directly applied it.
After his Strength attribute reached 7 points, he attempted the mounting operation again, and there were no more error prompts.
【 Do you confirm mounting the S-Type Pulse Laser Emitter? Once selected, it cannot be dismantled. Forcible disassembly will damage the mounted weapon.】
（ Building a Repair Station allows for lossless disassembly. ）
' Nice! As expected of Cheat Bro! This guy really dismantled it cleanly. '
Basically, the moment the system set up an obstacle, the external system immediately provided a solution.
What was there to hesitate about?
"Confirm!"
As soon as he spoke, before Zhao Feng could even take off the gauntlet, it fully unfolded, revealing countless interfaces and slots, completely entangling the pulse laser.
After a dazzling display of transformation and mechanical friction sounds.
Mounting complete.
The gauntlet, now equipped with the S-type beam weapon, had completely changed its appearance.
In his imagination, mounting a weapon would at most mean an extra muzzle on his arm.
But the result was not like that.
